具体实施方式 DETAILED DESCRIPTION

下面结合附图对本发明作进一步详细说明。 Below in conjunction with the accompanying drawings of the present invention will be described in further detail.

参见附图，本发明包括储液槽1以及与储液槽1相连通的由计算机9控制的蠕动泵2，蠕动泵2通过管路与分点布置的喷头3相连通，在分点布置的喷头3的正下方还设置有缸体7以及与缸体7紧密配合的由计算机9控制的活塞8，活塞8的上表面与缸体7的内圆柱面形成的空间作为容纳树脂的树脂槽，在活塞8的上端与缸体7的开口在同一水平面的位置还设置有刮板6以及与刮板6相连接的换能器5和由计算机9控制的超声波发生器4。 Referring to the drawings, the present invention includes a reservoir and a reservoir communicating with the peristaltic pump controlled by a computer 9 2 2 by a peristaltic pump tubing and nozzle arrangement 3 points communicated, arranged in points just below the nozzle 3 is also provided with 8, the upper surface of the piston 8 and the inner cylindrical surface of the cylinder space of the piston 7 is formed by a control computer 9 and a cylinder 7 and the cylinder 7 closely with the resin as the resin tank housing, In the upper end position of the piston of the cylinder 8 at the same level of the opening 7 is also provided with a transducer 6 and the blade 6 is connected with the blade 5 and by the computer 9 controlled the ultrasonic generator 4.

在制作中，当一层树脂固化完成后，在计算机9的控制下活塞8向下移动一层厚距离，蠕动泵2在计算机9的控制下通过导管在储液槽1中抽取定量的树脂，再通过导管输送到分点布置的喷头3，向由活塞8的上表面与缸体7的内圆柱面形成的树脂槽内补充定量树脂，使补充的树脂恰好填满活塞8下降后形成的空间，树脂补充完后，由计算机9控制超声波发生器4通过换能器5将振动传输给刮板6上，刮板6沿水平方向进行刮平运动，完成刮平动作，完成树脂薄层的均匀涂敷，制件全部制作完成后，活塞8可以升到最顶端。 In production, when the layer of resin curing is complete, move under computer control piston 8 9 distance down a thick, peristaltic pump 2 under the control computer 9 by quantitative extraction of resin ducts in the reservoir 1, and then transported through the conduit to the nozzle arrangement 3 points, to complement quantitative resin resin tank from the upper surface of the piston and the cylinder 8 is formed within the cylindrical surface 7, so just add the resin to fill the space formed after the fall of the piston 8 The resin add finished, the computer 9 controls the ultrasonic generator 4 through the transducer 5 6 vibration transmitted to the blade, blade 6 along the horizontal direction Calibrating movement, complete evenness action, complete uniform thin layer of resin coating, all parts after production is completed, the piston 8 can rise to the top.

本发明为了避免成型工作台在升降运动时扰动树脂以引起液面的波动，将原来分开制作的树脂槽及工作台制造成一体化形式的，即由活塞式结构组成。 The present invention in order to avoid disturbing the resin molding stage when lifting motion to cause fluctuations in the level of the manufacture of the original production of the resin bath and separate table into the form of integration, that is, from the piston-type structure. 当活塞8向下运动时，活塞8与缸体7之间的空隙可盛装树脂，而活塞8即可作为成型时的工作台。 When the piston 8 downward, the gap 8 between the piston and the cylinder 7 can be dressed resin, while the piston 8 can be used as table molding. 这种结构一是节约树脂，克服了原来结构中不论制作大小零件都必须有一定量的树脂存放在树脂槽内。 First, this structure saves resin overcome the original structure regardless of the size of the parts produced must have a certain amount of resin deposited in the resin tank. 二是当活塞8(工作台)上升或下降运动时，不会扰动树脂，从而引起树脂液面的波动。 Second, when the piston 8 (table) up or down movement, not disturbing the resin, causing fluctuations in the level of the resin.

在零件制作过程中，一层固化完成后，活塞8(工作台)下降一个层厚的距离，为了保证液面的位置固定不变，必须向树脂槽内补充树脂。 In the production process of the part, one after curing is complete, the piston 8 (table) decreased from a layer thickness, in order to ensure the position of the liquid level constant, the resin must be added to the resin tank. 本发明采用可精密控制流量的蠕动泵向树脂槽内补充，并且根据制作零件的截面形状，在不同位置以液滴或雾状的形式补充到树脂液面内，以防止集中补充造成刮平时树脂的过量堆积，影响涂层的精度。 The present invention uses a peristaltic pump to precisely control the flow of the resin tank supplement, and a cross-sectional shape of the production of parts, in different locations in the form of droplets or mist into the resin liquid supplement to prevent centralized supplement usually caused by scraping resin excessive accumulation, affect the accuracy of the coating.

树脂完成后，由刮板6进行刮削运动辅助液面尽快流平，以提高涂层的精度，刮板6由超声波发生器4控制是可以进行超声波振动的刮板，其优点是在刮削过程中，超声波的振动可以降低树脂的粘度，改善树脂的物性，从而可以实现更小的涂层厚度。 After the resin is completed by the scraping blade 6 auxiliary surface leveling movement as soon as possible to improve the accuracy of the coating, blade 6 4 ultrasonic generator can be controlled by the ultrasonic vibration of the blade, the advantage is in the process of shaving , the ultrasonic vibrations can reduce the viscosity of the resin, improved physical properties of the resin, which can achieve a smaller thickness of the coating.
