  "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 1 and rollers 2 to 4 unrolling and transporting a rolled electrode, a laser notching unit 5 making a flag shape by notching to an uncoated portion of the electrode transported through the roller 4, an air nozzle unit 7 for separating discharging a scrap 10 by injecting air to the uncoated portion of the electrode notched by the laser notching unit 5, and a collection unit 8 for strongly suctioning and discharging the scrap separated and discharged by the air nozzle unit 7 by air.",
