Technical Field

[0001] The utility model relates to the technical field of automobile radar bracket processing, in particular to a spraying device used for automobile radar bracket processing. Background Art

[0002] Automotive radar brackets are structural components used to secure and support automotive radar sensors. They are typically installed at the front or rear of the vehicle. Their purpose is to ensure stable operation of the radar sensor, enabling onboard radar system functions such as adaptive cruise control, collision warning, and blind spot monitoring. Before commissioning, these brackets require a spray coating. This coating provides additional protection, extending the bracket's service life in harsh environments, particularly those exposed to humidity, salt spray, or chemicals. The spray coating process typically utilizes a spray gun coupled with a robotic arm for multi-angle adjustment to ensure uniformity and coverage.

[0003] However, the common automotive radar bracket transmission belt spraying device will produce excess atomized paint during the spraying process, which is easy to pollute the surrounding environment and cause paint to adhere to the surface of the surrounding environment, while also posing a risk to the health of workers. If the paint is not dried in time, the thickness of the paint will be uneven. In view of this, we propose a spraying device for automotive radar bracket processing. Utility Model Content
