Description

Technical Field

[0002] In the field of electric vehicle manufacturing, the painting process of electric vehicle lampshades is of vital importance. With the continuous advancement of technology, paint sprayers are widely used in the painting operations of electric vehicle lampshades. However, when spraying paint on the lampshade, the existing paint sprayer usually fixes the lampshade on a fixture and uses a spray gun to perform static spraying. Since the lampshade is in a stationary state, the spray gun can only spray from a specific angle, which can easily lead to uneven paint spraying and easy to cause missed spraying or heavy spraying. Therefore, an automatic rotation device for the fixture is developed. However, the fixture of the existing automatic rotation device for the fixture is usually directly clamped on the side of the lampshade, resulting in the clamping part of the lampshade being unable to be painted. The staff is required to perform auxiliary painting, which increases the workload of the staff and greatly reduces the working efficiency of the paint sprayer to a certain extent. In order to solve the shortcomings of the existing technology, we propose an automatic rotation device for the fixture of the electric vehicle lampshade shell sprayer. Utility Model Content
