[0033] Example

[0034] like Figures 1-6 As shown, the present invention proposes an anti-silver discoloration electroplating equipment, including a tank body 1 and a stirring assembly 12 installed in the tank body 1. The stirring assembly 12 is provided to stir the plating liquid in the tank body 1 to achieve sufficient and uniform contact with the electroplated workpiece, thereby achieving uniform electroplating treatment. A plating liquid circulation pipe 13 for circulating and filtering the plating liquid is also installed on one side of the tank body 1. The plating liquid circulation pipe 13 allows the plating liquid to circulate between the electroplating tank and the filter; an anode assembly 11 is also installed on the inner wall of the tank body 1. The anode assembly 11 is used to supply power. A lifting cylinder 2 is provided above the tank body 1 to lift the upper part of the tank body 1. The square is fixedly connected to a fixed frame with an inverted "U"-shaped structure, the lifting cylinder 2 is fixedly installed on the fixed frame, the output end of the lifting cylinder 2 is connected to the lifting frame 21, and the bottom of the lifting frame 21 is fixedly connected to the connecting plate 22; a plurality of supporting frames 3 are also installed at the bottom of the lifting cylinder 2, and a connecting column 31 is provided between the upper and lower layers of the supporting frame 3, and the connecting column 31 is used to be fixedly connected to the two layers of supporting frames 3, and the top of the connecting column 31 is threadedly connected to a connecting cap 32, and the top of the connecting cap 32 is fixedly connected to the bottom plate wall of the connecting plate 22. The supporting frame 3 is provided with two layers, and a plurality of cathode clamp assemblies 4 are installed in an array on the two layers of supporting frames 3.

[0035] like Figure 3 、 Figure 4 and Figure 5 As shown, the cathode clamp assembly 4 includes two groups of symmetrically arranged fixed columns 41, and the two groups of fixed columns 41 are semicircular structures. A first groove 42 and a second groove 43 are respectively provided on both sides of each group of fixed columns 41. A clamping plate 47 is provided on one side of the first groove 42, and multiple groups of first springs 46 are installed in the first groove 42 in an array along its height direction. The other end of the first spring 46 is connected to the clamping plate 47. The two groups of clamping plates 47 are used to clamp the plate-like workpiece. A guide rod 48 is fixedly connected to the side of the clamping plate 47 close to the first groove 42.
