Polymer soft package lithium battery aluminum plastic film shell punching and trimming die

Abstract

The invention discloses a polymer soft package lithium battery aluminum plastic film shell punching and trimming die, and relates to the technical field of automatic production equipment of lithium batteries. The shell punching and trimming die for the aluminum-plastic film of the polymer soft package lithium battery comprises a material placing plate used for placing materials, a liftable material pressing plate used for extruding the materials on the material placing plate, a guide part used for guiding the material pressing plate in the lifting process, and a punch assembly used for punching the materials on the material placing plate out of a pit body model. The guide assembly is used for guiding the punch assembly, the trimming assembly is used for trimming materials punched out of the pit body model through the punch assembly, and the waste collecting box is used for collecting waste obtained after trimming of the trimming assembly. Through mutual cooperation of the discharging plate, the pressing plate, the punch assembly and the edge cutting assembly, model stamping and edge cutting operation of an aluminum plastic film of a polymer soft package battery are achieved, the product packaging size accuracy is improved, and the rejection rate is reduced.

Description

technical field [0001] The invention relates to the technology in the field of lithium battery automatic production equipment, in particular to an aluminum-plastic film shell punching and trimming die for a polymer soft-pack lithium battery. Background technique [0002] Lithium polymer soft pack battery (Li-polymer, also known as polymer lithium battery): it is also a kind of lithium ion battery, but compared with liquid lithium battery (Li-ion), it has high energy density, smaller size, ultra- It is a new type of battery with obvious advantages such as thinning, light weight, and high safety. The aluminum-plastic film of the polymer pouch battery is usually produced by stamping, stretching and other processes. The products punched out of similar molds in the market have undergone multiple processes and manual trimming (manual, fixtures and other small punching equipment), which solves the problem of previous products. There are big problems in the process such as position...
