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. The portions of the pin that are separated by the step (or steps) have different diameters corresponding to the different widths of component that the device is required to handle, and the pin is coaxially adjustable by fluid-pressure operated means in the form of a piston (15) to bring the portions of the pin selectively into an operative position between the projections on the gripper jaws for engagement by these projections to determine a closed position of the jaws for a particular width of component.
