Reference point marking apparatus and roll map generating apparatus

A roll map generation apparatus comprising:

• a position measuring device configured to obtain coordinate data pertaining to a position of a pattern electrode in a longitudinal direction of the pattern electrode according to an amount of rotation of an unwinder or a rewinder when the pattern electrode is moved in a roll-to-roll state between the unwinder and the rewinder, and represent the coordinate data using first pattern number unit data corresponding to coated portions, wherein the coated portions and uncoated portions are repeatedly arranged on the pattern electrode in the longitudinal direction;
• a marking machine configured to mark reference points on the pattern electrode at predetermined intervals in the longitudinal direction of the pattern electrode in connection with the position measuring device;
• and
• a roll map generator configured to obtain the coordinate data related to the position of the pattern electrode in the longitudinal direction, the first pattern number unit data corresponding to the coated portions, and second pattern number unit data corresponding to the reference points marked using the position measuring device and the marking machine, and generate a roll map by displaying at least the first and/or second pattern number unit data on a roll map that simulates an electrode moving in the roll-to-roll state,
• wherein the pattern electrode comprises a plurality of reserved electrode lane parts to be slit into a plurality of electrode lanes in the longitudinal direction of the pattern electrode in a subsequent process,
• the marking machine comprises a moving marking machine configured to mark the reference points on uncoated portions of the plurality of reserved electrode lane parts arranged in a width direction of the pattern electrode while moving in the width direction, and
• the roll map generator generates a first roll map for the pattern electrode and a second roll map for each of the plurality of reserved electrode lane parts based, at least in part, on the second pattern number unit data marked by the moving marking machine.

A roll map which is a simulated electrode that simulates a pattern electrode in which coated portions and non-coated portions are repeatedly arranged in a longitudinal direction, the roll map comprises at least one of:

• 1) coordinate data about a position of the pattern electrode in the longitudinal direction;
• 2) pattern number data about the position of the pattern electrode in the longitudinal direction;
• 3) a plurality of reference points marked on uncoated portions between the coated portions at intervals of predetermined pattern numbers;
• 4) coordinate data and/or pattern number data of the reference points;
• and
• 5) a defect marking part indicating defects of the pattern electrode or coordinate data and/or pattern number data of the defect marking part.
