Implementation

[0038] The technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0039] like Figure 1 , Figure 2 As shown, a sample rack conveying device includes a transfer device 1, which is used to connect the sample injection device 2 and the sample transfer track 3; a first propulsion mechanism 4, which is used to push the sample rack on the transfer device 1 to the sample transfer track 3; and a second propulsion mechanism 5, which is used to push the sample rack on the transfer device 1 to the sample injection device 2.

[0040] The utility model connects the sample injection device and the sample conveying track through the adapter device, so that the sample rack can be normally conveyed between the two. At the same time, due to the installation of the adapter device between the sample injection device and the sample conveying track, an extra space is formed between the sample analyzer and the sample injection device, which can facilitate the installation of the display, such as Figure 4 As shown, the display is installed at a position aligned with the adapter 1 through the mounting bracket 6, which not only facilitates the installation of the display, but also ensures that the sample rack is stably and smoothly transferred between the sample injection device 2 and the sample transfer track 3.

[0041] like Figure 2 , Figure 3 As shown, the adapter 1 includes a carrying track 7, which is docked with the sample transfer track 3, and the sample rack can slide relative to the carrying track 7. Baffles 8 are provided on both sides of the carrying track 7, and the baffles 8 at both ends of the carrying track 7 form a trumpet-shaped opening structure, which is convenient for the sample rack to enter and exit the carrying track 7. A channel bottom plate 9 is provided at the bottom of the carrying track 7, and chamfers are provided at both ends of the channel bottom plate 9 to avoid scratches when the sample rack enters and exits the carrying track 7. There are multiple carrying tracks 7, and three are provided in the embodiment of the utility model, including a return track 10, a conventional injection track 11 and an emergency injection track 12 arranged in sequence.

[0042] The adapter device 1 also includes a mounting base plate 13, a mounting vertical plate 14, a support plate 15 and a connecting base plate 16; the mounting vertical plate 14 is fixedly mounted on the mounting base plate 13; the support plate 15 is fixed to the upper part of the mounting vertical plate 14, and adopts a lightweight design so that it is consistent with the height of the sample transmission track 3, the connecting base plate 16 is fixed on the support plate 15, and the channel base plate 9 and the baffle 8 are fixed on the connecting base plate 16.

[0043] Three detection optical couplers 17 are arranged on one side of each carrying rail 7 for accurately detecting the position of the sample rack on the carrying rail 7 .

[0044] After the barcode identification, the sample rack is sent to the transfer device 1 through the first push mechanism 4, and then the first push mechanism 4 continues to move, pushing the sample rack into the sample conveying track 3 at the front end of the sample analyzer, and the sample conveying track 3 carries the sample rack to each sample analyzer for sample testing. After the test task is completed, the sample rack is carried to the transfer device 1 by the sample conveying track 3, and the second push mechanism 5 pushes the sample rack to the dispatching trolley (not shown) set at the sample injection device 2, and the dispatching trolley carries the sample rack to the temporary storage area (not shown) in the sample injection device 2, waiting for re-inspection or recycling.

[0045] Furthermore, the first propulsion mechanism 4 and the second propulsion mechanism 5 are both arranged on one side of the return track 10 .

[0046] like Figure 2 , Figure 3 As shown, the first propulsion mechanism 4 includes a first driving mechanism, a first push rod 18 and a push plate 19; the push plate 19 is fixed on the first push rod 18, straddling the conventional injection track 11 and the emergency injection track 12, and can push the sample racks on the conventional injection track 11 and the emergency injection track 12 at the same time; the first push rod 18 is arranged on the first driving mechanism, and the first driving mechanism can drive the first push rod 18 to move, thereby driving the push plate 19 to move, and the push plate 19 drives the sample rack on the carrying track 7 to move.

The second driving mechanism can drive the second push rod 20 to move, and then drive the rotating plate 21 to move. Before the sample rack moves from the sample conveying track 3 to the return track 10, the rotating plate 21 moves toward the limit plate 22. After contacting the limit plate 22, the rotating plate 21 compresses the torsion spring, so that the rotating plate 21 rotates toward the outside of the return track 10, and the rotating plate 21 moves out of the return track 10 to avoid interfering with the movement of the sample rack from the sample conveying track 3 to the return track 10; when the sample rack moves from the sample conveying track 3 to the return track 10, the second push rod 20 carries the rotating plate 21 to move away from the limit plate 22, and the rotating plate 21 slowly loses the obstruction of the limit plate 22, rotates toward the inside of the return track 10, and extends into the return track 10, thereby being able to move the sample rack on the return track 10 to the dispatching trolley at the sample injection device 2.
