Abstract: An electronic parts mounting apparatus, has a part mounting head on which nozzles for holding different sized electronic parts can be exchangeably mounted; the suction nozzles each having a reflection member thereon for receiving light from below a suction end of the nozzle and reflecting it past the suction end of the nozzle; a recognizing device below the part mounting head for receiving light from the direction of the part mounting head; a first illuminating device adjacent the recognizing device for directing illuminating light to a reflection member on a nozzle on the part mounting head for causing the reflecting member to reflect the illuminating light past a part held on the suction nozzle to direct a transmitted light image of the part to the recognizing device; a shutter movable toward and away from the part mounting head adjacent a position of a nozzle thereon for, when the shutter moves toward a nozzle, engaging the nozzle and blocking light from the first illuminating device from reaching a reflec

Abstract: An electronic component mounting apparatus has a movable table on which plural component supply units are arranged in parallel. Each of the component supply units accommodate an electronic component to be mounted on a component mounting member. A guide frame supports the table to move in a direction intersecting perpendicularly to a component supply direction of the component supply unit. A driving shaft is arranged in the direction intersecting perpendicularly to the component supply direction of the component supply unit for moving the table. A positioning device positions the component mounting member. A component mounting device holds the components and mounts the components on the mounting member, and a support member supports the driving shaft at a middle thereof.

Abstract: The present invention relates to improvement in a working apparatus, such as an electronic part automatic-mounting apparatus comprising carriers for holding and moving works on a working line and a work head for applying a predetermined operation at a predetermined position on the work moved by the carriers, to a work station. The apparatus also includes: head driving means for moving the work head in directions (for examples, a Y direction) different from the moving direction of the work (for example, an X direction) and carrier driving means for moving the carriers along the working line sequentially from a work feed position to a work station, onto a work discharge position and then moving or restoring the work back to the work feed position (7). The carrier driving means also position the point of operation on the work in the moving direction fo the work at the work station.

Abstract: A part such as electronic parts is irradiated by diffused light and a silhouette of the parts is sensed by an image sensor, and plural optical systems are placed between the parts and the image sensor, and thereby the silhouette of the parts is divided into plural portions, moreover a shutter having plural openings is provided between the image sensor and the optical system to select one of the plural optical systems; thus one of respective silhouettes of the plural portions is sensed by the image sensor, and the portions are sensed in turn by shifting the shutter.

Abstract: An electronic component mounting device for mounting an electronic component onto a circuit-board, is provided with an intermittently rotatable rotary frame, a plurality of elevating members disposed around and along the periphery of the rotary frame at regular intervals so as to be free to move up and down, a plurality of electronic component holding members respectively securely mounted on the elevating members each to hold one electronic component at a time, an index unit for controlling the intermittent rotation of the rotary frame by way of a shaft, a cam mechanism for moving the elevating members up and down with the rotation of the rotary frame, and an operating member for moving any one of the electronic component holding members up and down.

Abstract: In the mounting of an electronic component, a holding member is rotated by a predetermined angle prior to actual holding of the electronic parts, thereby to detect a center of the holding member from at least two positions of the rotation angle, and the rotation center of the holding member is found by a calculation based on the detected center of the holding member. The position of the electronic parts against a circuit board then is corrected on the basis of a deviation between the position of the rotation center and the center of the holding member.

Abstract: A method of optical recognition of a component suction-gripped by a suction nozzle, wherein, when a small component (P) is illuminated by a first illuminator (23), from cone-shaped reflector provided on the base part of a sucking nozzle (3), thereby making a silhouette image of the small component, and when a large component (P') is suction-gripped, a second illuminator, having two-piece movable translucent sheets (25a+25b, which are opened to pass the large component (P') through a thus-opened gap, illuminates the large component (P') to make its silhouette image. By using a lightweight nozzle, a silhouette of the large component is obtainable, assuring high speed mounting of components.

Abstract: An electronic component transporting apparatus employing taping cassettes includes a toothed wheel arranged for meshing engagement within successive compartments of a taping cassette after a sealing tape has been stripped from the taping cassette and components contained in compartments thereof have been successively removed, whereby stepwise rotation of the toothed wheel is utilized to produce stepwise advancement of the taping cassette for successive removal of electronic components contained in the compartments. Since it is not necessary to provide a line of perforations along an elongated side of each taping cassette, for use in driving the cassette, each cassette can be made substantially smaller in width than has been possible in the prior art.

Abstract: A moving table type work system includes a work table (3) arranged to provide the movements of two degrees of freedom for a work piece (a) to carry out a predetermined work for the work piece (a). Further included are a feeding table (1) which is reciprocated between the work table (3) and a work piece feeding device (2) to transfer the work piece (a) from the work piece feeding device (2) to the work table (3) and a discharging table (4) which is also reciprocated between the work table (3) and a work piece receiving device (5) to transfer the work piece (a) from the work table (3) to the work piece receiving device (5).

Abstract: An apparatus for mounting electronic components on a printed board substrate comprisesa component feeder for sequentially feeding the electronic components in an aligned row,a chuck which receives and rectifies by pinching the position of the electronic components,a vertically movable mounting head, which holds by air suction one of the electronic components preliminarily pinched and rectified of the position by the chuck, and goes down through a wide open gap of the chuck to mount the electronic component on an accurate position of the substrate.
