The production of roof tiles places high demands on measurement and testing methods for ensuring constant high product quality. In the DASTOKON semi-automatic measurement and test system and in the BSPK pilot plant a laser triangulation sensor of the Series ILD 1800 is used for the 3D inspection and for surface assessment.
The laser-based optical sensor ILD 1800-50 is mounted on a rotating, movable fixture. The profile of the roof tile in the longitudinal and transverse directions is acquired by moving along defined measurement lines over the x and y axes in order to check the complex dimensional-conformance specification.
For the roughness measurement the sensor is brought via the z-axis into an optimum distance position to the surface of the roof tile, giving the smallest diameter of light spot. From the large number of measurements, certain measuring points are extracted by appropriate algorithms (40 measuring points per mm) and the roughness determined.
Since optoNCDT operate with a semiconductor laser of Class 2, no special protective precautions are needed against laser radiation.
