[0021] By placing the printed circuit board fixing block 10, the two first electric telescopic rods 3 are started at the same time to move up and down, thereby driving the two second electric telescopic rods 4 to move up and down, and when they are moved to the printed circuit board, the two second electric telescopic rods 4 are started to drive the two first motors 5 and the two rubber plates 7 to move synchronously toward the printed circuit board. When the two rubber plates 7 are in contact with both sides of the printed circuit board, the printed circuit board is clamped. The rubber plates 7 are used to prevent excessive squeezing when clamping the printed circuit board, thereby preventing the printed circuit board from being damaged. When one side of the printed circuit board is painted, the fourth electric telescopic rod 11 is started to drive the rectangular plate 12 to move upward, and the third electric telescopic rod 9 is started again to move downward. When the fourth electric telescopic rod 11 and the third electric After the movable telescopic rod 9 has moved, the two first motors 5 are started at the same time, so that the two first motors 5 synchronously drive the circular plate 6 and the rubber plate 7 to rotate in the same direction, thereby driving the printed circuit board to flip over. After flipping to the other side, the first motor 5 is turned off, and the third electric telescopic rod 9 is started, so that the third electric telescopic rod 9 drives the fixed block 10 to move upward, so that the fixed block 10 contacts the bottom end of the printed circuit board, which is convenient for supporting the printed circuit board when spraying the printed circuit board to prevent the printed circuit board from shaking during spraying, and then the fourth electric telescopic rod 11 is started again to drive the rectangular plate 12 to move downward, so as to spray the other side of the printed circuit board, so as to facilitate the comprehensive plating of the printed circuit board, thereby improving the working efficiency of the plating of the printed circuit board.

[0022] like Figure 4 As shown, a fourth electric telescopic rod 11 is fixedly installed on the top of the bracket 2, and a rectangular plate 12 is fixedly installed on the output end of the fourth electric telescopic rod 11. A groove 13 is opened at the bottom end of the rectangular plate 12, and slide grooves are opened on both sides of the groove 13. A slider 14 is slidably connected inside the slide groove. A second motor 15 is fixedly installed on one side of the outer wall of the rectangular plate 12, and a screw rod 16 is fixedly installed on the output end of the second motor 15, and the other end of the screw rod 16 is rotatably connected to one side of the groove 13. The outer wall of the screw rod 16 is threadedly connected to the inner wall of the slider 14. An output pipe 17 is fixedly installed in the middle of the bottom end, and a plurality of nozzles 18 are fixedly installed at the bottom end of the outer wall of the output pipe 17. Brush plates 19 are fixedly installed on both sides of the output pipe 17 at the bottom end of the slider 14. A plating box 20 is fixedly installed on one side of the top of the workbench 1 close to the funnel 8. A scale line is provided on one side of the outer wall of the plating box 20 to facilitate observation of the plating solution in the plating box 20. A water inlet pipe is fixedly connected to the top of the plating box 20. When the plating solution in the plating box 20 is almost used up, the plating solution is added to the plating box 20 through the water inlet pipe to prevent insufficient plating solution when spraying the printed circuit board.

[0023] The rectangular plate 12 is driven to move downward by starting the fourth electric telescopic rod 11. When the two brush plates 19 come into contact with the surface of the printed circuit board, the second motor 15 is started, so that the second motor 15 drives the screw rod 16 to rotate, thereby driving the slider 14 to reciprocate with the assistance of the slide groove. When the slider 14 moves, the water pump 22 is started, so that the plating solution enters the output pipe 17 through the connecting pipe 21, so that the surface of the printed circuit board is sprayed through multiple nozzles 18. As the slider 14 moves slowly, the brush plates 19 are driven to brush the sprayed printed circuit board, so that the plating solution can be better brushed on the surface of the printed circuit board, thereby improving the plating efficiency.

[0024] like Figure 1 As shown, a connecting pipe 21 is fixedly connected to the bottom end of one side of the outer wall of the plating box 20, and the other end of the connecting pipe 21 is connected to one end of the output pipe 17. The connecting pipe 21 is a soft water pipe with a sufficiently long length. A water pump 22 is fixedly connected to the outer wall of the connecting pipe 21. A drain pipe 23 is fixedly connected to the bottom end of the funnel 8 in the middle of the workbench 1. A solenoid valve is provided inside the drain pipe 23. The sprayed excess plating solution flows into the funnel 8, and then flows into the drain pipe 23 through the funnel 8, thereby activating the solenoid valve to recycle the sprayed excess plating solution.

[0025] Working principle: When in use, the staff puts the printed circuit board fixing block 10, thereby starting the two first electric telescopic rods 3 to move up and down at the same time, thereby driving the two second electric telescopic rods 4 to move up and down, and when they move to the printed circuit board, the two second electric telescopic rods 4 are started to drive the two first motors 5 and the two rubber plates 7 to move synchronously toward the printed circuit board. When the two rubber plates 7 contact the two sides of the printed circuit board, the printed circuit board is clamped, and the rubber plates 7 are used to prevent excessive squeezing when clamping the printed circuit board, which causes damage to the printed circuit board. After clamping, the rubber plates 7 are started. The fourth electric telescopic rod 11 drives the rectangular plate 12 to move downward. When the two brush plates 19 come into contact with the surface of the printed circuit board, the second motor 15 is started, so that the second motor 15 drives the screw rod 16 to rotate, thereby driving the slider 14 to reciprocate with the assistance of the slide slot. When the slider 14 moves, the water pump 22 is started, so that the plating solution enters the output pipe 17 through the connecting pipe 21, so that the surface of the printed circuit board is sprayed through the multiple nozzles 18. As a result, the brush plate 19 is driven to brush the sprayed printed circuit board under the slow movement of the slider 14, which can better spread the plating solution. The surface of the printed circuit board is fully coated, thereby improving the plating efficiency. When one side of the printed circuit board is coated, the fourth electric telescopic rod 11 is started to drive the rectangular plate 12 to move upward, and the third electric telescopic rod 9 is started again to move downward. When the fourth electric telescopic rod 11 and the third electric telescopic rod 9 are moved, the two first motors 5 are started at the same time, so that the two first motors 5 synchronously drive the circular plate 6 and the rubber plate 7 to rotate in the same direction, thereby driving the printed circuit board to flip over. After flipping to the other side, the first motor 5 is turned off, and the third electric telescopic rod 9 is started, so that the third electric telescopic rod 9 drives the fixed block The fourth electric telescopic rod 11 is started again to drive the rectangular plate 12 to move downward, so as to spray the other side of the printed circuit board, so as to facilitate the comprehensive plating of the printed circuit board, thereby improving the working efficiency of the plating of the printed circuit board, so that the sprayed excess plating solution flows into the funnel 8, and then flows into the drain pipe 23 through the funnel 8, thereby starting the solenoid valve to recycle the sprayed excess plating solution.
