Abstract
An electrode sheet machining apparatus including a transfer roller configured to supply an electrode sheet, a drum located in contact with one surface of the supplied electrode sheet, and a laser radiator configured to radiate a laser beam toward the drum is provided. The drum includes a first drum configured to be rotated together with the supplied electrode sheet, a second drum located at a side of the first drum, the second drum, and a pattern jig removably mounted to the second drum, the pattern jig having an opening configured to allow the laser beam to pass therethrough.
Claims15
An electrode sheet machining apparatus comprising:
- at least one transfer roller configured to supply an electrode sheet;
- a drum configured to be in contact with one surface of the supplied electrode sheet;
- and
- a laser radiator configured to radiate a laser beam toward the drum,
- wherein the drum includes:
- a first drum configured to be rotated together with the supplied electrode sheet;
- a second drum located at a side of the first drum, the second drum configured to rotate or remain stationary;
- and
- a pattern jig removably mounted to the second drum, the pattern jig having an opening configured to allow the laser beam to pass therethrough.
An electrode sheet machining method comprising steps of:
- supplying an electrode sheet to a drum, the electrode sheet including a coated portion having an active material applied thereto and an uncoated portion located along one or each of opposite edges of the coated portion, the uncoated portion having no active material applied thereto;
- radiating a laser beam to the uncoated portion to cut a part of the uncoated portion forming an electrode tab;
- and
- collecting the electrode sheet with the electrode tab,
- wherein the drum includes:
- a first drum in contact with the coated portion of the supplied electrode sheet;
- a second drum located at a side of the first drum, the second drum being in contact with at least a part of the uncoated portion;
- and
- a pattern jig removably mounted to the second drum, the pattern jig having an opening configured to allow the laser beam to pass therethrough.
