Abstract: A tape and reel inspection system is provided with OCR testing of devices, network retrieval of device lot information, and automatic teaching of image patterns. Each device lot is typically accompanied by a travel sheet, which includes a history for the device lot. The travel sheet may include a bar code to allow the system to receive the device lot number while reducing the possibility of human error. The system performs OCR on a first device. The system communicates with a database to obtain lot information. The system combines lot information and package information to form marking information. The system then compares the contents of the markings with line information obtained from the marking information. Once a first device passes the OCR test, the system trains an image of the first device. Image training may be done automatically without intervention from the operator. If a subsequent device fails the image test, the inspection system automatically performs OCR on the failed device.

Abstract: A vision inspection system is provided in which eight optical images are instantaneously recorded on singular image frames which are output from two optical cameras. An illumination source is provided for illuminating four spaced apart inspection regions which are disposed about an inspection window. Two optical signals of reflected light emanate from each of the four inspection regions and are directed toward two optical cameras, with the two optical signals from each of the optical regions being at different viewing angles and preferably from a single focal point. Optical directing members receive the optical signals from the various regions and direct the light to respective ones of the cameras. The optical directing members are selectively adjustable for accommodating components of various sizes. The optical inspection of each component instantaneously occurs by recording the eight optical images, on two frames, one frame being recorded by each of the cameras.

Abstract: A method and apparatus for inspecting the sidewalls of containers on a continuously-moving conveyor includes recording instantaneous upper and lower angularly-spaced images of the bottles as they pass. Data on the images is stored as numeric data indicating the grey shade of each pixel in a matrix of pixels, which matrix is examined for edges and then divided based on detected edges into inspection windows. The windows are subject to separate criteria between typically scuffed areas and open areas. The occurrence of pixels in at least three grey ranges reflecting clear glass, opaque glass, and scuffed glass, together with the correlation of such occurrences between angularly-spaced views and upper and lower views, is processed to detect defects. A memory stores a status indication in a queue representing the acceptability of the bottles being examined, which are then segregated by a downstream reject kicker mechanism.
