目的 解决YP13装封箱机生产过程中产生的箱装烟条缺条缺陷产品不能有效被检测及剔除的问题。方法 设计一种新型YP13装封箱机缺条视觉检测系统，通过对其关键技术的研究，综合集成工业相机及触发脉冲信号的安装、支架设计的安装、动态图像的采集、PLC控制程序的设计等，实现箱装烟条缺条缺陷产品的高效检测及准确剔除。结果 该视觉检测系统实施后，箱装烟条缺条缺陷产品检测剔除率≥99.9%,误检率≤0.02%。结论 该视觉检测系统能提升产品质量、降低物耗，可推广应用于行业内包装规格为每件2×25条或25条的装封箱设备上。

The work aims to solve the problem that the defective carton-missing products packaged in cases cannot be effectively detected and eliminated in the production process of YP13 case filling and sealing machine. A new visual inspection system of YP13 case filling and sealing machine was designed. By studying the key technology and integrated with the installation of industrial camera and trigger pulse signals, designing the mounting bracket, capturing the dynamic image and designing the PLC control program, etc., the efficient detection and accurate elimination of defective carton-missing products packaged in cases were achieved. After the visual inspection system was put into use, the detection and rejection rate of such defective products was greater than or equal to 99.9%, and the false detection rate was less than or equal to 0.02%. As the visual inspection system can improve product quality and reduce material consumption, it can be popularized in all the case filling and sealing machines of 2×25 bars or 25 bars in the industry.
