[0023] A box body 6 is provided on the side of the electroplating tank 1, and a liquid inlet pipe 7 is connected to the bottom of the box body 6, and the other end of the liquid inlet pipe 7 is connected to the pump body 8.

[0024] Working principle:

[0025] like Figure 1-3As shown, before using the electroplating tank liquid stirring and filtering device, the tank liquid is first injected into the electroplating tank 1, and the liquid level of the tank liquid cannot be higher than the height of the liquid inlet hole 10. After the tank liquid is injected, the electroplating operation can be started;

[0026] During the electroplating process, the pump body 8, the servo motor 14 and the rotary motor 17 are started, the rotary motor 17 drives the rotating shaft 18 to rotate, the rotating shaft 18 drives the second bevel gear 21 to rotate, the second bevel gear 21 drives the first bevel gear 20 to rotate, thereby driving the stirring shaft 4 to rotate, the pump body 8 extracts the tank liquid in the electroplating tank 1 through the liquid outlet pipe 9, and discharges it into the box body 6 through the liquid inlet pipe 7. As the liquid level of the tank liquid increases, the tank liquid will pass through two filter screens 11 with decreasing mesh sizes from bottom to top in sequence, the filter screen 11 will filter out impurities contained in the tank liquid, and when the liquid level of the tank liquid in the box body 6 rises to the height corresponding to the liquid inlet hole 10, the filtered tank liquid will flow back into the electroplating tank 1 again;

[0027] When the servo motor 14 rotates forward, it will drive the screw 15 to rotate forward, and then drive the moving block 2 threadedly connected to the screw 15 to move upward. When the servo motor 14 rotates reversely, it will drive the screw 15 to rotate reversely, and then drive the moving block 2 threadedly connected to the screw 15 to move downward, and then let the moving block 2 drive the slide 19 to move upward or downward in the second slide hole, thereby driving the rotating shaft 18 to move upward or downward. The moving block 2 also drives the stirring shaft 4 to move upward or downward, so that the stirring blades 5 on the stirring shaft 4 can fully stir the entire tank liquid in the electroplating tank 1. The forward and reverse mode switching of the servo motor 14 belongs to the existing technology and will not be elaborated here.
