Fig. 3 As shown, at this time, the rotary drive mechanism drives the left clamping arm and the right clamping arm to rotate, and then drives the workpiece to rotate, so that the coil is automatically wound into the groove 101 of the workpiece 10. The purpose of pulling out the guide rod is to avoid interference with the coil when the coil is wound; after the winding is completed, the translation drive cylinder drives the left clamping seat and the right clamping seat away, and the workpiece can be taken out.
