System for determining cause of electrode connection and roll map generation system using same

A roll map generation system comprising:

• a position measuring instrument configured to, when an electrode moves between an unwinder and a rewinder in a roll-to-roll state, acquire coordinate value data based on a longitudinal position of the electrode determined according to a rotation amount of the rewinder;
• a plurality of signal generators, wherein a signal generator associated with a cause event that results in an electrode connection at the electrode, is configured to generate a connection advance notice signal corresponding to the electrode connection;
• a seam detector configured to detect a seam attached onto the electrode after the connection advance notice signal is generated;
• a determination unit configured to, when the seam is detected within a predetermined distance from a first coordinate value of the electrode after the connection advance notice signal is generated, determine a cause of the cause event of the electrode connection by the seam among a plurality of causes based on the connection advance notice signal generated by the signal generator associated with the cause event;
• and
• a roll map generation unit configured to generate a roll map comprises a simulated electrode in the roll-to-roll state,
• wherein the roll map comprises predetermined coordinates of the longitudinal position of the electrode and a position of the seam, and
• wherein the roll map generation unit is configured to display the roll map and the connection cause of the electrode connection at the position of the seam.
