[0002] With the continuous development of society, the electroplating industry has developed rapidly. Electroplating is a process of plating a thin layer of other metals or alloys on the surface of certain metals by using the electrolysis principle. It is a process of making a metal film adhere to the surface of metal or other material parts by using electrolysis, which plays the roles of preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance and enhancing beauty. When processing and manufacturing products such as PCBs, ceramic chips and silicon wafers, it is necessary to carry out plating work on their surfaces. When putting the alloy into the electroplating bath, an electroplating jig is needed. An electroplating jig is a special tool used to fix the workpiece to be plated in the electroplating process. During electroplating, the workpiece needs to be firmly fixed on the jig so that a uniform and dense metal coating can be formed on the surface of the workpiece under the action of electrochemical reaction.

[0003] For example, an electroplating jig with the publication number of CN220724396U in the prior art can realize the flexible clamping of solar cell wafers by setting elastic clamping members, avoiding the problems of breakage and hidden cracks of solar cell wafers and improving the yield rate of electroplated solar cell wafers.
