Abstract

The present invention provides a rolling device for a secondary battery, which corrects an outer shape of the secondary battery, the rolling device comprising: a jig member including a base plate, and one or more correction frames provided on a top surface of the base plate and into which the secondary battery is inserted; and a pressing member provided above the jig member to press the secondary battery inserted into each of the correction frames such that an outer shape of the secondary battery is corrected to coincide with an outer shape of the correction frame, in which the pressing member includes: a support configured to uniformly support an entire top surface of the secondary battery inserted into the correction frame, the entire top surface of the secondary battery inserted into the correction frame is pressed with a uniform force by the transmitted force, thereby correcting the outer shape of the secondary battery; and a pressing member configured to transmit a force such that the support member presses an entire top surface of the secondary battery inserted into the correction frame with a uniform force.

Description

technical field [0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2020-0021208 filed on Feb. 20, 2020, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a rolling device for a secondary battery, and more particularly, to a rolling device for a secondary battery capable of minimizing the thickness of the secondary battery. Background technique [0004] In general, a secondary battery refers to a rechargeable and dischargeable battery, unlike a non-rechargeable primary battery. Secondary batteries are widely used in high-tech electronic fields such as cell phones, notebook computers, and camcorders. [0005] Secondary batteries are classified into can-type secondary batteries in which electrode assemblies are built into metal cans and pouch-type secondary batteries in which electrode assemblies are built int...
