Abstract
A winding device includes a pair of outer pins oppositely arranged in a first direction with a periphery for an electrode assembly to wind around, adjusting members configured to reciprocate in a second direction perpendicular to the first direction to drive the pair of outer pins to move away from or close to each other to increase or reduce a distance between the pair of outer pins, a pair of inner pins arranged oppositely in the first direction between the pair of outer pins and configured to move independent of the adjusting members to clamp or release the electrode assembly, and an elastic returning member configured to apply an elastic force in the first direction to at least one of the pair of inner pins such that the pair of inner pins have a tendency to be close to each other.
