Description

Technical Field

[0001] This utility model relates to the field of electroplating tank technology, and specifically to an electroplating tank with uniform electroplating solution concentration. Background Technology

[0002] After the production of automotive component housings is completed, electroplating is required. Electrolysis is used to coat the surface of metal or other material parts with a metal film, which serves to prevent metal oxidation, increase hardness, prevent wear, improve conductivity, smoothness, heat resistance, and surface aesthetics. The process is typically carried out in an electroplating tank. The workpiece to be plated acts as the cathode, and the plating metal or other insoluble material acts as the anode. Both are placed in the electroplating tank containing the plating solution. When electricity is applied, the cations of the plating metal are reduced on the surface of the workpiece to form the plating layer.

[0003] However, in actual electroplating operations, the concentration of metal ions in different parts of the electroplating solution is uneven, resulting in uneven metal plating and affecting the quality of the metal plating. In order to ensure the uniformity of the coating, improve the deposition rate and optimize the stability of the plating solution, a stirring structure is usually set in the electroplating tank to achieve uniform electroplating by disturbing the electroplating solution. However, the actual reaction process is around the cathode of the workpiece. The existing stirring structure has a fixed position and cannot be adjusted according to the position of the cathode, which is inconvenient to use.

[0004] Based on this, the present invention designs an electroplating tank with uniform electroplating solution concentration to solve the above problems. Utility Model Content
