A parts feeder for feeding parts that are disposed on a carrier having a base tape and an adhesive tape. Parts are disposed above holes which are formed at equal intervals on the base tape, and the parts are held by an adhesive tape adhered to a lower surface of the base tape. The feeder includes a pitched feeding mechanism for intermittently feeding the carrier tape at a predetermined pitch, a separating mechanism for separating the adhesive tape from the base tape in synchronization with the feeding of the carrier tape at an adhesive tape separating stage, and a pressing mechanism for pressing the parts disposed on the base tape against the base tape prior to the separation of the adhesive tape from the base tape at the adhesive tape separating stage.

Parts feeder

A method and an apparatus for carrying a workpiece for improving efficiency in a workpiece carrying operation. In the apparatus, a moving member having a workpiece holding member is driven with a linear motion in a horizontal plane along a carrier passage, and the workpiece holding member is driven with a revolutional motion in a vertical plane around a revolution axis displaced from a center of the workpiece holding member, while the workpiece holding member maintains an orientation in which a holder holding the workpiece points downwards. The holder of the workplece holding member is controlled to sequentially carry out holding of the workpiece and releasing of the workpiece at lowest positions of the workpiece holding member in the revolutional motion, so as to realize a continuous workpiece carrying operation.

Method and apparatus for carrying workpiece by continuous workpiece

A work mounting apparatus according to the present invention comprises a rotating drum divided into upper and lower drums, a head unit arranged on the outer periphery of the rotating drum or the lower drum, a circular work head attached to the head unit, and a suction nozzle protruding from the outer peripheral surface of the work head toward a workbench. While the lower drum is rotating, the suction nozzle of the work head repeats cycloid motion along the workbench with its posture or orientation kept fixed with respect to the workbench. While repeating the cycloid motion, the nozzle receives a work from a work feeder of the workbench by suction, and mounts the work on a printed board on the workbench. The work mounting apparatus further includes a balance weight for the work head, and a friction brake for applying a frictional force to the turning shaft of the work head, to thereby stabilize the turning motion of the work head.

Cycloid motion work mounting apparatus

In a parts mounting apparatus, suction nozzles are mounted on a rotating carrier driven by a motor. With rotation of the rotating carrier, parts are sucked by the nozzles at a feed station and carried to a mounting station where the parts such as electronic parts are mounted on substrates, for example. A counter counts output pulses from an encoder mounted in the motor driving the rotating carrier. A microcomputer determines the rotational speed and rotational position of the rotating carrier from the count value of the counter. Based on the result of the determination, the microcomputer calculates a timing for delivering a signal for switching the nozzles between two different pneumatic states.

Parts mounting apparatus

A work mounting apparatus or component mounting apparatus according to the present invention comprises a lower drum of a rotating drum, a head unit arranged on the outer periphery of the lower drum, a circular work head or component head attached to the head unit, and a suction nozzle protruding from the outer peripheral surface of the work head toward a workbench. While the lower drum is rotating, the suction nozzle of the work head repeats cycloid motion along the workbench with its posture kept fixed with respect to the workbench. While repeating the cycloid motion, the nozzle receives a work or component, such as an electronic component from a work feeder of the workbench by suction, and mounts the work on a printed board on the workbench. The work head is rotated for a predetermined rotational angle during the process in which the suction nozzle moves from the work feeder toward the printed board after the work is received, or in the process in which the nozzle moves from the printed board toward the work feeder after the work is mounted. Thus, the region for the cycloid motion of the suction nozzle is upwardly separated from the workbench.

Electronic component mounting apparatus

A work or component mounting apparatus according to the present invention comprises a rotating drum arranged above a workbench and divided into upper and lower drums, a head unit detachably mounted to the lower drum of the rotating drum, a circular work head (or, in other words, a component head) attached to the head unit, a suction nozzle protruding from the outer peripheral surface of the work head toward the workbench, and a controller housed in the upper drum of the rotating drum for controlling the turning motion of the work head and the supply of suction pressure to the suction nozzle. While the lower drum is rotating, the suction nozzle of the work head repeats cycloid motion along the workbench with its posture kept fixed with respect to the workbench. While repeating the cycloid motion, the nozzle receives a work from a work feeder of the workbench by suction, and mounts the work on a printed board on the workbench.
