in this embodiment, two sets of driving assemblies are provided, one set of driving assemblies is used for driving the sample rack 10 to scan the code bit 501 for code scanning, and the other set of driving assemblies is used for driving the sample rack 10 to the sampling bit 502, the puncturing bit and the sample stripping bit 503 for sampling, puncturing and sample stripping.

Specifically, the two groups of driving components independently act and work in a split-work cooperation manner to relay-drive the sample rack 10, so that the time for the lifting module 20 to initialize to the original point can be shortened, and the sample rack 10 can still keep high-efficiency operation under various special conditions.

In this embodiment, referring to fig. 1 and 2, a plurality of test tube positions 11 are disposed on a sample rack 10, and a driving hole 12 is formed at the bottom of the sample rack 10. Referring to fig. 3 to 6, the first group of driving assemblies includes a first driving unit 301 and a first lifting module 201, the first driving unit 301 drives the first lifting module 201 to reciprocate along the dispatching guide rail 40, and the first lifting module 201 drives the connecting portion 21 thereon to perform lifting motion; the second group of driving components comprises a second driving unit 302 and a second lifting module 202, the second driving unit 302 drives the second lifting module 202 to reciprocate and move transversely along the dispatching guide rail 40, and the second lifting module 202 drives the connecting part 21 on the second lifting module to do lifting motion; after the connecting part 21 is lifted, the sample rack 10 can be inserted and hooked; the connecting part 21 is separated from the sample rack 10 after descending; when the first lifting module 201 acts on the sample rack 10, the first driving unit 301 drives the first lifting module 201 to move, so that the sample rack 10 can move along with the first lifting module 201; when the second lifting module 202 acts on the sample rack 10, the second driving unit 302 drives the second lifting module 202 to move, so that the sample rack 10 can move along with the second lifting module 202.

The first set of drive assemblies cycles through the second round of motion while the second set of drive assemblies drives the 1 st sample rack 101 to the corresponding position. That is, the first group of driving components scans the 2 nd sample holder 102 to the scanning bit 501 in synchronization and performs a series of actions, which are the same as the actions performed by the first group of driving components on the 1 st sample holder 101. After the 2 nd sample rack 102 finishes the code scanning operation, the 2 nd sample rack 102 is driven by the second set of driving components to the sampling position 502, the puncturing position and the sample ejecting position 503 so as to perform sampling, puncturing and sample ejecting on the sample. Specifically, as shown in fig. 10, the test tube position No. 1 of the sample rack 1 101 is sampling, the test tube position No. 1 of the sample rack 2 102 is scanning, and the test tube and cap are detected; then, the 1 st sample rack 101 moves a certain distance to the left to sample the No. 2 test tube position, and meanwhile, the 2 nd sample rack 102 also moves the same distance to the left to scan and detect the No. 2 test tube position; then, the 1 st sample rack 101 moves a certain distance to the left for sampling the test tube position 3, and simultaneously, the 2 nd sample rack 102 also moves the same distance to the left for scanning and detecting the test tube position 3 … … to the test tube position 10. As shown in FIG. 11, the test tube site No. 10 of the 1 st sample rack 101 is being sampled, and the test tube site No. 10 of the 2 nd sample rack 102 is being scanned and tested.

As shown in fig. 12, the second driving unit 302 drives the second lifting module 202 to move to the left, so as to drive the 1 st sample rack 101 to move to the sample unloading position 503, and the 1 st sample rack 101 can be removed by other devices. The first lifting module 201 is separated from the 2 nd sample rack 102, and the first driving unit 301 drives the first lifting module 201 to move rightwards to return to the first initial position, and the same action is ready to be performed on the 3 rd sample rack 103.

As shown in FIG. 13, the test tube site No. 1 of the 2 nd sample rack 102 is being sampled, and the test tube site No. 1 of the 3 rd sample rack 103 is being scanned and tested.

And circulating the steps, the first group of driving single assemblies and the second group of driving assemblies drive the sample racks in a relay manner to ensure the sampling speed until code scanning, sampling, puncturing and sample withdrawing of all the sample racks are completed, and the method enables the sample racks to still keep high-efficiency operation under various special conditions.

The invention also provides a sample analyzer, comprising a reagent sample needle module, a reagent tray module, an incubation tray module, a detection module and a scheduling module, wherein:

the reagent sample needle module is used for sucking a reagent and a sample and placing the reagent and the sample in the reaction cup;

the reagent disk module is used for storing reagents and keeping the temperature of the reagents in a constant temperature state;

the incubation disc module is used for incubating the object to be tested to meet the conditions required by the biochemical reaction;

and the detection module is used for detecting the object to be detected to obtain a detection result.

A scheduling module for scheduling reagents and samples, the scheduling module comprising a sample rack scheduling system as described above.

In summary, the sample rack driving and dispatching device, the sample rack dispatching system and the sample analyzer provided by the embodiment of the invention have strong universality and are suitable for sample racks used in a single machine or an online manner; the requirement on the shape of the sample frame is low, and only a driving hole is formed at the bottom; the sample rack scheduling adopts a driving mode of at least two groups of driving components, and the sample rack is driven independently through each group of driving components, is in work division cooperation and is driven in a relay mode, so that the movement efficiency of the sample rack is improved, and the speed requirement required by the whole machine is ensured.
