As shown in fig. 1 and fig. 2, an embodiment of the test tube transporting apparatus 10 includes a carrier plate 100, a pushing mechanism 200, and a blocking mechanism 300.

Referring to fig. 1, 2 and 4, the carrier plate 100 is provided with a sliding groove 110, the end of the sliding groove 110 is provided with a dropping hole 111, and the test tube 20 can pass through the sliding groove 110 and be hung on the carrier plate 100.

Specifically, the supporting plate 100 is a flat plate, the sliding groove 110 is formed on the supporting plate 100 and penetrates through the upper and lower surfaces of the supporting plate 100, and the end of the sliding groove 110 is provided with a falling hole 111. The width of spout 110 is greater than the diameter of the shaft of test tube 20, and is less than the diameter of the cap of test tube 20, and the aperture of hole 111 that drops is greater than the diameter of the cap of test tube 20. In this way, the tube body of the test tube 20 can pass through the chute 110, and the test tube 20 can be hung on the carrier plate 100 by means of its cap, and when the test tube 20 is moved to the drop hole 111, the test tube 20 can drop from the drop hole 111.

As shown in fig. 2, the pushing mechanism 200 is disposed on the loading plate 100 and can push the test tube 20 to move along the length direction of the sliding slot 110. The pushing mechanism 200 is used to provide power to the test tube 20, so that the test tube 20 moves along the length direction of the sliding groove 110, and the test tube 20 moves to the drop hole 111 and drops from the drop hole 111 to the next station.

As shown in fig. 2 and 3, in particular, the pushing mechanism 200 includes a driving assembly and a pushing assembly 220 in driving connection with the driving assembly, and the driving assembly is used for driving the pushing assembly 220 to move, so that the pushing assembly 220 pushes the test tube 20 to move along the length direction of the chute 110.

In addition, in the process of pushing the test tube 20 toward the drop hole 111 by the pushing mechanism 200, the pushing mechanism 200 needs to stop before pushing the test tube 20 to the stopper 310 to wait for the next station to finish labeling on the previous test tube. When the pushing mechanism 200 stops operating, the test tube 20 will continue to move toward the drop hole 111 under the action of inertia, and when the test tube 20 moves to contact with the blocking member 310, the test tube 20 can be blocked by the blocking member 310 to stop sliding; after the next station finishes labeling the previous test tube, the pushing mechanism 200 can continue to push the test tube 20 to move toward the falling hole 111, and at this time, the test tube 20 can push away the blocking member 310 under the action of the pushing mechanism 200 and be pushed to the falling hole 111 to enter the next station.

In addition, in the process of pushing the test tube 20 toward the drop hole 111 by the pushing mechanism 200, the pushing mechanism 200 needs to stop before pushing the test tube 20 to the stopper 310 to wait for the next station to finish labeling on the previous test tube. When the pushing mechanism 200 stops operating, the test tube 20 will continue to move toward the drop hole 111 under the action of inertia, and when the test tube 20 moves to contact with the blocking member 310, the test tube 20 can be blocked by the blocking member 310 to stop sliding; after the next station finishes labeling the previous test tube, the pushing mechanism 200 can continue to push the test tube 20 to move toward the falling hole 111, and at this time, the test tube 20 can push away the blocking member 310 under the action of the pushing mechanism 200 and be pushed to the falling hole 111 to enter the next station. Compared with the mode that the test tube 20 is conveyed on the inclined slide way by the gravity, the mode that the test tube conveying device 10 is used for conveying the test tube 20 has high controllability, and the risk that the test tube 20 slides uncontrollably due to the gravity is eliminated; and set up barrier mechanism 300, can prevent that test tube 20 from just getting into the risk of next station when the action of pasting the mark has not been accomplished yet in next station.
