Beschreibung
Zusammenfassung:A component placement unit for placing a component on a substrate, which component placement unit comprises at least one nozzle which is rotatable about a central axis, by means of which a component can be picked up and placed on the substrate. The component placement unit further comprises at least one sensor for determining the orientation of the component relative to the nozzle. At least one optical element is disposed between said sensor and said nozzle. A first focus plane of the optical element at least substantially coincides with the central axis of the nozzle, whilst a second focus plane substantially coincides with the sensor, wherein an image produced by means of the sensor is a contour image of the component.
