When the leftmost optical lens 99 enters the placement slot 5, the positioning block 41 will block the movement of the second-to-last optical lens 99, so that the optical lenses 99 can be transported one by one. Then, the rotating block 3 rotates counterclockwise by 90°, so that the optical lens 99 in the placement slot 5 rotates to the bottom of the polishing mechanism, and the electric screw 55 works to drive the moving plate 52 along the longitudinal rod 51. It moves up and down, thereby driving the polishing motor 53 and the polishing sheet 54 to move up and down, and the polishing motor 53 drives the polishing sheet 54 to rotate to polish the optical lens 99. After polishing is completed, the rotating block 3 rotates 90° counterclockwise.
