In particular, copper ions directly affect the brightness and density of the coating. Therefore, impurity removal from the plating solution is particularly important. The commonly used method for plating solution impurity removal is chemical impurity removal. Chemical impurity removal requires the impurity remover to be evenly mixed with the plating solution to completely remove impurities. In addition, chemical impurity removal will produce particulate impurities. If particulate impurities are not removed, they can still affect the use of the plating solution. Therefore, a nickel plating tank impurity removal device is proposed. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0021] The following describes a nickel plating bath liquid impurity removal device provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0022] Example:

[0023] Combine Figure 1-4As shown, the present invention provides a nickel plating tank liquid impurity removal device, including a tank body mechanism, a stirring mechanism and a moving mechanism. The tank body mechanism includes an electroplating tank 110, an electrode rod 120 connected to both sides of the electroplating tank 110, a water pump 130 arranged on the outside of the electroplating tank 110, a circulation pipe 140 connected to both ends of the water pump 130, and a filter tank 150 arranged below the discharge end of the circulation pipe 140. The top of the filter tank 150 is hung on the side of the electroplating tank 110, and the filter tank 150 is used to filter the liquid discharged from the circulation pipe 140. The stirring mechanism includes a tooth groove 210 opened on the inner wall of the electroplating tank 110, a gear 220 rolling inside the tooth groove 210, a stirring paddle 230 coaxially connected to the gear 220, and a stirring paddle 230 rotatably connected to both ends of the stirring paddle 230. The electroplating tank 110 includes a connecting frame 240, a top plate 250 fixedly mounted on the top of the connecting frame 240, a rolling member 260 arranged at the bottom of the top plate 250 and sliding on the side of the electroplating tank 110, two groups of stirring paddles 230, and gears 220 are connected to both ends of the two groups of stirring paddles 230. The gears 220 are meshed and connected in the tooth grooves 210. The number of the tooth grooves 210 is two groups of four that match the number of stirring paddles 230. The moving mechanism includes a bracket 310 fixedly mounted on the top of the top plate 250, a linear motor 320 connected to the top of the bracket 310, a moving wheel 330 arranged on the output end of the linear motor 320, and a moving frame 340 for limiting the moving distance of the moving wheel 330. The bottom end of the moving wheel 330 is abutted against the moving frame 340.

[0024] Specifically, by utilizing the meshing of the gear 220 and the tooth groove 210, the gear 220 is driven to rotate along the tooth groove 210, thereby driving the stirring paddle 230 to rotate, achieving a stirring effect, and can quickly mix the plating solution and the impurity remover uniformly, effectively improving the efficiency of impurity removal;

[0025] In addition, a water pump 130 is provided outside the electroplating cell 110 and connected to a circulation pipe 140 to circulate the plating solution inside the electroplating cell 110 . The particulate matter and impurities therein can be removed in conjunction with the filter tank 150 , thereby improving the practicality of the device.

[0026] The working principle and usage process of the present invention are as follows: first, the device is started and the impurity remover is added. At the same time, the linear motor 320 is used to drive the moving wheel 330 to rotate, so that the top plate 250 is driven to move. At this time, the gear 220 rolls along the tooth groove 210, driving the stirring paddle 230 to rotate and start stirring. Then the water pump 130 is started to extract the plating solution inside the electroplating tank 110 and discharge it into the filter tank 150 through the top circulation pipe 140. The filtered plating solution re-enters the electroplating tank 110. After the impurity removal is completed, the filter tank 150 is removed and the nickel plating operation can be carried out again.

[0027] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
