Abstract

The present invention relates to a lamination apparatus for a secondary battery, the lamination apparatus comprising: an electrode transfer unit for transferring one or more electrodes; a separator transfer unit for transferring one or more separators; a joining unit for joining the electrodes and the separators to each other such that the electrodes and the separators are arranged alternately from top to bottom, and transferring the joined electrodes and separators; and a position correction unit for correcting the position of the uppermost electrode placed at the top of the electrodes and separators joined by the joining unit to align the uppermost electrode with the set position of the separators.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims the benefit of priority of Korean Patent Application No. 10-2019-0028023 filed on March 12, 2019, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a lamination device and a lamination method of a secondary battery, and more particularly, to a lamination device and a lamination method of a secondary battery that improve positional defects of an uppermost electrode disposed on the uppermost side. Background technique [0004] Generally, a secondary battery refers to a battery that is rechargeable and dischargeable, unlike a primary battery that is not rechargeable. Secondary batteries are widely used in high-tech electronics such as mobile phones, notebook computers, and camcorders. [0005] Such a secondary battery includes: an electrode assembly in which electrodes and separators are alternately laminated; a...
