[0029] Embodiment 1

[0030] Please refer to Figure 1, an embodiment of the present utility model provides a transformer coil winding mechanism, which includes a base 100, a winding mechanism 200 and a lead wire mechanism 300 arranged on the base 100. The winding mechanism 200 is responsible for winding the coil 211, and the lead wire mechanism 300 is responsible for introducing the coil 211, so that the coil 211 is available when the winding mechanism 200 winds the coil 211, rather than winding it in a messy manner. The winding mechanism 200 and the lead wire mechanism 300 are both arranged on a base 100, and the base 100 is a rectangular plate. The installation height of the lead wire mechanism 300 is lower than that of the winding mechanism 200, so that there is a height difference when the coil 211 enters the winding mechanism 200, and the coil 211 has a pressing force, so that the position of the coil 211 is more accurate when it is wound.

[0031] The base 100 serves as a stable support platform, providing a solid installation foundation for the winding mechanism 200 and the lead wire mechanism 300. The main function of the winding mechanism 200 is to wind the coil 211 to ensure the stability and neatness of the coil 211 during the manufacturing process. The lead wire mechanism 300 is responsible for guiding the coil 211 into the winding mechanism 200, so that when the winding mechanism 200 winds, the coil 211 can be kept neat and avoid messy situations. These two key mechanisms are both installed on the base 100, and the base 100 is designed as a rectangular plate, which not only ensures the stability of the mechanism but also facilitates installation and maintenance. In terms of design, the installation position of the lead wire mechanism 300 is lower than that of the winding mechanism 200, so that a height difference will be formed when the coil 211 enters the winding mechanism 200. The design of this height difference enables the coil 211 to receive a uniform pressing force when entering the winding mechanism 200, thus ensuring the position accuracy of the coil 211 during the winding process. Through this design, the coil 211 is not only neater but also more accurate in position during the winding process, greatly improving the winding efficiency and the quality of the coil 211.

[0032] Please refer to Figure 1 and Figure 2 , the winding mechanism 200 includes a coil carrier 210 and a driving motor 231; the coil carrier 210 is fixed on a rotating shaft 240; the driving motor 231 drives the rotating shaft 240 to rotate. The winding mechanism 200 is provided with a driving motor 231, and automatic winding can be realized through the driving motor 231. By controlling the rotation speed of the driving motor 231, the rotation speed of the rotating shaft 240 driving the coil carrier 210 can be controlled, and the winding speed of the coil 211 can also be controlled, so as to obtain an optimal winding speed for winding the coil 211.

[0033] Please refer to Figure 2, The winding mechanism 200 is characterized by being equipped with a driving motor 231, enabling the winding process to be automated. By precisely controlling the rotational speed of the driving motor 231, we can simultaneously control the rotational speeds of the rotating shaft 240 and the coil carrier 210, thereby adjusting the winding speed of the coil 211. Such a design allows us to obtain an ideal winding speed while ensuring the quality of the coil 211, greatly improving the efficiency and accuracy of the winding work. In addition, this control method also makes it simple and convenient to adjust the winding speed. The operator can easily adjust it according to needs to achieve the best winding effect. Through this winding mechanism 200, an automated winding process is achieved, and by controlling the rotational speed of the driving motor 231, the flexible adjustment of the winding speed is realized, improving the efficiency and quality of the winding work.

[0034] The lead wire mechanism 300 is provided with a first mounting plate 310; on both sides of the first mounting plate 310, there are respectively a first guide rail support plate 311 and a second guide rail support plate 312. The lead wire mechanism 300 is provided with the first mounting plate 310 to mount the first guide rail support plate 311 and the second guide rail support plate 312. The following lead wire components are supported by the first guide rail support plate 311 and the second guide rail support plate 312.

[0035] Please refer to Figure 1 and Figure 3 , on the first guide rail support plate 311 and the second guide rail support plate 312, there are a guide rail rod 321 and a driving lead screw 322. The guide rail rod 321 provides a fixed moving path, and the driving lead screw 322 provides a mutually driving component. On one side of the driving lead screw 322, there is a servo motor 330; the output shaft of the servo motor 330 is in transmission connection with the driving lead screw 322. The servo motor 330 is arranged outside the first guide rail 413 plate, that is, at one end of the driving lead screw 322. The output shaft of the servo motor 330 is in transmission connection with the driving lead screw 322. The servo motor 330 can drive the driving lead screw 322 to rotate. The driving lead screw 322 rotates based on the first guide rail support plate 311 and the second guide rail support plate 312. Threads are provided on the driving lead screw 322. A moving seat 340 is also provided between the first guide rail support plate 311 and the second guide rail support plate 312. The moving seat 340 is directly engaged with the driving lead screw 322, and the moving seat 340 moves along the path of the guide rail rod 321. When the driving lead screw 322 is driven, the driving lead screw 322 rotates, and the moving seat 340 moves in different directions along the guide rail rod 321 based on the thread helix direction of the driving lead screw 322.

[0036] Please refer to Figure 3, a lead block 350 is designed on the moving seat 340; the coil 211 passes through the lead block 350 and is wound around the coil carrier 210. The lead block 350 structurally serves to provide a winding conveying path for the wires on the coil 211. Specifically, the wires on the coil 211 pass through the preset holes on the lead block 350, then extend to the coil carrier 210, and then are wound by the rotational movement of the coil carrier 210. This design makes the winding process of the coil 211 smoother and improves the overall efficiency.

[0037] By precisely controlling the rotation speed and direction of the driving lead screw 322, the moving seat 340 moves smoothly and precisely along the predetermined path of the guide rail rod 321 in the direction approaching or moving away from the servo motor 330. Thanks to the parallel layout of the lead mechanism 300 and the winding mechanism 200, when the moving seat 340 performs a moving operation, it will synchronously drive the coil 211 to perform a corresponding movement. Therefore, the coil 211 can effectively cover both end portions of the coil carrier 210, realizing the complete winding of the coil 211 on the surface of the coil carrier 210. This process ensures the uniform distribution and tight fitting of the coil 211, improving the winding quality and efficiency.

[0038] Please refer to Figure 2 , the winding mechanism 200 is further provided with a first support plate 221 and a second support plate 222; there is a spacing distance between the first support plate 221 and the second support plate 222. This spacing facilitates the setting of the coil carrier 210, and this spacing distance is also the maximum width for setting the coil carrier 210. The coil carrier 210 is set on the rotating shaft 240 through this spacing distance and can be driven to rotate by the rotation of the rotating shaft 240.

[0039] The first support plate 221 and the second support plate 222 are designed and installed with a first bearing seat 223 and a second bearing seat 224. The design of these bearing seats is specifically for accommodating and fixing the rotating shaft 240, which is the core of the entire mechanical structure. The rotating shaft 240 is placed inside the first bearing seat 223 and the second bearing seat 224, ensuring that the rotating shaft 240 can rotate smoothly under the guidance and support of the two bearing seats. This design not only provides a basis for the rotation of the rotating shaft 240, ensuring the smoothness of rotation, but also greatly increases the rotational stability through the fixing effect of the bearing seats. In this way, it has great benefits for both the precision of the machine and the durability of long-term use.

[0040] One end of the rotating shaft 240 is provided with a driven wheel 241, which is firmly connected to the rotating shaft 240 to ensure that the rotating shaft 240 can rotate together with the driven wheel 241. Both ends of the rotating shaft 240 pass through the first bearing seat 223 and the second bearing seat 224 respectively, so that the rotating shaft 240 can rotate freely between the two bearing seats, thereby driving the driven wheel 241 to rotate. The first bearing seat 223 and the second bearing seat 224 can be rolling bearings to reduce the friction force when the rotating shaft 240 rotates and improve the rotation efficiency. In addition, a transmission gear can also be arranged on the rotating shaft 240 and meshed with the driven wheel 241 to achieve power transmission. In this way, the rotating shaft 240 device can effectively achieve power transmission and has the advantages of simple structure and high reliability.

[0041] Preferably, a third support plate 230 is provided on one side of the first support plate 221; the motor is arranged on the third support plate 230; a driving wheel 232 is provided on the output shaft of the driving motor 231; the driving wheel 232 is fixedly connected to the output shaft, and the driving wheel 232 is in meshing transmission with the driven wheel 241. The main function of the third support plate 230 is to increase the overall stability and install the driving motor 231 at the same time, making the operation of the driving motor 231 smoother; on the output shaft of the driving motor 231, a driving wheel 232 is provided. The driving wheel 232 and the output shaft are fixedly connected in this way, which can ensure that the driving wheel 232 can completely receive the power from the motor; in addition, the driving wheel 232 and the driven wheel 241 are connected by meshing transmission, which improves the transmission efficiency and makes the whole system run more smoothly.

[0042] Furthermore, please refer to Figure 3 , the moving seat 340 includes a receiving block 341 and a moving block 342; the moving block 342 passes through the driving lead screw 322 and the guide rod 321 at the same time. The moving seat 340 is mainly composed of two parts: the receiving block 341 and the moving block 342. These two parts cooperate closely to achieve precise moving operations. The main function of the receiving block 341 is to provide a solid platform for installing and fixing the lead block 350. This platform provides a stable foundation for the setting of the lead block 350, ensuring the stability and reliability of the lead block 350 during the moving process.

[0043] The moving block 342 plays a more crucial role. It not only drives the movement of the entire moving seat 340 but also is arranged to pass through the driving lead screw 322 and the guide rail rod 321. This design utilizes the interaction between the driving lead screw 322 and the guide rail rod 321, enabling the moving block 342 to move along a specific path on the guide rail rod 321. This design not only improves the moving accuracy of the moving seat 340 but also increases its flexibility and adaptability. The movement of the entire moving seat 340 is driven by the moving block 342, which can move smoothly on the guide rail rod 321, thereby driving the entire moving seat 340 to make precise position adjustments.

[0044] Embodiment 2

[0045] Please refer to Figure 4 , the embodiment of the present utility model provides a transformer coil winding mechanism. Different from Embodiment 1, a tensioning mechanism 400 is provided on the basis of Embodiment 1 in this embodiment. When the coil 211 is wound, if the coil 211 is loose, the winding quality of the coil 211 will be poor during winding and cannot meet the usage standards. Therefore, a tensioning force needs to be applied to the coil 211 so that the coil 211 will not bend or have poor winding quality during winding.

[0046] The tensioning mechanism 400 includes a second mounting plate 410, and a first pulley 411, a second pulley 412, and a tensioning wheel 415 are provided on the second mounting plate 410. The positions of the first pulley 411, the second pulley 412, and the tensioning wheel 415 are arranged in an isosceles triangle. This ensures the stability of the structure and also makes the cooperation between the pulleys smoother. The first pulley 411 and the second pulley 412 are arranged at the same height. A guide rail 413 and a slider 414 cooperating with the guide rail 413 are provided on the second mounting plate 410; the tensioning wheel 415 is arranged on the slider 414. The tensioning mechanism 400 adjusts the distance between the tensioning wheel 415 and the first pulley 411 and the second pulley 412 by adjusting the position of the slider 414 to achieve the adjustment of the tension degree of the coil 211.

[0047] Furthermore, the first pulley 411 and the second pulley 412 are arranged at the same height on the second mounting plate 410. Such a design can effectively reduce the unnecessary friction that may be generated due to different heights, thereby improving the operating efficiency of the entire mechanism.

[0048] On the second mounting plate 410, a guide rail 413 is further provided. The function of the guide rail 413 is to guide the movement of the slider 414. The slider 414 is a component that closely cooperates with the guide rail 413, and its movement is controlled by the tensioning mechanism 400. The tensioning pulley 415 is mounted on the slider 414, and its function is to adjust the tension of the coil 211 by cooperating with the first pulley 411 and the second pulley 412.

[0049] The working principle of the tensioning mechanism 400 is to change the distance between the tensioning pulley 415 and the first pulley 411 and the second pulley 412 by adjusting the position of the slider 414, so as to achieve precise adjustment of the tension of the coil 211. The coil 211 sequentially passes through the first pulley 411, the tensioning pulley 415 and the second pulley and then enters the lead block 350. During winding, the coil carrier 210 rotates, and the coil 211 is wound in a cycle from one end to the other end of the coil carrier 210. At this time, the moving seat 340 of the lead mechanism 300 moves according to the drive of the servo motor 330, and moves in a cycle from one end to the other end of the coil carrier 210. By adapting the rotation direction and speed of the servo motor 330 to the rotation speed of the coil carrier 210 and the winding direction of the coil 211, the winding of the coil 211 is completed through the cyclic operation of the winding mechanism 200 and the lead mechanism 300. When winding the coil 211, the coil carrier 210 can be provided on the rotating shaft 240, or it can be replaced by other carriers of the transformer for winding the coil 211.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
