[0035] The slide rail 5 has a track 6 on its lower side, and the slide rail 5 slides on the outside of the track 6. A cuboid 3 is fixedly provided on the lower end face of the track 6.

[0037] Working principle and process of a three-axis module pipette with anti-drip buffer structure:

[0038] This pipette achieves movement via a three-axis module, featuring anti-drip and buffer functions. A pressure sensor 9 monitors the internal pressure, ensuring accuracy and stability during pipetting. A power unit 4 provides power to the entire system. Driven by the power unit 4, the moving device 25 begins operation, causing the fixed concave plate 8 to slide on its outer side. Since the pipette fixing device 7 is fixedly connected to the fixed concave plate 8, it moves along with the moving device 25. A slide rail 5 slides outside a track 6, which is fixed to a cuboid 3. The cuboid 3 is fixed to the fixed platform 1 via a fixing body 2. Through the cooperation of the slide rail 5 and the track 6, the pipette can move precisely in the horizontal direction to reach the designated pipetting position. This three-axis module design... This design ensures the pipette can move flexibly in three-dimensional space to meet different pipetting needs. Once the pipette is moved to the designated position, the pipetting device 19 begins the pipetting operation. The lower end face of the pipette tube 20 is in contact with the pipetting head 21. The sealing ring 22 on the outside of the pipetting head 21 ensures a tight seal during the pipetting process, preventing liquid leakage. The pressure sensor 9 plays a crucial role in the pipetting process. The pressure sensor 9 detects changes in air pressure inside the pipette tube 20 through the monitoring head 11 on the lower rear side. The rubber sealing ring 12 on the outer rear side of the monitoring head 11 further enhances the sealing performance of the detection. The detected air pressure data is transmitted to the display screen 13, allowing the operator to monitor the air pressure inside the pipette tube 20 in real time. Simultaneously, the pressure sensor 9 connects to the control system interface 1. Connected to the control system, the system can precisely control the pipetting process based on air pressure data to ensure accuracy. During pipetting, the air pressure sensor 9 monitors the air pressure inside the pipetting tube 20 in real time. If the air pressure is abnormal after pipetting is complete, it may cause liquid leakage. In this case, the air pressure sensor 9 will transmit an abnormal signal to the control system, which can take corresponding measures, such as adjusting the air pressure or stopping the pipetting operation, to prevent liquid leakage. The sealing ring 22 on the outside of the pipetting head 21 and the rubber sealing ring 12 at the rear end of the monitoring head 11 also play a role in preventing leakage. They seal the liquid from the positions of the pipetting head 21 and the monitoring head 11, respectively, reducing the possibility of liquid leakage. During the operation of the pipetting device 19, leakage may occur. Impact and vibration occur when the slider device 23 slides on the slider body 24. When impacted, the impact heads 18 on both sides of the upper end face of the slider device 23 are subjected to force. The impact heads 18 are connected to the small hydraulic buffer body 15 through the piston rod 17. The spring 16 inside the small hydraulic buffer body 15 can absorb the impact energy and play a buffering role. The spring 16 is fixed to the inside of the impact head 18. When the impact head 18 is impacted, the spring 16 is compressed, converting the impact energy into the elastic potential energy of the spring 16, thereby reducing the impact on the pipette device 19, protecting the pipette components, and extending its service life. The small hydraulic buffer body 15 is fixed to the pipette fixing device 7 through the rectangular plate 14, ensuring the stability of the buffer device. In summary...This three-axis modular pipette with a drip-proof buffer structure achieves precise three-dimensional movement via a moving device 25. A pressure sensor 9 monitors the air pressure to ensure pipetting accuracy and prevent dripping. Simultaneously, a small hydraulic buffer body 15 absorbs impact energy, providing a buffering function and improving the pipette's performance and reliability.
