[0051] Figure 1 The structure diagram of the flat wire stator is shown. The flat wire 12 of the stator 10 has completed the twisting operation. The flat wire stator includes a core 11 and a flat wire 12. The core 11 has a slot for inserting the flat wire 12. The number of slots is between 200 and 300. Each slot can insert multiple layers of flat wires 12, such as 6 layers, 8 layers or 10 layers. The flat wire 12 is generally a copper wire.

[0052] Figure 2 The structure diagram of the twisting machine for flat wire motor in the embodiment of the present application is shown. The twisting machine for flat wire motor includes a frame 100, a material taking mechanism 200, a first wire clamping mechanism 300, a second wire clamping mechanism 400 and a twisting device 20.

[0053] Figure 3 The structure diagram of the twisting machine for flat wire motor in the embodiment of the present application is shown. The twisting machine for flat wire motor includes a frame 100, a material taking mechanism 200, a first wire clamping mechanism 300, a second wire clamping mechanism 400 and a twisting device 20. Figure 2Fig. 2 is a schematic diagram of the working of the taking mechanism 200 of the head twisting machine in Fig. 1. The taking mechanism 200 is installed on the frame 100, and is used to carry the stator 10 from the outside, such as a flow line, to the first through hole 311 of the first wire clamping mechanism 300.

[0054] Specifically, in combination with Figure 3 , the taking mechanism 200 comprises a clamping clamp 210, a first lifting driving member 220, a first horizontal sliding driving member 230, and a taking bracket 240. The clamping clamp 210 is used to clamp the core 11 of the stator 10, and is installed on the first lifting driving member 220. The first lifting driving member 220 is slidably installed on the taking bracket 240 along a first direction. The first horizontal sliding driving member 230 is installed on the taking bracket 240 and is used to drive the first lifting driving member 220 to slide along the first direction. The taking bracket 240 is installed on the frame 100. In this way, the clamping clamp 210 can realize lifting movement through the first lifting driving member 220 and realize sliding along the first direction through the first horizontal sliding driving member 230.

[0055] Referring to Figure 2 , the taking mechanism 200 and the second wire clamping mechanism 400 are sequentially distributed along the first direction, which facilitates continuous operation and avoids transfer, and the layout is reasonable. The taking mechanism 200 is located above the first wire clamping mechanism 300. In this way, the taking mechanism 200 takes and places the stator 10 through the clamping clamp 210, moves the stator 10 from the outside to above the first wire clamping mechanism 300 through the first horizontal sliding driving member 230, and places the stator 10 into the first through hole 311 of the first wire clamping mechanism 300 through the first lifting driving member 220.

[0056] Figure 4 Fig. 4 is a schematic diagram of the structure of the first wire clamping mechanism 300 and the second wire clamping mechanism 400 installed on the frame 100 in the embodiment. Figure 5 Fig. 5 is a schematic diagram of the structure of the first wire clamping mechanism 300 in Fig. 4. Figure 4 Fig. 6 is a schematic diagram of the structure of the second wire clamping mechanism 400 in Fig. 4. Figure 6 Fig. 7 is a schematic diagram of the structure of the second wire clamping mechanism 400 in Fig. 4. Figure 5An exploded view of the first wire clamping mechanism 300. The first wire clamping mechanism 300 includes a mounting base 310, straightening clamps 320, a wire clamping turntable 330, and a first rotary drive 340. The mounting base 310 is mounted on the frame 100 and has a first through hole 311 and a plurality of sliding grooves 312 distributed circumferentially along the first through hole 311. The first through hole 311 is used to accommodate the stator 10. The number of straightening clamps 320 is the same as the number of sliding grooves 312. The straightening clamps 320 are slidably mounted in the sliding grooves 312. The wire clamping turntable 330 is rotatably mounted on the mounting base 310 and is connected to the straightening clamps 320. The first rotary drive 340 is used to drive the wire clamping turntable 330 to rotate. The straightening clamps 320 slide into the first through hole 311 and clamp the flat wire 12 of the stator 10 as the wire clamping turntable 330 rotates. When the straightening clamp 320 slides into the first through hole 311, two adjacent straightening clamps 320 can clamp the flat wire 12 of the stator 10 located in the first through hole 311. When the straightening clamp 320 slides away from the first through hole 311, the two adjacent straightening clamps 320 release the flat wire 12.

[0057] Optionally, the number of sliding grooves 312 is 200 to 300, the top of the sliding grooves 312 is open, and the sliding grooves 312 extend straight along the radial direction of the mounting base 310.

[0058] Optionally, as the sliding groove 312 extends circumferentially along the wire clamping turntable 330, its radius gradually changes, causing the wire clamping turntable 330 to rotate. The straightening clamp 320 slides along the guide groove 331, and its radial distance along the first through hole 311 gradually changes, allowing it to slide within the sliding groove 312. For example, if the wire clamping turntable 330 rotates clockwise, the straightening clamp 320 slides within the sliding groove 312 in a direction away from the first through hole 311 to release the flat wire 12. If the wire clamping turntable 330 rotates counterclockwise, the straightening clamp 320 slides within the sliding groove 312 in a direction closer to the first through hole 311 to clamp the flat wire 12.

[0059] Specifically, the first wire clamping mechanism 300 also includes a first engaging member 350, which is connected to the wire clamping turntable 330. The output shaft of the first rotary drive member 340 is connected to a second engaging member 360 that engages with the first engaging member 350, thereby driving the wire clamping turntable 330 to rotate through the first engaging member 350 and the second engaging member 360.

[0060] Specifically, the first thread clamping mechanism 300 further comprises a protection box 370, the first engaging member 350 is located in the protection box 370, the protection box 370 has a mounting hole for the output shaft of the first rotating driving member 340 to enter the protection box 370, and the protection box 370 has a fourth notch 371 on the side close to the first engaging member 350, so that the first engaging member 350 is engaged with the second engaging member 360 through the first engaging member 350. The arrangement of the protection box 370 can ensure that the first rotating driving member 340 and the first engaging member 350 are stably engaged, and external interference is avoided.

[0061] In some embodiments, the first thread clamping mechanism 300 further comprises a limiting ring 380, which is located on the side of the straightening clamp 320 away from the bottom of the sliding groove 312, so that the straightening clamp 320 is limitedly installed in the sliding groove 312, and the straightening clamp 320 is prevented from being buckled and separated from the sliding groove 312.

[0062] In some embodiments, the first thread clamping mechanism 300 further comprises a cover plate 390, which is installed on the mounting seat 310, and the cover plate 390 has a fourth through hole 391 corresponding in position to the first through hole 311, so that the stator 10 is exposed above the first thread clamping mechanism 300 and clamped by the second thread clamping mechanism 400 to fix one end of the flat wire 12. The cover plate 390 is located on the side of the thread clamping turntable 330 away from the straightening clamp 320, so as to cover the thread clamping turntable 330 and ensure that the movement process of the thread clamping turntable 330 and the straightening clamp 320 is not disturbed by the outside world.

[0063] Specifically, the mounting seat 310 and the thread clamping turntable 330 are coaxially arranged.

[0064] Figure 7The structure diagram of the straightening clamp 320 of the first wire clamping mechanism 300. The straightening clamp 320 comprises a connecting rod 321 and a clamp 322. The connecting rod 321 is connected to the clamp 322, and the clamp 322 is slidingly installed in the sliding groove 312 one by one. When the clamp 322 slidingly extends into the through hole, the adjacent two clamps 322 can clamp the flat wire 12. The wire clamping turntable 330 has a guide groove 331 corresponding to the connecting rod 321, and the connecting rod 321 extends into the guide groove 331. The first rotary driving member 340 drives the wire clamping turntable 330 to rotate, the connecting rod 321 slides in the guide groove 331, and the clamp 322 slides in the sliding groove 312, so that the clamp 322 enters and exits the first through hole 311. When the clamp 322 slidingly extends into the first through hole 311, the adjacent two clamps 322 can clamp the flat wire 12 of the stator 10, and the flat wire 12 is clamped and straightened. At this time, the second wire clamping mechanism 400 clamps the other end of the flat wire 12 and moves away from the first wire clamping mechanism 300. The clamp 322 opens and closes at a certain frequency to gradually straighten the flat wire 12, or the clamp 322 keeps the clamping state to gradually straighten the flat wire 12, so that the straightened flat wire 12 is smoothly inserted into the wire slot 621 of the head twisting device 20 in the subsequent head twisting action.

[0065] Specifically, referring to Figure 4 , the head twisting machine further comprises a sliding plate 510 and a second horizontal sliding driving member 520. The mounting seat 310 is installed on the sliding plate 510, the sliding plate 510 is slidingly installed on the rack 100 in the first direction, the sliding plate 510 is located between the first wire clamping mechanism 300 and the head twisting device 20, and the sliding plate 510 has a second through hole for accommodating the stator 10. The second horizontal sliding driving member 520 is installed on the rack 100, and the second horizontal sliding driving member 520 is used to drive the sliding plate 510 to slide in the first direction, so that the first wire clamping mechanism 300 is aligned with the second wire clamping mechanism 400 or the head twisting device 20.

[0066] Please continue to refer to Figure 4 , the head twisting machine further comprises a detection switch 530. The detection switch 530 is installed on the sliding plate 510, and the detection switch 530 is used to detect whether the stator 10 exists in the first through hole 311. When the detection switch 530 detects that the stator 10 is placed in the first through hole 311, the first rotary driving member 340 is started to straighten the flat wire 12. At the same time, the second wire clamping mechanism 400 is started to clamp the upper end of the flat wire 12 and move the stator 10 upwards, so that the straightening clamp 320 can gradually straighten the flat wire 12.

[0067] Please refer to Figure 4 , the second wire clamping mechanism 400 is installed on the rack 100 and located above the first wire clamping mechanism 300. The second wire clamping mechanism 400 can clamp the flat wire 12 to move away from the first wire clamping mechanism 300.

[0068] Specifically, the second wire clamping mechanism 400 is mounted on the frame 100 via the upper wire clamping bracket 550, thereby being positioned above the first wire clamping mechanism 300. Simultaneously, the second wire clamping mechanism 400 is vertically and flexibly mounted on the upper wire clamping bracket 550 via a third lifting drive component 540.

[0069] Optionally, the second wire clamping mechanism 400 and the first wire clamping mechanism 300 have the same or substantially the same structure.

[0070] Figure 8 This is a schematic diagram of the head-turning device 20 of the head-turning machine in this embodiment. Please refer to... Figure 2 and Figure 8 The twisting device 20 is installed on the frame 100 and located below the first wire clamping mechanism 300. The twisting device 20 is used to twist the lower end of the flat wire 12 clamped in the first wire clamping mechanism 300.

[0071] Specifically, the twisting device 20 includes a flat wire twisting mechanism 600 and a twisting drive mechanism 700.

[0072] Figure 9 for Figure 8 A schematic diagram of the flat wire twisting mechanism 600 of the twisting device 20. Figure 10 for Figure 9 A top view of the flat wire twisting mechanism 600. Figure 11 for Figure 9 A cross-sectional view of the flat wire twisting mechanism 600. The flat wire twisting mechanism 600 includes a support shaft 611 and a twisting wire reel 620. There are multiple twisting wire reels 620, which are rotatably mounted on the top of the support shaft 611 in a radial direction. The top of the twisting wire reel 620 has multiple wire grooves 621 distributed circumferentially along the twisting wire reel 620. The wire grooves 621 are used to accommodate flat wire 12.

[0073] Figure 13 for Figure 8 A schematic diagram of the torsion drive mechanism 700 of the torsion device 20. Figure 14 for Figure 13 Enlarged view at point A in the figure. The twisting drive mechanism 700 includes a support base 710, a second rotary drive member 720, and a second lifting drive member 730. The middle part of the support base 710 is used to place the flat wire twisting mechanism 600. The support base 710 is connected to the bottom of the support shaft 611. There are multiple second rotary drive members 720, each corresponding to a twisting wire reel 620. Multiple second rotary drive members 720 are sequentially installed on the support base 710 around the circumference of the flat wire twisting mechanism 600. Each second rotary drive member 720 is connected to the corresponding twisting wire reel 620 to drive the corresponding twisting wire reel 620 to rotate. The second lifting drive member 730 is used to drive the support base 710 to lift.

[0074] Thus, the second lifting driving member 730 works, the head-twisting disc 620 moves upward, the flat wire 12 of the first wire clamping mechanism 300 is loaded into the wire slot 621, the second rotating driving member 720 works to drive the head-twisting disc 620 to rotate to twist the head of the flat wire 12. The head-twisting disc 620 moves upward and rotates at the same time to complete the head-twisting operation.

[0075] Please refer to Figure 9 to Figure 11 , the flat wire head-twisting mechanism 600 further comprises an adapter sleeve 631 and a transmission disc 640. The number of the head-twisting disc 620, the adapter sleeve 631 and the transmission disc 640 is multiple and one-to-one correspondence. The number of the head-twisting disc 620 is greater than or equal to the number of layers of the flat wire 12 of the stator 10. For example, the number of the head-twisting disc 620, the adapter sleeve 631 and the transmission disc 640 is six, eight or ten. The multiple adapter sleeves 631 are sequentially and rotatably sleeved on the middle part of the support shaft 611 along the radial direction of the support shaft 611, the top of the adapter sleeve 631 is connected with the corresponding head-twisting disc 620, and the multiple transmission discs 640 are sequentially and rotatably sleeved on the support shaft 611 from bottom to top, each transmission disc 640 is connected with the bottom of the corresponding adapter sleeve 631, and each second rotating driving member 720 is connected with the corresponding transmission disc 640 of the head-twisting disc 620.
