Battery label alignment device and method

A battery label attachment apparatus for attaching a label to a battery, comprising:

• a servo robot on which the label is placed, the servo robot configured to move the label to a corresponding position of the battery, the label being attachable to the battery at the corresponding position of the battery;
• an alignment check part configured to check whether an alignment state of the label is normal or defective, the alignment check part including:
• a first sensor disposed to be spaced apart by a preset distance to the left with respect to the servo robot;
• a second sensor disposed to be spaced apart a preset distance to the right with respect to the servo robot, the first sensor and the second sensor are disposed side by side on a straight line perpendicular to a moving direction of the servo robot;
• and
• an alignment determining part configured to determine, according to a combination of signals detected by the first and second sensors, whether the alignment state is normal or defective;
• and
• a label aligning part configured to align the label when the alignment state determined by the alignment check part is defective,
• wherein the servo robot is displaceable relative to the first and second sensors, and
• wherein the servo robot, the first sensor, and the second sensor are disposed below the label.
