Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an automobile parts electrophoretic paint processing hoisting device. Background Art

[0002] After automotive parts are processed and formed, they need to be painted. The current painting method for automotive parts is electrophoretic painting, which involves moving the automotive parts into an electrophoretic tank through a transportation mechanism. Direct current is then passed through the electrophoretic paint in the tank, causing the electrophoretic paint to be deposited on the surface of the automotive parts under the action of the electric field. Compared with traditional painting methods, electrophoretic paint has good uniformity and can form a very uniform and smooth coating on the surface of the workpiece, avoiding the uneven thickness that may occur with ordinary spraying. In addition, electrophoretic paint has a high utilization rate and can almost completely adhere to the workpiece, resulting in less paint waste.
