1. A winding device, comprising:
a pair of outer pins, wherein the pair of outer pins are oppositely arranged in a first direction, and a periphery of the pair of outer pins is used for an electrode assembly to be wound around;
adjusting members, wherein the adjusting members are configured to reciprocate in a second 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, and the second direction is perpendicular to the first direction;
a pair of inner pins, wherein the pair of inner pins are arranged between the pair of outer pins, the pair of inner pins are oppositely arranged in the first direction, and the pair of inner pins are configured to move independent of the adjusting members, to clamp or release the electrode assembly;
an elastic returning member, wherein the elastic returning member is 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;
a base, wherein the pair of outer pins and the pair of inner pins are mounted on the base; and
a pair of supporting frames, wherein the pair of supporting frames are oppositely arranged in the first direction and are fixed on the base;
wherein the pair of inner pins are located between the pair of supporting frames, the adjusting members are mounted on the supporting frames, the pair of outer pins correspond to the pair of supporting frames one by one, and each of the pair of outer pins is arranged outside a corresponding supporting frame of the pair of supporting frames and movably connected to the corresponding supporting frame in the first direction.
