Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1-5 , a surface treatment device for circuit board processing, including a processing table 1, a placing plate 2 fixedly assembled on the processing table 1, a fixing plate 3 provided on the placing plate 2, a plurality of openings 7 provided on the fixing plate 3, a positioning rod 4 provided in each opening 7, a first fixing groove 5 and a second fixing groove 6 provided on the positioning rod 4, and the positioning rod 4 is connected to the fixing plate 3 through the first fixing groove 5 and the second fixing groove 6. A moving member is provided on each positioning rod 4, and the moving member is connected to the placing plate 2. A mounting bracket 14 is fixedly connected to the placing plate 2, and a fixing member for fixing the fixing plate 3 is provided on the mounting bracket 14.

[0024] Refer to Figures 3-5 , the moving member includes a sliding piece 9, a first spring 10 and a moving groove 8 provided on the placing plate 2. The sliding piece 9 is slidably connected to the inside of the moving groove 8. The sliding piece 9 is fixedly connected to the positioning rod 4. The two ends of the first spring 10 are respectively fixed to the inner bottom of the moving groove 8 and the bottom of the sliding piece 9. By using the moving member, the positioning rod 4 always moves in the axial direction, and the positioning rod 4 located at the bottom of the circuit board can move downward, thereby playing a role in positioning the circuit board in the horizontal direction.

[0025] Refer to Figure 2 , the fixing member includes two second springs 11, a connecting rod 12 and an operating plate 13. One end of the connecting rod 12 is fixed to the side wall of the fixing plate 3, the other end of the connecting rod 12 is fixed to the operating plate 13, the connecting rod 12 is disposed through the mounting bracket 14, and the connecting rod 12 is slidably connected to the mounting bracket 14. The two second springs 11 are both disposed between the operating plate 13 and the mounting bracket 14. When the staff presses the operating plate 13, the separation of the fixing plate 3 and the positioning rod 4 can be realized. After releasing the hand, under the action of the second spring 11, the inner side of the opening 7 will be stuck into the first fixing groove 5 or the second fixing groove 6, which is convenient for the staff to quickly fix the circuit board and improves the operation efficiency.

[0026] Refer to Figure 5 , the sliding piece 9 is adapted to the moving groove 8, playing a guiding role, so that the positioning rod 4 always moves in the axial direction.

[0027] Refer to Figure 5, the heights of the first fixing groove 5 and the second fixing groove 6 are adapted to the thickness of the fixing plate 3, so that the fixing plate 3 can be clamped into the first fixing groove 5 and the second fixing groove 6 to realize the fixing effect on the positioning rod 4.

[0028] Refer to Figure 3 , the cross-section of the fixing plate 3 is in a structure of a Chinese character 'hui', so that the side of the circuit board can be fixed, the positioning rod 4 at the middle position of the circuit board can be omitted, and the production cost is saved.

[0029] The specific working principle of the present utility model is as follows:

[0030] When processing the circuit board, a worker presses the pressing operation plate 13 with one hand, so that the connecting rod 12 moves and drives the fixing plate 3 to move. At this time, the second spring 11 is in a compressed state. The movement of the fixing plate 3 will cause the fixing plate 3 to disengage from the second fixing groove 6. At this time, the positioning rod 4 can move along the axial direction. Then, the circuit board is placed on the plurality of positioning rods 4 and the circuit board is pressed downwards. The positioning rod 4 at the bottom of the circuit board moves downwards, so that the sliding piece 9 moves downwards and squeezes the first spring 10. When the sliding piece 9 moves down to the limit position in the moving groove 8, at this time, the first fixing groove 5 is just located in the opening 7. At this time, the worker releases the operation plate 13. Under the elastic force of the second spring 11, the connecting rod 12 and the fixing plate 3 move in the opposite direction and reset. At this time, the first fixing groove 5 on the positioning rod 4 at the bottom of the circuit board meshes with the inner side of the opening 7, and the second fixing groove 6 on the positioning rods 4 around the circuit board meshes with the inner side of the opening 7, so as to realize the fixing of the positioning rod 4. In this way, according to the shape of the circuit board, the positioning rods 4 around the circuit board will be higher than the circuit board. These positioning rods 4 will play a role in fixing the side wall of the circuit board in the horizontal direction, preventing the circuit board from moving when the worker processes the surface of the circuit board and affecting the processing accuracy, being able to realize the rapid positioning of the circuit board, improving the operation efficiency, and at the same time being able to position and process circuit boards of different sizes and different shapes, improving the flexibility and practicability of the device.

[0031] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
