wwvhm TERMINAL PIN INSTALLING MACHINE BACKGROUND OF THE INVENTION equipment, it is helpful to employ terminal boards which carry a large number of terminal pins. These terminal pins extend out of both sides of the board, and one side is employed for the connection of components, while the other is employed for the connection of further components or interconnection with other parts of the circuit. Additionally, some of these pins can be employed for plug-in purposes to permit the board to become a unitary card which can be simply installed and detached with respect to the balance of the circuit. Such cards are well-known and have been employed in numerous types of circuit applications, especially those requiring a large number of contacts or those requiring economic manufacture, as well as case of plug-in.
The prior art cards require the preperforation of holes through the substrate insulation board, which holes permit the insertion or installation of the contact pins. The drawback to preperforation stems from the basic need for two operative steps; first, perforation of the insulation board substrate, followed by the subsequent step of pin insertion. In some cases, it is practical to employ a board which has a large number of regularly spaced perforations therein, and wherein pins are inserted in the desired locations. However, jigging or templating is necessary so that the pins are inserted in the desired holes, leaving the other holes vacant. If this cannot be easily accomplished, the pin inserter/operator wastes a considerable amount of time in searching out the correct holes into which pins should be inserted.
The prior art structures have not accomplished pin insertion into unperforated substrate insulation board because the previous equipment was neither sufficiently sturdy nor especially equipped for that kind of operation. The wire pins must be straight, and each pin must be fully supported during the insertion step so that the necessary driving force for such insertion through a cutter through a cutting stroke and swings the driver into driving position. Downward motion of the ram causes the driver to drive the now cutoff terminal pin through the substrate insulation board, while the terminal is guided by a guide groove in the slide. In the preferred embodiment, the ram is slotted so that a new terminal pin can be driven closely adjacent a previunperforate board does not cause bending of the terminal pin. Furthermore, the driving structure itself must be sufficiently rigidized to permit the application of the adequate driving force. A particular prior art patent is US. Pat. No. 3,134,982, granted on June 2, 1964, to G. A. Gagnon et al. This prior patent is an example of a pin-inserting machine which is useful for the insertion of pins in the holes into a mounting board, but is incapable of inserting a pin through an insulation substrate which is imperforate.
SUMMARY OF THE INVENTION In order to aid in the understanding of this invention, it can be stated in essentially summary form that it is directed to a terminal pin-installing machine which is especially designed to be capable of inserting terminal pins into an imperforate insulative substrate. The machine has a frame upon which is movably mounted a power-driven ram. The ram carries a slide down with it to a predetermined position where the slide is locked to the frame. Continued downward ram movement swings ously-driven terminal pin.
Accordingly, it is an object of this invention to provide a terminal pin installing machine which is capable of inserting electric terminal pins into and through imperforate insulative substrate board. It is still another object of this invention to cut a terminal pin off a length of terminal pin material and maintain it in guided control while it is driven through an imperforate substrate board. It is a further object to provide a terminal pin-inserting machine which has sufficient structural strength and adequate control over the terminal pin to drive electrical terminal pins through imperforate electrically insulative substrate board. It is another object to provide such a machine with a frame having a ram reciprocable thereon, and a slide which is selectively secured to the ram or to the frame so that it is movable into position and locked there. It is another object to employ such a machine which incorporates a cutter associated with the slide so that, when the ram further moves with respect to the slide beyond the slide locked position, a pin is cut off of a length of terminal pin material. It is a further object to maintain full support for a cutoff pin so that, upon driving of such a pin through imperforate material, it is fully supported. It is another object of this invention to provide a driver of adequate force to drive an electric terminal pin through an imperforate insulative substrate.
Other objects and advantages of this invention will become apparent from a study of the following portion of the specification, the claims and the attached drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIGS. 1 and 3, a terminal board 10 is shown therein. Terminal board 10 comprises a substrate 12 having terminals 14 extending therethrough. In accordance with this invention, the most conveniently employed terminals are those which extend out of both sides of the substrate 12, but it is clear that, when carefully employed, the terminals can terminate substantially at one surface of the terminal boards. However, since it is clear that the terminals rely upon frictional engagement in an opening through the terminal board for their structural positioning, it is necessary for the terminals to extend fully through the terminal board for maximum terminal strength.
The substrate 12, for the purpose of this invention, is the conventional insulation board presently conveniently commercially available. It is normally a filled phenolic board of 3/32 inch thickness. The terminal pin installing machine of this invention is particularly suited for installation of pins in such substrates or boards, but it is clear that with suitable strengthening of structure, heavier pins can be driven through heavier boards. In the preferred embodiments described herein, the filled 3/32 inch phenolic insulation board is' the preferred substrate, although filled phenolic board up to A inch thick can be employed, should the need arise.
FIG. 3 shows that rows of terminals 14 can be spaced as small as dimension a, while columns of terminals can be spaced as little as b. Furthermore, as the portion of the board 12 to the right end of FIG. 3 illustrates, the terminals can be spaced in columns as little as b/2, when the terminals are staggered in the rows.
As illustrated in the prior art in FIG. 2, the prior art board 16 has terminals spaced in rows by a distance 0 and in columns by a distance d, both of which are considerably larger than the dimensions a and b, which can be accomplished by the terminal pin installing machine of this invention. The manner in which this close spacing is accomplished is a function of the slide and driver design, and will be described in detail in the specification following.
FIG. 4 illustrates a workbench having a top 18 and having an upstanding backboard 20. Terminal pin installing machines 22 and 24 are mounted on backboard 20. They are identical machines, with machine 22 shown with its movable structure in the raised position, while machine 24 is illustrated with its movable structure in the lowered position, where a terminal pin is being installed. Since the machines 22 and 24 are identical, the machine 22 will be described in more detail hereinafter.
Since the terminal board is imperforate, and it is desired that terminals be inserted in predetermined positions through the terminal board, it is necessary to form a template 26 which has a plurality of holes 28 therein, each of which corresponds to the position where a terminal pin 14 is to be inserted through the substrate board 12. In FIG. 6, the substrate board 12 is shown as being clamped upon template 26, and it is to be noted that there is no hole in the substrate board 12 corresponding to the hole 28, where a terminal pin is to be inserted. The substrate board is secured to the template by any convenient means, such as edge guides and clamps. Guide blocks 30 and 32 are identical and, accordingly, only guide block 30 will be described. The guide blocks are mounted upon workbench top 18. The top 34 of guide block 30 is flat and serves as rest surface against which the template 26 can lie. Guide pin 36 extends upward from top surface 34 and is of such diameter as to be received by the hole 28. Thus, template 26 is moved across the top of guide pin 36 until a hole is found. Thereupon, the template is moved down over the guide pin 36 until it rests on the top surface of the guide block. In this position, the substrate board 12 is positioned to receive a pin. Preferably, the substrate board 12 rests upon the top of pin 36, to provide firm support, when the terminal pin is driven. Guide pin 36 has a central hole 38 therein which receives the punchout from the substrate board and receives the portion of the terminal pin which extends through substrate 12.
Switch actuator 40 is mounted upon spring 42 so that the switch actuator 40 extends above the top surface 34, when the template 26 is not positioned. However, when the template is moved down on guide pin 36, the template depresses switch actuator 40 and spring 42. Such depressing causes closure of electric switch 44, which is in series with the terminal pin installing machine main actuating switch. Switch 44 is a safety switch and requires that the template be in position. When its serially connected main actuating switch is manually actuated by the machine operator, the machine goes through an operating cycle to drive a terminal pin. If the terminal board 12 were in the incorrect position, by not having the template down with its holes 28 embracing the guide pin, the terminal pin would be wrongly in place, but this is prevented by switch 44. As will be clear from the following discussion, the slide comes down to substantially contact thetop of the terminal board, when it is in its correct position for terminal pin driving. Thus, if the template is on the top of guide pin 36, damage would occur to the positively driven slide. Thus, electric switch 44 protects both against improper terminal placement and damage to the machine by having an improperly placed template.
The front, rear and right side elevational views of the terminal pin installing machine 22 are respectively shown in FIGS. 7, 8 and 9. Mounting bracket 46 is mounted on the backboard of the workbench and supports the machine 22. Frame 48 is the main stationary part of the machine, and is carried upon mounting bracket 46 and carries the principal parts of the machine 22 thereon. Cylinder 50 is the actuating motor of the machine 22. Cylinder 50 is a conventional type of cylinder, mounted on its lower end to frame 48.
The upper end of cylinder 50 carries control valve 52 and exhaust muffler 54. Control valve 52 is a conventional electropneumatic control valve connected to the cylinder 50 on both sides of the piston therein, to provide double acting control of piston rod 56, which is driven by the piston. Piston rod 56 is shown in its extended, lower position in FIGS. 7 through 9.
Control valve 52 has a control circuit connected thereto. The control circuit, as previously described, includes a serially connected switch 44 and the main actuating switch. The control circuit actuates valve 52 to drive the piston rod down to its extended position, shown, and in this position, limit switch 58 is actuated to signal completion of the terminal pin insertion portion of the cycle and to signal control valve 52 to return piston rod 56 and its associate structure to the raised position.
FIGS. 10, 11, 14 and illustrate the connection of the lower end of piston rod 56. The lower end of piston rod 56 carries threads 60 and upper jaw 62 is threadedly engaged thereon. The length of threads 60 permit the adjustment of upper jaw 60 upon the threads, to control the lower limits of travel of the ram and the structure carried thereon. The limit of travel is controlled by the piston on rod 56 bottoming in cylinder 50 so that piston rod 56 is at the bottom end of its stroke. Should the terminal board be absent, the nose of the ram, hereinafter described, does not come in contact with guide pin 36. Thus, some adjustment is necessary between upper jaw 62 and the piston rod. This is accomplished by adjusting the thread engagement therebetween.
Clamping is accomplished by clamp plug 64, which has a threaded end, see FIGS. 17 and 18, which engages against the thread 60 on the lower end of piston rod 56. Clamp plug 64 is prevented from turning in its recess by means of keyway 66, which is engaged by pin key 68. Additionally, clamp plug 64 is forced against the threaded end of piston rod 56 by means of set screw 70. With the set screw tightened down, the piston rod 56 cannot rotate with respect to upper jaw 62.
Lower jaw 72 is securely mounted to the top end of ram 74. Upper jaw 62 is a recess 76 and tongue 78 which respectively engage with tongue 80 and recess 82 on lower jaw 72. By this means, ram 74 is forced downward by means of its air cylinder motor 50 and is forcibly raised by the same motive means.
Ram 74 moves in guide 84, see FIG. 13, which is secured to frame 48. Ram 74 is directly connected to be actuated by the piston rod 56, as is previously described, and thus moves through its complete stroke as a function of piston rod movement. The lower terminus of ram movement is controlled by the stroke limit of the piston rod, as described above. Toward the lower end of ram 74, it is formed with slot 86, see FIG. 10, in which is mounted driver 88. Driver 88 is pivoted in slot 86 on pivot pin 90, and driver 88 carries cam dog 92 on its back side. Cam dog 92. extends through an opening in the left side of ram 74, at the bottom of slot 86. Cam dog 92 rides in slot 94 in the left side of guide 84, through most of its stroke. Toward the bottom of the stroke, cam dog 92 engages with cam face 96 to swing driver 88 to the right, from the position of FIGS.
10 and 11 to the position of FIG. 12. The purpose of this motion will be described below. Slot 86, in which driver 88 is located, extends all the way to the bottom of ram 74, as is best seen in FIG. 12. The purpose of this slot being open at the bottom end of the ram will be described hereinafter.
Slide 98 is movably mounted in a Tslot, see FIG. 13, the base of the T-slot being in frame 48. As is seen in FIG. 13, slide 98 has a slot 100 therein in which is located lock roller 102. In the position shown, the lock roller is engaged in a half-recess in ram 74 so that the ram and slide are locked together for vertical motion. However, at the desired bottom terminus of motion slide 98, there is positioned a half-recess 104 in the frame 48. When the slide moves down with the ram to this lower terminus position, which is the position wherein nose 106 of the slide is in contact with the substrate 112, as shown at the bottom of FIG. 12, lock roller 104 transfers from its half recess in ram 74 to its half recess 104 in the frame to lock the slide with respect to the frame. It should be noted, however, that ram 74 is now free to descend without the slide to its lower terminus position determined by the bottoming of the piston in cylinder 50, and the adjustment of piston rod 56 in upper jaw 62;
The terminal posts 14 are originally provided in long lengths of wire, wound on reels of a conventional nature. The preferred material, most usually used in the terminal ports of principal interest, is solder coated square steel wire. Other types of wire may be employed, but soft copper wire may not have sufficient strength to be driven through the substrate board, this depending on the nature of the substrate board, as well as the diameter, hardness and length of the particular wire terminal. The wire is furnished in the conventional reel, and the supply from the reel is indicated at 108 at the upper part of FIG. 7. Wire 108 is fed to wire straightener 110. Below straightener 110, the terminal wire 108 extends downwardly to a terminal wire channel which extends through the mechanism. The terminal wire channel is illustrated at 112 in the lower part of FIG. 11, where it extends out of the nose 106.
Cover 114, see particularly FIGS. 10 through 13, engages over wire feeder 116, which is shown in fragmentary detail in FIGS. 22 and 23. FIG. 22 illustrates the wire feeder from the rear, and shows the terminal wire channel 112 with terminal wire 108 therein. Wire feeder 116 is reciprocable up and down in its channel and carries feeder stop 118 thereon. Feeder stop 118 reciprocates between stop dog 120 and adjustable stop 122. As is seen in FIG. 22, pawl 124 is pivoted in the wire feeder 116 and engages against the terminal wire 108. Spring 126 urges the pawl in the upward, wire-engaging direction to lock terminal wire 108 against the back of wire feed channel 112. It is thus seen that terminal wire 108 is free to move downward past the pawl, but the pawl does not permit upward terminal wire movement with respect to wire feeder 116. There is sufficient friction of pawl 124 against the terminal wire 108 to draw the wire feeder 116 down to engagement by feeder stop 118 onto stop dog 120, when the wire 108 is moved downward. Upward movement of the wire causes upward movement of wire feeder 116 until feeder stop 118 engages with adjustable stop 122, whereupon upward movement of wire 108 is positively stopped.
Pivotally mounted upon slide 98 is terminal cutter 128, seen in detail in FIGS. 19, 20 and 21, and shown in FIGS. 10 and 13. Terminal cutter 128 is carried on pivot pin 130, which is mounted in slide 98. Terminal cutter 128 has the terminal wire channel 112 extending therethrough. In the central part of the terminal cutter, facing rearwardly as viewed in FIGS. 10 through 12, is a wire feeder. Roller 132 is positioned in cavity 134 and rests between the terminal wire 108, and the cavity backwall 136. The cavity backwall is slightly angularly related to the wire channel 112 in which terminal wire 108 lies, so that, as roller 132 moves upward, as seen in FIG. 20, the roller engages therebetween to lock the wire 108 in its slot. Spring 138 urges the roller in its upward direction toward the locked position. Thus, wire 108 can move downwardly through the wire feeder portion of cutter 128, but cannot move upwardly with respect thereo.
As is best seen in the lower part of FIGS. 11 and 12, terminal wire channel 112 extends out of the bottom of terminal wire cutter 120, adjacent cam face 140 which extends to the left. Dog 142 extends to the right and lies inside of guide 144 when the slide is above its lowermost position. Furthermore, when the slide reaches its lowermost position, dog 142 is released from the bottom of guide 144, as shown in FIG. 12. It is in this position that the slide is locked, with nose 106 in contact with substrate terminal board 12.
In this position, the ram 74 can continue downwardly. This downward further motion of ram 74 causes the front end of the ram to engage cam face 140 to swing the lower end of terminal cutter 128 to the right, about its pivot, to cut off the terminal wire through shear action. At the same time, the terminal wire channel at the lower end of the terminal wire cutter is swung to the right to expose the top end of now cutoff terminal 14.
With the top end of the terminal 14 now accessible, continued downward motion of the ram causes cam dog 92 on the driver to engage with cam face 96 to swing the driver from the upright position of FIGS. 10 and 11 to the active position of FIG. 12. In this position, driver web 146 swings into the terminal wire channel and engages on the top of the cutoff terminal 14. Downward motion of the ram causes the driver to thrust the cutoff terminal through the substrate terminal board 12. It should be noted that the terminal wire 14, after its cutoff, is supported on three sides in channel 112 and the angle of the driver 88 is such asto retain the cutoff terminal 14 in the back of the channel slot during the driving operation.
It must be particularly noted that driver 88 is of wider material than the terminal wire channel 112, but the driver web 146 is sufficiently narrow to engage into the terminal wire channel. This permits a strong driver, of adequate strength to drive the terminal into unperforate substrate board 12. Furthermore, it permits the employment of a terminal wire channel 112 which is of sufficiently narrow dimension to properly support the terminal wire on both sides of the channel as the terminal is being driven.
In operation, the operator secures a substrate board 12 on top of the template 26. The operator next places the template so that a hole 28 therein engages over guide pin 36 on the guide block 30. This actuates switch 44, when the template is bottomed against the top of the guide block, and upon operator closure of the operating switch, the piston 50 is energized for the downstroke. Slide 98 is locked to ram 74, and, as terminal cutter 128 moves downward, carrying feed lock roller 132, it pulls the wire downward with it, so it moves down with the slide. The wire has previously been positioned so that the front end thereof extends substantially to nose 106.
Wire feeder 116 moves downward, being pulled down by the wire, to the point where feeder stop 118 engages stop dog 120. From this point on, the wire is drawn downward through the wire feeder 116 and the wire feeder remains stationary. The slide 98 continues its downward travel until nose 106 engages on substrate 12. This was adjusted on setup by adjusting the height at the top 34 of guide block 30. At this point, lock roller 102 transfers from a lock betwe'en ram 74 and slide 98 to a lock between slide 98 and frame 48. Thus, the slide is locked in position and the ram is unlocked to move downward relatively to the slide.
Further downward motion causes the nose 148 of the ram to engage cam face 140 on terminal cutter 128. The terminal cutter is now sufficiently low so that its dog 142 is not restrained by guide 144. Thus, this right swinging of the terminal cutter 128 causes cutoff of the wire to form a cutoff terminal pin 14. This pin is restrained between the side walls of the terminal wire channel 1 12 in the nose of the slide. Further downward motion of the ram causes right swinging of driver 88 so that its web 146 is inserted into terminal wire channel 112 above the now cutoff terminal 14. Further downward motion drives the terminal through substrate board 12.
In the final downward position, limit switch 58 is actuated to recycle the cylinder to cause upward motion of ram 74. The above-described operation is substantially reversed, with the ram moving upward to permit left swinging of driver 88. Further upward motion of the ram causes transfer of lock roller 102 from the condition when it locks the slide to the frame to the condition where it locks the slide to the ram. In this condition, slide 98 moves upward with upward ram movement. The first thing that happens is that terminal cutter 128 is swung to the left, by means of dog 142 being engaged by guide 144. This lines up the portion of the terminal wire channel 112 in-the cutter with the portion of the channel in the nose of the slide. The entire structure moves upward together, until feeder stop 118 engages with adjustable stop 122. This stops wire feeder 116 to restrain the terminal wire 108. Further upward motion of the slide causes relative downward movement of the terminal wire 108 with respect to the slide. The relative amount of motion is equal to the length of the desired terminal 14, and is adjusted by adjustable stop 112. This causes relative downward motion of the terminal wire 108 so that its new bottom end is below the end of terminal cutter 128 and is positioned in the terminal wire channel in the nose of the slide. The cylinder stops in its upward terminal position, and the terminal pin inserting machine 22 is in condition for its next terminal wire insertion.
As previously discussed, ram 74 has the slot 86 which extends out of the nose 148 of the ram. This makes the bottom end of the ram channel-shaped, and the flanges of the channel are the portions of nose 148 which are active against cam face 140. However, this slot also provides a large clearance area into which a previously inserted terminal can extend. As is best seen in FIG. 12, there is a considerable amount of space in the slot 86 at the nose 148 behind the driver, so that terminals can be driven closely adjacent each other. Nose 106 and slide 98 are narrow in the front to back direction, perpendicular to the drawing sheet in FIGS. 10-12 so that rows of terminals can be closely spaced.
Adjustment of wire terminal length is accomplished by adjustment of adjustable stop 122. The adjustment of the nose 1 16 so that it stops directly against substrate 12 is accomplished by adjustment of the entire machine frame with respect to its guide block 30. Thus, the
guide block may be adjusted up and down to accomplish the desired relationship. Since the slide is locked to the frame by means of lock roller 102 in its lowermost position, adjustment with respect to the nose of the slide, when the slide is in the locked position, must be made with respect to the frame. Finally, the amount that the cutoff terminal 14 is driven through the terminal board is adjusted by the terminal position of ram 74, since the ram carries driver 88. This adjustment is accomplished by the previously described thread engagement of piston rod 56 into upper jaw 62. It is, thus, clear that all of the required adjustments can be accomplished. The spacing and positioning of the holes 28 in the template determine the position in which the terminals 14 are inserted into the substrate 412.
This invention having been described in its preferred embodiment, it is clear that it is susceptible to numerous modifications and embodiments within the ability of those skilled in the art and without the exercise of the inventive faculty.
