Abstract

Disclosed is a leveling apparatus used in a cutting process after a forming process of a pouch-type secondary battery, the leveling apparatus including: a roller assembly having pairs of upper and lower rollers arranged in at least two rows to enable contacting and laminating the upper and lower surfaces adjacent to both edges of the pouch-type secondary battery on which the pouch-forming process is completely performed; and a supporting frame configured as a support roller assembly configured to be adjacent to the pouch-shaped Rolling is applied to upper and lower surfaces of both edges of the secondary battery, thereby relieving stress.

Description

technical field [0001] The present disclosure relates to a leveling device for manufacturing a pouch-type secondary battery, and more particularly, to a leveling device used in a pouch cutting process of a pouch-type secondary battery manufacturing process. [0002] This application claims priority from Korean Patent Application No. 10-2017-0034958 filed in Korea on March 20, 2017, the disclosure of which is incorporated herein by reference. Background technique [0003] In general, a method of manufacturing a pouch-type secondary battery includes the steps of: injecting electrolyte through an electrolyte injection portion located at one side of an edge region of the prepared pouch-type secondary battery; performing primary sealing of the electrolyte injection portion along a primary sealing line ; then perform charging / discharging; cut a part of the electrolyte injection part along a cutting line located inside the primary sealing line; perform degassing; perform secondary ...
