Description

Technical Field

[0001] This invention relates to the field of coil winding equipment technology, specifically a winding machine for stator and rotor coils of an excitation motor. Background Technology

[0002] As a core power device in the industrial drive field, the electromagnetic performance, energy efficiency, and operational reliability of the excitation motor are directly determined by the winding quality of its stator and rotor coils. The stator and rotor coils, as the key carriers for generating the motor's magnetic field, must meet stringent requirements for geometric accuracy, turn consistency, and insulation integrity.

[0003] Existing coil winding equipment, such as the fully automatic coil winding method for a motor rotor proposed in patent application number "CN110739818B", involves the following steps: First, the user pulls out the free end of the copper wire wound on the wire storage mechanism and passes it sequentially through the lead wire mechanism and the wire feeding wheel, and then fixes it to the winding surface at the working position; then, the winding device drives the entire motor rotor to rotate axially along the length direction parallel to the chassis, and the winding surface at the working position rotates, causing the copper wire to be gradually released and wound onto the winding surface; next, the winding device drives the entire motor rotor to rotate gradually around the rotor shaft, so that the winding surface in the idle position is switched to the working position for winding; finally, after the winding is completed, the copper wire is cut, the lifting and deflection mechanism drives the rotation adjustment mechanism and the clamping and changing mechanism to move downward and rotate away from the wire feeding device, and the motor rotor is unloaded by the hoisting equipment.

[0004] However, in practical applications, the aforementioned patented technology still reveals some significant shortcomings. It uses a winding device to drive the motor rotor to rotate axially along the length direction parallel to the chassis, and uses a wire guide wheel to wind the copper wire against the rotor winding surface. This method cannot embed the copper wire into the winding end inside the annular stator, affecting the applicability of the device. Summary of the Invention

[0018] The beneficial effects of this invention are:

[0019] 1. This invention uses a three-jaw chuck to clamp and fix the rotor body, and a transfer mechanism drives it to move along the transfer groove to the side of the L-shaped hollow lead rod. At this time, the winding assembly pulls the coil to circulate and wind the winding surface at the end of the rotor winding. During the winding process, the transfer mechanism simultaneously fine-tunes the distance between the rotor body and the L-shaped hollow lead rod. Combined with the indexing rotation of the self-rotation mechanism, the copper wire is evenly wound on the winding surface at the end of the rotor winding. Similarly, after the stator body is fixed by a two-jaw chuck, the transfer mechanism positions it in the working area of ​​the L-shaped hollow lead rod. At this time, the winding mechanism drives the L-shaped hollow lead rod to insert into the stator body at the position corresponding to the end of the stator winding, thereby achieving tight winding of the copper wire on the inner side of the stator winding end. This realizes automatic circulatory winding of the winding surfaces at the ends of the rotor and stator windings, effectively improving the applicability of the device.

[0020] 2. By setting up a transmission rod in conjunction with a follower slide groove and a guide slide rod, this invention facilitates the rotation of the transmission rod when the wound motor is started. The guide slide rod then drives the L-shaped hollow lead rod along the guide track of the follower slide groove, circulating along the winding surfaces of the rotor winding end and the stator winding end. This facilitates the driving of the L-shaped hollow lead rod to pull the coil winding along the winding surfaces of the rotor winding end and the stator winding end, effectively improving the practicality of the device.

[0021] 3. In this invention, when the coil is wound by pulling the coil with the L-shaped hollow lead rod, the coil pulls the adjusting roller one along the length of the adjusting groove by using the adjusting roller two as the fulcrum to compress the adjusting spring and generate a contraction deformation. When the electric unwinding shaft causes the coil to loosen due to uneven unwinding, the elastic potential energy of the adjusting spring is used to push the adjusting roller one along the length of the adjusting groove to push the coil out, so as to achieve automatic adjustment of the tension of the coil.

[0022] 4. This invention, through the coordinated use of an arc-shaped rack and an adjusting gear, enables the starting adjustment component to drive the arc-shaped rack to mesh with the adjusting gear, and to drive the mounting plate to deflect around the hinge axis. This causes the mounting plate to drive the traction end of the L-shaped hollow lead rod to shorten the distance between it and the winding surface of the rotor winding end or stator winding end, ensuring that the coil is precisely fitted to the winding surface of the rotor winding end and the stator winding end for winding. At the same time, the adaptive tilt angle adjustment reduces the friction between the coil and the edges of the rotor winding end and the stator winding end. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] A winding machine for stator and rotor coils of an excitation motor, wherein a winding mechanism cooperates with a transfer mechanism and a rotation mechanism, and the traction coil 11 is cyclically wound along the winding surface of the rotor winding end 8 or the stator winding end 9, such as... Figure 1 and Figure 2 As shown, the three-jaw chuck 4 and the two-jaw chuck 5 respectively transfer the rotor body 6 and the stator body 7 to one end of the L-shaped hollow lead rod 12, and respectively pull the coil winding 11 to wind the winding surfaces of the rotor winding end 8 and the stator winding end 9, which belongs to a type of coil winding device.

[0036] like Figures 1-6 As shown, the device includes a base 1, and a pair of transfer grooves 2 are provided on the top of the base 1. Transfer slider 1 and transfer slider 2 are slidably connected inside the two transfer grooves 2 respectively. A three-jaw chuck 4 is rotatably connected to the top of transfer slider 1. The three-jaw chuck 4 is a BISON 3-Jaw Self-Centering Chuck model. A two-jaw chuck 5 is fixedly connected to the top of transfer slider 2. The two-jaw chuck 5 is an OnRobot RG2 / RG6 jaw. The clamping end of the three-jaw chuck 4 clamps the rotor body 6, and the clamping end of the two-jaw chuck 5 clamps the stator body 7.

[0037] One end of the base 1 is equipped with a winding mechanism, which is used to wind copper wires onto the rotor body 6 and the stator body 7. One end of the base 1 is equipped with a transfer mechanism, which is used to drive the three-jaw chuck 4 and the two-jaw chuck 5 to move directionally along the length direction of transfer slider 1 and transfer slider 2, so as to change the relative position of the three-jaw chuck 4 and the two-jaw chuck 5. One end of transfer slider 1 and transfer slider 2 is equipped with a rotation mechanism, which is used to drive the rotor body 6 and the stator body 7 to rotate.

[0038] The winding mechanism includes multiple rotor winding ends 8 evenly arranged around the rotor body 6, multiple stator winding ends 9 evenly arranged inside the stator body 7, and an electric unwinding shaft 10 rotatably connected to one end of the base 1. The electric unwinding shaft 10 is an INOVANCE IS620N-1T0. A coil coil 11 is fixedly sleeved on one end of the electric unwinding shaft 10. An L-shaped hollow lead rod 12 is arranged above the base 1. One end of the coil coil 11 passes through the L-shaped hollow lead rod 12 and extends to one side of the rotor winding end 8 or the stator winding end 9. A winding assembly for driving the L-shaped hollow lead rod 12 to move around the winding surface along the rotor winding end 8 or the stator winding end 9 is installed at one end of the base 1.

[0039] In use, the rotor body 6 is first clamped and fixed by activating the three-jaw chuck 4, and the transfer mechanism is activated to drive the three-jaw chuck 4 to move the rotor body 6 along the length of the transfer groove 2 to one side of the L-shaped hollow lead rod 12. At this time, the two-jaw chuck 5 is pushed by the transfer mechanism and moves away from the L-shaped hollow lead rod 12 along the length of the transfer groove 2 to reduce the interference of the two-jaw chuck 5 on the operation of the L-shaped hollow lead rod 12. Then, one end of the traction coil 11 passes through the interior of the L-shaped hollow lead rod 12 and is fixedly connected to one end of the rotor winding end 8. Next, the winding assembly is started to drive the L-shaped hollow lead rod 12 to drive one end of the coil 11 to fit against the winding surface of the rotor winding end 8 for cyclic winding. At the same time, the transfer mechanism drives the three-jaw chuck 4 to drive the rotor body 6 to move along the length direction of the transfer groove 2, and drives the rotor winding end 8 to move in a small range towards or away from the L-shaped hollow lead rod 12 along the length direction of the transfer groove 2, so that the L-shaped hollow lead rod 12 drives the coil 11 to be wound evenly on the winding surface of the rotor winding end 8. After completing the winding of one rotor winding end 8, the rotation mechanism is started to drive the three-jaw chuck 4 to drive the rotor body 6 to rotate, so that the next rotor winding end 8 rotates to one side of the L-shaped hollow lead rod 12 and the copper wire is wound in the same way. This facilitates the winding of copper wire on the rotor winding end 8 around the rotor body 6.

[0040] Then, when it is necessary to wind copper wire at the stator winding end 9 inside the stator body 7, the two-jaw chuck 5 is activated to clamp and fix the stator body 7, and the transfer mechanism is activated to drive the two-jaw chuck 5 to move the stator body 7 along the length direction of the transfer slide 2 to one end of the L-shaped hollow lead rod 12, and drive the three-jaw chuck 4 to move away from the L-shaped hollow lead rod 12 along the length direction of the transfer slide 2. At this time, the winding assembly is activated to drive the L-shaped hollow lead rod 12 to insert into the interior of the stator body 7, and drive the coil coil 11 to fit against the winding surface of the stator winding end 9. Then, the winding mechanism is activated again to drive the L-shaped hollow lead rod 12 to drive the coil coil 11 along the stator winding... The winding surface of end 9 is cyclically wound, and the transfer mechanism drives the two-jaw chuck 5 to move the stator body 7 along the length direction of the transfer groove 2. This causes the stator body 7 to move the stator winding end 9 along the length direction of the transfer groove 2 in a small range toward or away from the L-shaped hollow lead rod 12, so that the copper wire is evenly wound on the winding surface of the stator winding end 9. In this way, the winding assembly can drive the L-shaped hollow lead rod 12 to move cyclically against the winding surfaces of the rotor winding end 8 and the stator winding end 9, thereby realizing the winding of the copper wire against the winding surfaces of the rotor winding end 8 and the stator winding end 9, which effectively improves the applicability of the device.

[0041] like Figures 1-6 As shown, the winding assembly includes a mounting plate 13 hinged to one end of the base 1. A rectangular guide groove 14 is provided on one side of the mounting plate 13. A guide slide rod 15 is slidably connected inside the rectangular guide groove 14. A transmission rod 16 is rotatably connected to one end of the mounting plate 13. The hinged end of the transmission rod 16 is located at the center of the rectangular guide groove 14. A follower slide groove 17 is provided at one end of the transmission rod 16. One end of the guide slide rod 15 passes through the follower slide groove 17 and is fixedly connected to the L-shaped hollow lead rod 12. A winding motor 18 is fixedly connected to one side of the mounting plate 13. The output end of the winding motor 18 is fixedly connected to the hinged end of the transmission rod 16. A guide assembly for guiding the L-shaped hollow lead rod 12 to move along the guide direction of the rectangular guide groove 14 is installed at one end of the mounting plate 13.

[0042] The guide assembly includes a guide slide rod 19 fixedly connected to the top of the guide slide rod 15. A rectangular guide groove 20 is provided on one side of the mounting plate 13. One end of the guide slide rod 19 is embedded in the rectangular guide groove 20 and is slidably connected to the rectangular guide groove 20.

[0043] Furthermore, one end of the guide slide rod 15 is fixedly connected to a tension adjusting frame 21, one end of the tension adjusting frame 21 is provided with an adjusting groove 22, an adjusting slider 23 is slidably connected inside the adjusting groove 22, one end of the adjusting slider 23 is rotatably connected to an adjusting roller 24, one end of the adjusting groove 22 is rotatably connected to an adjusting roller 25, the bottom of the guide slide rod 15 is fixedly connected to an adjusting slide rod 26, one end of the adjusting slider 23 is slidably sleeved on the outside of the adjusting slide rod 26, one end of the adjusting slide rod 26 is sleeved with an adjusting spring 27, and the adjusting spring 27 is installed between the adjusting slider 23 and the guide slide rod 15.

[0044] In use, one end of the traction coil 11 first passes around the top of the adjusting roller 25 and the bottom of the adjusting roller 24, then passes through the L-shaped hollow lead rod 12 and forms a fixed connection with the winding surface of the rotor winding end 8 or the stator winding end 9. At the same time, one end of the coil 11 pulls the adjusting roller 24, causing the adjusting slider 23 to move upward along the length of the adjusting groove 22, and causing the adjusting slider 23 to compress the adjusting spring 27 and generate a contraction deformation. At this time, the adjusting spring 27 accumulates elastic potential energy, and then the winding motor 18 is started. The drive rod 16 rotates, causing it to push one end of the guide slide rod 15 to abut against the inner wall of the follower slide groove 17. At the same time, it moves along the guiding direction of the rectangular guide groove 14, causing the guide slide rod 15 to drive the guide slide rod 19 to slide along the inside of the rectangular guide groove 20. This causes the guide slide rod 15 to drive the L-shaped hollow lead rod 12 to pull one end of the coil winding 11 to move cyclically along the winding surface of the rotor winding end 8 or the stator winding end 9, so as to realize the cyclic winding of the coil winding 11.

[0045] When the unwinding speed of the electric unwinding shaft 10 deviates from the winding speed of the coil 11 pulled by the L-shaped hollow lead rod 12, the middle section of the coil 11 becomes loose, thereby reducing the tension applied to the adjusting roller 24. This causes the adjusting spring 27 to release its elastic potential energy and push out the adjusting slider 23 along the length direction of the adjusting slide rod 26. As a result, the adjusting slider 23 pushes the middle section of the coil 11 downward along the length direction of the adjusting slide groove 22 to tighten the middle section of the coil 11, thus facilitating the automatic adjustment of the tension of the coil 11.

[0046] like Figures 1-3 , Figure 6 As shown, an arc-shaped rack 28 is fixedly connected to one end of the mounting plate 13, and an adjusting gear 29 that meshes with the arc-shaped rack 28 is rotatably connected to one end of the base 1. An adjusting component for driving the adjusting gear 29 to rotate is installed at one end of the base 1.

[0047] The adjustment assembly includes a driven wheel 30 rotatably connected to one end of the base 1, a driving wheel 31 rotatably connected to the other end of the base 1, a synchronous belt 32 sleeved around the driven wheel 30 and the driving wheel 31, an adjustment motor 33 fixedly connected to one end of the base 1, the output end of the adjustment motor 33 fixedly connected to the driving wheel 31, and the diameter ratio of the driven wheel 30 to the driving wheel 31 is 2:1.

[0048] In use, when the winding mechanism is activated, driving the L-shaped hollow lead rod 12 to drive the coil winding 11 to circulate along the winding surface of the rotor winding end 8 or the stator winding end 9, the starting adjustment motor 33 can drive the driving wheel 31 to rotate. The driving wheel 31 then drives the driven wheel 30 to rotate via the synchronous belt 32. Simultaneously, utilizing the diameter difference between the driven wheel 30 and the driving wheel 31, the driven wheel 30 drives the adjusting gear 29 to rotate slowly. This causes the adjusting gear 29 to mesh with the arc-shaped rack 28, which in turn causes the arc-shaped rack 28 to drive the mounting plate 13 to rotate around the hinge axis. The mounting plate 13 deflects the L-shaped hollow lead rod 12 around the hinge axis, causing the L-shaped hollow lead rod 12 to pull the coil coil 11 into the inner side of the rotor winding end 8 or the stator winding end 9. This effectively shortens the distance between the traction end of the L-shaped hollow lead rod 12 and the winding surface of the rotor winding end 8 and the stator winding end 9, ensuring that the coil coil 11 accurately fits the winding surface of the rotor winding end 8 and the stator winding end 9 for winding. At the same time, the adaptive tilt angle adjustment reduces the friction between the coil coil 11 and the edges of the rotor winding end 8 and the stator winding end 9, improving the practicality of the device.

[0049] like Figure 1 and Figure 2 , Figure 7 and Figure 8 As shown, the transfer mechanism includes transfer racks 34 fixedly connected to one side of transfer slider one and transfer slider two respectively. A transfer gear 35 is rotatably connected to one end of the base 1. The two transfer racks 34 are arranged opposite each other and mesh synchronously with the transfer gear 35. A worm gear 36 is fixedly connected to one end of the transfer gear 35. A worm 37 that meshes with the worm gear 36 is rotatably connected to one end of the base 1. A transfer motor 38 is fixedly connected to one end of the base 1. The output end of the transfer motor 38 is fixedly connected to the worm 37.

[0050] In use, the worm 37 is first driven to rotate by starting the transfer motor 38, which in turn drives the worm 37 to mesh with the worm wheel 36. This causes the worm wheel 36 to drive the transfer gear 35 to rotate synchronously, so that the transfer gear 35 meshes synchronously with the two transfer racks 34. The two transfer racks 34 drive the two transfer sliders 1 and 2 to move away from or towards each other along the length of the transfer groove 2. At the same time, the transfer sliders 1 and 2 drive the three-jaw chuck 4 and the two-jaw chuck 5 to move closer to or away from the L-shaped hollow lead rod 12 along the length of the transfer groove 2, respectively. This facilitates the driving of the three-jaw chuck 4 and the two-jaw chuck 5 to drive the rotor body 6 and the stator body 7 to move along the length of the transfer groove 2, effectively improving the practicality of the device.

[0051] like Figure 1 and Figure 2 , Figures 7-9 As shown, the self-rotation mechanism includes a rubber abutment wheel 39 rotatably connected to one end of the transfer slider 2. One end of the rubber abutment wheel 39 passes through the transfer slider 2 and is fixedly connected to a driven wheel 40. One end of the transfer slider 2 is rotatably connected to a driving wheel 41. A synchronous belt 42 is sleeved around the driven wheel 40 and the driving wheel 41. One end of the transfer slider 2 is fixedly connected to a rotary motor 43. The output end of the rotary motor 43 is fixedly connected to the driving wheel 41. A pair of clamping wheels 44 are symmetrically hinged to the clamping end of the two-jaw chuck 5. The stator body 7 is installed between the rubber abutment wheel 39 and the clamping wheels 44. One end of the transfer slider 1 is equipped with a self-rotation component for driving the three-jaw chuck 4 to rotate.

[0052] The self-rotating component includes a transmission gear 45 fixedly connected to one end of the three-jaw chuck 4, a transmission gear 46 rotatably connected to one end of the transfer slider 4, and a rotary motor 47 fixedly connected to one end of the transfer slider 4. The output end of the rotary motor 47 is fixedly connected to the transmission gear 46.

[0053] In use, after the winding mechanism is started and the copper wire of the end 9 of one stator winding inside the stator body 7 is wound, the drive wheel 41 is driven by the start of the rotary motor 43 to drive the driven wheel 40 to rotate synchronously through the synchronous belt 42. At the same time, the driven wheel 40 drives the rubber contact wheel 39 to rotate. At this time, the rubber contact wheel 39 rolls against the stator body 7, which is driven by the two jaw chuck 5 to roll and hold the two pairs of clamping wheels 44. This pushes the stator body 7 to rotate the end 9 of the stator winding, so that the stator body 7 drives the next end 9 of the stator winding to rotate concentrically to one side of the L-shaped hollow lead rod 12, so as to realize the replacement of the end 9 of the stator winding that needs to be wound.

[0054] Similarly, after the winding mechanism completes the winding of copper wire on the winding surface of one rotor winding end 8 around the rotor body 6, the second rotary motor 47 can drive the second transmission gear 46 to mesh with the first transmission gear 45, and the first transmission gear 45 drives the three-jaw chuck 4 to rotate, and the three-jaw chuck 4 drives the rotor body 6, which is clamped and fixed, to rotate. This causes the rotor body 6 to drive multiple rotor winding ends 8 to rotate, so as to drive the next rotor winding end 8 that needs to be wound to rotate to one side of the L-shaped hollow lead rod 12, thereby facilitating the replacement of the rotor winding end 8 that needs to be wound.

[0055] The working principle of the excitation motor stator and rotor coil winding machine provided by this invention is as follows:

[0056] First, the rotor body 6 is clamped and fixed by activating the three-jaw chuck 4, and the worm 37 is driven to mesh with the worm wheel 36 by activating the transfer motor 38. This causes the worm wheel 36 to drive the transfer gear 35 to rotate synchronously, so that the transfer gear 35 meshes synchronously with the two transfer racks 34. The two transfer racks 34 drive the transfer slider one and the transfer slider two to move away from or towards each other along the length of the transfer groove 2. At the same time, the transfer slider one drives the three-jaw chuck 4 to move the rotor body 6 along the length of the transfer groove 2 to one side of the L-shaped hollow lead rod 12. At this time, the transfer slider two drives the three-jaw chuck 4 to move the two-jaw chuck 5 along the length of the transfer groove 2 to the side away from the L-shaped hollow lead rod 12. The movement direction of the two-jaw chuck 5 and the rotor body 6 can be reversed by reversing the activation of the transfer motor 38.

[0057] Then, one end of the traction coil 11 passes around the top of the second adjusting roller 25 and the bottom of the first adjusting roller 24 in sequence, and then passes through the L-shaped hollow lead rod 12 to form a fixed connection with the winding surface of the rotor winding end 8 or the stator winding end 9. At the same time, one end of the coil 11 pulls the first adjusting roller 24 to drive the adjusting slider 23 to move upward along the length direction of the adjusting groove 22, and causes the adjusting slider 23 to compress the adjusting spring 27 to produce a contraction deformation. At this time, the adjusting spring 27 accumulates elastic potential energy.

[0058] Then, the winding motor 18 is started to drive the transmission rod 16 to rotate, and the transmission rod 16 pushes one end of the guide slide rod 15 to abut against the inner wall of the follower slide groove 17. At the same time, it moves along the guiding direction of the rectangular guide groove 14, and the guide slide rod 15 drives the guide slide rod 19 to slide along the inside of the rectangular guide groove 20. Thus, the guide slide rod 15 drives the L-shaped hollow lead rod 12 to pull one end of the coil winding 11 to move cyclically along the winding surface of the rotor winding end 8 or the stator winding end 9, so as to realize the cyclic winding of the coil winding 11.

[0059] When the unwinding speed of the electric unwinding shaft 10 to the coil 11 deviates from the winding speed of the coil 11 pulled by the L-shaped hollow lead rod 12, the middle section of the coil 11 becomes loose, thereby reducing the tension applied to the adjusting roller 24. This causes the adjusting spring 27 to release its elastic potential energy and push out the adjusting slider 23 along the length direction of the adjusting slide rod 26. As a result, the adjusting slider 23 pushes the middle section of the coil 11 downward along the length direction of the adjusting slide groove 22 to tighten the middle section of the coil 11.

[0060] Next, the transfer mechanism drives the three-jaw chuck 4 to move the rotor body 6 or the two-jaw chuck 5 to move the stator body 7 along the length direction of the transfer groove 2, and drives the rotor winding end 8 or the stator winding end 9 to move in a small range towards or away from the L-shaped hollow lead rod 12 along the length direction of the transfer groove 2, so that the L-shaped hollow lead rod 12 drives the coil winding 11 to be evenly wound on the winding surface of the rotor winding end 8 or the stator winding end 9. After completing the winding of one rotor winding end 8 or stator winding end 9 winding surface;

[0061] By starting the rotary motor 47, the transmission gear 46 is driven to mesh with the transmission gear 45, which in turn drives the three-jaw chuck 4 to rotate. The three-jaw chuck 4 then drives the rotor body 6, which is clamped and fixed, to rotate. This causes the rotor body 6 to drive multiple rotor winding ends 8 to rotate, so that the next rotor winding end 8 to be wound can rotate to one side of the L-shaped hollow lead rod 12. Similarly, starting the rotary motor 43 drives the driving wheel 41 to rotate synchronously via the synchronous belt 42. At the same time, the driven wheel 40 drives the rubber contact wheel 39 to rotate. This causes the rubber contact wheel 39 to roll against the stator body 7, which is rolled and clamped by the two pairs of clamping wheels 44 driven by the two-jaw chuck 5. This pushes the stator body 7 to rotate, causing the stator winding end 9 to rotate. This causes the stator body 7 to drive the next stator winding end 9 to rotate concentrically to one side of the L-shaped hollow lead rod 12.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
