Working apparatus

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.

Parts recognition method and apparatus therefor

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. The index unit can interrupt the rotation of the rotary frame to bring each electronic component holding member to a stop at least at one location suitable for supplying each electronic component and at another location suitable for mounting each electronic component onto the circuit-board. The operating member is driven by a linear motor so that each electronic component is firmly mounted onto the circuit-board.

Electronic component mounting device

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.

Method and apparatus for mounting electronic parts

The present invention is a part mounting device for mounting chip parts on a substrate, comprising a linear motor having a columnar yoke with upper and lower ends thereof pivotably supported on the device, permanent magnets disposed in the vicinity of the columnar yoke and forming with the columnar yoke a magnetic circuit, and a bobbin disposed in the vicinity of the columnar yoke and slidable in the columnar direction of the yoke;

Method of loading parts

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.

Illuminating device and method for a component detecting apparatus

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.

Electronic component transporting apparatus employing taping cassettes

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). The feeding table (1) is controlled to be in unitary movement relation to the work table (3) while the feeding table (1) is connected to the work table (3) so that the work piece (a) is transferred to the work table (3) therefrom and the discharging table (4) is also controlled to come into unitary movement with the work table (3) while it is connected to the work table (3) so that the work piece (a) is shifted from the work table (3) thereto.
