Description

Technical Field

[0001] The utility model relates to the technical field of electrophoresis equipment, and more specifically, to a can-shaped workpiece electrophoresis electrode device. Background Art

[0002] The electrophoresis process is divided into anodic electrophoresis paint and cathodic electrophoresis paint. In workpiece painting, cathodic electrophoresis is mainly used. Its working principle is that the paint particles are positively charged, the workpiece is the cathode, and the paint particles are deposited on the workpiece to form a film. The existing cathodic electrophoresis coating equipment generally includes an electrophoresis tank, a tubular anode, and electrical equipment, etc. The tubular anode refers to the anode with an anion exchange membrane used in cathodic electrophoresis coating.

[0003] In the workpiece processing industry, the electrophoresis coating process has been widely promoted. There are can-shaped workpieces, but most of the existing electrophoresis equipment is for the electrophoresis of trailer sheet materials. Therefore, it is impossible to conveniently perform electrophoresis operations on can-shaped workpieces. The electrophoresis process cannot ensure the paint adhesion quality on the inner and outer walls of can-shaped workpieces, and manual feeding is required. At the same time, can-shaped workpieces need to be electrophoresed in batches. The lifting component of the existing electrophoresis equipment uses a hydraulic cylinder, which is prone to damage after long-term use due to the large load. Moreover, the can-shaped workpieces need to be specially dried after electrophoresis, which affects the manufacturing efficiency. Summary of the Utility Model
