Abstract: The invention is an automated solder joint inspection system for determining the quality of a specular soldered joint through examination of the shape of the joint surface using a series of point light sources and the associated highlight reflections from the joint surface. The light from point light sources, which is directed toward the solder joint, is reflected in a pattern from the solder joint to an array of light responsive transducers from at least one location. Utilizing the intensity values from the light responsive transducer array, the surface orientation of the solder joint at a number of points is determined. The solder joint is evaluated in one of two ways. In one way, using known surface features of solder joints along with curve fitting techniques, a series of grid maps is mathematically interpreted to reconstruct the solder joint surface. A rule-based system, through comparison with acceptable solder joint surface features, evaluates and classifies the joint for an acceptability determination. In another way the surface orientation is used to generate an Extended Gaussian Image of the joint and the features of this are analyzed.

Abstract: An inspecting apparatus includes an illuminator, a light sensor positioned on one side of the path of movement of containers opposite to the illuminator capable of receiving rays of light which have passed through the container, rays of light reflected fro the container and rays of light travelling straight from the illuminator towards the light sensor within a predetermined region exteriorly of the container, a detector for analyzing the rays of light received by the light sensor, and a light absorbing or shielding member positioned diagonally and to the side of the container as viewed in a direction from the light sensor towards the illuminator. The light absorbing or shielding member shields rays of light reflecting from the surfaces of each of opposite wall portions of the container. Thus, a line of shade corresponding to the contour of the container can be formed on the side of the light sensor for accentuating the boundary between the container, illuminated by the rays of light from the illuminator, and a predetermined region defined exteriorly of the ocntainer by the rays of light travelling striaght towards the light sensor.

Abstract: A method and apparatus for inspecting a transparent container having a defect on the container bottom by monitoring and analyzing the light energy transmitted through the container bottom. A source of diffused illumination is provided to direct the diffused illumination through the container bottom for monitoring the light energy by camera. The diffused illumination is arranged to be directed in intensity greater through a peripheral region than through a central region of the container bottom so as to positively produce a pair of peak values in light energy distribution received by the camera along at least one dimension corresponding to a line or secant extending in a plane of the container bottom. A corresponding pair of positions having such peak values and spaced along the dimension is obtained as indicative of the opposed peripheral edges of the container bottom, which positions are then processed to provide a true center of the monitored image as corresponding to the center of the container bottom. Based upon thus determined center of the image, it is defined an inspection zone which is in exact coincidence with the actual container bottom and within the confines of which the monitored light energy is analyzed to detect a defect on the container bottom. Thus, the defect inspection can be made free from an erroneous background outside of the container bottom to give a reliable detection of a defect on the container bottom.

Abstract: Apparatus for inspecting sheet material having known characteristics is disclosed. The apparatus comprises means for providing a plurality of pixel signals each having a magnitude representing the intensity of electromagnetic radiation received from a corresponding point on the sheet material. The apparatus also comprises signal processing means for comparing the magnitude of each one of the pixel signals to a corresponding reference range defined by the known characteristics of the sheet material and generating a characteristic signal. The characteristic signal includes an event signal for each of the magnitudes falling outside of the corresponding reference range and a data signal for each of the magnitudes falling within the range, wherein the data signal represents the magnitude of the pixel signal. The signal processing means also generates an address signal representing the point on the sheet material at which the characteristic signal is generated. The apparatus also comprises system processing means for storing the event signals and the corresponding address signals to provide an indication of deviation from the known characteristics of the sheet material.

Abstract: An article inspection system especially useful for containers having threaded ends includes a video camera, digitizer and data processor operable to analyze a video image collected through a lens system. The lens system has several alternatives, in each case including a wide aspect object lens, wider than the end of the article being inspected, with a refracting and/or reflecting light ray path operable to produce a two dimensional image including both the end of the article and the sides of the article adjacent the end. The optics produce a distorted image in which the sides of the article appear folded upwardly into the two dimensional image such that a two dimensional data array adequately represents the image of the end and the adjacent sides.
