The High Speed 2D/3D profile laser sensor can be used for an inline inspection, which detects even the slight bulge, recess or other surface defect that may affect the performance of the tyre.

Three scanCONTROL 2800 2D/3D laser profile sensors from Micro-Epsilon can be used on a test rig which inspects individual tyres in less than one second, enabling to carry out 100% inspection of tyres from its production line. The three sensors inspect the three sides of the tyre walls for defects, taking measurements in real time.

Rather than using multiple laser-based point sensors or capacitive sensors, the scanCONTROL 2800 sensors measure the profile of the tyre using a non-contact laser line, on which multiple measurement points (up to 250 per second) can be acquired and analysed.

With laser point or spot sensors, not only would multiple sensors have to be used to acquire the same surface defect data, but the sensors could not cope with the high throughput rates of tyres on the test rig. The sensors also had problems with the reflection properties of newly-produced, black, shiny rubber tyres.

The scanCONTROL 2800 sensor has an integrated, highly-sensitive CMOS array, which enables measurements of any shiny, reflective or transparent surface, independent of the reflection from the target.

This means perfect accuracy, resolution and reliability are achieved, even at high measurement speeds. Using special software algorithms, logos and symbols on the tyre can be removed from any analyses of the acquired data.

A line optical system projects a laser line onto the surface of the object to be measured.

The back scattered light from the laser line is registered on the CMOS matrix by a high quality optical system.

Along with distance information (z-axis), the controller also calculates the true position along the laser line (x-axis) from the camera image and outputs both values in the sensor’s 2D coordinate system. A moving target or a traversing sensor generates a 3D representation of the object being measured.

Potential applications for scanCONTROL 2800 include contour measurement, robot guidance, door gap alignment, position measurement, rail profile, groove measurement, co-planarity measurement and flatness measurement.

The scanCONTROL 2800 is available in Australia and NewZealand from Bestech Australia .
