摘要
表面贴装技术生产线中的电子元件实装机通过吸咀内的负压将电子元件吸附,从而实现对电子元器件的拾取和贴装。为便于准确掌握吸咀取料是否成功,通过将负压传感器检测到的压力变化与PMAC板卡上的A/D转换值进行对应并将其量化,对得到的数据利用最小二乘法的原理在MATLAB软件环境下进行多项式拟合,得到最优的数据曲线和数据结果。
SMT production line of electronic components in the real installed by negative pressure of suction nozzle will electronic component adsorption, so as to realize pick-up and placement of electronic components. To accurately grasp the suction nozzle material success, in this paper, through the negative pressure sensors to detect changes in pressure and with PMAC board on the A/D conversion value and the quantification, the corresponding to the data by using the principle of least square method under the environment of MATLAB software, polynomial fitting, get the optimal data curves and data results.
