[0051] The working process of the sample scheduling device is as follows: the unlocking mechanism 50 works to unlock the limiting mechanism on the sample container rack carrier, and then the second moving component 30 drives the scheduling mechanism 40 to move to the sample container rack carrier, and the scheduling mechanism 40 is connected to the sample container rack in the sample container rack carrier, and then the second moving component 30 drives the scheduling mechanism 40 and the sample container rack to move to the accommodating space of the code scanning mechanism 60, and the code scanning mechanism 60 scans the code on the sample container to obtain the information of the sample in the sample container, and then the first moving component 20 drives the code scanning mechanism 60 and the sample container rack thereon to move according to the sample information, so that the sample can reach a preset position, such as the transport track of the sample analyzer.

[0052] The sample scheduling device uses an unlocking mechanism 50 to contact the limiting mechanism on the sample container rack carrier to limit the sample container rack, so that the sample container rack can be removed from the sample container rack carrier. The scheduling mechanism 40 is connected with the sample container rack stroke so that the second moving component 30 drives the sample container rack to move to the code scanning mechanism 60. The code scanning mechanism 60 scans the information of the sample container so that the first moving component 20 drives the sample container to move to a preset position. The structure is simple, which is conducive to saving equipment costs, and the entire process is automatic, which can improve the efficiency of sample analysis.

[0053] In one embodiment, the sample scheduling device includes a frame 10, and the first moving component 20, the second moving component 30, the scheduling mechanism 40, the unlocking mechanism 50 and the code scanning mechanism 60 are all arranged on the frame 10.

The driving wheel 212 and the driven wheel 213 are spaced apart along a first direction, and the belt 214 is tensioned and wrapped around the outer surfaces of the driving wheel 212 and the driven wheel 213. The mounting seat 22 is slidably connected to the frame 10, and the mounting seat is connected to the belt 214. When the driving member 211 is working, the driving wheel 212 rotates and drives the belt to move, thereby driving the mounting seat 22 to move along the first direction.

[0055] In one embodiment, along the conveying direction of the sample container rack in the accommodating space, the accommodating space has a first opening and a second opening, the first opening is located at one end of the accommodating space facing the sample container rack carrier, and the second opening is located at one end of the accommodating space facing away from the sample container rack carrier, that is, after the sample container rack leaves the sample container rack carrier, it enters the accommodating space from the first opening and leaves the accommodating space from the second opening to reach a preset position, such as a conveying track of a sample analyzer, etc. The sample container rack can also return to the accommodating space from the preset position through the second opening, or return to the sample container rack carrier through the first opening.

[0056] In a specific embodiment, please refer to Figure 2 The sample scheduling device includes a first sensor 71 and a second sensor 72. The detection area of ​​the first sensor 71 is at a first height, and the detection area of ​​the second sensor 72 is at a second height. The first height is greater than the second height. The first sensor is used to detect a first sample container type, and the second sensor is used to detect a second sample container type.

[0057] When entering the storage space, if the tube body of the sample container enters the detection area of ​​the first sensor 71 and the second sensor 72 at the same time, the first sensor 71 and the second sensor 72 both send out detection signals, and the sample container is identified as the first sample container type; when entering the storage space, if the tube body of the sample container only enters the detection area of ​​the second sensor 72, only the second sensor 72 sends out a detection signal, and the sample container is identified as the second sample container type; if neither the first sensor 71 nor the second sensor 72 sends out a detection signal, it is considered that no sample container has entered the storage space. The identification result of the sample container type can be used as reference information for external devices to perform various operations on the sample container.

[0058] In a specific embodiment, the sample scheduling device includes a third sensor 73, and the third sensor 73 is used to detect whether the sample container rack is stuck when entering or leaving the accommodating space through the first opening.

[0064] In a specific embodiment, the sample scheduling device includes a sixth sensor 76, and the sixth sensor 76 is used to detect whether the sample container rack is stuck when entering or leaving the accommodating space through the second opening.

[0065] When the sample container rack moves from the accommodating space to the preset position, or when the sample container rack returns from the preset position to the accommodating space, if a sample container rack is stuck between the accommodating space and the preset position, the fourth sensor 76 can send a detection signal, and the machine needs to be stopped for inspection.

[0066] The following will be combined Figure 3 to Figure 4 Various embodiments of the dispatch mechanism 40 are described.

[0067] In one embodiment, the scheduling mechanism 40 includes a first mounting frame 41, a third moving component 42 and a matching piece 43.

[0070] The scheduling mechanism 40 uses the third moving component 42 to drive the matching piece 43 to connect or separate with the sample container rack. When the matching piece 43 is connected to the sample container rack, it has the ability to drive the sample container rack to move. The structural principle is simple, the cost is low, and the working process is stable; the first slide groove 431 is set to a runway type, which is conducive to making the movement process of the sliding part 4222 more stable, and then making the movement process of the matching piece 43 more stable.

The second baffle 444 can enter the sensing slot of the second through-beam sensor 442 when the mating piece 43 is in the second working position. When the first baffle 443 blocks the sensing light in the first through-beam sensor 441, or the second baffle 444 blocks the sensing light in the second through-beam sensor 442, the scheduling drive 421 stops rotating to prevent over-movement.

[0083] In a more specific embodiment, the first sensing component 44 includes a first travel switch and a second travel switch.

The rotating drive 631 is used to drive the first rolling member 632 to move to drive the sample container to rotate, so that the code on the sample container enters the recognition area of ​​the code scanner 62.

[0108] The rotating assembly 63 of the code scanning mechanism 60 adopts a rotating driving member 631, a first rolling member 632, a clamping driving member 635 and a clamping assembly 633 to work together. The clamping assembly 633 generates a clamping force to press the sample container against the side wall of the first rolling member 632. The rotating driving member 631 drives the first rolling member 632 to rotate, and then drives the sample container to rotate, so that the code on the sample container can enter the recognition area of ​​the code scanner 62, so that the information about the sample in the sample container can be correctly read, ensuring that the scheduling equipment can normally transport the sample container rack, with a simple structure, efficient operation and low cost.

[0109] In one embodiment, the third mounting frame 61 includes a second bottom plate (not shown), a third side plate 612 and a fourth side plate 613. The third side plate 612 and the fourth side plate 613 are arranged parallel to and spaced apart from each other on the second bottom plate, and the gap between the third side plate 612 and the fourth side plate 613 forms a receiving space for placing a sample container.

The force-bearing direction of the elastic member 6332 is along the movement direction of the sliding seat 6333. The clamping driving member 635 can drive the clamping member 6331 to press against the sample container through the sliding seat 6333. After the clamping member 6331 presses against the sample container, it slides relative to the sliding seat 6333, so that the elastic member 6332 is deformed. The elastic member 6332 generates elastic force to push the clamping member 6331 to press the sample container.

[0113] As for the material selection of the elastic member 6332, it can be generally selected from elastic materials such as springs, rubbers and silicone.

[0114] In this embodiment, the clamping assembly 633 includes an elastic member 6332. After the clamping member 6331 contacts the sample container, the clamping member 6331 moves relative to the sliding seat 6333 to drive the elastic member 6332 to deform, so that the elastic force on the elastic member 6332 gradually increases, that is, the pressure of the clamping member 6331 on the sample container gradually increases, thereby avoiding the situation where the clamping member 6331 hits the sample container and causes damage to the sample container; in addition, by selecting the elastic coefficient of the elastic member 6332 and / or changing the size of the movement stroke of the sliding seat 6333, the size of the elastic force generated by the elastic member 6332 can be changed, thereby improving the stability of the clamping sample container rack while reducing the possibility of the sample container rack being crushed.

The elastic member 6332 is sleeved on the rod 63311, which can limit the deformation direction of the elastic member 6332 to the moving direction of the clamping member 6331 as much as possible, so that the elastic force generated by the elastic member 6332 acts on the clamping member 6331 as much as possible, and then acts on the sample container rack, which is conducive to improving the stability of the clamping sample container rack.

[0120] By providing two or more elastic members 6332, the elastic force generated by the elastic member 6332 can act on the connecting portion 63312 at multiple points, so that the force on the connecting portion 63312 is more uniform, and the force of the rolling portion 63313 acting on the sample container is more uniform, thereby improving the stability of pushing the sample container and preventing the sample container from being damaged due to concentrated force.

[0121] In a more specific embodiment, there are two rolling parts 63313.
