DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 6 As shown, an embodiment of the present invention provides a stator wire strand cutting device for twisting the lead wires 11 on the stator 1 and cutting off the excess portion of the twisted lead wires 11 during the motor processing process.

[0025] Please refer to Figure 1 and Figure 2The stator wire strand cutting device includes a frame 100, on which a conveyor line 200 and a tray 300 movably arranged on the conveyor line 200 are provided. The conveyor line 200 is used to transport the tray 300 along the length direction of the conveyor line 200. The tray 300 has a supporting surface 301 and the stator 1 to be processed is placed on the supporting surface 301. The frame 100 is also provided with a stranding assembly 400, a shearing assembly 500 and a jacking assembly 600, wherein the stranding assembly 400 includes a stranding seat 401 arranged directly above the conveying line 200, the stranding seat 401 is provided with a rotatable rotating seat 402 and a first driving member connected to the rotating seat 402, the first driving member is used to drive the rotating seat 402 to rotate, and the rotating seat 402 is provided with a clamping jaw 403 and a second driving member connected to the clamping jaw 403, the second driving member is used to drive the clamping jaw 403 to clamp or release; the shearing assembly 500 includes two movable seats 501 movably arranged on the frame 100 and a third driving member 502 connected to the movable seat 501, the two movable seats 501 are respectively located on opposite sides of the clamping jaw 403 and the two The sides of the movable seats 501 that are close to each other are respectively provided with cutters 503, and the third driving member 502 is used to drive the two movable seats 501 to approach or move away from each other, and the cutters 503 on the two movable seats 501 are docked when the two movable seats 501 approach each other; the jacking assembly 600 includes a jacking plate 601 that can be raised and lowered on the frame 100 and a fourth driving member 602 that is transmission-connected to the jacking plate 601, and the jacking plate 601 is located below the pallet 300, and when the fourth driving member 602 drives the jacking plate 601 to rise, the jacking plate 601 abuts against the pallet 300 and drags the pallet 300 to rise so that the pallet 300 is close to the stranded wire assembly 400, so as to move the stator 1 to be processed placed on the pallet 300 to a position close to the stranded wire assembly 400.

[0026] Specifically, the stator wire stranding and cutting device provided in this embodiment performs the following steps on the stator 1 for stranding and cutting: the conveyor line 200 moves the tray 300 on which the stator 1 to be processed is placed to the bottom of the stranding assembly 400; after the tray 300 is moved into position, the fourth driving member 602 drives the lifting plate 601 to rise and pushes the tray 300 to rise until the lead wire 11 of the stator 1 reaches the stranding assembly 400; at this time, the second driving member drives the clamping claw 403 to clamp the lead wire 11 of the stator 1; and then the first driving member drives the rotating seat 402 to rotate so that the lead wire 11 on the stator 1 can be twisted, and the stranding is completed. After completion, the second driving member drives the clamping claw 403 to release the lead wire 11, and then the third driving member 502 drives the two movable seats 501 to approach each other so that the excess part of the twisted lead wire 11 can be cut off by the cutter 503. After the lead wire 11 is cut off, the movable seat 501 is reset under the drive of the third driving member 502, and the lifting plate 601 is reset under the drive of the fourth driving member 602. At this time, the tray 300 descends in the vertical direction and is replaced on the conveyor line 200. The tray 300 can be transported together with the processed stator 1 to the next workstation for further processing through the conveyor line 200. The stator wire twisting and cutting device provided in this embodiment can automatically complete the twisting and cutting operations of the lead wires 11 of the motor stator 1, effectively improving the processing efficiency of the motor stator 1 and reducing the labor intensity of workers. It can also ensure that the number of turns and the tightness of the twisted lead wires 11 remain consistent by controlling the actions of the clamping jaws 403 and the rotating seat 402, thereby ensuring good consistency of the processed products.

[0027] like Figure 2 and Figure 3As shown, in this embodiment, a mounting seat 101 is provided on the frame 100, a slide groove is provided on the mounting seat 101, and the length direction of the slide groove is consistent with the vertical direction, and the stranded wire seat 401 is movably arranged in the slide groove. The mounting base 101 with the sliding groove is provided on the frame 100 for the installation of the stranding seat 401, so that the stranding seat 401 can move in the vertical direction relative to the frame 100. After the clamping jaws 403 clamp the lead wire 11, the rotating seat 402 rotates to strand the wire. As the multiple strands of lead wire 11 are twisted, the lead wire 11 changes from a vertical state to a spiral state, resulting in a gradual reduction in the distance between the position where the lead wire 11 is clamped by the clamping jaws 403 and the stator 1. At this time, as the rotating seat 402 rotates, the stranding seat 401 slides in the sliding groove and approaches the stator 1 to prevent the lead wire 11 from being stretched during the stranding process, causing damage to the lead wire 11 or being pulled out of the stator 1, thereby improving product quality. In this embodiment, the first driving member can be a motor and the second driving member can be a cylinder, so that the clamping jaws 403 can clamp the lead wire 11 while the rotating seat 402 can rotate smoothly.

[0028] In detail, the mounting seat 101 is provided with a first guide rod 102, the axial direction of the first guide rod 102 is consistent with the vertical direction and the wire stranding seat 401 is provided with a first guide hole that cooperates with the first guide rod 102, and the first guide rod 102 is sleeved with two first springs 103 and the two first springs 103 are respectively in one-to-one contact with the two opposite surfaces in the vertical direction of the wire stranding seat 401. The cooperation between the first guide rod 102 and the first guide hole can keep the wire strand seat 401 on the mounting seat 101, preventing the wire strand seat 401 from detaching from the mounting seat 101 while limiting the movement direction of the wire strand seat 401 to the vertical direction, and supporting the wire strand seat 401 by the first spring 103 sleeved on the first guide rod 102. When the wire strand seat 401 moves on the mounting seat 101, the first spring 103 expands and contracts with the movement of the wire strand seat 401, and when the clamp 403 releases the lead-out wire 11, the elastic force provided by the first spring 103 drives the wire strand seat 401 to reset, so that the wire strand seat 401 can move flexibly on the mounting seat 101.

[0029] Please combine Figure 3 and Figure 4The frame 100 is also provided with a pressing assembly 700, which includes a pressing block 701 and a movable rod 702 connected to the pressing block 701. The pressing block 701 is located directly above the support surface 301, and the axial direction of the movable rod 702 is vertical. The frame 100 is provided with a mounting hole that matches the movable rod 702. The pressing assembly 700 provided on the frame 100 is used to press the stator 1 onto the tray 300. When the tray 300 is driven by the jacking assembly 600 and approaches the stranded wire assembly 400, the pressing block 701 abuts against the upper surface of the stator 1. By clamping the stator 1 between the pressing block 701 and the tray 300, the position of the stator 1 can be fixed, thereby preventing the stator 1 from unexpectedly moving during processing, resulting in a change in the position of the lead wire 11 and affecting the processing.

[0030] Specifically, a second spring 703 is sleeved on the movable rod 702. The opposite ends of the second spring 703 in the extension direction respectively abut against the frame 100 and the pressing block 701, and drive the pressing block 701 to move toward the tray 300. When the tray 300 is lifted up by the lifting assembly 600, the pressing block 701 is lifted up by the stator 1, causing the second spring 703 to be compressed. At this time, the elastic force provided by the second spring 703 keeps the pressing block 701 in contact with the stator 1, ensuring that the position fixed on the tray 300 remains stable. After the tray 300 is reset by the lifting assembly 600, the second spring 703 returns to its original length and drives the pressing block 701 to reset, ensuring that the pressing block 701 can stably cooperate with each stator 1 to be processed during the continuous operation of the stator wire strand cutting device.

[0031] like Figure 4 As shown, the frame 100 is further provided with a guide rail 104, the length direction of which is consistent with the moving direction of the movable seat 501, and the movable seat 501 is respectively provided with a slider 506 that cooperates with the guide rail 104. The guide rail 104 is used to guide the movable seat 501 to move on the frame 100, and the cooperation between the slider 506 and the guide rail 104 reduces the friction between the movable seat 501 and the frame 100, thereby improving the stability of the movable seat 501 during movement and preventing the movable seat 501 from unexpectedly deviating and causing the cutter 503 to be misaligned with the lead wire 11.

[0032] In this embodiment, the third driving member 502 includes two first cylinders 504 and first telescopic rods 505 respectively provided at the output ends of the first cylinders 504. The two first cylinders 504 are respectively located on the side away from each other of the two movable seats 501, and the two first telescopic rods 505 are respectively fixedly connected to the movable seats 501 in a one-to-one correspondence. The first cylinders 504 drive the first telescopic rods 505 to extend or enter the cylinders to drive the movable seats 501 to move on the frame 100. When the two first telescopic rods 505 extend from the first cylinders 504 at the same time, the two movable seats 501 approach each other. At this time, the cutters 503 on the two movable seats 501 dock and cut the lead wires 11. After the cutting is completed, the two first telescopic rods 505 are driven by the corresponding first cylinders 504 to retract into the first cylinders 504, thereby driving the two movable seats 501 to move away from each other, thereby driving the two movable seats 501 to reset.

[0033] Please refer to Figure 1 and Figure 6The lifting assembly 600 also includes a mounting frame 603 fixed on the frame 100 and a movable plate 604 that can be raised and lowered on the mounting frame 603. The fourth driving member 602 is transmission-connected to the movable plate 604. The movable plate 604 is provided with a rotatable connecting rod 605 and a fifth driving member 609 transmission-connected to the connecting rod 605. The end of the connecting rod 605 away from the movable plate 604 is fixedly connected to the lifting plate 601. The jacking assembly 600 also includes the mounting frame 603 fixedly connected to the frame 100, so that the position of the jacking assembly 600 on the frame 100 remains stable, and a movable plate 604 that can be raised and lowered is provided on the mounting frame 603, and the movable plate 604 is connected to the jacking plate 601 through the connecting rod 605. The fourth driving member 602 drives the movable plate 604 to rise and fall on the mounting frame 603, which can drive the jacking plate 601 to rise and fall in the vertical direction, and the fifth driving member 609 drives the connecting rod 605 to rotate, which can drive the jacking plate 601 to rotate, thereby driving the tray 300 and the stator 1 placed on the tray 300 to rotate, so as to adjust the position of the stator 1 so that when the tray 300 is close to the stranded wire assembly 400, the lead wire 11 of the stator 1 extends into the clamping claw 403. In this embodiment, the fourth driving member 602 includes a second cylinder 607 and a second telescopic rod 608 arranged at the output end of the second cylinder 607. The second telescopic rod 608 is fixedly connected to the movable plate 604. The second cylinder 607 drives the second telescopic rod 608 to extend or retract. The second cylinder 607 can drive the movable plate 604 to move, and the fifth driving member 609 is a motor and is connected to the connecting rod 605 in a transmission manner, so as to control the angle of the connecting rod 605 and adjust the stator 1 placed on the tray 300 into place.

[0034] Specifically, the mounting frame 603 is provided with a second guide rod 606, the axial direction of which is aligned with the vertical direction, and the movable plate 604 is provided with a second guide hole that cooperates with the second guide rod 606. The second guide rod 606, provided on the mounting frame 603, is used to limit the movement direction of the movable plate 604, preventing the movable plate 604 from deviating from the vertical direction during movement, which may cause the stator 1 placed on the tray 300 and the stranded wire assembly 400 to be misaligned. The cooperation between the second guide rod 606 and the second guide hole ensures that the movable plate 604 remains horizontal during movement, preventing the movable plate 604 from tilting and causing the stator 1 to fall off the tray 300.

[0035] Please combine Figure 5 and Figure 6In this embodiment, a plurality of positioning pins 610 are provided at intervals on the top surface of the lifting plate 601, and a plurality of positioning holes 302 are provided at intervals on the tray 300, which correspond one-to-one with the positioning pins 610. When the lifting plate 601 moves to a position abutting the tray 300, the positioning pins 610 extend into the corresponding positioning holes 302 to fix the relative positions of the tray 300 and the lifting plate 601, ensuring reliable cooperation between the tray 300 and the lifting plate 601 during movement, preventing the tray 300 from unexpectedly moving and causing the stator 1 on the tray 300 to deviate, and ensuring that the stator 1 is moved to a preset position for processing by the stranding assembly 400 and the shearing assembly 500, thereby improving the reliability of the stator stranding shearing device.
