A sheet connection device for a secondary battery comprising:
- a first main roller around which a first sheet is wound;
- a second main roller around which a second sheet is wound;
- a first correction roller configured to wind at least a portion of the first sheet moving from the first main roller;
- a first sensor configured to detect a position of the first sheet moving from the first main roller to the first correction roller;
- a controller configured to adjust the position of the first sheet in a sheet width direction while the at least the portion of the first sheet is being wound around the first correction roller;
- and
- a connection unit configured to connect the repositioned first sheet with the second sheet.
A sheet connection method comprising:
- performing a test run comprising winding a first sheet waiting for a subsequent process moving from a first main roller around a correction roller;
- detecting, by a sensor, a position of the first sheet moving from the first main roller to the correction roller;
- adjusting, by a controller, the position of the first sheet in a sheet width direction while at least a portion of the first sheet is being wound around the correction roller;
- and
- connecting, by a connection unit, the first sheet whose position is adjusted with a second sheet being supplied from a second main roller to the subsequent process.
