Abstract: A laser notching apparatus is presented, comprising: a laser irradiation unit including a first laser irradiating a first beam, a second laser irradiating a second beam, and an optical member which forms paths of the first beam and the second beam; and a control unit which moves a scanner of the laser irradiation unit along a notching line of an electrode, wherein the optical member forms the path of the first beam and the path of the second beam such that a first spot of the first beam and a second spot of the second beam are arranged apart from each other by a first distance on the notching line, and a size of the first spot is larger than a size of the second spot, and the control unit moves a reflective mirror such that a spot of the second beam follows a spot of the preceding first beam.

Abstract: A secondary battery manufacturing equipment comprises: a main body unit; a pair of electrode plate loading units, disposed in the main body unit to face each other, for supplying electrode plates of different polarities; an electrode plate transfer unit for transferring the electrode plates of different polarities, supplied from the pair of electrode plate loading units, to a set stacking position in an intersecting manner; a stacking unit installed in the main body unit to be disposed at the stacking position for horizontally reciprocating within a first distance range which is set as the electrode plates are transferred in an intersecting manner; a separator supply unit installed in the main body so as to be disposed above the stacking unit for horizontally reciprocating within a second distance range which is set such that a separator is interposed between the electrode plates that are transferred in an intersecting manner.
