基于机器视觉的笔记本电脑壳体间隙调整系统设计

Research on Gap Adjustment of Notebook Computer Shell Based on Machine Vision

针对在笔记本电脑生产过程中,采用人工方式校正笔记本电脑壳体间隙存在较大的位置偏差,从而导致产品一致性差的问题,该文提出一种基于机器视觉的笔记本电脑壳体间隙自动调整装置,利用机器视觉软件VisionPro的图像预处理工具、标定工具、卡尺工具等测量准确的间隙数据。利用C#进行上位机开发处理间隙数据并通过TCP/IP通信将调整参数发送给可编程逻辑控制器(PLC),由PLC控制伺服系统精确调节壳体间隙。实验证明,该系统具有较高精度,校正精度可以达到0.1 mm,完全可以投入工厂生产,具有较高的经济价值。

In the notebook computer production process,the large position deviation of the gap of the notebook computer shell is manually corrected,which leads to the problem of poor product consistency.A machine vision-based automatic gap adjustment device for notebook computer casings is proposed,which uses the image preprocessing tools,calibration tools,and calipers tools of the machine vision software VisionPro to obtain accurate gap data.Use C#to develop the upper computer to process the gap data and send the adjustment parameters to the programmable logic controller(PLC)through TCP/IP communication,and the PLC controls the servo system to precisely adjust the shell gap.Experiments have proved that the system has high accuracy,the calibration accuracy can reach 0.1 mm,can be put into factory production,and has high economic value.
