The present invention provides a winding device for winding a lithium battery cell. The winding device comprises a rotating large disk, a plurality of winding needles and an auxiliary mechanism; the auxiliary mechanism comprises a swinging roller, a third traverse roller located at the outer side of the swinging roller, a fourth traverse roller located at the lower portion of the third traverse roller, a motor configured to drive the swing of the swinging roller, a motor configured to drive the lateral displacement of the third traverse roller and the fourth traverse roller, and a correction mechanism located at the upper portion of the third traverse roller; the swinging roller is driven by the motor and can be located at a first position close to the third traverse roller and a second position far away from the third traverse roller; the correction mechanism comprises a first correction roller and a second correction roller, and the first correction roller is driven by a cylinder tobe close to or far away from the second correction roller; and the second correction roller can be fixed with a closed first correction lock, and is driven by the motor to correct pole pieces clampedby the first correction roller and the second correction roller. The precision is high, the stability is good, and the processing efficiency is greatly improved.
