Description

Technical Field

[0001] This utility model relates to the field of electroplating roller technology, and in particular to a highly corrosion-resistant electroplating roller. Background Technology

[0002] Electroplating is a process that uses the principle of electrolysis to plate a thin layer of another metal or alloy onto the surface of certain metals. In barrel plating, the barrel is a crucial component, significantly impacting the quality of the plating. The barrel is equipped with electroplating solution guide holes to facilitate the exchange of plating solution inside and outside the barrel. During the electroplating process, the barrel is partially or completely immersed in the plating solution and rotates axially. While the parts are tumbling and being electroplated in the solution, the workpiece inside the barrel remains within the barrel and is simultaneously subjected to the plating solution entering through the holes on the panel under the tumbling action of the barrel.

[0003] The existing Chinese patent document CN201320558974.2 discloses an electroplating roller. The contact area between the roller body and the cover body is provided with a transition structure to prevent the parts to be plated from getting stuck at the contact area. By setting a transition structure at the contact area between the roller body and the cover body, the inner wall of the roller body and the cover body can be smoothly transitioned. The parts located inside the roller body will not get stuck at the contact area between the roller body and the cover body during the roller plating process, thereby improving the electroplating quality of the parts located inside the roller.

[0004] However, the above-mentioned patent has certain defects in use. The roller of the device is not easy to remove impurities attached to the roller surface. After the roller has been used for a long time, the impurities will block the through holes on the roller, thus affecting the quality of the barrel plating.

[0005] To address these issues, a highly corrosion-resistant electroplating roller is proposed. Utility Model Content
