[0001] The present invention relates to the technical field of motor winding machines, and in particular to a new energy vehicle motor winding machine and a winding method thereof. Background Art

[0002] New energy vehicle motor winding machine is a kind of equipment specially used for manufacturing stator winding of new energy vehicle motor. It uses an automated process to embed copper wire or copper flat wire into the stator core slot according to a specific winding method to form the motor winding. The automated production process of the new energy vehicle motor winding machine not only improves production efficiency, but also ensures the consistency and stability of product quality, which helps to reduce costs and improve user satisfaction. New energy vehicle motors are one of the core components of new energy vehicles such as electric vehicles, hybrid vehicles and fuel cell vehicles. Their main function is to convert electrical energy into mechanical energy to drive the vehicle. When processing motor windings, traditional winding machines usually use bundled wire harnesses to wind around the stator core. This winding method has some disadvantages. First, the bundled wire harnesses are arranged unevenly, which will affect the uniformity of the winding thickness and may affect the performance and efficiency of the motor. Secondly, the gap between the bundled wire harnesses is difficult to control accurately, which may lead to reduced power density and efficiency of the motor, because the gap between the wire harnesses is crucial to the thermal management and electromagnetic performance of the motor. Therefore, in response to the above problems, a new energy vehicle motor winding machine and a winding method thereof are proposed. Summary of the invention

[0021] Working process: To prevent the wiring harness 11 from being stacked irregularly during winding work and to ensure the gaps between the wiring harnesses 11, first fix the stator body 9 and prevent the stator body 9 from being on the top of the placing table 26. Start the first electric telescopic rod 25 to drive the placing table 26 and the stator body 9 to rise. When the stator body 9 is between the two side arc plates 27, start the two hydraulic rods 23 at the same time to push the side arc plates 27 to move toward the stator body 9. The movement of the side arc plates 27 drives the second telescopic rod 24 to extend. The second telescopic rod 24 supports and stabilizes the side arc plates 27. After the two side arc plates 27 clamp the stator body 9, start the first electric telescopic rod 25 to drive the placing table 26 to move downward. When the placing table 26 is away from the stator body 9, The stator body 9 can be wound, and the center of the stator body 9 is on the same vertical line as the center of the lower ring shell 35. At this time, the stator body 9 can be accurately fixed to ensure that the accuracy of the stator body 9 winding is not affected. The end of the wire harness 11 is fixed at any part close to the iron core of the stator body 9. At the same time, some distance is reserved for the wire harness 11, and the third servo CNC motor 66 is started to drive the fixed wheel rod 67 to rotate. The fixed wheel rod 67 drives the fixed pulley 68 on the outside to rotate, and the pulley 68 drives the belt 691 on the outside to rotate. The pulleys 68 and the belt pay-off assembly 69 on the left and right ends are both provided with two groups, which can improve the stability of the bobbin 693 when rotating. The rotation of the belt 691 drives the fixed inner straight hole block 692 on the outside to rotate. The inner straight hole block 692 drives the wire drum 693 fixed on the inner side to rotate. When the wire drum 693 rotates, the wire harness 11 moves from the wire through hole 694 opened on the inner side of the wire drum 693, and the wire harness 11 will flow along the activity trajectory of the wire through hole 694 close to one end of the iron core of the stator body 9. The other end of the wire harness 11 is fixed to the outer side of the middle end of the pay-off wheel 51, and the wire harness 11 is wound around the outer side of the pay-off wheel 51. When the wire harness 11 is wound around the outer side of the iron core of the stator body 9 along the activity trajectory of the wire through hole 694, the wire harness 11 will pull the pay-off wheel 51 to rotate. The wire harness 11 is pulled out of the pay-off wheel 51 by pulling. When winding, the second servo CNC motor 44 is started at the same time, and the second servo CNC motor 44 drives the second gear 45 to rotate. The wheel 45 drives the third gear 46 meshing on the outside to rotate, and the third gear 46 drives the double-threaded rod 47 fixed on the inside to rotate. The rotation of the double-threaded rod 47 drives the internally spirally connected internally threaded cylinder 61 to move, and the internally threaded cylinder 61 moves the side seat block 62 to move, and the side seat block 62 drives the first telescopic rod 10 to extend. The first telescopic rod 10 plays a role in limiting the movement of the side seat block 62. At this time, the first rotating winding assembly 6 and the second tensioning assembly 7 move simultaneously in the direction of approaching each other. After the surface of the core of the stator body 9 is coiled with one layer, the main shaft of the second servo CNC motor 44 is started in the reverse direction, and the core of the stator body 9 is wound again. By controlling the main shafts of the second servo CNC motor 44 and the third servo CNC motor 66 to rotate,The belt unwinding assembly 69 can ensure the friction between the belt 691 and the pulley 68 by tensioning the elastic telescopic assembly 65. When the two core windings of the stator body 9 are completed, the bottom end of the stator body 9 is contacted with the placing table 26 when the core windings of the other two stator bodies 9 are completed, so that the side arc plate 27 and the stator body 9 are loosened, and the servo motor at the top of the first electric telescopic rod 25 is controlled, so that the stator body 9 is driven to rotate through the placing table 26, and the stator body 9 is fixed by the side arc plate 27, so as to realize the control of the activity trajectory of the wire harness 11, thereby ensuring the regularity of the winding, and at the same time ensuring the consistency of the spacing between the wire harnesses 11, ensuring that the power density and efficiency of the motor are not affected; When the wire harness 11 is kept in a tensioned state, the same principle as above applies. When the wire harness 11 appears in the moving track of the wire through hole 694, the wire harness 11 will pull the pay-off wheel 51 to rotate. The moving hour hand of the rotating wire harness 11 is the same as the hour hand of the wire harness 11 wound on the pay-off wheel 51. The pay-off wheel 51 is rotatably connected to the outside of the empty ring 55 through a bearing. When the pay-off wheel 51 rotates, it drives the clockwork spring 53 to rotate. Under the pulling action of the pay-off wheel 51, the clockwork spring 53 maintains an elastically contracted state. When the elastic force of the clockwork spring 53 shrinks to the limit, the triangular clip 54 slides out of the triangular clip groove 56 under the action of the tension. Under the action of the elastic force, the triangular clip 54 is again stuck in another triangular clip groove 56, so as to keep the wire harness 11 in a tensioned state when it comes out, and ensure that the wire harness 11 at one end of the stator body 9 and the wire through hole 694 will not be loose, and ensure the stability and accuracy of the winding of the stator body 9. To realize the iron core of the stator body 9 of different sizes and to adjust the size of the belt pay-off assembly 69, the second electric telescopic rod 63 is started to drive the dovetail edge block 64 to move. When the dovetail edge block 64 moves forward, the distance between the front and rear ends of the belt 691 becomes longer, and the distance between the upper and lower ends of the belt 691 becomes shorter. When the dovetail edge block 64 moves backward, the distance between the front and rear ends of the belt 691 becomes shorter, and the distance between the upper and lower ends of the belt 691 becomes longer. When the shape of the belt 691 changes, the movable guide column 655 is driven to move through the pulley 68 and the fixed wheel rod 67. The movable guide column 655 moves through the margin The moving block 654 is slidably connected to the inner side of the limited rail groove 653 opened in the inner hollow shell 651. The setting of the margin moving block 654 and the limited rail groove 653 plays a role in limiting the fixed wheel rod 67, preventing the moving guide column 655 from rotating inside the inner hollow shell 651 to drive the fixed wheel rod 67 to rotate. Under the elastic force of the vertical spring 652, the tensioning performance of the pulley 68 on the belt 691 can be ensured, thereby ensuring that the friction between the pulley 68 and the belt 691 is increased. At this time, the activity trajectory of the wire through hole 694 can be adjusted according to the size of the belt 691, thereby achieving the effect of adjusting according to the size of the stator body 9 iron core, thereby improving the applicability of the device; When adding the wiring harness 11 to the pay-off wheel 51, the electric cylinder 31 is started to drive the load-bearing support plate 34 to move upward, and the load-bearing support plate 34 drives the third telescopic rod 33 to shrink. The third telescopic rod 33 can improve the stability of the load-bearing support plate 34, and the load-bearing support plate 34 drives the device at the bottom to move upward as above. At this time, one end of the new wiring harness 11 is pressed and fixed to the outer side of the middle end of the pay-off wheel 51 by bolts, and the first servo CNC motor 37 is started to drive the first gear 38 to rotate. The rotation of the first gear 38 drives the outer meshing rack 42 to rotate, and the rack 42 drives the passive disk 41 to rotate. The passive disk 41 is connected to the multi-ring limit groove opened in the lower ring shell 35 through the double ring adjustment 43. The inner side of 36 plays a role in limiting the rotation of the passive disk 41. The rotation of the passive disk 41 drives the first tensioning assembly 5 to rotate as a whole through the empty ring 55. At the same time, the passive disk 41 drives the first rotating winding assembly 6 to rotate as a whole through the first telescopic rod 10. The structure of the second tensioning assembly 7 is the same as that of the first tensioning assembly 5, and the structure of the second rotating winding assembly 8 is the same as that of the first rotating winding assembly 6. The second tensioning assembly 7 and the second rotating winding assembly 8 will also rotate at the same time. When the pay-off wheel 51 rotates, the pay-off wheel 51 can automatically wind the wire harness 11, thereby achieving the effect of adding material to the wire harness 11. The adding material process is simple to operate and efficient.
