Tube End Inspection

Product Description

By looking at the glass tubes from the ends after cutting, outside and inside diameter, wall thickness, out-of-round, siding and ovality can be measured with accuracies down to 5 microns. In addition chips, cracks, end shape glazing thickness, tube length and bow can be measured by applying more cameras. Hereby defective and off-spec tubes can be rejected before packing.

JLI vision’s latest generation tube end inspection system satisfies the demand for high-precision inspection which is required in e.g. the solar industry.

The vision system can measure dimensions like OD, ID, WT, out-of-round and siding with an accuracy of 5 microns. The fuse dimensions as well as chips, cracks and end shape irregularities can also be measured together with the tube length and bow. As an add-on the system can be equipped with cameras for measuring shoulder-dimension on end formed tubes.

The system is modular and can be mounted on existing conveyors. Because measurements are done in-line in sync with the conveyor movement, tube handling is very limited and the only modification to the conveyor is to add a “star wheel” or a similar mechanism. A reject device is connected to the system, and statistical information will be available for process control equipment etc.
