An apparatus for placing electronic and/or electrical components on a substrate, comprising a first carriage which is movable in an X direction and a second carriage which is movable in a Y direction at right angles to the X direction and which carries a number of pick-up devices each capable of picking up a component. A first supporting beam (10) fixedly connected to the Y carriage is provided with a number of rotatable platforms (12) and each of these platforms is coupled via a transmission (36, 38) with a common drive (32) for a rotary movement. Each of the platforms (12) is provided with an operable locking mechanism by which a pick-up device (14) can be locked to each of the platforms (12). The Y carriage further carries a second supporting beam (18) which can move along a guide arranged at right angles to the X-Y plane and has a number of recessed parts (100), each of which is adapted to receive a pick-up device (14), which can be locked therein, in a manner such that each of the pick-up devices (14) can arbitrarily be locked to its associated platform (12) or to the associated recessed part (100). |
