ABSTRACT:
In the automatic equipping of, for example, printed circuit boards with components, the problem of the unknown position of the component legs occurs. According to the invention, the positions of the component legs in a component picked up by a gripper are measured by a sensor immediately before plug-in. This sensor is essentially composed of two independently horizontally movable perforated plates, each including an infrared emitting diode which emits onto a stationary position photodiode situated therebelow. The measured result can be employed for the positional correction or for the rejection or acceptance of the component.
