Abstract
An optical check for electrical components on an equipping head is provided by moving the suction pipette of the equipping head with the component affixed thereto passed a line sensor that is parallel to the axial direction of the suction pipette. The free end of the suction pipette and the component proceed into the sensor region. The sensor values for the empty suction pipette are compared in an evaluation unit to sensor values of the suction pipette equipped with the component. The presence of the component and/or the height of the component and/or the length of the component are determined by the comparison.
