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, pre-filled anticoagulant, and other components. It integrates automatic multi-component feeding, vacuum-assisted stopper insertion, screw-capping, dosage verification, and finished product sorting. This system achieves a fully automated, closed-loop process from loose parts to finished products, ensuring complete component assembly and reliable sealing, thereby meeting the rigorous precision and cleanliness standards required for clinical vacuum blood collection tubes.
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 manual intervention. It seamlessly integrates with upstream injection molding and downstream packaging/sterilization processes; a single operator can monitor multiple production lines, significantly reducing staffing requirements and labor intensity.
Built with a high-rigidity cast frame and independent servo drive systems, the machine features anti-jamming and anti-misassembly detection mechanisms at critical stations. Parameters such as stopper insertion depth and capping torque are digitally controlled, achieving a repeatability of ±0.05 mm to ensure consistent assembly quality and eliminate leakage risks. Key drive components undergo wear-resistant and anti-corrosion treatments, enabling stable 24/7 operation with a defect rate below 0.2%, thus satisfying the stringent delivery demands of high-volume orders.
Equipped with a PLC and industrial touchscreen, the system stores production recipes for hundreds of ESR tube specifications (covering tube diameter, length, anticoagulant dosage, and stopper type), allowing for rapid product changeovers with a single command. Integrated vision systems and pressure sensors monitor for defects—such as improper stopper seating, tilted caps, or sealing anomalies—in real-time; defective units are automatically rejected, accompanied by audio-visual alarms. Production data supports MES integration, ensuring full traceability of the assembly process.
The assembly cycle rate ranges from 60 to 100 tubes per minute (depending on component count and process complexity), representing an efficiency 8 to 10 times higher than manual assembly. With multiple stations operating in parallel, this machine easily achieves a daily output exceeding 100,000 units; it simultaneously minimizes contamination and microbial risks associated with manual handling, reducing overall operating costs by more than 50%.
By leveraging automation technology and intelligent inspection to re-engineer the assembly process, this machine ensures consistent sealing quality and inspection precision for every ESR tube. Choose this solution to deliver defect-free ESR tubes to the clinical testing frontline, safeguarding the accuracy and reliability of every sedimentation test.
