Abstract
A sealing apparatus includes an upper sealing block and a lower sealing block, a sealing gap measuring unit coupled to the upper sealing block, and a reference block coupled to the lower sealing block to face the sealing gap measuring unit. The sealing gap measuring unit includes a probe housing coupled to the upper sealing block, a probe having both end portions protruding from an upper portion and a lower portion of the probe housing and installed to pass through the probe housing to move relative to the probe housing, and a detection unit to detect a height or a change in height of the probe protruding from the upper portion of the probe housing.
Claims15
A sealing apparatus comprising:
- an upper sealing block and a lower sealing block configured to receive a battery cell therebetween and move relative to each other so as to seal a sealing target portion of the battery cell, wherein the upper sealing block and the lower sealing block are spaced apart from each other in a vertical direction;
- a sealing gap measuring unit coupled to the upper sealing block;
- and
- a reference block coupled to the lower sealing block and facing the sealing gap measuring unit,
- wherein the sealing gap measuring unit includes:
- a probe housing coupled to the upper sealing block;
- a probe having each of both end portions protruding from an upper portion and a lower portion of the probe housing, respectively, the probe being configured to pass through the probe housing so as to move relative to the probe housing;
- and
- a detection unit configured to detect a height of the probe or a change in the height of the probe protruding from the upper portion of the probe housing,
- wherein, when the upper sealing block and the lower sealing block seal the battery cell by pressing while moving relative to each other, a sealing gap defined between the upper and lower sealing blocks is configured to be measured based on a height increase of the probe detected by the detection unit as a lower end portion of the probe is moved upward by being pressed by the reference block.
