Description

Technical Field

[0001] This invention relates to the field of industrial robot technology for spraying, and particularly to an industrial robot for spraying automotive parts. Background Technology

[0002] In the automotive parts manufacturing sector, the application of industrial robots has greatly improved production efficiency and product quality. Especially in the painting process, industrial robots, with their advantages of high precision, high stability, and repeatability, have become key equipment for achieving efficient and uniform painting of automotive parts.

[0003] Existing industrial robots used for automotive parts painting lack adequate protective structures at the joint rotation points. During painting, a large amount of paint mist permeates the working environment, and these joint rotation points of existing industrial robots typically have gaps without proper protection. This allows paint mist to easily seep into the robot's joints. Once the paint mist seeps into the joint gaps, it gradually accumulates and solidifies, significantly increasing friction at the joint rotation points. This not only affects the robot's normal joint rotation flexibility, reducing the robot's motion accuracy and impacting the quality and uniformity of the painting, but may also accelerate the wear of joint components, shortening the robot's lifespan.
