Abstract
Provided is an apparatus for manufacturing a battery cell. The apparatus for manufacturing a battery cell includes a plurality of rollers pressing at least a portion of an exterior material of the battery cell in a first direction toward the battery cell, wherein the plurality of rollers are movable in the direction toward the battery cell and include a first roller and a second roller having inclined surfaces inclined at different angles.
Claims9
An apparatus for manufacturing a battery cell for processing a sealing portion of an exterior material of the battery cell, the apparatus comprising:
- at least one roller unit including an upper roller and a lower roller arranged to face each other,
- wherein a rotation shaft of the upper roller and a rotation shaft of the lower roller are respectively perpendicular to a moving direction of the battery cell, and
- a roller gap which is a space through which at least a portion of the sealing portion of the exterior material passes formed between the upper roller and the lower roller,
- wherein an axis of rotation of the upper roller is inclined with respect to an axis of rotation of the lower roller.
An apparatus for securing a sealing portion of a battery cell adjacent to a body portion of the battery cell, the apparatus comprising:
- a plurality of pairs of press rollers arranged in a moving direction of the battery cell,
- wherein each pair of the press rollers having a gap,
- wherein the first pair of the press rollers has a gap to receive the sealing portion of the battery cell and the gap of each subsequent pair of rollers is gradually reduced for applying a gradually increasing pressure on the sealing portion for urging the sealing portion closer to the body portion of the battery cell,
- wherein each pair of the press rollers includes an upper roller and a lower roller arranged to face each other, and
- wherein an axis of rotation of the upper roller is inclined with respect to an axis of rotation of the lower roller.
