Battery coating edge cutting and folding patch production line and coating edge cutting and folding patch process thereof

Abstract

The battery coating edge cutting and folding patch production line comprises a coating part, a circulating transmission part, a film processing part and a detection discharging part, and the circulating transmission part comprises two single-rail lines arranged in parallel at an interval and jig transverse moving mechanisms arranged at the two ends of the two single-rail lines; the film coating part is arranged on one side of the monorail line and comprises a film releasing device and a film coating device which are arranged up and down; the film processing part is arranged on the monorail line and comprises an edge cutting mechanism, an edge folding mechanism, a hot pressing mechanism and a surface mounting mechanism which are sequentially arranged along the monorail line. According to the invention, the belt-shaped blue film can be automatically separated from the protective film and can be automatically cached and guided out, the belt-shaped blue film can finish automatic coating of the blue film in synchronous battery transmission, the jig carries the battery to finish automatic edge cutting, edge folding and insulation sheet pasting among the stations, the jig circulates and flows back, the capacity of the whole line is improved, and automatic full coating of the outer side of the battery is realized.

Description

technical field [0001] The invention relates to the field of automated production, in particular to a production line for cutting, folding, and pasting of battery film and its film cutting, folding and pasting process, which is suitable for automatic production and is used for the film processing of electric cores on an automated production line. Background technique [0002] As the country vigorously promotes the development of new energy, the demand for lithium-ion power batteries in all walks of life is increasing. In the post-production process of lithium-ion power batteries, the exterior of the battery needs to be coated with a blue film. The main function of the blue film is to protect the battery. , to avoid battery exterior scratches or electrolyte corrosion. The battery coating automation production line includes the coating section process and the post-coating process as a whole. The battery is coated with blue film in the coating section process. In the post-coati...

Problems solved by technology

[0006]1. The problem of cutting off the blue film after coating: Since the incoming material of the blue film is generally a strip-shaped structure, in the process of the coating section, the strip-shaped blue film is along the In the direction of battery transmission, the left, right, upper, lower, and four sides of the battery are completely coated. In addition, the front and rear sides are not coated with blue film, and the blue film extends to the outside at the front and rear sides of the battery. Therefore, in the post-process of blue film coating , it is necessary to bend and cover the blue film extending outward on the front and rear sides of the battery to the front and rear side walls of the battery, and the blue film extending to the outside of the battery is in a continuous state, and the blue films on different sides will overlap each other when bending Bending affects the flatness of the bending. Therefore, before bending the epitaxial part of the blue film, the problem of automatic cutting of the epitaxial part of the blue film needs to be solved;

[0007]2. The problem of bending and pressing after the blue film is cut: In the later stage of the blue film coating process, it is necessary to fold the blue film extending outward from the front and rear sides of the battery. Bending is wrapped on the front and rear side walls of the battery, and the blue film extending to the outside of the battery is in a continuous state. When bending, the blue films on different sides will overlap each other and affect the flatness of the bending. Therefore, the blue film epitaxial part is folded Before bending, it will first be cut into a sheet-shaped blue film extending outward along the top, bottom, left, and right sides of the battery; Covering the problem, so that the sheet-shaped blue film is flatly bent and pressed on the front and rear end walls of the battery

[0008]3. The problem of automatic attachment of insulating sheet on the uncoated surface of the battery: Since the blue film incoming material is generally a strip structure, in the coating automatic production line, the strip The blue film covers the four sides of the battery along the battery transmission direction, and the other two sides are in the state of uncoated blue film. Therefore, in the later stage of blue film coating process, it is necessary to attach insulating sheet to ensure battery encapsulation integrity
