Description

Technical Field

[0001] This application relates to the technical field of motor manufacturing equipment, and in particular to a fully automatic motor winding device. Background Technology

[0002] For small motors, the copper wire windings on the stator or rotor are a core component. As a conductive material, copper wire generates an induced magnetic field when energized, realizing the conversion between electrical energy and mechanical energy. The precision, uniformity, and consistency of its winding directly affect the motor's performance efficiency, output power, and operational stability.

[0003] In the manufacturing process of small motors, winding copper wire onto the rotor is a crucial step. However, most motor winding devices on the market are semi-automated, still relying heavily on manual labor in actual operation. For example, workers must manually crank winding claws to wind the copper wire onto the rotor. During the winding process, operators must also continuously adjust the rotor's deflection angle manually to wind the copper wire in batches and layers at different locations. This frequent manual operation not only increases the workload of operators but also slows down the production process, resulting in low overall production efficiency. Utility Model Content

[0004] To address the problems of low production efficiency and high labor intensity for operators caused by reliance on manual operation during rotor winding, this application provides a fully automatic motor winding device.

[0005] An automatic motor winding device includes a support box, a wire spool, a winding assembly, and a deflection assembly. The winding assembly includes a winding motor and a driven shaft, both connected to the support box. The winding motor drives the driven shaft to rotate. A winding claw is connected to the driven shaft, and a winding guide wheel is connected to the winding claw. The wire spool is mounted on the support box, and the copper wire on the spool is wound and supported on the winding guide wheel. The winding claw winds the copper wire on the winding guide wheel onto a rotor. The deflection assembly includes a deflection motor, which is vertically mounted on the support box. A positioning hole is provided at the end of the output shaft of the deflection motor for rotor positioning. The deflection motor drives the rotor to deflect at a certain angle, thereby winding the copper wire onto the rotor in batches.

[0006] By adopting the above technical solution, the driven shaft is driven to rotate by the winding motor, and the driven shaft drives the winding claw and the winding lead wheel to rotate, so that the copper wire is automatically and continuously wound in the winding slot of the rotor; the deflection motor drives the rotor to deflect at a set angle through the positioning hole at the end of the output shaft, so that the copper wire is wound in batches at different winding slot positions, thereby improving the winding uniformity.

[0007] Preferably, a pushing assembly is connected to the support box. The pushing assembly includes a pushing cylinder and a pushing plate. The pushing cylinder is connected to the support box, and the end of the piston rod of the pushing cylinder is connected to the pushing plate. The winding motor and the driven shaft are both connected to the pushing plate. A guide block is connected to the driven shaft. The pushing cylinder drives the guide block to move toward the rotor through the pushing plate and the driven shaft. The guide block is used to guide the copper wire on the winding lead wheel to the rotor.

[0008] By adopting the above technical solution, the cylinder drives the push plate to move horizontally, thereby causing the driven shaft and guide block mounted on the push plate to move closer to or away from the rotor as a whole; the guide block is used to accurately guide the copper wire on the winding claw into the winding slot, reducing manual wire guiding operations.

[0009] Preferably, a drive pulley is connected to the output shaft of the wound motor, the wound motor is located on the driven shaft side, a driven pulley is connected to the driven shaft, and the drive pulley is connected to the driven pulley via a drive belt.

[0010] By adopting the above technical solution, the output shaft of the winding motor drives the driven pulleys on multiple driven shafts to rotate synchronously through the drive pulley and drive belt, ensuring that all winding claws rotate simultaneously, in the same direction, and at the same speed, thereby improving the winding efficiency and consistency of multi-station winding.

[0011] Preferably, both the drive pulley and the driven pulley are synchronous pulleys, and the drive belt is a synchronous toothed belt.

[0012] By adopting the above technical solution, the drive pulley and the driven pulley adopt a synchronous pulley structure, and the drive belt is selected as a synchronous toothed belt. There is no slippage during the transmission process, which ensures the stable speed of the winding claw.

[0013] Preferably, the deflection assembly further includes a telescopic motor, a sleeve, and a positioning wedge. A mounting plate is coaxially connected to the output shaft of the deflection motor, and the telescopic motor is vertically connected to the mounting plate. The sleeve is fitted onto the output shaft of the deflection motor, and a positioning wedge is vertically connected to the outer wall of the sleeve. The sleeve is connected to the telescopic shaft of the telescopic motor via a connecting block. The telescopic motor drives the positioning wedge to position the rotor through the sleeve.

[0014] By adopting the above technical solution, the telescopic motor drives the sleeve to move up and down along the output shaft of the deflection motor through the connecting block, which drives the positioning wedge fixed on the outside of the sleeve to insert or exit the rotor winding slot, thereby achieving circumferential positioning of the rotor winding position and preventing deflection during the winding process.

[0015] Preferably, a positioning mechanism is connected to the support box. The positioning mechanism includes a lifting assembly, which includes a lifting cylinder, a lifting support frame, and a lifting plate. The lifting support frame is vertically connected to the support box, and the lifting plate is slidably connected to the lifting support frame. The lifting cylinder is vertically connected to the support box, and the end of the piston rod of the lifting cylinder is connected to the lifting plate. A positioning support rod is vertically connected to the bottom wall of the lifting plate, and a positioning cylinder is connected to the lower end of the positioning support rod. The positioning cylinder is located above the rotor. The lifting cylinder drives the positioning cylinder to position the rotor through the lifting plate.

[0016] By adopting the above technical solution, the lifting cylinder drives the lifting plate to move vertically along the lifting support frame, which in turn drives the positioning support rod and positioning cylinder fixed at the bottom of the lifting plate to press down on the top of the rotor, thereby fixing the rotor axially and preventing the motor from moving up and down during winding.

[0017] Preferably, the positioning mechanism further includes a mounting rod and a transverse positioning cylinder. The mounting rod is vertically connected to the support box, and the transverse positioning cylinder is connected to the mounting rod. The transverse positioning cylinder is located on one side of the rotor, and a positioning block is connected to the piston rod of the transverse positioning cylinder. The transverse positioning cylinder drives the positioning block to position the rotor through the piston rod.

[0018] By adopting the above technical solution, the transverse positioning cylinder pushes the positioning block horizontally against the outer wall of the rotor through the piston rod, thereby achieving radial auxiliary positioning of the rotor.

[0019] Preferably, the support box is further connected to a wire breaking assembly, which includes a movable cylinder connected to the top wall of the lifting plate. One end of the movable cylinder is connected to a vertical connecting rod, and the lower end of the vertical connecting rod is connected to a wire breaking cylinder. The wire breaking cylinder is located on one side of the winding claw, and a clamping block is connected to the piston rod of the wire breaking cylinder. The wire breaking cylinder is used to clamp the copper wire on the winding claw, thus achieving wire hanging before the rotor is wound with copper wire. The movable cylinder drives the wire breaking cylinder and the clamping block to move through the vertical connecting rod, so as to break the clamped copper wire, thus achieving wire breaking after the rotor has finished winding copper wire.

[0020] By adopting the above technical solution, the wire-breaking cylinder clamps the copper wire led out by the winding lead wheel through the clamping block at the end of the piston rod; the moving cylinder drives the wire-breaking cylinder to move horizontally through the vertical connecting rod, pulling off the copper wire that is still connected between the rotor and the wire-breaking cylinder after winding, thus realizing automatic wire breaking after winding and eliminating the need for manual wire cutting.

[0021] In summary, this application includes the following beneficial technical effects: The winding assembly utilizes a winding motor, driven shaft, and winding claws working in concert to achieve automatic copper wire feeding and winding. A deflection assembly uses a deflection motor to precisely deflect the rotor, enabling batch automatic winding of copper wire in different winding slots. Guide protrusions on the guide block accurately guide the copper wire into the winding slots. A transverse positioning cylinder, a positioning wedge driven by a telescopic motor, and a positioning cylinder driven by a lifting cylinder work sequentially to reliably fix the rotor radially, circumferentially, and axially, respectively, ensuring stable winding. A wire-breaking assembly automatically clamps and breaks the copper wire after winding. The entire system automates the entire process from feeding, winding, indexing deflection, to wire breaking, significantly reducing manual intervention, lowering the workload for operators, and effectively improving production efficiency.

[0033] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0034] This application discloses a fully automatic motor winding device, referring to... Figures 1-2 The system includes a support box 1, a wire spool 114, a winding assembly 3, and a deflection assembly 4.

A rotor 7 is mounted on the deflection assembly 4. The winding assembly 3 winds the copper wire 8 onto the rotor 7, and the deflection assembly 4 deflects the rotor 7 at a certain angle, thus winding the copper wire 8 onto the rotor 7 in batches. The positioning mechanism 5 is mounted on the support box 1 and located on one side of the winding assembly 3. The positioning mechanism 5 positions the rotor 7 onto the deflection assembly 4.

[0035] Reference Figure 2The lead wire support frame 11 is fixedly connected to the top wall of the support box 1. A lead wire support plate 111 is fixedly connected to the end of the lead wire support frame 11 away from the pushing component 2. In this embodiment, four lead wire support plates 111 are provided and fixedly arranged along the length of the support box 1. Each lead wire support plate 111 is equipped with a lead wire rod 112. Specifically, the lead wire rod 112 is inclined, and its lower end is fixedly connected to the lead wire support plate 111. The other end of the lead wire rod 112 is fixedly connected to a first lead wire wheel 1121. Four vertical support rods 113 are fixedly arranged along the length of the support box 1 at the end of the lead wire support frame 11 near the pushing component 2. A second lead wire wheel 1131 is fixedly connected to the lower end of each vertical support rod 113, and each second lead wire wheel 1131 is located directly below a corresponding first lead wire wheel 1121.

[0036] Reference Figures 2-3 The pushing assembly 2 includes a pushing cylinder 21 and a pushing plate 22. The pushing cylinder 21 is fixedly connected to the top wall of the support box 1, and the pushing plate 22 is slidably connected to the top wall of the support box 1. The pushing plate 22 is located on one side of the lead wire support frame 11, and the end of the piston rod of the pushing cylinder 21 is connected to the pushing plate 22. The winding assembly 3 includes a winding motor 31 and a driven shaft 313, which is rotatably connected to the pushing plate 22. In this embodiment, four driven shafts 313 are provided and arranged along the length direction of the pushing plate 22. The axis of the driven shaft 313 is perpendicular to the length direction of the pushing plate 22 and is also perpendicular to the vertical line. Each driven shaft 313 is fixedly connected to a driven pulley 3132 near the end of the lead wire support frame 11, and every two adjacent driven pulleys 3132 are connected by a drive belt 312. A winding motor 31 is fixedly connected to the push plate 22 and located below the driven shaft 313. A drive pulley 311 is fixedly connected to the output shaft of the winding motor 31. The drive pulley 311 is connected to a driven pulley 3132 via a drive belt 312. Each driven shaft 313 is connected to a winding claw 314. In this embodiment, both the drive pulley 311 and the driven pulley 3132 are synchronous pulleys, and the drive belt 312 is a synchronous toothed belt.

[0037] Reference Figure 2 , Figure 4 and Figure 5In this embodiment, taking one of the driven shafts 313 as an example, each driven shaft 313 has a lead wire hole 3131 along its own axis. The inlet of the lead wire hole 3131 is located at one end near the lead wire support frame 11. An intermediate groove is located at the outlet of the lead wire hole 3131. An intermediate lead wire wheel 3133 is rotatably connected to the side wall of the intermediate groove. A winding lead wire wheel 3141 is rotatably connected to the winding claw 314, and the winding lead wire wheel 3141 is located on one side of the intermediate lead wire wheel 3133. A lead wire tube 3142 is fixedly connected to the end of the winding claw 314 away from the driven pulley 3132. The copper wire 8 on the coil 114 passes through the first lead wheel 1121 and the second lead wheel 1131, enters the lead hole 3131, passes through the lead hole 3131, and then passes through the intermediate lead wheel 3133 to wind onto the winding lead wheel 3141. Subsequently, it is led out from the lead tube 3142.

[0038] Reference Figures 6-8 The deflection assembly 4 includes a deflection motor 41, a telescopic motor 412, a sleeve 414, and a positioning wedge 415. The deflection motor 41 is vertically fixed inside the support box 1, and the top end of the output shaft of the deflection motor 41 extends from the top wall of the support box 1. A positioning hole 416 is vertically opened at the upper end of the output shaft of the deflection motor 41. A rotating shaft 71 is connected to the rotor 7, and a winding groove 72 is provided on the rotor 7. The rotor 7 is inserted into the positioning hole 416 opened in the output shaft of the deflection motor 41 through the rotating shaft 71.

[0039] Reference Figures 6-8 In this embodiment, three positioning structures for positioning the rotor 7 are provided, and the three positioning structures position the rotor 7 in a certain order. Specifically, the first positioning structure is as follows: a mounting plate 411 is coaxially connected to the output shaft of the deflection motor 41, and a telescopic motor 412 is vertically fixedly connected to the top wall of the mounting plate 411. Both the mounting plate 411 and the telescopic motor 412 are located inside the support box 1. A sleeve 414 is fitted onto the output shaft of the deflection motor 41, with its lower end located inside the support box 1 and extending from the top wall of the support box 1. The telescopic shaft of the telescopic motor 412 is fixedly connected to the sleeve 414 via a connecting block 413. A positioning wedge 415 is fixedly connected to the side wall of the sleeve 414. The telescopic motor 412 drives the positioning wedge 415 to insert into the winding groove 72 through the sleeve 414, thereby positioning the rotor 7 on the output shaft of the deflection motor 41.

[0040] Reference Figures 6-8The second positioning structure is as follows: the positioning mechanism 5 includes a positioning assembly composed of a mounting rod 52 and a transverse positioning cylinder 521. Four such positioning assemblies are provided, each located on one side of the output shaft of a deflection motor 41. The positioning assemblies are used to position the rotor 7. Specifically, the mounting rod 52 is vertically mounted on the top wall of the support box 1 and located on one side of the output shaft of the deflection motor 41. Simultaneously, the mounting rod 52 is also positioned opposite the winding claw 314. The transverse positioning cylinder 521 is fixedly connected to the upper end of the mounting rod 52. A positioning block 5211 is fixedly connected to the end of the piston rod of the transverse positioning cylinder 521, and the positioning block 5211 faces the rotor 7. The transverse positioning cylinder 521 pushes the positioning block 5211 against the side wall of the rotor 7 through the piston rod, thereby positioning the rotor 7 on the output shaft of the deflection motor 41.

[0041] Reference Figure 6 The third positioning structure is as follows: the positioning mechanism 5 further includes a lifting assembly 51, which includes a lifting cylinder 511, a lifting support frame 512, and a lifting plate 513. The lifting support frame 512 is vertically fixed to the top wall of the support box 1, and the lifting plate 513 is slidably connected to the lifting support frame 512. The lifting cylinder 511 is vertically fixed to the top wall of the support box 1, and the end of the piston rod of the lifting cylinder 511 is fixedly connected to the bottom wall of the lifting plate 513. Four positioning support rods 5131 are vertically connected to the bottom wall of the lifting plate 513. The four positioning support rods 5131 correspond one-to-one with the output shafts of the four deflection motors 41, and each positioning support rod 5131 is located directly above the output shaft of one deflection motor 41. Each positioning support rod 5131 has a positioning cylinder 5132 fixedly connected to its lower end. The lifting cylinder 511 drives the positioning support rod 5131 to move downward through the lifting plate 513, thereby positioning the rotor 7 on the output shaft of the deflection motor 41 through the positioning cylinder 5132.

[0042] Reference Figures 3-5 A guide block 315 is rotatably connected to one end of the driven shaft 313 near the output shaft of the deflection motor 41, and a counterweight is fixedly connected to the lower end of the guide block 315. A guide protrusion 3151 is fixedly connected to the guide block 315 near the output shaft of the deflection motor 41. (Refer to...) Figure 9When winding the small rotor, the winding claw 314 rotates with the driven shaft 313, but the guide block 315, due to the counterweight at its lower end, does not rotate with the driven shaft 313. The guide protrusion 3151 is used to guide the copper wire 8 into the winding slot 72 of the rotor 7. In this embodiment, two guide protrusions 3151 are provided and symmetrically fixedly connected to the guide block 315. The upper ends of the guide protrusions 3151 are both inclined downwards, and the two guide protrusions 3151 are used to guide the copper wire 8 into the two winding slots 72 spaced 150° apart. Specifically, when winding the rotor 7, the winding claw 314 first places the copper wire on the guide protrusion 3151, and then the copper wire slides along the upper surface of the guide protrusion 3151 into the two winding slots 72.

[0043] Reference Figures 6-8 The sequence of actions for the three positioning structures is as follows: The rotor 7 is inserted into the positioning hole 416 on the output shaft of the deflection motor 41. Then, the lateral positioning cylinder 521 pushes the positioning block 5211 against the side wall of the rotor 7 via its piston rod, thus initially positioning the rotor 7 on the output shaft of the deflection motor 41. Subsequently, the telescopic motor 412 drives the positioning wedge 415 through the sleeve 414 to be inserted into the winding groove 72, thereby positioning the rotor 7 on the output shaft of the deflection motor 41 to prevent the rotor 7 from freely deflecting on the output shaft of the deflection motor 41. When the winding claw 314 is about to wind the copper wire 8 onto the rotor 7, the lifting cylinder 511 drives the positioning support rod 5131 downwards via the lifting plate 513, thereby positioning the rotor 7 on the output shaft of the deflection motor 41 through the positioning cylinder 5132 to prevent the rotor 7 from moving upwards during the winding process.

[0044] Reference Figures 6-8When a portion of the copper wire 8 is wound into a pair of winding slots 72 spaced 150° apart, the lateral positioning cylinder 521 and the lifting assembly 51 disengage from the rotor 7. Subsequently, the deflection motor 41 drives the telescopic motor 412, the sleeve 414 and the positioning wedge 415 to deflect through the mounting plate 411, thereby driving the rotor 7 to deflect at a certain angle, so as to wind the copper wire 8 into the next pair of winding slots 72 spaced 150° apart. Subsequently, both the lateral positioning cylinder 521 and the lifting assembly 51 reposition the rotor 7. Simultaneously, the telescopic motor 412, through the sleeve 414, drives the positioning wedge 415 downwards, disengaging it from the rotor 7. The deflection motor 41 then drives the telescopic motor 412, sleeve 414, and positioning wedge 415 to rotate a certain angle, returning the positioning wedge 415 to its initial position. Then, the telescopic motor 412, through the sleeve 414, drives the positioning wedge 415 to insert into one of the winding slots 72, thereby positioning the rotor 7 on the output shaft of the deflection motor 41. The purpose of returning the positioning wedge 415 to its initial position is that if the positioning wedge 415 remains in one of the winding slots 72 of the rotor 7, it will interfere with the winding claw 314 winding a pair of winding slots 72.

[0045] Reference Figure 6 and Figure 10 The lifting assembly 51 is also connected to a wire breaking assembly 6. Specifically, the wire breaking assembly 6 includes a moving cylinder 61, which is fixedly connected to the top wall of the lifting plate 513, and the length direction of the moving cylinder 61 is parallel to the length direction of the lifting plate 513. Vertical connecting rods 611, the same number as the winding claws 314, are fixedly connected along the length direction of the moving cylinder 61. A wire breaking cylinder 612 is fixedly connected to the lower end of each vertical connecting rod 611. Each wire breaking cylinder 612 is located on one side of the winding claw 314, and a clamping block 6121 is fixedly connected to the end of the piston rod of each wire breaking cylinder 612. The wire breaking cylinder 612 is used for hanging and breaking the wire.

[0046] Reference Figures 4-6 Before winding the rotor 7 using the winding claw 314, the copper wire drawn from the lead tube 3142 needs to be clamped by the wire-cutting cylinder 612, thus attaching the copper wire 8 to the wire-cutting cylinder 612. Subsequently, the winding claw 314 rotates and continuously pulls out the copper wire 8 from the lead tube 3142, winding it into the winding slot 72 of the rotor 7. After the winding claw 314 rotates a certain number of times, the copper wire 8 is wound around the rotor 7. The moving cylinder 61 drives the wire-cutting cylinder 612 to move along the length of the lifting plate 513 via the vertical connecting rod 611, thereby breaking the copper wire 8 between the rotor 7 and the wire-cutting cylinder 612. The purpose of breaking the copper wire 8 between the rotor 7 and the wire-cutting cylinder 612 is that after the rotor 7 completes the winding work, it can be directly removed from the output shaft of the deflection motor 41, thus reducing the labor intensity of workers cutting the copper wire 8.

[0047] The implementation principle of the fully automatic motor winding device in this application embodiment is as follows: the copper wire 8 on the coil 114 is guided by the lead wire support frame 11, passes through the first lead wire wheel 1121 and the second lead wire wheel 1131 in sequence, and is then led to the winding claw 314. After the winding motor 31 is started, the drive pulley 311 on the output shaft of the winding motor 31 drives all the driven pulleys 3132 to rotate synchronously through the drive belt 312, thereby driving all the driven shafts 313 and the winding claws 314 fixed at their ends to rotate together.

[0048] Before the winding operation begins, the push cylinder 21 of the push assembly 2 drives the push plate 22 to move closer to the rotor 7, causing the entire winding assembly 3 mounted on the push plate 22 to advance until the winding claw 314 reaches the preset winding start position. This pushing action ensures the initial working distance of the winding operation. The wire breaking cylinder 612 of the wire breaking assembly 6 is activated first, clamping the copper wire 8 drawn from the winding lead wheel 3141 by the clamping block 6121, completing the wire hanging and providing a fixed starting fulcrum for winding. Subsequently, the winding claw 314 begins to rotate, winding the copper wire 8 into a pair of winding slots 72 spaced 150° apart on the rotor 7. When the copper wire 8 has been wound to the predetermined number of turns and it is ensured that the copper wire 8 is fixed on the rotor 7 and will not come off, the moving cylinder 61 drives the vertical connecting rod 611 to move, and the copper wire 8 is broken by the wire breaking cylinder 612 and the clamping block 6121.

[0049] To achieve batch winding of copper wire 8, after winding a pair of winding slots 72, the deflection motor 41 of the deflection assembly 4 starts according to a preset program. The output shaft of the deflection motor 41 drives the rotor 7 to deflect to the working angle required for the next pair of winding slots 72. During this deflection and subsequent winding process, three positioning structures operate sequentially to ensure the stability of the rotor 7: the lateral positioning cylinder 521 of the second positioning structure pushes the positioning block 5211 to achieve initial positioning; the telescopic motor 412 of the first positioning structure drives the positioning wedge 415 to insert into the corresponding slot of the motor to prevent circumferential deflection; the lifting cylinder 511 of the third positioning structure drives the positioning cylinder 5132 to press the top of the rotor 7 to prevent axial movement. This multi-sequence positioning method ensures the absolute stability of the motor during winding. The guide protrusion 3151 on the winding claw 314 ensures that the copper wire 8 can be accurately guided into the winding slot 72.

[0050] This application achieves continuous operation of winding, deflection, positioning and wire breaking processes through fully automated design, reducing manual intervention, lowering the workload of operators and improving production efficiency.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
