Abstract: An apparatus for mounting different sorts of electronic components on a substrate, including a table rotatable about an axis; a plurality of groups of mounting heads supported by the table, each one of the head groups consisting of a plurality of identical mounting heads that differ from the identical mounting heads of each of the other head group or groups, the mounting heads of the each one head group taking an electronic component of a corresponding one of the different sorts from an electronic component supply device and mount the electronic component on a substrate.

Abstract: A component supply device for supplying a component mounting device with electronic components at a supply position, which includes at least three supply tables each having a plurality of supply units mounted thereon such that the supply units have respective supply portions which are spaced from each other along a predetermined line, the supply units holding respective groups of electronic components of respective different kinds, a guiding device for guiding the supply tables such that the supply tables are movable in a moving direction parallel to the predetermined line, and a table positioning device for positioning the supply tables in the moving direction so that the supply portions of the supply units are selectively brought to the supply position.

Abstract: A detecting device for detecting a position of an electronic component in which the component is held by a holder is disclosed. The detecting device includes a first light emitter for emitting a first radiation toward a vicinity of the electronic component, a second light emitter disposed in the vicinity of the holder, for absorbing the first radiation, and emitting a second radiation having a wavelength different from that of the first radiation, toward the electronic component, and a photoelectric device disposed on one of opposite sides of the electronic component which is remote from the second light emitter. The photoelectric means is insensitive to the first radiation and receives a projection image of the electronic component formed by the second radiation.

Abstract: Are disclosed a method of detecting a hold-position of an electronic component in which the component is held by an electronic-component holding apparatus, an electronic-component holding apparatus having a hold-position detecting device, and an electronic-component mounting apparatus for mounting an electronic component on a printed-circuit board. The above method includes the steps of emitting light beams in a direction toward the electronic component (W) held by the electronic-component holding apparatus (58, 70), so as to take a projection of the component, and of detecting a position of the projection, thereby detecting the hold-position of the component.

Abstract: A method of taking an electronic component or chip out of each of plural pockets which are formed at regular intervals along a longitudinal direction of a carrier tape and which have openings in the upper surface of the tape, through vacuum suction of a suction member, while the tape is intermittently fed in a feeding direction parallel to its longitudinal direction, including the steps of: (a) bringing the pockets having the chips, into a position where their openings are covered with a covering device having a notch with a width narrower than that of the chip and wider than that of the suction member; (b) feeding the tape by the regular interval in the feeding direction, and permitting a leading chip of the chips covered with the covering device to be brought into a suction position where the leading chip is right below the suction member and the notch; (c) lowering the suction member through the notch so as to allow the suction member to suck and hold the leading chip; (d) retracting the covering device wh

Abstract: An apparatus for conveying and positioning a substrate of a printed-wiring board, comprising: a conveyor system for transferring the substrate, including a pair of parallel spaced-apart side frames at least one of which is movable relative to the other; a positioning device including a support member, a pair of parallel spaced-apart holder members disposed on the support member and movable relative to each other so as to be engageable with opposite sides of the substrate parallel to the side frames, to thereby hold the substrate, and a device for moving the support member along X and Y axes, so as to position the substrate within a predetermined area; a device for moving the support member between an aligned position in which the holder members are aligned with the side frames, and an unaligned position for positioning the substrate in the predetermined area; and a device for connecting the movable holder member and the movable side frame when the support member is in the aligned position.

Abstract: An apparatus for positioning printed-wiring substrates of different sizes comprising: an X-Y table having a movable device movable along X and Y axes; a pair of Y-axis positioning members which are disposed on the movable device and relatively movably spaced from each other along the Y axis, so as to be engageable with opposite parallel sides of the substrate parallel to the X axis, for positioning the substrate along the Y axis; an X-axis positioning member provided on the movable device and engageable with the substrate to position the substrate along the X axis; a first engagement member provided on at least one of the the Y-axis positioning members; a second engagement member which is fixed in position in the Y-axis direction; and a driving device for moving the first and second engagement members toward each other along an axis perpendicular to the Y axis, and effecting engagement of the first and second engagement members with each other, to thereby hold the above-indicated at least one Y-axis positioni

Abstract: Method and apparatus for holding an electronic component prior to its placement on a circuit substrate. The component sucked by a sucker is first centered in one direction by closing movements of a first pair of opposed positioning members toward the component, and then centered in another direction normal to the above one direction by closing movements of a second pair of opposed positioning members which occur only after the first pair of positioning members are opened. The first pair of positioning members are provided on an assembly holding the sucker, and the second pair of positioning members are provided on the sucker holder assembly or separately from the sucker holder assembly. In the latter instance, the assembly holding the sucker and the first pair of positioning members are adapted to be movable relative to the separately provided second pair for alignment of the sucker with the separate second pair.
