Full-automatic test tube cap tightening instrument

Abstract

The invention relates to a full-automatic test tube cap tightening instrument. The full-automatic test tube cap tightening instrument comprises a movable guide rail; the head end of the movable guide rail is connected with a feed frame module; further, the feed frame module is provided with a feed frame table plate positioned on the same one plane with the movable guide rail; a cap tightening module is arranged at the middle end of the movable guide rail; further, the cap tightening module is at least provided with a cap tightening cylinder; a discharge frame module is arranged at the tail end of the movable guide rail; the discharge frame module includes a pushing mechanism; and further, the discharge frame module is provided with a discharge frame table plate positioned on the same one plane with the movable guide rail. The cap tightening module includes test tube clamping blocks arranged on two sides of the movable guide rail; the test tube clamping blocks are connected with clamping inserts; further, accommodating semicircular holes are formed in the inner sides of the clamping inserts; and concave convex grooves are formed in the inner walls of the accommodating semicircular holes. The full-automatic test tube cap tightening instrument can overally realize automatic test tube cap tightening, is high in working efficiency and excellent in cap tightening effect, reduces the working intensity of related staff, and meanwhile, can prevent the sample pollution caused by manual cap tightening.

Description

technical field [0001] The invention relates to a fully automatic test tube cap unscrewing instrument, which belongs to the technical field of test tube cap unscrewing. Background technique [0002] At present, in medical clinical examination, it is necessary to use vacuum test tubes to collect blood as test samples. After blood is collected in vacuum test tubes, there is a certain negative pressure in the vacuum test tubes, and the connection between the test tube cover and the test tube wall is relatively tight. It takes a lot of force to pull off the test tube cap. There is a kind of test tube for retaining samples. The test tube cap of this kind of test tube is tightly combined with the test tube. There are ear handles on both sides of the test tube cap. The purpose of removing the cap is achieved by rotating the ear handle. finger pain, due to internal vibration of the test tube during the process of opening the test tube cover, causing sample dispersion and affecting ...

AI Technical Summary

Problems solved by technology

The device adopts a combination of gears to remove the cap. There are many gear structures, and the test tube is placed in the test tube box. The fixing effect is poor, and it is difficult to ensure the cap removal effect of the test tube. Vacuum test tubes are not suitable for taking off the caps of the sample test tubes with ear handles
