Description

Technical Field

[0001] The invention relates to the technical field of coil winding, and in particular to a coil winding processing device and a winding process for processing a motor stator. Background Art

[0002] The existing motor coil winding device generally places the motor stator on a platform that can rotate axially, allows the winding device to move up and down around the winding tube of the motor stator, and the rotating platform drives the motor stator to rotate axially back and forth. The winding production of the motor coil is realized through the cooperation of the two. In this process, because only a single winding device is working, the winding efficiency still has room for improvement. Secondly, because both of them will move during the winding process, the copper wire often cannot fit the motor stator well during the winding process, affecting the effect of the motor coil.

[0003] Chinese patent CN117277711B discloses an automatic winding device for a motor coil, comprising: a base; a rotating frame, the rotating frame is rotatably arranged on the base, the rotating frame is used to clamp the two end faces of the motor stator, a plurality of winding posts are evenly arranged on the circumference of the motor stator, the rotating frame drives the motor stator to rotate around an axis direction perpendicular to the motor stator; a winding mechanism, the winding mechanism comprises two winding tubes, the two winding tubes are horizontally spaced, copper wires are passed through the two winding tubes, the copper wires pass through the ends of the two winding tubes and fit on the winding posts; a telescopic rod, the telescopic rod is located on the rotating frame, the telescopic rod is extended to press the copper wire on the winding post.

[0004] Although the above scheme improves the efficiency of winding, it is unable to monitor the fit of the copper wire in real time. As a result, it is impossible to make timely adjustments to the copper wire during the winding process according to its actual fit. The fit between the copper wire and the stator will directly affect the subsequent working conditions of the motor. If one blindly pursues fit, the copper wire and the stator will be wound too tightly, and the copper wire will break during winding. Summary of the invention

[0005] In view of the above problems, a coil winding processing device and a winding process for motor stator processing are provided. When in use, the copper wire in the pay-off unit is first pulled to the stator, and then the copper wire at the pulling position is kept in a stationary state, that is, the pay-off unit is locked at this time, and the copper wire cannot be paid out through the pay-off unit. At this time, the copper wire passing through the winding frame will first pass through the limiting wheel on one side of the guide unit, and then pass from the upper part of the guide unit and extend downward from the other side of the guide unit to the winding position of the stator. In this way, the copper wire needs to contact the limiting wheel and the guide unit respectively after passing through the winding frame. The traditional winding device also has a guide unit. and a limiting wheel, but the traditional limiting wheel is fixed to the base, so the distance between the two limiting wheels in the traditional winding device is always fixed, and the pressure of the copper wire cannot be adjusted according to needs. In order to overcome the above disadvantages, the two limiting wheels are set to be able to move synchronously along the width direction of the base, and the two limiting wheels can move closer to or away from each other when moving. The guiding unit is a triangular structure, and one corner of the triangular structure of the guiding unit is horizontally facing the placement unit, and the corner of the guiding unit facing the placement unit is not solid. When the stator on the placement unit is winding, it moves from the guiding unit to one side of the placement unit. The winding frame is inserted into a corner, so that the copper wire guided by the guide unit can be smoothly wound on the winding part of the stator. Before winding, the winding frame is first rotated around the axis of the winding frame, and the rotation speed is low at this time. The specific rotation speed needs to be set according to the actual production situation, and the rotation angle of the winding frame is less than 30 degrees at this time, otherwise it is easy to cause the rotation angle to be too large, and then the copper wire will be broken. With the rotation of the winding frame, and the copper wire is at a stationary state at the end of the stator, and the wire-releasing unit is also in a locked state, the pressing force of the winding frame on the copper wire will gradually increase after rotation, and the pressure monitoring unit can monitor the actual pressure. The force gradually increases. When the actual pressure on the copper wire reaches the rated winding pressure threshold, the pay-off unit is unlocked and can pay out the copper wire normally. At the same time, the winding frame is increased to the maximum speed. During the winding process, the pressure monitoring unit still monitors the actual pressure of the copper wire in real time to ensure that the pressing force of the winding frame on the copper wire is always within the rated winding pressure threshold. The tightness of the winding frame on the copper wire can directly act on the copper wire winding on the stator. When the pressure on the copper wire is within the rated winding pressure threshold, the copper wire can not only be tightly wound on the stator, but also avoid excessive winding force and subsequent breakage.

When the pressing block rotates, the copper wire rotates around the axis of the winding frame with the pressing block and is wound on the stator. A corrugated sleeve is provided on one side of the pressing block. The two ends of the corrugated sleeve are respectively fixedly connected to the pressing block and one end of the pressing groove. The corrugated sleeve forms a pressure chamber on one side of the pressing block. When the pressing block drives the copper wire to be wound, the pressure chamber is squeezed. The pressure monitoring unit also includes a pressure sensor, which monitors the pressure in the pressure chamber.

[0009] Preferably, the pressure monitoring unit also includes an extension sleeve horizontally arranged on the upper part of the support seat, the extension sleeve is connected with the bellows, a pressure plate is slidably arranged in the extension sleeve along the extension direction of the extension sleeve, a receiving plate is arranged on the side of the pressure plate away from the connection between the extension sleeve and the bellows, the receiving plate is fixedly connected to the inner wall of the extension sleeve, there is a gap between the receiving plate and the pressure plate, a spring is arranged in the gap along the extension direction of the extension sleeve, two ends of the spring are respectively fixedly connected to the pressure plate and the receiving plate, and a pressure sensor is arranged at the connection between the receiving plate and the spring.

[0015] The present invention also relates to a winding process for machining a motor stator, using a coil winding processing device, and the specific steps are as follows:

[0016] S1. When winding the stator just starts, the copper wire in the pay-off unit is passed through the winding frame and pulled to the stator on the placement unit. The winding frame drives the copper wire to rotate to a horizontal state, and then the pay-off unit is locked, and the end of the copper wire pulled to the stator is in a stationary state.

[0017] S2. The winding frame rotates around its own axis. The winding frame generates pressing force on the copper wire when rotating. The copper wire is pressed by the winding frame and is tightly attached to the winding part of the stator. At this time, the actual pressure value monitored by the pressure monitoring unit gradually increases. When the pressure monitoring unit detects that the actual pressure value enters the preset rated winding pressure threshold range, the pay-off unit is unlocked and the winding frame is accelerated to rotate at maximum power.

[0018] S3. During the winding process of the copper wire, the pressure monitoring unit monitors the pressure of the copper wire in real time. When the pressure detected by the pressure monitoring unit is greater than the rated winding pressure threshold, the two limit wheels move away from each other. When the pressure detected by the pressure monitoring unit is less than the rated winding pressure threshold, the two limit wheels move closer to each other.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When in use, first pull the copper wire in the pay-off unit to the stator, and then keep the copper wire in a stationary state, that is, the pay-off unit is locked at this time, and the copper wire cannot be paid out through the pay-off unit. At this time, the copper wire passing through the winding frame will first pass through the limiting wheel on one side of the guide unit, and then pass through the upper part of the guide unit and extend downward from the other side of the guide unit to the winding part of the stator. In this way, the copper wire needs to contact the limiting wheel and the guide unit respectively after passing through the winding frame. The traditional winding device also has a guide unit and a limiting wheel, but the traditional limiting wheel is fixed to the base, so the two limiting wheels in the traditional winding device are fixed to the base. The distance between the two limiting wheels is always fixed, and the pressure of the copper wire cannot be adjusted according to needs. In order to overcome the above disadvantages, the two limiting wheels are set to be able to move synchronously along the width direction of the base, and the two limiting wheels can move closer to or farther away from each other when moving. The guiding unit is a triangular structure, and one corner of the triangular structure of the guiding unit is horizontally facing the placement unit, and the corner of the guiding unit facing the placement unit is not solid. When the stator on the placement unit is wound, it extends from the corner of the guiding unit facing the placement unit. In this way, the copper wire guided by the guiding unit can be smoothly wound on the winding part of the stator. Before winding, first make the winding frame rotate around the axis of the winding frame, and the rotation speed is low at this time. The specific rotation speed needs to be set according to the actual production situation, and the rotation angle of the winding frame is less than 30 degrees at this time, otherwise it is easy to cause the rotation angle to be too large, and then the copper wire will break. As the winding frame rotates, and the copper wire is in a stationary state at the end of the stator, and the pay-off unit is also in a locked state, the pressing force of the winding frame on the copper wire gradually increases after rotation, and the pressure monitoring unit can monitor the actual pressure gradually rising. When the actual pressure on the copper wire reaches the rated winding pressure threshold, the pay-off unit is unlocked. The pay-off unit can pay out the copper wire normally, and the winding frame is increased to the maximum speed. During the winding process, the pressure monitoring unit still monitors the actual pressure of the copper wire in real time to ensure that the pressing force of the winding frame on the copper wire is always within the rated winding pressure threshold. The tightness of the pressure of the copper wire on the winding frame can directly act on the copper wire winding on the stator. When the pressure on the copper wire is within the rated winding dependence threshold, the copper wire can not only be tightly wound on the stator, but also avoid excessive winding force and subsequent breakage. This ensures that the copper wire can be tightly wound on the stator and can also avoid the copper wire from breaking due to excessive winding.

[0021] 2. By arranging a synchronous belt on the guide frame and arranging a bump on the synchronous belt, the friction coefficient between the copper wire and the guide unit is reduced, the wear of the copper wire is reduced, and the breakage of the copper wire during the winding process is avoided.

DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Reference Figure 1 - Figure 3 and Figure 5 - Figure 8 A coil winding processing device comprises a horizontally arranged base 1 and a support base 11 arranged on the base 1, a placement unit 3 for receiving a stator 2 is arranged on one side of the support base 11; a winding unit 4 is arranged on the support base 11, and the winding unit 4 comprises a winding frame 41 horizontally arranged on the support base 11, the winding frame 41 rotates around the horizontal axis of the winding frame 41, a copper wire 21 passes through the winding frame 41, and the copper wire 21 is wound on the stator 2 when the winding frame 41 rotates, and a guide unit 43 is arranged on the side of the winding frame 41 facing the placement unit 3, and the guide unit 43 is used to guide the copper wire 21 to the stator 2 At the winding location, a limiting wheel 42 is respectively provided on both sides of the guide unit 43. The two limiting wheels 42 are arranged along the width direction of the base 1 and move synchronously along the width direction of the base 1. The axis of the limiting wheel 42 is parallel to the vertical direction. A pressure monitoring unit 45 is provided on the winding frame 41. The pressure monitoring unit 45 is used to detect the winding pressure of the copper wire 21 on the winding frame 41, and the pressure monitoring unit 45 is preset with a rated winding pressure threshold. When the actual pressure is greater than the rated winding pressure threshold, the two limiting wheels 42 move away from each other, and when the actual pressure is less than the rated winding pressure threshold, the two limiting wheels 42 move closer to each other.

[0036] In the conventional process, when processing the coil on the stator 2, the copper wire 21 needs to be first wound around the stator 2 by the robot, and then the movement is stopped, and then the winding unit 4 starts to wind the stator 2. However, this method cannot guarantee the winding force during winding, that is, it cannot guarantee that the copper wire 21 can be tightly attached to the stator 2. At the same time, the coil wound on the stator 2 may be too tight, which may cause the copper wire 21 wound on the stator 2 to break. In order to avoid the above situation, the winding is Unit 4 has been improved in design. A driving unit 49 for driving the winding frame 41 to rotate is arranged on the winding frame 41. The driving unit 49 includes a gear ring 491. The gear ring 491 is fixedly mounted on the winding frame 41. A gear 492 is arranged on one side of the gear ring 491. The gear 492 and the gear ring 491 are meshed with each other. A rotation driver 493 is horizontally arranged at the end of the gear 492. The rotation driver 493 is used to drive the gear 492 to rotate. The placement unit 3 is a prior art and will not be repeated here.When in use, the copper wire 21 in the pay-off unit 44 is first pulled to the stator 2, and then the copper wire 21 in the pay-off unit 44 is kept in a stationary state, that is, the pay-off unit 44 is locked at this time, and the copper wire 21 cannot be paid out through the pay-off unit 44. At this time, the copper wire 21 passing through the winding frame 41 will first pass through the limiting wheel 42 on one side of the guide unit 43, and then pass through the upper part of the guide unit 43 and extend downward from the other side of the guide unit 43 to the winding place of the stator 2. In this way, the copper wire 21 needs to contact the limiting wheel 42 and the guide unit 43 respectively after passing through the winding frame 41. The traditional winding device also has a guide unit 43 and a limiting wheel 42, but the traditional limiting wheel 42 and the limiting wheel 42 are The bases 1 are fixed to each other, so that the distance between the two limiting wheels 42 in the traditional winding device is always fixed, and the pressure of the copper wire 21 cannot be adjusted as needed. In order to overcome the above-mentioned disadvantages, the two limiting wheels 42 are set to be able to move synchronously along the width direction of the base 1, and the two limiting wheels 42 can move closer to or farther away from each other when moving. The guide unit 43 is a triangular structure, and one corner of the triangular structure of the guide unit 43 is horizontally facing the placement unit 3, and the corner of the guide unit 43 facing the placement unit 3 is not a solid. The stator 2 located on the placement unit 3 extends from the guide unit 43 toward a corner of one side of the placement unit 3 when winding, so that the guided unit The copper wire 21 guided by 43 can be smoothly wound on the winding part of the stator 2. Before winding, the winding frame 41 is first rotated around the axis of the winding frame 41, and the rotation speed is low at this time. The specific rotation speed needs to be set according to the actual production situation, and the rotation angle of the winding frame 41 is less than 30 degrees at this time, otherwise it is easy to cause the rotation angle to be too large, and then the copper wire 21 will be broken. With the rotation of the winding frame 41, and the copper wire 21 is located at the end of the stator 2 in a stationary state, and the wire-releasing unit 44 is also in a locked state, the pressing force of the winding frame 41 on the copper wire 21 gradually increases after the rotation, and the pressure monitoring unit 45 can monitor the actual pressure gradually increasing. When the When the actual pressure of the copper wire 21 reaches the rated winding pressure threshold, the pay-off unit 44 is unlocked, and the pay-off unit 44 can pay out the copper wire 21 normally. At the same time, the winding frame 41 is increased to the maximum speed. During the winding process, the pressure monitoring unit 45 still monitors the actual pressure of the copper wire 21 in real time to ensure that the pressing force of the winding frame 41 on the copper wire 21 is always within the rated winding pressure threshold. The tightness of the pressure of the winding frame 41 on the copper wire 21 can directly act on the winding of the copper wire 21 on the stator 2. When the pressure on the copper wire 21 is within the rated winding pressure threshold, the copper wire 21 can not only be tightly wound on the stator 2, but also avoid excessive winding force, which may lead to breakage.

[0037] Reference Figure 6 - Figure 8: The orbiting frame 41 is composed of a rotating disk 411 and an extension rod 412. The axis of the rotating disk 411 is horizontally arranged, and the extension rod 412 is fixedly arranged on the peripheral wall of the rotating disk 411. When the rotating disk 411 rotates, it can drive the extension rod 412 to rotate synchronously. The pressing groove 46 is opened on the extension rod 412.

[0038] Reference Figure 8 : The winding frame 41 is provided with a pressing groove 46, which is an arc-shaped structure. A pressing block 47 is provided on the pressing groove 46 and slides along the extension direction of the pressing groove 46. The copper wire 21 that needs to be wound on the stator 2 passes through the pressing block 47. When the pressing block 47 rotates, the copper wire 21 rotates around the axis of the winding frame 41 with the pressing block 47, and the copper wire 21 is wound on the stator 2. A corrugated sleeve 451 is provided on one side of the pressing block 47. The two ends of the corrugated sleeve 451 are respectively fixedly connected to the pressing block 47 and one end of the pressing groove 46. The corrugated sleeve 451 forms a pressure chamber on one side of the pressing block 47. When the pressing block 47 drives the copper wire 21 to be wound, the pressure chamber is squeezed. The pressure monitoring unit 45 also includes a pressure sensor, which monitors the pressure in the pressure chamber.

[0039] The pressing groove 46 is provided on the extension rod 412. Since the copper wire 21 passes through the pressing block 47, when the winding frame 41 rotates, the pressing block 47 slides relative to the pressing groove 46 on the winding frame 41 under the reaction force of the copper wire 21, and the corrugated sleeve 451 located on one side of the pressing block 47 is gradually compressed, and the pressure in the corrugated sleeve 451 gradually increases, so that the pressure sensor can detect the pressure value in the corrugated sleeve 451.

[0040] Reference Fig. 9 The pressure monitoring unit 45 also includes an extension sleeve 452 horizontally arranged on the upper part of the support seat 11, the extension sleeve 452 is connected to the bellows, a pressure plate 453 is slidably arranged in the extension sleeve 452 along the extension direction of the extension sleeve 452, and a receiving plate 454 is arranged on the side of the pressure plate 453 away from the connection between the extension sleeve 452 and the bellows sleeve 451, the receiving plate 454 is fixedly connected to the inner wall of the extension sleeve 452, and there is a gap between the receiving plate 454 and the pressure plate 453, and a spring 455 is arranged in the gap along the extension direction of the extension sleeve 452, and the two ends of the spring 455 are respectively fixedly connected to the pressure plate 453 and the receiving plate 454, and a pressure sensor is arranged at the connection between the receiving plate 454 and the spring 455.

[0041] The pressure monitoring unit 45 also includes a vent pipe 456 and a high-pressure rotating connecting sleeve 457. The high-pressure rotating connecting sleeve 457 is fixedly arranged on the rotating disk 411. The high-pressure rotating connecting sleeve 457 is communicated with the extension sleeve 452. The vent pipe 456 is arranged between the high-pressure rotating connecting sleeve 457 and the corrugated sleeve 451. The corrugated sleeve 451 is communicated with the high-pressure rotating connecting sleeve 457 through the vent pipe 456. When the orbiting frame 41 rotates, the orbiting frame 41 can drive the high-pressure rotating connecting sleeve 457 to rotate synchronously. However, since the high-pressure rotating connecting sleeve 457 itself has a relatively rotating structure, when the high-pressure rotating connecting sleeve 457 is in a relatively rotating state, the high-pressure rotating connecting sleeve 457 is rotated. As the orbiting frame 41 rotates, the extension sleeve 452 will not rotate synchronously with the high-pressure rotating connecting sleeve 457, but will always be fixed on the support seat 11. When the corrugated sleeve 451 is squeezed by the pressing block 47, the air in the corrugated sleeve 451 enters the extension tube through the vent pipe 456 and the high-pressure rotating connecting sleeve 457, and then pushes the pressure plate 453 in the extension tube, so that the pressure plate 453 moves toward the receiving plate 454, so that the spring 455 is compressed, and the elastic force of the spring 455 can act on the pressure sensor of the receiving plate 454, so that the actual pressure of the copper wire 21 can be monitored.

[0042] Reference Figure 6 - Figure 8 The guide unit 43 includes a guide frame 431 with a triangular structure, one corner of the guide frame 431 is horizontally facing the placement unit 3, and a synchronous belt 432 is respectively arranged on the upper and lower sides of the corner of the guide frame 431. The synchronous belt 432 is inclined toward the corner of the guide frame 431, and the outer copper wire 21 of the synchronous belt 432 is in contact, and bumps 4321 are evenly fixed on the outside of the synchronous belt 432. The guide frame 431 rotates in coordination with the orbiting frame 41.

[0043] Each synchronous belt 432 has two synchronous wheels 433, which are arranged along the extension direction of the synchronous belt 432. The synchronous belt 432 is respectively sleeved on the two synchronous wheels 433, and the synchronous wheels 433 cooperate with the synchronous belt 432 in transmission. By setting a protrusion 4321 on the synchronous belt 432, the copper wire 21 can drive the synchronous belt 432 to rotate through the protrusion 4321 when passing through the synchronous belt 432, thereby reducing the friction between the copper wire 21 and the guide unit 43. The traditional guide unit 43 is mostly a triangular structure made of metal. When the winding frame 41 drives the copper wire 21 to rotate, the copper wire 21 will not always be located on the guide unit 43, but with the rotation of the winding frame 41, the copper wire 21 switches back and forth between the upper side and the lower side of the guide unit 43, which easily causes wear between the copper wire 21 and the guide unit 43. This increases the risk of the copper wire 21 breaking.

[0044] Reference Figure 8: The two limiting wheels 42 form a vertical plane in the vertical direction, and the intersection of the vertical plane and the guide unit 43 has a vertical receiving height. When the two limiting wheels 42 move away from each other along the width direction of the base 1, the farthest distance that the two limiting wheels 42 can reach is always less than the vertical receiving height.

[0045] A first slide 421 is provided at the end of the limiting wheel 42 along the width direction of the base 1, and the first slide 421 is used to drive the limiting wheel 42 to move along the width direction of the base 1. The farthest distance that the two limiting wheels 42 can reach is always less than the height of the guide unit 43 in the vertical direction, that is, the height of the intersection of the guide frame 431 and the vertical plane formed by the two limiting wheels 42. In this way, it can be ensured that the copper wire 21 can always alternately contact the upper and lower sides of the guide frame 431 during the rotation of the winding frame 41. Otherwise, the copper wire 21 will only contact the limiting wheel 42 but not the guide frame 431, which will cause the copper wire 21 to fail to be smoothly wound into the stator 2.

[0046] Reference Figure 5 , Figure 6 and Figure 7 : A correction unit 48 is respectively arranged on both sides of the guide frame 431, and the correction unit 48 includes a second slide 481 and a correction plate 482. The second slide 481 is arranged at the upper part of the base 1 along the width direction of the base 1, and the correction plate 482 is arranged at the lower part of the second slide 481. The second slide 481 is used to drive the correction plate 482 to move along the width direction of the base 1. The correction plates 482 in the two correction units 48 move synchronously, and when moving, the two correction plates 482 can approach or move away from each other.

[0047] Since the guide frame 431 and the winding frame 41 are rotatably matched, when the stator 2 is wound, the stator 2 needs to be placed on the placement unit 3 first, and the placement unit 3 can move along the length direction of the base 1. When the stator 2 is placed, the placement unit 3 is located on the side away from the winding frame 41. After the stator 2 is placed, the two correction units 48 are started, and the two correction plates 482 in the two correction units 48 approach each other and correct the guide frame 431 in a tilted state. The placement unit 3 moves toward the side of the winding frame 41, so that the guide frame 431 is in a vertical state. Then the placement unit 3 drives the stator 2 to move toward the guide frame 431. The guide frame 431 is horizontally provided with a receiving groove at the end of a corner of the placement unit 3, and the stator 2 can be inserted into the receiving groove during the movement. At this time, even if the winding frame 41 rotates, the guide frame 431 will no longer rotate.

[0048] Reference Fig. 9 and Fig.10The unwinding unit 44 includes an unwinding drum 441 with a copper wire 21 wound thereon, a support shaft 442 is arranged inside the unwinding drum 441 for supporting the unwinding drum 441, a plurality of rollers 444 are evenly arranged on the support shaft 442 around the axis of the support shaft 442, the rollers 444 are rollingly engaged with the inner ring side wall of the unwinding drum 441, a sliding groove is opened on the side wall of the support shaft 442 along the radial direction of the support shaft 442, an abutment block 443 is slidably arranged in the sliding groove, and an air pump 445 connected to the sliding groove is arranged at the end of the support shaft 442.

[0049] When the air pump 445 inflates the sliding groove, the abutment block 443 extends out. At this time, the unwinding drum 441 is locked, and the copper wire on the unwinding drum 441 cannot be rotated out from the unwinding drum 441. When unlocking is required, the air pump 445 extracts the air in the sliding groove, and the abutment block 443 retracts into the sliding groove. The roller 444 arranged on the support shaft 442 supports the inner ring side wall of the unwinding drum 441. The roller 444 reduces the friction force on the inner wall of the unwinding drum 441, and the unwinding drum 441 can rotate smoothly when unwinding the copper wire 21.

[0050] Reference Figure 4 and Figure 7 : A ratchet 446 is provided at one end of the unwinding drum 441. The ratchet 446 rotates synchronously with the unwinding drum 441 when the unwinding drum 441 is fully sleeved on the supporting shaft 442. A lap rod 447 is provided on one side of the ratchet 446. A coil spring is provided on the rotating end of the lap rod 447. The coil spring provides a pressing force on the lap rod 447 toward the ratchet 446.

[0051] Since the ratchet 446 is unidirectional, the overlapping rod 447 overlapping the ratchet 446 can prevent the ratchet 446 from reversing, thereby preventing the copper wire 21 from being wound too loosely due to the reversal. At the same time, since the ratchet 446 and the overlapping rod 447 directly have a certain friction force, after the winding is stopped, the friction force can prevent the unwinding drum 441 from continuing to rotate due to inertia, that is, the cooperation of the overlapping rod 447 and the ratchet 446 has a deceleration effect on the rotation of the unwinding drum 441, which can prevent the unwinding drum 441 from continuing to rotate after the device stops running, thereby preventing too much copper wire 21 from being released. The wire-releasing unit 44 also includes a traction shell 448. After the copper wire 21 is released from the unwinding drum 441, it needs to be pulled out by the traction shell 448, so that the unwinding direction of the copper wire 21 after being released can be guaranteed.

[0052] Reference Figure 1 - Fig.10 The present invention also relates to a winding process for motor stator processing, using a coil winding processing device, and the specific steps are as follows:

[0053] S1. When winding the stator 2, the copper wire 21 in the pay-off unit 44 passes through the winding frame 41 and is pulled to the stator 2 on the placement unit 3. The winding frame 41 drives the copper wire 21 to rotate to a horizontal state, and then the pay-off unit 44 is locked, and the end of the copper wire 21 pulled to the stator 2 is in a stationary state;

[0054] S2, the winding frame 41 rotates around its own axis, and the winding frame 41 generates a pressing force on the copper wire 21 during the rotation. After the copper wire 21 is pressed by the winding frame 41, it is tightly attached to the winding position of the stator 2. At this time, the actual pressure value monitored by the pressure monitoring unit 45 gradually increases. When the pressure monitoring unit 45 detects that the actual pressure value enters the preset rated winding pressure threshold range, the pay-off unit 44 is unlocked, and the winding frame 41 is accelerated to rotate at maximum power;

[0055] S3. During the winding process of the copper wire 21, the pressure monitoring unit 45 monitors the pressure of the copper wire 21 in real time. When the pressure detected by the pressure monitoring unit 45 is greater than the rated winding pressure threshold, the two limit wheels 42 move away from each other. When the pressure detected by the pressure monitoring unit 45 is less than the rated winding pressure threshold, the two limit wheels 42 move closer to each other.

[0056] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
