Abstract
Description
technical field
[0001] The invention relates to a positioning device, in particular for handling electrical components, having two parallel guide rails defining a guide plane and bearings guided linearly displaceable thereon, to which positioning units are fastened. Background technique
[0002] EP 0962125 B1 discloses a one-sidedly guided and driven elongated positioning arm, in which the oppositely arranged free projecting end can oscillate without damping, so that a correspondingly highly dynamic positioning process is delayed by a damping period. This positioning arm requires at least 3 bearing or support elements. In order to reduce such transient oscillations, such a positioning arm must have the greatest possible bending stiffness, which increases its own weight and increases the driving or braking power when acceleration is required.
[0003] US Pat. No. 5,002,448 A discloses a positioning arm guided on both sides, in which the connection axis runs perpendicular to ...

Embodiment Construction
[0026] FIG. 1 shows the main functional unit of a equipping device with two equipping areas for substrates 4 arranged one behind the other in the transport direction x and with component transport mechanisms 7 arranged on their sides, which transport mechanisms have The components 14 aligned in the transport direction x are removed from the position 8 .
[0027] Above the two installation areas and the removal position 8, there are two slightly longer first positioning arms 1 oriented in the transport direction x, which can each be guided by a corresponding coil part 9 of a linear motor on mutually parallel stationary guide rails. 6 moves. The guide rail 6 in the form of a track extends obliquely with respect to the conveying direction in a first transverse direction y'. The first positioning arm 1 is guided at each end by means of a bearing 5 without play in one of the rail-shaped guide rails 6 .
[0028] The bearing 5, for example composed of a ball circulating element, ha...
