FCS系统在贴片机的位置偏差校正中的应用

Application of FCS in chip mounter position deviation correction

准确的定位技术是SMT表面组装生产线上主流设备贴片机的主要性能指标,贴片机的定位系统成为高性能贴片机最为关键的系统之一。以激光校准传感器作为贴片机的视觉定位检测系统,使贴片机自身具有识别贴片位置偏移的自动校正功能,满足小型元件的贴片精度要求,且提高对θ轴马达的强化,实现了面向大型元件的对应能力。结果表明:激光识别自动校正系统FCS在贴片头中的应用,通过非接触定心方式,LED激光多角度照射,光影宽度与切线数据的获取,使用最小二乘法准则完成元件形状分析,位置偏差校正,实现贴片元件精准定位的工艺要求。

Accurate positioning technology is the main performance indicators mainstream SMT production line equipment placement machine. Chip mounter positioning system has become one of the most critical system performance chip mounter. Laser calibration sensor as a visual location detection system chip mounter,so placement machine itself has an identification patch positional shift automatic correction features to meet the requirements of small component placement accuracy,and improve and strengthen the motor of θ axis,to achieve a correspondence ability for large components. The results showed that：automatic calibration of flexible calibration system（ FCS） in the attached application,by way of a non-contact centering,Light- emitting diode（ LED） multi- angle laser light,shadow width tangent data acquisition,using least square method fitting criterion to complete the element shape analysis,correcting positional deviation,to achieve SMD components precise positioning process requirements.
