[0001] This utility model relates to the field of tire inspection technology, specifically to a visual inspection device for tire defects. Background Technology

[0002] After automobile tires are manufactured, their outer tread pattern and inner surface need to be inspected to avoid defects that could affect product quality. Currently, both the inner and outer surfaces of automobile tires can be inspected using images captured by cameras for analysis to determine if defects exist. However, in actual inspection, while industrial cameras can detect the tread pattern on the outer surface, subtle scratches and other defects on the inner surface of automobile tires are not easily detected during the initial leak detection stage. Furthermore, the arched shape of the tire's inner wall makes it difficult to detect visual defects during visual inspection, thus affecting the accuracy of the inspection. Utility Model Content
