Abstract
The present disclosure provides an apparatus for notching and a method for notching. The apparatus for notching includes at least one wire cutter that cuts at least one of a first side surface and a second side surface positioned opposite to the first side surface and at least one pattern cutter that cuts at least one of the first side surface and the second side surface to form a cut pattern, and the wire cutter is disposed to face the electrode plate along the first direction.
Claims20
An apparatus for notching, the apparatus comprising:
- at least one wire cutter that is configured to cut at least one of a first side surface of an electrode plate and a second side surface of the electrode plate that is opposite to the first side surface, with the cutting being along a direction in which the electrode plate moves in the apparatus;
- and
- at least one pattern cutter that is configured to cut at least one of the first side surface and the second side surface to form a cut pattern in the electrode plate,
- wherein the wire cutter is positioned to face the electrode plate along the direction in which the electrode plate moves.

An apparatus for notching, the apparatus comprising:
- at least one wire cutter that is configured to cut a first side surface of an electrode plate and a second side surface of the electrode plate that is opposite to the first side surface of the electrode plate, with the cutting being along a first direction in which the electrode plate moves in the apparatus;
- and
- at least one pattern cutter that is configured to cut at least one of the first side surface and the second side surface to form a cut pattern,
- wherein the wire cutter is positioned to face the electrode plate along the first direction,
- wherein a cutting edge of the wire cutter is configured to extend in a thickness direction of the electrode plate,
- wherein the wire cutter comprises a first wire cutter that is configured to cut the first side surface and a second wire cutter that is spaced a distance from the first wire cutter and is configured to cut the second side surface,
- wherein the distance between the first wire cutter and the second wire cutter is adjustable, and
- wherein the pattern cutter comprises a first pattern cutting element that cuts the electrode plate along a second direction and a second pattern cutting element that cuts the electrode plate along the first direction or a third direction that is different from the second direction.
5 more elements
A method for notching comprising:
- a first step of cutting an uncoated portion disposed on at least one of a first side surface of an electrode plate and a second side surface of the electrode plate that is positioned opposite to the first side surface, the cutting being along a direction that the electrode plate is moving, the cutting being performed by at least one wire cutter;
- and
- a second step of removing at least one of the uncoated portion disposed on one of the first side surface and the second side surface and a mixture portion, the removing being performed by using at least one pattern cutter to thereby form a cut pattern.
