摘　　要：为实现对磁性零件的在线计数检测 ,开发了一种在线式磁性零件激光光电计数仪系统。采用激光光源 ,缩束光管 ,光束发散小 ,准直性好 ;采用对辊式自动排料机构和圆刷式梳料器 ,工件排列有序 ,下料速度快 ,解决了目前磁性零件大批量计数的问题。该计数仪具有计数准确、快速和适应多种规格产品计数的特点 ,对 3～ 10 0 m m和厚度 1～ 2 0 m m的零件均可进行计数 ,并且计数速度可达到 10 0 0件 /分以上 ,已应用于实际生产中。To accomplish on-line count inspection for magnetic parts, a kind of laser photoelectric counter system is developed based on photoelectric inspection theory. Laser light source is adopted. Through bunching, light diverges little and has good collimation. Double-roll auto-discharging mechanism and round-brush divider are adopted. Parts are arranged orderly and rapidly, so plentiful magnetic parts can be counted. This system has special features such as high accuracy, fast response and good adaptability. It can be used to count parts with diameters from 3mm to 100mm and thickness ranges from 1mm to 20mm. Its rapidity can reach 1000 parts per minute. This system has been employed in practical manufacture.
