Abstract
A folding processing apparatus for a battery cell includes a first guide member defining a first folding line on a first surface of a sealing portion of a battery cell, a second guide member defining a second folding line on the first surface of the sealing portion, a first bending member defining the first folding line on a second surface of the sealing portion and bending the sealing portion along the second folding line, and a second bending member bending the sealing portion by 180 degrees along the first folding line.
Claims18
A folding processing apparatus for a battery cell, the folding processing apparatus comprising:
- a first guide member defining a first folding line on a first surface of a sealing portion of a battery cell;
- a second guide member defining a second folding line on the first surface of the sealing portion;
- a first bending member defining the first folding line on a second surface of the sealing portion and bending the sealing portion along the second folding line;
- and
- a second bending member bending the sealing portion by 180 degrees along the first folding line.
A folding processing apparatus for a battery cell, the folding processing apparatus comprising:
- a first guide member disposed to be linearly and rotatably movable and pressing a first folding line of a sealing portion of a battery cell on a first surface of the sealing portion;
- a first bending member disposed on a second surface of the sealing portion and supporting the sealing portion;
- and
- a second bending member firstly bending the sealing portion, while moving in a first direction, a thickness direction of the battery cell, and secondly bending the sealing portion, while moving in a second direction, a surface direction of the battery cell,
- wherein the first guide member supports the first folding line, while the second bending member moves in the first direction, and
- when the second bending member moves in the second direction, the first guide member rotates to be separated from the sealing portion.
A battery cell manufacturing method comprising:
- a first operation in which a first guide member presses a first surface of a sealing portion of a battery cell and a first bending member presses a second surface of the sealing portion to define a first folding line;
- a first bending operation in which a second bending member bends the sealing portion along the first folding line, while moving in a first direction, a thickness direction of the battery cell;
- a second bending operation in which the second bending member bends the sealing portion along the first folding line, while moving in a second direction, a surface direction of the battery cell;
- and
- a third bending operation in which the first bending member bends the sealing portion, while moving in the first direction along a second folding line defined by a second guide member.
