Abstract
An electrode winding apparatus and method of detecting displacement between a strip-shaped electrode and a strip-shaped separator when stacking and winding the strip-shaped electrode and the strip-shaped separator is described. A winding shaft is configured to wind the strip-shaped electrode and the strip-shaped separator, and a guide member is configured to stack the strip-shaped electrode and the strip-shaped separator before the strip-shaped electrode and the strip-shaped separator are wound around the winding shaft. An imaging device is disposed so as to photograph a portion in which the strip-shaped electrode and the strip-shaped separator are stacked between the guide member and the winding shaft from a side on which the strip-shaped separator is stacked. The imaging device is configured to photograph the strip-shaped separator and the strip-shaped electrode through the strip-shaped separator.
