Technical Field

[0001] This invention relates to the field of sample processing technology, and in particular to an intelligent sample processing device for auxiliary testing. Background Technology

[0002] In soil sample processing, liquid injection (adding liquid) and liquid-solid mixing (mixing liquid or liquid-solid mixing) are common operations, mainly used to extract target substances (such as pollutants, nutrients, heavy metals, organic matter, etc.), adjust sample conditions (such as moisture content, pH), or carry out chemical reactions (such as digestion, derivatization). These operations are widely used in environmental monitoring, agricultural analysis, geological surveys, and scientific research experiments.

[0003] Currently, sample processing is generally done manually, requiring unified injection followed by sequential mixing. However, a single soil sample typically involves dozens or even hundreds of bags, resulting in a large workload and a heavy burden on staff. Summary of the Invention

[0023] This invention proposes an intelligent sample processing device to assist in experiments.

[0024] like Figures 1 to 3 The intelligent sample processing device for auxiliary experiments shown includes a housing 1, a liquid injection mechanism 2, a liquid mixing mechanism 3, and several receiving racks 4, each of which is used to hold test tubes. A receiving space 11 is provided inside the housing 1. One end of the housing 1 has a sample inlet 12, and the other end has a sample outlet. The receiving space 11 is connected to both the sample inlet 12 and the sample outlet 13. Two slide rails 14 are provided within the receiving space 11, arranged parallel and spaced apart, extending from the sample inlet 12 towards the sample outlet 13. The liquid injection mechanism 2 and the liquid mixing mechanism 3 are both located within the two slide rails 11. Between the slide rails 14, the liquid injection mechanism 2 is located near the sample inlet 12, and the liquid mixing mechanism 3 is located between the liquid injection mechanism 2 and the sample outlet 13; the first sample transfer mechanism 5 and the second sample transfer mechanism 6 are respectively slidably arranged on the two slide rails 14. The first sample transfer mechanism 5 is used to send each container 4 after loading the test tubes from the sample inlet 12 into the liquid injection mechanism 2 along the two slide rails 14 in sequence; the first sample transfer mechanism 5 is also used to send each container 4 that has completed liquid injection in the liquid injection mechanism 2 into the liquid mixing mechanism 3 in sequence; the second sample transfer mechanism 6 is used to send all the containers 4 that have completed liquid mixing in the liquid mixing mechanism into the sample outlet 13.

[0025] The staff places the test tube to be injected into the container 4, then sends the container 4 into the sample inlet 12. The first sample transfer mechanism 5 sends the container 4 into the liquid injection mechanism 2 to complete the liquid injection. Then, the container 4 with the liquid injection completed is sent into the mixing mechanism 3. Finally, the second sample transfer mechanism 6 sends the container 4 with the mixed sample into the sample outlet 13. The staff only needs to set the liquid injection volume of the liquid injection mechanism 2 and send the sample at the sample inlet 12 and take the sample at the sample outlet 13. This realizes intelligent and automated liquid injection and mixing, which effectively speeds up the work efficiency and reduces the workload.

[0026] The receiving rack 4 includes a horizontal frame 41 and two connecting blocks 42, one connecting block 42 being located at one end of the horizontal frame 41 and the other connecting block 42 being located at the other end of the horizontal frame 41; the horizontal frame 41 has several receiving holes 45 (not shown in the figure), and each receiving hole 45 is arranged at intervals along one connecting block 42 toward the other connecting block 42; the first sample transfer mechanism 5 is used to pick up the two connecting blocks 42 and drive the horizontal frame 41 to move along the two slide rails 14. Both the first sample transfer mechanism 5 and the second sample transfer mechanism 6 drive the receiving rack 4 through the two connecting blocks 42 of the receiving rack 4, which facilitates the retrieval of the receiving rack 4 and avoids collisions with the test tubes inside the horizontal frame 41 during sample transfer.

[0027] The two connecting blocks 42 are iron blocks; the first sample transfer mechanism 5 includes a first connecting plate 54, a first driver, two extension plates 51 and two first magnetic chucks 55. The first driver is slidably connected to the two slide rails 14 respectively, and the first driver drives the first connecting plate 54. The first connecting plate 54 extends along one slide rail 14 to the other slide rail 14. One extension plate 51 is located at one end of the first connecting plate 54, and the other extension plate 51 is located at the other end of the first connecting plate 54. One first magnetic chuck 55 is located at one extension plate 51, and the other first magnetic chuck 55 is located at the other extension plate 51. Both first magnetic chucks 55 are located on the side of the first connecting plate 54 away from the sample outlet 13. One first magnetic chuck 55 is used to attract one connecting block 42. The other first magnetic chuck 55 is used to attract the other connecting block 42. The first driver is used to attract adjacent connecting blocks 42 through the two first magnetic chucks 55 respectively, and drive the crossbeam 41 to move along the slide rail 14. The two connecting blocks 42 are iron blocks. The first transfer mechanism 5 grabs the two connecting blocks 42 through two magnetic suction devices, thereby driving the cross frame 41 to move along the two slide rails 14.

[0028] Specifically, each of the two connecting blocks 42 has a plug 43 on the side facing the first magnetic attractor 55; each of the two first magnetic attractors 55 has an insertion port (not shown in the figure) on the side away from the sample outlet, and a pressure sensor (not shown in the figure) is installed at the bottom of the insertion port; the two first magnetic attractors 55 are used to attract the two adjacent connecting blocks 42, so that one plug 43 is inserted into one insertion port and the other plug 43 is inserted into the other insertion port; the pressure sensor is used to detect whether the plug 43 is inserted into the insertion port; the first driver is used to drive the connected receiving frame 4 to move along the two slide rails 14 into the liquid injection mechanism 2 when both pressure sensors detect the insertion of the plug 43. The insertion port and pressure sensor on the magnetic attractor determine whether to grab the receiving frame 4 by detecting whether the plug 43 is inserted, ensuring that the receiving frame 4 enters the liquid injection mechanism 2 correctly.

[0029] The first actuator includes a first mounting plate, a first electrically controlled telescopic column 52, and two first electrically controlled slides 53. The first mounting plate is located between the two first electrically controlled slides 53 and is connected to each of the two slides 53. One of the first electrically controlled slides 53 is slidably connected to one of the slide rails 14, and the other first electrically controlled slide 53 is slidably connected to the other slide rail 14. The first electrically controlled telescopic column 52 is disposed on the first mounting plate, and a first connecting plate 54 is located below the first mounting plate. The output end of the first electrically controlled telescopic column 52 is connected to the first connecting plate 54. The first electrically controlled telescopic column 52 is used to drive the two first magnetic attractors 55 to move vertically up and down through the first connecting plate 54. The two first electrically controlled slides 53 are used to drive the first electrically controlled telescopic column 52 to slide along the two slide rails 14 through the first mounting plate. The first electrically controlled slides 53 drive the two first magnetic attractors 55 to slide along the two slide rails 14 through the first mounting plate, and the first electrically controlled telescopic column 52 drives the two first magnetic attractors 55 to move vertically.

[0030] The second sample transfer mechanism 6 includes a second connecting plate 64, a second driver, and two second magnetic chucks 65. The second driver is slidably connected to the two slide rails 14 and drives the second connecting plate 64, which is parallel to the first connecting plate 54. One of the second magnetic chucks 65 is located at one end of the second connecting plate 64, and the other is located at the other end. One of the second magnetic chucks 65 is used to attract one of the connecting blocks 42 located in each receiving rack 4 within the mixing mechanism 3. The other second magnetic chuck 65 is used to attract the other connecting block 42 located in each receiving rack 4 within the mixing mechanism 3. The second driver is used to drive the two magnetic chucks to slide along the two slide rails 14 via the second connecting plate 64.

[0031] Specifically, the second magnetic chuck 65 is elongated and extends along the extension direction of the two slide rails 14 so as to directly grab all the containers 4 inside the liquid injection mechanism 2.

[0032] The second actuator includes a second mounting plate 61, a second electrically controlled telescopic column 62, and two second electrically controlled slides 63. The second mounting plate 61 is located between the two second electrically controlled slides 63 and is connected to the two second electrically controlled slides 63 respectively. One of the second electrically controlled slides 63 is slidably connected to one of the slide rails 14, and the other second electrically controlled slide 63 is slidably connected to the other slide rail 14. The second electrically controlled telescopic column 62 is disposed on the second mounting plate 61, and the second connecting plate 64 is located below the second mounting plate 61. The output end of the second electrically controlled telescopic column 62 is driven to connect to the second connecting plate 64.

[0033] The injection mechanism 2 includes a track 21, a third electrically controlled slide 22, an injector 23, and a storage tank 24.

The third electrically controlled slide 22 is slidably connected to the track 21 and drives the injector 23. The storage tank 24 is detachably mounted on the side of the third electrically controlled slide 22 away from the two slide rails 14 and is used to store the solution to be injected. A connecting pipe is provided between the storage tank 24 and the injector 23. A water pump is installed in the connecting pipe. One end of the connecting pipe is connected to the storage tank 24, and the other end is connected to the injector 23. The third electrically controlled slide 22 is used to drive the injector 23 to slide along the track 21 so that the injector 23 injects the solution in the storage tank 24 into each test tube on the crossbar 41. The liquid storage tank 24 and the third electrically controlled slide 22 are detachably connected. The staff can change the type of solution in the liquid storage tank 24 according to the actual usage needs, so that the size of the liquid storage tank 24 can be adjusted according to the usage.

[0034] The third electrically controlled slide 22 slides along the track 21 so that the injector 23 injects the solution in the storage tank 24 into each test tube in the container rack 4 in sequence.

[0035] A post 44 is provided below each connecting block 42; the mixing mechanism 3 includes a shaker body 31 and a fixing frame 32. The working position of the shaker body 31 is located at the top of the shaker body 31, and the fixing frame 32 is fixed at the working position; the fixing frame 32 is provided with several limiting hole groups, each limiting hole group being arranged sequentially at intervals along the extension direction of the two slide rails 14; each limiting hole group includes two insertion holes 33, one insertion hole 33 being located near one slide rail 14, and the other insertion hole 33 being located near the other slide rail 14; the fixing frame 32 is also provided with a receiving groove 34, which is located between the two insertion holes 33, and is used to receive the test tubes inside each receiving frame 4. The post 44 and the fixing frame 32 are provided so that the receiving frame 4 is fixed on the shaker body 31.

[0036] Specifically, a pressure plate 35 and a third electrically controlled telescopic column 36 are also provided above the oscillator body 31. Two slide rails 14 are located between the pressure plate 35 and the fixed frame 32. The third electrically controlled telescopic column 36 is located on the side of the pressure plate 35 away from the fixed frame 32, and the third electrically controlled telescopic column 36 drives the pressure plate 35. The third electrically controlled telescopic column 36 is used to control the pressure plate 35 to move towards the fixed frame 32 after the first sample transfer mechanism 5 sends the preset number of container racks 4 into the fixed frame 32, so that the fixed frame 32 and the pressure plate 35 cooperate to clamp and fix each container rack 4. Through the further cooperation of the pressure plate 35, the stability of each test tube during mixing is ensured.

[0037] A sample inlet frame 15 and a sample outlet frame 16 are provided on the outside of the housing 1. The sample inlet frame 15 is located at the sample inlet 12, and the sample outlet frame 16 is located at the sample outlet. Two slide rails 14 extend into the sample inlet frame 15 and the sample outlet frame 16, respectively.

[0038] Specifically, the sample feed rack 15 is provided with a test tube channel and two limiting channels. The test tube channel is located between the two limiting channels. Both the test tube channel and the two limiting channels extend along the extension direction of the two slide rails 14. Both the test tube channel and the two limiting channels are connected to the internal storage space 11 of the shell 1. The test tube channel is used to accommodate each test tube in the crossbar 41. One limiting channel is used to accommodate the insertion post 44 of one of the connecting blocks 42. The other limiting channel is used to accommodate the insertion post 44 of another connecting block 42. A support plate is formed between the test tube channel and the two limiting channels. The two support plates extend along the extension direction of the two slide rails 14. One support plate is used to support the connection between one of the connecting blocks 42 and the crossbar 41. The other support plate is used to support the connection between the other connecting block 42 and the crossbar 41.

[0039] Specifically, the sample inlet rack 15 and the sample outlet rack 16 have the same structure, but the horizontal height of the two support plates in the sample outlet rack 16 is lower than that of the two support plates in the sample inlet rack 15.

[0040] The work process is as follows; The container rack 4 containing each test tube is fed into the sample feed rack 15. Each container rack 4 is arranged in sequence along the extension direction of the two slide rails 14, and the plug 43 of each container rack 4 is set facing the housing 1. Set the parameters for injection mechanism 2 and mixing mechanism 3; The first sample transfer mechanism 5 moves along the two slide rails 14 into the sample inlet rack 15, and uses the two first magnetic suction devices 55 to attract the two connecting blocks 42 of the nearest receiving rack 4, so that the two plugs 43 respectively enter the adjacent sockets to trigger the pressure sensor; then the first sample transfer mechanism 5 moves along the two slide rails 14 to send the connected receiving rack 4 to the position below the liquid injection mechanism 2. The third electrically controlled slide 22 drives the liquid injector 23 to slide along the track 21, sequentially sending the solution in the storage tank 24 into each test tube in the lower container rack 4; The first sample transfer mechanism 5 drives the container 4, which has been filled with liquid, to continue sliding along the two slide rails 14, and sends the container 4 into the fixed frame 32. The first electrically controlled telescopic column 52 drives the two inserts 44 of the container 4, which has been filled with liquid, to insert the two inserts 44 into the two holes 33 closest to the liquid outlet and not inserted. Then the first sample transfer mechanism 5 separates the container 4 that has entered the fixed frame 32 and repeats the above steps until the preset number of container 4 have been filled with liquid and entered the fixed frame 32. The third electrically controlled telescopic column 36 drives the pressure plate 35 to press the preset number of container racks 4 into the fixed frame 32, and then starts the oscillator body 31 to mix the test tubes in the preset number of container racks 4; until the mixing is completed, the third electrically controlled telescopic column 36 drives the pressure plate 35 away from the fixed frame 32. The second sample transfer mechanism 6 moves along the two slide rails 14 to a position above the fixed frame 32, controls the second electrically controlled telescopic column 62 to drive the two second magnetic suction devices 65 to respectively attract all the receiving frames 4 of the fixed frame 32, and sends all the receiving frames 4 into the sample discharge frame 16 along the two slide rails 14.
