[0043] An injection needle is a medical device used to inject drugs, liquids, etc. into the body. In the medical field, injection needles have a wide range of applications, such as vaccination, infusion, and injecting drugs to treat diseases. An injection needle usually consists of a needle tip and a needle wing. The needle tip is the sharp part used to pierce the skin and tissue to achieve drug injection or body fluid extraction. The needle wing is a structure near the needle tip, which is used to facilitate the operation of medical staff and fix the needle tip. When producing an injection needle, the needle wing is inserted on the production equipment, and then the needle tip is precisely assembled with the needle wing through an injection needle assembly device, and other components may be added, such as a needle cap, a syringe piston, etc. Currently, the relatively common needle wing feeding process mainly relies on manual operation. Since the needle wing is a silicone product and is relatively soft after molding and prone to deformation, it is difficult for workers to manually insert the needle wing into the production equipment, wasting a large amount of labor and having low efficiency.
