[0002] With the rapid development of the automotive industry, the types and complexity of automotive parts are constantly increasing, and the quality requirements for these parts are also becoming increasingly stringent. Part defects not only affect the performance and safety of vehicles but also lead to economic losses such as recalls and repairs. Therefore, after automotive parts are manufactured, visual inspection technology using cameras is used to detect appearance defects in the parts to prevent defects from occurring.

[0003] Currently, Chinese patent CN221326359U discloses a product defect visual inspection device, including a frame and a control cabinet. A rotating mechanism for rotating samples is installed on the upper part of the frame, and a robot is also mounted on the upper part of the frame. A vision component is installed on the robot's end shaft. The vision component includes a bracket located on the robot's end shaft. A line scanning camera is connected to a fixing hole at the end of the bracket, and a line scanning light source is connected to the front end of the bracket. A stamp is installed on the other side of the front end of the bracket. In use, the device replaces human inspection; personnel only need to load and unload materials and start the device. This example tooling achieves fully automated inspection, enabling rapid, all-around imaging of the product surface and synthesis of images. Defects are then identified through defect recognition software, reducing labor intensity and improving production efficiency. However, this technical solution cannot achieve assembly line inspection, resulting in low inspection efficiency. Utility Model Content
