Title:
SECONDARY BATTERY ELECTRODE PRODUCTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/045772
Kind Code:
A1
Abstract:
The present invention relates to a secondary battery electrode production system. The secondary electrode production system according to the present invention comprises: an unwinding portion (100) having multiple electrode material supply reels so as to continuously supply an electrode material; a notching portion (200) disclosed on a path of movement of the electrode material supplied from the unwinding portion (100); a cutting portion (400) disposed on the path of movement of the electrode material supplied from the notching portion (200) so as to generate the electrode; a vision inspection portion (600) for confirming whether the electrode is acceptable or not; and an electrode discharge portion (800) comprising a magazine for aligning and storing the electrode while interworking with the vision inspection portion. The notching portion (200) comprises: a mold upper plate (201) disposed above the electrode material; a mold lower plate (202) disposed below the electrode material; and a driving portion (203) connected to the mold upper plate (201) and the mold lower plate (202), respectively, the driving portion (203) comprising a servomotor and a power transfer member for transferring power from the servomotor to the mold upper plate (201) and the mold lower plate (202), thereby simultaneously operating the mold upper plate (201) and the mold lower plate (202) upwards/downwards. Accordingly, an electrode tab can be formed by notching the electrode material.
