Inspection Method
A high-definition camera combined with a 360-degree sidewall optical lens is used to capture images of the sealing area sidewall.
The system first locates the bottle cap position precisely and creates a circular inspection region along the sidewall edge within the image. When sealing defects are present, obvious grayscale variations appear inside this circular region. By analyzing the grayscale fluctuation level, the system applies a threshold value. Products exceeding the set threshold are identified as defective and automatically rejected.
Installation Conditions
The conveyor system must use a single-lane chain-type structure with a total length of 1.8 meters.
Within the inspection section, the bottle neck area should remain stable, clean, and free from vibration or water droplets, since these conditions may reduce camera inspection accuracy.
The inclination angle of the inspection conveyor shall not exceed 20°, and containers must maintain a spacing of 3–5 mm during conveying.
If bottle neck vibration is observed in the inspection zone, a clamping device with a width of 60–80 mm should be added to improve bottle stability and ensure consistent inspection performance.
