US 2022/0184875 A1 · Manufacturing Device Of Battery Case Having Improved Manufacturing Processability And Manufacturing Method Using The Same

Abstract

The present invention provides a manufacturing device of a battery case including a first mold including a first space part having a shape corresponding to a storage part formed therein; a second mold including a second space part having a shape corresponding to the storage part and a through-hole communicating with the second space part formed therein, and coupled to the first mold with a laminate sheet interposed therebetween; and an air pressure regulator mounted in the through-hole in a state in which the first space part and the second space part are isolated from the outside, and increasing or decreasing an air pressure of the second space part through the through-hole to stretch and modify the laminate sheet into a shape corresponding to the first space part or the second space part.

Dependent claims

A manufacturing method for forming a storage part for mounting an electrode assembly for a secondary battery on a laminate sheet, the manufacturing method comprising:

disposing the laminate sheet between a first mold and a second mold, and coupling the first mold and the second mold in a form in which a first space part having a shape corresponding to the storage part formed in the first mold and a second space part having a shape corresponding to the storage part formed in the second mold are isolated from each other;
changing a pressure of the second space part by a through-hole communicating with the second space part of the second mold and an air pressure regulator coupled to the through-hole;
and
stretching the sheet in a shape corresponding to the first space part or the second space part in response to a pressure change of the second space part.
