[0039] The working principle of the automatic tray loading machine defined in this application includes the following steps:

[0040] Blood collection tube arrangement: After the blood samples are sorted by the sorting machine, the blood collection tubes enter the sorting bin 21 and are arranged in one row of tube slots 223 under the action of the guide block 221.

[0041] Preparation for tube loading: The turning cylinder 53 controls the upper tube plate 51 to rotate until the upper tube groove 52 is horizontally opposite to the plurality of tube row grooves 223. Then, the tube pushing cylinder 233 is controlled to work, so that the push rod 232 pushes the blood collection tube in its corresponding tube row groove 223 into the corresponding upper tube groove 52.

[0042] Blood collection tube rack preparation: The clamping motor 624 cooperates with the clamping screw 625 to control the positioning block 622 to move to abut against the rear end of the blood collection tube rack 3, and controls the positioning piston rod 627 to extend upward to contact the front end of the blood collection tube rack 3. Then, the drive assembly 63 controls the movable plate 61 to move the blood collection tube rack 3 to the tube loading position 8;

[0043] Tube loading: The turning cylinder 53 controls the upper tube plate 51 to rotate downward until the upper tube groove 52 is opposite to the multiple placement grooves 31 arranged horizontally on the blood collection tube rack 3, so that the blood collection tubes in the upper tube groove 52 fall smoothly into the opposite placement grooves 31. Then, the above steps are repeated until the blood collection tube rack 3 is fully loaded with blood collection tubes, completing the tube loading process.

[0044] Blood collection tube rack delivery: The drive assembly 63 controls the movable plate 61 to move in the opposite direction to drive the blood collection tube rack 3 to return to the tube delivery position 9, and the positioning piston rod 627 moves downward to return to the tube delivery position. The feeding motor 72 cooperates with other components to drive the feeding plate 76 to move the blood collection tube rack 3 loaded with blood collection tubes laterally to send it out of the placement rack 4 for subsequent processing.

[0045] The present application limits the structural composition of the automatic tray loading machine and realizes the automatic insertion of blood collection tubes into the blood collection tube rack 3 through the mutual cooperation between various components. There is no need for medical staff to manually place them, which reduces the contact between medical staff and blood collection tubes, reduces the risk of cross infection, and ensures the integrity of blood collection tube samples; it significantly reduces manual operations, not only improves work efficiency, but also reduces errors caused by human errors, and ensures the reliability and safety of test results. This is particularly important for improving the work efficiency of hospitals and laboratories, especially when processing a large number of samples.

[0046] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of implementation of the present invention. In other words, equivalent changes and modifications made according to the scope of the patent application and the contents of the specification of the present invention should still fall within the scope of the present patent.
