[0025] Please refer to Figure 1 A reinforcing column 24 is provided in the middle position inside the machine cover 1, and a reinforcing support is provided on the top of the support frame 5. The present invention makes the machine cover 1 have better support through the reinforcing column 24, and the reinforcing support makes the support frame 5 have better support.

[0026] Working principle: turn on the power, the movable wire end clamping jaws 22 respectively clamp the wire ends led out from the wire nozzle 16, the lower wire mold clamping jaws 17 extend forward and insert into the middle of the two lower wire molds 15 to hold the wire ends, place the iron core 14 on the upper part of the lower wire mold 15, and the two iron core support plates 10 are used to hold the iron core 14. The two groups of upper clamping plates 12 and lower clamping plates 13 move toward the direction of the iron core 14, thereby fixing the upper and lower end surfaces of the iron core 14. At the same time, the starting wire end heating clamping jaws 18 are closed, and the upper sliding wire mold removal clamping jaws 6 move the two upper sliding wire molds 7 fixed thereon downward and insert them into the upper side of the iron core 14 and then retreat. The lower wire mold clamping jaws 17 retreat, and the wire nozzle 16 moves toward the longitudinal gap between the two groups of upper sliding wire molds 7 and the lower sliding wire mold 15. At this time, the vertical plane formed by the two wire nozzles 16 The symmetrical surface of the gap between the left and right molds of the sliding wire mold coincides with that of the two wire nozzles 16, so that the two wire nozzles 16 enter the gap formed by the left and right sliding wire molds from the lower sliding wire mold 15 and move upward. When the wire nozzles 16 move upward to a certain distance from the tip of the upper sliding wire mold 7, the wire nozzles 16 start to rotate while moving upward, and the two groups of wire nozzles 16 respectively hang the wires on the left and right molds of the upper sliding wire mold 7. When the wire nozzles 16 rotate to 90°, the wire nozzles 16 start to move downward while continuing to rotate. When the wire nozzles 16 rotate 180°, they stop rotating. At this time, the two groups of wire nozzles 16 pull the wires hung on the upper sliding wire mold 7 back and move downward. The two copper wires will slide into the iron core 14 from the upper part of the iron core 14 under the guidance of the two groups of upper sliding wire molds 7 as the left and right groups of wire nozzles 16 move downward. In the left and right groups of slots, when the wire nozzle 16 moves downward to a certain distance from the tip of the lower wire mold 15, the two wire nozzles 16 continue to move downward and rotate in the opposite direction, so that the left and right wire nozzles 16 wind the wire around the left and right molds of the lower wire mold 15. When the wire nozzle 16 rotates in the opposite direction to about 90°, the wire nozzle 16 rotates in the opposite direction and moves upward. When the wire nozzle 16 rotates in the opposite direction to 180°, the rotation stops, and the left and right wire nozzles 16 continue to move upward while pulling the left and right wires. The left and right copper wires will slide from the lower part of the iron core 14 into the left and right slots of the iron core 14 under the guidance of the lower wire mold 15 as the left and right wire nozzles 16 move, and then repeat the above movement until the iron core slots are full of wires, and the wire nozzle 16 stops below the sliding wire mold and rotates The wire hooks 21 are rotated to a certain angle so that the vertical planes where the two wire nozzles 16 are located are basically coincident with the vertical planes where the two groups of wire hooks 21 are located. At this time, the two groups of wire hooks 21 move forward, hook the copper wire between the iron core 14 and the wire nozzles 16 from the left and right sides respectively, and pull them backwards, so that there is a section of copper wire between the iron core 14 at the upper position and the wire nozzles 16 at the lower position on the left and right sides and the wire hooks 21. The end wire heating clamps 20 on the left and right sides are closed, respectively clamping a section of copper wire between the iron core 14 at the upper position on the left and right sides and the wire hooks 21 (i.e., the end wire of the wire turn of the iron core 14). The movable wire end clamps 22 on the left and right sides move to one side of the end wire heating clamps 20 and respectively clamp a section of copper wire between the wire nozzles 16 at the lower position on the left and right sides and the wire hooks 21.The wire scissors 23 on the left and right sides advance to cut the wire between the wire nozzle 16 and the iron core 14 pulled by the wire hook 21, so that the upper and lower wire sections are disconnected at the wire hook 21, and the movable wire end clamps 22 on both sides clamp the wire ends of the lower wire and retreat, and the left and right coil shaping molds 8 advance toward the iron core 14 to press the wound coil, and the wire straightening pressing plates 19 on the left and right sides are pressed down and retreated, and the two sets of starting wire end heating clamps 18 and ending wire end heating clamps 20 are powered on for heating, and the yellow light flashes as a warning until the heating is completed for a few seconds, and the air nozzle 9 blows air to cool the wire end, and the lower wire mold clamp 17 extends forward and is inserted between the two molds of the lower wire mold 15. Holding the core 14, the wire nozzle 16 rotates a certain angle so that the vertical plane where the two wire nozzles 16 are located is parallel to the left and right sides of the machine cover 1. At the same time, the movable wire end clamps 22 on both sides move to the side close to the starting wire end heating clamp 18, the upper sliding wire mold removal clamp 6 moves down to clamp the upper sliding wire mold 7, the left and right sets of coil shaping molds 8 retreat, the upper sliding wire mold removal clamp 6 clamps the upper two upper sliding wire molds 7 and moves up, the cylinder 11 drives the coil shaping mold 8 forward, the two sets of upper clamps 12 and lower clamps 13 both retreat, and the coil shaping mold 8 retreats. At this point, a stator winding is completed and the product can be taken out manually.

[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.
