A punching machine for aluminum-plastic film for soft-pack lithium battery outer packaging

Abstract

The invention relates to a punching machine for aluminum-plastic film for the outer packaging of a soft-packed lithium battery, comprising a supporting base plate and a punching device, the punching device is installed on the top of the supporting base plate; the punching device includes a punching frame, a supporting hydraulic cylinder , supporting mobile body, supporting telescopic body, telescopic body spring, lateral branch chain, rolling branch chain, stamping hydraulic cylinder, stamping mechanism, mobile body connection block, mobile body push rod, push rod connection frame and stamping bracket; The rolling branch chain includes a rolling electric slider, a rolling push rod, a rolling connecting frame, a rolling shaft, a rolling wheel, a telescopic wheel and a rolling spring. The present invention can solve the problem that the stamping die existing in the stamping of the aluminum-plastic film of the outer packaging of the soft-packed lithium battery cannot be adjusted, the position around the aluminum-plastic film will be deformed when the aluminum-plastic film is stamped, and the stamping effect of the aluminum-plastic film is poor. Wait for the problem.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a punching machine for an aluminum-plastic film for the outer packaging of a soft-pack lithium battery. Background technique [0002] Soft-pack lithium battery is a kind of lithium battery. Soft-pack lithium battery is just a liquid lithium-ion battery covered with a polymer shell. When the air blows and cracks, the aluminum-plastic film needs to be stamped and formed first in the processing of the soft-packed lithium battery, so that the battery core can be placed in the stamping space. Existing small and medium-sized battery manufacturers generally use aluminum-plastic film when stamping It is carried out in a semi-automatic way, sometimes it is necessary to produce different types of soft pack batteries, and frequent replacement of stamping equipment is required, which reduces the production efficiency of soft pack batteries, and the aluminum plastic film on...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a punching machine for the aluminum-plastic film of the outer packaging of the soft-packed lithium battery, which can solve the problem that the existing stamping dies cannot adjust the punching size when the aluminum-plastic film of the outer packaging of the soft-packed lithium battery is stamped. , When the aluminum-plastic film is stamped, the position around the aluminum-plastic film will be deformed, and the stamping effect of the aluminum-plastic film is poor. When the plastic film is stamped, the position around the aluminum-plastic film will not be deformed, and the stamping effect of the aluminum-plastic film is good, etc.
