Description

Technical Field

[0001] The utility model relates to the technical field of electrophoresis, in particular to a micro-arc electrophoresis coating coating device. Background Art

[0002] The main principle of micro-arc electrophoresis is to generate instantaneous high temperature and high pressure through arc discharge, so as to oxidize the metal ions on the metal surface and in the electrophoresis fluid to produce a high-quality coating. The coating produced by micro-arc electrophoresis is relatively uniform and fine, and is often used on ships and aviation components.

[0003] For example, Chinese patent CN219824389U discloses a titanium alloy micro-arc oxidation treatment device, which includes a metal mesh for supporting a workpiece and a connecting tube and a conductive sheet for conducting electricity. The electrolyte is poured into the interior of the treatment device body and energized, and the cations in the electrolyte pass through the metal mesh plate and adhere to the surface of the workpiece.

[0004] However, after electrophoresis, the liquid on the surface of the workpiece needs to be cleaned in time, and some workpieces with more complex shapes often have some liquid remaining in their grooves, so it is difficult for the device to automatically clean the liquid on the surface of the workpiece; and there is a high voltage in the electrophoresis process, so it is difficult for the device to automatically transport the workpiece and connect the circuit, which poses a safety hazard.
