Preferred embodiments of the present invention are shown in the drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive disclosure of the present invention.

[0023] It should be noted here that, for the sake of ease of illustration and description, only a portion of the base 10 of this embodiment is shown. According to structural requirements, each bracket of the base 10 has a pair, and brackets are provided on both sides of the supported component. This is easy for those skilled in the art to understand, so this embodiment will not go into details.

[0024] The driving part 20 includes a driving bevel gear 21, a transmission screw 22, a pressing part 23, an output rod 24 and a belt 25. The driving bevel gear 21 is hinged on the input bracket 11. The driving bevel gear 21 is connected to the power source. The power source provides rotational power for the driving bevel gear 21. The transmission screw 22 is hinged in the hinge hole on the lower side of the main bracket 12. A driven bevel gear 221 is installed on the transmission screw 22. The driven bevel gear 221 is meshed with the driving bevel gear 21 for transmission. The end of the driving screw 22 has an external output pulley 22, which outputs the rotation of the driving screw 22 to the winding part 30. The part of the driving screw 22 located outside the driven bevel gear 221 is a threaded area, and the threaded area is screwed with a clamping part 23. The part of the driving screw 22 located between the driven bevel gear 221 and the external output pulley 22 is a polished rod area. The clamping part 23 includes a threaded seat 231, a spiral ear piece 232, a telescopic rod 233 and a pressure head 234. The threaded seat 231 The threaded area of the transmission rod 22 is screwed together, and a spiral ear piece 232 is provided above the threaded seat 231. The spiral ear piece 232 is connected to the output rod 24. The side of the threaded seat 231 is provided with a telescopic rod 233. The end of the telescopic rod 233 is connected to the pressure head 234. The pressure head 234 presses the iron core 32 of the winding part 30 to press the wound wire onto the iron core 23. The telescopic rod 233 is a spring telescopic rod, which automatically adjusts the pressing degree of the pressure head 234 according to the winding degree of the iron core 32. The output rod 24 is hinged in the upper hinge hole of the main bracket 12. The output rod 24 has a screw 241, which cooperates with the screw ear 232 for transmission. The inner side of the spiral ear 232 has a spiral groove that matches the screw 241. The end of the output rod 24 has an internal output pulley 242, which outputs the rotational motion to the guide part 40. The belt 25 is installed between the internal output pulley 242 and the pulley at the end of the follower screw 43 of the guide part 40 to achieve transmission. It should be noted that the belt 25 needs to be installed across the rotating shaft 31 of the winding part 30. At this time, it is necessary to pay attention to the installation order of the belt 25 and the installation position of the rotating shaft 31 to avoid interference. Those skilled in the art will easily understand this and will not be elaborated here.

[0025] The winding portion 30 includes a rotating shaft 31, an iron core 32, and an external driven pulley 33. The rotating shaft 31 is hinged to the winding bracket 14. The end of the rotating shaft 31 has an external driven pulley 33. The external driven pulley 33 and the external output pulley 222 are driven by a belt (not shown in the figure). The iron core 32 is installed on the rotating shaft 31. In this embodiment, a wire is wound around the iron core 32 to form a coil. It should be noted that the installation of the iron core 32 on the rotating shaft 31 needs to be designed according to actual needs. For the sake of ease of illustration and description, this embodiment adopts a simplified schematic method. Because the installation of the iron core 32 on the rotating shaft 31 is not the main content of this embodiment, those skilled in the art can install the iron core 32 on the rotating shaft 31 according to conventional methods in the field.

[0026] The guide portion 40 includes a guide bracket 41, a joint 42 and a follower screw 43. The guide bracket 41 is sleeved on the joint 42. The overall structure of the follower screw 43 is consistent with the overall structure of the output rod 24. It also has a pulley and a spiral. The joint 42 and the follower screw 43 are connected by a spiral fit. Each side of the joint 42 has an ear piece 421, and the guide bracket 41 is sleeved on the ear piece 421. The lower part of the guide bracket 41 has a sliding rod 411 on each side. The sliding rod 411 is sleeved in the ear piece 421. A spring (not shown in the figure) is sleeved on the sliding rod 411. The spring adaptively adjusts the height of the guide bracket 41. A guide groove 412 is provided in the top of the guide bracket 41. The guide groove 412 passes through the wire and guides the wire to the iron core 32 for winding. Both ends of the guide groove 412 have arc grooves 413. The arc grooves 413 play a transition role in the direction of the wire at both ends of the guide groove 412 to prevent the wire from being scratched.

[0027] The working principle of the present invention is: this embodiment drives the entire device only through a set of driving mechanisms, the active bevel gear 21 drives the entire transmission screw 22 to rotate through the driven bevel gear 221, the transmission screw 22 drives the outer driven pulley 33 to rotate through the outer output pulley 222, and then drives the winding part 30 to rotate, the transmission screw 22 drives the output rod 24 to rotate through the clamping part 23, the output rod 24 drives the follower screw 43 to rotate through the inner output pulley 242 and the belt 25, and the follower screw 43 drives the guide bracket 41 to move through the joint 42 to guide the wire and then wind it on the iron core 32.

[0028] It should be noted that the power source connected to the active bevel gear 21 should be a motor with forward and reverse rotation functions, the most common of which is a servo motor.

[0029] In addition, the pressing head 234 should have a certain width, which should be greater than one rotation cycle of the spiral 241, to ensure that the wire that has just been wound is always pressed during the wire winding process.

[0030] Furthermore, the spiral angles of the spiral tab 232 and the spiral 241 should avoid self-locking, otherwise the spiral tab 232 cannot drive the output rod 24 to rotate through the spiral 241 .

[0031] The above embodiments primarily illustrate the transformer coil winding apparatus of the present invention. While only a limited number of embodiments and technical features have been described, those skilled in the art will appreciate that the present invention may be implemented in numerous other forms without departing from its spirit and scope. Therefore, the illustrated embodiments are to be considered illustrative rather than restrictive, and the present invention may encompass various modifications and alternatives without departing from the spirit and scope of the present invention as defined by the appended claims.
