[0022] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] Example:

[0024] As shown in the attached Figure 1 to the attached Figure 4 shown:

[0025] The present utility model provides a wire winding mechanism for a leakage coil skeleton, including a base plate 11, two groups of bearing seats 12 arranged on the base plate 11 and a rotatable material hub 13, which provides a stable basis for the supply and transportation of wire; the material hub 13 can smoothly surround the wire, ensuring that the wire will not be entangled or knotted during high-speed operation; secondly, a workbench 14 is arranged on the top of the base plate 11, and a tension adjustment assembly is arranged on the top of the workbench 14. The tension adjustment assembly includes a pressing roller 21, and the pressing roller 21 can control the winding tightness of the wire, ensuring the uniformity and tightness of each winding; by adjusting the position of the pressing roller 21, the tension of the wire can be controlled in real time, avoiding the problems of wire loosening or excessive stretching, and further ensuring the more stable and reliable electromagnetic performance inside the leakage coil; in addition, a winding assembly is also arranged on the top of the workbench 14.

[0026] Please refer to asFigure 2 , Figure 3 As shown in Figure 4 , a wire passing hole 22 is provided at the top of the workbench 14 for guiding and threading the wire. A wire collecting cover 23 is arranged at the bottom of the wire passing hole 22, which plays a role in guiding the wire to pass through. During the wire winding process, the wire will first pass through the wire collecting cover 23 and then be threaded through the wire passing hole 22. It can not only effectively guide the wire direction, avoid the problems of wire chaos and entanglement during high-speed operation, but also ensure that the wire maintains a good state and direction when entering the winding area. The setting of the wire collecting cover 23 greatly improves the stability and reliability of the winding process, ensures the winding quality of the wire, and improves the stability.

[0027] Please refer to Figure 3 as shown in Figure 4 , the tension adjusting assembly further includes two sets of fixed pulleys 24. A gantry 25 is arranged on the top of the workbench 14. Two sets of first mounting brackets 26 are respectively installed inside the gantry 25 and on the top of the workbench 14. The two sets of first mounting brackets 26 are both installed with rollable fixed pulleys 24, which can effectively adjust the tension of the wire, ensure that the tension of the wire is within a suitable range during the winding process, and avoid problems with the winding quality of the coil caused by too large or too small tension. The rollability of the fixed pulley 24 also ensures that the wire can slide smoothly when passing through, further improving the stability and reliability of the entire winding mechanism.

[0028] Please refer to Figure 4 as shown in

[0029] Please refer to Figure 1 as shown in Figure 2As shown, the winding assembly includes a linear slide rail 31. The linear slide rail 31 is provided at the top of the workbench 14. A slidable slider 32 is installed on the linear slide rail 31. An installation column 33 is provided at the top of the slider 32, and a winding motor 34 is installed at the top end of the installation column 33. The coil bobbin 35 is directly clamped on the main shaft of the winding motor 34, integrating the winding motor 34 and the coil bobbin 35 together, enabling them to slide along the linear slide rail 31, so as to realize the winding of the wire on the coil bobbin 35. The slidability of the slider 32 not only ensures that the winding motor 34 can move flexibly on the workbench 14, but also can conveniently adjust the relative position of the winding motor 34 and the coil bobbin 35, thereby finely regulating the tension and alignment state during the winding process.

[0030] Please refer to as Figure 2 As shown, the winding assembly further includes a lead screw slide table 36. The lead screw slide table 36 is also installed at the top of the workbench 14. The sliding block of the lead screw slide table 36 is fixedly connected to the aforementioned slider 32 through a connecting plate 37. During the winding process, the winding motor 34 is started, so that the coil bobbin 35 can rotate accordingly, driving the wire to be wound on the bobbin. At the same time, the driving motor 38 needs to be started. It can drive the sliding block on the lead screw slide table 36 to move along the connecting plate 37, thereby driving the slider 32 to displace. The displacement of the slider 32 will drive the entire winding motor 34 to displace on the linear slide rail 31, so that the wire can be evenly wound on the surface of the coil bobbin 35, avoiding quality problems caused by too fast or too slow winding speed, and ensuring the winding quality and consistency of the leakage-proof coil bobbin 35.

[0031] Please refer to as Figure 2 As shown, a driving motor 38 is provided at one end of the lead screw slide table 36. The function of this driving motor 38 is to push the sliding block on the lead screw slide table 36 to move along the connecting plate 37, thereby driving the entire slider 32 to displace. The displacement of the slider 32 will drive the winding motor 34 and the coil bobbin 35 installed thereon to translate on the linear slide rail 31, so that the wire can be evenly wound on the surface of the coil bobbin 35.
