Abstract
The position recognition of components placed on substrates has hitherto ensued visually outside the automatic equipping unit. This is complicated and the components lying at the bottom cannot be seen given placement of a number of components above one another. In the method disclosed herein, the position of the placed components in the automatic equipping unit is identified shortly after the actual placement process with a position sensor located in the automatic equipping unit. As a result, errors are recognized early and the automatic equipping unit can therefore be more easily adjusted in view of the positional precision. A camera with a following image evaluation unit is employed as the position sensor.
