Abstract
An apparatus for winding an electrode assembly includes a winding unit including a motor unit to supply a winding power; a cam unit connected to the motor unit and configured to rotate when the motor unit supplies the winding power; a power transmission unit connected to the cam unit; and a mandrel connected to the power transmission unit and configured to receive a first electrode plate, a second electrode plate, and a separator wound thereon.
Claims10
An apparatus for winding an electrode assembly, the apparatus comprising a winding unit comprising:
- a motor unit to supply a winding power;
- a cam unit connected to the motor unit and configured to rotate when the motor unit supplies the winding power;
- a power transmission unit connected to the cam unit;
- and
- a plate-shaped mandrel connected to the power transmission unit and configured to receive a first electrode plate, a second electrode plate, and a separator wound thereon,
- wherein a first rotational speed provided to the plate-shaped mandrel by the cam unit and the power transmission unit when a lateral surface of the plate-shaped mandrel is positioned to be parallel with a supplying direction in which a base member including the first electrode plate, the second electrode plate, and the separator is supplied to the plate-shaped mandrel is greater than a second rotational speed provided to the plate-shaped mandrel by the cam unit and the power transmission unit when the lateral surface of the plate-shaped mandrel is positioned to be perpendicular to the supplying direction.
