Description

Technical Field

[0001] The utility model relates to the technical field of metal material surface electroplating, in particular to a metal material surface plating device. Background Art

[0002] Surface coatings on metal materials are typically achieved through electroplating. Electroplating equipment typically includes a plating tank, a plating solution, a cathode, an anode, the object to be plated, and the plated metal. The object to be plated is connected to the cathode, and the plated metal is connected to the anode. When a voltage is applied between the cathode and anode, the plated metal releases positively charged plating metal ions, while negatively charged electrons accumulate on the surface of the object to be plated. The plating metal ions are attracted by the electrons and flow through the plating solution toward the surface of the object to be plated, where they combine with the electrons and deposit on the surface to form a coating. However, existing electroplating equipment suffers from low efficiency and is unable to simultaneously plate multiple metal parts. Furthermore, existing electroplating equipment lacks effective exhaust gas management, which can easily pollute the environment.

[0003] In order to improve the above-mentioned disadvantages, a utility model patent with the authorized public number CN210886284U in the public technology discloses a metal material surface plating device, including a plating box, a control panel is fixedly installed on the right front end of the plating box, and a control box is fixedly installed on the middle right end of the plating box. Although it can improve the working efficiency of the device and effectively treat the electroplating exhaust gas, the device still has certain minor disadvantages in actual use. For example, when the metal parts to be electroplated above the connecting rod are immersed in the electroplating box for electroplating operations, it is impossible to improve the conductivity and dispersion of the solution, promote the dissolution of the anode to improve the electroplating efficiency, and cannot effectively reduce the probability of defects such as pits and pinholes caused by hydrogen retention on the workpiece surface. The electroplating quality of the metal material surface needs to be improved. Utility Model Content
