Description

Technical Field

[0001] The invention relates to the technical field of motor production, in particular to a winding device for motor production with a tension self-regulating function. Background Art

[0002] Motor stator winding is a core process in motor production, and its quality directly impacts the motor's electromagnetic performance, efficiency, and service life. Traditional winding devices typically use a fixed wire arrangement mechanism, where a mechanical guide rail or stepper motor drives the wire nozzle to reciprocate along the stator slots, achieving layered arrangement of the enameled wire within the stator slots. However, in actual production, the following problems exist:

[0003] Uneven wiring: Manual or mechanical wiring can easily lead to inconsistent gaps between winding layers, overlapping or sparse turns due to operational errors or mechanical rigidity limitations. This uneven wiring can cause uneven magnetic field distribution during motor operation, resulting in torque fluctuations, increased vibration and noise, and reduced energy efficiency.

[0004] Uneven Tension: During the winding process, the tension of the enameled wire must be strictly controlled within a specific range. Too little tension can lead to loose coils and increase the risk of short circuits between turns. Excessive tension can stretch the enameled wire insulation, causing insulation failure or wire diameter thinning, leading to increased resistance. Traditional equipment often uses fixed counterweights or manual tension adjustment, which cannot respond in real time to changes in wire diameter, winding speed fluctuations, or ambient temperature and humidity. This results in poor tension stability and makes it difficult to ensure product consistency.

[0005] The efficiency of switching the circumferential wiring direction is low: the windings of the stator core need to be arranged in multiple slots along the circumference. Traditional equipment needs to be stopped and the wiring direction needs to be manually adjusted when changing slots, resulting in longer production cycles and increased equipment wear.

[0006] While a winding device for generator stator coil production in the prior art (application number: CN202210035887.2) solves the problem of uneven coil distribution, it still fails to address the problems of uneven coil tension and low efficiency in switching the circumferential wiring direction during the winding process.

[0007] Therefore, it is necessary to design a new winding device to solve the problems of uneven tension and low efficiency in switching the circumferential wiring direction. Summary of the Invention

[0008] The object of the present invention is to provide a winding device for motor production with a tension self-adjusting function to solve the problems raised in the prior art.

[0009] To achieve the above object, the present invention provides the following technical solutions:

[0010] A winding device for motor production with a self-adjusting tension function includes a mounting frame, a tension adjusting unit, a wire arranging unit, a switching unit, and a holding unit. The mounting frame is placed on a horizontal ground. The tension adjusting unit is fixedly connected to the mounting frame, the tension adjusting unit is fixedly connected to the wire arranging unit, and the tension adjusting unit is fixedly connected to the holding unit. The tension adjusting unit has the function of adjusting the tension of the coil during the wire transmission process. The switching unit is rotatably connected to the mounting frame, the switching unit is fixedly connected to the holding unit, and the holding unit is fixedly connected to the mounting frame.

[0011] The mounting frame is used to install and fix the tension adjustment unit, the wire arrangement unit, the switching unit and the holding unit. The tension adjustment unit is used to adjust the tension during the coil transportation process. The wire arrangement unit is used for the coil arrangement. The switching unit is used to automatically switch the coil for continuous arrangement of the stator core winding. The holding unit is used to reduce the jitter that occurs during the stator arrangement process. When the wire arrangement unit transports the coil for arrangement, the tension adjustment unit detects the tension of the coil in real time and makes timely adjustments to avoid the impact caused by excessive or insufficient tension. The switching unit is used to continuously arrange the winding of the stator core to improve production efficiency. The holding unit prevents the stator from vibrating during the arrangement process.

[0012] Furthermore, the tension adjustment unit includes a double fixed plate, a rotating plate, a rotating motor, a telescopic motor, a conveying frame and a conveying roller. The double fixed plates are fixedly installed on the mounting frame, the fixed end of the rotating motor is fixedly connected to the double fixed plates through a connecting rod, the output end of the rotating motor is fixedly connected to the rotating plate, the fixed end of the telescopic motor is fixedly connected to the fixed end of the rotating motor, the conveying frame is fixedly installed on the rotating plate, and a plurality of conveying rollers are rotatably installed on the conveying frame.

[0013] Furthermore, the tension adjustment unit includes a retaining cylinder, a retaining frame, a slider, a tension spring, a pull rope and a bent rod. The retaining cylinder is fixedly mounted on an end of the conveying frame away from the rotating motor, the retaining frame is fixedly mounted on a rotating plate, the slider is slidably mounted in the retaining frame, one end of the tension spring is fixedly connected to the retaining frame, the other end of the tension spring is fixedly connected to the slider, one end of the pull rope is fixedly connected to the bent rod, the other end of the pull rope is fixedly connected to the slider, and the bent rod is connected to the conveying frame through a torsion spring.

[0014] Furthermore, the tension adjustment unit also includes a fixed frame, a push rod, an adjustment box, a magnet, an electromagnet, a copper wire and an adjustment roller, the fixed frame is fixedly connected to the bending rod, the adjustment roller is rotatably connected to the fixed frame, one end of the push rod is fixedly connected to the bending rod, and the other end of the push rod is fixedly connected to the magnet, the adjustment box is fixedly installed on the side surface of the conveying frame, the magnet is slidably installed in the adjustment box, the electromagnet is fixedly installed inside the adjustment box, one end of the copper wire bypasses the adjustment roller, and the other end crosses and bypasses multiple conveying rollers and extends from the retaining cylinder, and a thin film pressure sensor is provided on the surface of the adjustment roller.

[0015] When the copper wire is being arranged, the controller controls the rotation motor to start and drive the rotating plate to rotate. Under the action of centrifugal force, on the one hand, the slider slides along the retaining frame toward the outside of the rotating plate while the tension spring is pulled by the slider. On the other hand, the pull rope is reduced by the tension of the slider at this time. The bent rod drives the fixed frame and the adjusting roller to deflect toward the adjusting box under the action of the torsion spring. Under the action of the push rod, the magnetic block slides along the adjusting box toward the electromagnet. At this time, the height of the adjusting roller in the vertical direction increases, increasing the thrust on the copper wire. At this time, the tension of the copper wire increases. After the copper wire is conveyed by the conveying roller on the conveying frame, it is stably conveyed out of the retaining cylinder to avoid shaking of the copper wire during the conveying process, affecting the tightness of the copper wire arrangement. During the copper wire conveying process, if the pressure value of the thin film pressure sensor on the adjusting roller exceeds the preset value, it proves that the copper wire tension is too large at this time. At this time, the controller increases the current supplied to the electromagnet, and the electromagnet is energized to produce a larger polarity, thereby pushing the magnetic block away from the electromagnet. When the actuator slides one end in the opposite direction, the push rod drives the bending rod and the adjusting roller to rotate in the opposite direction, lowering the vertical height of the adjusting roller and thus reducing the tension on the copper wire. This allows for self-regulation of the wire tension. If the electromagnet malfunctions, the controller can also reduce the speed of the telescopic motor. This reduces the centrifugal force of the slider, which, together with the tension spring, increases the tension on the pull rope, pulling the bending rod and the adjusting roller on the fixed frame down vertically, adjusting the wire tension and further ensuring the stability of the device. When the stator winding is about to be completed, the controller reduces the speed of the rotating motor, achieving a reduced speed at the beginning and end of the winding process. As the restoring force of the reduced speed tension spring overcomes the centrifugal force of the slider, the wire tension is reduced at the beginning and end of the process, achieving segmented tension control. Initially, the wire tension is low to ensure smooth wire insertion, then gradually increased to ensure a tight coil, and finally reduced again to prevent overstretching at the end. This dynamic adjustment ensures uniform tension throughout the coil, reducing the risk of deformation and ensuring wire quality.

[0016] Furthermore, the wiring unit includes a fixed platform, a movable plate, a wire laying plate and a memory spring. The fixed platform is fixedly connected to the telescopic end of the telescopic motor, the movable plate is slidably installed on the fixed platform, the wire laying plate is fixedly connected to the movable plate, and both ends of the memory spring are fixedly connected to the wire laying plate.

[0017] As the copper wire rotates with the conveyor rack, the controller controls the telescopic motor to extend and retract periodically. During the extension and retraction stage, it drives the movable plate and the wire laying plate to move forward and backward synchronously to guide the arrangement of the copper wire, ensure the tight arrangement of the copper wire, and improve the slot fill rate. After completing one part of the arrangement, the controller supplies current to the memory spring. After receiving the current, the memory spring expands, driving the movable plates away from each other, releasing the guiding function of the wire laying plate, and preparing for the next part of the arrangement.

[0018] Furthermore, the switching unit includes a stator, a straight cylinder, a rotating table, a cylinder and a sliding column. The stator is fixedly mounted on the straight cylinder, the straight cylinder is fixedly connected to the rotating table, the rotating table is rotatably mounted on the mounting frame, the cylinder is fixedly mounted on the rotating table, and the sliding column is connected to the inside of the cylinder through a buffer spring.

[0019] Furthermore, the switching unit includes a steel rope, a connecting block, a return spring, a support platform and a push plate. The steel rope consists of a multi-end and a single-end. The multi-end end of the steel rope is fixedly connected to the sliding column. The single-end end of the steel rope passes through the mounting frame and is fixedly connected to the retaining unit. The connecting block is fixedly connected to the multi-end end of the steel rope. One end of the return spring is fixedly connected to the connecting block. The other end of the return spring is fixedly connected to the support platform. The push plate is fixedly connected to the retaining unit.

[0020] When the copper wire completes the current winding part and needs to be tangent, the controller controls the first electric push rod and the second electric push rod to retract. The tension on the steel rope is reduced at this time, and the connection block is driven upward by the restoring force of the reset spring. At this time, the slide column slides outward along the cylinder and pushes the slide column to rotate under the action of the push plate. The slide column drives the rotary table to rotate, thereby driving the straight cylinder and the stator to rotate synchronously to arrange the wire at the next part, realizing the rapid tangent effect of the stator. When the switching is completed, the controller controls the first electric push rod and the second electric push rod to retract and extend. On the one hand, under the action of the steel rope, the connection block is pulled toward the support table and the reset spring is compressed. The steel rope pulls the slide column along the cylinder toward the center of the rotary table, thereby avoiding the push plate from causing thrust on the slide column to cause it to deflect.

[0021] Furthermore, the holding unit includes a first electric push rod, a second electric push rod, a slide groove, a slide plate, a column and a holding plate, the fixed end of the first electric push rod is fixedly mounted on the double fixed plates, the output end of the first electric push rod is fixedly connected to the slide plate, the fixed end of the second electric push rod is fixedly mounted on the double fixed plates, the output end of the second electric push rod is fixedly connected to the slide plate, the output end of the first electric push rod is fixedly connected to the push plate, the output end of the first electric push rod is fixedly connected to the steel rope, the slide groove is fixedly mounted on the mounting frame, the push plate is slidably connected to the slide groove, one end of the column is fixedly connected to the slide plate, and the other end of the column is fixedly connected to the holding plate.

[0022] Before stator wiring is arranged, the controller controls the first electric push rod and the second electric push rod to extend, driving the slide plate and the column to move, thereby driving the retaining plate to fit the outer end of the stator winding to maintain the stability of the stator during the wiring process.

[0023] Furthermore, the curvature of the retaining plate and the outer end of the stator winding at the joint is kept consistent.

[0024] In order to ensure that stators of different diameters are closely fitted during the winding process, the plate is kept in close contact to avoid vibration of the stator during the winding process, which may lead to uneven wiring.

[0025] Furthermore, a controller is provided on the mounting frame.

[0026] In order to facilitate the controller to implement automated control of the entire device, save human resources while ensuring the timeliness of the device's response and improving production efficiency.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention controls the rotation motor to start through the controller when the copper wire is being arranged, driving the rotating plate to rotate. Under the action of centrifugal force, on the one hand, the slider slides along the retaining frame toward the outside of the rotating plate while the tension spring is pulled by the slider. On the other hand, the pull rope is reduced by the tension of the slider at this time, and the bent rod drives the fixed frame and the adjusting roller to deflect toward the direction of the adjusting box under the action of the torsion spring. Under the action of the push rod, the magnetic block slides along the adjusting box toward the electromagnet. At this time, the height of the adjusting roller in the vertical direction increases, increasing the thrust on the copper wire. At this time, the tension of the copper wire increases. After the copper wire passes through the conveying roller on the conveying frame, it is stably conveyed out of the retaining cylinder to avoid shaking of the copper wire during the conveying process, which affects the tightness of the copper wire arrangement. During the copper wire conveying process, if the pressure value of the thin film pressure sensor on the adjusting roller exceeds the preset value, it proves that the copper wire tension is too large at this time. At this time, the controller increases the current supplied to the electromagnet, and the electromagnet is energized to generate a larger polarity, thereby pushing the magnetic block away When the electromagnet slides one way, the push rod drives the bending rod and adjusting roller to rotate in the opposite direction, lowering the vertical height of the adjusting roller and thus reducing the tension on the copper wire. This allows for self-regulating wire tension. If the electromagnet malfunctions, the controller can also reduce the speed of the telescopic motor. This reduces the centrifugal force of the slider, which, together with the tension spring, increases the pull on the pull rope. This pulls the bending rod and adjusting roller on the fixed frame down, adjusting the wire tension and further ensuring the stability of the device. When the wire of a single stator winding is about to be laid, the controller slows down the rotating motor speed, achieving slowdown in the initial and final stages of laying. As the slowdown spring's restoring force overcomes the centrifugal force of the slider, the wire tension is reduced at the beginning and end, achieving segmented tension control. Initially, the wire is tensioned at a low level to ensure smooth wire insertion, then gradually increased to ensure a tight coil, and finally reduced again to prevent overstretching at the end. This dynamic adjustment ensures uniform tension across the coil, reducing the risk of deformation and ensuring high-quality laying.

[0029] 2. The present invention controls the telescopic motor to extend and retract periodically by the controller as the copper wire rotates along with the conveyor frame. During the extension and retraction stage, the movable plate and the wire laying plate are driven to move forward and backward synchronously, thereby guiding the arrangement of the copper wire, ensuring the tight arrangement of the copper wire and improving the slot fill rate. After completing one arrangement, the controller supplies current to the memory spring. The memory spring expands after receiving the current, driving the movable plates away from each other, releasing the guiding effect of the wire laying plate, and preparing for the next part of the arrangement.

[0030] 3. The present invention controls the first electric push rod and the second electric push rod to retract when the copper wire completes the current winding part and needs to be tangent. The tension on the steel rope is reduced at this time, and the connection block is driven upward by the restoring force of the reset spring. At this time, the slide column slides outward along the cylinder and is pushed to rotate by the push plate. The slide column drives the rotary table to rotate, thereby driving the straight cylinder and the stator to rotate synchronously to arrange the wire at the next part, thereby achieving a rapid tangent effect of the stator. When the switching is completed, the controller controls the first electric push rod and the second electric push rod to retract and extend. On the one hand, under the action of the steel rope, the connection block is pulled toward the support table and the reset spring is compressed. The steel rope pulls the slide column along the cylinder toward the center of the rotary table, thereby avoiding the push plate from causing thrust on the slide column to cause it to deflect.

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Example: Figures 1-10 As shown, the present invention provides a technical solution:

[0044] like Figure 1 As shown, a winding device for motor production with a tension self-adjusting function includes a mounting frame 1, a tension adjusting unit 2, a wire arranging unit 3, a switching unit 4 and a holding unit 5. The mounting frame 1 is placed on a horizontal ground, the tension adjusting unit 2 is fixedly connected to the mounting frame 1, the tension adjusting unit 2 is fixedly connected to the wire arranging unit 3, the tension adjusting unit 2 is fixedly connected to the holding unit 5, the tension adjusting unit 2 has the function of adjusting the tension of the coil during the wire transmission process, the switching unit 4 is rotatably connected to the mounting frame 1, the switching unit 4 is fixedly connected to the holding unit 5, and the holding unit 5 is fixedly connected to the mounting frame 1.

[0045] The mounting frame 1 is used to install and fix the tension adjustment unit 2, the wire arrangement unit 3, the switching unit 4 and the holding unit 5. The tension adjustment unit 2 is used to adjust the tension during the coil transportation process. The wire arrangement unit 3 is used for the coil arrangement. The switching unit 4 is used to automatically switch the continuous arrangement of the coil in the stator 41 core winding. The holding unit 5 is used to reduce the jitter occurring during the stator 41 wire arrangement process. During the process of the wire arrangement unit 3 conveying the coil for wire arrangement, the tension adjustment unit 2 detects the tension of the coil in real time and adjusts it in time to avoid the influence caused by excessive or insufficient tension. The continuous arrangement of the winding of the stator 41 core is performed through the switching unit 4 to improve production efficiency. The holding unit 5 prevents the stator 41 from vibrating during the wire arrangement process.

[0046] like Figure 2-Figure 5 As shown, the tension adjustment unit 2 includes a double fixed plate 21, a rotating plate 22, a rotating motor 23, a telescopic motor 24, a conveying frame 25 and a conveying roller 26. The double fixed plate 21 is fixedly mounted on the mounting frame 1, the fixed end of the rotating motor 23 is fixedly connected to the double fixed plate 21 through a connecting rod, the output end of the rotating motor 23 is fixedly connected to the rotating plate 22, the fixed end of the telescopic motor 24 is fixedly connected to the fixed end of the rotating motor 23, the conveying frame 25 is fixedly mounted on the rotating plate 22, and a plurality of conveying rollers 26 are rotatably mounted on the conveying frame 25.

[0047] like Figure 3 、 Figure 5 、 Figure 7 As shown, the tension adjustment unit 2 includes a retaining cylinder 27, a retaining frame 28, a slider 29, a tension spring 210, a pull rope 211 and a bent rod 212. The retaining cylinder 27 is fixedly mounted on the end of the conveying frame 25 away from the rotating motor 23, the retaining frame 28 is fixedly mounted on the rotating plate 22, the slider 29 is slidably mounted in the retaining frame 28, one end of the tension spring 210 is fixedly connected to the retaining frame 28, the other end of the tension spring 210 is fixedly connected to the slider 29, one end of the pull rope 211 is fixedly connected to the bent rod 212, the other end of the pull rope 211 is fixedly connected to the slider 29, and the bent rod 212 is connected to the conveying frame 25 through a torsion spring.

[0048] like Figure 3 、 Figure 5 、 Figure 7As shown, the tension adjustment unit 2 also includes a fixed frame 213, a push rod 214, an adjustment box 215, a magnet 216, an electromagnet 217, a copper wire 218 and an adjustment roller 219. The fixed frame 213 is fixedly connected to the bending rod 212, and the adjustment roller 219 is rotatably connected to the fixed frame 213. One end of the push rod 214 is fixedly connected to the bending rod 212, and the other end of the push rod 214 is fixedly connected to the magnet 216. The adjustment box 215 is fixedly installed on the side surface of the conveying frame 25, the magnet 216 is slidably installed in the adjustment box 215, and the electromagnet 217 is fixedly installed inside the adjustment box 215. One end of the copper wire 218 bypasses the adjustment roller 219, and the other end crosses and bypasses multiple conveying rollers 26 and extends from the retaining cylinder 27. A thin film pressure sensor is provided on the surface of the adjustment roller 219.

[0049] When the copper wire 218 is arranged, the controller controls the rotation motor 23 to start, driving the rotating plate 22 to rotate. Under the action of centrifugal force, on the one hand, the slider 29 slides along the retaining frame 28 toward the outside of the rotating plate 22, while the tension spring 210 is pulled by the slider 29. On the other hand, the tension of the pull rope 211 by the slider 29 becomes smaller. Under the action of the torsion spring, the bent rod 212 drives the fixed frame 213 and the adjusting roller 219 to deflect toward the direction of the adjusting box 215. Under the action of the push rod 214, the magnetic block 216 is driven to slide along the adjusting box 215 toward the electromagnet 217. At this time, the adjusting roller 211 is adjusted. 19 is increased in the vertical direction, increasing the thrust on the copper wire 218. At this time, the tension of the copper wire 218 increases. After the copper wire 218 is conveyed by the conveying roller 26 on the conveying frame 25, it is stably conveyed out from the holding cylinder 27 to avoid the copper wire 218 from shaking during the conveying process, which affects the tightness of the copper wire 218. During the conveying process of the copper wire 218, if the pressure value of the film pressure sensor on the adjusting roller 219 exceeds the preset value, it proves that the tension of the copper wire 218 is too large. At this time, the controller increases the conveying current to the electromagnet 217, and the electromagnet 217 is energized to produce a larger polarity. Thus, the magnetic block 216 is pushed away from the electromagnet 217 and slides a distance. Under the action of the push rod 214, the bent rod 212 and the adjusting roller 219 are driven to rotate in the opposite direction, reducing the vertical height of the adjusting roller 219 at this time, thereby reducing the tension on the copper wire 218 at this time, thereby realizing the self-regulating function of the tension of the copper wire 218. If the electromagnet 217 fails, the controller can also reduce the speed of the telescopic motor 24. At this time, the centrifugal force of the slider 29 becomes smaller, and under the action of the spring of the pull rope 211, the pulling force on the pull rope 211 becomes larger, thereby pulling the bent rod 212 and the adjusting roller 219 on the fixed frame 213 to lower The vertical height adjusts the tension of copper wire 218, further ensuring the stability of the device's operation. When the wiring of a single stator winding 41 is about to be completed, the controller reduces the rotation speed of rotary motor 23, achieving reduced speed wiring at the initial and final stages. As the deceleration tension spring 210 overcomes the centrifugal force of slider 29 under its own restoring force, the tension of copper wire 218 decreases during the initial and final stages, achieving segmented tension-controlled wiring. Initially, copper wire 218 maintains a low tension to ensure smooth wire introduction. The tension is gradually increased in the middle stages to ensure a tight coil, and finally reduced again at the end to prevent overstretching at the end. This dynamic adjustment ensures uniform tension throughout the coil, reduces the risk of deformation, and ensures wire quality.

[0050] like Figure 3 As shown, the wiring unit 3 includes a fixed platform 31, a movable plate 32, a wire laying plate 33 and a memory spring 34. The fixed platform 31 is fixedly connected to the telescopic end of the telescopic motor 24, the movable plate 32 is slidably installed on the fixed platform 31, the wire laying plate 33 is fixedly connected to the movable plate 32, and both ends of the memory spring 34 are fixedly connected to the wire laying plate 33.

[0051] As the copper wire 218 rotates with the conveyor rack 25, the controller controls the telescopic motor 24 to extend and retract periodically. During the extension and retraction stage, it drives the movable plate 32 and the wire-laying plate 33 to move forward and backward synchronously, guiding the arrangement of the copper wire 218, ensuring that the copper wire 218 is arranged tightly and improving the slot fill rate. After completing one arrangement, the controller supplies current to the memory spring 34. The memory spring 34 expands after receiving the current, driving the movable plates 32 away from each other, releasing the guiding effect of the wire-laying plate 33, and preparing for the next part of the arrangement.

[0052] like Figure 4 、 Figure 6 、 Figure 10 As shown, the switching unit 4 includes a stator 41, a straight cylinder 42, a rotating table 43, a cylinder 44 and a sliding column 45. The stator 41 is fixedly mounted on the straight cylinder 42, the straight cylinder 42 is fixedly connected to the rotating table 43, the rotating table 43 is rotatably mounted on the mounting frame 1, the cylinder 44 is fixedly mounted on the rotating table 43, and the sliding column 45 is connected to the inside of the cylinder 44 through a buffer spring.

[0053] like Figure 9 、 Figure 10 As shown, the switching unit 4 includes a steel rope 46, a connecting block 47, a return spring 48, a support platform 49 and a push plate 410. The steel rope 46 consists of a multi-head end and a single-head end. The multi-head end of the steel rope 46 is fixedly connected to the sliding column 45, the single-head end of the steel rope 46 passes through the mounting frame 1 and is fixedly connected to the retaining unit 5, the connecting block 47 is fixedly connected to the multi-head end of the steel rope 46, one end of the return spring 48 is fixedly connected to the connecting block 47, the other end of the return spring 48 is fixedly connected to the support platform 49, and the push plate 410 is fixedly connected to the retaining unit 5.

[0054] When the copper wire 218 completes the current winding part and needs to be tangent, the controller controls the first electric push rod 51 and the second electric push rod 52 to retract. The tension on the steel rope 46 is reduced at this time, and the connecting block 47 is driven to move upward under the action of the restoring force of the return spring 48. At this time, the slide post 45 slides outward along the cylinder 44, and the slide post 45 is pushed to rotate under the action of the push plate 410. The slide post 45 drives the rotary table 43 to rotate, thereby driving the straight cylinder 42 and the stator 41 to rotate synchronously to arrange the wire at the next part, thereby achieving a fast tangent effect of the stator 41. When the switching is completed, the controller controls the first electric push rod 51 and the second electric push rod 52 to retract and extend. On the one hand, under the action of the steel rope 46, the connecting block 47 is pulled to move toward the support platform 49 while compressing the return spring 48. The steel rope 46 pulls the slide post 45 to move along the cylinder 44 toward the center of the rotary table 43, thereby avoiding the push plate 410 causing the slide post 45 to be pushed and deflected.

[0055] like Figure 4 、 Figure 8 、 Figure 9As shown, the holding unit 5 includes a first electric push rod 51, a second electric push rod 52, a slide 53, a slide 54, a column 55 and a holding plate 56. The fixed end of the first electric push rod 51 is fixedly installed on the double fixed plate 21, the output end of the first electric push rod 51 is fixedly connected to the slide 54, the fixed end of the second electric push rod 52 is fixedly installed on the double fixed plate 21, the output end of the second electric push rod 52 is fixedly connected to the slide 54, the output end of the first electric push rod 51 is fixedly connected to the push plate 410, the output end of the first electric push rod 51 is fixedly connected to the steel rope 46, the slide 53 is fixedly installed on the mounting frame 1, the push plate 410 is slidably connected to the slide 53, one end of the column 55 is fixedly connected to the slide 54, and the other end of the column 55 is fixedly connected to the holding plate 56.

[0056] Before arranging the stator 41, the controller controls the first electric push rod 51 and the second electric push rod 52 to extend, driving the slide 54 and the column 55 to move, thereby driving the retaining plate 56 to fit the outer end of the stator 41 winding to maintain the stability of the stator 41 during the wiring process.

[0057] like Figure 4 As shown, the curvature of the retaining plate 56 and the outer end of the stator 41 winding at the joint is consistent.

[0058] In order to ensure that the stators 41 of different diameters are closely fitted together by the retaining plate 56 during the winding process, vibration of the stator 41 during the winding process is avoided, thereby preventing uneven wiring.

[0059] like Figure 1 As shown, a controller is provided on the mounting frame 1.

[0060] In order to facilitate the controller to implement automated control of the entire device, save human resources while ensuring the timeliness of the device's response and improving production efficiency.

[0061] Working principle of the present invention:

[0062] When the copper wire 218 is arranged, the controller controls the rotation motor 23 to start, driving the rotating plate 22 to rotate. Under the action of centrifugal force, on the one hand, the slider 29 slides along the retaining frame 28 toward the outside of the rotating plate 22, while the tension spring 210 is pulled by the slider 29. On the other hand, the tension of the pull rope 211 by the slider 29 becomes smaller. Under the action of the torsion spring, the bent rod 212 drives the fixed frame 213 and the adjusting roller 219 to deflect toward the direction of the adjusting box 215. Under the action of the push rod 214, the magnetic block 216 is driven to slide along the adjusting box 215 toward the electromagnet 217. At this time, the adjusting roller 211 is adjusted. 19 is increased in the vertical direction, increasing the thrust on the copper wire 218. At this time, the tension of the copper wire 218 increases. After the copper wire 218 is conveyed by the conveying roller 26 on the conveying frame 25, it is stably conveyed out from the holding cylinder 27 to avoid the copper wire 218 from shaking during the conveying process, which affects the tightness of the copper wire 218. During the conveying process of the copper wire 218, if the pressure value of the film pressure sensor on the adjusting roller 219 exceeds the preset value, it proves that the tension of the copper wire 218 is too large. At this time, the controller increases the conveying current to the electromagnet 217, and the electromagnet 217 is energized to produce a larger polarity. Thus, the magnetic block 216 is pushed away from the electromagnet 217 and slides a distance. Under the action of the push rod 214, the bent rod 212 and the adjusting roller 219 are driven to rotate in the opposite direction, reducing the vertical height of the adjusting roller 219 at this time, thereby reducing the tension on the copper wire 218 at this time, thereby realizing the self-regulating function of the tension of the copper wire 218. If the electromagnet 217 fails, the controller can also reduce the speed of the telescopic motor 24. At this time, the centrifugal force of the slider 29 becomes smaller, and under the action of the spring of the pull rope 211, the pulling force on the pull rope 211 becomes larger, thereby pulling the bent rod 212 and the adjusting roller 219 on the fixed frame 213 to lower The vertical height adjusts the tension of copper wire 218, further ensuring the stability of the device's operation. When the wiring of a single stator winding 41 is about to be completed, the controller reduces the rotation speed of rotary motor 23, achieving reduced speed wiring at the initial and final stages. As the deceleration tension spring 210 overcomes the centrifugal force of slider 29 under its own restoring force, the tension of copper wire 218 decreases during the initial and final stages, achieving segmented tension-controlled wiring. Initially, copper wire 218 maintains a low tension to ensure smooth wire introduction. The tension is gradually increased in the middle stages to ensure a tight coil, and finally reduced again at the end to prevent overstretching at the end. This dynamic adjustment ensures uniform tension throughout the coil, reduces the risk of deformation, and ensures wire quality.

[0063] As the copper wire 218 rotates with the conveyor rack 25, the controller controls the telescopic motor 24 to extend and retract periodically. During the extension and retraction stage, it drives the movable plate 32 and the wire-laying plate 33 to move forward and backward synchronously, guiding the arrangement of the copper wire 218, ensuring that the copper wire 218 is arranged tightly and improving the slot fill rate. After completing one arrangement, the controller supplies current to the memory spring 34. The memory spring 34 expands after receiving the current, driving the movable plates 32 away from each other, releasing the guiding effect of the wire-laying plate 33, and preparing for the next part of the arrangement.

[0064] When the copper wire 218 completes the current winding part and needs to be tangent, the controller controls the first electric push rod 51 and the second electric push rod 52 to retract. The tension on the steel rope 46 is reduced at this time, and the connecting block 47 is driven to move upward under the action of the restoring force of the return spring 48. At this time, the slide post 45 slides outward along the cylinder 44, and the slide post 45 is pushed to rotate under the action of the push plate 410. The slide post 45 drives the rotary table 43 to rotate, thereby driving the straight cylinder 42 and the stator 41 to rotate synchronously to arrange the wire at the next part, thereby achieving a fast tangent effect of the stator 41. When the switching is completed, the controller controls the first electric push rod 51 and the second electric push rod 52 to retract and extend. On the one hand, under the action of the steel rope 46, the connecting block 47 is pulled to move toward the support platform 49 while compressing the return spring 48. The steel rope 46 pulls the slide post 45 to move along the cylinder 44 toward the center of the rotary table 43, thereby avoiding the push plate 410 causing the slide post 45 to be pushed and deflected.

[0065] Before arranging the stator 41, the controller controls the first electric push rod 51 and the second electric push rod 52 to extend, driving the slide 54 and the column 55 to move, thereby driving the retaining plate 56 to fit the outer end of the stator 41 winding to maintain the stability of the stator 41 during the wiring process.
