Mode for the Invention
[13] FIG. 1 is a plan view of a PCB coating supporter according to a preferred embodiment of the present invention, FIG. 2 is a front view, in a partial section, of the PCB coating supporter, FIGS. 3 and 4 are right and left side views of the PCB coating supporter, FIG. 5 is an exploded perspective view of the PCB coating supporter, FIG. 6 is a partially exploded perspective view of the PCB coating supporter. Hereinafter, reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
[14] Slide plates 3 and 4 are laminated on a lower plate 2 in order, and then, an upper plate 5 is laminated on the slide plate 4.
[15] The lower plate 2, the slide plates 3 and 4 and the upper plate 5 are surrounded with front and rear slide covers 6. After that, stays 7 are interposed between the lower plate 2 and the upper plate 5, so that the lower plate (2) and the upper plate (5) are securely fixed by means of fixing bolts (8) engaged with the stays. In this instance, the slide plates 3 and 4 respectively have openings 3a and 4a formed on both sides thereof to allow for a lateral slide motion of the slide plates 3 and 4 when the stays 7 are combined thereto.
[16] Supporters 10, each of which has a magnet 9 embedded in the lower end thereof, are mounted on right and left sides of the PCB coating supporter 1, and slide pushers 12 are respectively mounted on the supporters 10 through slide holes 11 formed on the supporters 10.
[17] The slide pushers 12 are respectively connected at one ends thereof with the slide plates 3 and 4, and are connected at the other ends thereof with piston rods 14 of cylinders 13 selectively operated by oil pressure or pneumatic pressure.
[18] The lower plate 2, the slide plates 3 and 4, and the upper plate 5 have coupling holes 16 and 17 vertically formed at corresponding positions and arranged at predetermined intervals so that backup pins 15 are inserted and coupled to the coupling holes 16 and 17. In this instance, the coupling holes 16 formed on the upper plate 5 and the lower plate 2 have the inner diameter substantially identical to the outer diameter of the backup pins 15, but the coupling holes 17 formed on the slide plates 3 and 4 have the inner diameter larger than the outer diameter of the backup pins 15. The coupling hole 17 may be an elongated hole in case of need.
[19] The backup pin 15 coupled to the coupling hole 16 and 17 from the upper portion to the lower portion of the coupling holes 16 and 17 includes a rubber cushion 15a combined to the top thereof, and springs 18 are respectively interposed between the backup pins 15 and the plates 2, 3, 4 and 5 to fix the backup pins 15 at the lower end of the lower plate 2 by snap rings 19.
[20] In the drawings, the unexplained reference numeral 20 designates a PCB, 21 designates lead (Pb), 22 designates a conveyer, 23 designates a screen printer, and 24 designates various circuitries.
[21] The circuitry 24 is soldered and fixed on one side surface of the PCB 20, and then, the PCB 20 is seated on the PCB coating supporter 1 of the present invention when the other side surface of the PCB 20 is coated with lead 21 using the screen printer 23 before another circuitry 24 is soldered on the other side surface of the PCB 20. In this instance, the PCB coating supporter 1 according to the present invention can stably supporter the PCB 20 in spite of a proper coating pressure. Hereinafter, a using method and an operation of the PCB coating supporter according to the present invention will be described in more detail.
[22] That is, the PCB coating supporter 1 of the present invention is seated and fixed on the conveyer 22 using the supporter 10 in which the magnet 9 is embedded. After that, when the PCB 20 on which the circuitry 24 is soldered at a side surface (see FIGS. 7 and 8), the backup pins 15 resiliently mounted on the springs 18 downwardly lower by the circuitry 24, and in this instance, as shown in FIG. 8, a height of the backup pins 15 which are located at an area where the circuitry 24 is positioned is different from a height of the backup pins 15 which are located at an area where the circuitry 24 is not positioned. In this state, to clamp the backup pins 15 at the corresponding positions before the screen printer 23 is operated, when right and left cylinders 13 are actuated, the slide pushers 12 connected with piston rods 14 push the slide plates 3 and 4 in the opposite direction to each other, so that the backup pins 15 mounted on the coupling holes 16 and 17 of the upper plate 5, the lower plate 2 and the slide plates 3 and 4 are clamped not to lower from the coupling holes 16 and 17. As described above, in a state where the backup pins 15 do not lower, the screen printer 23 coats lead 21 with a uniform pressure to perform a stable coating work on the PCB 20. In this instance, since the rubber cushions 15a are respectively fixed at the tops of the backup pins 15, namely, at end portions which are in contact with the PCB 20 and the circuitry 24, the PCB coating supporter according to the present invention can prevent damages of the PCB 20 and the circuitry 24 when lead coating work is carried out using the screen printer 23.
[23] When the lead coating work is finished, the cylinders 13 are contracted, so that the piston rods 14 and the slide pushers 12 connected to the piston rods 14 pull the slide plates 3 and 4 in the opposite direction to each other while moving backwardly to release the clamped state. Industrial Applicability
[24] As described above, the PCB coating supporter according to the present invention can clamp the backup pins 15 by a means for elevating and clamping the backup pins 15 so as to stably support the PCB 20 without regard to the circuitry 24 soldered and fixed on the PCB 20 when the side surface of the PCB 20 on which the circuitry 24 is not fixed is screen-coated with lead 21, thereby providing efficiency in screen-coating, and reducing a time period and a consumption of human power required for screen- coating work.
[25] While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
