description The utility model discloses a winding needle, a pole piece winding device and battery manufacturing equipment. The winding needle comprises an inner needle assembly and an outer needle assembly. The inner needle assembly is used for clamping a pole piece, at least part of the outer needle assembly is arranged on the periphery of the inner needle assembly in a sleeving mode, and the outer needle assembly is used for being matched with the inner needle assembly and rotating around the axial direction of the inner needle assembly so that the pole piece can be wound into an electrode assembly. Wherein the outer needle assembly can move in the axial direction of the inner needle assembly and draw out the electrode assembly, so that a gap is formed between the inner needle assembly and the electrode assembly. The outer needle assembly can slide relative to the inner needle assembly, a gap can be formed between the formed electrode assembly and the inner needle assembly, subsequent secondary winding of the inner nee
