Apparatus for manufacturing electrode plate

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.
