[0028] Specifically, when the insulating rubber sleeve is outside the battery, first start the fan 13, the suction generated by the fan 13, the outside air through the air inlet cover 12 is sucked into the air, the air is then delivered to the inside of the heating box 10, the air into the heating box 10, first through the filter plate 14 for filtering, filter plate 14 can effectively remove dust, impurities and particles in the air, then, the filtered air will be heated by heating wire 15, heating wire 15 by the electric energy quickly heating, and the heat transfer to the air, to ensure that the air to the required high temperature state, heated air through the delivery pipe 16 to the air outlet 17, finally, the heated air through the air outlet 17, and the battery outside the insulating rubber heating, the heating process can ensure that the pvc film on the surface of the battery evenly, avoid the pvc film and battery shell between the gap or bubble, thereby effectively improving the electrical isolation performance of the battery pack, thereby prolonging the service life of the battery.
[0029] With reference to Figures 3-5 The replacement assembly comprises a mounting block 21 fixedly connected to the front side of the heating box 10, a rotating rod 22 rotatably connected in the mounting block 21, a rotating plate 23 rotatably connected to the outside of the rotating rod 22, a clamping block 26 fixedly connected to the left side of the outside of the rotating plate 23, a spring 24 fixedly connected to the middle of the rotating plate 23, the bottom of the spring 24 fixedly connected to the middle of the mounting block 21, a handle 25 fixedly connected to the front side of the outside of the rotating plate 23, the handle 25 is convenient for the operator to use, the filter plate 14 is provided with a clamping groove 27 on the outside, the clamping block 26 is clamped with the clamping groove 27, and the stability of the filter plate 14 is improved.
[0030] Specifically, when the filter plate 14 needs to be replaced, first, the operator pulls the handle 25, which drives the bottom-fixed rotating plate 23 to rotate along the outside of the rotating rod 22. During the rotation of the rotating plate 23, the left-side-fixed clamping block 26 will move synchronously. The clamping block 26 and the clamping groove 27 cooperate with each other. Through this movement, the clamping block 26 gradually separates from the inside of the clamping groove 27. At the same time, the movement of the rotating plate 23 also stretches the middle-fixed spring 24, causing the spring 24 to deform. The stretching of the spring 24 not only makes the clamping block 26 separate from the clamping groove 27, but also provides sufficient counterforce. When the clamping block 26 completely separates from the clamping groove 27, the filter plate 14 can be easily taken out from the inside of the heating box 10. At this time, the operator can clean the filter plate 14. Cleaning the filter plate 14 can prevent the air flow from being limited, avoid the heating efficiency from being reduced, ensure that the air circulation of the heating box 10 is not hindered, and thus ensure the uniform heating effect during heating. When installing a new filter plate 14, the operator easily inserts the filter plate 14 into the inside of the heating box 10, then loosens the handle 25. At this time, the counterforce of the spring 24 will push the clamping block 26 to quickly rebound and re-clamp it into the inside of the clamping groove 27. At this time, the clamping block 26 firmly locks the filter plate 14, that is, the fixation of the filter plate 14 is completed. Cleaning the filter plate 14 can keep the air in the heating box 10 unobstructed, ensure that the air circulation is not hindered, avoid the heating efficiency from being reduced due to poor air flow, and thus ensure that the air in the heating box 10 is heated to the appropriate temperature, ensuring that the pvc film is uniformly heated, improving the quality of the battery wrapped pvc film.
[0031] Working principle: when the pvc film is wrapped around the outside of the battery, the fan 13 is started to generate suction to suck the external air into the inside of the heating box 10 through the fan 13, then the air is heated by the heating wire 15, and then the heated air is delivered to the air outlet 17 through the delivery pipe 16, and finally the air outlet 17 is discharged to uniformly heat the insulating glue outside the battery, ensuring that the adhesive tape is uniformly attached to the surface of the battery, which realizes uniform heating of the pvc film outside the battery when the battery is wrapped with the pvc film, avoids gaps or bubbles between the film and the battery shell, and thus ensures that it is firmly attached to the surface of the battery, thereby improving the service life of the battery.
[0032] When the filter plate 14 needs to be replaced, first, the handle 25 is pulled, the handle 25 rotates the bottom-fixed rotating plate 23 outside the rotating rod 22, and the outside left-fixed clamping block 26 moves when the rotating plate 23 rotates, and the spring 24 is stretched, and then, when the clamping block 26 is separated from the inside of the clamping groove 27, the filter plate 14 can be taken out from the inside of the heating box 10 for cleaning, when installation, the filter plate 14 is inserted into the inside of the heating box 10, then, the handle 25 is loosened, the clamping block 26 is clamped in the inside of the clamping groove 27 under the reaction force of the spring 24, the filter plate 14 in the inside of the heating box 10 can be conveniently disassembled and cleaned, the air is ensured to be unobstructed, the heating efficiency of the heating box 10 is maintained, the insulating glue is uniformly heated, and the production efficiency is improved.
[0033] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can be modified to the technical solutions recorded in the foregoing embodiments, or equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
