If so, go to S6. Otherwise, the alarm module is triggered, the control system controls the equipment to stop running, and notifies the staff to check and make corresponding adjustments. S6, filter element and pipette tip coaxial detection step: after the filter element and the pipette tip are in place, the detection module performs a coaxial detection on the filter element and the pipette tip. If the alignment is successful, go to S7; if the alignment fails, the control system controls the slider to automatically adjust and detect again until the filter element and the pipette tip are coaxial and then go to S7; if the alignment fails for more than five times, the alarm module is triggered, the control system controls the equipment to stop running, and notifies the staff to check and make corresponding adjustments; S7, filter element pushing step: start the push rod device (7) to push the filter element into the pipette tip. After the push rod device (7) is executed, retract the push rod and ensure that the filter element in the pipette tip is completely assembled, and the slider is reset; S8, the step of continuing to convey the pipette tip: after the filter element is assembled, the control system controls the moving structure (5) to descend and put the pipette tip back to the original position of the second conveying device (4), so that the assembled pipette tip continues to be conveyed through the second conveying device (4) until it is conveyed to the finished product collection frame (8) and is collected in the finished product collection frame (8); S9, loop S3-S7; S10, abnormality detection step: during the assembly process, if an abnormality or equipment failure occurs, the alarm module promptly transmits a signal to the control system and controls the equipment to stop running, and issues an alarm to remind the staff to perform maintenance; S11, assembly completion step: when all the pipette tips have successfully completed the filter element assembly and are transferred to the finished product collection frame (8), the control system controls the equipment to automatically stop working, enter a standby state, and prepare to start the next production cycle; S12. Equipment cleaning and maintenance steps: Clean and maintain the equipment regularly to ensure assembly accuracy and long-term stable operation of the equipment.

7. The assembly method of the filter element assembly equipment according to claim 6, characterized in that: In S7, the push rod device (7) is provided with a detection unit for detecting the push rod device (7), and the detection method includes: S71, push rod initialization test: when the device is started, the push rod device (7) performs a self-test to ensure that the push rod can move smoothly and confirm its initial position; S72, real-time monitoring of push rod movement: The sensor monitors the working status of the push rod in real time to ensure that the push rod can push the filter element into the pipette tip according to the set trajectory. If the push rod is detected to be abnormal or loses power, the control system immediately controls the equipment to stop operating and triggers an alarm; S73, push rod in place detection: when the push rod is executed, the sensor detects whether the push rod has accurately reached the predetermined position to ensure that the filter element has been completely pushed into the pipette tip; S74, push rod pressure detection: Set a pressure sensor to detect whether the force applied by the push rod on the filter element is within a safe range to prevent assembly failure due to excessive or insufficient pressure; S75, push rod reset detection: After the push rod completes the assembly work, the sensor confirms whether the push rod is reset to the initial position to ensure that the equipment is in a ready state and can smoothly proceed to the next assembly.
