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;
an image detector configured to acquire an image of the electrode sheet, and the image detector disposed between the press puncher and the cutter;
a controller connected to the image detector and the meandering corrector, and
a first dancer roll disposed at a front end of the meandering corrector, and a second dancer roll disposed between the meandering corrector and the press puncher,
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, and
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 image detector, to determine whether the electrode sheet meanders.
