Abstract
On a carriage (43) which is movable in a horizontal direction (X-direction) in an automatic component mounting machine a slide (41) is arranged which is movable vertically (in the Z-direction). The slide (41) carries a plurality of pick-up devices or pipettes (49), which by means of arms (47) are movably mounted in XY-tables attached to the slide. The XY-tables allow that the arms (47) and thus the pipettes can move, during the different movements of the carriage (43) and the slide (41), to different positions which are accurately controllable. Tee carriage can thus fetch components (51) and then have the pipettes (49) in some positions in relation to each other and then, during the displacement of the carriage to the position above a printed circuit board, the pipettes are allowed to be displaced to other positions in relation to each other, which are adapted to the intended places of the components on the printed circuit board. This reduces the total number of movements which the carriage (43) and the slide (41) have to perform and gives a lower total mounting time. The XY-tables can be electric linear n advantageously electrical XY-motors comprising armatures attached to the arm…
