1. A lamination apparatus for a secondary battery, the lamination apparatus comprising:
an electrode transfer part configured to transfer at least one or more electrodes;
a separator transfer part configured to transfer at least one or more separators;
a combination part configured to combine and transfer the electrodes and the separators that are to be alternately disposed; and
a position correction part configured to correct a position of an electrode among combined electrodes and the separators to align the position of the electrode with a set position of a separator among the combined electrodes and separators,
wherein the position correction part comprises a pair of correction members, which are respectively provided on opposite sides of the combined electrodes and separators,
wherein the pair of correction members comprise a belt of which a portion facing the combined electrodes and separators rotates in the same direction as a transfer direction of the combined electrodes and separators, and
wherein the pair of correction members further comprise:
a driving roller coupled to a front end of the belt into which the combined electrodes and separators is introduced, the driving roller being configured to rotate the belt;
two or more driven rollers coupled to a rear end of the belt from which the combined electrodes and separators is withdrawn, the two or more driven rollers being configured to be rotated by the belt,
wherein the position correction part further comprises a moving member that allows the pair of correction members to move toward the electrode so as to press the left or right surface of the uppermost electrode or allows each of the pair of correction members to return to its original position so as not to press the electrode, and
wherein the moving member moves the pair of correction members toward the electrode from opposite sides in a direction perpendicular to the transfer direction of the combined electrodes and separators.
