NOVEL DEVICE FOR NOTCHING AND SECONDARY BATTERY PRODUCED BY USING SAME

摘要

The present invention provides a device for notching, which is a device for notching an electrode sheet in intervals corresponding to the distance between unit electrodes, for manufacturing a plurality of unit electrodes from the electrode sheet which is continuous and is coated on one side or both sides with electrode active material, and comprises: a press for punching notches on the upper end and the lower end of the electrode sheet while the electrode sheet is fixed in a position; and two or more grippers, which are located behind the press based on the direction in which the electrode sheet is supplied, for receiving and transferring the electrode sheet, one pitch at a time according to the movement of the press, the one pitch being a size which corresponds to the unit electrode, wherein when one gripper from the grippers receives and transfers the electrode sheet, the other grippers move to a receiving position.
