High-speed & high-precision steel pipe threaded joint foreign matter inspection device
It is a device that performs high-speed foreign object inspection of threaded joints such as steel pipes in various thread shapes.
This device is designed for the internal inspection of cylindrical workpieces with dimensions ranging from φ160 to φ300 × L400 mm. It is equipped with five cameras arranged around the circumference, allowing for a 360° inspection of the interior through a process of forward inspection, rotation, and return inspection. The inspection is conducted simultaneously with all five cameras moving at a speed of 500 mm/s while capturing images at a pitch of 10 mm (representative value), enabling real-time judgment. The system performs inspections from start to judgment output in approximately 5 seconds (for L400 mm). 【Features】 ■ 360° Imaging: Inspections can be conducted around the entire circumference without blind spots using multiple cameras. ■ High Precision Judgment: The minimum detectable size of foreign objects is φ0.5 mm. ■ High-Speed Inspection: Scanning at 50 mm/s, real-time judgment, and simultaneous image storage. *For more details, please refer to the PDF document or feel free to contact us.
