Description

Technical Field

[0001] The utility model relates to the field of appearance detection, in particular to an appearance defect detection device. Background Art

[0002] As the largest electronic consumer product, mobile phones are becoming more and more popular. When people buy mobile phones, they have high requirements for the appearance of the product. The main appearance parts can be divided into three categories: the display surface, the middle frame surface, and the back glass surface. Compared with the other two categories, the middle frame surface is prone to defects during production and assembly due to its irregular structure and less complex features. Especially when there is an arc surface on the middle frame surface, it requires multi-angle light sources to detect it. In the actual production process, the detection is more difficult, and manual detection alone is prone to missed detection. Therefore, in the detection process, it is integrated with visual inspection technology to perform appearance inspection on the frame workpiece.

After the photographing is completed, the workpiece is unloaded and the next frame workpiece is photographed and inspected. The inspection speed is slow and the efficiency is low, which is very inconvenient. Utility Model Content
