[0003] When the existing workpiece is detected for defects, the camera can only detect the upper end of the workpiece and cannot detect the lower end of the workpiece, so that the defective products cannot be detected.

Two clamping plates are connected to the support frame through a clamping mechanism. The clamping mechanism comprises two square sliding grooves formed in the support frame.

[0006] Summary: For this related patent, the inventor believes that although this patent is also for detecting workpieces, the workpiece is detected by rotating the rack 360° around the ring-shaped rack driven by the second motor. However, the bottom of the workpiece cannot be detected during rotation, which may cause defective products to flow into the market. Therefore, a device that can detect the bottom of the workpiece is needed to prevent defective products from flowing into the market.
