  • Winder for electrode assembly of rechargeable battery and electrode assembly manufacturing method using the same
    Patent number: 9293782
    Abstract: An exemplary embodiment provides a winder for an electrode assembly of a rechargeable battery capable of improving productivity by shortening a winding cycle. A winder for an electrode assembly of a rechargeable battery according to an exemplary embodiment includes: a nip roll catching and feeding a positive plate and a negative plate, and a separator; a rotor disposed below the nip roll to rotate; and a plurality of winding cores arranged in the rotor at a regular interval in a rotation direction of the rotor to rotate and move forward or backward from the rotor, wherein the center of the nip roll, the center of any one winding core among the plurality of winding cores, and one surface of an electrode assembly of another winding core which is winding-completed form a straight line.
