Description

Technical Field

[0001] This invention belongs to the field of motor manufacturing equipment technology, and particularly relates to a winding device for motor manufacturing. Background Technology

[0002] In the automated production process of motor stator windings, coil winding is a key process that determines the performance and reliability of the motor. Different models and specifications of motors have different numbers of stator slots and poles, resulting in different coil slot pitches. Traditional winding devices often have fixed winding widths or require manual adjustment of the mold size. This adjustment process is cumbersome, has a long debugging cycle, low changeover efficiency, and low precision, which can easily lead to coil size deviations and affect subsequent winding processes. Furthermore, during the winding process, the surface of the winding mold is easily contaminated with dust, metal shavings, and other impurities. Existing devices lack online cleaning functions, and these impurities can scrape the surface of the enameled wire during winding, causing insulation damage, inter-turn short circuit hazards, and consequently affecting the motor's insulation performance and service life. Moreover, existing winding devices generally lack closed-loop tension adjustment functions, relying mainly on manual experience to control the winding tightness. This can easily lead to problems such as coils being wound too loosely, too tightly, or unevenly. Too loose a winding will result in loose coils that are prone to deformation during subsequent winding, while too tight a winding will damage the enameled wire insulation layer, causing inter-turn short circuit hazards and severely affecting the consistency of the stator winding and product yield. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a winding device for motor manufacturing, which realizes the functions of adaptive slot pitch adjustment, closed-loop tension control, and online mold cleaning.

The lower end of the first drive assembly is movably engaged with the lower end of the second drive assembly, and the upper end of the second drive assembly is movably engaged with the upper end of the first drive assembly. The gear is located between the first drive assembly and the second drive assembly and meshes with both of them for transmission. The winding assembly is respectively mounted on the side walls of the first drive assembly and the second drive assembly.

[0005] Further, the first driving assembly includes a driving member, a gear, a connecting plate, and an insert plate. The driving member has a groove at its upper end, the gear is fixedly disposed on the bottom wall of the driving member, the connecting plate is fixedly disposed at the bottom of the end of the driving member away from the groove, and the insert plate is fixedly disposed at the lower end of the connecting plate. The insert plate of the first driving assembly is movably engaged in the groove of the second driving assembly, and the insert plate of the second driving assembly is movably engaged in the groove of the first driving assembly. A first elastic bladder is installed between the insert plate of the second driving assembly and the groove of the first driving assembly, and a second elastic bladder is installed between the insert plate of the first driving assembly and the groove of the second driving assembly. The gears of the first and second driving assemblies mesh with the upper and lower ends of the gear, respectively. When the gear rotates, the gears can drive the first and second driving assemblies to move in directions away from or towards each other.

[0006] The winding assembly includes a connecting box, an arc-shaped fixing plate, an arc-shaped plate, a baffle, and an adjustment component. The connecting box is fixedly installed on the connecting plate. The inner side of the arc-shaped fixing plate is fixedly connected to the connecting box. The arc-shaped plate is movably disposed at both ends of the arc-shaped fixing plate. An adjustment chamber is provided between the arc-shaped plate and the arc-shaped fixing plate. The baffle is fixedly disposed on opposite sides of the arc-shaped fixing plate. The adjustment component is movably installed on the outer side of the arc-shaped fixing plate and located between the baffles.

[0007] The connecting box is internally equipped with a partition, which divides the interior of the connecting box into a first cavity and a second cavity. An upper storage bladder is disposed in the first cavity, and a lower storage bladder is disposed in the second cavity. A first vent pipe is provided inside the driving component, which connects the corresponding elastic bladder to the upper storage bladder. A second vent pipe is provided inside the arc-shaped fixing plate, which is connected to the upper and lower storage bladders via an upper connecting pipe and a lower connecting pipe, respectively. A control valve is provided in both the upper and lower connecting pipes. Both ends of the second vent pipe are connected to the regulating bladders at both ends.

[0008] The adjustment assembly includes a placement plate, a hydraulic rod, a mounting plate, an adjustment plate, a cleaning brush, and bolts. The hydraulic rod is fixedly installed on one side of the baffle. The placement plate is fixedly connected to the movable end of the hydraulic rod. The placement plate has a vertically penetrating placement cavity. The mounting plate is detachably assembled to both ends of the placement cavity by bolts. The adjustment plate is movably snapped onto the mounting plate by bolts. The cleaning brush is detachably disposed at the bottom of the adjustment plate and extends downward out of the placement plate.

[0009] A pressure sensor is installed at the connection point between the control bladder and the arc-shaped fixing plate to detect the pressure inside the control bladder.

[0010] In a preferred embodiment of the present invention, the adjustment drive assembly includes a brake servo motor, a support rod, a turntable, and a plug rod. The motor is mounted on the side wall of the drive disc, the lower end of the support rod is movably mounted on the side wall of the drive disc and is located outside the motor, the turntable is mounted on the upper end of the support rod and its center is connected to the output shaft end of the motor, and the plug rod is mounted on the center of the side wall of the turntable.

[0011] Preferably, the sleeve has a slot that matches the insert rod, and the insert rod is movably inserted through the slot to realize the installation and connection of the winding device and the adjustment drive assembly. The end of the insert rod has a threaded rod and is locked and fixed by a nut. When the winding device is inserted into the insert rod, the threaded rod at the end of the insert rod extends out of the winding device, and the winding device is fixed by the nut.

[0012] In a preferred embodiment of the present invention, the drive disk is provided with a first limiting groove and a second limiting groove, the lower end of the support rod is movably engaged in the second limiting groove, and a limiting rod is movably installed in the first limiting groove.

[0013] The connecting plate has a third limiting groove that matches the limiting rod. The limiting rod moves through the third limiting groove to realize the installation and connection of the winding device and the drive disk. The end of the limiting rod has a threaded rod and is locked and fixed by a nut. When the winding device is inserted into the limiting rod, the threaded rod at the end of the limiting rod extends out of the winding device and is fixed by the nut.

[0014] The beneficial effects of the present invention after adopting the above structure are as follows: (1) This application realizes the slot pitch adaptive adjustment function. By adjusting the drive component to drive the sleeve to rotate, the sleeve drives the gear to rotate, and the gear meshes to drive the first drive component and the second drive component to make linear motion towards or away from each other. The winding width can be adjusted to adapt to motor stator windings with different slot pitches and different specifications. There is no need to frequently change the winding mold, which greatly shortens the changeover and debugging time and improves the equipment production capacity.

[0015] (2) To achieve closed-loop adaptive adjustment of winding tension, the first and second elastic bladders are squeezed by the relative movement of the first and second drive components to generate air pressure, which drives the deformation of the control bladder. Combined with the pressure sensor to detect the pressure inside the control bladder in real time, the winding tension can be judged in real time. When the winding is too loose, the upper storage bladder replenishes air to expand the control bladder and raise the arc plate to tighten the winding. When the winding is too tight, the control bladder exhausts and contracts, and the arc plate is lowered to loosen the winding. This effectively avoids the problem of the coil being too loose or too tight, ensures the consistency of the winding, and reduces the risk of damage to the enameled wire.

[0016] (3) To achieve online cleaning of the winding mold, the hydraulic rod of the component is adjusted to drive the placement plate to move, which in turn drives the cleaning brush to move along the surface of the arc-shaped fixed plate. This can remove dust, metal shavings and other impurities from the mold surface before winding. At the same time, the fit of the cleaning brush can be adjusted by bolts. After cleaning, it can be retracted into the placement plate without affecting the winding operation. This effectively prevents impurities from scratching the enameled wire, protects the insulation layer, and improves the reliability of the stator winding.

[0017] (4) The winding device adopts a detachable assembly structure of sleeve and insert rod, limit rod and third limit groove, which is firmly installed, easy to disassemble and assemble, and facilitates quick replacement of parts and maintenance of equipment. Attached Figure Description

The gear 5 is located between the first drive assembly 6 and the second drive assembly 7 and meshes with both of them for transmission. The winding assembly 8 is installed on the side walls of the first drive assembly 6 and the second drive assembly 7 respectively. It should be noted that the rotation of the sleeve 4 can drive the gear 5 to rotate, thereby driving the first drive assembly 6 and the second drive assembly 7 to move in opposite directions or away in a straight line.

[0024] The first driving assembly 6 includes a driving member 9, a gear condition 10, a connecting plate 11, and a insert plate 12. The driving member 9 has a groove 13 at its upper end. The gear condition 10 is fixedly disposed on the bottom wall of the driving member 9. The connecting plate 11 is fixedly disposed at the bottom of the end of the driving member 9 away from the groove 13. The insert plate 12 is fixedly disposed at the lower end of the connecting plate 11. The insert plate 12 of the first driving assembly 6 is movably engaged within the groove 13 of the second driving assembly 7, and the insert plate 12 of the second driving assembly 7 is movably engaged within the groove 13 of the first driving assembly 6. Within the slide groove 13 of the drive assembly 6, a first elastic bladder 14 is installed between the insert plate 12 of the second drive assembly 7 and the slide groove 13 of the first drive assembly 6, and a second elastic bladder 15 is installed between the insert plate 12 of the first drive assembly 6 and the slide groove 13 of the second drive assembly 7; the tooth conditions 10 of the first drive assembly 6 and the second drive assembly 7 respectively mesh with the upper and lower ends of the gear 5. When the gear 5 rotates, the tooth conditions 10 can push the first drive assembly 6 and the second drive assembly 7 to move away from or towards each other.

[0025] The winding assembly 8 includes a connecting box 16, an arc-shaped fixing plate 17, an arc-shaped plate 18, a baffle 19, and an adjustment assembly 20. The connecting box 16 is fixedly installed on the connecting plate 11. The inner side of the arc-shaped fixing plate 17 is fixedly connected to the connecting box 16. The arc-shaped plate 18 is movably disposed at both ends of the arc-shaped fixing plate 17. An adjustment bladder 21 is disposed between the arc-shaped plate 18 and the arc-shaped fixing plate 17. The baffle 19 is fixedly disposed on opposite sides of the arc-shaped fixing plate 17. The adjustment assembly 20 is movably installed on the outer side of the arc-shaped fixing plate 17 and located between the baffles 19.

[0026] The connecting box 16 is internally provided with a partition 22, which divides the interior of the connecting box 16 into a first cavity 23 and a second cavity 24. An upper storage bladder 25 is provided in the first cavity 23, and a lower storage bladder 26 is provided in the second cavity 24. A first vent pipe 27 is provided inside the driving component 9, which connects the corresponding elastic bladder to the upper storage bladder 25. A second vent pipe 28 is provided inside the arc-shaped fixing plate 17, which is connected to the upper storage bladder 25 and the lower storage bladder 26 through an upper connecting pipe 44 and a lower connecting pipe 45, respectively. A control valve is provided in both the upper connecting pipe 44 and the lower connecting pipe 45. The two ends of the second vent pipe 28 are respectively connected to the regulating bladders 21 at both ends. It should be noted that, in the initial state, the first driving component 6 and the second driving component 7 are in a position far apart from each other. When the first driving component 6 and the second driving component 7 move towards each other, the control valve in the upper connecting pipe 44 opens and the control valve in the lower connecting pipe 45 closes. The insert plate 12 of the first driving component 6 squeezes the first elastic bladder 14, and the insert plate 12 of the second driving component 7 squeezes the second elastic bladder 15. The gas in the elastic bladder enters the upper storage bladder 25 through the corresponding first vent pipe 27. The gas in the upper storage bladder 25 enters the two regulating bladders 21 through the second vent pipe 28. The regulating bladders 21 expand and drive the arc plate 18 to rise slightly. Then the control valve of the upper connecting pipe 44 closes. The first driving component 6 and the second driving component 7 continue to move towards each other, and the upper storage bladder 25 expands under pressure, and the internal air pressure continues to rise.

[0027] The adjustment assembly 20 includes a placement plate 29, a hydraulic rod 30, a mounting plate 31, an adjustment plate 32, a cleaning brush 33, and bolts 34. The hydraulic rod 30 is fixedly installed on one side of the baffle 19. The placement plate 29 is fixedly connected to the movable end of the hydraulic rod 30. The placement plate 29 has a vertically penetrating placement cavity 35. The mounting plate 31 is detachably assembled to both ends of the placement cavity 35 by bolts 34. The adjustment plate 32 is movably snapped onto the mounting plate 31 by bolts 34. The cleaning brush 33 is detachably disposed at the bottom of the adjustment plate 32 and extends downward out of the placement plate 29. It should be noted that tightening the locking bolt 34 can adjust the vertical position of the adjusting plate 32 within the placement cavity 35, thereby adjusting the fit between the cleaning brush 33 and the outer wall of the arc-shaped fixing plate 17; the hydraulic rod 30 drives the placement plate 29 to move along the outer wall of the arc-shaped fixing plate 17, causing the cleaning brush 33 to clean the surface of the arc-shaped fixing plate 17 online, removing impurities and preventing damage to the insulation layer of the enameled wire; after cleaning, tightening the bolt 34 in the opposite direction causes the cleaning brush 33 to retract into the placement plate 29, and the hydraulic rod 30 resets the placement plate 29, so that the distance between the placement plate 29 and the baffle 19 on the other side meets the requirements of the winding process; the adjusting plate 32 and the cleaning brush 33 can be quickly replaced by removing the locking bolt 34.

[0028] A pressure sensor is installed at the connection position between the regulating bladder 21 and the arc-shaped fixing plate 17 to detect the pressure inside the regulating bladder 21. During the winding of the enameled wire, if the pressure sensor reading is too low, it is determined that the winding is loose, the upper connecting pipe 44 controls the valve to open, and the gas in the upper storage bladder 25 enters the regulating bladder 21. The regulating bladder 21 expands and lifts the arc-shaped plate 18, tightening the winding. If the pressure sensor reading is too high, it is determined that the winding is too tight, the lower connecting pipe 45 controls the valve to open, and the gas in the regulating bladder 21 flows back to the lower storage bladder 26. The regulating bladder 21 contracts and drives the arc-shaped plate 18 to lower, loosening the winding and realizing closed-loop adaptive adjustment of the winding tension.

[0029] The adjustment drive assembly 2 includes a brake servo motor 36, a support rod 37, a turntable 38, and a plug rod 39. The motor is mounted on the side wall of the drive disk 1. The lower end of the support rod 37 is movably mounted on the side wall of the drive disk 1 and is located outside the motor. The turntable 38 is mounted on the upper end of the support rod 37 and its center is connected to the output shaft end of the motor. The plug rod 39 is mounted on the center of the side wall of the turntable 38. The brake servo motor 36 has a built-in power-off electromagnetic brake. When energized, the brake is released; when de-energized, the brake locks the output shaft.

[0030] The sleeve 4 has a slot 40 that matches the insertion rod 39. The insertion rod 39 is movably inserted through the slot 40 to realize the installation and connection of the winding device 3 and the adjustment drive assembly 2. The end of the insertion rod 39 has a threaded rod and is locked and fixed by a nut. When the winding device 3 is inserted into the insertion rod 39, the threaded rod at the end of the insertion rod 39 extends out of the winding device 3 and is fixed by the nut. When the insertion rod 39 rotates, it can drive the sleeve 4 to rotate, and the sleeve 4 drives the gear 5 to rotate.

[0031] The drive disk 1 has a first limiting groove 41 and a second limiting groove 42. The lower end of the support rod 37 is movably engaged in the second limiting groove 42, and a limiting rod 43 is movably installed in the first limiting groove 41.

[0032] The connecting plate 11 has a third limiting groove 46 that matches the limiting rod 43. The limiting rod 43 is movably inserted through the third limiting groove 46 to realize the installation and connection of the winding device 3 and the drive disk 1. The end of the limiting rod 43 is provided with a threaded rod and is locked and fixed by a nut. When the winding device 3 is inserted into the limiting rod 43, the threaded rod at the end of the limiting rod 43 extends out of the winding device 3 and is fixed by the nut. The external drive drives the drive disk 1 to rotate, and the drive disk 1 drives the winding device 3 and the adjustment drive assembly 2 to rotate.

[0033] The specific usage is as follows: The winding device 3 is engaged with the insertion rod 39 of the adjustment drive assembly 2 through the sleeve 4, and at the same time, the third limiting groove 46 on the connecting plate 11 is inserted and positioned with the limiting rod 43 of the drive plate 1, and then locked with the end nut to complete the fixed assembly of the winding device 3.

[0034] Then, according to the slot pitch and size requirements of the coil to be wound, the slot pitch is adjusted, the brake servo motor 36 is started, the brake is released after the motor is powered on, the output shaft drives the turntable 38 and the insertion rod 39 to rotate, and the insertion rod 39 drives the sleeve 4 and the gear 5 to rotate synchronously; the gear 5 meshes and drives the first drive assembly 6 and the second drive assembly 7 to move in opposite directions, adjusting to the target winding width to match the slot pitch requirements of the coil to be wound, and then the brake servo motor 36 is turned off. After the motor is powered off, the brake locks the output shaft to maintain a stable position.

[0035] Adjust the bolts 34 of the adjusting assembly 20 so that the cleaning brush 33 extends out and fits against the surface of the arc-shaped fixing plate 17. Then, start the hydraulic rod 30. The hydraulic rod 30 drives the placement plate 29 to move along the outer wall of the arc-shaped fixing plate 17, which drives the cleaning brush 33 to thoroughly clean the mold surface and remove dust, metal shavings and other impurities. After cleaning, turn the bolts 34 in the opposite direction to retract the cleaning brush 33 into the placement plate 29. The hydraulic rod 30 resets the placement plate 29 so that the distance between the placement plate 29 and the baffle 19 on the other side meets the requirements of the winding process.

[0036] An external drive mechanism drives the drive disc 1 to rotate, and the winding device 3 revolves with the drive disc 1 to complete the winding operation of the enameled wire on the arc-shaped fixed plate 17 and the arc-shaped plate 18. During the winding process, the pressure sensor monitors the pressure in the control bladder 21 in real time and dynamically adjusts the winding tension: if the detected pressure value is too low, it is determined that the winding is loose, the upper connecting pipe 44 control valve opens, the gas in the upper storage bladder 25 enters the control bladder 21, the control bladder 21 expands and lifts the arc-shaped plate 18, and tensions the winding; if the detected pressure value is too high, it is determined that the winding is too tight, the lower connecting pipe 45 control valve opens, the gas in the control bladder 21 flows back to the lower storage bladder 26, the control bladder 21 contracts and drives the arc-shaped plate 18 to adjust downward, and loosens the winding.

[0037] After winding is completed, the rotation is stopped, the wound enameled wire is bundled, and then the first drive assembly 6 and the second drive assembly 7 move towards each other under the drive of the servo motor to remove the bundled enameled wire from the winding device 3.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
