  • Patent number: 6691401
    Abstract: A device for mounting components using mounting heads having a plurality of suction nozzles that provide a plurality of component pickups, positions or mounting operating positions. The mounting heads are positioned on a rotating table that is cooperatively positioned adjacent a component supply table having a plurality of component feeder members. The control unit can rotate the rotating table to position a mounting head at a component supply position and further position one of the plurality of suction nozzles to a first, second and third section operating position for picking up a component from a component feeder. The relative movement of the component supply table and the positioning of first and second suction operating positions relative to our reference point where the edge of the rotating table contacts the line of movement of the component supply table can increase the pickup speed of components.

  • Publication number: 20010003865
    Abstract: A method for mounting components using mounting heads for which a plurality of suction or mounting operating positions are set for suction nozzles in a state where the mounting head is at rest in a component supply position or component mounting position, it being possible to select any of these operating positions, comprising a first step of selecting a component supply position or component mounting position such that the amount of movement of component feeder holding components to be mounted, or the amount of movement of the substrate to the mounting position for the next component to be mounted becomes a minimum, and moving the component feeder or substrate accordingly; and a second step of selecting a suction nozzle position corresponding to the component suction position or component mounting position in the first step, whilst the mounting head is moving towards the component suction position.

  • Patent number: 5692293
    Abstract: There is disclosed an automatic electronic part-mounting apparatus in which acceleration, acting on electronic parts, suction-held respectively by mounting heads, is reduced, thereby enabling stable mounting of the electronic parts. Cam levers 10 are pivotally mounted through respective pivot shafts 9 on a rotary member 8 which is rotated at a constant speed by a roller gear cam 19. One end of the cam lever is engaged with a fixed cam 7 whereas the other end thereof is slidably mounted through cam followers on a follower lever 12 slidably mounted on annular rails 11 in a housing 6. One end of the follower lever 12 is slidably engaged with a cam follower, and the other end of the follower lever 12 is mounted on each mounting head 13. With this construction, the acceleration of the mounting head 13 can be reduced.

  • Patent number: 5525023
    Abstract: A chip component supply apparatus of the invention includes a container box for storing chip components in pieces, a means for conveying chip components from the container box onto a conveyor belt, which moves intermittently and conveys the transferred chip components toward a take-out port area where a vacuum suction nozzle of an electronic component placement machine takes out the chip components. A stopper is positioned in the vicinity of the take-out port area for stopping the chip components conveyed by the conveyor belt at the take-out port area. The stopper moves and departs from the vicinity of the take-out port area when the conveyor belt finishes intermittent motion and stops, and returns and is positioned at the take-out port area before the next chip component conveyed by next intermittent motion of the conveyor belt reaches the take-out port area.
