As an important part of single-crystal materials, the appearance quality of single-crystal edge skin directly affects the overall performance and reliability of products. Therefore, it is particularly important to perform efficient and accurate appearance detection on single-crystal edge skin. After a single-crystal silicon rod is cut by a diamond wire, it becomes a single-crystal square rod. After the round rod is squared, the surface appearance defects of the remaining edge skin are detected to realize the automatic recycling of the edge skin. Due to process reasons, the appearance of the remaining edge skin will have various appearance defects such as dirt, water stains, chipping, cracks, wire marks, and knife marks, which are difficult to meet the requirements of modern industrial production.

[0003] At present, in many single-crystal square rod cutting workshops in China, the method of manual visual inspection is used to detect the appearance defects of edge skin, which has the following disadvantages: First, manual detection usually requires a certain amount of time and experience. A quality inspector may need several seconds or more to check the appearance of a remaining edge skin. Second, manual detection is often based on the subjective judgment of the quality inspector. Different quality inspectors may have different understandings and judgments on the same defect, resulting in uncertainty in the detection results. Third, the quality inspector needs to stare at the edge skin for a long time, and the eyes are prone to fatigue, and the labor intensity is relatively large, which will have a great impact on both physical strength and eyesight and is difficult to meet the usage requirements of users.
