Abstract
The present invention relates an apparatus for sealing a secondary battery, which seals a pouch. The apparatus for sealing the secondary battery comprises: a support block configured to support a bottom surface of one-side sealing part of the pouch; a sealing member comprising a sealing roller that moves in a longitudinal direction of the one-side sealing part in a state of pressing a top surface of the one-side sealing part supported on the support block to seal the one-side sealing part supported on the support block; and a straightening member configured to flatten a surface of the one-side sealing part on which the sealing roller passes.
Claims15
An apparatus for sealing a pouch of a secondary battery, the apparatus comprising:
- a support block configured to support a bottom surface of a one-side sealing part of the pouch;
- a sealing member comprising a sealing roller that is configured to move in a longitudinal direction of the one-side sealing part in a state of pressing a top surface of the one-side sealing part supported on the support block to seal the one-side sealing part supported on the support block;
- and
- a straightening member configured to flatten the top surface of the one-side sealing part on which the sealing roller is configured to press.
A method for sealing a pouch of a secondary battery in which an electrode assembly is accommodated, the method comprising:
- a support block disposition step of disposing a support block on a bottom surface of a one-side sealing part of the pouch, wherein the support block is supported in a longitudinal direction of the one-side sealing part;
- a sealing roller disposition step of disposing a sealing roller on a first end of a top surface of the one-side sealing part supported by the support block;
- a straightening block disposition step of disposing a pair of straightening blocks on opposite respective sides of the support block, wherein the straightening block is supported in the longitudinal direction of the one-side sealing part;
- a straightening roller disposition step of disposing a straightening roller on the first end of the top surface of the one-side sealing part supported on the straightening block, wherein the straightening roller is pressing the one-side sealing part;
- a straightening roller moving step moving the straightening roller from the first end to the second end of the one-side sealing part thereby flattening a portion of the top surface of the one-side sealing part that is disposed between the straightening rollers;
- and
- a sealing roller moving step of moving the sealing roller from the first end to the second end of the one-side sealing part thereby sealing the one-side sealing part supported on the support block, wherein the one-side sealing part supported on the support block is sealed while being flattened by the straightening roller.
