基于机器视觉的机械手装配系统设计

Design of a Robot Assembly Inspection System Based on Machine Vision

摘要:

为了解决工业生产过程中料板的自动装配问题,提出了一种基于机器视觉的机械手定位装配检测系统,建立了实验平台。系统通过工业相机对料盘进行图像采集,将所采集的信息传送给工控机,借助图像处理程序,采用图像预处理实现了对图像的降噪,结合BLOB分析对图像特征进行了提取,获得了料盘上装配孔的位置信息,通过控制机械手动作,移动到装配位置,旋转相应角度,实现料板的自动定位装配。实验结果表明,该系统装配准确度高,误差小,满足了工业上的要求。

Abstract:

In order to solve the problem of the material board automatic assembly during manufacturing process, an inspection system of robot positioning assembly based on machine vision is proposed and experience platform is made. The system grabs the images of the tray by using the industry camera, transports the image information to industry computer, uses the image processing program to reduce the noise by pretreatment, extracts the image features by using blob analysis, recognizes the hole position of the material board, and controls the robot to move to the correct position achieving automatic position assembly. Experience result shows the system has a high accuracy and meets the need of the industry.
