Notching device for secondary battery

Abstract

The present disclosure relates to a notching device which include: a transporter transporting an electrode along a first direction; an encoder outputting a first signal along the first direction based on movement of the transporter; a signal generator outputting a second signal along a second direction among directions perpendicular to the first direction; a laser notching the electrode; and a controller controlling the layer to calibrate a first position along the first direction of the laser to a first calibration position using the first signal, calibrate a second position along the second direction of the laser to a second calibration position using the second signal, and notch the electrode at the first calibration position and the second calibration position.

Dependencies are inferred from the claim text.
