Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile lamp production, especially to a dip coating device for automobile lamp shell production. BACKGROUND

[0002] The role of the dip coating device in automobile lamp shell production mainly reflects in the following aspects: 1) The dip coating device can provide a uniform coating for the lamp shell. During the dip coating process, the lamp shell is immersed in a tank containing paint, and through appropriate stirring and cooling devices, it is ensured that the paint can uniformly cover every corner of the shell. In this way, not only can the adhesion of the coating be improved, but also the thickness of the coating on the shell can be ensured to be consistent, thereby improving the overall protection performance of the shell. 2) The dip coating device can adapt to lamp shells of different shapes and sizes. The shapes and sizes of automobile lamp shells are different, and the dip coating device can adjust the size and shape of the paint tank and select appropriate dip coating methods to adapt to the needs of different shells. This makes the dip coating device have high flexibility and applicability in automobile lamp shell production. 3) The dip coating device can also improve production efficiency. Compared with traditional spraying or brushing methods, dip coating can cover the shell surface faster and the coating is more uniform.
