[0026] Specifically, the clamping and positioning block 5 is installed at the end of the rotating module to fix the workpiece; the reducer 6 is linked with the servo motor 7 to control the flipping angle accuracy; and the servo motor 7 drives the ball screw 9 and the rotating module to move.

[0027] exist Figure 1 and Figure 2 In the middle, the clamping and positioning block 5 is installed at the end of the rotating module.
