Problems solved by technology

[0004] 1. Before the circuit board is painted, it is not convenient to fix it horizontally, which leads to the phenomenon of paint flow and dripping on the surface of the circuit board when it is tilted;
[0005] 2. It is not convenient to automatically process the double-sided painting of the circuit board through the device, and it usually needs to be manually turned over by hand, thereby increasing the labor force;
[0006] 3. When the device is in use, the time and gravity of the paint mist sprayed by the nozzle and the surface of the circuit board are not the same, which further leads to the problem of dripping and unevenness of the circuit board;

Embodiment 1

[0034] see Figure 1-6 The clamping mechanism 9 includes a pull rod 901 that is engaged with the inner side of the support plate 8, and a return spring 902 is installed on the outer side of the front end of the pull rod 901, and a rubber block 903 is fixed at the front end of the pull rod 901. The slide plate 1001 is provided with a second spring telescopic rod 1002 on the rear side of the slide plate 1001. The right side of the second spring telescopic rod 1002 is connected with a squeeze telescopic rod 1003. The rear side of 1001 and the end of the second spring telescopic rod 1002 are welded and fixed, the inner side of the slide plate 1001 and the outer side of the circuit board form a mosaic structure, the support plate 8 and the base 1 are parallel to each other, and the top of the base 1 is welded with racks on both sides of the front and back Board 101, and a mounting block 102 is welded on the inside of the base 1. The mounting block 102 is located inside the two spro...

Embodiment 2

[0036] see figure 1 , image 3 , Figure 5 and Figure 7-8 The difference from Embodiment 1 is that the adjustment mechanism 5 includes a bidirectional screw rod 501 whose bearing is connected to the inner side of the box body 3, and the outer side of the bidirectional screw rod 501 is threadedly connected with a slider 502, and a fan-shaped cavity 401 is provided above the connecting plate 4. , and the inner side of the connecting plate 4 is respectively fixed with a branch pipe 402, the top of the fan-shaped cavity 401 is connected with a paint inlet pipe 403, a through hole 404 is opened under the inner side of the connecting plate 4, and the through hole 404 and the branch pipe 402 communicate with each other, and the bottom of the box body 3 There is a connecting pipe 301 running through, and a convex groove 302 is punched at the bottom of the inner side of the box body 3, and the convex groove 302 is in the shape of a square hole. The block 502 and the box body 3 form...

Abstract

The invention discloses a circuit board spraying device, comprising a base, the inner side of the base is connected with a sprocket mechanism through a drive shaft key, the inner side of the connecting plate is provided with an adjustment mechanism that can adjust the spraying range according to the width of the circuit board, two The inner side of each of the support plates is provided with a clamping mechanism that can clamp and fix circuit boards of different widths horizontally. The clamping mechanism includes a pull rod that is engaged with the inner side of the support plate, and a rubber block is fixed at the front end of the pull rod. ; The horizontal abscission mechanism includes a sliding plate that is engaged with the inner side of the support plate. The invention can ensure that the paint on the surface of the circuit board is adhered in a uniform paint mist and with the same weight through the adjustment mechanism and the convex groove, thereby avoiding the uneven problem of the circuit board during painting. The wall is provided with a heating insulation layer, which can recycle the excess paint after cutting, thereby avoiding the waste of the circuit board during painting.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a circuit board spraying device. Background technique [0002] The names of circuit boards are: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, high-frequency boards, PCB, ultra-thin circuit boards and ultra-thin circuit boards, printed (copper etching) Technology) circuit boards, etc., circuit boards make the circuit miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. The circuit board can be called printed circuit board or printed circuit board, FPC circuit board (FPC circuit board, also known as flexible circuit board, flexible circuit board is a kind of high reliability made of polyimide or polyester film as the base material. , excellent flexible printed circuit board, with high wiring de...
