Description

Technical Field

[0001] The invention relates to the technical field of flat wire motors, in particular to a novel flat wire stator twisting device capable of automatically removing chips. Background Art

[0002] Flat wire motors are increasingly used because of their high slot fill rate, which can improve the power density of the motor and help reduce copper loss and temperature rise. Twisting refers to the staggered twisting deformation of the PIN pins at the end of the stator with the PIN inserted in the order of outer layer first and inner layer later. The stator of a flat wire motor generally has 48 slots, with 4 to 8 layers of flat wire in each slot. Usually, the length of the outer layer of flat wire is greater than that of the inner layer. Therefore, during the twisting process, the Z axis continues to descend at a uniform speed, and the torsion disk moves from the outside to the inside in sequence, and maintains a certain synchronization relationship with the Z axis. There are as many concentric torsion disks as there are layers of flat wire.

[0003] After searching, a composite torsion device and torsion method for flat wire windings of a motor with publication number CN111884437B is found, wherein an axial driving mechanism along the axial direction is added to the torsion device, specifically, the axial movement of the outer torsion disk during the torsion process is achieved through the first and second bosses that fit each other. However, the PIN pin heights of the stator ends of flat wire motors of different models are different. The first and second bosses in the above device have fixed structures and specifications. The bosses are used to lift the torsion disk, and the upward movement distance of the torsion disk is constant. This type of torsion disk can only twist stator windings with a specific PIN pin height. For some unconventional PIN pins, it is difficult to twist, or it is difficult to obtain the desired torsion effect after twisting.

[0004] After the twisting is completed, the PIN pin at the end of the stator needs to be moved out of the torsion disk, that is, the material is returned. When the above device is returning the material, since the upward movement and rotation of the torsion disk are interrelated, the torsion disk will also synchronously drive the torsion disk to rotate when it descends, and at this time the rotation direction of the torsion disk is exactly opposite to that during the upward movement, which will cause the PIN pin that has been twisted to be twisted in the opposite direction again, and the PIN pin after the return of the material cannot be twisted into the desired shape.

[0005] In addition, the flat wire in the flat wire stator is coated with a layer of insulating paint on the outside. During the torsion process, the friction generated by the torsion will cause part of the insulating paint on the outside of the flat wire to fall off, and the insulating paint debris will adhere to the torsion groove of the torsion disk. In the subsequent torsion process, these debris will stick to other flat wires, affecting the use of the flat wire and the performance of the flat wire motor. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when it is necessary to perform twisting processing on flat wire stators of different specifications, the heights of the PIN feet at the ends of the stators are different. At this time, the positioning seat can be moved to adjust the distance that the second connecting rod can move up and down. The closer the second connecting rod is to the center of the driving disk surface, the shorter the distance it can move up and down. The farther the second connecting rod is from the center of the driving disk surface, the longer the distance it can move up and down. By changing the movable distance of the second connecting rod, the maximum value of the up and down sliding of the transmission rod can be adjusted. At this time, the maximum axial movement distance of the torsion disk connected to the transmission rod will also change accordingly. When the PIN foot height is large, the axial movement distance of the torsion disk will be correspondingly lengthened. When the PIN foot height is small, the axial movement distance of the torsion disk will be correspondingly shortened. Therefore, the torsion disk can adapt to the needs of twisting processing of flat wire stators with different PIN foot heights. It is more convenient to use, the device has stronger adaptability, does not require a dedicated machine, and saves costs. 2. In the present invention, when the driving disk rotates half a circle, the second connecting rod also moves from the bottom of one side of the disk surface to the top of one side of the disk surface, and at this time the slide plate also moves up to the maximum height it can move, and at the same time the driving half gear running synchronously with the driving disk also rotates half a circle, at this time the end point of the driving half gear just disengages from the driven gear, the driving half gear and the driven gear are no longer meshed for transmission, and then the driving disk continues to rotate, driving the second connecting rod to gradually move downward, and other structures connected to the second connecting rod move downward synchronously, and finally driving the transmission rod to move downward synchronously, during the downward movement of the transmission rod, since the driving half gear does not mesh with the driven gear at this time, the transmission rod itself will not rotate, and the torsion disk connected to the transmission rod will not rotate either, so the twisted flat wire will not be subjected to a reverse torsional force, and the twisted flat wire can be vertically disengaged from the torsion groove to perfectly maintain the shape of the twisted flat wire; 3. In the present invention, when the flat wire is twisted in the twist groove, the flat wire will generate friction with the left and right side walls of the twist groove. At this time, the rollers provided can convert the original sliding friction into rolling friction, thereby reducing the damage of the friction to the insulating paint on the outside of the flat wire and protecting the flat wire. During a twisting process, insulating paint scraps will inevitably be generated in the twist groove. At this time, multiple air nozzles on the front and rear sides of the twist groove are used to blow air downward into the groove, so that the paint scraps attached to the groove are blown down and fall into the circular groove from the opening at the bottom of the twist groove and the corresponding through hole. Then, the paint scraps are sucked out by the use of a vacuum tube and a suction pump, thereby ensuring that the twist groove is clean and tidy, which is convenient for twisting again. 4. In the present invention, the mechanical transmission structure is used to replace the traditional industrial control software so that the torsion disk can move axially while twisting. The mechanical structure itself is more stable. At the same time, by setting the corresponding number of teeth and module in the gear transmission, the torsion and axial movement can maintain a stable synchronous relationship. Compared with setting an independently operated Z-axis motion platform, this mechanical structure is less prone to errors and the torsion processing effect is better.

A dual-axis synchronous motor 619 is provided on the front side of the driving disk 618, one output end of the dual-axis synchronous motor 619 is connected and fixed to one end of the rotating shaft of the driving disk 618, and a pulley 616 is fixed to the other output end of the dual-axis synchronous motor 619, a transmission shaft 620 is provided on the side of the driving disk 618 corresponding to the rotating shaft 611, a transmission shaft 620 is provided on the outside of the transmission shaft 620, and the transmission shaft 620 is rotatably connected to the inside of the chassis 1 through the transmission shaft sleeve 621 on its outside, a pulley 616 is fixed to the end of the transmission shaft 620 close to the driving disk 618, the pulley 616 on the transmission shaft 620 and the pulley 616 on the output end of the dual-axis synchronous motor 619 are connected by a belt 617, a driving bevel gear 615 is fixed to the end of the transmission shaft 620 away from the pulley 616, a driven bevel gear 614 is fixed to the bottom end of the rotating shaft 611, and the driving bevel gear 615 is meshed with the driven bevel gear 614 for transmission; A plurality of guide grooves 630 are formed on the inner wall of the slide 610 at equal intervals and pass through the slide 610. A guide bar 629 is fixed on one side of the rod body of the transmission rod 66 corresponding to the plurality of guide grooves 630. The plurality of guide bars 629 are respectively slidably connected in the corresponding guide grooves 630. The guide bars 629 and the guide grooves 630 are used in coordination, so that the transmission rod 66 can slide more smoothly when sliding up and down. At the same time, when the slide 610 rotates, the transmission rod 66 can be driven to rotate synchronously. In this embodiment, in the initial stage (i.e., the flat wire is placed in the torsion groove 36, but the torsion has not yet begun), the slide plate 63 is located at the lower end of the slide groove 62, and the slide plate 63 is at the limit position (the lowest point) at which it can move downward. At this time, the starting point of the driving half gear 612 (that is, the first tooth, see the attached Fig.13) just starts to contact with the driven gear 68, but has not started to mesh and transmit, then the dual-axis synchronous motor 619 starts to run, driving the driving disk 618 to rotate, in the initial stage, the second connecting rod 627 is also located at the bottom, as the driving disk 618 rotates continuously, it will drive the second connecting rod 627 to gradually move up, the linkage plate 624 and the first connecting rod 626 connected to the second connecting rod 627 will also move up synchronously, the first connecting rod 626 is rotatably connected to the slide plate 63, when the first connecting rod 626 moves up, it will drive the slide plate 63 to move up synchronously, the rotating drum 64 connected to the slide plate 63 and the transmission rod 66 rotatably connected in the rotating drum 64 will move upward synchronously with the slide plate 63, when the transmission rod 66 moves upward, it will push the supporting disk 31 connected thereto upward, so that the supporting disk 31 and the torsion disk inside it move axially upward, without the need to set up an additional Z-axis motion platform, but it can achieve a similar effect of synchronously moving the Z-axis during the torsion process; As the dual-axis synchronous motor 619 continues to operate, the transmission shaft 620 at the other end of the dual-axis synchronous motor 619, which is connected to the transmission through the belt 617 and the pulley 616, will continue to rotate. The transmission shaft 620 drives the rotating shaft 611 and the driving half gear 612 on the rotating shaft 611 to rotate through the bevel gear structure. As the driving half gear 612 continues to rotate, it will gradually mesh with the driven gear 68 and start to transmit, driving the driven gear 68 to rotate. The driven gear 68 is sleeved and fixed on the slide 610. When the driven gear 68 rotates, the slide 610 will move synchronously. The transmission rod 66 is slidably connected in the slide 610. When the slide 610 rotates, the transmission rod 66 is driven to rotate synchronously, and the first internal gear 371 and the second internal gear 381 fixed on the top of the transmission rod 66 rotate synchronously with the transmission rod 66. When the first internal gear 371 and the second internal gear 381 rotate, the corresponding first outer gear ring 372 and the second outer gear ring 383 rotate synchronously, and then the corresponding torsion plate rotates synchronously in the opposite direction. At this time, the flat wire in the torsion groove 36 is torsionally deformed with the rotation of the torsion plate. When the driving disk 618 rotates half a circle, the second connecting rod 627 also moves from the bottom end of one side of the disk surface to the top end of one side of the disk surface, and at this time, the slide plate 63 also moves up to its maximum height (highest point) that it can move. At the same time, the active half gear 612 that runs synchronously with the driving disk 618 also rotates half a circle. At this time, the end point of the active half gear 612 (that is, the last tooth, see the attached Fig.13) just disengages from the driven gear 68, the driving half gear 612 and the driven gear 68 are no longer meshed for transmission, and then the driving disk 618 continues to rotate, driving the second connecting rod 627 to gradually move downward, and other structures connected to the second connecting rod 627 move downward synchronously, and finally driving the transmission rod 66 to move downward synchronously. During the downward movement of the transmission rod 66, since the driving half gear 612 is not meshed with the driven gear 68 at this time, the transmission rod 66 itself will not rotate, and the torsion disk connected to the transmission rod 66 will not rotate either, so the twisted flat wire will not be subjected to a reverse torsional force, and the twisted flat wire can be vertically disengaged from the torsion groove 36 to perfectly maintain the shape of the twisted flat wire. The mechanical transmission structure replaces the traditional industrial control software so that the torsion disk can move axially while twisting, and the mechanical structure itself is more stable. At the same time, by setting the corresponding number of teeth and module in the gear transmission, the torsion and axial movement can maintain a stable synchronous relationship. Compared with setting an independently operated Z-axis motion platform, this mechanical structure is less prone to error and the torsion processing effect is better; When it is necessary to perform twisting processing on flat wire stators of different specifications, the heights of the PIN feet at the ends of the stators are different. At this time, the positioning seat 625 can be moved to adjust the distance that the second connecting rod 627 can move up and down. The closer the second connecting rod 627 is to the center of the drive disk 618, the shorter the distance it can move up and down, and the farther the second connecting rod 627 is from the center of the drive disk 618, the longer the distance it can move up and down. By changing the movable distance of the second connecting rod 627, the maximum value of the up and down sliding of the transmission rod 66 can be adjusted. At this time, the maximum axial movement distance of the torsion disk connected to the transmission rod 66 will also change accordingly. When the PIN foot height is larger, the axial movement distance of the torsion disk will be correspondingly longer, and when the PIN foot height is smaller, the axial movement distance of the torsion disk will be correspondingly shortened. Therefore, the torsion disk can adapt to the needs of twisting processing of flat wire stators with different PIN foot heights, is more convenient to use, and the device has stronger adaptability. It does not require a dedicated machine, which saves costs.
