A liquid pump 202 is fixedly installed on the top of the fixing frame 5. The input end of the liquid pump 202 is communicated with the liquid storage barrel 201. The output end of the liquid pump 202 is communicated with a corrugated pipe 203. A spray pipe 204 is fixedly installed inside the movable frame 6. The surface of the spray pipe 204 is communicated with the bottom of the corrugated pipe 203. A rotating shaft 205 is rotatably connected inside the movable frame 6. A cleaning wheel 206 is fixedly installed on the surface of the rotating shaft 205. Gears 207 are fixedly installed on both sides of the rotating shaft 205. Toothed plates 208 are fixedly installed on both sides of the top of the processing table 1. The gears 207 are located on the top of the toothed plates 208 and mesh with the toothed plates 208.

[0023] The effects achieved by the above components are as follows: By providing the liquid storage bucket 201 for storing the cleaning liquid, the cleaning liquid inside the liquid storage bucket 201 is pumped out under the action of the liquid pump 202 and introduced into the inside of the spray pipe 204 through the corrugated pipe 203. The cleaning liquid is sprayed onto the circuit board through the nozzles at the bottom of the spray pipe 204, playing a role in cleaning the circuit board. When the movable frame 6 moves, the movable frame 6 drives the rotating shaft 205 and the cleaning wheel 206 to move together, causing the gear 207 to rotate on the top of the toothed plate 208, thereby driving the cleaning wheel 206 to rotate, so that the cleaning wheel 206 cleans the circuit board and improves the cleaning effect on the circuit board.

[0024] As Figure 3 shown in the figure, the driving mechanism 3 includes a motor 301. The motor 301 is fixedly installed on the back surface of the fixed frame 5. A screw rod 302 is fixedly installed at the output end of the motor 301. A threaded sleeve 303 is fixedly installed at the top of the movable frame 6.

[0025] The effects achieved by the above components are as follows: By providing the motor 301 for driving the screw rod 302 to rotate, the screw rod 302 drives the threaded sleeve 303 to move, the threaded sleeve 303 drives the movable frame 6 to move, and further the movable frame 6 drives the cleaning mechanism 2 to reciprocate on the circuit board, improving the cleaning and filtering of the cleaning mechanism 2 on the circuit board.

[0026] As Figure 3 shown in the figure, guide rails 7 are fixedly installed on both sides of the top of the processing table 1. The guide rails 7 are respectively located between the limit angle plates 9 and the toothed plate 208. The bottom of the movable frame 6 is located inside the guide rails 7.

[0027] The effects achieved by the above components are as follows: By providing the guide rails 7 for limiting the movement of the movable frame 6, preventing the movable frame 6 from moving and shifting, resulting in the tilting of the cleaning mechanism 2 and affecting the cleaning effect of the cleaning mechanism 2 on the circuit board.

[0028] As Figure 3 shown in the figure, pulleys 8 are provided on both sides of the bottom of the movable frame 6. The surface of the pulleys 8 is in contact with the bottom inside the guide rails 7.

[0029] The effects achieved by the above components are as follows: By providing the pulleys 8 for reducing the friction between the bottom of the movable frame 6 and the guide rails 7, reducing the resistance when the movable frame 6 moves, and thus facilitating the driving of the cleaning mechanism 2 to move.

Support blocks 12 are fixedly installed on both sides of the inner cavity of the processing table 1. A collection box 11 is arranged inside the processing table 1 and on top of the support blocks 12.

[0032] The working principle of this kind of brush cleaning device for circuit board circuit etching:

[0033] The motor 301 drives the screw 302 to rotate. Then, the screw 302 drives the threaded sleeve 303 to move. The threaded sleeve 303 drives the movable frame 6 to move. Further, the movable frame 6 drives the cleaning mechanism 2 to reciprocate on the circuit board. Under the action of the liquid pump 202, the cleaning liquid in the liquid storage barrel 201 is pumped out and introduced into the interior of the spray pipe 204 through the corrugated pipe 203. Then, the cleaning liquid is sprayed onto the circuit board through the nozzles at the bottom of the spray pipe 204, playing a role in cleaning the circuit board. When the movable frame 6 moves, the movable frame 6 drives the rotating shaft 205 and the cleaning wheel 206 to move together, causing the gear 207 to rotate on the top of the toothed plate 208, and then driving the cleaning wheel 206 to rotate, so that the cleaning wheel 206 cleans the circuit board.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, based on the above description, other different forms of changes or variations can be made. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
