COMPONENT-RECOGNIZING APPARATUS, SURFACE-MOUNTING APPARATUS, AND COMPONENT-INSPECTING APPARATUS

摘要

In an apparatus adapted to scan a lower side of an electronic component being suction-held by a suction-holding nozzle, to perform image recognition of suction-held conditions of the electronic component, this invention is intended to perform a transfer operation under a condition that the suction-holding nozzle is arranged closer to an upper surface of a base, wherein the optical path directed downwardly from the suction-holding nozzle is bended in a lateral direction by a first optical path changing member and then further bended in another direction by a second optical path changing member to allow image-sensing means to capture an image of a lower surface of the suction-holding nozzle, and the electronic component being suction-held by the suction-holding nozzle is illuminated along the lateral optical path changed by the first optical path changing member.

主权项

1. A component-recognizing apparatus comprising a scanning unit which is installed to a movable head unit having a suction-holding nozzle capable of suction-holding an electronic component, the scanning unit being adapted to be displaceable in a direction relative to the suction-holding nozzle, the scanning unit being operable to capture an image for image recognition of suction-held conditions of the electronic component being suction-held by the suction-holding nozzle,
said scanning unit including: a first optical path changing member which is adapted to be located beneath the suction-holding nozzle and is operable to bend the optical path directed downwardly from the suction-holding nozzle in a lateral direction during the image-sensing operation; a second optical path changing member operable to further reflect the reflected optical path in another direction so that the reflected optical path directs upwardly at a given elevation angle relative to a horizontal plane; and image-sensing means disposed in the optical path changed by the second optical path changing member, the image-sensing means is operable to capture an image of a lower surface of the electronic component being suction-held by the suction-holding nozzle through the first and second optical path changing members.
