Medical needle tube positioning structure and medical needle automatic assembly equipment

Abstract

The invention relates to the technical field of medical needle assembling, and discloses a medical needle tube positioning structure. The structure comprises a first positioning block and a second positioning block; the first positioning block forms a positioning slope matched with a blade face of a medical needle, and the second positioning block forms a positioning straight surface matched with the plane of the medical needle; the positioning slope and the positioning straight surface are oppositely arranged to form a positioning area allowing a medical needle tube to be inserted. A gap containing a needle point of the medical needle tube is formed between the first positioning block and the second positioning block. According to the medical needle tube positioning structure, the needle point penetrates the positioning area and is contained in the gap; meanwhile, the positioning slope plays a role in guiding the blade face and is matched with the blade face in an abutting-joint mode; the positioning straight face can limit radial movement of the medical needle tube, and the medical needle tube only can axially move; accurate positioning of the medical needle tube can be achieved; automation assembling of the medical needle can be achieved by utilizing accurate positioning of the medical needle tube; and the assembled medical needle is good in consistency, and waste is avoided.

Description

technical field [0001] The invention relates to the technical field of medical needle assembly, in particular to a medical needle tube positioning structure and medical needle automatic assembly equipment comprising the medical needle tube positioning structure. Background technique [0002] In the medical equipment industry, the application of medical needles is quite common. The medical needle tube is the main component of the medical needle, which is connected to the front end of the needle barrel. [0003] At present, in the assembly of commonly used disposable medical needles, manual assembly still accounts for a considerable proportion, that is, the medical needle tube and the syringe are assembled together by manual operation; some companies use semi-automatic or automatic equipment to Assembling medical needles, however, the problem of positioning medical needle tubes has not been completely resolved. In this way, if the length and blade angle of medical needle tubes...
