Description

A square battery L glue sticking device Technical Field

The present invention belongs to the technical field of film coating equipment for square-shell batteries, and in particular relates to an L-glue pasting device for square-shell batteries.

Background technique

The square shell battery (hereinafter referred to as the battery), see Figure 1, is divided into six external surfaces, namely, the top surface 11, the bottom surface (not shown), the left large surface 12, the right large surface (not shown), the front side surface (not shown), and the rear side surface 13, according to the posture with the liquid injection port facing forward and the top surface facing upward. The positive pole 14, the liquid injection port 15, the explosion-proof window 16, the QR code 17, and the negative pole 18 are distributed from front to back on the center line of the top surface 11 (exposed surface of the top cover) of the conventional battery. In the process of battery manufacturing, the six external surfaces of the bare battery aluminum shell need to be covered with an insulating film (sheet) to play the role of electrical isolation, as well as anti-corrosion and decoration.

Generally, the insulating film is made into a double-layer film, that is, the adhesive side of the insulating film with adhesive on the back is adhered to the release film of equal width, and then cut into whole sheets of insulating film and stacked together for delivery, or rolled on a roll with the insulating film on the outside and the release film on the inside to make a double-layer film roll for delivery. Before wrapping, the double-layer film roll is released and the release film tape is peeled off, and the insulating film tape is pasted on the surface of the bare battery. During the wrapping process, it is cut into insulating film strips and then wrapped on the six surfaces of the bare square shell battery. The material of the insulating film (sheet) is polyethylene terephthalate (PET for short). The insulating film is generally 0.08~0.15mm thick, and the insulating sheet is generally 0.15~0.5mm thick. It 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, polyvinyl pyrrolidone), as thick as 0.01~0.05mm), which can be accelerated to solidify when exposed to ultraviolet light (UV), and has excellent insulation, high temperature resistance, flame retardancy, heat dissipation and viscosity.

L-glue is a short piece of insulating film tape that is attached to the L-shaped corner position of the top surface of the battery (mostly the edge of the top surface and the side surface), see L-glue 19 in Figure 1. The length of L-glue is equal to the length of the corner, and the width of the two sides (mostly the top surface and the side surface) at the corner position is equal and exceeds 4mm (minimum creepage distance), but is smaller than the minimum plane width of the four edges of the top surface, generally 5~6mm wide. L-glue is applied before film coating, which is used in the case where the battery side only needs to be half-wrapped instead of fully coated with insulating film to save insulating film. Before or during the process of applying L-glue, the insulating film tape must be cut into small pieces of insulating film tape.

Battery sticker L glue requirements:

(i) The length is equal to the length of the corners, and the effective width is ≥ 4mm;

(ii) Film sticking accuracy ±1mm;

(3) There is no debonding, bubbles, wrinkles, warping, scratches or dirt.
