[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0030] Please refer to Figures 1-3 ;

[0031] The utility model aims at providing a more flexible auxiliary mechanism, so that the winding equipment can have more use modes and adjustment modes, and the practicability is stronger, and specifically includes multi -axis mobile device 11, the multi -axis mobile device 11 has X axis and Z axis at least, preferably three -axis, or multi -axis movement mode such as mechanical hand, the Z axis mobile end of multi -axis mobile device 11 is installed with mobile platform 12, and the mobile platform 12 is installed with horizontal shift subassembly 13, and the direction of horizontal shift subassembly 13 is specifically according to actual production device, and specifically can be X axis or Y axis direction, and the mobile end of horizontal shift subassembly 13 is installed with pressure wire subassembly 14, and pressure wire subassembly 14 has a plurality of output ends downward, and different pressure tight members are arranged at a plurality of output ends respectively, and preferably, the pressure tight member can be a pressure block or a roller, and a winding clamp 2 is arranged below pressure wire subassembly 14, and the winding clamp 2 is also installed on the mobile end of Z axis with horizontal shift subassembly 13, that is, both will move synchronously, and the relative position does not change;

[0032] When working, the wire is introduced into the surface of the clamp 2 by the wire feeding device, and one end of the wire is fixed on the clamp 2, then the pressure wire subassembly 14 pushes the plurality of output ends to move downward, so that the pressure tight members abut against the clamp 2, and the wire is pressed on the surface of the clamp 2, then the clamp 2 is driven to rotate by the driving assembly, and the clamp 2 and the whole are pushed to move horizontally under the driving of the X axis of the multi-axis mobile device 11, so that the clamp 2 gradually changes position to make the wire flatly wind on the clamp 2;

[0033] When different thicknesses of wires are required according to production needs, first, the wire is introduced into the surface of the clamp 2 by the wire feeding device, and one end of the wire is fixed on the clamp 2, then the horizontal shift subassembly 13 drives the pressure wire subassembly 14 to move horizontally along the clamp 2, selects a pressure tight member with a suitable size, and the pressure tight member has a groove in addition to the size, which can better limit the position of the thin wire, and the larger pressure tight member can be made of rubber material; then the corresponding output end is controlled to move the pressure tight member downward to abut against the clamp 2, and the wire is pressed on the surface of the clamp 2, while the other output ends do not extend to avoid hindering the winding process;

[0034] In addition, some special transformers require the combination of thick and thin wires, which can be achieved by two different wire feeding devices to convey thick and thin wires, and by switching the size of the pressure tight member to realize winding without stripping, thereby improving production efficiency.

[0035] By adding an axis to the original mobile device, the specific needs of various winding processes of different products can be met, such as parallel winding, cross-winding positioning, wire bending at any position, etc., to realize the multifunctional needs of the equipment, and make the equipment more flexible.

[0036] Compared with the prior art, the technical scheme of the utility model sets one more axis, can change the relative position of the wire pressing assembly 14 and the clamp 2, thereby realizing the selection of the pressing part, making the mechanism action more flexible, and the wire pressing assembly 14 is provided with different types of pressing parts, can adapt to wires of different thicknesses, when different production workpieces are replaced, the pressing part does not need to be replaced, the downtime of the equipment is reduced, and the production efficiency is improved.

[0037] Further, since the sizes of the pressing parts are different, the radial position of the wire pressing assembly 14 relative to the clamp 2 also needs to be adjusted, for this purpose, the horizontal moving assembly 13 is slidably connected with the moving platform 12, the moving platform 12 is provided with a push-pull assembly 15, the output end of the push-pull assembly 15 is connected with the horizontal moving assembly 13, the moving direction of the push-pull assembly 15 and the horizontal moving assembly 13 is 90°, that is, the horizontal moving assembly 13 moves along the X axis, then the push-pull assembly 15 drives the horizontal moving assembly 13 to move along the Y axis.

[0038] The utility model discloses one of the embodiments of the horizontal moving assembly 13, and specifically includes a fixed beam 131, the fixed beam 131 is provided with a fixed frame 132, the fixed frame 132 is provided with a driving motor 133, the output end of the driving motor 133 is provided with a screw pair 134, the moving part of the screw pair 134 is provided with a moving beam 135, the moving beam 135 is slidably connected with the fixed beam 131, the wire pressing assembly 14 is installed at the end of the moving beam 135, the driving motor 133 drives the screw pair 134 to act, thereby realizing the telescopic action of the moving beam 135 relative to the fixed beam 131, so as to adjust the position of the wire pressing assembly 14, and moreover, the overall length can be shortened by adopting the stacking mode.

[0039] Further, the wire pressing assembly 14 is a multiple-output pneumatic assembly and has four output ends, for example, can be composed of four air cylinders, the four air cylinders are wrapped together by an outer cover, three output ends are arranged side by side, one pressing part 141 is arranged corresponding to each output end, the sizes of the three pressing parts 141 are different, the fourth output end is arranged relative to the three output ends and is provided with one large pressing part 142, the large pressing part is located behind the other three pressing parts, the length of the large pressing part covers the other three pressing parts, after winding is completed, the wire needs to be cut, the pressing part in the front needs to be moved upwards to make space for hanging the wire, at this time, the large pressing part behind extends to press the wire again, avoiding the wire from being scattered.

[0040] The clamp 2 in the prior art usually adopts a split design, as shown in Figure 4 The winding part 23 is split into two parts, and a slope 262 is designed, in use, the winding part 23 is formed by the slope 262 in combination with positioning and surrounding, and when the material is removed, the two parts are separated, so that the coil is more easily removed;

[0041] But in the process of recombination, two inclined surfaces 262 may be inaccurate alignment, resulting in failure to combine, in addition, the fixture 2 is a one-piece design, if in the process of combining impact damage, due to the use of inclined surface 262 design, it is difficult to process alone, so can only be scrapped.

[0042] The utility model discloses an embodiment of winding fixture 2, refer to Figures 5-9 , specifically includes the body 21, one end of body 21 is connecting portion 22, this connecting portion 22 is connected with drive assembly, the other end is winding portion 23, and the side edge end face of winding portion 23 is equipped with detachable end cover 24, and the axial position along winding portion 23 is equipped with gap 231, at least winding portion 23 is divided into two parts, and at least one part can be close to another part, the gap 231 in this embodiment starts from winding portion 23, and it only has one end to extend to the end face of winding portion 23, if a plurality of gaps 231 divide winding portion 23 into multiple parts to form claw shape, after exerting external force, close, after canceling external force, it can bounce out and restore state, in addition, as long as the radial length of winding portion 23 is reduced when stripping material, the coil can be easily stripped out, therefore, preferably, one gap 231 can be set, of course, also exclude multiple parts for separation state, but the bracket in these parts is provided with spring and other reset members, after closing, bounce out, after exerting external force, close, after canceling external force, it can bounce out and restore state, regardless of which way can still play the same technical effect;

[0043] In order to avoid the folding caused by the external force applied to the winding part 23 during winding, the gap 231 extends to the end surface of the winding part 23 and forms a clamping groove 232. During operation, the end cover 24 is installed at the end of the winding part 23, and the end cover 24 is provided with a limiting block 241 matched with the clamping groove 232 near the end surface of the winding part 23. Before winding, a paper sheet is wound on the winding part 23, and of course, it can be different according to the actual situation, which is not limited here. In addition, the end cover 24 functions to limit the distance and shape of the coil during winding. Since the two parts of the winding part 23 are limited from being folded by the limiting block 241, the inner diameter of the coil wound on the winding part 23 is the same as the outer diameter of the winding part 23 in the initial state, which also meets the standard of forming a coil. After completing the winding of the coil, the end cover 24 is separated from the winding part 23. Preferably, the end surface of the end cover 24 away from the winding part 23 is provided with an external hanging part 242 for clamping and fixing with an external device. The end cover 24 does not limit and block the coil, and then the coil can be transversely separated from the winding part 23. Since the coil is tightly wound on the winding part 23, and the two parts are separated from the limiting block 241 and the clamping groove 232, the radial distance of the two parts of the winding part 23 is reduced during the transverse separation process, so that the coil can be smoothly separated. After the coil is completely separated, the two parts of the winding part 23 are separated again and reset. After completion, the end cover 24 is again fixed on the end surface of the winding part 23 and limits the gap 231, and enters the next winding process.

[0044] In the above process, the winding part 23 maintains the same radial distance under the limitation of the limiting block 241 during winding. The radial distance of the winding part 23 is reduced by the gap 231 during the material separation process, making the material separation process simpler. The combination of the two components is integrated into one component in the utility model, and the traditional inclined surface 262 alignment structure is removed. Not only does the material separation process become simpler and more convenient, but also the end cover 24 is more quickly installed on the winding part 23. If the end cover 24 or the winding part 23 is damaged, the parts can be replaced individually, and the other part can still be used. However, due to the difficulty in processing, the inclined surface 262 structure requires very precise cooperation, so it cannot be used as a universal part, and it cannot be replaced at will. Therefore, the structure of the utility model has stronger universality.
