Description

Technical Field

[0001] The present invention relates to the field of electroplating technology, and in particular to a high-efficiency electroplating device and method for small parts. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to adhere a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics.

[0003] Nowadays, wheel-type electroplating machines are commonly used for electroplating of small parts. The surface of the roller on the electroplating machine has holes to facilitate the electrolyte to enter the drum. At the same time, after long-term use, a gap is formed between the roller and the cover, causing small parts to fall into the bottom of the tank. When the tank is full of electrolyte, it is difficult to clean it, and the parts scattered inside will affect the quality and quantity of electroplating. Summary of the invention
