摘要： The positioning device comprises a chassis (1) provided with a drive wheel (2), mounted on the shaft of a motor (6), and a reversing wheel (3). The positioning device further comprises a loop-shaped traction member (4) tensioned around the wheels (2, 3). The traction member (4) is connected to a load (5), which is movable relative to the chassis (1) and together with the traction member (4) forms a closed loop. The drive wheel (2) and the motor (6) form a drive means for driving the load (5) via a first section (41) of the traction member (4), which first section is disposed between the load (5) and the drive wheel (2), and via a second section (42) of the traction member (4), which second section is disposed between the load (5) and the drive wheel (2). The load (5) carries tensioning means (7) for tensioning the traction member (4). These tensioning means act on the first section (41) of the traction member (4) via a first point of engagement (A) and on the second section (42) of the traction member (4) via a second point of engagement (B). These tensioning means (7) keep the traction member (4) under tension. The load (5) is coupled to the traction member (4) via a coupling mechanism (8). The coupling mechanism (8) links a first relative movement of the first point of engagement (A) relative to the load to a second relative movement of the point of engagement (B) relative to the load in an opposite direction.

摘要： 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.

摘要： 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.

摘要： 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. The orifice is formed in a body (6) which is fixed in relation to the movements of the grippers and which is formed on two opposite sides with abutment surfaces (7 and 8) which limit the closing movement of the grippers and in one (7) of which the orifice is formed.

摘要： 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. The abutment means comprise a spring-loaded, vertically disposed rod (18) which is movable vertically relative to the gripper jaws (12 and 13) and which abuts the upper side of the body of the component (16) as the gripping device is lowered to the pick-up position. As the gripper jaws close on the component a friction element (26) is moved to engage the side of the rod (18) to lock the rod in abutment with the component so that the rod can subsequently transmit the necessary force to the component to insert the terminal pins into the holes in the substrate. The friction element (26) is actuated by a piston (23) through a bell-crank lever (28), the piston being controlled by the valve means (not shown) which control the actuation of the grippers.

摘要： 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 to close and open the jaws (4 and 5) of the grippers. The device is intended for use in an apparatus which is designed to handle components of different widths, and the device is constructed so that the gripper jaws can be opened wide enough to accommodate the widest component. In order to reduce the space required between the components on the substrate for the opening of the jaws to release a component (6) after it has been placed on the substrate, a stroke-limiting device is provided which is arranged for abutment with one of the grippers after an initial relative movement between the grippers in the direction to open the jaws, so that the initial stroke of the grippers in this direction is limited to a small amount which is sufficient to release the component. The gripping device is then raised above the component and the stroke-limiting device is rendered inoperative so that the jaws can be fully opened. The stroke-limiting device comprises an abutment member (7) in the form of a rod (8) which is slidable in a bore (11) in one of the grippers (1) and has a head (9) with an abutment surface (12) for cooperation with an abutment surface (14) on that gripper, a spring (16) being arranged to urge the abutment member (7) to a position in which the abutment surfaces are spaced from one another (FIG. 1). The rod also extends between two clamping members (18 and 19) in the other gripper (2), which clamping members are operable by fluid pressure to clamp the rod between them to lock the abutment member to this gripper. In the locked operative condition of the abutment member the gripper jaws can be opened only by a small initial amount which is determined by the abutment of the two abutment surfaces. The abutment member is rendered inoperative by releasing the clamping members. The grippers can then be opened fully.
