Roll map generating device for merge-wound electrode

An apparatus for generating a roll map of a merge-wound electrode, the apparatus comprising:

• a position measurement device configured to acquire, when the merged-wound electrode moves in a roll-to-roll state between an unwinder and a rewinder, coordinate value data for a longitudinal position at the merged-wound electrode according to an amount of rotation of the rewinder;
• an input device configured to input, when two or more electrodes to be merged that are each marked with a plurality of reference points at one or more intervals are connected to be merged and wound into the merge-wound electrode, an input signal indicating a start of merge-winding or an end of merge-winding;
• a seam detector configured to detect a seam, which is a connection portion of two electrodes merged in the merge-wound electrode, and to acquire electrode coordinate values of the seam from the position measurement device;
• a reference point detector configured to detect a plurality of reference points of the merge-wound electrode corresponding to the plurality of reference points of the two or more electrodes to be merged and to acquire electrode coordinate values of the plurality of reference points of the merge-wound electrode from the position measurement device;
• and
• a roll map generator configured to generate a roll map for simulating the merge-wound electrode moving in a roll-to-roll state based on the input signal of the input device, and to display the longitudinal coordinate values of the electrode, the electrode coordinate values of the seam, and the electrode coordinate values of the plurality of reference points of the merge-wound electrode on the roll map in conjunction with the position measurement device, the seam detector, and the reference point detector.
