Chip-type electronic part storage casing and supply cassette using same

The exterior view inspecting apparatus for circuit board of the invention including a sensor unit for emitting a laser beam to an object to be inspected, and detecting the displacement of the object by focusing the reflected light on a photoelectric transducer by using a receiving lens; an optical path converter unit for refracting the optical path of the laser beam; a sensor head unit incorporating the sensor unit and optical path converter unit; a control unit for moving the sensor head unit along a specified scanning route; a correction unit for correcting the displacement data of the object to be inspected as detected by the sensor unit, and a judging unit for judging the existence and position of an electronic component on a circuit board from the corrected displacement data. The optical path converter unit includes a flat sheet glass inclined relative to the optical path of the laser beam, rotating about the axial center parallel to the optical path. By this optical path converter unit, the optical path of the laser beam is refracted so that the laser beam scans the circuit board drawing a small circular trace. As the trace draws a small circle, the trace detects the end portion of the electronic component on the circuit board multiple times. Consequently, the existence and position of the electronic component on the circuit board can be detected accurately.

Exterior view inspecting apparatus for circuit board

A chip component supply apparatus of the invention includes a container box for storing chip components in pieces, a means for conveying chip components from the container box onto a conveyor belt, which moves intermittently and conveys the transferred chip components toward a take-out port area where a vacuum suction nozzle of an electronic component placement machine takes out the chip components. A stopper is positioned in the vicinity of the take-out port area for stopping the chip components conveyed by the conveyor belt at the take-out port area. The stopper moves and departs from the vicinity of the take-out port area when the conveyor belt finishes intermittent motion and stops, and returns and is positioned at the take-out port area before the next chip component conveyed by next intermittent motion of the conveyor belt reaches the take-out port area. The vacuum suction nozzle of the electronic component placement machine takes out the chip component at the take-out port area when the conveyor belt is stopped and the stopper is apart from the take-out port area.

Chip component supply apparatus

Chip-type electronic elements are applied in line on the surface of a carrier tape before they are supplied to an automatic electronic-element supply apparatus so as to be automatically mounted on a printed circuit board. Side plates are disposed at an end portion of the body frame of the automatic electronic element supply apparatus for a chip-type electronic element mounting apparatus in such a manner that a plurality of carrier tape reels can be fastened to the side plates and the carrier tapes are discharged from the tape reels in a ratchet manner while moving adjacently in parallel to one another through another end portion of the body frame. Thus, a multiplicity of different kinds of electronic elements can be supplied from one supply apparatus.

Chip-type electronic element supplying apparatus

An automatic apparatus for mounting electronic parts on a printed circuit board includes a turntable, a plurality of mounting heads mounted in positions spaced at equal distances around the turntable, a plurality of mounting chucks movably mounted on each of the mounting heads and each having a shape for picking up a different shape electronic part, cams disposed around the periphery of the turntable and engageable with the mounting heads for positioning one mounting chuck on each of the mounting heads in a position for picking up a desired part, carrying the part around the periphery of the turntable and mounting it on the printed circuit board, and a device to drive the mounting chucks to pick up an electronic part and to mount electronic part picked up on the printed circuit board.
