Description

Technical Field

[0001] The utility model relates to the field of film punching machines, in particular to a film punching machine for forming aluminum-plastic films of lithium battery soft-pack batteries. Background Art

[0002] As the key packaging material for soft-pack lithium batteries, the aluminum-plastic film for lithium battery soft-pack batteries is mainly composed of three layers of materials: ON (outer nylon layer), AL (middle aluminum layer), and CPP (inner heat-sealing layer). It has excellent barrier properties, deep punching, puncture resistance, electrolyte resistance, and insulation. This aluminum-plastic film has a wide range of applications, not only covering 3C digital products such as smart phones, tablet computers, smart wearable devices, etc., but also widely used in power fields such as electric vehicles, hybrid vehicles, and energy storage fields such as grid energy storage and household energy storage.

[0003] In the production process of soft-pack lithium batteries, the aluminum-plastic film needs to be processed by a forming and punching machine to form a battery shell that meets the requirements. The existing lithium battery soft-pack battery aluminum-plastic film forming and punching machine is mainly composed of a frame, a feeding mechanism, a punching mechanism, a mold, a coding mechanism, a cutting mechanism, etc. In the punching process, the aluminum-plastic film is transported into the punching area through the feeding mechanism, and the punching mechanism impacts the aluminum-plastic film in accordance with the preset program and matches with the mold to form a lithium battery shell. After the coding mechanism engraves the aluminum-plastic film, it is cut by the cutting mechanism.

[0004] However, there are still some defects in the processing of aluminum-plastic film by the existing forming and punching machines. 1. The existing punching machines can usually complete the feeding, punching, pressing guide, coding and cutting of the aluminum-plastic film. However, after the existing punching machines complete the cutting, the cut aluminum-plastic film usually falls directly into a storage device such as a trough or a hopper for collection. The existing structure for collecting the cut aluminum-plastic film is relatively simple and lacks an orderly arrangement and separation mechanism, which causes the aluminum-plastic film to accumulate and pile up in a chaotic manner in the collection area, thereby increasing the subsequent sorting and classification work, and may also cause surface damage due to the mutual friction between the aluminum-plastic films, thereby affecting the work efficiency and production quality of the production and processing of the aluminum-plastic film; 2. Due to the normal temperature setting of the aluminum-plastic film, the normal temperature punching and molding of the aluminum-plastic film by the existing punching machines is easy to cause the aluminum-plastic film to be stretched and damaged, resulting in insufficient ductility of the aluminum-plastic film, affecting the molding quality.
