ABSTRACT:
An apparatus for automatic equipping of printed circuit boards with components includes at least two conveying elements arranged at a distance relative to one another along an endless drive. The conveying elements, which are preferably nipper-shaped grabbers, take the components from delivery devices in retrieving positions and conveys them to a transfer position at which they are transferred to an equipping head. The distances between the conveying elements on the endless drive is such that every retrieving position and every transfer position is approached independently of one another under the control of a programmed controller. Stretching of the endless drive, thus, does not deteriorate the exact approach of the retrieving positions and transfer positions.
