Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a water removal device for electrophoretic coating of automobile parts. Background Art

[0002] Electrophoretic coating is a coating method that uses an external electric field to make particles such as pigments and resins suspended in the electrophoretic liquid migrate in a directional manner and deposit on the surface of a substrate of one of the electrodes. It has the characteristics of water solubility, non-toxicity, and easy automatic control. At present, most of the automotive industry will use electrophoretic paint to protect automotive parts, because electrophoretic paint has a good anti-corrosion effect. By providing a dense coating, it can effectively block the intrusion of corrosive media such as water and oxygen, thereby improving the corrosion resistance of parts. In the current existing technology, after electrophoresis of automotive parts, since a large amount of water stains will adhere to the surface of automotive parts, water is generally removed by natural drying. The water removal efficiency of the above method is low, and for some parts with complex structures, there may be a phenomenon that water stains in dead corners are not completely removed. Therefore, in view of the above problems, a water removal device for electrophoretic coating of automotive parts is proposed. Utility Model Content
