Description

Technical Field

[0001] The present invention belongs to the technical field of blade battery production, and in particular relates to a blade battery coating machine. Background Art

[0002] Compared with ordinary square shell batteries, the blade battery 10 is a flat and long battery, and its positive and negative poles are respectively located on the end surfaces of the two flat and long ends, including an upper large surface 11, a lower large surface (not shown), a left end surface 12, a right end surface 13, a front side surface 14 and a rear side surface 15. Figure 1-2 As shown, the left end face 12 is provided with an explosion-proof window 16 and an anode column 17, and the right end face 13 is provided with a liquid injection port 18, a QR code 19 and a cathode column 20. During the production process of the blade battery 10, an insulating film needs to be coated on the outer surface of the battery to prevent the blade battery 10 from being scratched.

[0003] Insulating film is needed in the film wrapping process. Generally, insulating film materials are made into two forms: single insulating film (insulating film sheet) and long insulating film tape. Generally, the sticky side of the insulating film with adhesive on the back is adhered to the release film of the same size. Insulating film sheets are stacked together and supplied in piles, and insulating film tapes are rolled on reels to make double-layer film tape rolls for supply. Insulating film sheets can be used by peeling off the release film sheets before film wrapping. Insulating film tapes need to be peeled off the release film tape before film wrapping and cut into insulating film tape segments during the film wrapping process. The head of the insulating film tape refers to the end of the insulating film tape or the insulating film tape segment that is separated from the double-layer film roll first, and the tail of the insulating film tape refers to the end of the insulating film tape or the insulating film tape segment that is separated from the double-layer film roll later, which is the other end of the insulating tape segment. In this article, where there is no need to distinguish between insulating film sheets and insulating film strips, they are collectively referred to as insulating films. The material of the insulating film (sheet) is polyethylene terephthalate (also known as PET). 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, and polyvinyl pyrrolidone), as thick as 0.01~0.05mm), which can accelerate solidification when exposed to ultraviolet light (UV), and has excellent insulation, high temperature resistance, flame retardancy, heat dissipation and viscosity; the material of the release film is polyethylene (also known as PE), and the release film is generally 0.05~0.1mm thick.

[0004] The insulating film tape is used to cover the six housing surfaces of the battery in the form of paving some surfaces to form paved surfaces, and folding the remaining surfaces with the insulating film extending from the paved surfaces to form folded surfaces.

[0005] In the prior art, some battery shell surfaces are paved with insulating film, and then the insulating film strip is cut during the film pasting process; before folding and pasting, the insulating film extending out of the four corners of the bottom surface of the battery is notched or cut near the four corners to prevent the adhesive surface of the insulating film from being forced to overlap itself during folding and pasting, and from being unable to be pasted to the battery shell surface, resulting in folding and warping; finally, the insulating sheet is pasted on the top surface of the battery.

[0006] Blade battery 10 coating requirements:

[0007] 1. The six shell surfaces of the battery are covered as required. The left end surface 12 and the right end surface 13 of the blade battery 10 are generally bare surfaces, and the upper large surface 11, the lower large surface, the front side surface 14 and the rear side surface 15 of the blade battery 10 are generally fully covered surfaces. Alternatively, the upper large surface 11, the lower large surface, the front side surface 14 and a part of the rear side surface 15 of the blade battery may be fully covered surfaces, and the remaining parts may be half-covered surfaces;

[0008] 2. Film sticking accuracy ±1mm;

[0009] 3. No exposure (unless intentionally exposed), debonding, bubbles, wrinkles, corners, warping, scratches, or dirt.

[0010] 4. The insulation requirement of the film is that the creepage distance from any point on the film surface (except the top surface) after the battery is film-coated to the battery shell surface must be ≥4mm, and 4mm is called the minimum safe creepage distance. For this reason, the shortcut (a straight line distance or the sum of the shortest multiple straight line distances) from any point on the edge of the exposed edge of the insulating film on the full-wrapped surface (including the original edge of the insulating film, the edge of the cut tape, the edge of the cut, and the edge of the cut) to reach any part of the surface of the shell of the full-wrapped surface through the film and the film overlap bonding area is called the creepage distance from the film edge to the shell surface, which must be ≥4mm; and the shortcut (a straight line distance or the sum of the shortest multiple straight line distances) from any point on the full-wrapped surface to any shell surface that needs to be exposed or half-wrapped through the bonding area between the film of the full-wrapped surface and the exposed surface or half-wrapped surface is called the creepage distance from the full-wrapped surface to the shell surface of the other side that needs to be exposed or half-wrapped surface, which must be ≥4mm.

[0011] 5. The length and width dimensions are not significantly increased so as not to affect the future battery module assembly.

It can be understood that the setting of the two clamping claws 73232 can achieve the clamping of the left and right ends of the front and rear sides of the blade battery 10, so as to increase the stability of the clamping of the clamping claws 73232.

[0108] Specifically, the clamping jaw 73232 includes a side clamping portion 732321 and a large surface clamping portion 732322.

It can be understood that when the manipulator clamp 732 clamps the blade battery 10 and the clamp abutting member 733 abuts the blade battery 10, the clamp lifting adjustment member 7322 can play a certain buffering role to avoid clamping too tightly to damage the battery surface, and can also adjust the clamping gap in the vertical direction of the clamp unit 73202 to be suitable for clamping blade batteries 10 of various thicknesses.

[0110] In this embodiment, the clamp lifting and adjusting component 7322 further includes a lifting and adjusting stroke switch 73226 and a lifting and adjusting stroke switch sensing piece 73227.
