Abstract
The present invention relates to a pouch-shaped battery case sealing apparatus capable of adjusting a direction in which an upper sealing block configured to press a laminate sheet applies pressure to the laminate sheet during a process of applying heat and pressure to an outer periphery of a battery case made of the laminate sheet to seal the outer periphery of the battery case when a pouch-shaped battery is manufactured and a pouch-shaped secondary battery sealing method using the same.
Claims10
A pouch-shaped battery case sealing apparatus, comprising:
- an upper sealing block and a lower sealing block together configured to seal a surface of a pouch-shaped battery case,
- wherein the surface of the pouch-shaped battery case defines an X-Y plane extending along both an X-axis and a Y-axis,
- the upper sealing block and the lower sealing block each configured to be disposed parallel to the Y-axis in an initial orientation,
- the upper sealing block is pivotably coupled to a fixing shaft configured to move upwards and downwards along a Z-axis perpendicular to the X-Y plane, and
- the upper sealing block and the fixing shaft are pivotably coupled to each other via a hip joint type coupling unit
- wherein the coupling unit is configured to perform spin motion about the X-axis and/or spin motion about the Y-axis.
