[0015] Compared with the prior art, the present invention has at least the following beneficial effects: 1. The fully automatic winding device for the hollow cup motor coil in the present invention includes a sliding platform, a flying fork motion assembly, a core shaft adjustment assembly, a die head drive assembly, a copper wire guide assembly and a rotating winding assembly, wherein the sliding platform 1 serves as the basic support platform of the entire winding device, providing a stable installation foundation for other components. The sliding platform itself can slide, so that the position of the entire winding device can be adjusted as needed during operation to adapt to the winding requirements of hollow cup motor coils of different sizes and specifications; the rotation and swing of the flying fork motion assembly 2 are used to control the rhythm and trajectory of the copper wire winding, and the rotating seat in the flying fork motion assembly is installed on the sliding platform, and the first drive assembly is installed on the rotating seat to provide power for the rotation of the rotating spindle; the rotating spindle is rotatably installed on the rotating seat, so that the rotating spindle can rotate flexibly on the rotating seat; the first flying fork is sleeved on the side of the rotating spindle away from the rotating seat, and the first drive assembly is suitable for driving the rotating spindle to rotate, and driving the first flying fork to rotate together, thereby realizing the winding action of the copper wire; the driving cylinder in the core shaft adjustment assembly is installed on the top of the rotating seat, and the driving cylinder drives the threading core shaft component to slide in the center hole of the rotating spindle through the first side support component and the second side support component. In this way, the telescopic movement of the driving cylinder drives the movement of the first and second side support components, allowing the threading mandrel component to slide within the center hole of the rotating main shaft. The threading mandrel component provides a threading channel for the copper wire and can be adjusted within the rotating main shaft as needed. To achieve stable rotation of the die head and adjust the rotation speed and angle as needed, the third servo motor of the die head drive assembly is installed on one side of the rotating base. The die head rotating sleeve is installed on the end of the rotating main shaft away from the threading mandrel component. By coordinating the rotation of the die head with the rotation of the flying fork motion assembly, a complete winding method is formed, which improves the winding accuracy and efficiency. At the same time, the sprocket drive method can ensure the stability and reliability of power transmission; the copper wire in the copper wire guide assembly is guided out of the threading mandrel component through the first guide assembly, the second guide assembly, and the third guide assembly. Through the joint guidance of the first guide assembly, the second guide assembly and the third guide assembly, the copper wire can be smoothly guided from the inside of the threading core shaft component to the outside, preparing for the subsequent winding operation; the rotating winding assembly is the core component for directly winding the copper wire, and it winds the copper wire guided out of the outside of the threading core shaft component to finally form a hollow cup motor coil.

[0016] 2. Through the sliding function of the sliding platform, the overall position of the winding device can be accurately controlled, thereby improving the accuracy and flexibility of winding. When winding coils of different sizes, it can be quickly adjusted to the appropriate position, reducing manual intervention and improving production efficiency and product quality. The flying fork motion assembly enables the winding device to achieve high-speed and stable rotational motion. Through the precise control of the first drive assembly, the speed and rotation angle of the rotating spindle can be guaranteed to be accurate, thereby improving the quality and efficiency of winding. The core shaft adjustment assembly can flexibly adjust the position of the threading core shaft component according to actual winding requirements. When winding hollow cup motor coils of different specifications, the position of the threading core shaft component can be quickly changed through the control of the drive cylinder, thereby adjusting the threading path and winding starting point of the copper wire, improving the adaptability of the device and the flexibility of winding. The design of the copper wire guide assembly ensures the smoothness and stability of the copper wire during the winding process. Through the guidance of multiple guide assemblies, the copper wire can be prevented from being entangled or twisted during the threading and winding process, thereby improving the arrangement and winding quality of the copper wire. The setting of the rotating winding assembly must have high-precision winding capabilities and can automatically wind according to preset parameters (such as the number of winding coils, winding tension, etc.). The control accuracy of winding speed and winding tension directly impacts the quality and performance of coreless motor coils. This fully automatic winding device for coreless motor coils achieves fully automated winding of coreless motor coils through the coordinated operation of various components. Its design significantly improves winding accuracy, efficiency, and flexibility, meeting the demand for high-quality, efficient production of coreless motor coils.

[0017] 3. By combining the rotary winding assembly with the flying fork winding method, the coil can be wound continuously, solving the technical problem of existing hollow cup motors that require continuous winding of multiple sets of coils. Compared with the existing manual winding method, this method not only ensures the quality and consistency of the coils, but also significantly improves efficiency. In addition, the structural design of the rotary winding assembly shortens the connecting wire between adjacent sets of coils, meeting the requirements of micro hollow cup motors that multiple sets of coils must be continuous and the connecting wire must not be too long.

[0018] 4. By combining the flying fork winding and the flat winding method, the flying fork winding method utilizes the synchronous movement of the first side sprocket transmission structure and the second side sprocket transmission structure to achieve the situation where the first flying fork on the rotating main shaft rotates while the die head does not rotate; at the same time, the first side sprocket transmission structure and the second side sprocket transmission structure are synchronously controlled to prevent the first flying fork on the rotating main shaft from rotating, while the added third servo motor drives the second main shaft drive pulley in the first side sprocket transmission structure to a state where only the die head rotates. At the same time, the threading tube in the mandrel adjustment assembly is used to push the round head ejection piece to move, thereby pressing the winding mandrel tooling to prevent the die head rotation from driving the threading tube in the mandrel adjustment assembly to rotate. This winding method can achieve continuous winding without interruption, and the connecting wires between each group of coils are short, meeting the requirements of fully automated winding of small hollow cup motor coils.

In this way, the second sprocket transmission component 42 can achieve efficient power transmission. The cooperation between the second sprocket 421 and the second chain belt 422 can ensure the synchronization and reliability of power transmission, reducing slippage and energy loss during the power transmission process.

[0045] See also Figure 12As shown, the transition sprocket assembly 43 includes a connecting rod 431, a first side sprocket transmission structure 432, and a second side sprocket transmission structure 433. The inert connecting rod 431 is rotatably mounted on the side of the first flyer 24 away from the rotating main shaft 23. One end of the inert connecting rod 431 is drivingly connected to one side of the first side sprocket transmission structure 432, and the other end of the inert connecting rod 431 is drivingly connected to one side of the second side sprocket transmission structure 433. The other sides of the first side sprocket transmission structure 432 and the second side sprocket transmission structure 433 are sleeved on the rotating main shaft 23, enabling further transmission and distribution of power. The rotation of the inert connecting rod 431 transmits power from the second sprocket transmission assembly 42 to the die head 44. This arrangement makes power transmission more flexible and can adapt to complex mechanical structures and spatial layouts. At the same time, the sprocket transmission structures on both sides ensure symmetry and balance in power transmission, improving the rotational stability of the die head 44.

[0046] See also Figure 12 As shown, the first side sprocket transmission structure 432 includes a second main shaft drive pulley 4321, a third chain belt 4322, and a third sprocket 4323. The second main shaft drive pulley 4321 is sleeved on the rotating main shaft 23, and the third sprocket 4323 is connected to one end of the inertial connecting rod 431. One side of the third chain belt 4322 meshes with the third sprocket 4323 for transmission, and the other side of the third chain belt 4322 meshes with the second main shaft drive pulley 4321 for transmission. The second main shaft drive pulley 4321 and the first main shaft drive pulley 423 are coaxially connected in parallel. In this way, the first side sprocket transmission structure 432 can achieve efficient power transmission from the inertial connecting rod 431 to the rotating main shaft 23. The cooperation between the third sprocket 4323 and the third chain belt 4322 ensures the synchronization and reliability of power transmission. The coaxially parallel connection of the second main shaft drive pulley 4321 and the first main shaft drive pulley 423 makes the power transmission more compact and reasonable, reduces the space occupied, and improves the integration of the device.

[0047] The second side sprocket transmission structure 433 includes a third main shaft drive pulley 4331, a fourth chain belt 4332, and a fourth sprocket 4333.

The symmetrical distribution of the sprocket transmission structures on both sides ensures more uniform power distribution to the rotating main shaft 23, reduces vibration and oscillation during rotation, and improves the rotation accuracy of the die head 44.

[0048] The die head 44 is rotatably mounted on the end of the rotating spindle 23 away from the core shaft adjustment assembly 3 via an angular contact ball bearing 441 and a second locking member 442. The end face of the die head 44 near the first flyer 24 is fixedly connected to the third spindle drive pulley 4331. This mounting method of the die head 44 ensures its stability and precision during high-speed rotation. The angular contact ball bearing 441 can withstand large radial and axial loads, reducing friction and wear during rotation and extending the service life of the die head 44. At the same time, the fixed connection between the die head 44 and the third spindle drive pulley 4331 ensures direct and efficient power transmission, improving the efficiency and quality of winding.

[0049] Specifically, see Figure 9 As shown, the core shaft adjustment assembly 3 also includes a round head ejector 35 and a winding core shaft tooling 36, wherein the round head ejector 35 is inserted into the end of the threading tube 341 close to the die head 44, and the winding core shaft tooling 36 is slidably connected to the sliding hole of the die head 44. A first spring 361 is sleeved on the outer circumference of the winding core shaft tooling 36, and one end of the first spring 361 abuts against the inner side wall of the die head 44, and the other end abuts against the end face of the rotating main shaft 23. The round head ejector 35 is suitable for pressing on the end face of the winding core shaft tooling 36.

[0050] In this embodiment, the rounded ejector 35 is primarily used to precisely press the winding mandrel fixture 36. During the winding process, the pressing action of the rounded ejector 35 ensures that the winding mandrel fixture 36 maintains a stable position within the sliding hole of the die head 44, preventing displacement or shaking during high-speed rotation and winding. This precise pressure control helps improve winding accuracy and stability, ensuring consistent coil quality.

[0051] The sliding connection of the winding mandrel fixture 36 allows for adjustment within the sliding hole of the die head 44 to accommodate the winding requirements of coreless motor coils of varying specifications. The first spring 361 provides an elastic support for the winding mandrel fixture 36, allowing it to deform elastically when pressed by the round-head ejector 35, thereby achieving more flexible adjustment and cushioning. This elastic support helps reduce coil quality issues caused by mechanical shock or vibration during the winding process, improving winding stability and reliability.

[0052] Specifically, see Figure 9 As shown, the second guide assembly 52 includes a second flying fork 521 and a second guide wheel 522. The second flying fork 521 is connected to the first flying fork 24, and the second guide wheel 522 is installed on the second flying fork 521. The second guide wheel 522 is suitable for guiding the copper wire 54 pulled out by the first guide wheel 512.

[0053] The third guide assembly 53 includes a third flying fork 531, a third guide wheel 532 and a tungsten steel guide needle 533. The third flying fork 531 is rotatably connected to the end of the second flying fork 521 away from the first flying fork 24. The third guide wheel 532 is installed at one end of the third flying fork 531, and the tungsten steel guide needle 533 is installed at the other end of the third flying fork 531. The copper wire 54 pulled out by the second guide wheel 522 is pulled onto the rotating winding assembly 6 in sequence through the third guide wheel 532, the third flying fork 531 and the tungsten steel guide needle 533.

[0054] Specifically, in this embodiment, the connection between the second flyer 521 and the first flyer 24 must ensure sufficient strength and stability to withstand the tension generated by the copper wire 54 during the winding process. Furthermore, the second flyer 521 allows for a certain degree of adjustability, so that the position and angle of the second guide wheel 522 can be adjusted as needed to accommodate copper wires 54 of different specifications and winding paths.

[0055] The second guide assembly 52 cooperates closely with the first guide assembly 51 to form a continuous guide path. This collaborative working mode can ensure that the copper wire 54 always maintains the correct path during the winding process, avoids problems such as entanglement and twisting, and improves the neatness and quality of the winding.

[0056] The rotatable connection of the third flying fork 531 increases the system's flexibility and adaptability. It can be adjusted to a certain angle during the winding process to accommodate the winding requirements of coreless motor coils of varying sizes and shapes. This rotatability helps reduce the bending radius of the copper wire 54 during the guiding process, preventing stress concentration caused by excessive bending in the wire 54 and affecting coil quality.

[0057] The combination of the third guide wheel 532 and the tungsten steel guide pin 533 provides precise guidance for the copper wire 54. The third guide wheel 532 continues to guide the copper wire 54, ensuring it follows the intended path. The tungsten steel guide pin 533, with its high hardness and wear resistance, provides a stable support point for the copper wire 54, ensuring it is accurately pulled onto the rotating winding assembly 6. The tungsten steel guide pin 533 must be able to withstand the friction and pressure generated by the copper wire 54 during high-speed winding to maintain accurate and stable guidance.

[0058] The third guide assembly 53, the final link in the entire copper wire 54 guidance system, forms a complete guide path together with the preceding guide assembly. This multi-stage guidance design ensures smooth flow of the copper wire 54 throughout the winding device, reducing wear and deformation of the copper wire 54 and improving winding efficiency and quality. Furthermore, the flexible adjustment capabilities of the third guide assembly 53 enable the entire device to adapt to the production needs of hollow cup motor coils of different specifications and models, enhancing the device's versatility.

[0059] Thus, during the winding process, the copper wire 54 is guided by the first guide wheel 512, the second guide wheel 522, the third guide wheel 532 and the tungsten steel guide needle 533 in sequence, and finally reaches the rotating winding assembly 6 for winding. This multi-stage guidance can ensure that the copper wire 54 is accurately guided and controlled at each link, avoiding problems such as offset, entanglement and twisting of the copper wire 54 during movement. At the same time, the reasonable layout and close coordination between the various guide components make the guiding path of the copper wire 54 smoother and more stable, reducing the friction and energy loss of the copper wire 54 during the guiding process, and improving the efficiency and quality of the winding. In addition, the adjustability and flexibility of the second guide assembly 52 and the third guide assembly 53 enable the entire device to quickly adapt to the production needs of hollow cup motor coils of different specifications and models, reducing the time and cost of equipment adjustment, and improving production efficiency and the market competitiveness of the enterprise.

[0060] Specifically, see Figure 1 、 13 As shown in FIG. 14 , the rotary winding assembly 6 includes a support base 61 , a fourth servo motor 62 , a gear transmission structure 63 , a winding component 64 and a wire guide component 65 , wherein: The support seat 61 is installed on the base 11, providing a stable installation foundation for the rotating winding assembly 6. In this embodiment, the support seat 61 includes a connecting plate 611 and a vertical bottom plate 612. The connecting plate 611 is located on the base 11, and the vertical bottom plate 612 is fixedly connected to the connecting plate 611, forming a stable support structure.

[0061] The winding component 64 is mounted on one side of the top of the support base 61, the wire guide component 65 is mounted on the winding component 64, one end of the gear transmission structure 63 is drivingly connected to the fourth servo motor 62, and the other end is drivingly connected to the winding component 64; The fourth servo motor 62 provides a power source for rotating the winding assembly 6. The fourth servo motor 62 is fixedly connected to one side of the winding component 64 through a fourth motor mounting base 621. The gear transmission structure 63 includes a first indexing gear 631, an intermediate gear 632, and a transmission sun gear 633. The first indexing gear 631 is mounted on the output shaft of the fourth servo motor 62, the intermediate gear 632 is rotatably mounted on the winding component 64, and the transmission sun gear 633 is rotatably mounted on the winding component 64. One side of the intermediate gear 632 meshes with the first indexing gear 631 for transmission, and the other side meshes with the transmission sun gear 633 for transmission. In this way, the gear transmission structure 63 is used to achieve efficient power transmission and precise speed control. Through the meshing transmission between the gears, the power of the fourth servo motor 62 can be accurately transmitted to the triangular winding fixture 642, achieving its rotational motion. The transmission sun gear 633 is mounted at the bottom end of the triangular winding fixture 642 and connected to the gear transmission structure 63, achieving power transmission. This transmission connection method ensures the stability and reliability of the transmission, ensuring the normal operation of the triangular winding fixture 642.

[0062] It is important to note that gear transmission has the advantages of high transmission precision and strong torque carrying capacity, which can ensure the stability and reliability of the winding process. At the same time, by properly designing the gear ratio, different winding speeds and torque outputs can be achieved to meet the requirements of different winding processes.

[0063] The winding component 64 includes a four-corner tool mounting seat 641 and a triangular winding tool 642. The four-corner tool mounting seat 641 is installed on one side of the vertical base plate 612, and the triangular winding tool 642 is vertically rotatably mounted on the four-corner tool mounting seat 641. The transmission sun gear 633 is installed at the bottom end of the triangular winding tool 642. The four-corner tool mounting seat 641 provides a stable installation base for the triangular winding tool 642. Its structural design needs to consider strength, rigidity and adjustability. The triangular structure of the triangular winding tool 642 can provide multiple winding positions, improving the flexibility and efficiency of winding. The rotational motion of the triangular winding tool 642 is used to achieve the winding of the copper wire 54. By precisely controlling its rotation speed and angle, the winding quality and dimensional accuracy of the coil can be guaranteed. At the same time, the triangular winding tool 642 should also be considered to facilitate the removal and replacement of the coil to improve production efficiency.

[0064] In this embodiment, the support seat 61 needs to be able to withstand the various forces and torques generated during the winding process. For this purpose, the support seat 61 adopts a combined structure of a connecting plate 611 and a vertical base plate 612, which can provide a stable support platform to ensure that the rotating winding assembly 6 does not shake or displace during operation, thereby improving the accuracy and stability of the winding. At the same time, the support seat 61 also needs to be easy to install and adjust to meet the winding requirements of hollow cup motor coils of different specifications. The fourth servo motor 62 can achieve precise speed and position control, thereby ensuring the rotation accuracy and stability of the triangular winding tooling 642 during the winding process. Its stable power output provides reliable power guarantee for the entire winding operation. In addition, the use of the servo motor can also achieve stepless adjustment of the winding speed to adapt to the production of hollow cup motor coils of different specifications and requirements.

[0065] Specifically, see Figure 13 、 14 As shown, the rotating winding assembly 6 also includes a wire guide component 65 and a pressure wheel component 66, wherein the wire guide component 65 includes a mounting column 651 and a guide wire 652, the mounting column 651 is vertically installed in the four-corner tooling mounting seat 641, and the guide wire 652 is connected between the triangular winding tooling 642 and the mounting column 651, and is used to guide the copper wire 54 to reach the triangular winding tooling 642 for winding.

[0066] Through the guiding effect of the guide wire 652, the copper wire 54 can reach the winding position along a predetermined path, avoiding deviation or entanglement during the winding process, thereby improving the neatness and quality of the winding.

[0067] The combination of mounting post 651 and guide wire 652 applies a certain amount of tension to copper wire 54, ensuring that it remains appropriately taut during the winding process. This tension control helps improve the tightness and consistency of the coil, and avoids winding quality issues caused by loose copper wire 54.

[0068] In addition, the structure of the wire guide component 65 in this embodiment is relatively simple and easy to install and maintain. This design not only reduces manufacturing costs, but also reduces the complexity of the equipment and improves the reliability and maintainability of the system.

[0069] The pressure wheel component 66 includes a pressure mounting plate 661, a pressure wheel guide seat 662, two guide rods 663, a rotating shaft 664, a pressure wheel 665 and an elastic member 666. The pressure mounting plate 661 is connected to the four-corner tooling mounting seats 641, and the pressure wheel guide seat 662 is vertically connected to the pressure mounting plate 661. The setting of the pressure mounting plate 661 and the pressure wheel guide seat 662 provides a stable installation foundation to ensure that the pressure wheel 665 will not shake or displace during operation.

[0070] Two guide rods 663 are horizontally connected to either side of the pinch roller guide seat 662. A rotating shaft 664 is vertically mounted between the two guide rods 663. A pinch roller 665 is mounted on the rotating shaft 664 and can rotate with the movement of the copper wire 54. This rotational flexibility reduces friction between the copper wire 54 and the pinch roller 665, reducing wear on the copper wire 54 and extending the service life of the copper wire 54 and the pinch roller 665. An elastic member 666 is sleeved onto the guide rods 663, and the pinch roller 665 is adapted to press against the side of the triangular winding fixture 642.

[0071] Thus, the pressure wheel 665 is pressed against the side surface of the triangular winding tool 642 by the elastic member 666, ensuring that the copper wire 54 fits tightly to the winding tool during the winding process.

[0072] The clamping wheel 665 is used to apply uniform pressure to the copper wire 54, ensuring that the copper wire 54 is tightly attached to the surface of the triangular winding tool 642 during the winding process. This clamping action helps improve the tightness and consistency of the coil, preventing the copper wire 54 from loosening or gapping during the winding process, thereby improving the winding quality.

[0073] The setting of the elastic member 666 provides an elastic support force for the clamping wheel 665, so that it can be properly adjusted according to the tension of the copper wire 54 and the shape of the winding tooling. This elastic adjustment function can adapt to copper wires 54 of different specifications and diameters, enhancing the versatility and adaptability of the device.

[0074] It is understood that the design of the wire guide component 65 must ensure that the copper wire 54 follows an accurate and stable path as it enters the winding component 64. This guiding function prevents the copper wire 54 from drifting or tangling during the winding process, thereby improving the neatness and quality of the winding. Furthermore, the wire guide component 65 should also be adjustable to accommodate copper wires 54 of varying specifications and winding requirements.

[0075] Thus, the wire guide component 65 is responsible for accurately guiding the copper wire 54 onto the triangular winding fixture 642, while the pressure wheel component 66 ensures that the copper wire 54 fits tightly against the winding fixture during the winding process. This combination of guidance and pressure can effectively improve the neatness and quality of the winding, and avoid problems such as deviation, looseness, or gaps in the copper wire 54 during the winding process. The elastic adjustment function of the pressure wheel component 66 and the tension control function of the wire guide component 65 enable the entire device to dynamically adjust according to the tension of the copper wire 54 and the shape of the winding fixture. This dynamic adjustment capability enhances the adaptability and flexibility of the device and can meet the production needs of hollow cup motor coils of different specifications and models.

[0076] The wire guide component 65 and the pressure wheel component 66 together constitute an important part of the rotary winding assembly 6 , and work together with other components such as the winding component 64 to achieve precise winding of the copper wire 54 .

[0077] An embodiment of the present invention further provides a winding method using a fully automatic winding device for a coreless motor coil, the winding method comprising the steps of: Step S 100 : The driving cylinder 31 of the mandrel adjustment assembly 3 contracts, pushing the threading tube 341 of the threading mandrel component 34 to slide inside the rotating main shaft 23 by moving the baffle 342, so that the winding mandrel tooling 36 extends to the outside of the die head 44, and the sliding platform 1 moves to control the distance between the end face of the winding mandrel tooling 36 and the tooling surface of the triangular winding tooling 642 of the rotating winding assembly 6; Step S 200 : The third servo motor 41 of the die drive assembly 4 is controlled to remain stationary, and the first drive assembly 22 of the flying fork motion assembly 2 drives the first flying fork 24 to rotate, so that the copper wire 54 on the copper wire guide assembly 5 is wound around the winding mandrel tooling 36 and formed between the end surface of the winding mandrel tooling 36 and the tooling surface of the triangular winding tooling 642; Step S 300 : The driving cylinder 31 of the mandrel adjustment assembly 3 extends, and drives the threading tube 341 of the threading mandrel component 34 to retreat within the rotating spindle 23 through the movable baffle 342, so that the winding mandrel tooling 36 is retracted into the interior of the die head 44 by the first spring 361, and the sliding platform 1 is controlled to move backward; Step S 400 : Control the triangular winding tooling 642 in the rotating winding assembly 6 to rotate 90° to change the working surface. The coil on the original working surface is first pressed onto the original working surface by the clamping wheel 665 on the clamping wheel component 66. When it rotates 90° again, the coil passing through the clamping wheel 665 is peeled off by the guide wire 652 in the wire guide component 65 and falls onto the conveyor line of the conveyor belt component 67 for discharge.

[0078] In this step, the coil is removed from the triangular winding tooling 642 by the clamping wheel 665, and the coil is unloaded by the guide wire 652. Cutting operations can be performed between multiple groups of coils as needed. At the same time, the other unworked surface of the triangular winding tooling 642 can also be cleaned, sprayed with a release agent, etc.

[0079] By combining the rotating winding assembly 6 with the flying fork winding method, the coil can be continuously wound, which solves the technical problem of the existing hollow cup motor requiring continuous winding when winding multiple sets of coils. Compared with the existing manual winding operation method, it can not only ensure the quality and consistency of the coil, but also significantly improve efficiency.

[0080] In addition, the structural design of the rotating winding assembly 6 makes the connecting wire between two adjacent groups of coils shorter, meeting the requirements of multiple groups of continuous micro hollow cup motor coils and the intermediate connecting wire cannot be too long.

[0081] By combining the flying fork winding and the flat winding method, the flying fork winding method utilizes the synchronous movement of the first side sprocket transmission structure 432 and the second side sprocket transmission structure 433 to realize the situation that the first flying fork 24 on the rotating main shaft 23 rotates while the die head 44 does not rotate; at the same time, the first side sprocket transmission structure 432 and the second side sprocket transmission structure 433 are used to synchronously control the first flying fork 24 on the rotating main shaft 23 not to rotate, and the added third servo motor 41 drives the second main shaft drive pulley 4321 in the first side sprocket transmission structure 432 to a state where only the die head 44 rotates, and at the same time, the threading tube 341 in the core shaft adjustment assembly 3 is used to push the round head ejection piece 35 to move, thereby pressing the winding core shaft tooling 36, to avoid the situation where the rotation of the die head 44 drives the threading tube 341 in the core shaft adjustment assembly 3 to rotate.

[0082] This winding method can achieve continuous winding without wire breakage, and the connecting wires between each set of coils are relatively short, meeting the requirements of fully automated winding of small hollow cup motor coils.

[0083] Although the present invention is disclosed as above, the scope of protection disclosed by the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the scope of protection of the present invention.
