Abstract
An unwinding device for manufacturing a secondary battery includes an unwinder, a transfer unit, and a correction unit having a rotation shaft. The unwinder is configured for unwinding a coating substrate wound in a roll shape by rotating it around the rotation shaft. The transfer unit includes a first transfer roll disposed closest to the unwinder. The correction unit is configured for correcting (i.e., moving) the position of the rotation shaft with respect to the first transfer roll.
Claims13
An unwinding device for manufacturing a secondary battery using a coating substrate wound on an electrode reel, the unwinding device comprising:
- a correction unit having a rotation shaft;
- an unwinder configured to unwind the coating substrate wound on the electrode reel in a roll shape by rotating the electrode reel around the rotation shaft;
- and
- a transfer unit comprising a first transfer roll spaced from the unwinder,
- wherein the correction unit is configured to adjust the position of the rotation shaft with respect to the first transfer roll.
