A high-speed coating machine for cylindrical batteries

Abstract

The present invention provides a high-speed film coating machine for cylindrical batteries, comprising a machine platform, a film placing device, a feeding device, a film pulling and turning device, a film separating and feeding device, and a film pasting device. The high-speed film coating machine for cylindrical batteries of this solution sequentially feeds cylindrical batteries to the film pasting station where the film pasting device is located through the feeding device. The film pulling mechanism in the film pulling and turning device pulls the insulating film strip laid out by the film placing device onto two film turning mechanisms. The film cutting mechanism cuts the insulating film strip into insulating film strip segments. The film turning mechanism flips the insulating film strip segments onto the film separating and feeding device. The multiple film separating units of the film separating mechanism cut the insulating film strip segments into multiple insulating film sheets. The film feeding mechanism feeds the multiple insulating film sheets into the film pasting station, corresponding one-to-one to the film pasting units in the film pasting device. Multiple cylindrical batteries are coated simultaneously, and the film pulling operation and the film pasting operation can be performed simultaneously, thereby achieving high-speed film coating.

Figure 1 and Figure 2 , according to the cylinder's lying posture, it is divided into three outer surfaces: cylindrical surface 610, end surface 1 620, and end surface 2 630. On the end surface 1 620 of a conventional battery, an anode column 650 is arranged at the center of the circle, and explosion-proof windows 660, liquid injection port 670, and QR code 680 are arranged on both sides of the anode column 650; on the end surface 2 630, a cathode column 640 is arranged at the center of the circle, and explosion-proof windows 660 are arranged on both sides of the cathode column 640; the geometric specifications of the cylindrical battery 600 are defined by the cylinder diameter and height values. For example, 18650 refers to a cylinder diameter of 18±0.2mm and a height of 65±0.5mm. During the manufacturing process of the cylindrical battery 600, an insulating film strip segment 710 needs to be attached to the cylindrical surface 610 of the bare cell metal shell to achieve electrical isolation, as well as corrosion protection and decorative functions. Please see. Figure 3 Wrapping the cylindrical battery 600 with the insulating film strip 710 to form the coated battery 700 is an indispensable step in the production process of the battery 600.

[0003] Generally, the insulating film is made into a double-layer film tape. The adhesive side of the insulating film tape is adhered to the release film tape, and then the insulating film tape is stacked on the outside and the release film tape is stacked on the inside to form a double-layer film tape. The double-layer film tape is then rolled onto a reel to make a double-layer film tape roll. The insulating film tape is made of polyethylene terephthalate (PET), which is generally 0.08~0.15mm 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), and the glue layer is generally 0.01~0.05mm thick; the glue will not solidify for a long time under natural conditions, but the glue can be accelerated by ultraviolet light (UV) irradiation to solidify the glue, which has excellent insulation, high temperature resistance, flame retardancy, heat dissipation and adhesion; the release film tape is made of polyethylene (PE), which is generally 0.05~0.1mm thick; the reel uses a paper reel or a plastic reel, which is used to wind the double-layer film tape into a double-layer film tape roll and for recycling the wound release film tape into a release film tape roll.

[0006] Film tension 1.5±0.5kgf, film application pressure 15±5kgf;

[0007] The minimum dimension of the overlapping area of ​​the insulating film tape segment (minimum safe creepage distance) is 4mm;

[0008] The long diameter is not significantly increased to avoid affecting the future battery module assembly;

The film-pulling and film-turning device 300 of the present invention draws in the insulating film strip horizontally. After the film-cutting mechanism 340 cuts the film, the segments are rotated 90 degrees to a vertical position to accommodate the cylindrical battery 600 in the vertical position for film application. This saves space occupied by the film-pulling mechanism 330 and the film-applying device 500. Furthermore, the film-pulling and film-applying operations can be performed simultaneously, enabling high-speed film application.
