[0002] The inspection of existing workpieces is generally completed through a visual inspection system, wherein the visual inspection system specifically includes an inspection camera and a light source device. When using vision to inspect workpieces, there may be multiple inspection items. For example, the inspection of button batteries not only detects appearance defects, but also detects the characters on the workpiece. Appearance defect detection requires the use of a low-angle light source, while character recognition detection requires the use of a high-angle light source. Since the existing light source device can only provide a single light source, it is impossible to provide a high-angle light source and a low-angle light source at the same time. If you want to complete the appearance defect detection and character recognition detection of the workpiece, you need to pass through the inspection station with a low-angle light source and the inspection station with a high-angle light source in turn to complete it, and the inspection efficiency is very low.
