[0002] Sample analyzers are one of the commonly used devices for clinical diagnosis and treatment of diseases. Sample analyzers are divided into blood analyzers, urine analyzers, biochemical analyzers, etc. according to their application types. As the automation of sample analyzers becomes higher and higher, more and more analyzers adopt automatic batch sampling mode. Users place multiple samples on the sample rack, and the sample rack transports the samples in batches to the sample placement position of the analyzer, which can effectively reduce user operations and speed up the detection speed. The existing sample analyzer assembly line usually includes a loading platform for storing samples to be tested, an unloading platform for storing tested samples, and a sample rack transfer device connecting the loading platform and the unloading platform.

[0003] However, existing sample rack transport devices often have complicated transport processes and high transport control requirements. Summary of the invention

[0006] Furthermore, the movable bracket is rotatably connected to one end of the base, and the replacement bracket pushes the movable bracket to rotate when sliding along the base until the movable bracket rotates to the bottom of the replacement bracket. At this time, the movable bracket disengages from the gap and the replacement bracket is located in the gap.

[0007] Furthermore, a reset mechanism is provided on the movable bracket, one end of which is connected to the base and the other end of which is connected to the movable bracket, and is used to reset the movable bracket into the gap when the replacement bracket moves out of the gap.

The synchronous wheel is rotatably connected to the base, the synchronous belt is wound around the synchronous wheel, and the replacement bracket is connected to the synchronous belt. The driving unit drives the synchronous wheel to rotate, and then drives the synchronous belt to move to drive the replacement bracket to slide along the length direction of the base.

[0009] Furthermore, the driving mechanism also includes a guide rail, which extends along the length direction of the base, and the replacement bracket is slidably connected to the guide rail.

[0010] Furthermore, a first protrusion cooperating with the track mechanism is provided on the top of the movable bracket so that the transported object can pass through the gap.

[0011] Furthermore, a second protrusion is provided on the top of the replacement bracket for driving the conveying object to slide along the base.

The technical solutions provided by the embodiments of the present invention are described in detail below in conjunction with the drawings.

[0018] See also Figures 1 to 3 A sample analyzer includes a workbench 6 and a conveying track, wherein the conveying track includes a track mechanism 7 and a track change mechanism 9. The workbench 6 is provided with a sample feeding area 2, a buffer area 4, a recovery area 5, a sampling area 8 and a lever mechanism 1. The sample feeding area 2, the buffer area 4 and the recovery area 5 are arranged in sequence along the length direction of the workbench 6, and the track mechanism 7 extends in sequence along the sample feeding area 2, the buffer area 4 and the recovery area 5. The lever mechanism 1 is arranged at the bottom of the workbench 6 and is used to move the sample rack 3 on the track mechanism 7 between the sample feeding area 2, the buffer area 4 and the recovery area 5. The track change mechanism 9 is used to move the sample rack 3 on the track mechanism 7 to the sampling area 8 for sampling. The sample after sampling is subsequently processed and then detected by a detection mechanism (not shown in the figure). After the sampling is completed, the sample rack is moved to the track mechanism 7 by the track change mechanism 9, and the lever mechanism 1 moves the sample rack to the buffer area 4 and then to the recovery area 5 for recovery. An emergency position 10 is provided at one end of the sample injection area 2 away from the buffer area 4 . A pushing mechanism 11 is provided in the emergency position 10 . The pushing mechanism 11 is used to push the sample rack on the emergency position 10 into the sample injection area 2 .

[0019] See also Figure 3 In the conveying track provided by the present invention, the track mechanism 7 is provided with a gap (not shown in the figure); the track change mechanism 9 includes a base 9-7 and a replacement bracket 9-3 and a movable bracket 9-8 arranged on the base 9-7; in the first state, the movable bracket 9-8 is located in the gap so that the conveyed object can pass through the gap and move along the track mechanism 7; in the second state, the replacement bracket 9-3 slides along the base 9-7 and drives the movable bracket 9-8 to disengage from the gap, so that the replacement bracket 9-3 is located in the gap to move the conveyed object out of the track mechanism 7.

[0020] In the present invention, the movable bracket 9-8 can be driven to disengage from the gap in a manner commonly used in the art, such as: the movable bracket 9-8 can be disengaged from the gap in a sliding manner. Preferably, the following manner is adopted: the movable bracket 9-8 is rotatably connected to one end of the base 9-7, and the replacement bracket 9-3 pushes the movable bracket 9-8 to rotate when sliding along the base 9-7, until the movable bracket 9-8 rotates to the bottom of the replacement bracket 9-3, at which time the movable bracket 9-8 disengages from the gap, and the replacement bracket 9-3 is located in the gap. The above structure can be used to move the sample rack on the track mechanism 7 to the sampling area 8 for sampling. Not only is the structure simple, but it also occupies less space, reducing the assembly and positioning requirements between components.

[0021] Furthermore, the movable bracket 9-8 is provided with a reset mechanism, and after adopting the reset mechanism, the movable bracket 9-8 can be reset without a power device, which has a simple structure and low cost. The reset mechanism is preferably a spring 9-9, one end of which is connected to the base 9-7 and the other end of which is connected to the movable bracket 9-8, and is used to reset the movable bracket 9-8 into the gap when the replacement bracket 9-3 moves out of the gap.

[0022] Furthermore, a driving mechanism is provided on the base 9-7, and the driving mechanism includes a driving unit (not shown in the figure), a synchronous wheel 9-12 and a synchronous belt 9-2. The synchronous wheel 9-12 is rotatably connected to the base 9-7, and the synchronous belt 9-2 is wound around the synchronous wheel 9-12. The replacement bracket 9-3 is connected to the synchronous belt 9-2. The driving unit is preferably a motor. The driving unit drives the synchronous wheel 9-12 to rotate, and then drives the synchronous belt 9-2 to move to drive the replacement bracket 9-3 to slide along the length direction of the base 9-7.

[0023] Furthermore, the driving mechanism also includes a guide rail 9-1, which extends along the length direction of the base 9-7, and the replacement bracket 9-3 is slidably connected to the guide rail 9-1; the guide rail is used to guide the replacement bracket to slide along the base.

[0024] Furthermore, the base 9 - 7 is perpendicular to the track mechanism 7 , so as to facilitate the transport of the sample rack 3 on the track mechanism 7 to the sampling area 8 for sampling.

[0025] For further information, see Figure 3 The top of the movable bracket 9-8 is provided with a first protrusion 9-10 that cooperates with the track mechanism 7 so that the transported object can pass through the gap, and the bottom of the sample rack 3 is provided with a groove (not shown in the figure) that is compatible with the first protrusion 9-10; the combination of the first protrusion and the groove not only has a simple structure but also low cost.

[0026] Furthermore, a second protrusion 9-4 is provided on the top of the replacement bracket 9-3 for driving the conveying object to slide along the base 9-7, and a groove (not shown in the figure) matched with the second protrusion 9-4 is provided on the bottom of the sample rack 3; the combination of the second protrusion and the groove not only has a simple structure, but also the sample rack 3 will not shake when moving on the replacement bracket 9-3, and the operation is more stable.

[0027] Furthermore, a roller 9-5 is provided on one side of the movable bracket 9-8 close to the substitute bracket 9-3. When the substitute bracket 9-3 moves along the length direction of the base 9-7 to push the movable bracket 9-8 to rotate, the roller 9-5 is used to achieve rolling friction to reduce the friction loss of the substitute bracket 9-3 and extend its service life.

[0028] Furthermore, a chamfer 9-11 is provided at the bottom end of the substitute bracket 9-3 close to the movable bracket 9-8, which is beneficial for the substitute bracket 9-3 to push the movable bracket 9-8 to rotate, and at the same time ensures the smooth movement of the substitute bracket 9-3 when switching the movable bracket 9-8.

[0029] During sample introduction, the lever mechanism 1 moves the sample rack 3 on the track mechanism 7 from the sample introduction area 2 to the buffer area 4, and scans the code of the sample rack in the buffer area 4 to obtain relevant information. When it is necessary to sample the sample rack in the buffer area 4, the driving unit (not shown in the figure) drives the replacement bracket 9-3 to move along the length direction of the base 9-7 to push the movable bracket 9-8 to rotate until the movable bracket 9-8 rotates to the bottom of the replacement bracket 9-3. At this time, the spring 9-9 is stretched and the movable bracket 9-8 is disengaged from the gap, so that the replacement bracket 9-3 is located in the gap, and the lever mechanism 1 moves the sample rack to be sampled toward the track change mechanism 9. When the sample rack to be sampled moves to the replacement bracket 9-3, the driving mechanism drives the replacement bracket 9-3 to drive the sample rack to be sampled to move along the base 9-7 away from the track mechanism 7, and moves the sample rack 3 to the sampling area 8 for sampling. When the replacement bracket 9-3 leaves the movable bracket 9-8, the stretched spring 9-9 retracts and the movable bracket 9-8 returns to its original position in the first state in the gap. After the sampling of the sample rack is completed, the replacement bracket 9-3 drives the sample rack to slide along the base 9-7 according to the above method, and drives the movable bracket 9-8 to disengage from the gap, so that the replacement bracket 9-3 is located in the gap, and the lever mechanism 1 is used to move the sample rack on the replacement bracket 9-3 that has been sampled to the cache area 4 to complete the sampling process of the sample rack.

[0030] When there are emergency samples in the emergency position 10, the emergency samples need to be tested first, and the pushing mechanism 11 pushes the emergency sample rack in the emergency position 10 into the sample injection area 2. The lever mechanism 1 moves the emergency sample rack in the sample injection area 2 to the buffer area 4 for code scanning, and drives the replacement bracket 9-3 to slide along the base 9-7 using the aforementioned method, and drives the movable bracket 9-8 to disengage from the gap, so that the replacement bracket 9-3 is located in the gap. After the code scanning is completed, the lever mechanism 1 moves the emergency sample rack to the replacement bracket 9-3, and the replacement bracket 9-3 moves the emergency sample rack to the sampling area 8 for sampling. During the transportation process, the code scanning mechanism is rotated and aligned with the sample identification code on the emergency sample rack on the replacement bracket 9-3 for identification and code scanning. After the sampling, the emergency sample is subsequently processed and then tested by the detection mechanism (not shown in the figure). After the sampling of the emergency sample rack is completed, the replacement bracket 9-3 drives the emergency sample rack to slide along the base 9-7 according to the aforementioned method, and drives the movable bracket 9-8 to disengage from the gap, so that the replacement bracket 9-3 is located in the gap, and the lever mechanism 1 moves the emergency sample rack that has been sampled on the replacement bracket 9-3 to the buffer area 4. If the emergency sample rack does not need to be re-tested, the lever mechanism 1 moves it from the buffer area 4 to the recovery area 5 for recovery. When the replacement bracket 9-3 drives the emergency sample rack to move to the sampling area 8 for sampling, the lever mechanism 1 can move the sample rack on the track mechanism 7 for scheduling. Even if the track change mechanism 9 is processing the sampling work of the emergency sample rack, the track mechanism 7 can still independently complete the scheduling of the sample rack on the track, and perform it synchronously, saving time and improving the working efficiency of the system.
