HIGH RESOLUTION PARTS HANDLING SYSTEM |
摘要 |
A high resolution article handling system serves as an article discriminator or identifier by creating an object silhouette. The objects are singulated on a conveyor and scanned by a linear array of CCD units (2048 pixels per inch) at a scan rate of 10 MHz. Pixel transitions corresponding to object edge points are converted to a single count value from a counter which is synchronized with the scanner. A microprocessor with a first in, first out buffer memory needs only a capacity to handle the count value rather than all data from the pixels. Article orientation is corrected in response to signal generated by determining the count value difference between a reference value and a work article value at only the scan slice windows at equally spaced positions along the article length where differences have been predetermined to be a maximum. |
