[0002] Electroplating is the process of depositing a thin layer of another metal or alloy on a metal surface using electrolysis. This process involves depositing a thin metal film on the surface of a metal or other material, thereby preventing oxidation and improving wear resistance, conductivity, reflectivity, corrosion resistance, and aesthetics. Barrel plating is a process in which a large number of small parts are plated in a rolling container. Examples include zinc, copper, and high-tin bronze barrel plating on steel parts, and nickel barrel plating on copper and copper alloy parts. The solution and plating conditions for barrel plating are essentially the same as those for tank plating, though some adjustments may be made based on the material and shape of the part being plated.

The first gear 403 moves on the ring gear 404 while revolving, causing the first gear 403 to rotate around the axis of the fixed shaft 402, driving the second gear 405 to rotate and the rotating rod 501 to rotate. The rotation of the rotating rod 501 drives the cleaning block 503 to slide on the inner wall of the roller plating cylinder 103 through the connecting rod 502. By adjusting the gear ratio of the first gear 403, the ring gear 404 and the second gear 405, the differential effect between the roller plating cylinder 103 and the rotating rod 501 can be achieved, thereby adjusting the relative speed of the cleaning block 503 and the roller plating cylinder 103, extending the service life of the electroplating equipment, and reducing equipment failures and downtime caused by impurity accumulation. As the rotating rod 501 rotates, the toggle rod 505 is driven to rotate through the connecting column 504. Since the angular velocity of the toggle rod 505 following the rotation of the rotating rod 501 is faster than that of the roller plating drum 103, the toggle rod 505 can stir the workpiece in the roller plating drum 103, ensuring that the workpiece rolls and moves more evenly in the electroplating solution, thereby helping the metal ions in the electroplating solution to be more evenly deposited on the surface of the workpiece, reducing the uneven plating phenomenon.
