1. A variable-diameter adsorption winding needle mechanism, comprising a winding needle assembly, a first adsorption winding needle, a second adsorption winding needle and a pin assembly, wherein the winding needle assembly is configured to be connected with a winding head and rotated under driving of the winding head, the first adsorption winding needle and the second adsorption winding needle are arranged oppositely and configured to be spliced to form a winding needle head for winding a material tape, an accommodating through hole running through the winding needle head at center thereof is provided at a splicing position between the first adsorption winding needle and the second adsorption winding needle, the winding needle assembly is arranged as partially penetrating through the accommodating through hole and extends out from one end of the winding needle head, the pin assembly is arranged at the other end of the winding needle head, is arranged opposite to the accommodating through hole, and is configured to be in detachable transmission connection with the winding needle assembly, a plurality of adsorption holes configured for adsorbing a head of the material tape are provided on outer peripheral surfaces of the first adsorption winding needle and the second adsorption winding needle, the winding needle assembly is further configured to drive the first adsorption winding needle and the second adsorption winding needle to move away or close to each other under driving of the pin assembly, so as to increase or decrease a winding diameter of the winding needle head.
