光电式产品外观质量检验机是利用光照射在产品表面上,利用其对好面与缺陷反射(或透射)的差异(反射率的大小,反射方向的变化)直接或通过一定的光学系统,用光敏元件将其变化转换成电信号后,对产品进行分类的机器。这类分选设备中的主要部件—光电传感器,具有识别表面特征的能力,可以代替一些靠人的感觉进行的检查工作。光电传感器无论是使用在反射或透射情况,其原理均可用反射接收的情况来说明。重庆大学已研制成功用于产品外观检验机
Optical appearance of the product quality inspection machine is the use of light on the surface of the product, the use of its good surface and defect reflection (or transmission) of the difference (the size of the reflectivity, the direction of reflection changes) directly or through a certain optical system, Photosensitive components will be converted into electrical signals, the product of the classification of the machine. The main component of this sorting device, the photoelectric sensor, has the ability to identify surface features and can replace some human-based inspections. Whether the photoelectric sensor is used in the case of reflection or transmission, the principle can be described by reflection reception. Chongqing University has successfully developed for product appearance inspection machine
