Claim 0:
1. An apparatus for manufacturing an electrode plate, comprising:
an unwinder on which an electrode reel is installed;
a meandering corrector correcting meandering of an electrode sheet unwound from the electrode reel;
a press puncher disposed at a rear end of the meandering corrector;
a cutter disposed at a rear end of the press puncher;
a detector configured to acquire an image of the electrode sheet, and the detector disposed between the press puncher and the cutter; and
a controller connected to the detector and the meandering corrector,
wherein the electrode reel comprises the electrode sheet,
wherein, as an uncoated portion included in the electrode sheet is removed at a regular interval by the press puncher, a portion of a region coated with an active material is removed, together with the uncoated portion, and wherein the active material protrudes toward the uncoated portion of the electrode sheet,
wherein the controller is configured to use a height of the active material protruding toward the uncoated portion of the electrode sheet, in the image acquired from the detector, to determine whether the electrode sheet meanders, and
wherein the controller is configured to select at least four regions in the image acquired from the detector to sense the height of the active material.
