Description

Technical Field

[0001] This invention relates to the field of disease detection technology, and more specifically to a disease detection station that facilitates the detection of livestock and veterinary diseases. Background Technology

[0002] An epidemic disease is a general term for a disease that occurs in humans, animals, or plants and is contagious. When an animal dies from an epidemic, veterinarians need to test or study animal carcass samples on an epidemic disease testing platform.

[0003] Patent CN113229815A discloses a veterinary livestock disease detection device, including a cylindrical shell. An operating box is fixedly installed at the upper part of the middle of the cylindrical shell. A pressing plate is movably engaged at the top of the operating box, and a power supply block and a pressure sensor are respectively arranged in the middle and at both ends of the pressing plate. This invention achieves simple and effective blood collection by incorporating a cylindrical shell, operating box, and needle tube. The entire device is manually fitted onto the livestock's tail area, and then the pressing plate is pressed. With the assistance of a delivery device, the previously drawn blood is quickly absorbed into this area and injected into a blood storage device. Subsequent personnel only need to remove the blood for testing. The device fits onto the livestock's tail, an area that is relatively insensitive, so blood collection will not provoke strong resistance from the livestock. Furthermore, the cylindrical design allows for operation by a single person throughout the entire process.

[0004] However, livestock disease testing still primarily relies on blood sampling and analysis. This method is inefficient for large-scale farming operations. Current livestock disease testing processes are fragmented, requiring sample numbering, reagent addition, and centrifugation to be performed in different equipment or areas. This cumbersome process increases the risk of sample confusion. On large-scale farms, these dispersed steps lead to low efficiency, failing to meet the demands for rapid testing of batches of samples. Furthermore, traditional testing equipment lacks precise station switching and clutch control, and its centrifugation operation is not sufficiently targeted or flexible, further impacting testing efficiency and result accuracy. Therefore, we propose a disease testing station designed for convenient livestock and veterinary disease detection to address the problems described in the background. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a disease detection station that facilitates the detection of livestock and veterinary diseases, so as to solve the problems existing in the background art.

[0006] This invention provides the following technical solution: a disease detection station for facilitating the detection of livestock and veterinary diseases, comprising a workbench, a controller and a test tube rack for placing several plastic test tubes are provided on the top of the workbench, a quantitative dropper for adding reagents and an inkjet printer for sample numbering are provided on the upper side of the test tube rack, a turntable is rotatably arranged inside the workbench, and several centrifuge tubes for centrifuging samples are rotatably mounted on the top of the turntable, each centrifuge tube is provided with a work station slot, a grooved wheel mechanism and a drive mechanism are provided on the lower side of the turntable, the grooved wheel mechanism includes a support shaft for supporting the rotation of the turntable, a first motor for providing power and a grooved wheel assembly, the support shaft is rotatably connected to the workbench, the first motor is fixedly connected to the workbench, the first motor outputs power to the grooved wheel assembly, and then drives the support shaft to rotate intermittently to switch the work station of the centrifuge tube, the drive mechanism controls the rotation or stop of the centrifuge tube to assist in the centrifugation of samples.

[0007] The drive mechanism includes a second motor, a suspended ring, several positioning shafts, and a large gear. The second motor and the suspended ring are both fixedly installed inside the worktable. Several positioning shafts are rotatably connected to the upper side of the suspended ring, and small gears are fixedly connected to their lower ends. The output end of the second motor is fixedly connected to one of the small gears. The large gear is rotatably connected to the circumferential surface of the support shaft. Several small gears mesh with the large gear. A set of clutch components for cutting off or connecting the power connection is provided between each positioning shaft and the corresponding centrifuge cylinder.

[0008] Furthermore, each clutch assembly includes a clutch pressure plate and a driven plate. The clutch pressure plate is fixedly connected to the upper end of the positioning shaft, and the driven plate is fixedly connected to the lower end of the centrifuge cylinder. The clutch pressure plate is controlled by an electric clutch pedal, which is electrically connected to the controller.

[0009] Furthermore, the Geneva assembly includes an active Geneva wheel and a driven dial. The active Geneva wheel is fixedly connected to the output end of the first motor, the driven dial is fixedly connected to the circumferential surface of the support shaft, and the upper end of the support shaft is fixedly connected to the turntable.

[0010] Furthermore, the input end of the quantitative dropper is connected to a storage bottle, and several telescopic droppers are provided at the bottom of the bottle. The reagent in the storage bottle is drawn out by the quantitative dropper and the amount of reagent added is controlled. The reagent drips into the plastic test tube through the telescopic droppers.

[0011] Furthermore, a tube cap cylinder is fixedly connected to the top of the workbench, and the tube cap cylinder stores several test tube caps that are compatible with plastic test tubes.

[0012] Furthermore, a second electric slide rail is installed on the side of the inkjet printer, which is connected to the inkjet printer for controlling the raising and lowering of the inkjet printer.

[0013] Furthermore, the top of the workbench is provided with a first electric slide rail, which is used to control the switching of the test tube rack between the quantitative dispensing device and the inkjet printer.

[0014] Furthermore, the quantitative dropper has a built-in flow sensor and an electromagnetic control valve. Both the flow sensor and the electromagnetic control valve are electrically connected to the controller, which sets and adjusts the reagent dropping volume.

[0015] The technical effects and advantages of this invention are as follows: 1. This invention features an inkjet printer, quantitative dispenser, and centrifuge cylinder integrated into the workbench, along with a first electric slide rail to achieve automatic switching of test tube rack positions. This facilitates the integration of the entire testing process—sample numbering, reagent dispensing, and centrifugation—on a single operating platform, eliminating the need for manual sample transfer between multiple independent devices. It avoids sample spillage caused by test tube tilting or collisions during transport and reduces sample contact with the external environment, lowering the risk of contamination. Furthermore, the automatic switching of positions eliminates the need for manual handling of the test tube rack, allowing for continuous pretreatment of multiple samples, making the testing process more seamless and significantly improving overall operational efficiency. This is particularly suitable for multi-sample batch testing scenarios.

[0016] 2. This invention, by incorporating a flow sensor, an electromagnetic control valve, and a second electric slide rail all linked to a controller, facilitates real-time monitoring of reagent flow using the flow sensor and precise control of the dispensing start and stop using the electromagnetic control valve. This enables accurate control of reagent dosage, avoiding uneven reagent dosage caused by differences in manual dispensing techniques, ensuring that the reagent dosage for each sample meets testing standards, and improving the stability and reliability of test results. Simultaneously, the second electric slide rail allows for flexible height adjustment of the inkjet printer, accommodating plastic test tubes of different heights. This eliminates the need for manual adjustment of the test tubes or inkjet printer position, ensuring clear and accurate coding and solving the problem of poor compatibility with traditional fixed-height inkjet printers.

[0017] 3. This invention, by incorporating a Geneva wheel assembly and a clutch assembly, facilitates the precise switching of centrifuge cylinder positions by leveraging the intermittent transmission characteristics of the Geneva wheel assembly. This ensures that each centrifuge cylinder is accurately aligned with the sample pick-up / placement position or the centrifugation working position, improving operational convenience. Simultaneously, the clutch assembly can independently control the rotation and stop of a single centrifuge cylinder. During testing, the centrifuge cylinder to be started can be flexibly selected based on the number of samples, eliminating the need for all centrifuge cylinders to operate synchronously. This avoids energy waste caused by idling and prioritizes the start of the corresponding centrifuge cylinder when there are urgent samples, enhancing the flexibility and targeted nature of the equipment.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The disease detection station for facilitating the detection of livestock and veterinary diseases involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Reference Figures 1-6This invention provides a disease detection table for convenient detection of livestock and veterinary diseases, including a workbench 1. A controller 2 and a test tube rack 4 for holding several plastic test tubes 5 are installed on the top of the workbench 1. A quantitative dispenser 6 for adding reagents and a coding device 8 for sample numbering are installed on the upper side of the test tube rack 4. A turntable 10 is rotatably mounted inside the workbench 1. Several centrifuge cylinders 12 for centrifuging samples are rotatably mounted on the top of the turntable 10. Each centrifuge cylinder 12 has a work station slot 1201. A Geneva wheel mechanism 11 and a drive mechanism 13 are provided on the lower side of the turntable 10. The Geneva wheel mechanism 11 includes a support shaft 1101 supporting the rotation of the turntable 10, a first motor 1102 providing power, and a Geneva wheel assembly. The support shaft 1101 is rotatably connected inside the workbench 1, and the first motor 1102 is fixedly connected inside the workbench 1, outputting power to the Geneva wheel through the first motor 1102. The components then drive the support shaft 1101 to rotate intermittently to switch the working position of the centrifuge tube 12. The drive mechanism 13 controls the centrifuge tube 12 to rotate or stop to assist in centrifuging samples. The drive mechanism 13 includes a second motor 1301, a suspension ring 1302, several positioning shafts 1304 and a large gear 1307. The second motor 1301 and the suspension ring 1302 are both fixedly installed in the workbench 1. Several positioning shafts 1304 are rotatably connected to the upper side of the suspension ring 1302, and their lower ends are all fixedly connected. The output end of the second motor 1301 is fixedly connected to one of the small gears 1303. The large gear 1307 is rotatably connected to the circumferential surface of the support shaft 1101. Several small gears 1303 mesh with the large gear 1307. Each positioning shaft 1304 and the corresponding centrifuge tube 12 are provided with a set of clutch components for cutting off or connecting the power connection.

[0022] In this embodiment, it is important to note that: the workbench 1 serves as the supporting carrier for the entire testing platform, and its surface is treated with an anti-corrosion coating. This ensures the structural strength to support the various functional modules while preventing corrosion of the platform by samples and reagents during the testing process. The controller 2 adopts an integrated design of a touch screen display and a PLC control module, with a built-in testing process control program, enabling centralized control of the electrical components of the device. The test tube rack 4 has evenly spaced circular slots for fitting plastic test tubes 5, and each slot has a silicone anti-slip pad at the bottom to ensure the stability of the plastic test tubes 5 and prevent damage from collisions during handling. The bottom of the slider is fixedly connected to the first electric slide rail 401 with bolts to ensure no offset during station switching. The plastic test tube 5 has a capacity of 5-10 mL and a threaded opening for sealing with the test tube cap 501, preventing sample leakage during centrifugation. The quantitative dispenser 6 uses a pneumatic quantitative control structure with a built-in high-precision flow sensor and electromagnetic control valve. The dispensing volume can be set via the controller 2, avoiding detection errors caused by uneven reagent dosage during manual dispensing. Its top connects to the storage bottle 601 via a quick-connect interface for easy replacement or cleaning. The inkjet printer 8 uses a laser marking module, and the marking content supports custom input, such as sample number, testing date, animal species, etc., to avoid sample confusion. The turntable 10 has a deep groove ball bearing embedded along its circumference for engagement with the bottom shaft of the centrifuge cylinder 12, reducing... The centrifuge tube 12 exhibits low frictional resistance during rotation. It is a cylindrical structure made of aluminum alloy with an anodized wall to enhance wear resistance. Each centrifuge tube 12 contains several arc-shaped workstations 1201 distributed circumferentially. The inner wall of each workstation is lined with a sponge buffer layer to prevent the plastic test tubes 5 from colliding and breaking during centrifugation. A removable dust cover 1202 is provided at the top of the centrifuge tube to close it and prevent dust from falling into the sample during centrifugation. The diameter of the workstation 1201 matches that of the plastic test tubes 5, further securing their position and ensuring that the test tube axis is parallel to the centrifuge tube axis during centrifugation, preventing incomplete centrifugation due to test tube tilt. The Geneva mechanism 11, with its intermittent transmission design, enables precise switching of the centrifuge cylinder 12, unlike the inaccurate positioning caused by continuous rotation in existing technologies. This ensures that the centrifuge cylinder 12 is accurately aligned with the centrifugation operation position or sample pick-up / placement position after each switch. The drive mechanism 13, serving as the power source for the centrifuge cylinder 12, uses a combination of gear transmission and clutch control to achieve independent start-stop control of one or more centrifuge cylinders 12. This overcomes the limitation of synchronous rotation of all centrifuge cylinders in existing centrifugation equipment, allowing for flexible selection of centrifugation units based on the number of samples, reducing energy consumption while improving testing flexibility. The suspended ring 1302 is a ring-shaped metal bracket, fixed to the bottom of the workbench 1 by several stainless steel support rods.After the plastic test tube 5 is placed into the slot of the test tube rack 4, the first electric slide rail 401 moves the test tube rack 4 to directly below the inkjet printer 8. At this time, the second electric slide rail 801 moves the inkjet printer 8 down, gradually approaching the top of the plastic test tube 5 and then stopping. Then the inkjet printer 8 starts printing and numbering. After the numbering is completed, the second electric slide rail 801 moves the inkjet printer 8 up to reset. The first electric slide rail 401 continues to move the test tube rack 4 to directly below the quantitative dispensing device 6. The telescopic dropper 602 of the quantitative dispensing device 6 descends and inserts. Inside the plastic test tube 5, to prevent reagent from dripping onto the tube wall, add the reagent according to the set amount. After the addition is complete, the telescopic dropper 602 rises to reset, and the first electric slide rail 401 drives the test tube rack 4 back to the initial pick-up and put-down position, completing the sample pretreatment. After the sample pretreatment is completed, place the plastic test tube 5 into the work station slot 1201 of the centrifuge cylinder 12, close the dust cover 1202, and drive the active groove wheel 1103 to rotate through the output end of the first motor 1102. Under the transmission action of the active groove wheel 1103, the centrifuge cylinder 12 is driven to rotate. The moving support shaft 1101 rotates intermittently, driving the turntable 10 to rotate synchronously, aligning the next empty centrifuge tube 12 with the sample pick-up / placement position, thus achieving intermittent station switching. After switching, the first motor 1102 automatically stops to avoid positioning deviation caused by continuous rotation of the turntable 10. When the target centrifuge tube 12 is switched to the centrifugation station, the output end of the second motor 1301 drives the fixed pinion 1303 to rotate, and the large gear 1307 to rotate. The large gear 1307 drives several pinions 1303 to rotate synchronously. The centrifuge shaft 1304 rotates, causing the positioning shaft 1304 to rotate. At this time, the controller 2 triggers the corresponding electric clutch pedal, pushing the clutch pressure plate 1305 upwards to engage with the driven plate 1306. The power of the positioning shaft 1304 is transmitted to the centrifuge cylinder 12 through the clutch pressure plate 1305 and the driven plate 1306, causing the centrifuge cylinder 12 to rotate at high speed, thus centrifuging the sample. After centrifugation, the electric clutch pedal resets, the clutch pressure plate 1305 separates from the driven plate 1306, and the centrifuge cylinder 12 gradually stops under inertia.

[0023] The main difference between this embodiment and the prior art lies in the adoption of a fully integrated process and a differentiated centrifugation control structure. Specifically, the three core components—the inkjet printer 8, the quantitative dispenser 6, and the centrifuge tube 12—are integrated on the workbench 1. The first electric slide rail 401 enables automatic switching of the test tube rack 4 between each stage, eliminating the need for manual sample transfer. Simultaneously, the matching tube cap tube 7 facilitates convenient access to the test tube cap 501, forming a closed-loop process of sample placement → numbering → reagent addition → centrifugation. Batch operation via the test tube rack 4 shortens the overall testing cycle and improves work efficiency. The combined design of the grooved wheel mechanism 11 and the clutch assembly achieves precise control of the centrifugation process, allowing for individual sample handling without waiting for all centrifugation to complete. Each centrifuge tube 12 corresponds to a set of clutch assemblies. The controller 2 controls the electric clutch pedal, which can individually connect and disconnect the power connection between the positioning shaft 1304 and the centrifuge tube 12. For example, when only three samples need to be tested, only three sets of clutch assemblies can be activated, while the remaining centrifuge tubes 12 remain stationary, reducing energy consumption compared to traditional equipment and avoiding equipment damage caused by idling.

[0024] The above structure is the main structure of this embodiment, which solves the problems of functional dispersion, frequent sample transfer, cumbersome operation and easy sample confusion. The controller 2, quantitative dispensing device 6, and inkjet printer 8 are existing structures. The specific structure and connection method of the controller 2 connecting and controlling the first electric slide rail 401, quantitative dispensing device 6 and inkjet printer 8 are not described in detail in this embodiment. In addition, the subsequent processing steps after sample detection and the overall shell protection structure of the equipment are also existing technologies. Therefore, this application does not make detailed limitations.

[0025] Reference Figure 6 Each clutch assembly includes a clutch pressure plate 1305 and a driven plate 1306. The clutch pressure plate 1305 is fixedly connected to the upper end of the positioning shaft 1304, and the driven plate 1306 is fixedly connected to the lower end of the centrifuge cylinder 12. The clutch pressure plate 1305 is controlled by an electric clutch pedal, which is electrically connected to the controller 2.

[0026] In this embodiment, it should be specifically explained that: the pinion 1303 and the clutch pressure plate 1305 are respectively fixedly connected to both ends of the positioning shaft 1304, the second motor 1301 is fixedly connected to one of the positioning shafts 1304, and the controller 2 can control the advance and closure of the corresponding clutch pressure plate 1305. During operation, the controller 2 controls the push rod of the electric clutch pedal to extend and push the clutch pressure plate 1305 to engage with the driven plate 1306, thereby connecting the power. The clutch pressure plate 1305 drives the driven plate 1306 to rotate, and finally drives the centrifuge 12 to rotate. Similarly, the clutch pressure plate 1305 can be retracted by the push rod of the electric clutch pedal, and the clutch pressure plate 1305 can be reset and separated from the driven plate 1306 to cut off the power.

[0027] Refer to recommendation 4- Figure 5 The Geneva assembly includes an active Geneva 1103 and a driven dial 1104. The active Geneva 1103 is fixedly connected to the output end of the first motor 1102, and the driven dial 1104 is fixedly connected to the circumferential surface of the support shaft 1101. The upper end of the support shaft 1101 is fixedly connected to the turntable 10.

[0028] In this embodiment, it should be specifically noted that during operation, the first motor 1102 drives the active groove wheel 1103 to rotate at a constant speed, and the active groove wheel 1103 drives the driven dial 1104 to rotate. It should be noted that the driven dial 1104 has the same number of radial grooves. When the active groove wheel 1103 moves the corresponding radial groove, the corresponding centrifuge tube 12 rotates by the same angle, realizing precise switching of the centrifuge tube 12. Unlike gear transmission, there is no need to set up additional photoelectric sensors or limit switches, which simplifies the structure and reduces the risk of failure. It is easy to adapt to the automation program of the controller 2 and realize continuous batch operation of sample picking and placing, station switching and centrifugation.

[0029] Reference Figures 2-3 The quantitative dropper 6 has a liquid storage bottle 601 connected to its input end, and several telescopic droppers 602 are provided at its bottom. The quantitative dropper 6 draws out the reagent from the liquid storage bottle 601 and controls the amount of reagent added. The reagent drips into the plastic test tube 5 through the telescopic droppers 602. The quantitative dropper 6 has a built-in flow sensor and an electromagnetic control valve. Both the flow sensor and the electromagnetic control valve are electrically connected to the controller 2, and the reagent addition amount is set and adjusted by the controller 2.

[0030] In this embodiment, it is important to note that: the storage bottle 601 is used to store the test reagents and is connected to the input end of the quantitative dropper 6 via a pipeline to provide a reagent source for the dropper; the telescopic dropper 602 at the bottom of the quantitative dropper 6 corresponds to the plastic test tubes 5 on the test tube rack 4, ensuring that the reagents are accurately dropped into the test tubes; the flow sensor built into the quantitative dropper 6 can monitor the reagent flow rate in real time, and the electromagnetic control valve is responsible for controlling the extraction and discharge of the reagents. Both are connected to the controller 2. During operation, the required reagent addition amount is set through the touch interface of the controller 2, and the controller 2 will send a signal to first control the electromagnetic control valve to open, allowing the quantitative dropper 6 to extract the reagents from the storage bottle 601, and the flow sensor synchronously provides feedback on the extraction amount; when the set value is reached, the controller 2 controls the electromagnetic control valve to switch, and the reagents are dripped into the plastic test tubes 5 through the telescopic dropper 602. The entire process requires no manual operation and can simultaneously add reagents to multiple plastic test tubes 5, adapting to the needs of batch sample testing.

[0031] Reference Figure 4 The top of the workbench 1 is fixedly connected to a tube cap cylinder 7, which stores several test tube caps 501 that are compatible with plastic test tubes 5.

[0032] In this embodiment, it should be specifically noted that the tube cap cylinder 7 is a simple cylindrical structure for storing test tube caps 501. It has notches on both sides of the bottom and the test tube caps 501 can be directly placed in the top, making it convenient for operators to take them out at will without having to find a storage location, thus improving sample processing efficiency.

[0033] Reference Figure 2 The side of the inkjet printer 8 is equipped with a second electric slide rail 801, which is connected to the inkjet printer 8 for controlling the lifting and lowering of the inkjet printer 8.

[0034] In this embodiment, it should be specifically noted that: the second electric slide rail 801 is fixed vertically to the side of the controller 2 housing, and its slider is fixed to the side of the inkjet printer 8 by bolts to form a stable transmission connection. By sending a signal through the controller 2, the slider of the second electric slide rail 801 can be controlled to drive the inkjet printer 8 to move up and down. Without the need to manually adjust the position of the test tube or the inkjet printer, the second electric slide rail 801 can drive the inkjet printer 8 to move precisely to the appropriate height to complete the sample numbering. This design avoids the problem of blurry or misaligned inkjet printing caused by height differences, and improves the efficiency and accuracy of numbering.

[0035] Reference Figure 1 The top of the workbench 1 is provided with a first electric slide rail 401, which is used to control the switching of the test tube rack 4 between the quantitative dropper 6 and the inkjet printer 8.

[0036] In this embodiment, it should be specifically explained that when it is necessary to inkjet print a number onto the plastic test tube 5, the first electric slide rail 401 moves the test tube rack 4 to directly below the inkjet printer 8; after the numbering is completed, the first electric slide rail 401 then moves the test tube rack 4 precisely to directly below the quantitative dispenser 6 so that the quantitative dispenser 6 can dispense reagents. The entire process requires no manual intervention, avoiding the problems of test tube tilting and sample spillage that may occur when manually moving the test tube rack, while also reducing the workstation switching time and adapting to the continuous processing needs of batch samples.

[0037] Working principle of the invention: The main problem solved by this embodiment is that, through multi-module integration and automatic station switching design, the functions of inkjet printing, reagent dispensing, and centrifugation are integrated into the workbench 1, and the test tube rack 4 is automatically moved between each station by the first electric slide rail 401. This solves the problems of low efficiency and high risk of contamination caused by the dispersed equipment and manual sample transfer in traditional testing. Through precise electronic control and flexible adaptation design, the flow sensor and electromagnetic control valve realize precise reagent dispensing, and the second electric slide rail 801 adjusts the inkjet printing height and the clutch component controls the start and stop of individual centrifuge tubes. This solves the problems of large errors in manual operation and the inability of the equipment to adapt to different sample specifications and testing needs.

[0038] The specific steps are as follows: S1. Sample preparation and placement: Place the plastic test tube 5 containing the animal sample to be tested, such as blood or tissue fluid, into the slot of the test tube rack 4. S2, Sample Numbering Operation: The height of the inkjet printer 8 is set by the controller 2. At this time, the second electric slide rail 801 drives the inkjet printer 8 to a suitable position 2-3cm away from the test tube opening. Then, the first electric slide rail 401 is controlled to move the test tube rack 4 directly below the inkjet printer 8. The inkjet printer 8 numbers the test tubes with sample numbers, such as sample ID, test date, etc. After the numbering is completed, the second electric slide rail 801 drives the inkjet printer 8 to reset.

[0039] S3. Quantitative addition of reagent: The test tube rack 4 continues to move under the quantitative dropper 6 via the first electric slide rail 401, and the required amount of reagent to be added is set by the controller 2. The electromagnetic control valve built into the quantitative dropper 6 opens and the reagent is drawn from the storage bottle 601. The flow sensor monitors the amount in real time. After the set value is reached, the reagent is accurately dripped into the plastic test tube 5 through the bottom telescopic dropper 602. After the addition is completed, the first electric slide rail 401 drives the test tube rack 4 to reset, the plastic test tube 5 is removed, and the appropriate test tube cap 501 is taken out from the cap tube 7 and screwed onto the mouth of the test tube.

[0040] S4. Sample centrifugation: Place the plastic test tube 5 after adding reagent into the station slot 1201 of the centrifuge tube 12, close the dust cover 1202, and then start the first motor 1102 through the controller 2. Under the transmission action of the groove wheel assembly, the support shaft 1101 and the turntable 10 are driven to rotate intermittently, switching the target centrifuge tube 12 to the centrifugation station. At this time, start the second motor 1301, which drives the positioning shaft 1304 to rotate. Under the meshing action of the large gear 1307, it drives several small gears 1303 to rotate synchronously with the positioning shaft 1304, and controls the corresponding clutch pressure plate 1305 to engage with the driven plate 1306 to connect the power, thereby driving the centrifuge tube 12 to rotate at high speed for sample centrifugation.

[0041] S5. Continuous operation: Repeat steps S1-S4. After centrifugation, disconnect the clutch assembly, open the dust cover 1202 and take out the test tube for subsequent testing.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
