[0015] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application (for the convenience of description and understanding, the following is Figure 2 All other embodiments obtained by persons of ordinary skill in the art without creative work shall fall within the scope of protection of this application.

[0016] See also Figure 1-4 The present application provides a technical solution: a winding device for a transformer, comprising a workbench 7, a step of the workbench 7 being provided with a winding group, the winding group comprising a coil winding and a tightening portion, the coil winding and the tightening portion being arranged opposite to each other.

[0017] The workbench 7 serves as the base of the entire system, supporting and positioning all mechanical components. The winding assembly, consisting of a coil winding unit and a tensioning unit, is used to tightly wind the wire into the desired shape and size. These two components work together to achieve high-quality winding. The coil winding unit handles the actual winding process, while the tensioning unit applies pressure to ensure a tight, secure winding.

[0018] The coil winding includes a winding motor 8 and a mounting connection frame 9. The output end of the winding motor 8 is provided with a mounting connection frame 9. The tightening part includes a support seat 10, a tightening shaft 2 and a driving cylinder 1. The driving cylinder 1 is provided on the support seat 10. The telescopic end of the driving cylinder 1 is connected to the tightening shaft 2.

[0019] When the winding motor 8 is started, it generates a rotational motion for winding the wire to form a coil. The mounting connecting frame 9 is used to connect the output power of the winding motor 8 to the winding actuator. The coil is placed on the actuator, and the other end of the actuator is connected to the mounting connecting frame 9, which serves as a bridge between the winding motor 8 and the wound wire, ensuring that the rotational motion of the winding motor 8 can be accurately converted into the formation of the coil.

[0020] The support base 10 provides a stable installation base for the tightening part, ensuring that the tightening part can be firmly fixed on the workbench during operation and will not be displaced due to external force or vibration.

[0021] The driving cylinder 1 is used to control the movement of the tightening shaft 2, thereby adjusting the tightening force to ensure that the actuator is neither too loose nor too tight during the winding process and maintains appropriate tension.

[0022] The tensioning shaft 2 adjusts the distance from the actuator by driving the expansion and contraction of the cylinder 1. During the winding process, the tensioning shaft 2 will apply a certain amount of pressure as needed to fit tightly with the actuator to avoid loosening or deformation during subsequent use.

[0023] The workbench 7 is also provided with a pay-off group and a moving group. The pay-off group is located on the moving group. The pay-off group includes a winding mounting frame 11, a pay-off wheel 13, an auxiliary wheel 12 and a clamping guide wheel 18. The winding mounting frame 11 is E-shaped, the auxiliary wheel 12 is located on both sides of the winding mounting frame 11, and the pay-off wheel 13 is located in the middle position of the winding mounting frame 11.

[0024] The winding mounting frame 11 supports and guides the operation of the pay-off wheel 13 and the auxiliary wheel 12. The winding mounting frame 11 ensures stability and guidance during the pay-off process, so that the wire can be smoothly led out of the pay-off wheel and enter the winding area.

[0025] Pay-off wheel 13 is used for storing the wire to be wound. Along with the carrying out of the winding process, pay-off wheel 13 can release the wire gradually, guarantees the continuous supply of wire.

[0026] The auxiliary wheel 12 is located on one side of the winding mounting frame 11 to assist in guiding the wire, reduce friction and swinging of the wire during the pay-off process, and ensure that the wire enters the winding area smoothly.

[0027] The compression guide wheel 18 is used to perform the final guidance and compression before the wire enters the winding area, ensuring that the wire maintains the correct path and tension during the winding process, and avoiding unnecessary twisting or damage during the winding process.

[0028] Furthermore, the clamping guide wheel 18 is provided with a corresponding clamping group, which includes a rotating adjustment shaft 15, a mounting connecting plate 16 and a guide sleeve 19. The guide sleeve 19 is socketed with the end shaft on the clamping guide wheel 18. The 15 is located on one side of the upper surface of the winding mounting frame 11, and the mounting connecting plate 16 is threadedly connected to the screw hole of 15 and one end of it is connected to the upper surface of the guide sleeve 19.

[0029] When the winding device is in operation, the compression guide wheel 18 contacts the wire, guiding it along the predetermined path and applying appropriate tension to ensure that the wire does not sag or shift during the winding process. If the position of the compression guide wheel 18 needs to be adjusted, fine-tuning can be performed by rotating the adjustment shaft 15. The rotation of the adjustment shaft 15 is transmitted to the guide sleeve 19 through the mounting plate 16, thereby changing the height of the compression guide wheel 18 to accommodate different wire materials or winding requirements.

[0030] Furthermore, a strip groove for adjusting the upward and downward movement of the pressing guide wheel 18 is provided on the winding mounting frame 11 where the pressing guide wheel 18 is installed.

[0031] Furthermore, a sliding guide block 14 is provided below the winding mounting frame 11 , and the sliding guide block 14 is slidably provided on the sliding guide seat 4 of the moving group.

[0032] Furthermore, the moving group includes a screw motor 3, a sliding guide seat 4, a screw 5 and a mounting seat 6. The mounting seat 6 is located at one end of the sliding guide seat 4. One end of the screw 5 is sleeved in the mounting seat 6, and the other end is connected to the output end of the screw motor 3. The screw slide sleeved on the screw 5 is connected to the winding mounting frame 11 in the pay-off group.

[0033] When the position of the pay-off assembly needs to be adjusted, the screw motor 3 starts to rotate, driving the screw 5. Since one end of the screw is fixed in the mounting seat 6, the rotation of the screw 5 causes the screw slide to move linearly along the screw 5, and the movement of the screw slide drives the winding mounting frame 11 connected to it to move along the sliding guide seat 4, thereby achieving precise positioning and movement of the pay-off assembly during the entire winding process.

[0034] It ensures that the wire can be wound according to the preset path and speed, improves the winding accuracy and efficiency, and also facilitates the processing of coil winding tasks of different sizes and shapes. Through the precise control of the screw motor 3, complex or variable winding modes can be achieved to meet a wider range of application needs.

[0035] During use: turn on the power and start the winding motor 8. At this time, the winding motor 8 generates a rotational motion, and transmits the power to the winding actuator through the mounting connection frame 9 to start the winding process. According to the specifications of the wound coil, adjust the driving cylinder 1, control the extension and contraction of the tightening shaft 2, and apply appropriate tightening force to the actuator mechanism located on the mounting connection frame 9 to ensure that the coil is neither too loose nor too tight during the winding process. The wire to be wound is rolled onto the pay-off wheel 13, and the pay-off wheel 13 starts to release the wire according to the winding speed to ensure the continuous supply of the wire. The wire is guided by the auxiliary wheel 12 to reduce the friction and swing of the wire during the pay-off process, ensuring that the wire enters smoothly. In the winding area, during the winding process, the compression guide wheel 18 contacts the wire material for the final guidance and compression, ensuring that the wire material maintains the correct path and tension during the winding process. If the position of the compression guide wheel 18 needs to be adjusted, it can be fine-tuned by rotating the adjustment shaft 15. The rotation of the rotation adjustment shaft 15 is transmitted to the guide sleeve 19 through the installation connecting plate 16, changing the height of the compression guide wheel 18 to adapt to different wire materials or winding requirements. According to the needs of winding, the screw motor 3 starts to rotate, driving the screw 5 to rotate. The screw slide moves linearly with the rotation of the screw 5, driving the winding mounting frame 11 to move along the sliding guide seat 4, realizing the precise positioning and movement of the pay-off group throughout the winding process. Thus, the winding of the coil is completed.

[0036] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
