Abstract: 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.

Abstract: The present invention relates to a flag forming device after laser notching of a secondary battery for an electric vehicle, and particularly, to a flag forming device after laser notching of a secondary battery for an electric vehicle configured by stacking electrode rolls within a circular box, which makes a flag shape by notching an uncoated portion having no coating of a negative electrode and a positive electrode with a laser, and makes the uncoated flag made by laser notching pass through a flag forming unit before winding to enable an uncoated tap to be folded inward.

Abstract: Disclosed is an integration wrapper capable of laser notching, including a spool unit (1) including an unwinding part on which materials of a roll form are capable of being installed, a transferring apparatus for moving electrodes in a specific length, and a tension apparatus capable of applying a tension, a plurality of laser notching units (2) disposed in a positive electrode and a negative electrode and driven to perform notching on the electrodes according to specific specifications of a tab form and interval when the electrodes are transferred by the transferring apparatus, and a wrapping unit (3) adapted to wind the notched materials located in a buffer unit and transferred by the transferring apparatus in a battery form by winding.

Abstract: The present invention relates to a winding conveying unit for an electrode plate of a rechargeable battery for an electric vehicle which can manufacture electric rolls by conveying and winding an electrode from the electric rolls without breakage when the electrode rolls are manufactured by using electrode rolls in which an electrode is configured in a direction to fill the electrode rolls in a box at a high integration in a manufacturing process of a rechargeable battery for an electric vehicle that is configured by stacking electrode rolls in a sealed (cylindrical or angular) box. The present invention provides a winding conveying unit for an electrode plate of a rechargeable battery for an electric vehicle, which can prevent a breakage when an electrode is conveyed, by providing a guide roller at a moving position of the electrode on an external surface of a conveying roller.
