Pouch-shaped battery sealing apparatus including stopper and pouch-shaped battery sealing method using the same

A pouch-shaped battery sealing apparatus comprising an upper sealing block, a lower sealing block, and a stopper unit configured to limit a minimum distance between the upper sealing block and the lower sealing block, wherein the stopper unit comprises:

• a first stopper disposed at a first side of the upper sealing block and configured to contact the upper sealing block in order to prevent downward movement of the upper sealing block beyond a predetermined limit;
• a support shaft disposed at the first side of the upper sealing block, the support shaft being translationally coupled to the first stopper, the support shaft having a fixed position relative to the lower sealing block;
• a measurement portion configured to measure a movement change of the first stopper relative to the lower sealing block;
• and
• a height adjustment portion configured to adjust a translational position at which the first stopper is disposed relative to the lower sealing block, the height adjustment portion being threadedly coupled to a threaded opening formed in the first stopper, the height adjustment portion being configured such that rotation thereof causes the first stopper to move along the support shaft.
