Abstract: A placement head for automatically placing electronic components on a component carrier. The placement head has a chassis; a first rotor assembly that is mounted so that it is rotatable relative to the chassis about a first axis of rotation and that has a first quantity of first handling devices; and a second rotor assembly that is mounted so that it is rotatable relative to the chassis about a second axis of rotation and that has a second quantity of second handling devices. Each handling device includes a sleeve to which a component holding device for temporarily picking up a component can be attached, and a drive device with a linear drive for moving the sleeve along its longitudinal axis, and a rotary drive for rotating the sleeve about its longitudinal axis. Furthermore, a placement machine with such a placement head and a method for automatic assembly of a component carrier using such a placement head.

Abstract: The invention relates to a camera (130) for detecting objects (192), the camera (130) comprising (a) an illumination device (240) for illuminating an object (192) which is located in an object plane (230a) of the camera (130); and (b) a camera sensor (285) for capturing an image of the object (192) illuminated by the illumination device (240). The illumination device (240) has (a1) a first illumination structure (350) with a plurality of first light sources (351) for illuminating the object (192) with a first illumination light (352) at a first illumination angle; (a2) a second illumination structure (360) having a plurality of second light sources (361) for illuminating the object (192) with a second illumination light (362) at a second illumination angle that is different from the first illumination angle; and (a3) an optical lens array (354) with a plurality of individual lenses (355) for collimating the first illumination light (352) and for collimating the second illumination light (362). Each individual lens (355) is assigned at least a first light source (351) and each individual lens (355) is assigned at least two second light sources (361). The invention further relates to a camera system (125) with two such cameras (130) and an automated placement machine having at least one such camera (130).
