Overview

　　The Guanshentai Stool Sample Tube Automatic Assembly Machine is specialized equipment designed for the automated assembly of stool testing/collection tubes. Integrating automatic tube body feeding, sealing ring assembly, sampling rod insertion, cap screwing/pressing, and finished product inspection and unloading, the system achieves a one-stop automated assembly process—transforming bulk components into finished tubes at speeds of 1,200–2,400 units per hour—effectively replacing traditional manual assembly lines.

　　Key Advantages:

　　Precision Sealing Ring Assembly: Utilizes a mechanism combining a tapered guide sleeve and expanding grippers to uniformly expand the O-ring into the cap's sealing groove before precisely releasing it into place. With an assembly accuracy rate exceeding 99.9%, it ensures the ring is fully seated without twisting or rolling, guaranteeing leak-proof performance during transport and use.

　　Precision Sampling Rod Insertion: Employs servo drives and high-precision linear modules to insert the sampling rod vertically into the cap's internal slot to a preset depth (accuracy ±0.3mm). Accurate positioning and insertion prevent tilting, detachment, or excessive insertion depth that could damage the internal preservation fluid pouch.

　　Automatic Cap Screwing: Equipped with a servo-driven capping mechanism allowing independent setting of torque and rotation angles. This ensures the cap is securely tightened—preventing looseness or stripped threads—and creates an effective seal between the internal ring and the tube mouth. Real-time torque monitoring and over-torque alarm protection prevent issues such as tube breakage from overtightening or difficulty for the end-user in opening the tube.

　　Jam-Free Flexible Conveying: Tube bodies and caps are sorted via vibratory bowls and fed through tracks designed to prevent jams. Optimized clearances and auxiliary directional airflow eliminate component pile-ups, ensuring a continuous and stable supply.

　　Multi-Point Inspection and Rejection: Integrates checks for missing sealing rings, correct sampling rod placement, and capping torque. Anomalies at any station trigger automatic rejection of defective units, ensuring a high finished product pass rate.

　　Broad Material Compatibility: Compatible with stool collection tube components made from various plastics such as PP, PE, and PS. By simply swapping out vibratory bowl tracks, assembly jigs, and capping molds, the system can rapidly adapt to different product specifications (tube diameters of 15–30 mm and lengths of 50–120 mm).

　　Clean-Room Compatible Design: The machine features an SUS304 stainless steel frame and transparent protective enclosures. The assembly zone meets clean-room standards, allowing for operation within Class 100,000 clean-room environments. Critical contact components utilize non-metallic, flexible materials to prevent scratching the tube walls during assembly.

　　User-Friendly Operation: Equipped with a PLC and touchscreen HMI, the system offers real-time monitoring of the entire production line. Key parameters—such as capping torque and insertion depth—can be precisely configured, and multiple product recipes can be saved for quick, convenient changeovers. General operators can run the machine after minimal training.

　　Application Scenarios:

　　Ideal for large-scale, standardized assembly in sectors such as In Vitro Diagnostics (IVD) consumables (sampling tubes for fecal occult blood, fecal DNA, and gut microbiota testing), general medical consumables (routine stool analysis and parasite detection tubes), and animal disease testing (sampling tubes for pet and livestock/poultry fecal analysis). With its high-efficiency, precision, and clean automated assembly capabilities, the Guanshentai automatic stool collection tube assembly machine empowers IVD manufacturers to achieve high-quality, mass-scale production and delivery of stool sampling tubes.
