Description

Technical Field

[0001] The invention belongs to the technical field of motor assembly, and in particular relates to a flat wire stator winding device. Background Art

[0002] Flat wire motors are increasingly used in the field of electric vehicles. Flat wire motors have the advantages of high copper full rate, heat dissipation of motor windings, ability to improve winding pressure resistance, and reduced winding end length, which can improve motor torque density and power density. As one of the core components of new energy vehicles, the electric drive system has an important impact on the performance of new energy vehicles. The definition of flat wire motors specifically refers to the change in the shape of the wire used in the stator winding, from multiple thin round wires to several thick rectangular wires, commonly known as flat wires. At present, flat wire conductors are mainly used in large motor equipment such as wind turbines and hydroelectric generators. In recent years, they have also been widely used in mid-to-high-end vehicle generators.

[0003] During the assembly and production process of the flat wire motor, the flat wire needs to be wound into the groove of the iron core. The existing method is to clamp one end of the flat wire and tighten the flat wire to wind it into the iron core. In this method, the flat wire is offset during winding, so that the flat wire cannot fit tightly into the groove, and it is necessary to stop the machine for adjustment many times, which seriously affects the production efficiency of the stator. Moreover, when the stator is wound in the existing method, the spacing between the flat wires in the same groove is large, which makes the copper full rate of the stator relatively low, and makes it more difficult to wind the outermost or innermost flat wire. Summary of the invention

The two limit plates 126 are in contact with and adapted to the clamping plates 125, and the spacing value between the two opposite clamping plates 125 is equal to the thickness value of the clamping wheel 156. A rectangular through hole is opened in the middle of the telescopic rod 153. Its function is to pass the flat wire to be wound through the rectangular hole in the middle of the telescopic rod 153, and the telescopic rod 153 is extended to a suitable distance, thereby driving the clamping wheel 156 to approach the iron core 19, so that the flat wire passes through the pressure rod 155 and its lower surface contacts the curved surface of the clamping wheel 156, and finally, by pushing the clamping plate 125 to both sides, one end of the flat wire passes through, and then the compression spring 124 pushes the clamping plate 125 to move toward the middle to clamp the flat wire.

[0022] Among them, the winding mechanism 15 includes a moving ring 151, and a plurality of sliding blocks 152 are slidably connected to the middle of the moving ring 151, and a telescopic rod 153 is rotatably installed in the middle of the sliding block 152, and a support block 154 is fixedly connected to the middle of the telescopic rod 153, and a pressure rod 155 is slidably connected to the lower end of the support block 154, and a clamping wheel 156 is rotatably installed on the inner end of the pressure rod 155, and a reset spring 157 is fixedly connected between the pressure rod 155 and the support block 154, and its function is that the present invention continuously drives the flat wire clamped at the lower end to be brought out from the middle of the telescopic rod 153 through the up and down movement of the moving ring 151. During the process, the telescopic rod 153 is fine-tuned and extended, so that the clamping wheel 156 and the pressure rod 155 are located in the groove of the iron core 19, and both sides of the flat wire are fitted with the inner wall of the groove, so that the flat wire cannot be offset during the winding process, thereby solving the problem of the need for adjustment due to the offset of the flat wire in the existing method.

[0023] Among them, the fixed structure 18 includes a fixed ring 181, a plurality of spacer rods 182 are clamped in the middle of the outer curved surface of the fixed ring 181, a rubber pad 183 is clamped in the bottom end of the fixed ring 181, and the top of the fixed ring 181 is fixedly connected to the movable ring 17. Its function is to slide the movable ring 17 to the uppermost end, put the iron core 19 on the middle of the rubber pad 183 below, and then press the movable ring 17 downward, thereby driving the upper fixed ring 181 and the rubber pad 183 to move downward. When the upper rubber pad 183 contacts the upper end of the iron core 19, it will push the iron core 19 to move downward until the upper and lower rubber pads 183 fix the iron core 19, so that the iron core 19 rotates with the lower connecting ring 10.

[0024] Among them, multiple adjusting gears 14 are all meshed with the ring gear 7, and the ring gear 7 is rotationally connected to the base 1. The adjusting gears 14 are all located inside the base 1, and the connecting ring 10 is rotationally connected to the base 1. Its function is that when the motor 1 4 is working, the small gear 6 on the output shaft rotates, thereby driving the meshing ring gear 7 to rotate, and the rotation of the ring gear 7 drives the meshing adjusting gear 14 to rotate, and the rotation of the adjusting gear 14 drives the threaded rod 13 to rotate, so that the moving ring 151 moves upward; when the motor 2 5 is working, the output shaft drives the large gear 8 to rotate, and the rotation of the large gear 8 drives the rotating gear 9 to rotate, and the rotating gear 9 rotates to rotate the iron core 19 and the clamping mechanism 12 to a certain angle, so that the flat wire is wrapped around the partition rod 182.

[0025] Working principle:

[0026] Before the present invention is used, the winding mechanism 15 is located at the lower part of the threaded rod 13 and the clamping wheel 156 is located between the two clamping plates 125, and the movable ring 17 and the upper fixed structure 18 are located at the most movable upper end;

[0027] When the present invention is used, the movable ring 17 is slid to the uppermost end, the iron core 19 is sleeved on the middle part of the lower rubber pad 183, and then the movable ring 17 is pressed downward, thereby driving the upper fixed ring 181 and the rubber pad 183 to move downward. When the upper rubber pad 183 contacts the upper end of the iron core 19, the iron core 19 is pushed downward until the upper and lower rubber pads 183 fix the iron core 19;

[0028] According to the winding requirements of the flat wire stator winding, the sliding block 152 is slid to the target position, that is, aligned with the groove of the iron core 19. Since the clamping wheel 156 is located between the two clamping plates 125, the sliding block 152 will drive the clamping mechanism 12 to rotate accordingly, and the flat wire to be wound passes through the rectangular hole in the middle of the telescopic rod 153. The telescopic rod 153 extends a suitable distance, thereby driving the clamping wheel 156 to approach the iron core 19, so that the flat wire passes through the pressure rod 155 and its lower surface contacts the curved surface of the clamping wheel 156. Finally, by pushing the clamping plates 125 to both sides, one end of the flat wire passes through, and then the compression spring 124 pushes the clamping plate 125 to move toward the middle to clamp the flat wire.

[0029] When the motor 1 4 is working, the small gear 6 on the output shaft rotates, thereby driving the meshing ring gear 7 to rotate. The rotation of the ring gear 7 drives the meshing adjusting gear 14 to rotate. The rotation of the adjusting gear 14 drives the threaded rod 13 to rotate, so that the movable ring 151 moves upward. The upward movement of the movable ring 151 will continuously drive the flat wire out of the middle part of the telescopic rod 153 and be located inside the groove of the iron core 19. During the process, the telescopic rod 153 is fine-tuned and extended, so that the clamping wheel 156 squeezes the flat wire and fits tightly against the inner wall of the groove of the iron core 19. The clamping wheel 156 also squeezes the reset spring 157 to prevent the flat wire from being damaged due to excessive pressure of the clamping wheel 156. When the telescopic rod 153 drives the flat wire and the clamping wheel 156 to exceed the rubber pad 183, the motor 1 4 stops working, and the motor 2 5 works. The output shaft drives the large gear 8 to rotate, and the rotation of the large gear 8 drives the rotating gear The wheel 9 rotates, and the rotating gear 9 rotates to rotate the iron core 19 and the clamping mechanism 12 to a certain angle, so that the flat wire is wound around the partition rod 182. During the process, the flat wire will drive the telescopic rod 153 and the clamping wheel 156 to rotate. When it rotates to the groove for downward winding, the motor 2 5 stops working, and the motor 1 4 works in the opposite direction to drive the movable ring 151 to move downward, so that the flat wire is wound in the corresponding groove. During the process, the clamping wheel 156 will squeeze the flat wire to fit the inner wall of the groove. The controller 2 controls the motor 1 4 and the motor 2 5 to cooperate with each other, so that the flat wire is wound in the groove of the iron core 19. After the winding is completed, the partition rod 182 is removed, and then the movable ring 17 and the fixed ring 181 are moved up to loosen the clamping mechanism 12 that clamps the flat wire below, so that the wound iron core 19 is removed, and then the partition rod 182 and the movable ring 151 are reset.
