Description

Technical Field

[0001] The present invention belongs to the technical field of square aluminum shell battery manufacturing equipment, and in particular relates to an insulating film belt feeding device for flipping and laminating square aluminum shell batteries. Background Art

[0002] During the manufacturing process of square aluminum shell batteries (hereinafter referred to as batteries), an insulating film needs to be attached to the six surfaces of the metal shell of the bare battery to make the bare battery into a coated battery to play the role of electrical isolation (insulation), as well as anti-corrosion and decoration. The industry calls it a battery film.

[0003] The material of the insulating film is polyethylene terephthalate (PET for short), which is generally 0.08 to 0.15 mm thick and has excellent insulation, high temperature resistance, flame retardancy, heat dissipation and tensile rigidity; the glue is a polymer binder (one or more of polyvinylidene fluoride-hexafluoropropylene copolymer, polyvinylidene fluoride, polymethyl methacrylate, polyethylene oxide, polyacrylonitrile, polystyrene, polyvinyl acetate, and polyvinyl pyrrolidone). The glue has excellent insulation, high temperature resistance, flame retardancy, heat dissipation and viscosity. The glue layer is generally 0.01 to 0.05 mm thick. The glue will not solidify for a long time under natural conditions, but the glue can be accelerated to solidify when exposed to ultraviolet light (UV).

[0004] See also Figure 2 Typically, the insulating film is fabricated in the form of an insulating film tape 221, with adhesive applied to the back of the insulating film tape 221. The adhesive-coated side of the insulating film tape 221 is adhered to a release film tape 222. The insulating film tape 221 is then stacked with the release film tape 222 on the inside and the insulating film tape 221 on the outside to form a double-layer film tape 22. The double-layer film tape 22 is then wound onto a reel 21 to form a double-layer film tape roll 20. During use, the release film tape 222 is peeled off and then typically rewound onto the reel 21 to form a release film roll 30 for recycling. The release film tape 222 is made of polyethylene (PE) and is typically 0.05 to 0.1 mm thick. The reel 21 is made of either paper or plastic.

[0005] The prior art uses a whole insulating film strip 221 for wrapping. The steps for covering the six shell surfaces of the battery are as follows: first, take some surface to make a paving surface, and then cut the insulating film strip 221 after paving to obtain the insulating film strip segment 221A. Figure 1 , is to take the left large surface, bottom surface and right large surface of the battery 10 and lay the insulating film tape 221 so that the left large surface, bottom surface and right large surface become the laying surface, thereby making the bare cell 10 into a film-coated battery 10A, and the remaining other surfaces of the film-coated battery 10A are as follows Figure 1The front side, rear side and top surface of the film battery 10A shown are folded and pasted with the insulating film extending from the paving surface to form a folded surface. After completion, a film-wrapped battery is obtained. According to the different paving surfaces of the battery, it is divided into a return film and a Figure 1 The U-shaped film shown is divided into a U-shaped film and a U-shaped film.

[0006] The laying principle is to use the relative movement of the battery 10 and the insulating film tape 20 to make the two contact linearly and simultaneously roll and stick them together to form a covering line and proceed continuously. The requirements for battery film are:

[0007] (1) During the lamination process, the insulation film tension is 1.5±0.5kgf and the lamination pressure is 15±5kgf;

[0008] (2) There is no glue, bubbles, wrinkles, scratches or dirt after the film is applied;

[0009] (3) The positioning accuracy of the insulating film strip edge and the battery surface after film pasting is ±1mm.

[0010] In the prior art, the main method of battery film pasting is to push the battery 10 lying flat against the insulating film strip 221 arranged approximately vertically and orthogonally, or to push the battery 10 upright against the insulating film strip 221 arranged approximately horizontally and orthogonally. However, at the moment of contact and rolling, the distance between the positioning line of the insulating film strip 221 and the pasting line of the insulating film strip 221, referred to as the fixed pasting distance, is relatively far, resulting in inaccurate positioning control of the insulating film strip 221 and a low pass rate of film pasting accuracy.

[0011] To this end, we provide a flip film laminating device with a short fixing distance that can improve the positioning control accuracy of the insulating film tape and thus improve the pass rate of film positioning accuracy. For this purpose, an insulating film tape feeding device for flip film laminating of square aluminum shell batteries is used to feed the insulating film tape 221 with a short fixing distance.

The film feeding translation mechanism 530 is arranged on the film feeding lifting mechanism 520 and is translated during the process of flipping and laminating. The lifting and lowering of the film feeding lifting mechanism 520 is coordinated with the translation of the film feeding translation mechanism 530. The insulating film strip 221 is fed in a short fixed laminating distance (marked as S) during the process of flipping and laminating. The film cutting mechanism 540 cuts the insulating film strip 221 after flipping and laminating, helping to complete the flipping and laminating of the battery 10 with qualified precision.
