Description

Technical Field

[0001] The utility model belongs to the technical field of in vitro diagnostic instruments, and in particular relates to a sample rack track transmission device and a full-automatic high-speed biochemical analyzer. Background Art

[0002] With the development of medical testing technology, full-automatic high-speed biochemical analyzers have become essential equipment for large or extra-large clinical laboratories and commercial laboratories. However, existing full-automatic high-speed biochemical analyzers often have problems such as poor stability and low efficiency during sample transmission, which affect the accuracy of test results and the testing efficiency.

[0003] In order to meet the requirements of automated analysis, sample rack track transmission devices are widely used in biochemical analyzers. Currently, sample rack track transmission devices on the market generally include a regular sample track, an emergency sample track, and a return sample track for the transportation of ordinary samples, emergency samples, and recycled samples. Chinese Patent CN207036875U discloses a sample transmission system with transmission and return functions, including an emergency sample track, a regular sample track, and a recycled sample track, and a sample rack track switching device is provided in the middle of the emergency sample track, the regular sample track, and the recycled sample track; a telescopic positioning type sample transmission device and a sample rack limit blocking device are respectively provided on the emergency sample track, the regular sample track, and the recycled sample track before the sample rack track switching device, and pre-pressing devices are provided at the sampling positions of the emergency sample track and the regular sample track. Through the coordinated use of multiple devices, accurate and stable transmission and recycling of the sample rack are achieved. However, this utility model cannot achieve high-speed switching of sample racks. Only after the sample rack at the sampling position leaves can the next sample rack enter the sampling position for sampling, and continuous and uninterrupted sampling by the sample needle cannot be achieved. At the same time, this utility model cannot take into account the sampling of electrolyte samples, and the efficiency is relatively low.

[0004] High-speed biochemical analyzers have strict requirements for the running speed of the track and the coherence of the sample racks. The current sample rack track transmission devices cannot meet the requirements of high-speed continuous sampling, and problems such as missed sampling and speed reduction are likely to occur during the sample rack switching process. Moreover, most clinical test analyzers can only perform separate detections of biochemical and electrolyte items. If a patient needs to undergo biochemical test items and electrolyte test items, doctors will test the sample tubes in biochemical test instruments and electrolyte test instruments respectively, resulting in low detection efficiency. Summary of the Utility Model

[0005] The purpose of this utility model is to overcome the defects of the above-mentioned existing technologies and provide a sample rack track transmission device and a full-automatic high-speed biochemical analyzer, which can be compatible with the electrolyte detection requirements and solve the problems of speed reduction and missed sampling caused by discontinuous sample rack switching.

[0056] In the following embodiments or examples, if there is no particularly described functional component or structure, it means that they are all conventional components or conventional structures adopted in the art to achieve the corresponding functions.

[0057] The present utility model provides a sample rack track conveying device, as Figures 1 to 10 shown, including:

[0058] Track frame 1,

[0059] A conventional sample track 2, an emergency sample track 3, and a return sample track 4 installed above the track frame 1, the conventional sample track 2, the emergency sample track 3, and the return sample track 4 are arranged in parallel,

[0060] and a first driving mechanism 5, a second driving mechanism 6, and a third driving mechanism 7 for driving the sample rack 12 to move within the conventional sample track 2,

[0061] a fourth driving mechanism 8 and a fifth driving mechanism 9 for driving the sample rack 12 to move within the emergency sample track 3,

[0063] a seventh driving mechanism 11 for switching the sample rack 12 from the conventional sample track 2 / emergency sample track 3 to the return sample track 4, or from the emergency sample track 3 to the conventional sample track 2.

[0064] The sample rack track transmission device of the present utility model can respectively control the movement of the sample rack 12 at the electrolyte sampling position and the analyzer sampling position on the conventional sample track 2 and the emergency sample track 3 by arranging driving mechanisms outside the conventional sample track 2 and the emergency sample track 3, thereby realizing the detection of samples of the electrolyte module and the analyzer module; through the mutual cooperation of the second driving mechanism 6 and the third driving mechanism 7, the continuous switching of the sample rack 12 on the conventional sample track 2 and the continuous sampling of samples can be realized.

[0065] Embodiment 1

[0066] From Figure 5 It can be seen that a first driving mechanism 5 is arranged outside the conventional sample track 2 for driving the sample rack 12 to stay at the corresponding electrolyte sampling position on the conventional sample track 2.

[0067] The first driving mechanism 5 includes a first motor 5-2 and a first guide plate 5-8 fixedly assembled on a first X-axis mounting plate 5-1, a first synchronous belt transmission mechanism 5-3 drivingly connected to the output end of the first motor 5-2, and a first Y-axis mounting plate 5-4 fixedly connected to the first synchronous belt transmission mechanism 5-3. A first baffle 5-5 is slidably connected to the first Y-axis mounting plate 5-4. A first sensor fixing plate 5-6 is installed beside the first baffle 5-5, and a first sample rack detection sensor 5-9 is fixed on the first sensor fixing plate 5-6. A first roller 5-7 is pivotally connected to the first baffle 5-5. The first roller 5-7 is at the same height as the first guide plate 5-8. One end face of the first guide plate 5-8 is an inclined surface that can cooperate with the first roller 5-7. When the first roller 5-7 moves along the inclined surface of the first guide plate 5-8, the first baffle 5-5 can extend into or out of the conventional sample track 2.

[0068] Working principle of the first driving mechanism 5: In the initial state, the first baffle 5-5 is located outside the conventional sample track 2, and the first roller 5-7 is located at the outermost side of the inclined surface of the first guide plate 5-8. After the sample stage sends sample rack information to the conventional sample track 2, the first roller 5-7 starts to move along the inclined surface of the first guide plate 5-8 under the drive of the first motor 5-2. The first roller 5-7 leaves the inclined surface of the first guide plate 5-8 and runs to the sample rack blocking position. At this time, the first baffle 5-5 is located inside the conventional sample track 2. When the sample rack 12 comes to the blocking position along the flat belt of the conventional sample track 2, the first sample rack detection sensor 5-9 detects the sample rack signal. The first baffle 5-5 stops at the target sampling position after being driven by the first motor 5-2 and blocks the movement of the sample rack 12. After the sample is taken away for detection, the first motor 5-2 drives the first baffle 5-5 to continue moving to the next target sampling position. After all the samples in the sample rack 12 are taken away, the first baffle 5-5 returns to the initial state under the drive of the first motor 5-2, and the sample rack 12 enters the next program through flat belt transmission.

[0069] The "sliding connection" in this embodiment is a linear guide rail sliding connection. Specifically, the guide rail in the linear guide rail is fixed on the first Y-axis mounting plate 5-4, and the first baffle 5-5 is fixed on the slider in the linear guide rail.

[0070] Embodiment 2

[0071] Based on Embodiment 1, the following design can also be adopted in this embodiment: The vertical movement of the first baffle 5-5 can be realized by the structure of the first motor 5-2 driving the synchronous belt, or by the structure of the first motor 5-2 driving the gear meshing, or by the structure of the first motor 5-2 directly driving the first baffle 5-5 to rotate, so as to realize the first baffle 5-5 extending into or out of the conventional sample track 2.

[0072] Example 3

[0073] from Figure 8 It can be seen that a fourth driving mechanism 8 is provided on the outer side of the emergency sample track 3 for driving the sample rack 12 to stay at the corresponding electrolyte sample suction position on the emergency sample track 3 .

[0074] The fourth driving mechanism 8 comprises a fifth motor 8-2 fixedly mounted on the third X-axis mounting plate 8-1, a second guide plate 8-9 and a third guide plate 8-10, a third synchronous belt transmission mechanism 8-3 drivingly connected to the output end of the fifth motor 8-2, and a third Y-axis mounting plate 8-4 fixedly connected to the third synchronous belt transmission mechanism 8-3, a fourth baffle plate 8-5 slidably connected to the third Y-axis mounting plate 8-4, a fourth sensor fixing plate 8-6 installed next to the fourth baffle plate 8-5, and a fourth sample rack detection sensor 8-7 fixed to the fourth sensor fixing plate 8-6. A second roller 8-8 is axially connected to the fourth baffle plate 8-5, and the second roller 8-8 is at the same height as the second guide plate 8-9 and the third guide plate 8-10, and one end surface of the two guide plates is an inclined surface that can match the second roller 8-8, and when the second roller 8-8 moves along the inclined surfaces of the two guide plates, the fourth baffle plate 8-5 can extend into or out of the emergency sample track 3.

[0075] Working principle of the fourth driving mechanism 8: In the initial state, the fourth baffle 8-5 is located on the outside of the emergency sample track 3, and the second roller 8-8 is located on the outermost side of the slope of the second guide plate 8-9. When the sample table sends the sample rack information to the emergency sample track 3, the second roller 8-8 starts to move along the slope of the second guide plate 8-9 under the drive of the fifth motor 8-2. The second roller 8-8 leaves the slope of the second guide plate 8-9 and runs to the sample rack blocking position. At this time, the fourth baffle 8-5 is located on the inner side of the emergency sample track 3. When the sample rack 12 comes to the blocking position along the flat belt of the emergency sample track 3, the fourth sample rack detection sensor 8-7 detects the sample rack signal, and the fourth baffle 8-5 moves on the fifth motor 8-2. After reaching a certain target sample suction position under the drive of the motor 8-2, the sample rack 12 stops and stops moving. After the sample is taken away for detection, the fifth motor 8-2 drives the fourth baffle 8-5 to continue to move to the next target sample suction position. After the sample in the sample rack 12 is completely taken away, the fourth baffle 8-5 moves to the outermost side of the inclined surface of the third guide plate 8-10 under the drive of the fifth motor 8-2. At this time, the fourth baffle 8-5 is located outside the emergency sample track 3, and the sample rack 12 enters the next program through the flat belt drive. When the fourth sample rack detection sensor 8-7 cannot detect the sample rack signal, the fourth baffle 8-5 returns to the initial state under the drive of the fifth motor 8-2.

[0076] The "sliding connection" in this embodiment is a linear guide rail sliding connection, specifically: in the linear guide rail, the guide rail is fixed on the third Y-axis mounting plate 8-4, and the fourth baffle 8-5 is fixed on the slider in the linear guide rail.

[0077] Embodiment 4

[0078] On the basis of Embodiment 2, the following design can also be adopted in this embodiment: the vertical movement of the fourth baffle 8-5 can be realized by the structure of the fifth motor 8-2 driving the synchronous belt, or by the structure of the fifth motor 8-2 driving the gear meshing, or by the structure of the fifth motor 8-2 directly driving the fourth baffle 8-5 to rotate, so as to realize the fourth baffle 8-5 extending into or out of the emergency sample track 3.

[0079] Embodiment 5

[0080] From Figure 6 and Figure 7 It can be seen that a second driving mechanism 6 and a third driving mechanism 7 are also arranged outside the conventional sample track 2, and the sample rack 12 is driven to stay at the corresponding analyzer sampling position through the mutual cooperation of the second driving mechanism 6 and the third driving mechanism 7. The second driving mechanism 6 drives the sample rack to move between the first sample tube and the ninth sample tube. After the sample is drawn from the first sample tube to the ninth sample tube, the second driving mechanism 6 releases the sample rack 12, and the sample rack 12 moves to the third driving mechanism 7 under the transmission of the flat belt of the conventional sample track 2. The baffle at the third driving mechanism 7 is located inside the track, blocking the movement of the sample rack 12, and the two sample needles at the blocking position are exactly above the center point of the tenth sample tube. When the third sample rack detection sensor 7-5 of the third driving mechanism 7 detects that the sample rack 12 is in place, the sample needle can perform normal sample addition. After the sample in the tenth sample tube is added, the third driving mechanism 7 drives the third baffle 7-3 to rotate to the outside of the track, and the sample in the sample rack 12 is drawn out and enters the next process under the drive of the flat belt. After the second driving mechanism 6 releases the sample rack 12, it returns to the waiting position and waits for the next sample rack 12 to be in place. When the second sample rack detection sensor 6-9 of the second driving mechanism 6 detects that the sample rack 12 is in place, it first judges whether the previous sample rack 12 has completed sample addition. If the sample addition has been completed, the second driving mechanism 6 drives the sample rack 12 to move in the conventional sample track 2 and repeats the above process.

[0081] The second driving mechanism 6 includes a second motor 6-2 fixedly assembled on a second X-axis mounting plate 6-1, a second synchronous belt transmission mechanism 6-3 drivingly connected to the output end of the second motor 6-2, and a first bottom plate 6-4 fixedly connected to the second synchronous belt transmission mechanism 6-3. A second Y-axis mounting plate 6-5 is fixedly connected to the first bottom plate 6-4. A third motor 6-6 is fixedly assembled on the second Y-axis mounting plate 6-5. The output end of the third motor 6-6 is connected to a second baffle 6-7, and the second baffle 6-7 can extend into or out of the conventional sample track 2. A second sensor fixing plate 6-8 is installed beside the second baffle 6-7, and a second sample rack detection sensor 6-9 is fixed on the second sensor fixing plate 6-8. A first connecting plate 6-10 is fixedly connected to the first bottom plate 6-4. One end of the first connecting plate 6-10 is connected to a first rotating electromagnet fixing plate 6-11, a rotating electromagnet 6-12 is fixedly connected to the first rotating electromagnet fixing plate 6-11, and a first pushing plate 6-13 is fixed to the end of the rotating electromagnet 6-12. The first pushing plate 6-13 can extend into or out of the conventional sample track 2.

[0082] Working principle of the second driving mechanism 6: In the initial state, the second baffle 6-7 is located inside the conventional sample track 2, and the first pushing plate 6-13 is located outside the conventional sample track 2. The second baffle 6-7 moves to the waiting position driven by the second motor 6-2. When the second sample rack detection sensor 6-9 detects that the sample rack 12 is in place, the first pushing plate 6-13 rotates from the outside to the inside of the conventional sample track 2 driven by the rotating electromagnet 6-12. At this time, the distance between the second baffle 6-7 and the first pushing plate 6-13 is the distance of one sample rack 12. Both the second baffle 6-7 and the first pushing plate 6-13 are located inside the conventional sample track 2 to clamp the sample rack 12 and move it. The second baffle 6-7 moves to the target sampling position driven by the second motor 6-2. After the sample is taken away for detection, the second baffle 6-7 moves to the next target sampling position driven by the second motor 6-2, and so on until it moves to the last target sampling position. When the sample at the last target sampling position is sucked up, the second baffle 6-7 moves from the last target sampling position to the sample passing position. The second baffle 6-7 rotates from the inside to the outside of the conventional sample track 2 and returns to the sample waiting position driven by the third motor 6-6. The first pushing plate 6-13 rotates from the inside to the outside of the conventional sample track 2 driven by the rotating electromagnet 6-12.

[0083] The third driving mechanism 7 includes a first motor fixing plate 7-1 fixedly assembled outside the conventional sample track 2, a fourth motor 7-2 fixedly connected to the first motor fixing plate 7-1, and a third baffle 7-3 connected to the output end of the fourth motor 7-2. The third baffle 7-3 can extend into or out of the conventional sample track 2. The first motor fixing plate 7-1 is also fixedly connected with a third sensor fixing plate 7-4, and a third sample rack detection sensor 7-5 is fixed on the third sensor fixing plate 7-4. When the sample rack 12 at the detection position of the conventional sample track 2 is not processed completely, the third driving mechanism 7 can prevent the subsequent sample rack 12 from moving forward.

[0084] Working principle of the third driving mechanism 7: In the initial state, the third baffle 7-3 is located inside the conventional sample track 2, and the third baffle 7-3 can prevent the sample rack 12 from moving forward. When the third sample rack detection sensor 7-5 detects the sample rack 12, if the sample at position 10 needs to be sampled, the sample needle starts to suck the sample at position 10. After the sample at position 10 is sucked, the fourth motor 7-2 drives the third baffle 7-3 to rotate, so that the third baffle 7-3 extends out of the conventional sample track 2. If the sample at position 10 does not need to be sampled, the fourth motor 7-2 drives the third baffle 7-3 to rotate, so that the third baffle 7-3 extends out of the conventional sample track 2, and the sample rack 12 enters the next program along the flat belt of the conventional sample track 2. When the sample rack detection sensor 7-5 detects that the sample rack 12 has left, the fourth motor 7-2 drives the third baffle 7-3 to rotate, so that the third baffle 7-3 extends into the conventional sample track 2 to block the sample rack 12 from being transported on the conveyor belt.

[0085] The working principle of the cooperation between the second driving mechanism 6 and the third driving mechanism 7 to switch the sample rack 12: In the initial state, the third baffle 7-3 of the third driving mechanism 7 is located inside the conventional sample track 2, the second baffle 6-7 of the second driving mechanism 6 is located inside the conventional sample track 2, and the first push plate 6-13 of the second driving mechanism 6 is located outside the conventional sample track 2. First, the second baffle 6-7 moves to the waiting position under the drive of the second motor 6-2. When the second sample rack detection sensor 6-9 detects that the sample rack 12 is in place, the first push plate 6-13 rotates from the outside of the conventional sample track 2 to the inside under the drive of the rotary electromagnet 6-12. There is a distance of one sample rack between the second baffle 6-7 and the first push plate 6-13. At this time, both the second baffle 6-7 and the first push plate 6-13 are located inside the conventional sample track 2 to clamp the sample rack 12 and move it. Then, the second baffle 6-7 moves to the target sampling position under the drive of the second motor 6-2. After the sample is taken away for detection, the second baffle 6-7 moves to the next target sampling position under the drive of the second motor 6-2, and so on until it moves to the last target sampling position. When the sample at the last target sampling position is sucked up, the second baffle 6-7 moves to the sample passing position under the drive of the second motor 6-2. The second baffle 6-7 rotates to the outside of the conventional sample track 2 under the drive of the third motor 6-6. The first push plate 6-13 rotates from the inside of the conventional sample track 2 to the outside under the drive of the rotary electromagnet 6-12. The sample rack 12 continues to move under the drive of the flat belt. The second baffle 6-7 returns to the waiting position under the drive of the second motor 6-2. When the sample rack detection sensor 7-5 detects the sample rack 12, if the sample at position 10 needs to be sampled, the sample needle starts to suck the sample at position 10. After the sample at position 10 is sucked up, the fourth motor 7-2 drives the third baffle 7-3 to rotate, so that the third baffle 7-3 extends out of the conventional sample track 2. If the sample at position 10 does not need to be sampled, the fourth motor 7-2 drives the third baffle 7-3 to rotate, so that the third baffle 7-3 extends out of the conventional sample track 2. The sample rack 12 enters the next program under the drive of the flat belt. When the sample rack detection sensor 7-5 detects that the sample rack 12 has left, the fourth motor 7-2 drives the third baffle 7-3 to rotate, so that the third baffle 7-3 extends into the conventional sample track 2 to block the sample rack 12 from being transported on the conveyor belt. Another sample rack 12 repeats the above steps. The second baffle 6-7 in the second driving mechanism 6 returns to the waiting position under the drive of the second motor 6-2 and the sample rack detection sensor 7-5 in the third driving mechanism 7 detects the sample rack 12 at the same time. After the second baffle 6-7 returns to the waiting position under the drive of the second motor 6-2, if the second sample rack detection sensor 6-9 does not detect that the sample rack 12 is in place, it remains waiting; if the second sample rack detection sensor 6-9 detects that the sample rack 12 is in place, first judge whether the sample rack 12 in the third driving mechanism 7 has finished sampling. If it has not finished sampling, it remains waiting. If it has finished sampling, repeat the above sampling process.

[0086] In this embodiment, the third driving mechanism 7 is provided to cache the sample rack 12, and the second driving mechanism 6 and the third driving mechanism 7 cooperate with each other, so that when the first sample rack 12 detects the tenth sample, the second sample rack 12 has been clamped by the second driving mechanism 6, and when the first sample rack has finished detecting the tenth sample, the second sample rack 12 is pushed to the sample adding position. The cooperation between the second driving mechanism 6 and the third driving mechanism 7 realizes the rapid switching of the sample rack 12, and the continuous sampling of samples without interruption, thereby ensuring the continuous transportation of samples.

[0087] Example 6

[0088] The sample rack 12 for emergency or retesting is loaded with samples in the loading area within the emergency sample track 3. Since double sample needles are used for loading samples, the two loading points are not at the same position. The sample rack 12 within the emergency sample track 3 can be moved by the fifth driving mechanism 9 arranged on the outside of the emergency sample track 3 to meet the needs of loading samples at two points.

[0089] from Figure 9 It can be seen that the fifth driving mechanism 9 includes a sixth motor 9-2 and a fourth guide plate 9-12 fixedly mounted on the fourth X-axis mounting plate 9-1, a fourth synchronous belt transmission mechanism 9-3 transmission-connected to the output end of the sixth motor 9-2, and a second base plate 9-4 fixedly connected to the fourth synchronous belt transmission mechanism 9-3, a fourth Y-axis mounting plate 9-5 fixedly connected to the second base plate 9-4, a seventh motor 9-6 fixedly mounted on the fourth Y-axis mounting plate 9-5, an output end of the seventh motor 9-6 is connected to a fifth baffle plate 9-7, a fifth sensor fixing plate 9-8 is installed next to the fifth baffle plate 9-7, and a fifth sample rack detection sensor 9-9 is fixed on the fifth sensor fixing plate 9-8. The second bottom plate 9-4 is also slidably connected to a second push plate 9-10, and a third roller 9-11 is axially connected to the second push plate 9-10. The third roller 9-11 is at the same height as the fourth guide plate 9-12. One end face of the fourth guide plate 9-12 is an inclined surface that can cooperate with the third roller 9-11. When the third roller 9-11 moves along the inclined surface of the fourth guide plate 9-12, the second push plate 9-10 can extend into or out of the emergency sample track 3.

[0090] Working principle of the fifth driving mechanism 9: In the initial state, the second push plate 9-10 is located outside the emergency sample track 3, the third roller 9-11 is located at the outermost side of the inclined plane of the fourth guide plate 9-12, and the fifth baffle 9-7 is located inside the emergency sample track 3. The fifth baffle 9-7 moves to the blocking position of the sample rack 12 under the drive of the sixth motor 9-2. At this time, the second push plate 9-10 is located outside the emergency sample track 3. When the sample rack 12 arrives at the blocking position along the flat belt of the emergency sample track 3, after the fifth sample rack detection sensor 9-9 detects the sample rack 12, the third roller 9-11 starts to move along the inclined plane of the fourth guide plate 9-12 under the drive of the sixth motor 9-2. The third roller 9-11 leaves the inclined plane of the fourth guide plate 9-12 and reaches the waiting position. The second push plate 9-10 and the fifth baffle 9-7 are separated by the distance of one sample rack. At this time, both the second push plate 9-10 and the fifth baffle 9-7 are located inside the emergency sample track 3 and clamp the sample rack 12 to move. The fifth baffle 9-7 moves to the target sampling position under the drive of the sixth motor 9-2. After the sample is taken away for detection, the fifth baffle 9-7 moves to the next target sampling position under the drive of the sixth motor 9-2, and so on until it moves to the last target sampling position. When the sample at the last target sampling position is sucked up, the fifth baffle 9-7 moves from the last target sampling position to the sample passing position. The fifth baffle 9-7 rotates to the outside of the emergency sample track 3 under the drive of the seventh motor 9-6. The sample rack 12 runs along the flat belt to the next process. The fifth baffle 9-7 returns to the blocking position of the sample rack 12 under the drive of the sixth motor 9-2. The fifth baffle 9-7 rotates to the inside of the emergency sample track 3 under the drive of the seventh motor 9-6. When there is another sample rack 12, the above steps are repeated.

[0091] In this embodiment, the "sliding connection" is a linear guide rail sliding connection. Specifically, the guide rail in the linear guide rail is fixed on the second bottom plate 9-4, and the second push plate 9-10 is fixed on the slider in the linear guide rail.

[0092] Embodiment 7

[0093] On the basis of Embodiment 6, this embodiment can also adopt the following design: The vertical movement of the second push plate 9-10 / the fifth baffle 9-7 can be realized by the structure of a motor-driven synchronous belt, or by the structure of a motor-driven gear meshing, or by the structure of directly driving the second push plate 9-10 to rotate by the motor, so as to realize the second push plate 9-10 / the fifth baffle 9-7 extending into or out of the emergency sample track 3.

[0094] Embodiment 8

[0095] The sample rack 12 that has been detected or needs to be retested returns to the sample rack recovery area through the return sample track 4. The sample rack 12 in the return sample track 4 can be returned by the sixth driving mechanism 10 arranged outside the return sample track 4.

[0096] From Figure 10 It can be seen that the sixth driving mechanism 10 includes an eighth motor 10-2 and a fifth guide plate 10-8 fixedly assembled on the fifth X-axis mounting plate 10-1, a fifth synchronous belt transmission mechanism 10-3 drivingly connected to the output end of the eighth motor 10-2, a fifth Y-axis mounting plate 10-4 fixedly connected to the fifth synchronous belt transmission mechanism 10-3. A first push rod fixing plate 10-5 is connected to the fifth Y-axis mounting plate 10-4. The first push rod fixing plate 10-5 is connected to a first push rod 10-6. A fourth roller 10-7 is pivotally connected to the first push rod 10-6. The fourth roller 10-7 is at the same height as the fifth guide plate 10-8. One end face of the fifth guide plate 10-8 is an inclined surface capable of cooperating with the fourth roller 10-7. When the fourth roller 10-7 moves along the inclined surface of the fifth guide plate 10-8, the first push rod 10-6 can extend into or retract from the return sample track 4. A sample rack detection sensor 10-9 is provided inside the return sample track 4.

[0097] Working principle of the sixth driving mechanism 10: In the initial state, the first push rod 10-6 is located inside the return sample track 4, and the fourth roller 10-7 is separated from the fifth guide plate 10-8. When the sixth sample rack detection sensor 10-9 detects that the sample rack 12 is in place, the fourth roller 10-7 starts to move along the inclined surface of the fifth guide plate 10-8 under the drive of the eighth motor 10-2. When the fourth roller 10-7 reaches the outermost side of the inclined surface of the fifth guide plate 10-8, at this time, the first push rod 10-6 is located outside the return sample track 4, and the sample rack 12 moves forward under the transmission of the flat belt of the return sample track 4. When the outlet sample rack detection sensor of the return sample track 4 detects the in-place signal of the sample rack 12, the fourth roller 10-7 starts to move along the inclined surface of the fifth guide plate 10-8 under the drive of the eighth motor 10-2. The fourth roller 10-7 separates from the inclined surface of the fifth guide plate 10-8. At this time, the first push rod 10-6 is located inside the return sample track 4, and continues to move horizontally under the drive of the eighth motor 10-2 until the sample rack 12 is pushed out. Then, the first push rod 10-6 returns to the initial state under the drive of the eighth motor 10-2.

[0098] Embodiment 9

[0099] Based on Embodiment 8, the following design can also be adopted in this embodiment: The sixth driving mechanism 10 can use two motors to respectively control the first push rod 10-6 to extend into or retract from the return sample track 4 and move along the length direction of the return sample track 4.

[0100] In Embodiments 8 and 9, corresponding first optocoupler stoppers 10-10, second optocoupler stoppers 10-11, first optocouplers 10-12, and second optocouplers 10-13 can be provided on the fifth X-axis mounting plate 10-1. The initial state of the first push rod 10-6 is determined by the cooperation of the first optocoupler stopper 10-10 and the first optocoupler 10-12, and the final state of the first push rod 10-6 is determined by the cooperation of the second optocoupler stopper 10-11 and the second optocoupler 10-13.

[0101] Embodiment 10

[0102] From Figure 11 It can be seen that the seventh driving mechanism 11 is located at one end of the conventional sample track 2, the emergency sample track 3, and the return sample track 4 to enable the sample rack 12 to move from the conventional sample track 2 / emergency sample track 3 to the return sample track 4, or from the emergency sample track 3 to the conventional sample track 2.

[0103] The seventh driving mechanism 11 includes a ninth motor 11-2 fixedly assembled on a first base 11-1, a sixth synchronous belt transmission mechanism 11-3 drivingly connected to the output end of the ninth motor 11-2, and a third connecting plate 11-4 fixedly connected to the sixth synchronous belt transmission mechanism 11-3. A second base 11-5 is connected to the third connecting plate 11-4. A third base 11-8 is fixed beside the second base 11-5. First left guide plates 11-6 and second right guide plates 11-7 are fixedly connected to both the second base 11-5 and the third base 11-8. The first left guide plates 11-6 and the second right guide plates 11-7 form a sample rack moving channel, which is slightly wider than the sample rack 12. A second connecting plate 11-9 is connected to the third base 11-8. The second connecting plate 11-9 is connected to the first base 11-1 by a spring. The second base 11-5 can move back and forth on the conventional sample track 2, the emergency sample track 3, and the return sample track 4.

[0104] Working principle of the seventh driving mechanism 11: In the initial state, the second base 11-5 returns to the origin first under the drive of the ninth motor 11-2, and then moves to the position aligned with the conventional sample track 2. The third base 11-8 is always aligned with the return sample track 4. When a sample rack 12 on the emergency sample track 3 / conventional sample track 2 needs to move to the return sample track 4, the second base 11-5 moves to the corresponding aligned track position under the drive of the ninth motor 11-2. Wait for the sample rack 12 to reach the seventh driving mechanism 11, and the second base 11-5 moves to the position aligned with the return sample track 4 under the drive of the ninth motor 11-2. The original third base 11-8 moves to the outside from the position aligned with the return sample track 4. After the second base 11-5 leaves the position aligned with the return sample track 4, the third base 11-8 returns to the position aligned with the return sample track 4 under the pulling force of the spring.

[0105] Embodiment 11

[0106] On the basis of Embodiment 10, the following design can also be adopted in this embodiment: The seventh driving mechanism 11 can use two motors to separately control the movement of the second base 11-5 and the third base 11-8 between the conventional sample track 2, the emergency sample track 3, and the return sample track 4.

[0107] In Embodiments 10 and 11, a third opto-coupler baffle 11-10, a fourth opto-coupler baffle 11-11, a third opto-coupler 11-12, a fourth opto-coupler 11-13, a fifth opto-coupler 11-14, and a sixth opto-coupler 11-15 can be arranged on the first base 11-1. The initial state of the third base 11-8 is determined by the cooperation of the third opto-coupler baffle 11-10 and the fifth opto-coupler 11-14. The initial state of the second base 11-5 is determined by the cooperation of the fourth opto-coupler baffle 11-11 and the third opto-coupler 11-12. The final state of the third base 11-8 is determined by the cooperation of the third opto-coupler baffle 11-10, the fifth opto-coupler 11-14, and the sixth opto-coupler 11-15. The final state of the second base 11-5 is determined by the cooperation of the fourth opto-coupler baffle 11-11, the third opto-coupler 11-12, the fourth opto-coupler 11-13, and the fifth opto-coupler 11-14.
