D的安全气囊装配质量检测装置设计
摘要
随着自动化生产能力的提高,现代工厂中经常会出现需要机械自动检测的场合,那么就非常需要配合视觉系统的机器人来实现这项工作。用视觉检测用 X-Y直角坐标机器人是非常必要的。
本次设计主要包括两个重要的部分。一是对小型直角坐标机器人机械结构的设计,具体包括伺服电机,滚珠丝杠和导轨的选择,实现了 X-Y 直角坐标机器人的直线控制和操作过程;第二部分是对图像采集系统的设计,D摄像机和图像采集软件的设计,以及图像处理的方法和程序设计。本文主要借助于运用MATLAB实现图像的边缘提取,采用BP人工神经网络提高图形识别能力阐述了BP神经网络的基本原理,建立了故障图形识别系统,并进行了实例仿真。
视觉检测用 X-Y直角坐标机器人能够根据其检测结果快速地显示图象,输出数据,发布指令,执行机构可以配合其完成位置调整,好坏筛选,数据统计等自动化流程。与人工视觉相比较,机器视觉的最大优点是精确,快速,可靠,以及信息数字化程度很高。

Design of airbag assembly quality detection device based D
Abstract
With the automation to increase production capacity, modern factory machinery often there is a need to automatically detect the occasion, then a great need for the robot with the visual system to achieve this task. Machine vision is to make the machine was part of eye and brain function, the geometry can be measured automatically, the printing quality of the appearance of defects and product identification, such as the quality of the work of identification. Machine vision systems are generally used in fully automated, reliable and efficient mass production of non-contact detection in the process of identification. Common vision systems typically include: light source, lens, CCD camera, frame grabbers, image processing software, monitors, communication / input and output units, such as. Linear motion modules from the multi-axis motion system called the Cartesian coordinate robots, various sports-axis Cartesian coordinate system usually corresponds to the X axis, Y axis . Cartesian coordinate robot mainly by a number of linear motion units, drive motor, control system and the end of position operator. As a result of munity on the visual detection and rectangular coordinates the increasing demand for robots, it is necessary to the design of visual inspection with XY Cartesian coordinate robot.
The design includes two important parts. First, the small rectangular coordinates of the robot mechanical structure design, including servo motor
