Abstract
Abstract 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).

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
220 words
An apparatus for placing electronic and/or electrical components on a substrate comprising a first carriage movable in an X direction, a second carriage guided on said first carriage and movable in a Y direction at right angles to the X direction, the X and Y directions defining an X-Y plane, a number of pick-up devices carried on said second carriage, each pick-up device being capable of picking up a component, a first supporting beam fixedly connected to said second carriage, said supporting beam having a number of rotatable platforms, a transmission common to said number of rotatable platforms for providing rotary movement thereto, each rotatable platform being provided with an operable locking mechanism by which an associated pick-up device can be locked to an associated one of said platforms, a second supporting beam on said second carriage, said second supporting beam being movable at right angles to the X-Y plane and having a number of recessed parts, each of said recessed parts being adaptable to receive a pick-up device, and locking means whereby an associated pick-up device can be locked to an associated recessed part whereby said pickup devices can be moved to the first supporting beam by the second supporting beam so as to be positionable by the first supporting beam and then reconnected to the second supporting beam.
Claim 2
Independent Claim
220 words
An apparatus for placing electronic and/or electrical components on a substrate comprising a first carriage movable in an X direction, a second carriage guided on said first carriage and movable in a Y direction at right angles to the X direction, the X and Y directions defining an X-Y plane, a number of pick-up devices carried on said second carriage, each pick-up device being capable of picking up a component, a first supporting beam fixedly connected to said second carriage, said supporting beam having a number of rotatable platforms, a transmission common to said number of rotatable platforms for providing rotary movement thereto, each rotatable platform being provided with an operable locking mechanism by which an associated pick-up device can be locked to an associated one of said platforms, a second supporting beam on said second carriage, said second supporting beam being movable at right angles to the X-Y plane and having a number of recessed parts, each of said recessed parts being adaptable to receive a pick-up device, and locking means whereby an associated pick-up device can be locked to an associated recessed part whereby said pickup devices can be moved to the first supporting beam by the second supporting beam so as to be positionable by the first supporting beam and then reconnected to the second supporting beam.
Claim 3
Dependent Claim
77 words
An apparatus as claimed in claim 1, wherein at least some of said pick-up devices have ducts in them and wherein at least some of said recessed parts are provided with a number of ducts which can be connected to a source of compressed air and which open out of the inner side of their associated recessed part and can cooperate there with ducts in an associated one of said at least some of said pick-up devices.
Claim 4
Dependent Claim
113 words
An apparatus as claimed in claim 2, wherein each of the pick-up devices is provided with a central part having at least one pair of gripper jaws which can be moved towards and away from each other, said central part being enclosed in a housing and being provided with a two-sided flange arranged at right angles to said housing and with a pressure member subjected to spring force, said flange being disposed between an edge of said housing and said pressure member, said housing being provided with ducts through which air under pressure can be introduced between the two sides of the flange and the edge of the housing and the pressure member.
Claim 5
Dependent Claim
39 words
An apparatus as claimed in claim 1, wherein said transmission includes an electric motor, a pin and a part common to all said platforms, said pin being connected to said motor and arranged to pivotably move said common part.
