Platinum gold has a wide range of applications in the fields of jewelry, electronics, automobiles, aerospace, etc. due to its excellent physical and chemical properties, such as high corrosion resistance, good catalytic performance, and beautiful appearance. The platinum-gold plating electroplating line ensures that the workpiece surface obtains a high-quality platinum gold plating layer through a series of processing steps.

[0003] The working principle of the platinum-gold plating electroplating line is to immerse the workpiece to be electroplated as the cathode together with the anode into an electrolyte containing platinum gold ions. By applying direct current, platinum gold ions are reduced and deposited on the surface of the workpiece to form a plating layer. During electroplating production, the fixture installation cabin is convenient for transporting and fixing the material to be electroplated when it is lying down, but air bubbles are not easy to discharge when it is placed for electroplating, affecting the quality of electroplating. When the fixture installation cabin is turned over on the turnover tank, the fixture installation cabin is easy to shake or not well positioned, which is not convenient for alignment and transportation. The traditional butt joint structure often connects and fixes the fixture installation cabin through mechanical structure, which may cause safety hazards due to wear or failure of mechanical parts. Therefore, a platinum-gold plating electroplating line is proposed. SUMMARY
