Abstract
An electrode rolling apparatus according to an embodiment of the present disclosure includes a sensing unit positioned above an electrode for a secondary battery being transferred along a lengthwise direction to measure a distance to the electrode for each location along a widthwise direction of the electrode, a control unit which identifies a location of a non-coated portion formed on the electrode using information associated with the distance between the sensing unit and the electrode measured through the sensing unit, and outputs a control signal to heat a region in which the identified non-coated portion is formed, a heating unit positioned above the electrode to selectively heat only the region in which the non-coated portion is formed according to the control signal of the control unit, and a rolling unit which rolls the electrode having the selectively heated region in which the non-coated portion is formed.
