针对自动化辅料过程中零件尺寸的高精度检测问题，提出了利用双路激光-CCD进行补偿检测的方法，该方法采用光三角测量原理，用两路激光-CCD同时对零件进行检测，减小或消除了自动输料过程中由于零件跳动所带来的测量误差，在所研制的检测系统中，解决了零件的瞬时定位、双路CCD的同步驱动、惯性自适应浮动二值化和高频计数电路等技术关键实验结果表明，该系统对输送中零件的尺寸检测精度达到±0．5μm，具有很好的工程实用性． Aiming at the problem of high-precision parts size detection in the process of automatical excipient, a method of compensating detection by using dual laser-CCD is proposed. The method uses the principle of optical triangulation to detect the parts simultaneously with two laser-CCDs, Eliminating the measurement error caused by part bouncing in the process of automatic material feeding, the instantaneous positioning of parts, synchronous drive of dual CCD, inertial adaptive floating binary and high frequency counting Circuit and other key technical experimental results show that the system of conveying parts in the size of the detection accuracy of ± 0.5μm, with good engineering practicability.
