Abstract

Disclosed in the present application are a winding needle (10), a winding device (1000) and a battery processing system. The winding needle comprises: an inner needle (11); at least two outer needles (12), which surround the inner needle along the circumference of the inner needle, and are movably arranged on the circumferential side of the inner needle in the radial direction of the inner needle; and a first structural member (13), which abuts against the outer needles, and can move relative to the outer needles in the axial direction of the inner needle to push the outer needles away from the inner needle in the radial direction of the inner needle. In the winding needle of the present application, the first structural member pushes the outer needles away from the inner needle in the radial direction of the inner needle, thereby achieving the effect of expanding the outer diameter of the winding needle; and the first structural member can be disengaged from the outer needles, and then an electrode assembly can apply pressure to the winding needle to enable the outer needles to move close to the inner needle in the radial direction of the inner needle, thereby achieving the effect of reducing the outer diameter of the winding needle. In this way, the outer diameter of the winding needle can be increased or decreased, so that the outer diameter of the winding needle can be adjusted during the winding process of the electrode assembly, thereby reducing the tab misalignment.
