目的 为了解决GDX6S包装机出口至烟包输送通道、烟包存储装置、C800包装机入口处烟包输送、存储、包装等过程中容易导致烟包外观质量缺陷，而且无任何检测装置对其进行有效检测与剔除的问题。方法 设计一种新型烟包外观视觉检测装置，通过对其关键技术的研究，综合工业相机及触发脉冲信号的安装，全方位可旋转支架的设计制作与安装，动态图像的采集与处理，PLC控制程序的设计等，实现烟包外观缺陷产品的动态检测及准确剔除。结果 该外观视觉检测装置安装后，对烟包外观缺陷产品检测剔除率≥99%，误检率≤0.9%。结论 该烟包外观检测装置能提升产品质量，降低物耗，提高设备作业率，降低有缺陷烟包进入下道工序的风险，可推广应用于行业内所有包装机组设备上。

The work aims to solve the problem that the appearance quality defects of cigarette packet are easily caused in the process of cigarette packet conveying, storage and packaging from the GDX6S packaging machine outlet to the cigarette packet conveying channel, the cigarette packet storage device and the C800 packaging machine inlet, and no detection device can effectively detect and eliminate such defects. A new type of appearance visual detection device for cigarette packets was designed. Through the study on its key technologies, the installation of integrated industrial cameras and trigger pulse signals, the design and installation of an omni-directional rotatable bracket, the collection and processing of dynamic images, and the design of PLC control programs, the dynamic detection and accurate elimination of appearance defect product of the cigarette packet were realized. After the proposed appearance visual detection device was installed, the detection elimination rate of the appearance defect product of the cigarette packet was ≥99.9%, and the false detection rate was ≤0.9%. The proposed cigarette packet appearance detector can improve the product quality, reduce the material consumption, improve the equipment operation rate and reduce the risk of the defective cigarette packet entering the next process. It can be applied to all packaging units in the industry.
