During the test, the vacuum blood collection tubes need to be opened for the next step of automatic sampling and testing. The tested samples will be stored for a certain period of time for subsequent re-examination. In order to ensure the validity of the samples, the vacuum blood collection tubes need to be covered and stored.

[0003] At present, the medical test automation line uses aluminum foil hot-melt to seal vacuum blood collection tubes, which may not be tightly sealed. It can only seal plastic materials, but not glass vacuum blood collection tubes. Special film removal equipment is required for re-examination, and the original opening equipment cannot be used, which increases the space occupied. In addition, the existing medical test automation line sealing machine uses rack lifting, connecting rod cylinder rotation, head electric heating aluminum film, high-temperature melting of blood collection tubes and aluminum film welding to achieve packaging. The structure is complex, the processing is difficult, the cost is high, the head needs to be cleaned regularly, and the mechanical failure rate is high. A special film removal machine is required for later accessories. Therefore, it is of great significance to design a high-speed test tube capping machine for assembly line inspection.
