DETAILED DESCRIPTION

[0043] Typical embodiments embodying the features and advantages of the present invention are described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations herein are intended to be illustrative rather than limiting.

[0044] In the description of this application, it should be understood that in the embodiments shown in the drawings, indications of directions or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions will also change accordingly.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0046] This embodiment discloses a winding machine for a stator, which completes Figure 1 Automatic winding of the ring-shaped stator 1 shown. Figure 1 As shown, the inner side wall of the stator 1 has a plurality of winding posts 11 spaced apart, and winding grooves 12 are formed between adjacent winding posts 11. The winding grooves 12 provide a winding space for the wire 14 to be wound around the winding posts 11. One axial end face of the winding post 11 is a first end face 131, and the other axial end of the winding post 11 is a second end face 132. The stator 1 is wound by winding the wire 14 around the winding post 11, that is, the wire 14 (not shown) sequentially wraps around the winding groove 12 on one side of the winding post 11, the second end face 132 of the winding post 11, the winding groove 12 on the other side of the winding post 11, and the first end face 131 of the winding post 11, thereby completing the process of winding the wire 14 around the winding post 11 for one cycle, and repeating this process to complete the winding of one winding post 11. It is understandable that the wire 14 can be an enameled wire.

[0047] For the convenience of description, the winding groove 12 located on one side of the winding post 11 is a first winding groove 121 , and the winding groove 12 located on the other side of the winding post 11 is a second winding groove 122 .

[0048] For the convenience of description, unless otherwise specified, the front and back directions in this article are expressed as Figure 2 As shown, the end where the lead fixing mechanism 6 is located is the front, and the end where the wire releasing mechanism 8 is located is the rear.

[0049] See also Figure 2 The stator winding machine of this embodiment includes a frame, a positioning mechanism 3, a winding mechanism 4, a wire inserting mechanism 5, a lead fixing mechanism 6, a tensioning mechanism 7 and a wire unwinding mechanism 8.

[0050] The frame is used to install the positioning mechanism 3, the winding mechanism 4, the wire embedding mechanism 5, the lead fixing mechanism 6, the tensioning mechanism 7 and the wire unwinding mechanism 8.

[0051] In some embodiments, the rack includes a first rack 21 and a second rack 22 .

[0052] The first frame 21 is used to install the winding mechanism 4, the wire inserting mechanism 5, the lead fixing mechanism 6 and the tensioning mechanism 7. The second frame 22 is used to install the wire pay-off mechanism 8. The placement positions of the first frame 21 and the second frame 22 can be reasonably adjusted according to the placement space of the stator winding machine.

[0053] See also Figure 2 The positioning mechanism 3 is provided on the top surface of the first frame 21 , and the positioning mechanism 3 is used to position the stator 1 to be wound with the wire 14 and enable the stator 1 to reciprocate around the axis of the stator 1 .

[0054] See also Figure 2 and Figure 3 In some embodiments, the positioning mechanism 3 includes a support plate 32 and a support shaft 31. The support plate 32 is disposed on the top surface of the first frame 21. The support shaft 31 is rotatably disposed above the support plate 32. Two support shafts 31 are provided and are spaced apart and arranged in parallel. Placing the stator 1 on the two support shafts 31 can make the axis of the stator 1 parallel to the axis of the support shafts 31, thereby preventing radial movement of the stator 1 and ensuring that the stator 1 is stably supported.

[0055] Since the support shaft 31 can rotate about its own axis, the stator 1 supported on the support shaft 31 can also rotate about its own axis. When the wire 14 is located on the second end surface 132 of the winding bobbin 11 near the first winding groove 121, the stator 1 can be rotated forward to move the wire 14 to a position on the second end surface 132 of the winding bobbin 11 near the second winding groove 122, so that the wire 14 is wound around the second end surface 132 of the winding bobbin 11.

[0056] Similarly, when the wire 14 is located on the first end face 131 of the winding post 11, close to the second winding groove 122, the stator 1 can be rotated in the opposite direction to move the wire 14 to the first end face 131 of the winding post 11, close to the first winding groove 121, so that the wire 14 is wound around the first end face 131 of the winding post 11.

[0057] Furthermore, after winding one winding post 11 in the stator 1 is completed, the stator 1 can be rotated to wind the next winding post 11 .

[0058] In other embodiments, a rotating shaft may be disposed above the first frame 21, with multiple positioning posts extending radially outward from the shaft. The positioning posts may be provided and spaced circumferentially around the shaft. The shaft is inserted into the stator 1 and positioned along the axis of the stator 1. The positioning posts abut against the winding posts 11, thereby preventing radial movement of the stator 1. Furthermore, the stator 1 can rotate coaxially with the rotating shaft.

[0059] In some embodiments, two support shafts 31 arranged in parallel and spaced apart form a support shaft 31 set. Two support shaft 31 sets are provided and are arranged linearly and spaced apart along the axis of the stator 1. One end of the stator 1 is supported between two support shafts 31 in one support shaft 31 set, and the other end of the stator 1 is supported between two support shafts 31 in the other support shaft 31 set, thereby more stably supporting and positioning the stator 1 and enabling the stator 1 to more stably rotate about its own axis.

[0060] Still see Figure 2 and Figure 3 In some embodiments, the positioning mechanism 3 further includes a clamping plate 33, a clamping shaft 34 and a lifting device 35. The clamping plate 33 is arranged above the support plate 32 at intervals, and the clamping shaft 34 is rotatably arranged below the support plate 32, and the rotation axis of the clamping shaft 34 is parallel to the rotation axis of the support shaft 31, that is, the rotation axis of the clamping shaft 34 is parallel to the rotation axis of the stator 1. The clamping plate 33 can be lifted up and down under the drive of the lifting device 35. When the stator 1 is supported on the support shaft 31, the clamping plate 33 can be moved downward under the drive of the lifting device 35, so that the interval between the clamping shaft 34 and the support shaft 31 becomes smaller, and then the two clamping shafts 34 can be against the stator 1, further preventing the stator 1 from radial movement. In addition, since the clamping shaft 34 can also rotate around its own axis, it does not affect the rotation of the stator 1.

[0061] When the winding is complete and the stator 1 needs to be removed, the pressing plate 33 moves upward under the drive of the lifting device 35, increasing the distance between the pressing shaft 34 and the support shaft 31, separating the pressing shaft 34 from the stator 1. The downward force exerted by the pressing shaft 34 on the stator 1 disappears, allowing the wound stator 1 to be removed. In addition, because the lifting device 35 can drive the pressing plate 33 up and down to adjust the distance between the pressing shaft 34 and the support shaft 31, stators 1 of different sizes can be fixed.

[0062] In some embodiments, two parallel, spaced-apart compression shafts 34 form a compression shaft 34 set. Two sets of compression shafts 34 are provided, spaced linearly along the axis of the stator 1. Driven by the lifting device 35, the compression plate 33 and compression shafts 34 can move downward, with the two compression shafts 34 in one set of compression shafts 34 resting against one end of the stator 1, and the two compression shafts 34 in the other set of compression shafts 34 resting against the other end of the stator 1, thereby better preventing radial movement of the stator 1.

[0063] In some embodiments, the lifting device 35 includes a first cylinder 351, which is positioned above the pressure plate 33. The piston rod of the first cylinder 351 is connected to the pressure plate 33. Therefore, when the piston rod of the first cylinder 351 extends, it drives the pressure plate 33 and the pressure shaft 34 to move downward in sync. When the piston rod of the first cylinder 351 contracts, it drives the pressure plate 33 and the pressure shaft 34 to move upward in sync.

[0064] In some embodiments, the support plate 32 is slidably connected to the top surface of the first frame 21. Therefore, after completing the winding of a stator 1, the lifting device 35 is used to separate the clamping shaft 34 from the stator 1, and then the support plate 32 is slid to drive the support shaft 31 and the stator 1 supported on the support shaft 31 to move synchronously and move to a position away from the clamping shaft 34 and the clamping plate 33, so that the stator 1 can be taken out more conveniently. When it is necessary to wind the next stator 1, the next stator 1 to be wound can be placed on the support shaft 31, and the support plate 32 is slid again to make the support shaft 31 and the next stator 1 to be wound move synchronously to the bottom of the clamping plate 33. The clamping plate 33 moves downward under the drive of the lifting device 35 so that the clamping shaft 34 is pressed against the next stator 1 to be wound to complete the positioning.

[0065] See also Figure 4 and Figure 5 In some embodiments, the positioning mechanism 3 further includes a first driving assembly 36. The first driving assembly 36 is in driving connection with the stator 1 and is used to drive the stator 1 to rotate back and forth.

[0066] In some embodiments, the first drive assembly 36 includes a ring gear 362 and a gear 361. The ring gear 362 is detachably mounted on the stator 1 and is capable of coaxially rotating with the stator 1. The gear 361 and the ring gear 362 are meshed and connected to each other, so that when the gear 361 is rotated, the ring gear 362 can be driven to rotate synchronously.

[0067] In some other embodiments, the gear 361 may not be required. A sprocket may be provided, and the sprocket and the ring gear 362 may be connected via a chain drive. When the sprocket rotates, the ring gear 362 may be driven to rotate synchronously.

[0068] In some embodiments, the ring gear 362 is sleeved on the middle part of the stator 1. The ring gear 362 is located between the two groups of support shafts 31 and between the two groups of clamping shafts 34. Therefore, when the ring gear 362 rotates, it can drive the stator 1 to rotate more smoothly.

[0069] In some embodiments, the first driving assembly 36 includes a plurality of gear rings 362 with different inner diameters, so that the first driving assembly 36 can be used to fix stators 1 with different diameters.

[0070] In some other embodiments, a plurality of adjustment posts are protruding from the inner circumferential wall of the ring gear 362, and the plurality of adjustment posts are spaced apart around the circumference of the ring gear 362. An adjustment ring is threadedly connected to the adjustment post. The adjustment ring can be rotated to extend the end of the adjustment post away from the inner circumferential wall of the ring gear 362 so that the adjustment ring abuts against the stator 1, thereby securing the stator 1 within the ring gear 362 and enabling the ring gear 362 to rotate coaxially with the stator 1. Furthermore, the distance the adjustment ring extends from the end of the adjustment post away from the inner circumferential wall of the ring gear 362 can be adjusted by rotating the adjustment ring to secure stators 1 of different diameters.

[0071] In some embodiments, the first drive assembly 36 also includes a first motor 363, which is a forward and reverse motor. The gear 361 is provided on the output shaft of the first motor 363. When the output shaft of the first motor 363 rotates, it can drive the gear 361 to rotate, thereby driving the ring gear 362 and the stator 1 to rotate.

[0072] In some other embodiments, the first motor 363 may also be in transmission connection with one of the support shafts 31 to drive the support shaft 31 to rotate, thereby generating friction between the support shaft 31 and the stator 1 to drive the stator 1 to rotate.

[0073] In some embodiments, the first drive assembly 36 further includes a mounting base 364. The first motor 363 is mounted on the mounting base 364, which is hinged to one side of the stator 1, with the rotation axis of the mounting base 364 parallel to the rotation axis of the stator 1. Therefore, when using ring gears 362 of different diameters to secure stators 1 of different diameters, the position of the gear 361 can be adjusted by rotating the mounting base 364, so that the gear 361 can mesh with the ring gears 362 of different diameters.

[0074] See also Figure 6 and Figure 7 In some embodiments, the positioning mechanism 3 further includes an angular displacement sensor 37. The angular displacement sensor 37 is used to detect the rotation angle of the stator 1. The first drive assembly 36 includes a control unit, and the control unit is electrically connected to the angular displacement sensor 37. The control unit is used to control the first drive assembly 36 based on the rotation angle. For example, the angular displacement sensor 37 is electrically connected to the first motor 363. The angular displacement sensor 37 can control the rotation angle of the first motor 363 based on the measured rotation angle of the stator 1.

[0075] See also Figure 7In some embodiments, the lifting device 35 further includes a second cylinder 352. The second cylinder 352 is disposed on the pressing plate 33. The piston rod of the second cylinder 352 is connected to the angular displacement sensor 37. Thus, the second cylinder 352 can be used to drive the angular displacement sensor 37 to move up and down. When winding stators 1 of different diameters, the second cylinder 352 can be used to adjust the position of the angular displacement sensor 37, so that the angular displacement sensor 37 can be used to measure the rotation angle of stators 1 of different diameters.

[0076] See also Figure 2 The winding mechanism 4 is provided on the first frame 21 and is located behind the positioning mechanism 3 . The winding mechanism 4 is used to pull the wire 14 to move back and forth along the winding column 11 .

[0077] See also Figure 2 and Figure 8 The winding mechanism 4 includes a guide rail 41 and a lead assembly 42. The lead assembly 42 is used to pull the wire 14 to move, and the lead assembly 42 is slidably connected to the guide rail 41. When the stator 1 to be wound is placed on the support shaft 31 and the support plate 32 is moved so that the support shaft 31 is located below the clamping shaft 34, the guide rail 41 is passed through the inner side of the stator 1, and the first end face 131 and the second end face 132 of the winding post 11 are located between the two ends of the guide rail 41. The guide rail 41 extends along the axial direction of the stator 1 and is parallel to the axis of the support shaft 31, so that the guide rail 41 can be parallel to the axis of the stator 1 supported on the support shaft 31.

[0078] When the lead assembly 42 moves back and forth along the guide rail 41 , the lead assembly 42 can pull the wire 14 from the first end surface 131 to the second end surface 132 of the winding post 11 , and the lead assembly 42 can also pull the wire 14 from the second end surface 132 to the first end surface 131 of the winding post 11 .

[0079] In some embodiments, the winding mechanism 4 further includes a second drive assembly 43. The second drive assembly 43 is used to drive the lead assembly 42 to reciprocate on the guide rail 41, so that the lead assembly 42 can automatically pull the wire 14 to reciprocate between the first end surface 131 and the second end surface 132 of the winding post 11, saving manpower and reducing the cost of winding the stator 1.

[0080] In some embodiments, the second drive assembly 43 includes a screw rod 431 and a second motor 432. A groove 411 is recessed on the guide rail 41, and the screw rod 431 is opposite to the groove 411 and parallel to the groove 411. The second motor 432 is a forward and reverse motor, which is connected to the screw rod 431 and drives the screw rod 431 to rotate forward and reverse. The lead assembly 42 is rotatably threaded to the screw rod 431, and the lead assembly 42 is slidably connected to the groove 411, so that the lead assembly 42 slides back and forth along the groove 411 under the drive of the screw rod 431. The groove 411 is then used to guide the movement of the lead assembly 42 and define the motion trajectory of the lead assembly 42.

[0081] In some embodiments, the second drive assembly 43 further includes a third motor 433. The guide rail 41 is mounted on a mounting plate 44. The third motor 433 is in driving connection with the mounting plate 44 and drives the mounting plate 44 to move up and down, thereby enabling the guide rail 41 on the mounting plate 44 to also move up and down. When winding stators 1 of different diameters, the third motor 433 can be used to drive the mounting plate 44 and the guide rail 41 up and down to adjust the height of the guide rail 41, allowing the guide rail 41 to pass through stators 1 of different diameters.

[0082] See also Figure 9 In some embodiments, the lead assembly 42 includes a lead block 421, a lead plate 422, and a lead wheel 423. The lead block 421 is rotatably threaded to the lead rod 431, and the lead block 421 is slidably connected to the slide 411. The lead block 421 is driven by the lead rod 431 to slide back and forth linearly along the slide 411. The lead plate 422 is connected to the lead block 421, and there are two lead plates 422, which are arranged in parallel and spaced apart. The lead wheel 423 is arranged between the two lead plates 422 and is rotatably connected to the lead plates 422, and the rotation axis of the lead wheel 423 is perpendicular to the lead plates 422. There are two lead wheels 423, and the two lead wheels 423 are arranged at an interval, and a lead groove 427 is formed between the two lead wheels 423 to pull the wire 14 to move. The wire pulley 423 can be rotated so that the wire 14 can move more smoothly in the wire groove formed by the two wire pulleys 423 .

[0083] In some embodiments, a wire pulley 423 is provided with two wire loops 424 circumferentially protruding from the wire pulley 423, and the wire loops 424 are provided in parallel and spaced apart arrangement. The wire loops 424 circumferentially of the two wire pulleys 423 are arranged in close contact with each other, wherein the two wire loops 424 on one wire pulley 423 and the two wire loops 424 on the other wire pulley 423 enclose a wire groove 427. The wire 14 moves within the wire groove 427 formed by the wire loops 424, which can prevent the wire 14 from escaping from the wire pulley 423.

[0084] Continue reading Figure 9 In some embodiments, the lead assembly 42 further includes a guide wheel 425. The guide wheel 425 is disposed between the two lead plates 422 and is rotatably connected to the lead plates 422, and the rotation axis of the guide wheel 425 is parallel to the reversing wheel 72. The wire 14 enters the lead groove after being reversed by the guide wheel 425, allowing the wire 14 to enter the lead groove more smoothly, thereby avoiding the wire 14 from being directly pulled into the lead groove by the lead wheel 423 and causing significant deformation. It is understandable that the guide wheel 425 is provided with a guide groove 426 inwardly concave in the axial direction to prevent the wire 14 from escaping from the guide wheel 425 when the wire 14 moves in the guide groove 426.

[0085] See also Figure 2 The wire inserting mechanism 5 is provided on the first frame 21. The wire inserting mechanism 5 is used to pull the wire 14 into the winding groove 12, and the wire inserting mechanism 5 cooperates with the winding mechanism 4 to wind the wire 14 around the winding column 11.

[0086] See also Figure 10 and Figure 11 , and combined with Figure 2 Specifically, the wire inserting mechanism 5 includes a first wire inserting mechanism 51 and a second wire inserting mechanism 52. The first wire inserting mechanism 51 is located outside the first end surface 131, and the second wire inserting mechanism 52 is located outside the second end surface 132. During winding, the stator 1 is rotated so that the lead assembly 42 is aligned with the first winding groove 121. The lead assembly 42 pulls the wire 14 over the first winding groove 121.

[0087] When the lead assembly 42 pulls the wire 14 from the first end face 131 of the winding post 11 to the second end face 132, the second wire embedding mechanism 52 pulls the wire 14 to move, so that the wire 14 enters the first winding groove 121, and moves the wire 14 to a position on the second end face 132 of the winding post 11 close to the first winding groove 121, and then rotates the stator 1 forward to move the wire 14 to a position on the second end face 132 of the winding post 11 close to the second winding groove 122, so that the wire 14 is wound around the second end face 132 of the winding post 11.

[0088] When the lead assembly 42 pulls the wire 14 from the second end face 132 of the winding post 11 to the first end face 131, the first wire embedding mechanism 51 pulls the wire 14 to move, so that the wire 14 enters the second winding groove 122, and moves the wire 14 to a position on the first end face 131 of the winding post 11 close to the second winding groove 122, and then rotates the stator 1 in the opposite direction to move the wire 14 to a position on the first end face 131 of the winding post 11 close to the first winding groove 121, so that the wire 14 is wound around the first end face 131 of the winding post 11.

[0089] This completes the process of directly winding the wire 14 around the winding post 11 for one full turn. This process is repeated to complete the winding of one winding post 11. There is no need to first wind the wire 14 into a coil and then wrap it around the winding post 11. This improves winding efficiency and reduces the production cost of the stator 1. The stator 1 is rotated and the winding process continues on the next winding post 11 to complete the winding of the entire stator 1. This achieves high winding precision and good consistency, reducing the consumption of the wire 14.

[0090] Furthermore, during the above winding process, the lead assembly 42 is always located outside the winding slot 12. The lead assembly 42 does not need to enter the winding slot 12, thus not occupying the winding space within the winding slot 12. This allows more wire 14 to be wound around the winding post 11, thereby increasing the slot fill rate of the stator 1 winding and thereby improving the performance of the motor. At the same time, the lead assembly 42 is prevented from moving within the winding slot 12 and scratching the already wound wire 14.

[0091] See also Figure 12 In some embodiments, each wire inserting mechanism 5 includes an actuator 53 and a power group 54. The actuator 53 is used to pull the wire 14 to move. The power group 54 is in transmission connection with the actuator 53 to drive the actuator 53 to move.

[0092] The executive part 53 extends vertically and is arranged below the lead assembly 42. A bayonet 531 is provided at the upper end of the executive part 53. The power group 54 includes a first power member 541, which is transmission-connected to the executive part 53 and drives the executive part 53 to move up and down. When the first power member 541 drives the bayonet 531 to move upward to above the winding groove 12, the bayonet 531 can hook the wire 14 on the lead assembly 42, so that the executive part 53 can pull the wire 14 to move. When the first power member 541 drives the bayonet 531 to move downward to face the winding groove 12, the bayonet 531 pulls the wire 14 into the winding groove 12.

[0093] In some embodiments, the power group 54 further includes a second power member 542. The second power member 542 is connected to and drives the actuator 53 to rotate. When the second power member 542 drives the actuator 53 to rotate and causes the bayonet 531 to face the wire 14, the bayonet 531 can hook onto the wire 14, and the actuator 53 can then pull the wire 14 to move. When the second power member 542 drives the actuator 53 to rotate and causes the bayonet 531 to face away from the wire 14, the wire 14 is disengaged from the bayonet 531. The first power member 541 is in transmission connection with the second power member 542 and drives the second power member 542 to move up and down, thereby synchronously driving the actuator 53 to move up and down.

[0094] In some embodiments, the power group 54 further includes a third power member 543. The third power member 543 is in transmission connection with the first power member 541 and drives the first power member 541 to move forward and backward, thereby synchronously driving the second power member 542 and the actuator 53 to move forward and backward.

[0095] Therefore, the first power member 541 can drive the executing part 53 to move up and down, the second power member 542 can drive the executing part 53 to rotate, and the third power member 543 can drive the executing part 53 to move forward and backward.

[0096] See also Figures 10 to 12 The following describes the operation process of the first thread inserting mechanism 51 and the second thread inserting mechanism 52 in detail in combination with the above embodiment:

[0097] Step 1: When the lead assembly 42 pulls the wire 14 and is positioned on the first end surface 131 of the winding post 11 and directly above the second winding groove 122, the actuator 53 of the first wire-entering mechanism 51 is positioned directly opposite the second winding groove 122. The second power member 542 of the first wire-entering mechanism 51 drives the actuator 53 to rotate, causing the latch 531 to face the winding post 11, that is, facing the wire 14. The first power member 541 of the first wire-entering mechanism 51 drives the actuator 53 upward and moves it above the second winding groove 122, allowing the latch 531 to hook onto the wire 14 on the lead assembly 42. The first power member 541 of the first wire-embedding mechanism 51 then drives the actuator 53 downward. When the actuator 53 is aligned with the second winding groove 122, the latch 531 pulls the wire 14 into the second winding groove 122. The latch 531 is positioned near the first end surface 131 of the winding post 11 and the second winding groove 122. The stator 1 is rotated in the reverse direction, moving the wire 14 to a position on the first end surface 131 of the winding post 11 near the first winding groove 121, allowing the wire 14 to wrap around the first end surface 131 of the winding post 11.

[0098] Step 2: The lead assembly 42 pulls the wire 14 from the first end face 131 to the second end face 132 of the winding post 11, and the wire 14 moves above the first winding groove 121. When the wire 14 moves from the first end face 131 to near the second end face 132, the second power member 542 of the first wire inserting mechanism 51 drives the actuator 53 to rotate, causing the latch 531 to face away from the wire 14, and the wire 14 will be disengaged from the latch 531. The first power member 541 of the first wire inserting mechanism 51 then drives the actuator 53 to move downward to below the first winding groove 121, and the actuator 53 of the first wire inserting mechanism 51 is disengaged from the wire 14.

[0099] The actuator 53 of the second wire-entering mechanism 52 is positioned directly opposite the first winding groove 121. The second power member 542 of the second wire-entering mechanism 52 rotates the actuator 53, causing the latch 531 to face the winding post 11, that is, facing the wire 14. The first power member 541 of the second wire-entering mechanism 52 drives the actuator 53 upward, moving it above the first winding groove 121 so that the latch 531 can hook onto the wire 14 on the lead assembly 42. The first power member 541 of the second wire-entering mechanism 52 then drives the actuator 53 downward, until it faces the first winding groove 121. The latch 531 then pulls the wire 14 into the first winding groove 121, and the latch 531 is positioned on the second end surface 132 of the winding post 11, near the first winding groove 121. The stator 1 rotates forward to move the wire 14 to a position on the second end surface 132 of the winding bobbin 11 close to the second winding groove 122 , so that the wire 14 is wound around the second end surface 132 of the winding bobbin 11 .

[0100] Step 3: The lead assembly 42 pulls the wire 14 from the second end face 132 of the winding post 11 to the first end face 131, and the wire 14 moves above the second winding groove 122. When the wire 14 moves from the second end face 132 to near the first end face 131, the second power member 542 of the second wire inserting mechanism 52 drives the actuator 53 to rotate, causing the latch 531 to face away from the wire 14, and the wire 14 will be disengaged from the latch 531. The first power member 541 of the second wire inserting mechanism 52 then drives the actuator 53 to move downward to below the second winding groove 122, and the second wire inserting mechanism 52 is disengaged from the wire 14.

[0101] The actuator 53 of the first wire-entering mechanism 51 is positioned directly opposite the second winding groove 122. The second power member 542 of the first wire-entering mechanism 51 rotates the actuator 53, causing the latch 531 to face the winding post 11, that is, facing the wire 14. The first power member 541 of the first wire-entering mechanism 51 drives the actuator 53 upward, moving it above the second winding groove 122, allowing the latch 531 to hook onto the wire 14 on the lead assembly 42. The first power member 541 of the first wire-entering mechanism 51 then drives the actuator 53 downward, until it faces the second winding groove 122. The latch 531 then pulls the wire 14 into the second winding groove 122, and the latch 531 is positioned on the first end surface 131 of the winding post 11, near the second winding groove 122. The stator 1 is rotated in the reverse direction to move the wire 14 to a position on the first end surface 131 of the winding bobbin 11 close to the first winding groove 121 , so that the wire 14 is wound around the first end surface 131 of the winding bobbin 11 .

[0102] Repeat the second and third steps to complete the winding of a winding post 11. It should be noted that during the winding process, multiple turns of wire 14 are wound on the winding post 11 gradually from the upper end to the lower end. Then, multiple turns of wire 14 of the second layer are wound on the winding post 11 gradually from the lower end to the upper end. When winding the second layer of wire 14, since the first layer of wire 14 has a certain thickness, when winding the second layer of wire 14, the third power member 543 of the first wire embedding mechanism 51 needs to drive the executive part 53 to move forward a distance to avoid the thickness of the first layer of wire 14, and the third power member 543 of the second wire embedding mechanism 52 needs to drive the executive part 53 to move backward a distance to avoid the thickness of the first layer of wire 14. When winding more layers of wire 14 , the third power member 543 of the first wire inserting mechanism 51 drives the executing portion 53 to move forward a greater distance in sequence, and the third power member 543 of the second wire inserting mechanism 52 drives the executing portion 53 to move backward a greater distance in sequence.

[0103] In some embodiments, the first power member 541 , the second power member 542 , and the third power member 543 may be forward and reverse motors.

[0104] See also Figure 2 The lead wire fixing mechanism 6 is provided on the first frame 21 and is located in front of the positioning mechanism 3 . The lead wire fixing mechanism 6 is used to fix the wire 14 .

[0105] See also Figure 2 and Figure 13 The lead wire fixing mechanism 6 includes a bracket 61 and a turntable 62. The bracket 61 is mounted on the first frame 21 and is located outside the first end surface 131. The turntable 62 is rotatably mounted on the bracket 61 and is located between the first end surface 131 and the bracket 61. The turntable 62 includes a disk body 621 and a plurality of fixing posts 622 surrounding the disk body 621. The fixing posts 622 correspond to the winding posts 11.

[0106] Before winding the first winding pin 11, the end of the wire 14 can be fixed to the corresponding winding pin 11. Since winding the first winding pin 11 requires the second winding pin 11 to be wound after the first winding pin 11 is wound, the stator 1 needs to be rotated and the position of the first winding pin 11 needs to be changed. Therefore, synchronously rotating the fixed pin 622 corresponding to the first winding pin 11 can prevent the wire 14 fixed to the corresponding fixed pin 622 from being pulled when the position of the first winding pin 11 changes, causing the wire 14 already wound on the first winding pin 11 to fall off the winding pin 11.

[0107] Each time the next winding post 11 is wound, the wire 14 is fixed to the corresponding winding post 11 to prevent the wire 14 already wound on the winding post 11 from escaping. After the winding of the entire stator 1 is completed, an extra section of wire 14 is pulled onto the fixing post 622 between adjacent winding posts 11 and can be used as inter-pole connection wire.

[0108] In some embodiments, the lead fixing mechanism 6 further includes a fourth motor, which is a forward and reverse motor. The fourth motor is connected to and drives the turntable to rotate automatically.

[0109] In some embodiments, the bracket 61 is disposed on the support plate 32 . Since the support plate 32 is slidably connected to the first frame 21 , the bracket 61 and the turntable 62 can slide synchronously when the support plate 32 slides.

[0110] In some embodiments, the bracket 61 is slidably connected to the support plate 32 , and the length of the inter-electrode connection line can be adjusted by sliding the bracket 61 on the support plate 32 .

[0111] See also Figure 2 The tensioning mechanism 7 is provided on the first frame 21 and is located behind the positioning mechanism 3. The tensioning mechanism 7 controls the tension of the wire 14 during the winding process.

[0112] See also Figure 8 The tensioning mechanism 7 includes a rotating rod 71 and a reversing wheel 72. The rotating rod 71 is rotatably connected to the mounting plate 44, and the reversing wheel 72 is rotatably connected to the rotating rod 71. Multiple reversing wheels 72 are provided and arranged in parallel and spaced apart. The wire 14 is arranged in an S-shape through the spaces between adjacent reversing wheels 72.

[0113] During the winding process, one end of the wire 14 needs to be fixed to the fixing post 622 to provide tension at the other end of the wire 14. Therefore, when the rotating rod 71 rotates, the wire 14 can be tightened or loosened to adjust the tension of the wire 14 during the winding process.

[0114] It should be noted that when the lead assembly 42 pulls the wire 14 from the second end face 132 of the winding post 11 to the first end face 131, the wire 14 has already been fed forward a sufficient length to wrap around the winding post 11. Therefore, when the lead assembly 42 pulls the wire 14 from the first end face 131 to the second end face 132 of the winding post 11, since this process does not require further feeding, the lead assembly 42 cannot provide tension to the wire 14. At this time, the tensioning mechanism 7 tensions the wire 14 to ensure tension during the winding process.

[0115] In some embodiments, the tensioning mechanism 7 further includes a third cylinder 73, which is hinged to the rotating rod 71. The rotating rod 71 can be automatically driven to rotate by extending or contracting the piston rod of the third cylinder 73.

[0116] See also Figure 2 The pay-off mechanism 8 is provided on the second frame 22 and is located behind the tensioning mechanism 7. The pay-off mechanism 8 is used to provide a plurality of wires 14 required in the winding process.

[0117] See also Figure 14 and Figure 15 In some embodiments, the wire-releasing mechanism 8 includes a plurality of wire posts 81 arranged in multiple rows, each row containing multiple wire posts 81. The wire posts 81 are provided with first wire holes 811, and multiple bundles of wires 14 are passed through corresponding first wire holes 811 to prevent the wires 14 from becoming entangled. Each first wire hole 811 can be passed through one or more wires 14.

[0118] In some embodiments, the pay-off mechanism 8 further includes a wire guide 82 disposed at the front end of the second frame 22. The wire guide 82 is provided with a plurality of second wire holes 821. After passing through the first wire holes 811, the wires 14 are passed through the second wire holes 821 in a one-to-one correspondence. That is, only one wire 14 passes through each second wire hole 821, further preventing the wires 14 from becoming entangled.

[0119] It should be noted that only two wires 14 can pass through each first wire hole 811 on a row of wire posts 81 close to the wire plate 82 to prevent the wires 14 from being entangled.

[0120] In some embodiments, ceramic rings are provided in the first wire hole 811 and the second wire hole 821 to prevent the wire 14 from being scratched.

[0121] See also Figures 14 to 16 In some embodiments, the pay-off mechanism 8 further includes a plurality of pre-tightening devices 83. The pre-tightening devices 83 are used to control the tension of the wire 14 during the winding process.

[0122] The preload device 83 includes a screw 831, a stopper 832, an adjustment portion 833, an adjustment plate 834, and an elastic member 835. The stopper 832 is located at one end of the screw 831, and the adjustment portion 833 is threadedly connected to the other end of the screw 831. The screw 831 is movably mounted on the adjustment plate 834, and the adjustment plate 834 is located between the stopper 832 and the adjustment portion 833. Two adjustment plates 834 are provided and spaced apart in parallel. The elastic member 835 is sleeved on the screw 831, with one end of the elastic member 835 abutting the adjustment portion 833 and the other end abutting the adjustment plate 834.

[0123] The wire 14 is sandwiched between the two adjustment plates 834. When the adjustment portion 833 is rotated forward, the elastic member 835 is gradually compressed, causing the elastic member 835 to squeeze the adjustment plates 834. This reduces the distance between the two adjustment plates 834, increases the friction between the adjustment plates 834 and the wire 14, and thus provides greater tension for the wire 14. When the adjustment portion 833 is rotated backward, the elastic member 835 gradually recovers its deformation, reducing the force exerted by the elastic member 835 on the adjustment plates 834. This increases the distance between the two adjustment plates 834, reduces the friction between the adjustment plates 834 and the wire 14, and thus reduces the tension applied to the wire 14.

[0124] It should be noted that the stator winding machine of this embodiment is suitable for winding large stators 1 and can realize the winding of multiple wires 14 in parallel, thereby improving the winding efficiency. Therefore, during the winding process, it is necessary to provide a large tension for the wires 14. The tensioning mechanism 7 cooperates with the pre-tightening device 83 to ensure the required tension during the winding process.
