The ESR (Erythrocyte Sedimentation Rate) tube automatic assembly machine is designed for the automated assembly of ESR tubes—comprising the tube body, sealing stopper/cap, and pre-filled anticoagulant. Integrating automatic multi-component feeding, vacuum-assisted stopper insertion, screw-capping, dosage verification, and finished product sorting, it achieves a fully automated, closed-loop process from loose components to finished goods. This ensures complete component assembly and reliable sealing, fully meeting the rigorous standards for precision and cleanliness required in clinical vacuum blood collection tube manufacturing.
The equipment utilizes multiple precision vibratory bowls or hoppers to feed components such as tube bodies, butyl rubber stoppers, safety caps, and labels. High-speed rotary tables or linear slides facilitate sequential operations—including stopper insertion, cap tightening, preliminary seal testing, and finished product discharge—without requiring manual intervention. It integrates seamlessly with upstream injection molding and downstream packaging/sterilization processes, allowing a single operator to monitor multiple production lines simultaneously.
Built with a high-strength frame and independent servo drive systems, the machine features anti-jamming and error-prevention mechanisms at critical stations. Parameters such as stopper insertion depth and capping torque are digitally controlled, achieving a repeatability precision of ±0.05mm to ensure consistent assembly and eliminate leakage risks. Designed for stable 24/7 operation, the system maintains a defect rate below 0.2%, meeting the demanding delivery requirements of high-volume orders.
Equipped with a PLC and industrial touchscreen, the system stores production recipes for hundreds of tube specifications (diameter, length, anticoagulant dosage, stopper type), enabling one-touch product changeovers. An integrated vision system and pressure sensors monitor for defects—such as improper stopper seating, tilted caps, or sealing anomalies—in real-time; defective units are automatically rejected with accompanying audio-visual alarms. Production data supports MES integration, ensuring full process traceability.
Assembly speeds range from 60 to 100 tubes per minute (depending on component count and process complexity), representing 8–10 times the efficiency of manual assembly. With multi-station parallel processing, daily output easily exceeds 100,000 units, while significantly reducing contamination and microbial risks associated with human contact, thereby cutting overall operating costs by more than 50%. By re-engineering the ESR tube assembly process through automation and intelligent inspection, this automatic assembly machine ensures consistent sealing quality and inspection precision for every tube. Choose this solution to deliver defect-free ESR tubes to the clinical testing frontline, safeguarding the accuracy and reliability of every sedimentation test.
