Abstract: In an electronic component mounting apparatus, nozzle mechanisms are formed slender by providing shaft-type linear motors vertically upward of nozzle units and providing linear encoders vertically upward of the shaft-type linear motors, respectively. Thus, it becomes possible to reduce the occupational area of the individual nozzle mechanisms in XY directions (horizontal direction), thereby allowing the pitch of neighboring nozzles to be narrowed. It also becomes achievable to keep up with increasingly narrow mounting pitches of electronic components on boards of increasingly smaller-size and higher-integration.

Abstract: An electric parts mounting apparatus includes rotary type multi-nozzle mounting heads. Each of the mounting heads has a plurality of suction nozzles disposed in a radial manner on a rotor mechanism, which rotates around a rotation shaft. A parts mount mechanism is configured such that the axial direction of the rotation shaft coincides with an arrangement direction of tape feeders. A shaft-to-shaft distance of the suction nozzles is set to be plural times as large as a pitch of the feeder arrangement. In a pick up process, a plurality of electronic parts can be simultaneously picked up from the tape feeders. In a parts mounting process, while one of the mounting heads mounts the part, the other mounting head can complete a nozzle changeover operation such that the suction nozzle holding an electronic part to be mounted next is moved to an operation position.

Abstract: A parts supply apparatus for moving individual electric parts from a bulk supply of electric parts to an outlet where a part mounting apparatus picks each part up. A parts guide path is located below the bulk supply so that the parts are moved therethrough by force of their own weight. The center of gravity of the parts supply apparatus is preferably located relatively far away from the outlet, so that vibration of the bulk supply of parts to move them into the parts guide path does not cause significant vibration of the outlet and interference with a secure mounting of the parts onto a part mounting apparatus.

Abstract: In a bulk feeder, chips, stored randomly in a storage chamber, are fed one by one into a pipe extending vertically downwardly from the bottom of the storage chamber, and are further sequentially fed to a pickup position. In order to prevent the incomplete feeding of the chips into the pipe, an outer tube is provided in a manner to insert the pipe into the outer tube, and two projections are formed around an outer peripheral surface of the outer tube, and a pin is received between the two projections. The pin is rotated by a motor in eccentric relation to a horizontal axis of rotation of this motor, and the outer tube, while rotating, moves upward and downward, so that an upper end portion of the outer tube projects upwardly beyond an upper end of the pipe. As a result, the outer tube breaks into and disperses the group of chips residing above the pipe, so that the chips can be fed one by one into the pipe, and then the chips are fed sequentially to the pickup position.
