Description

Technical Field

[0001] The utility model relates to the technical field related to electrophoretic coating, and in particular to an anti-shaking electrophoretic coating workpiece positioning device. Background Art

[0002] Electrophoretic coating is a coating technology that uses an external electric field to make the pigments and resin particles suspended in the electrophoretic liquid migrate in a directional manner and deposit on the substrate surface of one of the electrodes. The basic principle of this technology is that the resin in the cathode electrophoretic coating has alkaline groups, which are soluble in water after being neutralized with acid to form salts. When direct current is passed, the negative ions of the acid radical move to the anode, while the resin ions and the pigment particles wrapped in them move to the cathode with positive charges and deposit on the cathode, thus completing the electrophoretic coating process. During the coating process, the workpiece is moved on the production line by a positioning device, and passes through multiple processes in sequence. The positioning device can fix the workpiece for easy coating.

[0003] In the existing coating technology, the workpiece positioning devices are mostly suspended on the production line. During the movement, the workpiece shakes due to uneven speed or other factors. Multiple workpieces collide during the shaking process, resulting in poor coating effect of the workpieces, affecting the quality of electrophoretic coating. Summary of the invention
