[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance and enhancing aesthetics. In electroplating, a solution containing plating metal cations is required as the plating solution to maintain the concentration of the plating metal cations. The plating solution mainly includes main salt, conductive salt, buffer, chelating agent, and additives. Different plating solutions have different component ratios. After the plating solution is proportioned, it needs to be mixed and stirred by a stirring device.

In addition, the device is not convenient for discharging the material after the stirring process is completed, which affects its use. Therefore, it does not meet the existing needs. In this regard, we propose a stirring device for the plating solution. Utility Model Content
