Abstract
An electrode assembly manufacturing apparatus for fabricating a stack includes a stack table, gripper, and first press unit. The stack includes a first electrode, a second electrode, and a section of a separator between the first and the second electrodes. The stack table is configured for supporting the stack. The gripper is configured for fixing the stack. The first press unit is configured for heating and compressing the stack fixed by the gripper.
Claims14
An electrode assembly manufacturing apparatus for fabricating a stack comprising a first electrode, a second electrode, and a second electrode section of a separator between the first and the second electrodes, comprising:
- a stack table configured for supporting the stack;
- a gripper configured for fixing the stack;
- and
- a first press unit configured for heating and compressing the stack fixed by the gripper, the first press unit including a pair of pressing blocks configured for compressing opposing surfaces of the stack, each of the pair of pressing blocks of the first press unit including a gripper groove having a shape corresponding to a shape of the gripper, the gripper groove having a depth greater than a height of the gripper, so that the first press unit is configured to press only a surface of the stack on which the gripper is not positioned.
An electrode assembly manufacturing apparatus for fabricating a stack comprising a first electrode, a second electrode, a first electrode section of a separator underlying the first electrode, and a second electrode section of the separator between the first and the second electrodes, comprising:
- a stack table configured for supporting the stack;
- a separator supply unit configured for supplying the separator to the stack table;
- a first electrode supply unit configured for stacking the first electrode on a first electrode section of the separator supported by the stack table;
- a second electrode supply unit configured for stacking the second electrode on a second electrode section of the separator when the second electrode is supported by the stack table;
- a gripper configured for fixing the stack;
- a first press unit configured for heating and compressing the stack fixed by the gripper, the first press unit including a pair of pressing blocks configured for compressing opposing surfaces of the stack, each of the pair of pressing blocks of the first press unit including a gripper groove having a shape corresponding to a shape of the gripper, the gripper groove having a depth greater than a height of the gripper, so that the first press unit is configured to press only a surface of the stack on which the gripper is not positioned;
- and
- a second press unit configured for heating and compressing the stack.
