An automatic continuous filling system for blood collection tubes

Abstract

The invention discloses an automatic and continuous filling system of blood sampling test tubes and relates to the technical field of test tube filling equipment. The problems that during filling, test tubes are easily abraded, and defective products of the test tubes cannot be automatically detected are solved. A machine body, vibration disks, guide pipe channels, a roller bed, a collecting box,a vibration tray, a mold frame, a tube installing mechanism, a transferring mechanism and a conveying mechanism are included; and a linear array camera, pneumatic fingers and a vacuum suction nozzle are arranged at the position, over the roller bed, on the machine body, and a push rod is fixed to the pneumatic fingers. According to the automatic and continuous filling system of the blood samplingtest tubes, the test tubes are automatically laid flatly through the roller bed, the conveyed test tubes are subjected to line scanning image comparison through the linear array camera, defective products of the test tubes are positioned, and are pushed out under the joint effects of the pneumatic fingers and the vacuum suction nozzle, and the quality of the filled test tubes is guaranteed; and due to the manner of roller bed guide pipes, the test tubes are arranged smoothly and orderly, the tube clamping phenomenon is reduced, and damage to the test tubes is further reduced.

Description

technical field [0001] The invention relates to the technical field of test tube filling equipment, in particular to an automatic continuous filling system for blood collection tubes. Background technique [0002] The blood collection tube is a disposable negative pressure vacuum glass tube that can realize quantitative blood collection. The filling of the blood collection tube is a very critical step in the production process of the blood collection tube. Among the tools, some companies usually fill blood collection tubes by manual filling, which is slow and inefficient. Some companies also use automated assembly lines to fill blood collection tubes, which is faster and more efficient. However, due to the change in the body weight of the blood collection tube and the uncertainty of the length of the stroke when the test tube is free falling, it is easy to cause the blood collection tube to get stuck, resulting in the stoppage of the assembly line, which affects the overall ...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: the test tubes (i.e. blood collection tubes) are driven by the test tube sheave to drop directly onto the conveying rollers. Since the test tubes themselves have a certain gravity, the interaction between the falling on the conveying rollers and the conveying rollers The force is easy to cause wear and scratches on the test tubes, forming defective test tubes, and the above-mentioned production line is a fully automatic mechanism, except for the way of human eye observation and manual retrieval, it is impossible to automatically detect the defective test tubes. Therefore, the automatic detection of test tubes The filling method still needs to be improved
