  机器视觉在线检测技术从安装方式上分为固定式和动态式,视觉检测系统从测量的方法上分为采用照相机拍照系统和激光系统两种方式;从应用领域上分为定位检测功能、尺寸检测、型面检测和功能匹配等几个方面。
  Machine vision on-line inspection technology can be divided into fixed type and dynamic type from installation mode; vision inspection system can be divided into two ways: camera photographing system and laser system in terms of measurement method; and it can be divided into positioning detection function, size detection, surface detection and function matching from the application field.
  在自动化汽车生产线中,视觉检测系统必要时需要同机器人匹配应用,并与生产线的PLC控制系统建立联接,以实现测量、检测、定位和识别的功能。
  In the automatic automobile production line, the vision inspection system needs to match with the robot when necessary, and establish the connection with the PLC control system of the production line, so as to realize the functions of measurement, detection, positioning and identification.
  视觉检测系统具有如下特点:采用非接触式测量方式,提高了相应速度,对生产线影响小;具有长时间的稳定、可靠地重复工作的性能,适用于汽车连续化的流水线作业;适合在安全风险高、人机工程恶劣和环境差的区域工作。诸多优点使视觉检测系统在汽车行业中得到了广泛的应用。
  The visual inspection system has the following characteristics: the non-contact measurement method is adopted to improve the corresponding speed, and has little impact on the production line; it has the performance of long-time stable and reliable repeated work, which is suitable for continuous assembly line operation of automobile; it is suitable for working in areas with high safety risk, poor human and mechanical engineering and poor environment. Many advantages make the visual inspection system in the automotive industry has been widely used.
机器视觉检测技术
  视觉测量系统工作原理:使用平面激光照射被测物体表面,采集二维平面数据;使用激光线照射被测物体采集第三维数据;根据采集数据通过专业软件进行分析;通过相关算法得出被测物体或特征的位移、形变以及其他几何特征的变化。
  The working principle of vision measurement system: using plane laser to irradiate the surface of the object to collect two-dimensional plane data; using laser line to irradiate the measured object to collect the third dimensional data; analyzing the collected data through professional software; obtaining the displacement, deformation and other geometric characteristics changes of the measured object or characteristics through relevant algorithms.
  机器人装配精确定位,在现场自动化工位,如顶盖安装、机器人激光焊接、门盖的安装以及自动涂胶等工艺,都需要先进行精确定位,机器人对定位数据进行分析后进行正确的操作,以达到工艺的稳定性。此种定位采取激光测量的方式,通常采用固定方式。
  Robot assembly precise positioning, in the field automation station, such as top cover installation, robot laser welding, door cover installation and automatic gluing and other processes, need to carry out accurate positioning first. The robot will analyze the positioning data and then operate correctly to achieve the stability of the process. This kind of positioning adopts the way of laser measurement, and usually adopts the fixed mode.
  在线门盖型面检测,通常采用照相系统或激光面扫描等对外覆盖件的轮廓或特征进行在线检测,减少了人工搬运、下线的问题,实现100%在线检测,面扫描也是触发式测量设备无法完全替代的检测方法。
  Online door cover profile detection usually uses camera system or laser surface scanning to detect the outline or characteristics of external panel, which reduces the problems of manual handling and offline, and realizes 100% online detection. Surface scanning is also a testing method that trigger measurement equipment cannot completely replace.
  此外,在线检测设备还可以对机器人涂胶的轨迹和位置等进行测量监控,并对轨迹的偏差设定报警限,从而实现自动监控。
  In addition, the online detection equipment can also measure and monitor the trajectory and position of the robot, and set the alarm limit for the deviation of the trajectory, so as to realize the automatic monitoring.
