Description

Technical Field

[0001] This invention relates to the field of flat wire motor technology, specifically a novel flat wire stator torsion device with automatic chip removal capability. Background Technology

[0002] Flat wire motors are increasingly widely used due to their higher slot fill factor, which increases power density and helps reduce copper loss and temperature rise. Twisting refers to the alternating twisting deformation of the pins at the stator end with inserted pins, in the order of outer layer to inner layer. Flat wire motor stators typically have 48 slots, with 4-8 layers of flat wire per slot. Usually, the outer layer of flat wire is longer than the inner layer. Therefore, during the twisting process, the Z-axis descends continuously and uniformly, and the twisting discs move sequentially from the outside in, maintaining a certain synchronization with the Z-axis. The number of concentric twisting discs corresponds to the number of layers of flat wire.

[0003] A search revealed a composite torsion device and method for flat wire windings in a motor, published under publication number CN111884437B. This method involves adding an axial drive mechanism along the axial direction to the torsion device, specifically using a first and second boss that engage with each other to achieve axial movement of the outer torsion disc during the torsion process. However, different models of flat wire motors have varying stator pin heights. The first and second bosses in the aforementioned device have fixed structures and specifications. The distance the torsion disc moves upward is constant, as the bosses lift it. This type of torsion disc can only torsion stator windings with specific pin heights. For some non-standard pin heights, it is difficult to torsion, or the desired torsion effect is difficult to achieve after torsion.

[0004] After the pins at the stator end are twisted, they need to be removed from the twisting disc, which is called unloading. When the above device unloads the material, since the upward movement and rotation of the twisting disc are related, the twisting disc will also rotate synchronously when it descends. At this time, the rotation direction of the twisting disc is exactly opposite to that during its upward movement. This will cause the pins that have already been twisted to be twisted in the opposite direction again, and the unloaded pins cannot be twisted into the desired shape.

[0005] In addition, the flat wires in the flat wire stator are coated with a layer of insulating varnish. During the twisting process, the friction generated by the twisting will cause some of the insulating varnish on the outside of the flat wire to fall off. The insulating varnish debris will adhere to the twisting groove of the twisting disc. In the subsequent twisting process, these debris will stick to other flat wires, affecting the use of the flat wires and thus affecting the performance of the flat wire motor. Summary of the Invention

[0018] As a further embodiment of the present invention: a circular groove is provided on the top of the machine platform, the torsion mechanism is movably disposed in the circular groove, and one end of the suction pipe penetrates the inner wall of the machine platform and extends into the circular groove.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. In this invention, when different specifications of flat wire stators need to be torsion processed, the pin heights at the stator ends are different. At this time, the positioning seat can be moved to adjust the vertical movement distance of the second connecting rod. The closer the second connecting rod is to the center of the drive disk surface, the shorter its vertical movement distance; the farther the second connecting rod is from the center of the drive disk surface, the longer its vertical movement distance. By changing the displacement distance of the second connecting rod, the maximum vertical sliding value of the transmission rod is 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 height is large, the axial movement distance of the torsion disk will be longer; when the pin height is small, the axial movement distance of the torsion disk will be shorter. Thus, the torsion disk can adapt to the needs of torsion processing of flat wire stators with different pin heights. It is more convenient to use, the device has stronger adaptability, does not require special machines, and saves costs.

[0021] 2. In this invention, when the drive disc rotates half a turn, the second connecting rod also moves from the bottom of one side of the disc to the top of the other side of the disc. At the same time, the slide plate also moves up to its maximum height. Simultaneously, the active half gear, which runs synchronously with the drive disc, also rotates half a turn. At this time, the end point of the active half gear just disengages from the driven gear, and the active half gear and the driven gear no longer mesh. Then the drive disc continues to rotate, causing the second connecting rod to gradually move down. Other structures connected to the second connecting rod move down synchronously, eventually causing the transmission rod to move down synchronously. During the downward movement of the transmission rod, since the active half gear does not mesh with the driven gear at this time, the transmission rod itself will not rotate, and the torsion disc connected to the transmission rod will not rotate. Therefore, the twisted flat wire will not be subjected to a reverse torsional force, and the twisted flat wire can be vertically detached from the torsion groove, perfectly maintaining the shape of the twisted flat wire.

[0022] 3. In this invention, when the flat wire is twisted in the twisting groove, the flat wire will rub against the left and right side walls of the twisting groove. At this time, the rollers can convert the original sliding friction into rolling friction, reducing the damage to the outer insulating varnish of the flat wire and protecting the flat wire. During the twisting process, insulating varnish debris will inevitably be generated in the twisting groove. At this time, multiple air nozzles on the front and rear sides of the twisting groove blow air downwards into the groove, blowing the varnish debris attached to the groove downwards and falling into the circular groove through the opening at the bottom of the twisting groove and the corresponding through hole. Then, the varnish debris is sucked out by the combined use of the suction pipe and the suction pump, thereby ensuring that the twisting groove is clean and tidy, and is easy to twist and use again.

[0023] 4. In this invention, a mechanical transmission structure replaces traditional industrial control software, enabling the torsion disc to rotate and move axially simultaneously. 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 movements can maintain a stable synchronous relationship. Compared with setting an independently operating Z-axis motion platform, this mechanical structure is less prone to errors and the torsion processing effect is better. Attached Figure Description

Detailed Implementation

[0039] The following embodiments will describe the present invention in detail with reference to the accompanying drawings. In the drawings or description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this invention are merely illustrative and not intended to limit the scope of the invention. Any obvious modifications or changes made to this invention do not depart from the spirit and scope of the invention.

[0040] Please see Figures 1-3 In this embodiment of the invention, a novel flat wire stator torsion device with automatic chip removal includes a housing 1. A machine platform 2 is fixed on the top of the housing 1. A torsion mechanism 3 is provided on the machine platform 2. A drive mechanism 6 is provided inside the housing 1 on one side corresponding to the torsion mechanism 3. The drive mechanism 6 is used to drive the torsion mechanism 3 to rotate and synchronously drive the torsion mechanism 3 to move upward during the rotation. When the drive mechanism 6 drives the torsion mechanism 3 to move downward, the torsion mechanism 3 will not rotate. A dust suction pipe 5 is fixed on one side of the rear of the machine platform 2. A suction pump 4 is installed on the dust suction pipe 5. The suction pump 4 cooperates with the dust suction pipe 5 to suck out the debris generated during the torsion of the flat wire.

[0041] Please see Figures 4-5The top of the machine base 2 is provided with a circular groove 21, and the torsion mechanism 3 is movably arranged in the circular groove 21. One end of the suction pipe 5 penetrates the inner wall of the machine base 2 and extends into the circular groove 21. The torsion mechanism 3 includes a bearing plate 31, an outer torsion plate 32 and an inner torsion plate 33. The bearing plate 31, the outer torsion plate 32 and the inner torsion plate 33 are all circular bowl-shaped structures and are arranged to rotate concentrically. The outer torsion plate 32 is rotatably sleeved on the outside of the inner torsion plate 33, and the bearing plate 31 is rotatably sleeved on the outside of the outer torsion plate 32.

[0042] Multiple vertically penetrating torsion grooves 36 are equally spaced around the edges of the outer torsion disc 32 and the inner torsion disc 33, and the torsion grooves 36 on the outer torsion disc 32 correspond one-to-one with the torsion grooves 36 on the inner torsion disc 33. The torsion grooves 36 are used to insert and position the flat wire of the flat wire stator to be torsion. The bearing disc 31 is provided with a bearing groove 34 inside. The outer torsion disc 32 and the inner torsion disc 33 are rotatably connected in the bearing groove 34. The bottom inner wall of the bearing groove 34 is provided with a vertically penetrating through hole 35 on one side corresponding to the multiple torsion grooves 36. During the torsion process, the insulating varnish debris generated in the torsion groove 36 falls into the circular groove 21 through the corresponding through hole 35. Then, through the cooperation of the dust suction pipe 5 and the suction pump 4, the debris in the circular groove 21 is sucked out.

[0043] The outer torsion disc 32 has a first gear set 37 at the center of the top of the disc surface, the inner torsion disc 33 has a second gear set 38 at the center of the top of the disc surface, the inner torsion disc 33 has a groove 39 on the bottom side corresponding to the first gear set 37, and the bearing disc 31 has a mounting base 310 at the center of the bottom.

[0044] In this embodiment, two torsion discs, one inside and one outside, are used as an example. In actual applications, the number of torsion discs corresponds one-to-one with the number of flat wire layers. Multiple torsion discs are set to rotate concentrically, and two adjacent torsion discs can rotate independently. The multiple layers of flat wire are inserted into the torsion grooves 36 of the multiple torsion discs one by one in the order from the outside to the inside. The flat wire is twisted by rotating the torsion discs. In order to ensure that multiple torsion discs can rotate independently, corresponding gear sets need to be set. Taking four torsion discs as an example, the gear set structure of the outermost torsion disc (i.e., outer torsion disc 32) and the torsion disc in the third layer (not shown in the figure) can adopt the gear structure in the first gear set 37 or other similar transmission structures. The gear set structure of the torsion disc in the second layer (i.e., inner torsion disc 33) and the torsion disc in the fourth layer (not shown in the figure) can adopt the gear structure in the second gear set 38 or other similar transmission structures. The selection of gear sets needs to ensure that two adjacent torsion discs can rotate synchronously in opposite directions.

[0045] Please see Figures 6-7The first gear set 37 includes a first internal gear 371, a first external gear ring 372, and a first sealing cover 373. The first internal gear 371 is rotatably connected to the center of the top of the outer torsion disk 32. The first external gear ring 372 is meshed and sleeved on the outside of the first internal gear 371 and is fixed on the outer torsion disk 32. The first sealing cover 373 is snapped and fixed on the outside of the first external gear ring 372 and is rotatably embedded in the groove 39. The first sealing cover 373 encapsulates the first internal gear 371 and the first external gear ring 372.

[0046] The second gear set 38 includes a second internal gear 381, a transmission gear 382, ​​a second external gear ring 383, and a second sealing cover 384. The second internal gear 381 is rotatably connected to the center of the top of the inner torsion disk 33. The transmission gear 382 meshes with the second internal gear 381 and is rotatably connected to one side of the top of the inner torsion disk 33. The second external gear ring 383 is sleeved on the outside of the second internal gear 381 and the transmission gear 382 and meshes with the transmission gear 382. The second external gear ring 383 is fixed at the center of the top of the inner torsion disk 33. The second external gear ring 383 does not contact the second internal gear 381 and there is a gap between them. The second sealing cover 384 is snapped and fixed to the outside of the second external gear ring 383, thus encapsulating the second external gear ring 383 and its internal gear transmission structure.

[0047] Please see Figures 8-9 Multiple rollers 362 are rotatably connected from top to bottom on both the left and right side walls of the torsion groove 36. Multiple air nozzles 361 are fixed from top to bottom on both the front and rear side walls of the torsion groove 36. The air outlets of the multiple air nozzles 361 on the front and rear sides are inclined downwards towards the central axis of the torsion groove 36. The multiple air nozzles 361 on the front and rear sides are connected by pipes to form two sets of air jet structures. Both sets of air jet structures are connected to an external air pump through pipes.

[0048] In this embodiment, when the flat wire is twisted in the twisting groove 36, the flat wire will rub against the left and right side walls of the twisting groove 36. At this time, the rollers 362 can convert the original sliding friction into rolling friction, reducing the damage to the outer insulating varnish of the flat wire and protecting the flat wire. During one twisting process, insulating varnish debris will inevitably be generated in the twisting groove 36. At this time, multiple air nozzles 361 on the front and rear sides of the twisting groove 36 blow air downwards into the groove, blowing the varnish debris attached to the groove downwards. The debris falls into the circular groove 21 through the opening at the bottom of the twisting groove 36 and the corresponding through hole 35. Then, the varnish debris is sucked out by the combined use of the suction pipe 5 and the suction pump 4, thereby ensuring that the twisting groove 36 is clean and tidy, and easy to twist and use again.

The transmission rod 66 is rotatably connected to the inner wall of the outer torsion plate 32 and the inner wall of the inner torsion plate 33. The transmission rod 66 can only rotate with the outer torsion plate 32 and the inner torsion plate 33. When the transmission rod 66 moves upward, the outer torsion plate 32 and the inner torsion plate 33 move upward synchronously.

[0051] The first internal gear 371 and the second internal gear 381 are both sleeved and fixed on the transmission rod 66. When the transmission rod 66 rotates, the first internal gear 371 and the second internal gear 381 will rotate synchronously.

Through the cooperation of the guide bars 629 and the guide grooves 630, the transmission rod 66 can slide more smoothly up and down. At the same time, when the slide cylinder 610 rotates, it can drive the transmission rod 66 to rotate synchronously.

[0056] In this embodiment, in the initial stage (that is, the flat wire is placed into the torsion groove 36, but has not yet started to twist), the slide plate 63 is located at the lower end inside the groove 62, and at this time the slide plate 63 is exactly at its limit position (lowest point) where it can move downwards. At this time, the starting point of the driving half gear 612 (that is, the first tooth, see Appendix) is... Figure 13Just as it begins to contact the driven gear 68, but before meshing and transmission begins, the dual-axis synchronous motor 619 starts running, driving the drive disk 618 to rotate. In the initial stage, the second link 627 is also at the lowest point. As the drive disk 618 rotates continuously, it will drive the second link 627 to gradually move upward. The linkage plate 624 and the first link 626 connected to the second link 627 will also move upward synchronously. The first link 626 is rotatably connected to the slide plate 63. When the first link 626 moves upward, it will drive the slide plate 63 to move upward 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 bearing disk 31 connected to it upward, so that the bearing disk 31 and its internal torsion disk move upward axially. Without the need to set up an additional Z-axis motion platform, it can achieve a similar effect of synchronous movement of the Z-axis during the torsion process.

[0057] As the dual-shaft synchronous motor 619 continues to operate, its other end, the drive shaft 620, connected via belt 617 and pulley 616, rotates continuously. The drive shaft 620 drives the rotating shaft 611 and its driving half-gear 612 via a bevel gear structure. As the driving half-gear 612 rotates, it gradually meshes with the driven gear 68 and begins to transmit power, causing the driven gear 68 to rotate. The driven gear 68 is fitted and fixed onto the slide cylinder 610. When the driven gear 68 rotates, the slide cylinder 610 moves synchronously forward. The transmission rod 66 is slidably connected in the slide cylinder 610. When the slide cylinder 610 rotates, it will drive the transmission rod 66 to rotate synchronously. The first internal gear 371 and the second internal gear 381 fixed at the top of the transmission rod 66 will rotate synchronously with the transmission rod 66. When the first internal gear 371 and the second internal gear 381 rotate, they will drive the corresponding first external gear ring 372 and the second external gear ring 383 to rotate synchronously, which will in turn drive the corresponding torsion disk to rotate synchronously in the opposite direction. At this time, the flat wire located in the torsion groove 36 will be torsionally deformed as the torsion disk rotates.

[0058] When the drive disc 618 rotates half a turn, the second connecting rod 627 also moves from the bottom of one side of the disc to the top of the other side of the disc. At this time, the slide plate 63 also moves up to its maximum height (highest point). Simultaneously, the drive half gear 612, which operates synchronously with the drive disc 618, also rotates half a turn. At this time, the end point of the drive half gear 612 (that is, the last tooth, see appendix) Figure 13Just as it disengages from the driven gear 68, the driving half gear 612 and the driven gear 68 no longer mesh. Then the drive disk 618 continues to rotate, causing the second connecting rod 627 to gradually move downward. Other structures connected to the second connecting rod 627 move downward synchronously, eventually causing the transmission rod 66 to move downward synchronously. During the downward movement of the transmission rod 66, since the driving half gear 612 does not mesh 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. Therefore, the twisted flat wire will not be subjected to a reverse torsional force, and the twisted flat wire can be vertically detached from the torsion groove 36, perfectly maintaining the shape of the twisted flat wire. By replacing the traditional industrial control software with a mechanical transmission structure, the torsion disk can rotate and move axially at the same time. 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 movements can maintain a stable synchronous relationship. Compared with setting an independently operating Z-axis motion platform, this mechanical structure is less prone to errors, and the torsion processing effect is also better.

[0059] When torsion processing is required for flat wire stators of different specifications, the pin heights at the stator ends vary. In this case, the positioning seat 625 can be moved to adjust the vertical movement distance of the second connecting rod 627. The closer the second connecting rod 627 is to the center of the drive disc 618, the shorter its vertical movement distance; the farther apart the second connecting rod 627 is from the center of the drive disc 618, the longer its vertical movement distance. By changing the displacement distance of the second connecting rod 627, the maximum vertical sliding distance of the transmission rod 66 is adjusted. Consequently, the maximum axial movement distance of the torsion disc connected to the transmission rod 66 also changes accordingly. A larger pin height results in a longer axial movement distance for the torsion disc, while a smaller pin height results in a shorter axial movement distance. This allows the torsion disc to adapt to the torsion processing needs of flat wire stators with different pin heights, making it more convenient to use. The device is more adaptable, does not require a dedicated machine, and saves costs.
