The production of roof tiles places high demands on measurement and testing methods for ensuring constant high product quality. A laser triangulation sensor by Micro-Epsilon, ILD 1800 is used for 3D inspection and for surface assessment.

The Laser-based optical sensor 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 small 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 sensors in the Series ILD 1800 operate with a semiconductor laser of Class 2, no special protective precautions are needed against laser radiation.

Advantages of the laser measurement:

  • Parameters such as surface roughness can be acquired objectively and directly included in the production process
  • The inspection of individual roof tiles in the central laboratory with long waiting periods until the test results are available can be completely omitted
  • The inspection rate is increased substantially
  • Systematically occurring faults are detected within a short time.

The ILD 1800 is available from Bestech Australia in Australia and New Zealand.
