[0027] Please refer to Figures 1-4, the present utility model provides a technical solution: an automatic wire arranging and winding machine for transformer production, including a base 1, an iron core extrusion assembly. The iron core extrusion assembly is arranged on the base 1. The iron core extrusion assembly includes a fixed seat 7. The fixed seat 7 is fixedly connected to the base 1. Two telescopic rods 8 are fixedly connected to the fixed seat 7. An activity plate 9 is arranged above the fixed seat 7. The activity plate 9 is fixedly connected to the output ends of the two telescopic rods 8. Two activity rods 10 are slidably connected inside the activity plate 9. An iron core support 11 is arranged above the activity plate 9. The two activity rods 10 are both fixedly connected to the iron core support 11. Springs 18 are sleeved on the surfaces of the two activity rods 10. The upper end of the iron core support 11 is arc-shaped.

[0028] A second driving motor 12 is fixedly connected to the left side of the base 1. The output end of the second driving motor 12 is fixedly connected to a bidirectional threaded rod 13. The bidirectional threaded rod 13 is rotatably connected to the base 1. Two activity brackets 14 are threadedly sleeved on the surface of the bidirectional threaded rod 13. Iron core fixing frames 16 are rotatably connected inside the two activity brackets 14. A third driving motor 15 is fixedly connected to the surface of the left activity bracket 14. The output end of the third driving motor 15 is fixedly connected to the corresponding iron core fixing frame 16. An iron core 17 is arranged on the opposite surfaces of the two iron core fixing frames 16.

[0029] A guide rail 2 is fixedly connected to the base 1. A first driving motor 6 is fixedly connected to the left side of the guide rail 2. The output end of the first driving motor 6 is fixedly connected to a threaded rod 3. The threaded rod 3 is rotatably connected to the guide rail 2. A moving block 4 is threadedly sleeved on the surface of the threaded rod 3. The moving block 4 is slidably connected to the guide rail 2. The upper end of the moving block 4 is rotatably connected to a wire guiding frame 5.

[0030] Two rollers 19 are rotatably connected inside the iron core support 11.

[0031] When using this device, first pass the wire through the wire guiding frame 5 and wind it around the iron core 17. Start the telescopic rod 8 to drive the movable plate 9 to rise. The movable plate 9 drives the movable rod 10 and the iron core support 11 to rise, so that the iron core support 11 contacts the iron core 17. Start the third drive motor 15 to drive the iron core fixing frame 16 and the iron core 17 to rotate, and wind the wire, which is convenient for the production of the iron core of the transformer. During the rotation of the iron core 17, the iron core support 11 will squeeze the iron core 17, so that the roller 19 contacts the iron core 17, causing the roller 19 to rotate, which is convenient for squeezing the wire on the surface of the iron core 17 during the rotation of the iron core 17, reducing the gap between the wires wound on the surface of the iron core 17, reducing the resistance during the rotation of the iron core 17, improving the overall tightness of the iron core 17, reducing eddy current and hysteresis losses, and improving the performance of the transformer. Since the diameter of the wire will continuously increase during the winding process, through the setting of the spring 18, it is convenient for the iron core 17 to generate a downward pressure on the iron core support 11, causing the iron core support 11 to move downward. The iron core support 11 squeezes the spring 18, which is convenient for fine-tuning the distance between the iron core support 11 and the iron core 17, preventing the iron core support 11 from detaching from the iron core 17 during the downward movement and affecting the production of the transformer core.

[0032] During the process of winding the wire, the wire is guided by the wire guiding frame 5. Start the first drive motor 6 to drive the threaded rod 3 to rotate. The threaded rod 3 drives the moving block 4 to slide inside the guide rail 2, which is convenient for guiding the wire to wind around the iron core 17. By the forward and reverse rotation of the first drive motor 6, it is convenient to drive the wire guiding frame 5 to move back and forth, facilitating the uniform multi-layer winding of the wire around the iron core 17, and at the same time preventing the wire from being twisted, folded or damaged during the winding process, ensuring the integrity and reliability of the wire, and extending the service life of the transformer.

[0033] When the wire winding is completed, start the second drive motor 12 to drive the bidirectional threaded rod 13 to rotate. The bidirectional threaded rod 13 drives the two movable brackets 14 to move away from each other. The two movable brackets 14 drive the corresponding third drive motor 15 and the iron core fixing frame 16 to move, which is convenient for the two iron core fixing frames 16 to separate from the iron core 17. At the same time, the iron core 17 is supported by the iron core support 11 to prevent the iron core 17 from directly falling off after the winding is completed, causing damage to the iron core 17, and facilitating the removal of the iron core 17.

[0034] Furthermore, the iron core 17 is squeezed by the iron core support 11 and the roller 19, which is convenient for reducing the gap between the wires wound on the surface of the iron core 17 during the wire winding process, reducing the resistance during the rotation of the iron core 17, improving the overall tightness of the iron core 17, reducing eddy current and hysteresis losses, enhancing the performance of the transformer. At the same time, by using the spring 18, it is convenient to generate a stable squeezing force on the iron core 17, continuously squeeze the iron core 17, improve the winding quality, enhance the practicality of the device, and improve the stability of the iron core 17 during winding.

[0035] Through the reciprocating movement of the wire guiding frame 5, it is convenient to guide the wire, facilitate the wire to be stably wound on the surface of the iron core 17, and at the same time prevent the wire from being twisted, folded or damaged during the winding process, ensuring the integrity and reliability of the wire and extending the service life of the transformer.

[0036] Working principle: When using this device, first pass the wire through the wire guiding frame 5 and wind it on the iron core 17. Start the telescopic rod 8 to drive the movable plate 9 to rise. The movable plate 9 drives the movable rod 10 and the iron core support 11 to rise, so that the iron core support 11 contacts the iron core 17. Start the third drive motor 15 to drive the iron core fixing frame 16 and the iron core 17 to rotate, and wind the wire, which is convenient for producing the iron core of the transformer. During the rotation of the iron core 17, the iron core support 11 will squeeze the iron core 17, making the roller 19 contact the iron core 17, causing the roller 19 to rotate, which is convenient for squeezing the wire on the surface of the iron core 17 during the rotation of the iron core 17, reducing the gap between the wires wound on the surface of the iron core 17, reducing the resistance during the rotation of the iron core 17, improving the overall tightness of the iron core 17, reducing eddy current and hysteresis losses, and enhancing the performance of the transformer. Since the diameter of the wire will continuously increase during the winding process, through the setting of the spring 18, it is convenient for the iron core 17 to generate a downward pressure on the iron core support 11, causing the iron core support 11 to move downward. The iron core support 11 squeezes the spring 18, which is convenient for fine-tuning the distance between the iron core support 11 and the iron core 17, preventing the iron core support 11 from detaching from the iron core 17 during the descent and affecting the production of the transformer core.

[0037] During the wire winding process, the wire is guided by the wire guiding frame 5. Start the first drive motor 6 to drive the threaded rod 3 to rotate. The threaded rod 3 drives the moving block 4 to slide inside the guide rail 2, which is convenient for guiding the wire to be wound on the iron core 17. By rotating the first drive motor 6 forward and backward, it is convenient to drive the wire guiding frame 5 to reciprocate, facilitating the wire to be evenly wound on the iron core 17 in multiple layers, and at the same time preventing the wire from being twisted, folded or damaged during the winding process, ensuring the integrity and reliability of the wire and extending the service life of the transformer.

[0038] After the wire winding is completed, start the second driving motor 12 to drive the bidirectional threaded rod 13 to rotate. The bidirectional threaded rod 13 drives the two movable brackets 14 to move away from each other. The two movable brackets 14 drive the corresponding third driving motors 15 and the iron core fixing brackets 16 to move, facilitating the separation of the two iron core fixing brackets 16 from the iron core 17. At the same time, the iron core 17 is supported by the iron core bracket 11 to prevent the iron core 17 from falling off directly after the winding is completed, causing damage to the iron core 17 due to its fall, and facilitating the removal of the iron core 17. The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
