Description

Technical Field

[0001] This utility model belongs to the technical field of battery packing equipment, and in particular relates to a horizontal labeling cylindrical battery packing machine. Background Technology

[0002] Cylindrical battery 10 is a single cylindrical primary cell, please see... Figure 1 A cylindrical battery includes a cylinder 11 and a positive electrode post 12. The model of the cylindrical battery 10 is defined by the diameter and height of the cylinder; for example, 4695 indicates that the cylinder diameter D is 46±0.2mm and the height H is 95±0.5mm. During the manufacturing process, the cylindrical surface of the bare cylindrical battery 10's metal casing 11 needs to be completely covered with an insulating film to provide electrical isolation, as well as corrosion protection and decoration. Covering the cylindrical battery 10 with an insulating film is an indispensable step in the battery production process.

[0003] The general insulating film is supplied in the form of double-layer film tape roll 20A. The back of the insulating film tape is prepared with adhesive. First, the back of the insulating film tape is adhered to the release film tape 22 of the same width to form a double-layer film tape 20. Then, the double-layer film tape 20 is wound on a roll with the insulating film tape on the outside and the release film tape 22 on the inside to form a double-layer film tape roll 20A. The insulating film tape is made of polyethylene terephthalate (PET), and is generally 0.08~0.15mm thick. It has excellent insulation, high temperature resistance, flame retardancy, heat dissipation, and tensile rigidity. The adhesive is a polymer binder (one or more of polyvinylidene fluoride-hexafluoropropylene copolymer, polyvinylidene fluoride, polymethyl methacrylate, polyethylene oxide, polyacrylonitrile, polystyrene, polyvinyl acetate, and polyvinylpyrrolidone). The adhesive layer is generally 0.01~0.05mm thick and has excellent insulation, high temperature resistance, flame retardancy, heat dissipation, and adhesion. The release film tape 22 is made of polyethylene (PE), and is generally 0.05~0.1mm thick. The roll can be made of paper or rubber, and can also be used for recycling the release film tape 22.

[0004] When using the insulating film tape, unfold the double-layer film tape roll 20A, peel the insulating film tape off the release film tape 22, and wrap and stick it to the cylindrical surface of the cylindrical battery 10. Before or after sticking the insulating film tape, cut the insulating film tape into insulating film tape segments 21. Alternatively, the insulating film tape segments 21 can be pasted onto the release film tape 22 like stickers. When using the insulating film tape, unfold the double-layer film tape roll 20A and peel the insulating film tape segments 21 off the release film tape 22.

[0005] Requirements for applying film to cylindrical batteries:

[0006] (a) See Figure 1 The diameter D of the cylindrical battery 10 is 46mm, and the compatible height H is 80~120mm;

[0007] (ii) See Figure 1 The insulating film strip 21 covers the entire cylindrical surface of the cylinder 11 of the battery 10 to form an overlapping surface 211; the width A of the overlapping surface 211 is ≥4mm (minimum creepage distance).

[0008] (iii) Membrane tension 1.5±0.5 kgf, film application pressure 15±5 kgf;

[0009] (iv) After the cylindrical battery is coated, there are no defects such as exposed surfaces (except for intentionally left blank), delamination, bubbles, wrinkles, lifting, scratches, or dirt on the cylindrical surface.

[0010] To address this, a horizontal labeling cylindrical battery film applicator was developed for applying film to cylindrical batteries 10. Summary of the Invention
