  • Patent number: 6618135
    Abstract: A laser beams inspection apparatus suitable for inspecting electronic components such as ICs mounted on a substrate. The inspection apparatus includes a scan mechanism. The scan mechanism works to move a laser beam emitted from a laser emitter to scan a target one of electronic components in a given scan range. The scan mechanism is designed to change orientation of emission of the laser beam to change the scan range as a function of the type (e.g., the size) of the target electronic component, thereby minimizing inspection errors regardless of the type of the electronic components to be inspected.

  • Patent number: 5787191
    Abstract: A wiring pattern inspection apparatus for inspecting an abnormality of a wiring pattern formed on a printed circuit board, which is equipped with an optical image pickup device for optically illuminating a surface of the printed circuit board including the wiring pattern to photoelectrically convert optical information of the printed circuit board surface due to the optical illumination into a grey level image. This grey level image is converted into a bi-level image which separates the grey level image into the wiring pattern side and a background side of the wiring pattern. Thereafter, the bi-level image is once contracted by a first size and then expanded by a second size so as to eliminate a micro conductive portion left on the printed circuit board or a micro pinhole which can be disregarded in the abnormality inspection, thereby preventing the excessive detection.

  • Patent number: 4460108
    Abstract: Apparatus for feeding electric circuit elements includes a plurality of containers or stockers for electric circuit elements, a transfer member connected to a respective stocker for transferring the circuit elements, and a shutter assembly disposed across the feeding path of the transfer member, whereby a plurality of circuit elements are fed at one time by one stroke of the shutter assembly. The shutter assembly may have a cut-out portion at the edge thereof and is adjustably removable in a direction perpendicular to that of the stroke thereof to open the feeding paths which correspond to the cut-out portion. The stocker may include a receptacle, the bottom of which defines an opening to receive a capture member. The capture member has plural through holes extending axially therethrough and is opened at its conical top thereof to receive circuit elements by reciprocal movement of the capture member relative to the receptacle.

  • Patent number: 4457451
    Abstract: An apparatus for feeding electric circuit elements has a hopper for accommodating a supply of such elements, a capture tube or pipe extending substantially vertically through a bore in the bottom of the hopper which is movable relative to the tube in the direction of the axis of the latter so that the electric circuit elements in the hopper are captured one at a time by the tube and fed therethrough to a predetermined position at the outside of the hopper, and a separating plate disposed above the opening of the tube in the hopper for shielding the electric circuit elements under the separating plate from at least part of the weight of the electric circuit elements thereabove whereby the hopper can be provided with a large vertical dimension for accommodating a correspondingly large supply of the electric circuit elements without the danger that elements near the bottom of the hopper will be damaged by reason of the relative movement of the capture tube under the weight of the superposed circuit elements.

  • Patent number: 4336872
    Abstract: Leadless electronic parts or the like are transferred from hoppers under the influence of gravity or by forced air through tubes of polygonal cross-section to a prepositioning template. The polygonal cross sections of the transferring tubes tend to damp out oscillatory motion of the parts and to speed their travel through the tubes. Each polygonal, preferably triangular, tube is preferably obtained by deforming a tube of circular cross-section in a forming machine including a plurality of discs arranged so that their peripheries define a polygonal space therebetween through which the tube of circular cross section is driven.
