Machine Vision Inspection Systems are readily adapted for inspection of precision parts with 360 convex surfaces - such as glass test tubes and other glass products.
Inspection can occur during or after the manufacturing process.
The images shown below are from glass test tubes used in automated chemistry systems. The orifice of each test tube comprises a bead that is approximately 1 mm high and 1 mm wide. The orifices of the test tubes are designed to engage seals in automated chemistry systems. Leaks cannot be tolerated. Therefore, the sidewall of the orifice must be a near-perfect circular cylinder and the top of the orifice must lie in a flat plane.
