Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically a winding device for motor manufacturing. Background Technology

[0002] An electric motor generally consists of two parts: a rotor and a stator. The rotor is the rotating part of the motor. The rotor generally includes rotor teeth and windings wound on the rotor teeth. Existing motor rotors require a winding device when winding the coils.

[0003] Chinese patent CN 118353219 B discloses a rapid winding device for motor manufacturing, including a base plate and a vertical plate. The vertical plate is fixedly connected to the top of the base plate. A clamping assembly is provided on the top of the base plate. An installation assembly and a moving assembly are provided on the outer wall of the vertical plate. The clamping assembly consists of a rotating unit and a moving unit, with the rotating unit located on the outer wall of the vertical plate and the moving unit located on the top of the base plate. The moving assembly consists of an adjusting unit and a power unit, with the adjusting unit and the power unit located on the outer wall of the vertical plate. This rapid winding device for motor manufacturing, by setting a second connector, a connecting column, and ball bearings, allows for maintenance of the connecting column by sliding the second connector, which applies pressure to the ball bearings, which in turn applies pressure to a lifting plate until the second connector separates from the connecting column, at which point maintenance operations can be performed on the connecting column.

[0004] Existing winding devices cannot easily adjust the tension of the wires during the winding process of motor rotors, which can easily lead to inconsistent outer diameters of the coils and poor wire uniformity. Therefore, a winding device for motor manufacturing is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a winding device for motor manufacturing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a winding device for motor manufacturing, including a base, a control panel mounted on the base, a first guide plate mounted on the base, a first guide groove formed in the first guide plate, a first guide block assembled in the first guide groove, a second guide plate mounted on the first guide block, a second guide groove formed on the second guide plate, a second stepper motor mounted on the second guide plate via a base, a second lead screw mounted on the output shaft of the second stepper motor, the second lead screw rotatably mounted on the inner wall of the second guide groove, a second guide block assembled in the second guide groove, a lifting block mounted on the second guide block, an indicator light mounted on the lifting block, a sliding groove formed in the lifting block, a slider assembled in the sliding groove, a first electrode plate mounted on the bottom side of the slider, and the sliding groove... A second electrode plate is installed on the inner wall, and a guide wheel is rotatably mounted on the slider. A connecting frame is installed on the second guide plate, and a guide tube is installed on the connecting frame. The first and second electrode plates are connected to an indicator light through an internal circuit. The indicator light is connected to a control panel through an internal circuit, and the control panel is connected to a second stepper motor through an internal circuit. When the wire becomes slack, the guide wheel moves vertically downward under its own weight, activating the tension adjustment component. As the guide wheel moves vertically downward, it presses the wire downward under its own weight until the wire is taut. The tension adjustment component then deactivates. When the wire becomes slack again, the above steps are repeated. This structure can automatically and conveniently adjust the wire tension, avoiding inconsistencies in the outer diameter of the coil and improving the neatness of the wire.

[0007] A first stepper motor is mounted on the first guide plate via a base. A first lead screw is mounted on the output shaft of the first stepper motor. The first lead screw is rotatably mounted on the inner wall of the first guide groove. A third guide plate is mounted on the base. A third guide groove is formed in the third guide plate. A third lead screw is rotatably mounted on the inner wall of the third guide groove. The threads on the third lead screw are symmetrically opposite in direction. A knob is mounted on one end of the third lead screw. A damping wheel is mounted around the knob. Two sets of third guide blocks are symmetrically assembled in the third guide groove. A movable plate is mounted on the third guide block. A clamping block is rotatably mounted on the movable plate. A motor rotor is placed between the two sets of clamping blocks. A third lead screw is mounted on one of the movable plates via a base. A three-stepper motor has its output shaft fixedly connected to the rotating shaft of the clamping block. A fixing plate is installed on the bottom side of the base, and a support frame is installed on the fixing plate. A release wheel is rotatably mounted on the support frame. A second drive motor is mounted on the support frame via a base. The output shaft of the second drive motor is fixedly connected to the rotating shaft of the release wheel. A wire is wound on the release wheel. The wire is pulled horizontally and reciprocally through a wire tube, while the motor rotor rotates reciprocally by 5°, so that the wire is evenly wound on the motor rotor. After one rotor tooth is wound, the clamping block will drive the motor rotor to rotate 45°, and then repeat the above steps. This structure can continuously and efficiently wind the motor rotor, which is beneficial to improving the winding efficiency.

[0008] The advantages of this utility model are:

[0009] 1. This utility model utilizes a tension adjustment component. When the conductor becomes slack, the conductor wheel moves vertically downward under its own weight. Simultaneously, the tension adjustment component presses the conductor downward under its own weight until the conductor is taut. The tension adjustment component then closes. When the conductor becomes slack again, the above steps are repeated. This structure can automatically and conveniently adjust the conductor tension, avoiding inconsistencies in the outer diameter of the coil and improving the neatness of the conductor.

[0010] 2. This utility model uses a wire guide tube to move the wire horizontally back and forth, while the motor rotor rotates back and forth by 5°, so that the wire is evenly wound on the motor rotor. After one rotor tooth is wound, the clamp will drive the motor rotor to rotate 45°, and then repeat the above steps. This structure can continuously and efficiently wind the motor rotor, which is beneficial to improving the winding efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1-4As shown, a winding device for motor manufacturing includes a base 1, a control panel 2 mounted on the base 1, a first guide plate 3 mounted on the base 1, a first guide groove 4 formed in the first guide plate 3, a first guide block 7 assembled in the first guide groove 4, a second guide plate 8 mounted on the first guide block 7, a second guide groove 9 formed on the second guide plate 8, a second stepper motor 10 mounted on the second guide plate 8 via a base, and a second lead screw 11 mounted on the output shaft of the second stepper motor 10, the second lead screw 11 being rotatably mounted on the inner wall of the second guide groove 9. The second guide groove 9 is equipped with a second guide block 12, a lifting block 13 is mounted on the second guide block 12, an indicator light 14 is mounted on the lifting block 13, a sliding groove 15 is opened in the lifting block 13, a slider 16 is assembled in the sliding groove 15, a first electrode plate 17 is mounted on the bottom side of the slider 16, a second electrode plate 18 is mounted on the inner wall of the sliding groove 15, a guide wheel 19 is rotatably mounted on the slider 16, a connecting frame 34 is mounted on the second guide plate 8, and a guide tube 35 is mounted on the connecting frame 34. The first electrode plate 17 and the second electrode plate 18 are connected by an internal circuit. The indicator light 14 is connected to the control panel 2 via an internal circuit. The control panel 2 is connected to the second stepper motor 10 via an internal circuit. During operation, the existing winding device cannot easily adjust the tension of the wire 33 during the winding process of the motor rotor 27, which easily causes the outer diameter of the coil to be inconsistent, resulting in poor neatness of the wire 33. During the winding process of the motor rotor 27, since the wire wheel 19 is located between the release wheel 31 and the motor rotor 27 and is located in the concave part, the wire wheel 19 is always in contact with the wire 33. When the wire 33 becomes slack, the wire wheel 19 will move vertically downward under its own weight. The wire wheel 19 drives the slider 16 on it to move vertically downward. The slider 16 drives the first electrode plate 17 on it to move vertically downward, so that the first electrode plate 17 contacts the second electrode plate 18. At this time, the internal circuit of the indicator light 14 is turned on, and the indicator light 14 sends an electrical signal to the control panel 2. After receiving the electrical signal, the control panel 2 controls the second stepper motor 10 to operate, realizing the opening of the tension adjustment component.

[0020] The second stepper motor 10 drives the second lead screw 11 to rotate, which in turn drives the second guide block 12 to move vertically downward. The second guide block 12 drives the lifting block 13 to move vertically downward, which in turn drives the slider 16 to move vertically downward. The slider 16 drives the guide wheel 19 to move vertically downward. As the guide wheel 19 moves vertically downward, it presses the guide wire 33 downward under its own weight until the guide wire 33 is in a taut state. When the guide wire 33 is in a taut state, it will obstruct the guide wheel 19. The slider 16 will stop moving downwards, but the lifting block 13 will continue to move downwards, causing the first electrode plate 17 and the second electrode plate 18 to separate quickly. The electrical signal of the indicator light 14 will disappear. At this time, the control panel 2 controls the second stepper motor 10 to stop operating, causing the lifting block 13 to stop moving downwards, thus closing the tension adjustment component. When the wire 33 becomes slack again, the above steps are repeated. This structure can automatically and conveniently adjust the tension of the wire 33, avoiding inconsistencies in the outer diameter of the coil and improving the neatness of the wire 33.

[0021] Please see Figure 5As shown, a first stepper motor 5 is mounted on the first guide plate 3 via a base. A first lead screw 6 is mounted on the output shaft of the first stepper motor 5. The first lead screw 6 is rotatably mounted on the inner wall of the first guide groove 4. A third guide plate 20 is mounted on the base 1. A third guide groove 21 is formed in the third guide plate 20. A third lead screw 22 is rotatably mounted on the inner wall of the third guide groove 21. The threads on the third lead screw 22 are symmetrically opposite in direction. A knob is mounted on one end of the third lead screw 22. A damping wheel 23 is mounted around the knob. Two sets of third guide blocks 24 are symmetrically assembled in the third guide groove 21. A movable plate 25 is mounted on the third guide block 24. A clamping block 26 is rotatably mounted on the movable plate 25. A motor rotor 27 is placed between the two sets of clamping blocks 26. A third stepper motor 28 is mounted on one of the movable plates 25 via a base. The output shaft of the third stepper motor 28 is fixedly connected to the rotating shaft of the clamping block 26. A fixed plate 29 is mounted on the bottom side of the base 1. A motor rotor 27 is mounted on the fixed plate 29. A support frame 30 is provided, on which a release wheel 31 is rotatably mounted. A second drive motor 32 is mounted on the support frame 30 via a base. The output shaft of the second drive motor 32 is fixedly connected to the rotating shaft of the release wheel 31. A wire 33 is wound on the release wheel 31. During operation, the existing winding device has difficulty in continuously winding the coil during the winding process of the motor rotor 27, resulting in low winding efficiency. By placing the motor rotor 27 between two sets of clamping blocks 26 and rotating the damping wheel 23, the knob is driven to rotate. The damping wheel 23 locks the stationary third lead screw 22 through the friction between itself and the third guide plate 20. The knob drives the third lead screw 22 to rotate, and the third lead screw 22 drives the two sets of third guide blocks 24 on it to move synchronously relative to each other. The two sets of third guide blocks 24 drive the two sets of moving plates 25 to move synchronously relative to each other. The two sets of moving plates 25 drive the two sets of clamping blocks 26 to move synchronously relative to each other. The two sets of clamping blocks 26 clamp and fix the motor rotor 27.

[0022] During the winding process of the motor rotor 27, the second drive motor 32 operates, driving the release wheel 31 to rotate. The release wheel 31 releases the wire 33, which then passes through the wire wheel 19, then through the wire tube 35, and finally winds onto the rotor teeth of the motor rotor 27. The third stepper motor 28 operates, driving the clamping block 26 to rotate back and forth by 5°. The clamping block 26 drives the motor rotor 27 to rotate back and forth by 5°. During this process, the control system of the control panel 2 controls the first stepper motor 5 to operate, driving the first lead screw 6 to rotate. The first lead screw 6 drives the first guide block 7 on it to move horizontally back and forth. The first guide block 7 drives the second guide plate 8 to move horizontally back and forth. The second guide plate 8 drives the second guide block 12 on it to move horizontally back and forth. 12 drives the lifting block 13 to move horizontally back and forth, the lifting block 13 drives the slider 16 to move horizontally back and forth, the slider 16 drives the guide wheel 19 to move horizontally back and forth, the guide wheel 19 pulls the guide wire 33 to move horizontally back and forth, at the same time the second guide plate 8 drives the connecting frame 34 to move horizontally back and forth, the connecting frame 34 drives the guide tube 35 to move horizontally back and forth, that is, the guide wheel 19 and the guide tube 35 move synchronously, the guide tube 35 pulls the guide wire 33 to move horizontally back and forth, and at the same time the motor rotor 27 rotates back and forth by 5°, so that the guide wire 33 is evenly wound on the motor rotor 27. After one rotor tooth is wound, the clamp 26 will drive the motor rotor 27 to rotate 45°, and then repeat the above steps. This structure can continuously and efficiently wind the motor rotor 27, which is beneficial to improving the winding efficiency.

[0023] Working principle: Existing winding devices struggle to continuously wind the coil during the winding process of the motor rotor 27, resulting in low winding efficiency. By placing the motor rotor 27 between two sets of clamps 26 and rotating the damping wheel 23, the knob is turned. The damping wheel 23, through its own friction with the third guide plate 20, locks the stationary third lead screw 22. The knob then rotates the third lead screw 22, causing the two sets of third guide blocks 24 on it to move synchronously relative to each other. The two sets of third guide blocks 24, in turn, cause the two sets of moving plates 25 to move synchronously relative to each other. For movement, two sets of moving plates 25 drive two sets of clamping blocks 26 to move synchronously relative to each other, and the two sets of clamping blocks 26 clamp and fix the motor rotor 27; during the winding process of the motor rotor 27, the second drive motor 32 operates, driving the release wheel 31 to rotate, the release wheel 31 releases the wire 33, then the wire 33 passes through the wire wheel 19, then through the wire tube 35, and finally winds around the rotor teeth of the motor rotor 27. The third stepper motor 28 operates, driving the clamping blocks 26 to reciprocate 5°, and the clamping blocks 26 drive the motor rotor 27 to reciprocate 5°. During this process, the control system of the control panel 2 controls the operation of the first stepper motor 5, which drives the first lead screw 6 to rotate. The first lead screw 6 drives the first guide block 7 on it to move horizontally back and forth. The first guide block 7 drives the second guide plate 8 to move horizontally back and forth. The second guide plate 8 drives the second guide block 12 on it to move horizontally back and forth. The second guide block 12 drives the lifting block 13 to move horizontally back and forth. The lifting block 13 drives the slider 16 to move horizontally back and forth. The slider 16 drives the guide wheel 19 to move horizontally back and forth. The guide wheel 19 pulls the guide wire 33 to move horizontally back and forth. Meanwhile, the second guide plate 8 drives the connecting frame 34 to move horizontally back and forth, and the connecting frame 34 drives the wire tube 35 to move horizontally back and forth. That is, the wire wheel 19 and the wire tube 35 move synchronously. The wire tube 35 pulls the wire 33 to move horizontally back and forth. At the same time, the motor rotor 27 rotates back and forth by 5°, so that the wire 33 is evenly wound on the motor rotor 27. After one rotor tooth is wound, the clamp 26 will drive the motor rotor 27 to rotate by 45°. Then the above steps are repeated. This structure can continuously and efficiently wind the motor rotor 27, which is beneficial to improving the winding efficiency.Existing winding devices cannot easily adjust the tension of the wire 33 during the winding process of the motor rotor 27, which easily leads to inconsistent outer diameters of the coils and poor uniformity of the wire 33. During the winding process of the motor rotor 27, because the wire wheel 19 is located between the release wheel 31 and the motor rotor 27 and is in a concave position, the wire wheel 19 is always in contact with the wire 33. When the wire 33 becomes slack, the wire wheel 19 moves vertically downwards under its own weight. The wire wheel 19 drives the slider 16 on it to move vertically downwards, and the slider 16 drives the first electrode plate 17 on it to move vertically downwards, so that the first electrode plate 17 contacts the second electrode plate 18. At this time, the internal circuit of the indicator light 14 is turned on, and the indicator light 14 sends an electrical signal to the control panel 2. After receiving the electrical signal, the control panel 2 controls the second stepper motor 10 to operate, realizing the activation of the tension adjustment component. The second stepper motor 10 drives the second lead screw 11 to rotate, and the second lead screw 11 drives the second guide on it. Block 12 moves vertically downwards, the second guide block 12 drives the lifting block 13 to move vertically downwards, the lifting block 13 drives the slider 16 on it to move vertically downwards, the slider 16 drives the guide wheel 19 on it to move vertically downwards, and the guide wheel 19, while moving vertically downwards, presses the wire 33 downwards under its own weight until the wire 33 is in a tensioned state. When the wire 33 is in a tensioned state, the wire 33 will block the guide wheel 19, and the guide wheel 19 will not continue to move downwards, causing the slider 16 to stop moving downwards, but the lifting block 13 will continue to move downwards, causing the first electrode plate 17 and the second electrode plate 18 to quickly separate, and the electrical signal of the indicator light 14 disappears. At this time, the control panel 2 controls the second stepper motor 10 to stop operating, causing the lifting block 13 to stop moving downwards, realizing the closure of the tension adjustment component. When the wire 33 becomes slack again, the above steps are repeated. This structure can automatically and conveniently adjust the tension of the wire 33, avoid inconsistent outer diameters of the coil, and help improve the neatness of the wire 33.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
