The three-dimensional robotic arm 11 is mounted on the top of the machine body 1. The base 12 is rotatably connected to the top of the machine body 1 via a servo motor. The circular turntable 13 is detachably mounted on the top of the base 12. The tube rack 14 is fixedly connected to the bottom of the circular turntable 13. Multiple sets of tube racks 14 are set at the bottom of the circular turntable 13 and are evenly distributed at the bottom of the circular turntable 13. The output end of the three-dimensional robotic arm 11 is equipped with a pair of sample loading heads. During operation, the flow cytometer tube is placed into the tube in the middle of the circular turntable 13. Inside the rack 14, during sample addition, the three-dimensional robotic arm 11 moves, driving the sample addition head on the three-dimensional robotic arm 11 to the appropriate position. The servo motor drives the base 12 and the circular turntable 13 to rotate, adding samples to the flow cytometer tubes in the current workstation respectively. Through the above structure, the servo motor drives the base 12, the circular turntable 13 and the tube rack 14 to rotate, and the sample addition head is set to add samples to the flow cytometer tubes in sequence, forming a sample addition structure. This realizes the function of adding reagents and samples to the flow cytometer tubes, solving the cumbersomeness of manually adding samples and improving the convenience of sample addition.

[0033] like Figure 3 As shown, the locking assembly includes a locking block 2, a guide rod 21, and a first spring 22. The locking block 2 is slidably connected to the top of the base 12 near the circular turntable 13. Multiple sets of locking blocks 2 are arranged on the top of the base 12 and are evenly distributed. One end of the guide rod 21 is slidably connected to the inner wall of the locking block 2 away from the circular turntable 13. The other end of the guide rod 21 is fixedly connected to the inside of the base 12. The first spring 22 is sleeved on the outer wall of the guide rod 21. During operation, the sliding locking blocks 2 move closer to each other, and the locking blocks 2 slide on the outer wall of the guide rod 21, compressing the first spring 22.

[0034] like Figure 3 and Figure 4As shown, the gripping component includes a positioning hole 3, a clamping post 31, and a slot 32. The positioning hole 3 is located in the middle of the circular turntable 13. Multiple sets of positioning holes 3 are evenly distributed in the middle of the circular turntable 13. Multiple sets of clamping posts 31 are installed in the middle of the three-dimensional robotic arm 11 via the gripping component. The slot 32 is located on the sidewalls where the clamping posts 31 are close to each other. During operation, the three-dimensional robotic arm 11 moves the gripping component and the clamping posts 31 closer to the circular turntable 13, and moves the clamping posts 31 into the positioning hole 3. The gripping component moves the clamping posts 31 closer to each other, and the slot 32 is engaged inside the positioning hole 3, gripping the circular turntable 13. Through the above structure, the clamping posts 31 are inserted into the positioning hole 3 in the middle of the circular turntable 13, forming a gripping structure for the circular turntable 13. This achieves the function of gripping and fixing the circular turntable 13, improving the convenience of gripping and moving the circular turntable 13, and reducing the possibility of the circular turntable 13 falling off during gripping.

During operation, the three-dimensional robotic arm 11 moves the fixed frame 4 to a suitable position, starts the first servo motor 41, and drives the rotating frame 42 to rotate, thereby driving the clamping column 31 to rotate to a suitable angle. Through the above structure, the setting of the first servo motor 41 driving the rotating frame 42 and the clamping column 31 to rotate forms a rotating structure of the gripping assembly, realizing the function of driving the clamping column 31 to rotate, improving the convenience of positioning the clamping column 31, and increasing the accuracy of inserting the clamping column 31 into the positioning hole 3.

[0036] like Figure 4As shown, the clamping assembly includes a second servo motor 5, a winch 51, a pull rope 52, a slider 53, and a second spring 54. The second servo motor 5 is fixedly connected to the top of the inner wall of the rotating frame 42. The winch 51 is rotatably connected to the bottom of the inner wall of the rotating frame 42. The winch 51 is fixedly connected to the transmission end of the second servo motor 5. The slider 53 is slidably connected to the bottom of the inner wall of the rotating frame 42. Multiple sets of pull ropes 52 are arranged symmetrically on the bottom of the inner wall of the rotating frame 42. The top of the clamping post 31 is fixedly connected to the bottom of the pull rope 52. One end of the second spring 54 is fixedly connected to the side wall of the pull rope 52 away from the winch 51. The other end of the second spring 54 is fixedly connected to the bottom of the inner wall of the rotating frame 42. During operation, after the clamping post 31 is inserted into the positioning hole 3, the second servo motor 5 is started, and the second servo motor 5 drives... The winch 51 rotates, winding up multiple sets of pull ropes 52. The pull ropes 52 pull the sliders 53 closer together, and the sliders 53 drive the clamping posts 31 closer together, so that the slots 32 are locked inside the positioning holes 3. The second spring 54 is stretched. After the gripping component moves the circular turntable 13 to the appropriate position, the winch 51 is reversed, the pull ropes 52 become loose, and the second spring 54 drives the sliders 53 and clamping posts 31 to reset. Through the above structure, the winch 51 rotates to wind up the pull ropes 52 and drives the clamping posts 31 closer together, forming a clamping structure of the clamping posts 31. This realizes the function of driving the slots 32 to be locked inside the positioning holes 3, improving the stability of the clamping posts 31 when clamping the circular turntable 13, reducing the stability of the circular turntable 13 when transferring, and reducing the possibility of the circular turntable 13 falling off the clamping posts 31.

The centrifugation washing module is a low-speed centrifuge. In use, the sample is placed in the test tube rack, the program is started, the sample loading component inserts the appropriate pipette tip, and reagents and samples are added to the corresponding flow tube. After loading, the clamping component moves the gripping component to grip the sample in the loading component and moves it to the light-protected shaking incubation module for light-protected shaking. After shaking, the sample is moved to the loading area, diluent is added, and after dilution, the sample is gripped to the centrifugation area for centrifugation. The flow is then washed using the washing needle in the centrifugation washing module. After the liquid in the flow cytometry tube is drained and washing solution is added, the preparatory work is completed. The flow cytometry tube is placed in the tube rack 14 in the middle of the circular turntable 13. During sample addition, the three-dimensional robotic arm 11 moves, driving the sample addition head on the three-dimensional robotic arm 11 to move to the appropriate position. The servo motor drives the base 12 and the circular turntable 13 to rotate, adding samples to the flow cytometry tubes in the current station respectively. The sliding blocks 2 move closer to each other, sliding on the outer wall of the guide rod 21. The first spring 22 is compressed, inserting the circular turntable 13 into the top of the base 12. The blocks 2 are released, and the first spring 22 drives the blocks 2 to move closer to the circular turntable 13, inserting the blocks 2 into the circular turntable. Within 13, the base 12 and the circular turntable 13 are connected together; the three-dimensional robotic arm 11 moves the clamping assembly and the clamping column 31 closer to the circular turntable 13, and moves the clamping column 31 into the positioning hole 3.
