ABSTRACT:
The present invention relates to a method and assembly suited to determining the size and position of a head relative to a clamp when using an industrial multi-axis robot. The invention is based on moving the clamp by means of the robot advantageously past three sensor elements and providing the clamp with a target element suitable for aiding in the position detection of the reference point of the clamp at the instant the clamp moves past a first sensor element. The size and position of the head are determined on the basis of geometrical lines computed from the head edge intercept signals obtained by means of the sensor elements. The lengths of the geometrical lines are determined from the speed of the clamp and the time intervals of intersect instants counted by a control system counter card connected to said sensor elements.
