摘　　要：针对微小轴承人工目测效率低、漏检率高等问题,结合微小轴承表面缺陷计算机视觉检测系统控制的总体要求,对分拣系统的组成、可编程控制器(PLC)系统选择、I/O点数确定、PLC与上位机通信进行了研究,设计了基于PLC的软、硬件系统,分拣机构可实现微小轴承的自动输送、翻转及剔除等各种运动。多次实验结果均表明,该分拣系统达到了预期的功能要求,稳定性好,可以应用于实际生产中。It has a low efficiency to find the defect on micro bearing surface by using manual method.Aiming at this problem,the inspecting setup,choice of programmable logic controller（PLC） system,I/O point quantity scheme,and the correspondence between PLC and upper computer were studied based on the whole requirement of computer vision detection system for micro bearing defect.Then an automatic inspecting system was developed,in which the sorting equipment controlled by a PLC can realize many actions,including automatic feed,turn and elimination.Several experiments were carried out to validate the effectiveness of the proposed inspecting system.The results show that it realizes the expected functions and has a high stability,and the system can be used for actual production.
