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;

[0003] In the prior art, a motor stator wire embedding work platform and its wire embedding method with the authorization announcement number CN105375710B place the stator on a conveyor belt during use. Since the conveyor belt is one of a tape, a steel wire belt, and a chain, and the conveyor belt needs to consider the deformation caused by the weight of the stator during setting, 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 the stator more likely to fall on both sides of the conveyor belt and may cause the coils to cross or overlap during wire embedding;

[0004] Considering that it is relatively difficult to rotate a medium-sized stator during wire embedding, using a machine for rotation can save manpower, but during the rotation process, it is only supported and rotated by rollers, and the stator may fall off during rotation. Since it is a medium-sized stator for wire embedding, when the stator falls off, it may cause injury to personnel. Some prior arts make the equipment run 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 cause the stator to shake. When the stator shakes, it is also more likely to fall off. At the same time, after the stator shakes, the rotation angle will not be accurate, and during wire embedding, the coils may cross or overlap, resulting in unqualified products. Summary of the Invention

[0005] The purpose of the present invention is to provide an electrically controllable operation platform for motor stator wire embedding to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions:

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.

[0010] Furthermore, a plurality of limiting shafts are fixedly connected to the middle part of the adjusting outer shell. A second fixed shaft and two third fixed shafts are fixedly connected to the inner surface of the adjusting outer shell close to the bottom. The second fixed shaft is located below the third fixed shafts. A driving shaft is rotatably connected between the third fixed shafts;

[0011] The adjusting unit further includes a rotating gear, which is fixedly connected with the roller. The rotating gear is rotatably connected with the inner surface of the first fixed shaft. The rotating gear meshes with two first gears. The first gears are rotatably connected with the second fixed shaft. The first gears both mesh with second gears. The middle parts of the second gears are fixedly connected with the driving shaft. The outer wall of the driving shaft is symmetrically and drivingly connected with a second transmission belt; One side of the second transmission belt far away from the driving shaft is drivingly connected with the driven shaft.

[0012] Furthermore, first springs are fixedly connected to the surfaces of the adjusting outer shells close to each other.

[0013] Further, the transmission unit includes a half gear, the middle of the half gear is fixedly connected to the output end of the driving motor, and the half gear meshes with a transmission gear; a transmission shaft is fixedly connected to the middle of the transmission gear, and 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 to a first transmission belt, and the side of the first transmission belt away from the first transmission wheel is connected to a second transmission wheel. The middle of the second transmission wheel is fixedly connected to the rotating shaft; a foot pedal is arranged below the operation platform, and the foot pedal is electrically connected to the driving motor.

[0014] Further, the limiting unit includes a ratchet wheel and a fixing block. One end of the rotating shaft close to the side cover is fixedly connected to the ratchet wheel; the inner top surface of the side cover is fixedly connected to the fixing block. A plurality of limiting holes are opened at the bottom of the fixing block, and a limiting rod is slidably connected in the limiting holes. A second spring is fixedly connected between the inner top surface of the limiting hole and the limiting rod, and the limiting rod is in sliding contact with the ratchet wheel.

[0015] Further, a plurality of air storage tanks are fixedly connected to the inner bottom surface of the operation platform. An air outlet pipe is fixedly connected to the top of each air storage tank. The air outlet pipe penetrates through the top of the operation platform, and the part of the air outlet pipe located at the top of the operation platform is a corrugated pipe.

[0016] Further, the auxiliary driving wheel is made of a flexible material.

[0017] Further, a flexible pad is fixedly connected to the outer wall of the roller.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the present invention, the stator is first placed between two rollers by a crane and supported by the rollers. At this time, the auxiliary driving wheel and the rollers form a triangle, which has good support and can support and limit the stator. The auxiliary driving wheel can reduce the resistance when the stator rotates, avoiding power loss caused by the sliding friction of traditional limiting plates or blocks, preventing angle changes, avoiding coil positioning errors caused by angle errors, thus avoiding wrong slot insertion, preventing electromagnetic force imbalance caused by wrong slot insertion, and reducing the risk of short circuit.

[0020] 2. When the driven shaft rotates in the present invention, it will drive the auxiliary driving wheel to rotate. Since the auxiliary driving wheel and the rollers form a triangle at this time, while increasing the contact area, the power can be fully utilized. At this time, the stator can be synchronously pushed to rotate through the auxiliary driving wheel and the rollers. Thus, not only can the waste of power be prevented, but also the movement of the auxiliary driving wheel and the rollers can be synchronized, that is, when the rollers rotate, the auxiliary driving wheel rotates, and when the rollers do not rotate, the auxiliary driving wheel does not rotate. Thus, it can prevent the auxiliary driving wheel from rotating due to the shaking or other activities of the stator when rotation is not required, thereby preventing the angle of the stator from changing.

[0021] 3. In the present invention, the outer surface of a 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 size of the slots is small and the number is large, there will be a slight collision between the auxiliary wheel and the stator every time the auxiliary wheel fits. At this time, the stator will vibrate. When the stator vibrates, the coils in the wire embedding slots 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. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 - 8 As shown in the figure, the present invention is a motor stator wire embedding electric controllable operating platform, including an operating platform 1. Six first supports 11 are fixedly connected to the top of the operating platform 1. Two second supports 13 are fixedly connected to the top of the operating platform 1. Every three of the first supports 11 and one second support 13 are arranged in a rectangle and are symmetrically arranged with the center of the operating platform 1 as the center;

[0035] A support block 15 is fixedly connected to the top of the operating platform 1. A side cover 12 is fixedly connected to the outer wall of the operating platform 1 near the second support 13. Two driving motors 16 are fixedly connected to the inner bottom surface of the operating platform 1. The output ends of the driving motors 16 are fixedly connected with a transmission unit 2. The side of the transmission unit 2 away from the driving motor 16 is fixedly connected with a rotating shaft 17. The rotating shaft 17 is rotatably connected to both the first support 11 and the second support 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;

[0036] The adjustment unit 3 includes a first fixed shaft 31, the first fixed shaft 31 is fixedly connected to the support block 15, an adjustment groove is formed on the outer surface of the first fixed shaft 31, two adjustment outer shells 33 are slidably connected to the surface of the adjustment groove, a rotation hole is formed on the surface of the adjustment outer shell 33 near the top, a driven shaft 362 is rotatably connected in the rotation hole, and an auxiliary driving wheel 37 is fixedly connected to the outer wall of the driven shaft 362.

[0037] In this embodiment, considering that it is relatively difficult to rotate when inserting wires into 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 be detached during rotation. Since it is for inserting wires into 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 is started, the center of gravity of the stator will change due to rotation, and the stator will shake. When the stator shakes, it is also easier to fall off. At the same time, after the stator shakes, the rotation angle will also be inaccurate, and the coils may cross or overlap during wire insertion, resulting in unqualified products.

[0038] 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 adjustment outer shells 33, the auxiliary driving wheel 37 can be brought into contact with the outer surface of the stator to support and limit the stator. At this time, the auxiliary driving wheel 37 and the roller 18 form a triangle, having good support.

[0039] When the stator needs to be rotated, start the driving motor 16, and the rotating shaft 17 is rotated through the transmission unit 2. When the rotating shaft 17 rotates, it will drive the roller 18 to rotate. Since the stator is in contact with the surface of the roller 18, the stator will rotate due to the frictional force between the stator and the roller 18.

[0040] The auxiliary driving wheel 37 can reduce the resistance when the stator rotates, avoid power loss caused by the sliding friction of the traditional limiting plate or limiting block, prevent the angle from changing, avoid coil positioning errors caused by incorrect angles, thereby avoiding wrong slot wire insertion, preventing electromagnetic force imbalance during wrong slot wire 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.

[0041] Specifically, a plurality of limiting shafts 332 are fixedly connected to the middle of the adjustment outer shell 33, a second fixed shaft 331 and two third fixed shafts 341 are fixedly connected to the inner surface of the adjustment outer shell 33 near the bottom, the second fixed shaft 331 is located below the third fixed shaft 341, and a driving shaft 361 is rotatably connected between the third fixed shafts 341.

[0042] The adjusting unit 3 further includes a rotating gear 32, which is fixedly connected to the roller 18, rotatably connected to the inner surface of the first fixed shaft 31, meshed with two first gears 34, the first gears 34 are rotatably connected to the second fixed shafts 331 respectively, the first gears 34 are meshed with second gears 35 respectively, the middle of the second gears 35 is fixedly connected to the driving shaft 361, and the outer wall of the driving shaft 361 is symmetrically connected to a second transmission belt 36 in a transmission manner; the side of the second transmission belt 36 away from the driving shaft 361 is connected to the driven shaft 362 in a transmission manner.

[0043] 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.

[0044] When the auxiliary wheel 37 contacts the stator, through the setting of the rotating gear 32, the rotation of the roller 18 can drive the rotation of the rotating gear 32, and when the rotating gear 32 rotates, it can drive the first gears 34 to rotate. When the first gears 34 rotate, the second gears 35 will rotate synchronously. Since the rotation direction of the rotating gear 32 is the same as that of the roller 18, but the direction will be reversed through the first gears 34, the second gears 35 are needed to restore the direction. When the second gears 35 rotate, they will drive the driving shaft 361 to rotate. When the driving shaft 361 rotates, it will transmit the power to the driven shaft 362 through the second transmission belt 36 and make the driven shaft 362 rotate. When the driven shaft 362 rotates, it will drive the auxiliary wheel 37 to rotate. Since the auxiliary wheel 37 and the roller 18 form a triangle at this time, while increasing the contact area, the power can be fully utilized. At this time, the auxiliary wheel 37 and the roller 18 can push the stator to rotate synchronously. Thus, not only can the waste of power be prevented, but also the movements of the auxiliary wheel 37 and the roller 18 can be synchronized, 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. Therefore, it can prevent the auxiliary wheel 37 from rotating due to the shaking and other movements of the stator when there is no need to rotate, thereby preventing the angle of the stator from changing.

[0045] Specifically, first springs 38 are fixedly connected to the adjacent side surfaces of the adjusting housing 33.

[0046] In this embodiment, considering that when inserting wires into stators of different sizes, the adjustment housing 33 needs to be adjusted at different angles. Since the position of the first fixed shaft 31 is fixed and the maximum angle of the adjustment slot 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. When 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 slots, when the auxiliary driving wheel 37 passes through the slots, the first spring 38 will contract and make the auxiliary driving wheel 37 fit the slots. Since the size of the slots 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 insertion slots can fill the gaps between them, reducing the process of shaping the coils. Thus, when driving the slot wedges into the closed slot openings, reshaping is not required again, saving the process and increasing the production efficiency.

[0047] 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.

[0048] In this embodiment, considering that when the equipment rotates the stator, it needs to rotate a fixed angle. At this time, the rotation speed is slow and the angle is small. In the prior art, the rotation angle is usually not restricted. When inserting wires, if the start switch is accidentally touched or the foot pedal 14 is accidentally stepped on, 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 insertion slot to be damaged due to the friction of the coil. When using the motor, safety problems such as electric leakage breakdown may occur.

[0049] 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 during rotation, thereby reducing the rotation speed. Moreover, 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 transmit the power 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 difficulty of coil installation caused by excessive rotation angle of the stator due to stepless rotation. At the same time, by replacing the half gears 21 of 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 rotate to the coil installation position, reducing the time required for repeatedly adjusting the stator angle.

[0050] Specifically, the limiting unit 4 includes a ratchet wheel 44 and a fixing block 41. One end of the rotating shaft 17 close to the side cover 12 is fixedly connected to the ratchet wheel 44; the inner top surface of the side cover 12 is fixedly connected to the fixing block 41. A plurality of limiting holes are formed at the bottom of the fixing block 41. A limiting rod 43 is slidably connected in the limiting holes. A second spring 42 is fixedly connected between the inner top surface of the limiting holes and the limiting rod 43. The limiting rod 43 is in sliding contact with the ratchet wheel 44.

[0051] In this embodiment, considering that when the equipment is in use, the stator may slide down due to the fact that the other side position is not completely fixed, which will 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 misaligned 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 driving motor 16 to rotate. Considering that some of the existing driving motors 16 do not have reverse protection, it may cause the driving motor 16 to reverse and be damaged;

[0052] 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 be stuck 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 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.

[0053] Specifically, a plurality of gas 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 gas storage tank 19. The air outlet pipe 191 penetrates through the top of the operation platform 1, and the part of the air outlet pipe 191 located at the top of the operation platform 1 is a corrugated pipe.

[0054] 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 wire to adhere to oil stains or be scratched by impurities, and at this time, the wire may leak electricity, resulting in safety problems.

[0055] When there are impurities or oil stains in the wire embedding groove, the gas in the gas 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 groove, the auxiliary driving wheel 37 can repeatedly impact to cause the stator to vibrate, and the impurities can be loosened through the vibration, and then they can be blown away from the stator by high-pressure gas. When the impurities above the stator are vibrated, they can also be blown away by high-pressure gas when they are about to contact the bottom of the stator.

[0056] Specifically, the auxiliary driving wheel 37 is made of a flexible material.

[0057] In this embodiment, considering that the auxiliary driving wheel 37 will repeatedly collide with the stator; 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, thereby avoiding deformation of the stator caused by the repeated impact of the auxiliary driving wheel 37 on the stator. At the same time, because it is a flexible material, the auxiliary driving wheel 37 will bounce multiple times after colliding with the stator, and the impact frequency of the auxiliary driving wheel 37 will be increased. Therefore, not only can the impurities fall off more quickly, but also the installed coils can fill the gaps faster.

[0058] Specifically, a flexible pad 181 is fixedly connected to the outer wall of the roller 18.

[0059] In this embodiment, the setting of the flexible pad 181 can not only increase the friction force between the roller 18 and the stator, but also increase the contact area between the roller 18 and the stator, so that the power can be better transmitted, and it can further prevent the stator from rotating during wire embedding.

[0060] During use,

[0061] First of all, before wire embedding, by replacing the half gears 21 of different specifications, the rotation angle can be changed. Therefore, when processing stators of different sizes, the half gears 21 can be replaced, and each rotation can be rotated to the installation position of the coil, reducing the time required for repeatedly adjusting the stator angle.

[0062] When placing the stator, first place the stator between two rollers 18 by a crane and support it by the rollers 18. At this time, by adjusting the angle between the adjusting housings 33, the auxiliary driving wheel 37 can be brought into contact with the outer surface of the stator to support and limit the stator. At this time, the auxiliary driving wheel 37 and the rollers 18 form a triangle, having good supportability.

[0063] When it is necessary to rotate the stator, start the driving motor 16, and the rotating shaft 17 rotates through the transmission unit 2. When the rotating shaft 17 rotates, it drives the rollers 18 to rotate. Since the stator is in contact with the surface of the rollers 18, the stator rotates due to the frictional force between the stator and the rollers 18.

[0064] 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, 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 drives the first transmission belt 24 to transmit power, and transmits the power 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, so that the rollers 18 drive the stator to rotate, and the rollers 18 can rotate intermittently through the half gear 21, so that the stator can rotate at a fixed angle, avoiding the stator rotating too much due to stepless rotation, which makes it difficult to install the coil.

[0065] The auxiliary driving 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 life.

[0066] The setting of the flexible pad 181 can not only increase the frictional force between the roller 18 and the stator, increase the contact area between the roller 18 and the stator, enable better power transmission, but also further prevent the stator from rotating during wire insertion.

[0067] Secondly, when the auxiliary wheel 37 is in contact with the stator, the setting of the rotating gear 32 can drive the rotation of the rotating gear 32 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 is 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 needed to restore the direction. When the second gear 35 rotates, it drives the driving shaft 361 to rotate. When the driving shaft 361 rotates, it transmits power to the driven shaft 362 through the second transmission belt 36, and the driven shaft 362 is driven by the second transmission belt 36. 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 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 driven to rotate by the auxiliary wheel 37 and the roller 18, thereby preventing power from being wasted and synchronizing 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 prevents the auxiliary wheel 37 from rotating due to the shaking of the stator when it does not need to rotate, thereby preventing the angle of the stator from changing.

[0068] Since the position of the first fixed shaft 31 is fixed and the maximum angle of the adjustment slot is also fixed, the first spring 38 can be set to stretch when the adjustment housing 33 clamps the stator. At this time, the adjustment housing 33 and the auxiliary wheel 37 can adjust the angle automatically according to the size of the stator, thereby adapting 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 is slotted, the first spring 38 will shrink when the auxiliary wheel 37 passes through the slot and make the auxiliary wheel 37 fit the slot. Since the size of the slot is small and the number of slots 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-embedded slots can fill the gaps between them, reducing the process of shaping the coils. Therefore, 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.

[0069] By using a flexible material for the auxiliary wheel 37, the rigid contact between the auxiliary wheel 37 and the stator can be changed to a flexible contact, thereby preventing the auxiliary wheel 37 from repeatedly hitting the stator and causing deformation of the stator. At the same time, because it is a flexible material, the auxiliary wheel 37 will bounce multiple times after colliding with the stator, and the impact frequency of the auxiliary wheel 37 will be increased, which not only allows impurities to fall off more quickly, but also allows the installed coil to fill the gap more quickly.

[0070] Finally, 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 limit rod 43 will catch 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;

[0071] 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 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.
