The output shaft of the rotary motor 7 faces to the left. The winding column 9 is coaxially arranged on the left end face of the output shaft of the rotary motor 7, and a wire clamping groove 10 is arranged on one side of the winding column 9. The front side of the mounting plate 4 is provided with a top wire rod 12 that cooperates with the output shaft of the rotary motor 7 through the second servo cylinder 8 on the left side of the wire through hole 5.

After such a setting, after the end of the flat wire (the wire tail 2 formed after winding into the coil 1) enters the wire clamping groove 10, the remaining flat wire can form a coil 1 around the winding column 9 driven by the output shaft of the rotating motor.

After such arrangement, after the flat wire just comes out of the wire hole 5 for a section, the wire tail side wall push rod 24 and the coil circumferential surface push rod 25 move toward each other, so that a small section of the flat wire is first bent (that is, deviated from the axis of the wire hole 5), and then, the wire tail side wall push rod 24 and the coil circumferential surface push rod 25 are both contracted (moving back to back), and then, in the process of the first servo cylinder 6 and the second servo cylinder 7 being extended, the push column 11 pushes the bent part of the flat wire into the wire clamping groove 10, and then, the rotation of the rotating motor 7 is wound into the coil 1, and at the same time, the bent part of the flat wire forms the first wire tail 2 on the coil 1 (the first wire tail 2 at this time is not corrected); then, the wire tail side wall push rod 24 and the coil circumferential surface push rod 25 move toward each other again, and the second wire tail 2 is corrected in a plane parallel to the end face of the coil 1, that is, the plane E31 on the wire tail side wall push rod 24 pushes the side wall of the second wire tail 2, that is, the plane E31 pushes; Figure 2 At the middle d, at the same time, the plane F32 on the coil circumference pushes the rod 25 Figure 2 After that, the wire tail side wall push rod 24 and the coil circumference push rod 25 move back to back again, releasing the coil 1; after that, the plane C29 on the second wire tail bottom wall push rod 22 pushes Figure 2 At point f in the figure, the plane D30 on the upper end surface of the second coil pushes the rod 23 to push Figure 2 At e in the figure, the position of the second wire tail 2 between the two ends of the coil 1 is corrected; then, the first wire tail bottom wall push rod 20 and the first coil upper end surface push rod 21 both move axially, that is, move toward the wire hole 5, so that the plane A is removed.
