ABSTRACT:
A placement unit for mounting electric components onto substrates has means for moving perpendicularly to the substrate, a housing, a built-in, rotatable holder for the components, and a rotary drive for the holder mounted within the housing. The holder is connected via an axially elastic coupling to the rotary drive in a manner which is at least temporarily torsionally rigid, wherein the coupling includes a separable coupling having coupling elements arranged to be uncoupled in an axial direction. The holder is pre-stressed axially toward the component against the rotary drive by an adjustable pressure device, wherein the coupling surfaces of the coupling elements form an axial stop for the holder, and wherein the coupling surfaces separate from one another by an axial application force that acts on the holder and prevails over the axial pre-stress.
