PURPOSE: A core discharge apparatus by vacuum suction is provided to easily discharge a core while not deforming the shape of an electrode assembly by fixing the electrode assembly through vacuum suction and to prevent capacity reduction and lifetime reduction. CONSTITUTION: A core discharge apparatus by vacuum suction in a lithium ion secondary battery comprises: a lifting member(700); a driving part(730) for driving the lifting member; a guide(720) guiding the lifting member; a suction plate(710) which extends from the front of the lifting member and vacuum-sucks an electrode assembly by going down with the lifting member; a core part which winds the electrode assembly at the external surface and is discharged to one side of the outside; and a conveyor belt(740). |
