  "textContent": "The present invention relates to a device for removing scraps after laser notching of a film forming unit of a secondary battery for an electric vehicle, and to completing a jelly roll in which flags are not overlapped by clearly removing particles generated during notching jointly with accurately separating and discharging a scram part by ultraprecision injection through multiple air nozzles when forming a flag shape by notching an uncoated part without coating of a cathode and an anode in a trapezoidal shape by a laser in a secondary battery for an electric vehicle configured by stacking an electrode roll in a circular box. The present invention is configured to include a winding unit and rollers to unrolling and transporting a rolled electrode, a laser notching unit making a flag shape by notching to an uncoated portion of the electrode transported through the roller , an air nozzle unit for separating discharging a scrap by injecting air to the uncoated portion of the electrode notched by the laser notching unit , and a collection unit for strongly suctioning and discharging the scrap separated and discharged by the air nozzle unit by air.",
