The rotating end 8 is rotatably arranged on the winding tube 2 through a rotating shaft 11, and a tension spring 12 is provided between the rotating member 7 and the winding tube 2. The tension spring 12 forces the clamping end 10 to always stay away from the undercut 6; a pressing driving member is fixed on the frame 1, and the pressing driving member can act on the pressing end 9 to rotate around the rotating shaft 11, forcing the clamping end 10 to rotate toward the undercut 6, and then clamping the two ends of the coil 23 through the other end of the limit coil 23.

[0022] A slot 13 is provided at the bottom of the bobbin 2 , a first plug-in block 14 is fixed in the slot 13 , the lower end of the first plug-in block 14 extends out of the slot 13 , and the undercut 6 is provided at the bottom of the first plug-in block 14 extending out of the slot 13 .

[0023] The pressing drive member in this embodiment includes a pressing cylinder 15 and a pressing rod 16. The pressing cylinder 15 is fixed to the frame 1. The pressing rod 16 is fixed to the end of the telescopic shaft of the pressing cylinder 15. The lower end of the pressing rod 16 has an arc guide protrusion 17. More specifically, the rotating member 7 in this embodiment is in the shape of a right triangle, with the rotating end 8 located at one acute angle, the pressing end 9 located at the other acute angle, and the clamping end 10 located at the right angle.

[0024] Among them, the pressing end 9 is a first rod body extending outward, and the free end of the first rod body is provided with an arc transition portion 18, which can contact the arc guide protrusion 17, and the clamping end 10 is a second rod body extending outward, and the end face of the second rod body clamping the coil 23 is a plane 19.

After the coil 23 is wound, it is directly formed on the center column 4. One end of the coil 23 is located in the undercut 6. The downward pressure cylinder 15 drives the downward pressure rod 16 to move downward. The arc guide protrusion 17 acts on the arc transition portion 18 of the downward pressure end 9 to rotate around the rotating shaft 11 toward the undercut 6 until the other end of the coil 23 is limited by the clamping end 10 of the rotating member 7, thereby clamping the two ends of the coil 23.

At this time, the limit column 22 in the coil slot 21 corresponds to the middle column 4 up and down. After it is placed, the top cylinder 5 drives the middle column 4 upward to first pull out the coil 23. The winding tube 2 does not move. The coil 23 is continued to be limited in the fixture disk 20 by the bottom of the winding tube 2. Then the downward driving part releases the downward pressing end 9. The rotating part 7 is reset by the tension spring 12. Then the lifting cylinder 24 drives the frame 1 to move upward and reset. Repeat this operation until the coil slots 21 on the fixture disk 20 are filled with coils 23.
