摘要
点胶机在工作过程中主要保证的是被加工电路板的重复定位精度,该精度的大小直接影响点胶机的应用领域,故建立点胶机定位误差的测试系统十分必要。测试系统是基于实验室虚拟工作平台建立的,它提供了实现仪器编程和数据采集系统的便捷途径。使用它进行原理研究、设计、测试并实现仪器系统时,可大大提高工作效率。故以LabVIEW软件为平台,设计了点胶机定位精度的测试数据采集系统。详细介绍了利用LabVIEW提供NI-DAQmx数据采集驱动程序,结合数据采集设备NI-USB6251实现数据采集的方法。该装置可以实现在计算机上动态显示、存储信号数据。并以步进电机驱动的点胶机为例,利用此系统测试重复定位误差。
The most important point is to assure the positioning accuracy of circuit board in the process of cementing machine working. The positioning accuracy will decide its application area., so it is necessary to base a set of testing system. The positioning accuracy testing system is based on LabVIEW. It provide a access way to data acquisition and instrument programming. Also it can improve the work efficiency. Utilize the LabVIEW, design the data acquisition system of cementing machine＇ s positioning accruracy. The article particular introduce how to utilize LabVIEW and its driver （NI-DAQmx） for DAQ device such as NI-USB6251 design the data acquisition system. This set can display dynamic on computer and storage the data. And for the example of cementing machine drived by the step-servo motor, test the positioning error.
