链板自动分选整列机采用６３２８Ｈｅ－Ｎｅ激光器和ＣＣＤ作为光发射接收系统提取流水线上的链板的形态信号，通过对漫反射光的宽度及最大偏移进行了深入的研究计算，从而使本装置的误选率≤０．８％，达到了在线实时检测与分选整列链板的需求
The automatic sorter of the chain board uses the 6328 He-Ne laser and the CCD as the optical transmitting and receiving system to extract the shape signal of the chain plate on the pipeline. By deeply studying and calculating the width and the maximum deviation of the diffuse reflected light, So that the error rate of this device ≤ 0.8%, to achieve the online real-time detection and sorting of the entire column chain needs
