Description

Technical Field

[0001] The utility model relates to the technical field of automobile coating production lines, in particular to an electrophoretic coating power connection device. Background Art

[0002] The basic principle of cathodic electrophoretic coating is that under the action of voltage applied at the positive and negative poles, the positively charged coating ions move to the cathode surface of the workpiece of the carrier to form insoluble substances and deposit on the surface of the workpiece. At present, cathodic electrophoretic coating technology has been widely used in vehicle painting production lines. Electrophoretic coating is an extremely complex electrochemical reaction process, which is roughly divided into four parts: electrolysis, electrophoresis, electrodeposition, and electroosmosis. The entire workpiece needs the action of the electric field in the tank, so the stability and safety of the power connection device are the primary considerations.

[0003] In the existing electrophoretic coating connection process, the connection device mostly uses a whole copper disc contact connection, the friction area is too large and once the spring fails, it will have a great impact on the production and the body in the tank. Utility Model Content
