  • Patent number: 11839993
    Abstract: Discussed is an apparatus for notching an electrode sheet, the apparatus including a transfer unit having first and second transfer rollers provided on a bottom surface of the electrode sheet to transfer the electrode sheet at regular intervals, a jig unit provided below the electrode sheet, and supporting the bottom surface of the non-coating portion and a notching unit provided above the electrode sheet to notch the non-coating portion supported on the jig unit to provide the electrode tab, wherein the jig unit includes a rotation member provided between the first and second transfer rollers and rotated in a direction perpendicular to a transfer direction of the electrode sheet, two or more jigs provided on an outer circumferential surface of the rotation member to alternately support the non-coating portion disposed between the first and second transfer rollers when the rotation member is rotated.
    Type: Grant
