Abstract
An electrode sheet notching apparatus includes: a conveying unit comprising a first roller and a second roller for conveying the electrode sheet; a jig unit comprising a jig for supporting the electrode sheet; and a processing unit comprising a laser for processing the electrode sheet. The jig has a slit formed on a surface facing the electrode sheet, and the laser beam, which processed the electrode sheet, moves on a plane coplanar with one surface of the electrode sheet to pass through the slit.
Claims14
An electrode sheet notching apparatus, comprising:
- a conveying unit including a first roller and a second roller, the conveying unit being configured to convey an electrode sheet;
- a jig unit including a jig, the jig being configured to support the electrode sheet;
- and
- a processing unit including a laser, the laser being configured to process the electrode sheet;
- wherein the jig has a slit positioned on a first surface of the jig facing the electrode sheet, the jig being configured to move on a plane coplanar with a first surface of the electrode sheet, the first surface of the electrode sheet facing the jig, wherein the slit is configured to allow passage of a laser beam.
An electrode sheet notching method comprising:
- rotating a first roller and a second roller to convey an electrode sheet;
- moving a jig having a slit positioned on a first surface of the jig, the first surface of the jig facing the electrode sheet and extending along a plane coplanar with a first surface of the electrode sheet so that a scheduled region of the electrode sheet to be processed and the slit overlap;
- and
- processing the electrode sheet by a laser.
