Abstract: The invention relates to a component placement machine with a frame (21), a robot (26), a transport system (22) for transporting carriers (23), a placement head (28) for placing components which is fastened to an arm (27) of the robot, a component imaging device (30) also fastened to the arm of the robot, and an imaging device (32) for a carrier. According to the invention, the imaging device (32) for the carrier is fastened to the same arm (27) on which also the imaging device (30) for the component and the placement head (28) are present, in order to increase the placement accuracy.

Abstract: A transport device for carriers (43,45,47) which can be coupled with a follower element (9) displaceable in two orthogonal transport directions (X,Y) by means of centering members (49,51) secured on the follower element, the carrier (43,45,47) is pivotable together with a guide (75,77) about an axis of rotation (71) parallel to one of the transport directions (X,Y) and is thus decoupled from and coupled with the centering members (49,51). The transport device may be used more particularly for plate-shaped carriers, but also for carriers provided with two parallel and straight guiding edges.

Abstract: A rod magazine for electrical and/or electronic components, more particularly for air coils, comprising a rod-shaped holder comprising a magazine chamber of U-shaped cross-section and a component support needle cantilevered from the holder at one needle end and extending freely through the magazine chamber throughout its length.

Abstract: A gripping device for an apparatus for placing electronic and/or electrical components on a substrate comprises a pair of grippers (1 and 2) which are movable relative to one another by compressed-air or vacuum to close and open the jaws (4 and 5) of the grippers. For indicating the absence of a component between the gripper jaws when the jaws are closed, an orifice (1) is provided which communicates with a source of compressed air or vacuum at least during the closing movement of the jaws so that air flows through the orifice during this movement. If the jaws are closed to less than a predetermined distance between them which is equal to the width of the smallest component to be handled by the gripping device, the orifice is closed by one (1) of the grippers to interrupt the flow of air through the orifice.

Abstract: A gripping device for an apparatus for placing electronic and/or electrical components, in particular DIL components, on a substrate comprises a pair of grippers (1 and 2) which are movable towards and away from one another to close and open the jaws (4 and 5) of the grippers. To enable the device to handle components of different widths without the risk of damaging the terminal pins of the components, a stop member in the form of a vertically disposed stepped pin 12 is provided between the grippers for abutment by horizontally extending rib-like projections (8 and 9) on the inner sides of the gripper jaws to limit movement of the grippers in the closing direction.

Abstract: A gripping device for an apparatus for placing electronic and/or electrical components with terminal pins on a substrate comprises a pair of grippers (9 and 10) which are movable relative to one another by fluid-pressure operated means to close and open the jaws (12 and 13) of the grippers. The force for driving the pins of a component into the respective holes in the substrate is applied to the component through abutment means which are self-adjustable to accommodate differences in the heights of the components so that the gripper jaws can be brought to a constant level at the pick-up position each time and can be arranged to grip the component over areas which extend to the bottom of the body of the component to facilitate accurate positioning of the terminal pins in relation to the respective holes in the substrate when mounting the component.

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).

Abstract: In an X-ray examination apparatus comprising an image intensifier tube and an optical light distribution system there is included an image field selector, by means of which, using a subbeam diverted from the imaging beam, a measurement field can be selected and by means of which this measurement field or a boundary outline thereof can be projected back into the imaging radiation path. Thus, it is achieved that during an examination stage an indication of the extent and location of a measurement field which is considered to be relevant for controlling the desired exposure for pictures to be produced, can be constantly displayed on the image screen of the television monitor.
