They are only for convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0055] During the production process of the coil winding of the flat wire motor, in order to improve the production efficiency, a continuous winding technology for the wire group is developed to achieve the one-time winding production of the coil winding. The coil winding includes a plurality of coils. The plurality of coils are wound from the same wire. The plurality of coils are arranged at circumferential intervals. The vertical heights of the plurality of coils decrease or increase in sequence. A crossover wire is connected between two adjacent coils. After the winding of the coil winding is completed, in order to perform the subsequent assembly of the coil winding, it is necessary to shape all the coils in the coil winding to the same horizontal plane and contract all the coils into a circular shape. Therefore, it is necessary to drive each coil in the three degrees of freedom directions in space to achieve the shaping of the coil winding.

[0056] As Figures 1 to 6 shown, this embodiment provides a coil winding shaping device to achieve the shaping of all the coils 2000 in the coil winding. The coil winding shaping device includes a multi-stage driving assembly 100 connected in sequence. Among them, the connection order of the multi-stage driving assembly 100 is the same as the connection order of the plurality of coils 2000. The output end of each stage of the driving assembly 100 can place a coil 2000. The output end of each stage of the driving assembly 100 except the driving assembly 100 at the end in the multi-stage driving assembly 100 is connected to the next stage of the driving assembly 100. Each stage of the driving assembly 100 except the driving assembly 100 at the end in the multi-stage driving assembly 100 can drive the corresponding coil 2000 and the next stage of the driving assembly 100 to move along a preset trajectory. The driving assembly 100 at the end in the multi-stage driving assembly 100 can drive the corresponding coil 2000 to move along a preset trajectory, so that the corresponding coil 2000 is flush with the coil 2000 on the previous stage of the driving assembly 100 in the vertical direction and deflects a preset angle around a preset axis in the horizontal direction.

[0057] This coil winding shaping device is equipped with a multi-stage driving component 100 connected in sequence. The output end of each driving component 100 except the one at the end is connected to the next-level driving component 100. A coil 2000 is placed at the output end of each driving component 100, and it is ensured that the connection sequence of the multi-stage driving components 100 is the same as the connection sequence of the multiple coils 2000. Each driving component 100 except the one at the end drives the corresponding coil 2000 and the next-level driving component 100 to move along a preset trajectory, and the driving component 100 at the end drives the corresponding coil 2000 to move along a preset trajectory, so that the coil 2000 corresponding to each driving component 100 is flush with the coil 2000 on the previous-level driving component 100 in the vertical direction and deflects a preset angle around a preset axis in the horizontal direction. It can achieve that all the coils 2000 in the coil winding are flush with each other in the vertical direction and adjacent two coils 2000 deflect a preset angle around a preset axis in the horizontal direction, and further achieve the effect that all the coils 2000 are distributed in a horizontal circular pattern around the preset axis, completing the shaping of the coil winding with good shaping effect and high shaping efficiency.

[0058] Specifically, when shaping the coil winding, the second-level driving component 100 in the multi-stage driving mechanism 100 drives the corresponding coil 2000 to move until the coil 2000 corresponding to the second-level driving component 100 is flush with the coil 2000 corresponding to the first-level driving component 100 in the vertical direction and deflects a preset angle around a preset axis in the horizontal direction. Subsequently, the third-level driving component 100 drives the corresponding coil 2000 to move until the coil 2000 corresponding to the third-level driving component 100 is flush with the coil 2000 corresponding to the second-level driving component 100 in the vertical direction and deflects a preset angle around a preset axis in the horizontal direction. Since the output end of the second-level driving component 100 is connected to the third driving component 100, the third-level driving component 100 will also move under the drive of the second-level driving component 100, so that the coil 2000 corresponding to the third-level driving component 100 is flush with the coil 2000 corresponding to the first-level driving component 100 in the vertical direction and deflects twice the preset angle around a preset axis in the horizontal direction. The fourth-level driving component 100, the fifth-level driving component 100, and the sixth-level driving component 100 and so on, until all the coils in the coil winding are flush with each other in the vertical direction, and adjacent two coils deflect a preset angle around a preset axis in the horizontal direction, making all the coils 2000 distributed in a horizontal circular pattern around the preset axis, completing the shaping of the coil winding with high shaping efficiency and good shaping effect.

[0059] It should be noted that in this embodiment, the coil winding has a total of 8 coils 2000 connected in sequence. When the coil winding is shaped, the eight coils together form a circle, and the adjacent two coils are deflected 45° around the center of the circle. In other embodiments, the specific number of coils in the coil winding can also be adjusted according to actual needs. At this time, only the number of the driving components 100 needs to be adjusted adaptively.

[0060] In addition, in this embodiment, considering the installation space, the multi-stage driving components 100 in the coil winding shaping device are split into two parts. Moreover, the eight coils 2000 are divided into two groups. The four coils 2000 located at both ends of the eight coils 2000 are taken as the first group, and the four coils 2000 located in the central part of the eight coils 2000 are taken as the second group. The multi-stage driving components 100 of the first part are used to shape the coils 2000 of the first group, and the multi-stage driving components 100 of the second part are used to shape the coils 2000 of the second group, so as to reduce the number of stages of the multi-stage driving components 100, thereby simplifying the structure of the multi-stage driving components 100 and reducing the size specification of the multi-stage driving components 100.

[0061] Specifically, as Figures 1 to 6 shown, the coil winding shaping device further includes a frame 600. Among them, the frame 600 has a first working station and a second working station. The first working station and the second working station are both provided with a supporting seat 610. The first working station is used for the multi-stage driving components 100 of the first part to shape the coils 2000 of the first group, and the supporting seat 610 at the first working station is used to support the coils 2000 of the second group. The second working station is used for the multi-stage driving components 100 of the second part to shape the coils 2000 of the second group, and the supporting seat 610 at the second working station is used to support any one of the coils 2000 of the second group.

[0062] In addition, the preset trajectories of each stage of the driving components 100 (except the driving components 100 at the end) in the multi-stage driving components 100 for driving the corresponding coils 2000 and the next-stage driving components 100 to move and the preset trajectory of the driving components 100 at the end of the multi-stage driving components 100 for driving the corresponding coils 2000 to move are all determined according to the shape required after the final shaping of the coil winding. In practical applications, the actual preset trajectory can be determined according to the shaping shape required by the coil winding.

[0063] In this embodiment, each stage of the driving component 100 includes a driving member 110 and a mounting member 120. Among them, the coil 2000 and the corresponding next-stage driving component 100 are both mounted on the mounting member 120. The mounting member 120 is connected to the output end of the driving member 110. The driving member 110 in the first-stage driving component 100 of the multi-stage driving component 100 is movably mounted on the frame 600, and the driving member 110 can drive the mounting member 120 to move. By mounting the coil 2000 and the corresponding next-stage driving component on the mounting member 120, and connecting the mounting member 120 to the output end of the driving member 110, the driving member 110 drives the mounting member 120 to move, so as to achieve the effect of driving the corresponding coil 2000 to move along a preset trajectory. It should be noted that in this embodiment, the driving member 110 is a linear cylinder. The linear cylinder has a simple structure, is convenient for disassembly and assembly, and is sensitive in response. In other embodiments, the driving member 110 can also be a linear motor, a lead screw nut structure or other linear driving structures, which are not specifically limited in this embodiment.

[0064] In addition, to ensure the driving accuracy of the driving member 110, it is necessary to adjust the driving direction of the driving member 110 with respect to the mounting member 120 according to actual needs, so that the driving member 110 can drive the corresponding coil 2000 to move to be flush with the coil 2000 corresponding to the previous-stage driving component 100 in the vertical direction and deflect a preset angle around a preset axis in the horizontal direction.

[0065] As an optional solution, the coil winding shaping device further includes a positioning fixture 200. Among them, a positioning fixture 200 is provided on the mounting member 120 of each driving component 100, and the positioning fixture 200 is used to position and fix the coil 2000. By providing a positioning fixture 200 on the mounting member 120 of each driving component 100 and clamping and fixing the corresponding coil 2000 by the positioning fixture 200, the stable positioning of the coil 2000 can be ensured, and the movement of the coil 2000 relative to the mounting member 120 during the shaping process can be avoided, improving the shaping effect of the coil winding.

[0066] Combined with Figure 7 The specific structure of the positioning fixture 200 will be described. The positioning fixture 200 includes a first clamping member 210 and a second clamping member 220. Among them, the first clamping member 210 and the second clamping member 220 are oppositely arranged in the vertical direction. The first clamping member 210 and the second clamping member 220 are both fixed on the mounting member 120 in the driving component 100, and the coil 2000 is clamped between the first clamping member 210 and the second clamping member 220. By fixing the oppositely arranged first clamping member 210 and second clamping member 220 on the mounting member 120 and clamping and fixing the coil 2000 between the first clamping member 210 and the second clamping member 220, the positioning and fixing of the coil 2000 can be realized, with a simple structure and good fixing effect.

[0067] To further improve the positioning and fixing effect on the coil 2000, a first positioning portion 211 is provided on the end surface of the first clamping member 210 close to the second clamping member 220. The first positioning portion 211 extends towards the second clamping member 220. The first positioning portion 211 is configured to extend into the central cavity of the coil 2000. And a second positioning portion 221 is provided on the end surface of the second clamping member 220 close to the first clamping member 210. The second positioning portion 221 extends towards the first clamping member 210. The second positioning portion 221 is configured to extend into the central cavity of the coil 2000. By providing the first positioning portion 211 extending towards the second clamping member 220 on the end surface of the first clamping member 210 close to the second clamping member 220, and providing the second positioning portion 221 extending towards the first clamping member 210 on the end surface of the second clamping member 220 close to the first clamping member 210, so that both the first positioning portion 211 and the second positioning portion 221 extend into the central cavity of the coil 2000, the positioning of the coil 2000 relative to the first clamping member 210 and the second clamping member 220 can be realized, with a simple structure and a good positioning effect.

[0068] In addition, both the first positioning portion 211 and the second positioning portion 221 are adapted to the central cavity of the coil 2000 to further improve the positioning accuracy of the coil 2000. It should be noted that in this embodiment, the cross-section of the central cavity of the coil 2000 is fan-shaped. Therefore, the cross-sections of both the first positioning portion 211 and the second positioning portion 221 are fan-shaped adapted to the central cavity of the coil 2000. In other embodiments, the cross-sectional shape of the central cavity of the coil 2000 can be arbitrarily adjusted, and the cross-sectional shapes of the first positioning portion 211 and the second positioning portion 221 can be adaptively adjusted. This embodiment does not make specific limitations.

[0069] In other embodiments, the first positioning portion 211 can also be provided only on the first clamping member 210, or the second positioning portion 221 can be provided only on the second clamping member 220. This embodiment does not make specific limitations.

[0070] To further improve the positioning effect of the coil 2000, in this embodiment, a first limiting portion 212 is provided on the end surface of the first clamping member 210 close to the second clamping member 220. The first limiting portion 212 extends towards the second clamping member 220. The first limiting portion 212 is configured to abut against the outer peripheral wall of the coil 2000. And a second limiting portion 222 is provided on the end surface of the second clamping member 220 close to the first clamping member 210. The second limiting portion 222 extends towards the first clamping member 210. The second limiting portion 222 is configured to abut against the outer peripheral wall of the coil 2000. By providing the first limiting portion 212 extending towards the second clamping member 220 on the end surface of the first clamping member 210 close to the second clamping member 220, and providing the second limiting portion 222 extending towards the first clamping member 210 on the second clamping member 220 close to the first clamping member 210, so that the first limiting portion 212 and the second limiting portion 222 respectively abut against the outer peripheral wall of the coil 2000, the relative fixation of the coil 2000 with respect to the first clamping member 210 and the second clamping member 220 can be achieved.

[0071] To further improve the fixing effect of the coil 2000, the first limiting portion 212 and the second limiting portion 222 are respectively provided at both ends of the coil 2000 in the horizontal direction. By respectively providing the first limiting portion 212 and the second limiting portion 222 at both ends of the coil 2000 in the horizontal direction, when the first clamping member 210 and the second clamping member 220 clamp and fix the coil 2000 from the vertical direction, the first limiting portion 212 and the second limiting portion 222 can respectively abut against the outer peripheral wall of the coil 2000 from both ends of the coil 2000 in the horizontal direction.

[0072] In other embodiments, the first limiting portion 212 may also be provided only on the first clamping member 210, or the second limiting portion 222 may be provided only on the second clamping member 220. This embodiment does not make specific limitations.

[0073] During the process of winding a coil winding with a single wire, a tail wire will remain at the end of the coil winding. During the subsequent assembly process of the coil winding, if the tail wire is not shaped, the tail wire will affect the normal assembly of the coil winding and the stator.

[0074] To shape the tail wire, the coil winding shaping device further includes a tail wire shaping assembly 500. Among them, the tail wire shaping assembly 500 is installed on the frame 600, and the tail wire shaping assembly 500 is configured to shape and position the tail wire of the coil winding.

[0075] Combined with Figures 4 to 6The specific structure of the tail wire shaping assembly 500 will be described. The tail wire shaping assembly 500 includes a support base 540, a moving member 510, a connecting member 520, and a fastening member 530. Among them, the support base 540 is fixed on the frame 600, the moving member 510 is installed on the support base 540, the connecting member 520 is connected to the output end of the moving member 510, the fastening member 530 is fixed on the connecting member 520, and the fastening member 530 is used to clamp and fix the tail wire of the coil winding. The moving member 510 can drive the connecting member 520 to move. By setting the support base 540 on the frame 600, installing the moving member 510 on the support base 540, connecting the connecting member 520 to the output end of the moving member 510, and fixing the fastening member 530 for clamping and fixing the tail wire of the coil winding on the connecting member 520, and using the driving of the moving member 510 on the connecting member 520, the shaping of the tail wire clamped and fixed by the fastening member 530 can be realized. It should be noted that in this embodiment, the moving member 510 is a linear cylinder. The linear cylinder has a simple structure, is convenient for disassembly and assembly, and is sensitive in response. In other embodiments, the moving member 510 can also be a linear motor, a lead screw nut structure, or other linear drive structures, which are not specifically limited in this embodiment.

[0076] As Figure 8 shown, the fastening member 530 includes a first fastening portion 531 and a second fastening portion 532.

[0077] In an alternative embodiment, as Figures 1 to 3As shown in the figure, the coil winding shaping device further includes a commutation component 300. The output end of the commutation component 300 is connected to the first-stage driving component 100 in the multi-stage driving component 100. The first working station of the frame 600 includes a shaping position and a material changing position that are oppositely arranged in the horizontal direction. The shaping position is used for shaping the coil winding, and the material changing position is used for clamping the coil winding. The commutation component 300 is used to drive the entire multi-stage driving component 100 to reciprocate between the shaping position and the material changing position. By setting a shaping position for shaping the coil winding and a material changing position for clamping the coil winding at the first working station of the frame 600, and connecting the output end of the commutation component 300 to the first-stage driving component 100 in the multi-stage driving component 100, the commutation component 300 drives the multi-stage driving component 100 to reciprocate between the shaping position and the material changing position. When it is necessary to clamp the coil winding onto the multi-stage driving component 100, the commutation component 300 drives the multi-stage driving component 100 to move to the material changing position. When it is necessary to shape the clamped coil winding, the commutation component 300 drives the multi-stage driving component 100 to move to the shaping position. When the shaping of the coil winding is completed, the commutation component 300 drives the multi-stage driving component 100 to move to the material changing position to disassemble the shaped coil winding and re-clamp the unshaped coil winding, which can improve the feeding and discharging efficiency of the coil winding.

[0078] It should be noted that in this embodiment, the commutation component 300 includes a linear cylinder. The linear cylinder has a simple structure, is convenient for disassembly and assembly, and has a sensitive reaction. The multi-stage driving component 100 is connected to the output end of the linear cylinder, and the linear cylinder drives the multi-stage driving component 100 to reciprocate between the shaping position and the material changing position. In other embodiments, the commutation component 300 may also include a linear motor, a lead screw nut structure, or other linear driving structures, which are not specifically limited in this embodiment.

[0079] To improve the driving accuracy of the commutation component 300, the coil winding shaping device further includes a guiding component 400. The guiding component 400 includes a guiding slider 410 and a guiding rail 420. The guiding rail 420 is fixed on the frame 600 and extends along a preset direction. The guiding slider 410 is fixed on the multi-stage driving component 100, and the guiding slider 410 is slidably matched with the guiding rail 420. The preset direction is the direction in which the shaping position and the material changing position are oppositely arranged. By setting the guiding rail 420 on the frame 600 to extend along the direction in which the shaping position and the material changing position are oppositely arranged, and setting a guiding slider 410 slidably matched with the guiding rail 420 on the multi-stage driving component 100, when the commutation component 300 drives the multi-stage driving component 100 to move between the shaping position and the material changing position, the guiding slider 410 can slide along the guiding rail 420, thereby ensuring the driving accuracy of the commutation component 300.

[0081] 1) The multi-stage driving component 100 at the first station is moved to the material changing position by the position changing component 300. The unshaped coil winding is clamped on the multi-stage driving component 100, and the tail wire of the coil winding is clamped on the tail wire shaping component 500;

[0082] 2) The multi-stage driving component 100 at the first station is moved to the shaping position by the position changing component 300. Subsequently, the multi-stage driving component 100 at the first station drives the corresponding coil 2000 to move respectively to shape the first group of coils 2000 in the coil winding. The moving part 510 in the tail wire shaping component 500 drives the tail wire to move to shape the tail wire;

[0083] 3) The multi-stage driving component 100 at the first station is moved to the material changing position by the position changing component 300. The coil winding after shaping the first group of coils 2000 in the coil winding is moved from the multi-stage driving component 100 at the first station to the multi-stage driving component 100 at the second station;

[0084] 4) The multi-stage driving component 100 at the second station drives the corresponding coil 2000 to move respectively to shape the second group of coils 2000 in the coil winding, thereby completing the shaping of the coil winding.
