1. A tape attachment apparatus comprising:
a tape;
a battery cell;
a stage on which the battery cell is seated such that a portion of the battery cell to which the tape is to be attached faces the tape;
a tape feeder configured to feed the tape in an X-axis direction to the battery cell;
a tape pressing unit configured to press the tape to the battery cell; and
a tape cutting unit configured to cut the tape fed from the tape feeder while the tape is pressed to the battery cell,
wherein the tape pressing unit comprises:
a pressing member configured to attach the tape to the battery cell by pressing a leading end of the tape fed to the stage to the battery cell;
a pressing member support configured to support the pressing member; and
a pressing member movement module provided on the pressing member support and connected to the pressing member so as to move the pressing member in a Z-axis direction,
wherein the tape cutting unit comprises:
a cutter having a cutting blade, the cutting blade with a larger width than a width of the tape, and the cutter being disposed such that a first portion of the cutting blade is configured to contact the tape and to cut the tape during first cutting operations, wherein a second portion of the cutting blade does not contact the tape during the first cutting operations;
a cutter elevation module comprising a motor, the cutter elevation module configured to move the cutter in the Z-axis direction, the Z-axis direction being perpendicular to a surface of the tape; and
a cutter movement module comprising a linear moving mechanism, the cutter movement module configured to move the cutter in a Y-axis direction being perpendicular to both the X-axis direction and the Z-axis direction,
wherein, after the first cutting operations, the cutter movement module is configured to move the cutter to be disposed such that the second portion of the cutting blade is configured to contact the tape and to cut the tape during second cutting operations,
wherein the first portion of the cutting blade does not contact the tape during the second cutting operations, and
wherein the first portion is different than the second portion.
