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. The working apparatus is so constructed that the carriers, during restoration movement, do not interfere with other carriers and works moved thereby. The present invention is characterized in that the loading time necessary to move a completed work from the work station and move the next work to the work station can be reduced considerably, thereby improving efficiency.

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.

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.

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.

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.

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.

A transfer rack 15 loaded with a seriate number of component supply cassettes 14 to be handled collectively is carried and retained on a truck 61 so that it can be taken in and out of the truck 61. The transfer rack 15 is passed between the truck 61 and a component supply section 8. Thus, the withdrawal of the transfer rack 15 from the component supply section 8 to the truck 61 and the delivery of the transfer rack 15 to the component supply section 8 are executed in a timely manner so as to change the component supply cassettes 14 at the component supply section 8. The transfer rack 15 delivered to the component supply section 8 is positioned by operating an automatic positioning means at the component supply section 8 in a direction in which it is loaded and unloaded and in a direction perpendicular to the direction in which it is loaded and unloaded.

Disclosed is a component mounting method. Moved in first and second orthogonal directions is a first mounting head section having first nozzles. The first mounting head is rotated such that the first nozzles rotate and successively pickup components from a first component supply table arranged on one side of a board transfer path. These components are then successively mounted onto a board positioned in the board transfer path. Moved in third and fourth orthogonal directions is a second mounting head section having second nozzles. The second mounting head section is rotated such that the second nozzles rotate and successively pickup components from a second component supply table arranged on an opposite side of the board transfer path. These components are then successively mounted onto the board while positioned in the board transfer path.

A transmission mechanism includes a pressing stroke controller for changing the effective pressing stroke of each feed lever of a component feeder unit corresponding to a predetermined pitch of carrying electronic components in respective component feeder unit, whereby the vibration generated when the transmission mechanism is in operation is reduced. Adverse effects on a component feeder unit having small components thereon at a fine pitch which is susceptible to the vibration will be prevented, and the feeding speed can be increased to be more productive.
