[0011] The wire outlet frame includes a base 3 and a cover plate (not shown in the figure). The cover plate covers above the base 3. Half wire grooves 30 are provided on both the base 3 and the cover plate. The half wire grooves 30 extend along a straight line. The two half wire grooves 30 on the base 3 and the cover plate face each other directly and together form a wire outlet hole. The enameled wire passes through the wire outlet hole. The base 3 has an installation groove 301 on one side of the half wire groove 30. A sliding plate 5 is provided in the installation groove 301 and can move back and forth relative to the base 3. A pair of rotatable rollers 35 are provided on the upper and lower parts of the base 3 respectively. The two rollers of each pair of rollers are respectively on both sides of the half wire groove 30, and the outer edges of the rollers are in the half wire groove 30. The two rollers 35 on the left side of the half wire groove 30 are installed on the base 3, and the two rollers on the right side are installed on the sliding plate 5 and can move together with the sliding plate 5. By moving the sliding plate 5, the distance between the two paired rollers 35 can be adjusted. The enameled wire 90 passes through the half wire groove 30, and the rollers 35 press on the enameled wire to straighten the enameled wire and improve the winding quality; during the wire routing process of the enameled wire, the rollers roll, which can reduce the friction between the enameled wire and the rollers, and the wire routing is very smooth and unobstructed; the rollers can also clamp and lock the enameled wire to prevent the enameled wire from falling out of the wire outlet frame when the enameled wire is cut short after the coil winding is completed, so as to facilitate the winding of the next coil and improve the coil winding efficiency.

[0012] The installation groove 301 is provided with a placement hole on the wall surface close to the semi-wire groove 30. The first spring 6 is placed in the placement hole under compression, and its two ends are respectively pressed against the bottom wall of the placement hole and the sliding plate 5. The sliding plate 5 has a guide rod, and the guide rod is inserted into the placement hole. The installation groove 301 is provided with a through threaded hole on the wall surface far from the semi-wire groove 30. The sliding plate 5 is provided with a receiving hole at a position directly opposite to the threaded hole. The second spring 33 is placed in the receiving hole. The bolt 34 is screwed into the threaded hole and the receiving hole from the outside of the base 3 and presses on the second spring 33. By rotating the bolt 34, the sliding plate 5 can be moved to adjust the distance between the two paired rollers, so as to lock the enameled wire or adapt to enameled wires of different diameters. During the wire routing process, the sliding plate 5 is in an elastically adjustable state between the two springs, which can make the wire routing smoother and more stable.

[0013] The two ends of the bottom coil 9 of the ignition coil are respectively docked with the right connector 22 and the left connector 23. The wire outlet frame is fixedly installed on the frame.

The winding motor 21 is started to rotate the right connector 22. The right connector 22 drives the bottom coil 9 and the left connector 23 to rotate together, so that the enameled wire is wound onto the bottom coil 9. While winding the wire, the motor 32 drives the lead screw 31 to rotate, and the moving frame 2 moves along the lead screw 31. The bottom coil 9 and the moving plate 24 move together with the moving frame 2. The bottom coil 9 rotates and winds the wire while moving axially. By moving the bottom coil to find the winding position, the windings on the bottom coil 9 can be arranged sequentially along the axis of the bottom coil, very evenly, and the winding quality is good.
