Document Type and Number:
WIPO Patent Application WO/2021/096068
Kind Code:
A1
Abstract:
The present invention relates to an automatic electrode supply apparatus that automatically supplies electrodes in various processes for manufacturing a secondary battery, and an automatic electrode supply method using the automatic electrode supply apparatus. The automatic electrode supply apparatus comprises a first chuck splicing unit including a splicing unit in which a traveling electrode is located and a second chuck splicing unit including a splicing unit in which a stand-by electrode is located. The first and second chuck spicing units each include an EPC sensor for measuring positions of edges of the traveling electrode and the stand-by electrode in order to prevent defects such as misalignment or fracture of electrodes due to a position difference between the traveling electrode and the stand-by electrode.
