Specifically, the pull pin assembly 700 includes a first pulling portion 710 and a second pulling portion 720, and further includes a pulling motor connected to the first pulling portion 710, and a pulling cylinder connected to the second pulling portion 720, where the pulling motor can drive the first pulling portion 710 to pull the shaft sleeve 590 to retract in the second direction, and the pulling cylinder can drive the second pulling portion 720 to push the ejector 570 to retract in the second direction. It can be understood that the first winding needle 530, the second winding needle 540, and the third winding needle 550 are not only relatively separated from the needle outlet sleeve 5150 during the retraction process, but also can be extracted from the wound electrical core, so that the electrical core can be transported to the next process by the blanking device.

in an embodiment, the winding device 10 further includes a needle pressing member 800, and the needle pressing member 800 is disposed on the frame 100 and is used for abutting against the needle winding assembly 500 at the second station S2 to prevent the needle winding assembly 500 from retracting in the second direction during the winding process. Preferably, the needle pressing member 800 is a rolling member, so as to reduce the friction between the needle rolling assembly 500 and the rolling member during the movement with the cam frame 210.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
