Document Type and Number:
WIPO Patent Application WO/2022/203292
Kind Code:
A1
Abstract:
The present invention may provide a lase notching apparatus 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 notch 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 of the laser irradiation unit such that a spot of the second beam follows a moving trajectory of a spot of the preceding first beam.
