With the improvement of people's living standards, people's consumption of cars is also increasing, and the market for automobile parts is becoming larger. In recent years, automobile parts manufacturers have also been developing rapidly.

[0003] Automobile parts deformation detection is a key link to ensure the quality, safety and performance of parts, especially after processes such as stamping, welding and casting, which are prone to deformation due to stress or external force. Visual detection is a method of detecting automobile parts using machine vision technology. Through high-resolution cameras and advanced image processing algorithms, it can quickly and accurately detect the appearance defects, size and connection status of automobile parts. The existing detection device uses a movable sealing cover to move to the position of the visual detection camera and cover the lens. Under the protection of the sealing cover, dust, dirt or other impurities are effectively prevented from adhering to the surface of the visual detection camera lens, avoiding lens contamination, and also preventing the lens from being scratched or damaged by sharp objects around. Although it can provide protection for the camera, over time, the outer side of the sealing cover will still be covered with some dust, reducing the shooting effect of the lens, and the accuracy of the lens shooting will also be reduced due to the shielding of the sealing cover.
