Background

Electroplating is a process of plating a thin layer of other metals or alloys on the surface of some metals by utilizing the electrolysis principle, and is a process of adhering a metal film on the surface of the metal or other material parts by utilizing the electrolysis so as to play roles of preventing the metal from being oxidized (such as rust), improving the wear resistance, conductivity, reflectivity, corrosion resistance (such as copper sulfate and the like), improving the beauty and the like. The outer layer of the coins is electroplated;

after electroplating is completed, clamping is needed by an automatic clamping device; for example, patent number (CN 202221196726.3) discloses a clamping device for a workpiece for metal plating processing, which includes a slide rail, and is characterized in that: a sliding groove is formed in the middle of one side wall of the sliding rail, and two clamping arms are connected to the inner side wall of the sliding groove in an up-down symmetrical mode in a sliding manner; the side walls of one opposite sides of the two clamping arms are fixedly connected with limiting clamping blocks, the two limiting clamping blocks are arranged in an up-down symmetrical mode, and a plurality of limiting grooves are formed in the side walls of one opposite sides of the two limiting clamping blocks in a horizontal equidistant mode from one side to the other side; the two clamping arms are fixedly connected with threaded connecting seats on the side wall of one side, which is away from the side, the two threaded connecting seats are arranged in an up-down symmetrical mode, and a threaded groove is formed in the center of the side wall of the other side, which is away from the side, of the two threaded connecting seats;
