Description

Technical Field

[0001] This invention relates to the field of inductor winding machines, specifically to a core positioning mechanism for an inductor winding machine and an inductor winding machine. Background Technology

[0002] Inductors are fundamental components in electronic circuits, widely used in power management, signal filtering, and other fields. The winding process is a crucial step in their production, and the inductor winding machine is the core automated equipment for this process. The core positioning mechanism, as a core component of the winding machine, directly determines the winding quality and electrical performance of the inductor coil through its positioning accuracy and stability. During the inductor winding process, the positioning mechanism must precisely fix the core to ensure that it does not shift during winding, allowing the inductor wire to be wound evenly and tightly onto the core, meeting the performance requirements of the inductor product.

[0003] Currently, the core positioning mechanisms of existing inductor winding machines have many shortcomings. Some mechanisms are complex in structure, have a high failure rate, and use unreasonable clamping and positioning methods, making it difficult to achieve accurate core positioning. Some mechanisms use fixed clamping structures, and the clamping force cannot be adaptively adjusted, which can easily lead to problems such as the core shaking due to excessively loose clamping or damage to the core and inductor wire due to excessively tight clamping. Furthermore, the tension of the inductor wire cannot be adjusted in real time during the winding process, which can easily result in loose winding and overlapping. At the same time, most positioning mechanisms cannot achieve synchronous misalignment between the core and the winding action, resulting in low winding regularity, and the core loading and unloading operations are cumbersome, affecting production efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a core positioning mechanism for an inductor winding machine and an inductor winding machine, which solves the problems of inaccurate positioning, unstable clamping force, inability to automatically adjust inductor wire tension, poor winding quality, and cumbersome operation of existing core positioning mechanisms.

[0007] Preferably, the outer diameter of the rotating ring is provided with a winding groove, and both the internal toothed ring and the rotating ring have a section fixed to one side by bolts.

[0008] Preferably, a first motor is fixedly installed on one side of the middle portion of the arc-shaped fixing plate, and a pinion is fixedly installed on the drive end of the first motor, with one side of the pinion meshing with the inner side of the internal gear ring.

[0009] Preferably, guide rods are fixedly installed on both sides of the inner end of the positioning plate, and the outer diameters of the guide rods are respectively movably installed on the inner sides of the corresponding movable platform.

[0010] Preferably, a first driven bevel gear is fixedly installed on the inner end of the lead screw, a spindle box is fixedly installed in the middle of the machining table, and a first driving bevel gear is fixedly installed on the driving end of the spindle box. The bottom of the first driven bevel gear is meshed with the outside of the first driving bevel gear.

[0011] Preferably, bending brackets are fixedly installed at both ends of the pressure plate on one side, and the ends of the bending brackets are respectively fixedly installed on both sides of the positioning bearing seat.

[0014] Preferably, an inductor winding machine is characterized by including the core positioning mechanism of the inductor winding machine described above.

[0015] This invention provides a core positioning mechanism for an inductor winding machine and an inductor winding machine. It has the following beneficial effects: 1. This invention achieves three-point positioning of the iron core through three evenly distributed positioning plates in conjunction with a lead screw, movable table, connecting rod, and iron core positioning wheel. This ensures precise alignment between the iron core positioning center and the winding center, avoiding winding deviations caused by iron core offset during winding. Simultaneously, as the movable table continues to move inward, the pressure plate drives the rotating frame to bend via the connecting rod, and the pressure roller bends the spring plate. The reaction force of the spring plate clamps the iron core, and the pressure roller slides relative to the spring plate surface, compensating for changes in elasticity during bending, ensuring the clamping force of the iron core positioning wheel on the iron core remains stable. Even if the iron core diameter changes slightly during winding, stable clamping is maintained, avoiding iron core wobbling caused by excessively loose clamping and preventing crushing damage to the iron core and inductor wire caused by excessively tight clamping, effectively ensuring winding accuracy and product qualification rate.

[0016] 2. The tension control mechanism on the rotating ring of this invention can respond in real time to changes in the tension of the inductor wire: when the inductor wire is too tight, its force on the outer support plate causes the guide sleeve to move outward, and the outer support plate to contract inward synchronously through the cooperation of the wedge slider and the wedge groove plate, relieving the tension of the wire; when the inductor wire is too loose, the spring resets and causes the guide sleeve to move inward, and the outer support plate to expand outward, increasing the tension of the wire. This automatic tension adjustment function can ensure that the tension of the inductor wire is always in the optimal state throughout the winding process, making the winding tight and uniform, avoiding problems such as coil loosening and wire diameter damage caused by uneven wire tension, and further improving the consistency of winding quality.

[0019] The technical solutions in 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.

[0020] Example: Please see the appendix Figure 1 -Appendix Figure 8 This invention provides a core positioning mechanism for an inductor winding machine, such as... Figure 1As shown, the machining table includes a machining table 1. An arc-shaped fixing plate 2 is fixedly installed on one side of the upper surface of the machining table 1. An internal toothed ring 3 is movably arranged on the front side of the arc-shaped fixing plate 2. A rotating ring 4 is fixedly installed on the front side of the internal toothed ring 3 through a connecting frame. A tension control mechanism 9 is provided on one side of the inner side of the rotating ring 4. Three positioning plates 13 are evenly fixedly installed on the top of the machining table 1. A lead screw 14 is movably installed in the middle of the inner end of each positioning plate 13. A movable table 16 is threadedly connected to the outer diameter of each lead screw 14. A rotating table 16 is movably installed at both the upper and lower ends of the movable table 16. Spring plates 18 are fixedly installed on both sides of the inner side of the frame 17 and the movable platform 16, and the ends of the spring plates 18 extend into the interior of the corresponding rotating frame 17. Pressure rollers 19 are fixedly installed on one side of the inner wall of the rotating frame 17, and the inner ends of the pressure rollers 19 abut against the surface of the corresponding spring plates 18. Connecting rods 20 are movably installed on the inner end of the rotating frame 17, and the ends of the connecting rods 20 are movably installed on both sides of the pressure plate 21. Vertical shafts 22 are movably installed on the top of the pressure plate 21, and iron core positioning wheels 23 are fixedly installed on the top of the vertical shafts 22.The machining table 1 serves as the mounting base for the entire positioning mechanism, providing stable mounting support for all components and ensuring that the mechanism does not shake during operation, thus guaranteeing the stability of positioning and winding. The arc-shaped fixing plate 2 is fixed on the machining table 1, and its arc-shaped structure matches the shape of the internal gear ring 3 and the rotating ring 4, providing initial limiting and guiding functions for the internal gear ring 3 and the rotating ring 4, facilitating their stable rotation around the arc-shaped fixing plate 2. The internal gear ring 3 is movably positioned on the front side of the arc-shaped fixing plate 2 and is the core transmission component that drives the rotation of the rotating ring 4. It transmits power through meshing with the drive component, thereby driving the rotating ring 4. 4. Synchronous rotation; the rotating ring 4 is fixedly connected to the internal gear ring 3 through the connecting frame, and can rotate together with the internal gear ring 3. Its internal tension control mechanism 9 is used to adjust the tension of the inductor wire in real time during the winding process to ensure the winding quality; three positioning plates 13 are evenly fixed on the top of the processing table 1, symmetrically distributed, providing a mounting carrier for components such as the lead screw 14 and guide rod 15, while ensuring the synchronicity of the three positioning structures; the lead screw 14 is movably installed in the middle of the inner end of the positioning plate 13, and drives the movable table 16 to reciprocate through rotational movement, thereby driving the subsequent positioning components to complete the clamping and positioning of the iron core; the movable table 16 and the lead screw 14 are threaded together. The connector serves as an intermediate carrier connecting the lead screw 14 and the positioning actuator. The rotating frame 17 mounted at its upper and lower ends can rotate flexibly, working in conjunction with the spring plate 18 to adjust the clamping force. The spring plate 18 is fixed to both sides inside the movable table 16, with its ends extending into the rotating frame 17. It can bend under the action of the rotating frame 17, generating a reaction force to provide a stable clamping force for the iron core positioning wheel 23. The pressure roller 19 is fixed to one side of the inner wall of the rotating frame 17, abutting against the surface of the spring plate 18. When the rotating frame 17 bends, the pressure roller 19 slides relative to the surface of the spring plate 18, compensating for changes in the elastic force during the bending process of the spring plate 18. To ensure a stable clamping force, the connecting rod 20 connects the rotating frame 17 and the pressure plate 21, transmitting the movement of the movable table 16 to the pressure plate 21, causing the pressure plate 21 to move synchronously. The pressure plate 21 serves as the mounting carrier for the vertical shaft 22, enabling it to move together with the iron core positioning wheel 23, thus achieving positioning and clamping of the iron core. The vertical shaft 22 is movably mounted on the top of the pressure plate 21, allowing it to rotate flexibly and drive the iron core positioning wheel 23 to rotate synchronously. The iron core positioning wheel 23 is fixed to the top of the vertical shaft 22, and its outer diameter is used to abut against the surface of the iron core, achieving positioning and clamping of the iron core. At the same time, it can drive the iron core to rotate synchronously through rotation, achieving staggered winding.

[0021] In this embodiment, a number of guide shafts 5 are evenly and movably installed on the front end of the arc-shaped fixing plate 2. A first limiting wheel 6 is fixedly installed on the outer diameter of one side of the guide shaft 5. The inner diameter of the first limiting wheel 6 is in contact with the outer diameter of the internal tooth ring 3. A second limiting wheel 7 is fixedly installed on the outer diameter of the other side of the guide shaft 5. The inner diameter of the second limiting wheel 7 is in contact with the outer diameter of the rotating ring 4. The guide shaft 5 is evenly and movably mounted on the front end of the arc-shaped fixed plate 2, allowing for flexible rotation. It provides mounting support for the first limiting wheel 6 and the second limiting wheel 7, and can also adapt to the rotation of the internal gear ring 3 and the rotating ring 4, reducing friction between components. The first limiting wheel 6 is fixed on one side of the outer diameter of the guide shaft 5, and its inner diameter fits against the outer diameter of the internal gear ring 3. It can limit and guide the internal gear ring 3, preventing radial displacement during rotation and ensuring that the internal gear ring 3 always rotates around a fixed trajectory. At the same time, it reduces the friction force during the rotation of the internal gear ring 3, ensuring smooth transmission. The second limiting wheel 7 is fixed on the other side of the outer diameter of the guide shaft 5, and its inner diameter fits against the outer diameter of the rotating ring 4. It cooperates with the first limiting wheel 6 to limit and guide the rotating ring 4, preventing displacement during rotation and ensuring that the rotating ring 4 rotates synchronously with the internal gear ring 3. This avoids winding deviation caused by the displacement of the rotating ring 4, thereby ensuring winding quality. Several guide shafts 5, the first limiting wheel 6 and the second limiting wheel 7 are evenly distributed, which can limit the internal gear ring 3 and the rotating ring 4 in all directions, further improving the stability of the mechanism operation.

[0022] Furthermore, a winding groove 8 is provided on the outer diameter of the rotating ring 4, and a section 10 is fixed to one side of both the internal gear ring 3 and the rotating ring 4 by bolts. The winding groove 8 is provided on the outer diameter of the rotating ring 4 to accommodate the inductor wire. During the winding process, the inductor wire can be arranged in an orderly manner along the winding groove 8, avoiding tangling and confusion, and ensuring the regularity of the winding. The section 10 is fixed to one side of the internal gear ring 3 and the rotating ring 4 by bolts, and can be opened or closed as needed. When the section 10 is opened, the iron core to be wound can be quickly placed into the internal gear ring 3 and the rotating ring 4. After the section is closed, it is tightened by bolts to restore the internal gear ring 3 and the rotating ring 4 to a complete ring structure, ensuring stable rotation. This design greatly simplifies the loading and unloading of the iron core, saves processing preparation time, and improves processing efficiency. The bolt connection method not only ensures the firmness of the connection between the section 10 and the internal gear ring 3 and the rotating ring 4, but also facilitates disassembly and installation, making subsequent maintenance and repair convenient.

[0023] Furthermore, a first motor 11 is fixedly installed on one side of the middle portion of the arc-shaped fixing plate 2. A pinion 12 is fixedly installed on the drive end of the first motor 11, and one side of the pinion 12 is meshed with the inner side of the internal gear ring 3. The first motor 11 is fixed on one side of the middle portion of the arc-shaped fixing plate 2, serving as a power source to drive the internal gear ring 3 and the rotating ring 4 to rotate. It can provide stable driving force to ensure the continuous and stable progress of the winding process. The pinion 12 is fixed on the drive end of the first motor 11 and meshes with the inner side of the internal gear ring 3, transmitting the rotational power of the first motor 11 to the internal gear ring 3. Through the gear meshing transmission method, the transmission efficiency is high and the stability is good, ensuring that the internal gear ring 3 rotates smoothly at the set speed, thereby driving the rotating ring 4 to rotate synchronously, realizing the winding of the inductor wire on the iron core. The gear meshing method can also achieve precise speed control, making it easy to adjust the rotational speed of the rotating ring 4 according to the winding requirements, improving the controllability of the winding quality.

[0024] Furthermore, guide rods 15 are fixedly installed on both sides of the inner end of the positioning plate 13. The outer diameters of the guide rods 15 are movably installed on the inner sides of the corresponding movable platform 16. The guide rods 15 are fixed on both sides of the inner end of the positioning plate 13 and are arranged parallel to the lead screw 14. Their outer diameters are movably installed on the inner sides of the movable platform 16, which limit and guide the movement of the movable platform 16, preventing the movable platform 16 from rotating with the lead screw 14 when the lead screw 14 rotates. This ensures that the movable platform 16 can only make reciprocating linear movements along the axis of the lead screw 14 and the guide rods 15, thereby ensuring that the movable platform 16 drives the subsequent positioning components to move smoothly and achieve accurate positioning of the iron core. At the same time, the guide rods 15 can also share the force on the lead screw 14, reduce the wear of the lead screw 14, extend the service life of the lead screw 14, and ensure the long-term stable operation of the mechanism. The two guide rods 15 are symmetrically distributed on both sides of the lead screw 14, which can make the force on the movable platform 16 more even, avoid the movable platform 16 from tilting during movement, and further improve the positioning accuracy.

[0025] Furthermore, a first driven bevel gear 24 is fixedly installed on the inner end of the lead screw 14. A spindle box is fixedly installed in the middle of the machining table 1, and a first driving bevel gear 25 is fixedly installed on the drive end of the spindle box. The bottom of each of the first driven bevel gears 24 is meshed with the outer side of the first driving bevel gear 25. The first driven bevel gear 24 is fixed on the inner end of the lead screw 14 and serves as an intermediate component for power transmission. It can transmit the rotational power of the first driving bevel gear 25 to the lead screw 14, causing the lead screw 14 to rotate. The spindle box is fixed in the middle of the machining table 1 and integrates a drive component inside. It can provide a stable driving force for the first driving bevel gear 25 and facilitate the adjustment of the rotational speed and direction of the first driving bevel gear 25, thereby adjusting the rotational speed of the lead screw 14 and the moving speed of the movable table 16. The first driving bevel gear 25 is fixed on the drive end of the spindle box, and its outer side is meshed with the three first driven bevel gears. All three driven bevel gears 24 are meshed and connected, enabling them to rotate synchronously and simultaneously, which in turn drives the three lead screws 14 to rotate synchronously. This ensures that the three movable tables 16 move synchronously inward or outward, achieving synchronous clamping and releasing of the iron core by the three iron core positioning wheels 23. This ensures the symmetry and accuracy of the iron core positioning, avoids iron core offset caused by asynchronous movement of a single positioning wheel, and thus guarantees the winding quality. The bevel gear meshing transmission method can change the direction of power transmission, making the drive direction of the spindle box match the rotation direction of the lead screw 14, optimizing the layout of the mechanism and making the overall structure more compact.

[0026] Furthermore, bending brackets 26 are fixedly installed at both ends of one side pressure plate 21, and the ends of bending brackets 26 are fixedly installed on both sides of positioning bearing seat 27. A sleeve 28 is fixedly installed on the inner ring of positioning bearing seat 27, and a second driving bevel gear 29 is fixedly installed on the inner end of sleeve 28. A second driven bevel gear 30 is fixedly installed on the outer diameter of one side vertical shaft 22, and the second driven bevel gear 30 meshes with the inner end of the second driving bevel gear 29. The bending bracket 26 is fixed to both ends of one side pressure plate 21, and its ends are fixed to both sides of the positioning bearing seat 27. It is used to fix the positioning bearing seat 27 to the pressure plate 21, so that the positioning bearing seat 27 can move with the pressure plate 21. This ensures that the subsequent transmission components can move synchronously during the movement of the iron core positioning wheel 23, and avoids transmission disengagement. The inner ring of the positioning bearing seat 27 is fixedly installed with a sleeve 28, which can provide stable support for the sleeve 28, while allowing the sleeve 28 to rotate flexibly, reducing the friction force when the sleeve 28 rotates, and ensuring the smoothness of transmission. The sleeve 28 serves as an intermediate carrier for power transmission. The second driving bevel gear 29 fixed to its inner end can transmit power to the second driven bevel gear 3. 0; The second driving bevel gear 29 meshes with the second driven bevel gear 30, which can transmit the rotational power of the sleeve 28 to the vertical shaft 22, causing the vertical shaft 22 to rotate, and then driving the iron core positioning wheel 23 to rotate; The second driven bevel gear 30 is fixed on the outer diameter of one side of the vertical shaft 22, which can transmit power to the vertical shaft 22. At the same time, through the friction between the iron core positioning wheel 23 and the iron core, the iron core is driven to rotate synchronously, realizing the synchronous misalignment movement of the iron core and the rotating ring 4, completing the misaligned winding, and improving the regularity and inductance performance of the winding; This transmission structure is reasonably designed, which can ensure the stability and accuracy of power transmission, and at the same time adapt to the movement of the iron core positioning wheel 23, avoiding transmission failure due to the movement of the positioning wheel.

[0027] Furthermore, a second motor 31 is fixedly installed on the upper part of one side positioning plate 13. A rotating shaft 32 is fixedly installed on the drive end of the second motor 31, and the end of the rotating shaft 32 extends into the interior of the sleeve 28. Splines 33 are fixedly installed on both ends of the rotating shaft 32. Keyways 34 are opened on both sides of the interior of the sleeve 28, and the outer ends of the splines 33 are movably installed with the interior of the corresponding side keyways 34. The second motor 31 is fixed on the upper part of one side positioning plate 13 and serves as the power source for driving the vertical shaft 22 and the iron core positioning wheel 23 to rotate. It can provide stable driving force and facilitate the adjustment of the rotation speed of the iron core positioning wheel 23 to adapt to different winding requirements. The rotating shaft 32 is fixed on the drive end of the second motor 31, and its end extends into the interior of the sleeve 28 to transmit the rotational power of the second motor 31 to the sleeve 28. Splines 33 are fixed on both ends of the rotating shaft 32, and keyways 34 are opened on both sides of the interior of the sleeve 28. The splines 33 are movably installed in the keyways 34. Internally, this spline connection can transmit the rotational power of the rotating shaft 32 to the sleeve 28, causing the sleeve 28 to rotate synchronously, and also allows the sleeve 28 to reciprocate along the axial direction of the rotating shaft 32, adapting to the movement of the pressure plate 21 and the positioning bearing seat 27, ensuring that the power transmission is not interrupted during the movement of the iron core positioning wheel 23; the high precision of the spline and keyway 34 can ensure the smoothness of power transmission, avoid slippage, jamming and other situations, ensure the stability of the rotation of the iron core positioning wheel 23, and thus ensure the smooth progress of misaligned winding.

[0028] Furthermore, the tension control mechanism 9 includes a mounting plate 901, which is fixedly mounted on one side of the rotating ring 4. A guide shaft 902 is fixedly mounted on the bottom side of the mounting plate 901. The end of the guide shaft 902 is movably mounted inside the guide sleeve 903. The inner end of the guide sleeve 903 is connected to the mounting plate 901 by a spring 904. Multiple outer support plates 905 are provided around the guide sleeve 903. Several wedge-shaped sliders 906 are uniformly fixedly mounted on the outer diameter of the guide sleeve 903. A wedge-shaped slide plate 907 is fixedly mounted at the inner end of the outer support plate 905 at a position corresponding to each wedge-shaped slider 906. The outer ends of the wedge-shaped sliders 906 are movably mounted inside the corresponding wedge-shaped slide plate 907. Mounting plate 901 is fixed to one side of rotating ring 4, serving as the mounting carrier for all components of tension control mechanism 9. This ensures that tension control mechanism 9 can rotate with rotating ring 4, allowing for real-time tension adjustment of the inductor wire. Guide shaft 902 is fixed to one side of the bottom of mounting plate 901, with its end movably mounted inside guide sleeve 903. This guide shaft limits and guides the movement of guide sleeve 903, ensuring that guide sleeve 903 can only reciprocate along the axial direction of guide shaft 902, preventing deviation and ensuring the stability of tension adjustment. Guide sleeve 903 serves as the tensioning... The core adjustment component can move to retract or expand the outer support plate 905, thereby adjusting the tension of the inductor wire. The spring 904 connects the inner end of the guide sleeve 903 to the mounting plate 901, providing a reset force for the guide sleeve 903. When the inductor wire is too loose, the spring force of the spring 904 pushes the guide sleeve inward, causing the outer support plate 905 to expand and increase the tension of the inductor wire. When the inductor wire is too tight, the force of the inductor wire pushes the guide sleeve outward, compressing the spring 904 and causing the outer support plate 905 to retract, relieving the tension of the inductor wire and achieving automatic tension adjustment. Section; the outer support plate 905 is set around the guide sleeve 903 for contact with the inductor wire. It adjusts the tension of the inductor wire by its own contraction and expansion. Multiple outer support plates 905 are evenly distributed, ensuring omnidirectional contact with the inductor wire and uniform adjustment effect. The wedge-shaped slider 906 is fixed on the outer diameter of the guide sleeve 903, and the wedge-shaped slide plate 907 is fixed on the inner end of the outer support plate 905, corresponding to the wedge-shaped slider 906. The wedge-shaped slider 906 is movably disposed inside the wedge-shaped slide plate 907. When the guide sleeve 903 moves along the guide shaft 902, the wedge-shaped slider 906 will... The wedge-shaped sliding plate 907 slides internally, utilizing the characteristics of the wedge structure to convert the axial movement of the guide sleeve 903 into the radial movement of the outer support plate 905, realizing the synchronous contraction or expansion of the outer support plate 905, ensuring that the adjustment range of all outer support plates 905 is consistent, thereby ensuring that the tension of the inductor wire is uniform at all positions, avoiding winding quality problems caused by uneven tension in some areas; the entire tension control mechanism 9 has a compact structure and sensitive adjustment, and can respond to changes in the tension of the inductor wire in real time, ensuring that the inductor wire is in the optimal tension state throughout the winding process, thus improving the winding quality.

[0029] Furthermore, an inductor winding machine includes the core positioning mechanism of the aforementioned inductor winding machine.

[0030] Working principle: First, open the broken section 10 of the internal gear ring 3 and the rotating ring 4, and place one side of the iron core to be wound inside it. Then close the broken section 10 and use the screw to fix it so that the internal gear ring 3 and the rotating ring 4 are complete. Then start the spindle box, which drives the first driving bevel gear 25 to rotate, driving the three first driven bevel gears 24 and the lead screw 14 to rotate. When the lead screw 14 rotates, the guide rod 15 limits the movement of all the movable tables 16 inward. When the movable tables 16 move, they will drive the pressure plate 21 to move together through the connecting rod 20, thereby driving the vertical shaft 22 and the iron core positioning wheel 23 to move inward in sync until the outer diameter of the three iron core positioning wheels 23 all abuts against the outer diameter of the iron core to be wound. At this time, the movable tables 16 continue to move inward, and the pressure plate 21 will move inward through the connecting rod 20. The rotating frame 17 bends as it bends, and the pressure roller 19 bends the spring plate 18. The reaction force generated by the bent spring plate 18 causes all the core positioning wheels 23 to clamp and position the core. When the pressure roller 19 bends the spring plate 18, it slides relative to the surface of the spring plate 18, causing the lever arm of the bent spring plate 18 to change. This compensates for the change in elastic force as the degree of bending of the spring plate 18 changes, keeping the elastic force of the spring plate 18 stable. As a result, the clamping force of the three core positioning wheels 23 on the core remains stable. During subsequent winding, even if the diameter and length of the core change during winding, a stable clamping force can be maintained without damaging the core and inductor wire, thus improving the winding quality.

[0031] After clamping and positioning are completed, one end of the inductor wire in the winding groove 8 is pulled out, passes around the tension control mechanism 9, and is fixed on the iron core. At this time, the first motor 11 and the second motor 31 are started. The first motor 11 drives the pinion 12 to rotate. The rotating pinion 12 meshes with the internal gear ring 3, driving the internal gear ring 3 and the rotating ring 4 to rotate. When the rotating ring 4 rotates, since one end of the inductor wire is already fixed on the iron core, the inductor wire will wind around the iron core as the rotating ring 4 rotates. At the same time, the second motor 31 drives the rotating shaft 32 to rotate. Under the limiting action of the spline 33 and the keyway 34, the sleeve 28 rotates and the second driving bevel gear 29 rotates. The second driving bevel gear 29 drives the second driven bevel gear 30 and the vertical shaft 22 to rotate, thereby driving the iron core positioning wheel 23 to rotate. When the iron core positioning wheel 23 rotates, the iron core will rotate slowly through friction, thereby realizing the staggered winding operation.

[0032] During the winding process, the inductor wire passes through the outer support plate 905 on the tension control mechanism 9. When the inductor wire is too tight, it applies force to the outer support plate 905. Under the limiting action of the wedge slider 906 and the wedge groove plate 907, the guide sleeve 903 moves outward, causing all the outer support plates 905 to contract inward synchronously, reducing the tension of the inductor wire. When the inductor wire is too loose, under the action of the spring 904, the guide sleeve 903 moves inward, causing all the outer support plates 905 to expand outward, increasing the tension of the inductor wire, so that the inductor wire is tightly wound on the iron core.
