Description

Technical Field

[0001] This utility model relates to the field of external rotor winding technology, specifically a four-station flying fork type external rotor winding device. Background Technology

[0002] An external rotor motor is a type of motor characterized by an external rotor and an internal stator. It features a large rotor diameter and high moment of inertia, making it suitable for low-speed, high-torque applications. Because the rotor directly drives the load (such as an impeller or mechanical component), no additional transmission device is required, making it widely used in compressors, machine tools, electric vehicles, wind power generation, and household appliances (such as fans and air purifiers).

[0003] In the production process of motor outer rotors, winding is one of the core processes, and its level of automation directly affects production efficiency and product quality. In traditional outer rotor winding operations, manual assistance or single-station semi-automatic equipment is often used. Due to the cumbersome manual wire feeding, threading, and winding operations, not only is the labor intensity high, but human factors can also lead to insufficient winding accuracy and uneven coil arrangement, affecting the stability of product performance. Moreover, single-station equipment can only process one outer rotor at a time, resulting in a long production cycle and difficulty in meeting the needs of large-scale production. Therefore, we propose a four-station flying fork type outer rotor winding equipment. Utility Model Content

[0014] 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 protection scope of the present utility model.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a four-station flying fork type external rotor winding device, including a device body 1, four sets of wire feeding mechanisms 2 are installed on the top front side of the device body 1, a mounting plate 3 is slidably installed on the top middle of the device body 1, a push-pull cylinder 8 is fixedly installed on the top of the device body 1, the output shaft end of the push-pull cylinder 8 is fixedly connected to the front side of the mounting plate 3, four sets of rotating tubes 10 are rotatably inserted on the mounting plate 3, a first drive assembly is installed on the front side of the mounting plate 3, and a winding assembly is installed on the rear side of each of the four sets of rotating tubes 10. Four sets of winding assemblies are rotatably installed on the top rear side of the device body 1. The rotating column 20 has an outer rotor 9 inserted into the top of each of the four rotating columns 20. The second drive assembly is installed on the top side inside the equipment body 1. A gantry frame 5 is also fixedly installed on the top rear side of the equipment body 1. A lifting plate 6 is slidably installed on the gantry frame 5. A lifting cylinder 7 is fixedly installed on the top side of the gantry frame 5. The output shaft end of the lifting cylinder 7 is fixedly connected to the top side of the lifting plate 6. Four sets of positioning columns 16 are installed on the bottom side of the gantry frame 5. The bottom end of the positioning column 16 is inserted into the outer rotor 9. Four sets of wire clamping mechanisms 17 are also installed on the bottom side of the gantry frame 5. A positioning assembly is also installed on the top rear side of the equipment body 1.

[0016] When the four-station flying fork type external rotor winding equipment is in operation, four sets of wire feeding mechanisms 2 provide the wire required for winding. The wire passes through four sets of rotating tubes 10 on the mounting plate 3. The push-pull cylinder 8 drives the mounting plate 3 to slide, adjusting the position of the rotating tubes 10 and the rear winding assembly so that they correspond to the external rotor 9 inserted on the rear rotating column 20 at the top of the equipment body 1. The lifting cylinder 7 on the gantry 5 drives the lifting plate 6 to descend, causing the positioning column 16 to be inserted into the external rotor 9 for positioning. At the same time, the wire clamping mechanism 17 cooperates to fix the end of the wire. The first drive component drives the four sets of rotating tubes 10 to rotate, causing the winding assembly to move, so that the wire is wound on the external rotor 9. The second drive component drives the rotating column 20 to rotate, cooperating with the winding assembly to complete the winding operation. The positioning component assists in fixing the external rotor 9 to ensure the stability of the winding process.

[0017] The first drive assembly includes a drive motor 4, which is fixedly mounted on the front side of the mounting plate 3. A synchronous pulley 13 is fixedly sleeved on the output shaft end of the drive motor 4. A synchronous pulley 11 is fixedly sleeved on the front end of the two sets of rotating tubes 10 located in the middle. A synchronous pulley 12 is fixedly sleeved on the front end of the two sets of rotating tubes 10 located on the left and right sides. A synchronous belt 15 is tensioned and sleeved between the synchronous pulley 13 and the two sets of synchronous pulleys 11. A synchronous belt 14 is also tensioned and sleeved between the synchronous pulleys 11 and 12.

[0018] When the first drive assembly is working, after the drive motor 4 starts, the synchronous pulley 13 at the output shaft end rotates accordingly. Through the tensioned synchronous belt 15, it drives the synchronous pulley 11 at the front end of the two middle sets of rotating tubes 10 to rotate, thereby causing the two middle sets of rotating tubes 10 to rotate. At the same time, the synchronous pulley 11 on the middle rotating tube 10 drives the synchronous pulley 12 at the front end of the left and right rotating tubes 10 to rotate through the tensioned synchronous belt 14, realizing the synchronous rotation of the four sets of rotating tubes 10 and providing power for the operation of the subsequent winding assembly.

[0019] The winding assembly includes a rotating arm 27, which is fixedly sleeved on the rear side of the rotating tube 10. A winding arm 33 is fixedly connected to the top of the rotating arm 27, and a wire tube 34 is fixedly connected to the rear end of the winding arm 33. Synchronous pulleys 28 are rotatably mounted at both the front and rear ends of the bottom of the rotating arm 27. Four sets of synchronous pulleys 29 are fixedly mounted on the rear side of the mounting plate 3. A synchronous belt 31 is tensioned and sleeved between one set of synchronous pulleys 28 and 29. A wire laying mechanism 35 is rotatably sleeved at the rear end of the rotating tube 10. A synchronous pulley 30 is fixedly mounted on the front side of the wire laying mechanism 35. A synchronous belt 32 is tensioned and sleeved between another set of synchronous pulleys 28 and 30.

[0020] When the winding assembly is working, as the rotating tube 10 rotates, the rotating arm 27 fixedly sleeved behind it rotates synchronously, driving the winding arm 33 at the top and the conductor tube 34 at the rear to rotate. The synchronous pulleys 7 28 at the front and rear ends of the bottom of the rotating arm 27 rotate with the rotating arm 27. One set of synchronous pulleys 7 28 generates transmission through the synchronous belt 5 31 tensioned between the synchronous pulley 8 29 on the rear side of the mounting plate 3. The other set of synchronous pulleys 7 28 generates transmission through the synchronous belt 6 32 and the synchronous pulley 9 30. The transmission ratio between synchronous pulleys 7 28 and synchronous pulley 8 29 is the same as the transmission ratio between synchronous pulleys 7 28 and synchronous pulley 9 30. Since synchronous pulley 8 29 is fixed, synchronous pulley 9 30 is also fixed, thus keeping the wire laying mechanism 35 vertical. Through the coordinated action of the rotation of the winding arm 33 and the wire laying mechanism 35, the orderly winding of the wire is completed in conjunction with the conductor tube 34.

[0021] The second drive assembly includes a second drive motor 24, which is fixedly installed on the top side inside the equipment body 1. A sixth synchronous pulley 23 is fixedly sleeved on the output shaft end of the second drive motor 24. The bottom ends of the two sets of rotating columns 20 located in the middle are fixedly sleeved with fourth synchronous pulleys 21. The bottom ends of the two sets of rotating columns 20 located on the left and right sides are fixedly sleeved with fifth synchronous pulleys 22. A fourth synchronous belt 26 is tensioned and sleeved between the sixth synchronous pulley 23 and the two sets of fourth synchronous pulleys 21. A third synchronous belt 25 is also tensioned and sleeved between the fourth synchronous pulley 21 and the fifth synchronous pulley 22.

[0022] When the second drive assembly is working, after the drive motor 24 starts, the synchronous pulley 6 23 at the output shaft end rotates, which drives the synchronous pulley 4 21 at the bottom of the two middle sets of rotating columns 20 to rotate through the tensioned synchronous belt 4 26, causing the two middle sets of rotating columns 20 to rotate. At the same time, the synchronous pulley 4 21 on the middle rotating column 20 drives the synchronous pulley 5 22 at the bottom of the left and right rotating columns 20 to rotate through the tensioned synchronous belt 3 25, realizing the synchronous rotation of the four sets of rotating columns 20, providing rotational power for the outer rotor 9 inserted on it, and cooperating with the winding assembly to complete the winding operation.

[0023] The positioning assembly includes a sliding plate 18, which is slidably mounted on the top rear side of the equipment body 1. A push-pull cylinder 19 is fixedly mounted on the top of the equipment body 1. The output shaft end of the push-pull cylinder 19 is fixedly connected to the front side of the sliding plate 18. Two sets of positioning plates 36 are symmetrically arranged on the front side of each of the four sets of outer rotors 9. All eight sets of positioning plates 36 are fixedly mounted on the top side of the sliding plate 18. A clamping mechanism is provided on the rear side of each of the four sets of outer rotors 9.

[0024] The clamping mechanism includes a push-pull cylinder 37, which is fixedly installed on the top side of the equipment body 1. A clamping plate 38 is slidably installed on the top side of the push-pull cylinder 37. The output shaft end of the push-pull cylinder 37 is fixedly connected to the bottom side of the clamping plate 38. The front side of the clamping plate 38 abuts against the rear side of the outer rotor 9.

[0025] When the positioning component is working, the second push-pull cylinder 19 drives the sliding plate 18 to slide on the rear side of the top of the equipment body 1, which drives the eight sets of positioning plates 36 on the top side of the sliding plate 18 to move synchronously, so that the two sets of positioning plates 36 symmetrically arranged on the front side of the four sets of outer rotors 9 respectively abut against the front side of the outer rotors 9, realizing the positioning of the front side of the outer rotors 9. At the same time, the third push-pull cylinder 37 drives the clamping plate 38 on its top side to slide, so that the front side of the clamping plate 38 abuts against the rear side of the outer rotors 9, and works with the positioning plates 36 to clamp and fix the outer rotors 9 from the front and rear sides, ensuring that the position of the outer rotors 9 is stable during the winding process.

[0026] Working principle: During operation, the four-station flying fork type external rotor winding equipment provides the wire required for winding through four sets of wire feeding mechanisms 2. The wire passes through four sets of rotating tubes 10 on the mounting plate 3. The push-pull cylinder 8 drives the mounting plate 3 to slide, adjusting the position of the rotating tubes 10 so that they correspond to the external rotor 9 inserted into the rotating column 20 on the rear top of the equipment body 1. The lifting cylinder 7 on the gantry 5 drives the lifting plate 6 to descend, causing the positioning column 16 to be inserted into the external rotor 9 for positioning. At the same time, the wire clamping mechanism 17 cooperates to fix the end of the wire and pushes... The second cylinder 19 drives the sliding plate 18 to slide on the rear side of the top of the equipment body 1, which drives the eight sets of positioning plates 36 on the top side of the sliding plate 18 to move synchronously, so that the two sets of positioning plates 36 symmetrically arranged on the front side of the four sets of outer rotors 9 respectively abut against the front side of the outer rotors 9, realizing the positioning of the front side of the outer rotors 9. At the same time, the third cylinder 37 drives the clamping plate 38 on its top side to slide, so that the front side of the clamping plate 38 abuts against the rear side of the outer rotors 9, and works with the positioning plates 36 to clamp and fix the outer rotors 9 from the front and rear sides, ensuring that the outer rotors 9 are stable in position during the winding process. Next, the drive motor 4 is started, and the synchronous pulley 13 at the output shaft end rotates accordingly. Through the tensioned synchronous belt 15, it drives the synchronous pulleys 11 at the front ends of the two middle sets of rotating tubes 10 to rotate, thus causing the two middle sets of rotating tubes 10 to rotate. Simultaneously, the synchronous pulleys 11 on the middle rotating tube 10, through the tensioned synchronous belt 14, drive the synchronous pulleys 12 at the front ends of the left and right rotating tubes 10 to rotate, achieving synchronous rotation of the four sets of rotating tubes 10. When the rotating tubes 10 rotate, the rotating arm 27, fixedly sleeved behind them, rotates synchronously, driving the top winding arm 33 and the rear conductor tube 34 to rotate. The synchronous pulleys 28 at the front and rear ends of the bottom of the rotating arm 27 also rotate synchronously. The rotating arm 27 rotates, and one set of synchronous pulleys 7 28 generates transmission through the synchronous belt 5 31 tensioned between synchronous pulley 8 29 on the rear side of the mounting plate 3. The other set of synchronous pulleys 7 28 generates transmission through synchronous belt 6 32 and synchronous pulley 9 30. The transmission ratio between synchronous pulleys 7 28 and synchronous pulley 8 29 is the same as the transmission ratio between synchronous pulleys 7 28 and synchronous pulley 9 30. Since synchronous pulley 8 29 is fixed, synchronous pulley 9 30 is also fixed, which in turn keeps the wire laying mechanism 35 vertical. Through the rotation of the winding arm 33 and the coordinated action of the wire laying mechanism 35, the wire is wound in an orderly manner with the guide tube 34, so that the wire is wound on the outer rotor 9. After the outer rotor 9 is wound once, the drive motor 24 is started. The synchronous pulley 23 at the output shaft end rotates, which drives the synchronous pulleys 21 at the bottom of the two middle sets of rotating columns 20 to rotate through the tensioned synchronous belt 26. At the same time, the synchronous pulleys 21 on the middle rotating column 20 drive the synchronous pulleys 22 at the bottom of the left and right rotating columns 20 to rotate through the tensioned synchronous belt 25. This achieves synchronous rotation of the four sets of rotating columns 20, providing rotational power for the outer rotor 9 inserted on them, and completing the winding operation of the outer rotor 9 in conjunction with the winding assembly.
