Description

Technical Field

[0001] The present invention relates to the technical field of stator wire embedding, and particularly to an electrically controllable operation platform for motor stator wire embedding. Background Technique

[0002] ‌Stator wire embedding‌ refers to the process of embedding stator coils into the slots of a motor stator and fixing them. This process has important applications in the power system. Especially in the field of motor manufacturing, stator wire embedding is one of the key steps in motor manufacturing. The wire embedding devices for small motor stators on the market are already very perfect. However, due to the small demand for medium-sized motor stators, there are fewer wire embedding devices for medium-sized motor stators; In the prior art, there is a motor stator wire embedding work platform and its wire embedding method with the authorized announcement number of CN105375710B. When in use, the stator is placed on a conveyor belt. Since the conveyor belt is one of a rubber belt, a steel wire belt, and a chain, when setting the conveyor belt, it is necessary to consider the deformation caused by the weight of the stator. Therefore, the conveyor belt will have some redundancy to prevent the conveyor belt from breaking. However, when there is redundancy, the conveyor belt will deform when pressed. Although it can have a larger contact area, it will also cause the stator to shake more easily, making it easier for the stator to fall on both sides of the conveyor belt and may cause the coils to cross or overlap during wire embedding; Considering that it is relatively difficult to rotate when embedding wires into a medium-sized stator, although using a machine for rotation can save manpower, during the rotation process, it is only supported and rotated by rollers, and the stator may fall off during rotation. Since it is for wire embedding of a medium-sized stator, when the stator falls off, it may cause injury to personnel. Some prior arts will make the equipment operate more safely by increasing the contact surface, but after the equipment starts, the center of gravity of the stator will change due to rotation and will cause the stator to shake. When the stator shakes, it will also be more likely to fall off. At the same time, after the stator shakes, it will also cause the rotation angle to be inaccurate, and may cause the coils to cross or overlap during wire embedding, resulting in unqualified products. Summary of the Invention

A rotating hole is formed on the surface of the adjusting shell near the top. A driven shaft is rotatably connected in the rotating hole. An auxiliary driving wheel is fixedly connected to the outer wall of the driven shaft.

[0005] Further, a plurality of limiting shafts are fixedly connected to the middle part of the adjusting shell. A second fixed shaft and two third fixed shafts are fixedly connected to the inner surface of the adjusting shell near the bottom. The second fixed shaft is located below the third fixed shafts. A driving shaft is rotatably connected between the third fixed shafts. The adjusting unit further includes a rotating gear, which is fixedly connected to the roller. The rotating gear is rotatably connected to the inner surface of the first fixed shaft. The rotating gear meshes with two first gears. The first gears are rotatably connected to the second fixed shaft. The first gears both mesh with second gears. The middle parts of the second gears are fixedly connected to the driving shaft. The outer wall of the driving shaft is symmetrically connected with a second transmission belt in a transmission manner. The side of the second transmission belt away from the driving shaft is connected to the driven shaft in a transmission manner.

[0006] Further, first springs are fixedly connected to the surfaces of the adjusting shells close to each other.

[0007] Further, the transmission unit includes a half gear, the middle part of which is fixedly connected to the output end of the drive motor. The half gear meshes with a transmission gear. A transmission shaft is fixedly connected to the middle part of the transmission gear. A first transmission wheel is fixedly connected to the outer wall of the transmission shaft. The first transmission wheel is rotatably connected to the side cover. The first transmission wheel is connected with a first transmission belt in a transmission manner. The side of the first transmission belt away from the first transmission wheel is connected with a second transmission wheel in a transmission manner. The middle part of the second transmission wheel is fixedly connected to the rotating shaft. A foot pedal is arranged below the operation platform and is electrically connected to the drive motor.

[0008] Furthermore, the limiting unit includes a ratchet and a fixed block, and one end of the rotating shaft close to the side cover is fixedly connected to the ratchet; the inner top surface of the side cover is fixedly connected to the fixed block, and a plurality of limiting holes are provided at the bottom of the fixed block, and a limiting rod is slidably connected in the limiting hole, and the inner top surface of the limiting hole and the limiting rod are fixedly connected by a second spring, and the limiting rod is in sliding contact with the ratchet.

[0009] Furthermore, a plurality of gas storage tanks are fixedly connected to the inner bottom surface of the operating platform, and the tops of the gas storage tanks are fixedly connected to air outlet pipes, which penetrate the top of the operating platform, and the portion of the air outlet pipe located at the top of the operating platform is a bellows.

[0010] Furthermore, the auxiliary wheel is made of flexible material.

[0011] Furthermore, a flexible pad is fixedly connected to the outer wall of the roller.

[0012] The present invention has the following beneficial effects: 1. The present invention first places the stator between two rollers through a crane and supports it through the rollers. At this time, the auxiliary wheel and the roller form a triangle, which has good support and can support and limit the stator. The auxiliary wheel can reduce resistance when the stator rotates, avoiding power loss caused by sliding friction of traditional limiting plates or limiting blocks, preventing angle changes, avoiding angle errors that lead to coil positioning errors, thereby avoiding misaligned slots and wire embedding, preventing electromagnetic force imbalance when misaligned slots and wire embedding, and reducing the risk of short circuits.

[0013] 2. In the present invention, when the driven shaft rotates, the auxiliary wheel will be driven to rotate. Since the auxiliary wheel and the roller form a triangle at this time, the contact area can be increased and the power can be fully utilized. At this time, the stator can be synchronously pushed to rotate by the auxiliary wheel and the roller, which can not only prevent the power from being wasted, but also synchronize the movement of the auxiliary wheel and the roller, that is, the auxiliary wheel rotates when the roller rotates, and the auxiliary wheel does not rotate when the roller does not rotate. This can prevent the auxiliary wheel from rotating when it does not need to rotate due to activities such as the shaking of the stator, thereby preventing the angle of the stator from changing.

[0014] 3. In the present invention, since the outer surface of part of the stator is designed with slots, when the auxiliary wheel passes through the slots, the first spring will contract and make the auxiliary wheel fit the slots. Since the slots are small in size and large in number, a slight collision will occur between the auxiliary wheel and the stator each time the auxiliary wheel fits, which will cause the stator to vibrate. When the stator vibrates, the coils in the embedded wire slots can fill the gaps between them, reducing the process of shaping the coils, so that when the slot wedges are driven in to close the slots, there is no need to reshape them, saving processes and increasing production efficiency.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-8 As shown in the figure, the present invention is a motor stator winding electric controllable operation platform, including an operation platform 1. Six first brackets 11 are fixedly connected to the top of the operation platform 1. Two second brackets 13 are fixedly connected to the top of the operation platform 1. Every three of the first brackets 11 and one second bracket 13 are arranged in a rectangle and are symmetrically arranged about the center of the operation platform 1; A support block 15 is fixedly connected to the top of the operation platform 1. A side cover 12 is fixedly connected to the outer wall of the operation platform 1 close to the second bracket 13. Two drive motors 16 are fixedly connected to the inner bottom surface of the operation platform 1. Transmission units 2 are fixedly connected to the output ends of the drive motors 16. A rotating shaft 17 is fixedly connected to the side of the transmission unit 2 away from the drive motor 16. The rotating shaft 17 is rotatably connected to both the first bracket 11 and the second bracket 13. A roller 18 is fixedly connected to the outer wall of the rotating shaft 17. An adjusting unit 3 is fixedly connected to the surface of the middle part of the roller 18; The adjusting unit 3 includes a first fixed shaft 31. The first fixed shaft 31 is fixedly connected to the support block 15. An adjusting groove is formed on the outer surface of the first fixed shaft 31. Two adjusting outer shells 33 are slidably connected to the surface of the adjusting groove. A rotating hole is formed on the surface of the adjusting outer shell 33 close to the top. A driven shaft 362 is rotatably connected in the rotating hole. An auxiliary driving wheel 37 is fixedly connected to the outer wall of the driven shaft 362.

[0020] In this embodiment, considering that it is relatively difficult to rotate when winding the medium-sized stator, although using a machine for rotation can save manpower, during the rotation process, only the roller 18 is used for support and rotation, and the stator may fall off during rotation. Since it is winding the medium-sized stator, when the stator falls off, it may cause injury to personnel. Some existing technologies will make the equipment operate more safely by increasing the contact surface, but after the equipment starts, the center of gravity of the stator will change due to rotation and will cause the stator to shake. When the stator shakes, it is also easier to fall off. At the same time, after the stator shakes, it will also cause inaccurate rotation angles, and the coils may cross or overlap during winding, resulting in unqualified products; When placing the stator, first place the stator between the two rollers 18 through a crane and support it through the rollers 18. At this time, by adjusting the angle between the adjusting outer shells 33, the auxiliary driving wheel 37 can be brought into contact with the outer surface of the stator, and the stator can be supported and limited. At this time, the auxiliary driving wheel 37 and the roller 18 form a triangle, with good support; When the stator needs to be rotated, the driving motor 16 is started, and the rotating shaft 17 is rotated through the transmission unit 2. When the rotating shaft 17 rotates, the roller 18 will be driven to rotate. Since the stator is in contact with the surface of the roller 18, the stator will be rotated by the frictional force between the stator and the roller 18; The auxiliary wheel 37 can reduce the resistance when the stator rotates, avoiding power loss caused by the sliding friction of the traditional limiting plate or limiting block, preventing the angle from changing, avoiding coil positioning errors caused by incorrect angles, thus avoiding wrong slot insertion, preventing electromagnetic force imbalance caused by wrong slot insertion, reducing the risk of short circuit, and at the same time avoiding the occurrence of periodic radial force to prevent increased wear, thereby improving the production quality of the stator and avoiding the reduction of the stator's service life.

[0021] Specifically, a plurality of limiting shafts 332 are fixedly connected to the middle of the adjusting housing 33. The inner surface of the adjusting housing 33 near the bottom is fixedly connected with a second fixed shaft 331 and two third fixed shafts 341. The second fixed shaft 331 is located below the third fixed shaft 341. A driving shaft 361 is rotatably connected between the third fixed shafts 341; The adjusting unit 3 further includes a rotating gear 32. The rotating gear 32 is fixedly connected to the roller 18. The rotating gear 32 is rotatably connected to the inner surface of the first fixed shaft 31. The rotating gear 32 meshes with two first gears 34. The first gears 34 and the second fixed shaft 331 are both rotatably connected. The first gears 34 both mesh with a second gear 35. The middle of the second gear 35 is fixedly connected to the driving shaft 361. The outer wall of the driving shaft 361 is symmetrically connected with a second transmission belt 36; the side of the second transmission belt 36 away from the driving shaft 361 is connected to a driven shaft 362 in a transmission manner.

[0022] In this embodiment, considering that the contact area between the roller 18 and the stator is small and the transmission efficiency of the rotational force is low, a large amount of kinetic energy will be wasted when only rotating the stator through the roller 18. Although using a transmission belt can transmit all the kinetic energy, it will also cause the stator to shake, increasing the safety risk; When the auxiliary wheel 37 is in contact with the stator, the setting of the rotating gear 32 can drive the rotating gear 32 to rotate when the roller 18 rotates, and drive the first gear 34 to rotate when the rotating gear 32 rotates. When the first gear 34 rotates, the second gear 35 will rotate synchronously. Since the rotation direction of the rotating gear 32 is the same as the rotation direction of the roller 18, but the direction is reversed by the first gear 34, the second gear 35 is required to restore the direction. When the second gear 35 rotates, it will drive the driving shaft 361 to rotate. When the driving shaft 361 rotates, it will transmit power to the driven shaft 362 through the second transmission belt 36, and the driven shaft 362 will rotate synchronously. The shaft 362 rotates, and when the driven shaft 362 rotates, the auxiliary wheel 37 is driven to rotate. Since the auxiliary wheel 37 and the roller 18 are in a triangle at this time, the contact area can be increased and the power can be fully utilized. At this time, the stator can be synchronously pushed to rotate by the auxiliary wheel 37 and the roller 18, which can not only prevent the power from being wasted, but also synchronize the movement of the auxiliary wheel 37 and the roller 18, that is, when the roller 18 rotates, the auxiliary wheel 37 rotates, and when the roller 18 does not rotate, the auxiliary wheel 37 does not rotate. This can prevent the auxiliary wheel 37 from rotating when it does not need to rotate due to the shaking of the stator and other activities, thereby preventing the angle of the stator from changing.

[0023] Specifically, the adjacent side surfaces of the adjustment housing 33 are fixedly connected with the first spring 38 .

[0024] In this embodiment, it is considered that when inserting wires into stators of different sizes, it is necessary to adjust the adjusting housing 33 at different angles; since the position of the first fixed shaft 31 is fixed and the maximum angle of the adjusting slot is also fixed, the first spring 38 can be set to stretch the adjusting housing 33 when clamping the stator, and at this time, the adjusting housing 33 and the auxiliary wheel 37 can adjust the angle according to the size of the stator, so as to adapt to stators of different sizes; when the stator is placed, the first spring 38 will shrink and fit the size of the stator. Since the outer surface of some stators will be slotted, when the auxiliary wheel 37 passes through the slot, the first spring 38 will shrink and make the auxiliary wheel 37 fit the slot. Since the size of the slot is small and the number is large, a small collision will occur between the auxiliary wheel 37 and the stator each time it fits, which will cause the stator to vibrate. When the stator vibrates, the coils in the wire-inserting slots can fill the gaps between them, reducing the process of shaping the coils, so that when the slot wedges are driven into the slots when the slots are closed, there is no need to reshape them, saving processes and increasing production efficiency.

[0025] Specifically, the transmission unit 2 includes a half gear 21. The middle part of the half gear 21 is fixedly connected to the output end of the driving motor 16. The half gear 21 meshes with a transmission gear 22. A transmission shaft is fixedly connected to the middle part of the transmission gear 22. A first transmission wheel 23 is fixedly connected to the outer wall of the transmission shaft. The first transmission wheel 23 is rotatably connected to the side cover 12. The first transmission wheel 23 is connected to a first transmission belt 24. The side of the first transmission belt 24 away from the first transmission wheel 23 is connected to a second transmission wheel 25. The middle part of the second transmission wheel 25 is fixedly connected to the rotating shaft 17. A foot pedal 14 is arranged below the operation platform 1. The foot pedal 14 is electrically connected to the driving motor 16.

[0026] In this embodiment, considering that the equipment needs to rotate a fixed angle when rotating the stator, the rotation speed is slow and the angle is small at this time. In the prior art, the rotation angle is usually not limited. If the start switch is accidentally touched or the foot pedal 14 is accidentally stepped on during wire embedding, the stator may rotate, which may not only cause the coil to be damaged by pulling, but also cause the insulation layer of the wire embedding groove to be damaged due to the friction of the coil, and may cause safety problems such as leakage breakdown when using the motor. After the driving motor 16 is started, the output end of the driving motor 16 will drive the half gear 21 to rotate. When the half gear 21 rotates, it will drive the transmission gear 22 to rotate. Since the half gear 21 has only half of the teeth, the transmission gear 22 will rotate intermittently when rotating, thereby reducing the rotation speed, and the rotation angle of the transmission gear 22 can be limited by the number of turns of the half gear 21. When the transmission gear 22 rotates, it will drive the first transmission belt 24 to transmit power, and the power will be transmitted to the second transmission wheel 25 through the first transmission belt 24. At this time, the second transmission wheel 25 will rotate. When the second transmission wheel 25 rotates, the rotating shaft 17 can be rotated, so that the roller 18 can drive the stator to rotate, and the roller 18 can rotate intermittently through the half gear 21, so that the stator can rotate at a fixed angle, avoiding the problem that the stator rotates too much due to infinite rotation, which makes it difficult to install the coil. At the same time, by replacing the half gear 21 with different specifications, the rotation angle can be changed. Therefore, when processing stators of different sizes, the half gear 21 can be replaced, and each rotation can reach the installation position of the coil, reducing the time required for repeatedly adjusting the stator angle.

[0027] Specifically, the limiting unit 4 includes a ratchet 44 and a fixed block 41. One end of the rotating shaft 17 close to the side cover 12 is fixedly connected to the ratchet 44. The inner top surface of the side cover 12 is fixedly connected to the fixed block 41. A plurality of limiting holes are opened at the bottom of the fixed block 41. A limiting rod 43 is slidably connected in the limiting hole. A second spring 42 is fixedly connected between the inner top surface of the limiting hole and the limiting rod 43. The limiting rod 43 is in sliding contact with the ratchet 44.

[0028] In this embodiment, considering that when the device is in use, the stator may slide down due to the fact that the other side is not fully fixed, which may cause the roller 18 to rotate in the reverse direction. When the roller 18 rotates, it will also cause the stator to rotate in the reverse direction. At this time, the change in the angle of the stator may cause wrong slot wire embedding. At the same time, when the roller 18 rotates, it will also cause the transmission unit 2 to drive the output end of the drive motor 16 to rotate. Considering that some of the existing drive motors 16 do not have reverse protection, it may cause the drive motor 16 to reverse and be damaged; When the stator causes the roller 18 to rotate, the roller 18 at this time will drive the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, it will drive the ratchet wheel 44 to rotate. Since the ratchet wheel 44 rotates in the reverse direction at this time, the limiting rod 43 will be stuck and prevent the ratchet wheel 44 from rotating. Thus, the reverse rotation of the roller 18 can be prevented, and the reverse rotation of the stator can be blocked. When the roller 18 rotates forward, it will cause the limiting rod 43 to move upward along the ratchet teeth of the ratchet wheel 44 and compress the second spring 42.

[0029] Specifically, a plurality of air storage tanks 19 are fixedly connected to the inner bottom surface of the operation platform 1. An air outlet pipe 191 is fixedly connected to the top of each air storage tank 19. The air outlet pipe 191 penetrates through the top of the operation platform 1. The part of the air outlet pipe 191 located at the top of the operation platform 1 is a corrugated pipe.

[0030] In this embodiment, considering that there may be impurities or oil stains in the wire embedding grooves of the stator, if the wire embedding is directly carried out without treatment, it may cause the wires to adhere to the oil stains or be scratched by the impurities. At this time, the wires may leak electricity and cause safety problems; When there are impurities or oil stains in the wire embedding groove, the gas in the air storage tank 19 can be discharged through the air outlet pipe 191 when the stator rotates, and the stator can be purged by the high-pressure gas. Thus, the impurities and oil stains can be removed; when encountering impurities adhering to the wire embedding groove, the auxiliary wheel 37 can repeatedly impact to cause the stator to vibrate, and the impurities can be loosened by the vibration. Subsequently, the high-pressure gas can blow them away from the stator. When the impurities above the stator are vibrated, they can also be blown away by the high-pressure gas when they are about to contact the bottom of the stator.

[0031] Specifically, the auxiliary wheel 37 is made of flexible material.

[0032] In this embodiment, considering that the auxiliary wheel 37 will repeatedly collide with the stator; by using flexible material for the auxiliary wheel 37, the rigid contact when the auxiliary wheel 37 contacts the stator can be changed into flexible contact. Thus, it can be avoided that the auxiliary wheel 37 repeatedly impacts the stator and causes the stator to deform. At the same time, because it is flexible material, after the auxiliary wheel 37 collides with the stator, the auxiliary wheel 37 will bounce multiple times and increase the impact frequency of the auxiliary wheel 37. Thus, not only can the impurities fall off more quickly, but also the installed coils can fill the gaps faster.

[0033] Specifically, a flexible pad 181 is fixedly connected to the outer wall of the roller 18.

[0034] In this embodiment, the arrangement of the flexible pad 181 can not only increase the friction between the roller 18 and the stator, but also increase the contact area between the roller 18 and the stator, enabling better power transmission and further preventing the stator from rotating during wire insertion.

[0035] During use, First, before wire insertion, by replacing the half gears 21 of different specifications, the rotation angle can be changed. Thus, when processing stators of different sizes, the half gears 21 can be replaced, and each rotation can reach the installation position of the coil, reducing the time required for repeatedly adjusting the stator angle. When placing the stator, first place the stator between the two rollers 18 by a crane and support it by the rollers 18. At this time, by adjusting the angle between the adjustment housings 33, the auxiliary driving wheels 37 can be brought into contact with the outer surface of the stator to support and position the stator. At this time, the auxiliary driving wheels 37 and the rollers 18 form a triangle, providing good support. When the stator needs to be rotated, start the driving motor 16, and through the transmission unit 2, the rotating shaft 17 rotates. When the rotating shaft 17 rotates, it drives the roller 18 to rotate. Since the stator is in contact with the surface of the roller 18, the stator rotates due to the friction between the stator and the roller 18. After the driving motor 16 is started, the output end of the driving motor 16 drives the half gear 21 to rotate. When the half gear 21 rotates, it drives the transmission gear 22 to rotate. Since the half gear 21 has only half of the teeth, the transmission gear 22 rotates intermittently during rotation, thereby reducing the rotation speed. Moreover, the rotation angle of the transmission gear 22 can be limited by the number of rotations of the half gear 21. When the transmission gear 22 rotates, it drives the first transmission belt 24 to transmit power, and the power is transmitted to the second transmission wheel 25 through the first transmission belt 24. At this time, the second transmission wheel 25 rotates. When the second transmission wheel 25 rotates, the rotating shaft 17 can be rotated, enabling the roller 18 to drive the stator to rotate. And the roller 18 can rotate intermittently through the half gear 21, enabling the stator to rotate at a fixed angle, avoiding excessive rotation of the stator due to stepless rotation, which may cause difficulties in coil installation. The auxiliary wheel 37 can reduce resistance when the stator rotates, avoid power loss caused by sliding friction of traditional limit plates or limit blocks, prevent angle changes, avoid angle errors leading to coil positioning errors, avoid wrong slots and wire insertion, prevent electromagnetic force imbalance caused by wrong slots and wire insertion, and reduce the risk of short circuits. At the same time, it can also avoid periodic radial forces to prevent increased wear, thereby increasing the production quality of the stator and avoiding a decrease in the life of the stator. The provision of the flexible pad 181 can not only increase the friction between the roller 18 and the stator, but also increase the contact area between the roller 18 and the stator, thereby enabling better power transmission, and can further prevent the stator from rotating during wire embedding.

[0036] Secondly, when the auxiliary wheel 37 contacts the stator, the rotating gear 32 can be set to drive the rotating gear 32 to rotate when the roller 18 rotates, and the first gear 34 can be driven to rotate when the rotating gear 32 rotates. When the first gear 34 rotates, the second gear 35 can be rotated synchronously. Since the rotation direction of the rotating gear 32 is the same as the rotation direction of the roller 18, but the direction is reversed by the first gear 34, the second gear 35 is required to restore the direction. When the second gear 35 rotates, it will drive the driving shaft 361 to rotate. When the driving shaft 361 rotates, it will transmit power to the driven shaft 362 through the second transmission belt 36, and the driven shaft 362 can rotate synchronously. The driving shaft 362 rotates, and when the driven shaft 362 rotates, the auxiliary wheel 37 is driven to rotate. Since the auxiliary wheel 37 and the roller 18 are in a triangle shape at this time, the contact area can be increased and the power can be fully utilized. At this time, the stator can be synchronously pushed to rotate by the auxiliary wheel 37 and the roller 18, thereby not only preventing the power from being wasted, but also synchronizing the movement of the auxiliary wheel 37 and the roller 18, that is, the auxiliary wheel 37 rotates when the roller 18 rotates, and the auxiliary wheel 37 does not rotate when the roller 18 does not rotate. In this way, the auxiliary wheel 37 can be prevented from rotating due to the shaking of the stator when it is not necessary to rotate, thereby preventing the angle of the stator from changing; Since the position of the first fixed shaft 31 is fixed and the maximum angle of the adjustment groove is also fixed, the first spring 38 can be stretched when the adjustment housing 33 clamps the stator. At this time, the adjustment housing 33 and the auxiliary driving wheel 37 can adjust their angles according to the size of the stator, so as to adapt to stators of different sizes; after the stator is placed, the first spring 38 will contract and fit the size of the stator. Since the outer surface of some stators is designed with grooves, when the auxiliary driving wheel 37 passes through the grooves, the first spring 38 will contract and make the auxiliary driving wheel 37 fit the grooves. Since the size of the grooves is small and the number is large, when the auxiliary driving wheel 37 fits each time, there will be a slight collision with the stator, which will cause the stator to vibrate. When the stator vibrates, the coils in the wire embedding grooves can fill the gaps between them, reducing the process of shaping the coils. Therefore, when driving the slot wedges into the closed slot openings, reshaping is not required again, saving the process and increasing the production efficiency; By using a flexible material for the auxiliary driving wheel 37, the rigid contact when the auxiliary driving wheel 37 contacts the stator can be changed into a flexible contact, which can avoid the stator being deformed due to the auxiliary driving wheel 37 repeatedly hitting the stator. At the same time, because it is a flexible material, after the auxiliary driving wheel 37 collides with the stator, the auxiliary driving wheel 37 will bounce multiple times and increase the impact frequency of the auxiliary driving wheel 37. Therefore, not only can impurities fall off more quickly, but also the installed coils can fill the gaps faster.

[0037] Finally, when the stator causes the roller 18 to rotate, the roller 18 will drive the rotating shaft 17 to rotate at this time. When the rotating shaft 17 rotates, it will drive the ratchet wheel 44 to rotate. Since the ratchet wheel 44 rotates in the reverse direction at this time, the limiting rod 43 will block and prevent the ratchet wheel 44 from rotating, thereby preventing the roller 18 from rotating in the reverse direction and preventing the stator from rotating in the reverse direction; When there are impurities or oil stains in the wire embedding grooves, the gas in the air storage tank 19 can be discharged through the air outlet pipe 191 when the stator rotates, and the stator can be purged with high-pressure gas, thereby removing impurities and oil stains; when encountering impurities adhering to the wire embedding grooves, the stator can be vibrated by the auxiliary driving wheel 37 repeatedly hitting, and the impurities can be loosened by the vibration. Subsequently, the impurities can be blown off the stator by high-pressure gas. When the impurities above the stator are vibrated, they can also be blown off by high-pressure gas when they are about to contact the bottom of the stator.
