As a basic material for many key industries such as power transmission, motor manufacturing, and electronic equipment manufacturing, electromagnetic wire occupies an indispensable position in the modern industrial system. The uniformity of the insulation layer not only affects the stability of the insulation performance of electromagnetic wires, but also plays a key role in the safety and stability of equipment operation.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 As shown, a rapid impregnation and curing device for electromagnetic wire insulation includes an assembly shell 1. An impregnation tank 101 is located at the bottom of the assembly shell 1. The electromagnetic wire requiring impregnation needs to be removed from the impregnation tank 101. In actual use, a limiting device is needed to control the movement trajectory of the electromagnetic wire. The impregnation tank 101 contains impregnation varnish. A uniformizing device 2 is installed on the inner wall of the assembly shell 1. The uniformizing device 2 includes a carrier tube 201, one end of which is fixed to the inner wall of the assembly shell 1. The lower part of the carrier tube 201 is a vertical section. A snap-fit ​​shell 22 is installed on the side wall of the vertical section. A central uniformizing component 23 is rotatably snapped onto the snap-fit ​​shell 22. A drying device 3 is located above the uniformizing device 2. In practical applications, this device can be used repeatedly for repeated impregnation treatments. A power connector is provided on one side of the assembly shell 1 via a power cord.

[0025] like Figures 2-4 As shown, the snap-fit ​​shell 22 includes an intermediate tube 221 connected to the bearing tube 201, and an annular shell 222 connected to one side of the intermediate tube 221. One side of the annular shell 222 has a notch, and the inner wall of the annular shell 222 has an inner notch. The annular shell 222 is used to restrict the position of the central equalizing member 23, thus facilitating the introduction of airflow into the annular shell 222. The central equalizing member 23 includes a docking shell 231 snapped into the center of the annular shell 222. The upper part of the docking shell 231 gradually tapers inward, and a connecting cylinder 232 is fixed to the upper part of the docking shell 231. Both the connecting cylinder 232 and the docking shell 231 have through openings on one side, and air gaps are opened on the outer walls of both the docking shell 231 and the connecting cylinder 232. Hole 233 is provided to facilitate the placement of the electromagnetic wire inside the docking shell 231. A drive mechanism 4 for driving the center uniform component 23 is also installed on the inner wall of the assembly shell 1. The drive mechanism 4 includes a support plate 401. A drive gear 402 and a relay gear 403 are rotatably mounted on the bottom of the support plate 401. A force-bearing tooth 404 is fixed on the outer wall of the docking shell 231. The drive gear 402 and the relay gear 403 mesh with each other. A power motor 405 is fixed on the support plate 401. The output shaft of the power motor 405 is connected to the drive gear 402. The relay gear 403 and the force-bearing tooth 404 mesh with each other. This enables the center uniform component 23 to rotate stably.

[0026] like Figure 5 and Figure 6As shown, the drying device 3 includes a rotating shell 301. A bearing shaft is fixed to one side of the rotating shell 301 and is rotatably mounted on the inner wall of the assembly shell 1. A drying hole 302 is provided on the outer wall of the rotating shell 301. An inner shell 303 is provided inside the rotating shell 301. A heating element 304 is installed on the outer wall of the inner shell 303 to accelerate the curing speed. A support partition 305 is fixed on the outer wall of the rotating shell 301. The support partition 305 has a snap-fit ​​notch to facilitate the restriction of electromagnetic interference. The heating element 304 is an electric heating wire, and both ends of the electric heating wire are mounted on the inner shell 303 through the base plate. One end of the base plate is close to the inner wall of the rotating shell 301, so that the hot air can be ejected from the position near the location of the electromagnetic wire. An air outlet is provided on the outer wall of the inner shell 303. A vent pipe 306 is connected to one side of the inner shell 303. One end of the vent pipe 306 passes through the rotating shell 301 and the assembly shell 1, so that external air can be easily introduced into the vent pipe 306.

[0027] This device can quickly and uniformly process and cure the impregnated electromagnetic wire through the uniformizing device 2 and the drying device 3. The uniformizing device 2 can avoid uneven distribution of the impregnating varnish on the outside of the electromagnetic wire due to external factors, thus ensuring the quality of the finished electromagnetic wire insulation layer.

[0028] In use, this invention requires gas to be introduced into the vent pipe 306 and the carrier pipe 201. The impregnated magnetic wires enter the central uniform member 23 from bottom to top and are then wound around the support partition 305. During use, the gas inside the snap-fit ​​shell 22 can enter through the air hole 233 outside the docking shell 231 and then blow onto the electromagnetic wire. The drive motor drives the force-bearing tooth 404 to rotate through the relay gear 403, thereby making the docking shell 231 rotate stably. The airflow can be ejected through the air hole 233 on one side of the connecting cylinder 232. During the airflow process, the surface of the electromagnetic wire can be initially cured. The rotating central uniform member 23 can make the airflow blow evenly onto the electromagnetic wire. Then the electromagnetic wire can be wound around the support partition 305. The airflow in the vent pipe 306 can first pass through the heating member 304 and then be heated into hot airflow. Then it is blown onto the electromagnetic wire through the drying hole 302, thereby performing rapid curing treatment.
