Discussed is an electrode notching device for a secondary battery, the electrode for a secondary battery, which is manufactured therethrough, and a secondary battery. The electrode notching device for the secondary battery, which notches a non-coating portion of an electrode sheet to provide an electrode tab, includes: a pair of notching molds configured to press and notch the electrode sheet; and a movement prevention roller part provided on pressing surfaces of the pair of notching molds to prevent the electrode sheet from moving when the electrode sheet is notched.

A device for punching and scoring a medium includes a punch tool and a grooved score guide. The punch tool has a cutter configured to cut an edge of a sheet of the medium. The positioning edge is disposed on the device and configured to guide an edge of the medium and position the medium with respect to the punch tool. The grooved score guide is formed in the device and configured to match a scoring tool to create a score line in the medium. The arrangement between the punch tool and positioning edge is configured to cut a notch in the edge of the medium at a notch point. The grooved score line is disposed in relationship to the punch tool to create the score line in the medium from the notch point across the medium.

A sheet punching device including: a die which has a die hole and is configured to be driven to rotate; a punch configured to move in and out of the die hole to punch a hole in a sheet; and a punch operating unit configured to reciprocate the punch with respect to the die hole in a state in which the punch is opposed to the die hole of the die, to move the punch in and out of the die hole.

An apparatus and method for manufacturing a notched corner board is disclosed. The method includes cutting bent board stock into fixed lengths; forming a slit in or near an end of the corner board; and bending/folding a part of the corner board between the end and the slit to create a notch or flap in the corner board. The apparatus includes one or more cutting tools configured to form a slit in or near a first end of the corner board, a support block configured to support the corner board as the slit is formed, one or more rollers configured to move the corner board towards the cutting tool(s), a frame to which the cutting tool(s), the support block, and the roller(s) are directly or indirectly attached, a motor, and a punch. The motor controls movement of the punch to form the notch in the corner board.

Discussed is an apparatus for manufacturing an electrode for a secondary battery, an electrode for a secondary battery which is manufactured therethrough, and a secondary battery. The apparatus notches a portion of a non-coating portion of an electrode collector, which is not coated with an electrode active material, in an electrode sheet coated with the electrode active material on the electrode collector to manufacture an electrode tab. The apparatus includes a notching roll that rotates to notch the portion of the non-coating portion, wherein the notching roll includes: a notching cutter provided on a portion of the notching roll, which faces the non-coating portion to notch the electrode sheet; and a roll pad provided on a portion of the notching roll, which faces the electrode active material, the roll pad contacting the electrode sheet when the notching roll rotates to prevent the electrode sheet from being slipped.
