DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] A coil having a multi-turn structure, the shape of the coil includes oval, rectangular, circular, such as Figure 1As shown, the coil includes an enameled wire 1 and an enameled wire 2, one end of the enameled wire 1 is a wire end 1, and the other end is a wire tail 1, one end of the enameled wire 2 is a wire end 2, and the other end is a wire tail 2. When the winding starts, the wire ends of the enameled wire 1 and the enameled wire 2 are wound in parallel, and two turns of the coil are completed after one layer of winding. If four turns are required, the enameled wire 1 and the enameled wire 2 are continued to be wound in parallel, and the winding is completed to form a four-turn coil, and the wire end and the wire tail of the coil are located on the same side of the coil. This method is a coil winding with an even number of layers; If three turns are required, the enameled wire 1 and the enameled wire 2 are staggered so that the two wires are wound side by side. The winding is completed as the third turn of the coil. The wire arrangement on the third turn is: enameled wire 1, enameled wire 2, enameled wire 1, ..., enameled wire 2, enameled wire 1.

The wire end and the wire tail of the coil are located on the same side of the coil. This method is used for winding coils with an even number of layers. If three turns are required, the enameled wire 1 and the enameled wire 2 are staggered so that the two wires are wound side by side. The winding is completed as the third turn of the coil. The wire arrangement on the third turn is: enameled wire 1, enameled wire 2, enameled wire 1, ..., enameled wire 2, enameled wire 1. At this time, the wire end and the wire tail of the coil are still on the same side of the coil. This method is a coil winding with an odd number of layers.

[0050] The coils of different numbers of layers are wound in the above manner, and then the electric slide 37 controls the electric clamp 38 to move downward, and the electric clamp 38 is used to cut the wire of the coil. At this time, the coil winding is completed, and the output end of the cylinder 35 is moved out of the through slot 34. The cylinder 35 releases the fixation of the push rod 41, and then the joystick 403 is manually rotated. The joystick 403 is used to manually control the rotation of the support shaft 40, so that the disc pulls the pull rod 401 to move, and pulls the push rod 41 away from the winding rod 44, so as to facilitate the removal of the coil after winding.

[0051] A coil winding method, the winding method comprising the following steps: S1, convey the wire to the operating table 3, manually fix the wire end on the winding fixture 4, and then perform the winding operation; S2. At the beginning of winding, the ends of the enameled wire 1 and the enameled wire 2 are wound in parallel. After winding one layer, two turns of the coil are completed. The winding method is as follows: S2.1. If an even number of turns is required, the enameled wire 1 and the enameled wire 2 are always wound in parallel, and after the winding is completed, the coil is wound with an even number of layers; S2.2. If an odd number of turns need to be wound, when the last turn is wound, the push block 604 is pushed by the output end of the cylinder three 603 to move the sliding plate 1 81 and the sliding plate 2 82, so that the enameled wire 1 and the enameled wire 2 are misaligned, and the two wires are wound side by side. The winding is completed, which is the last turn of the coil, and the winding of the coil with an odd number of layers can be completed.

[0052] S3. After winding is completed, the coil is manually removed to check whether the number of coil turns is qualified, and then sent to the next production process.
