基于松下FPX的VFD测试系统设计

论文编号:ZD1070    论文字数:8202,页数:31

摘  要
    VFD出厂前要进行多项检测包括：高压检测，单笔扫描，多笔扫描，栅网扫描，全亮扫描。传统的检测系统要通过两个检测仪器，一个检测完之后要拆装到另外一个仪器进行余下的检测，过程繁琐容易出错。本系统的主要目的就是利用松下FPX做为控制器将两个仪器结合在一起省去了中间拆装的过程，从而提高工作效率，也减少了错误率，减轻了工人的工作强度。
 真空荧光显示屏(VFD)利用电子撞击荧光粉，使荧光粉发光，是一种自身发光显示器件。由于它可以做多色彩显示，亮度高。VFD薄膜基板要求导电线路宽度和线间距小于0.03mm，因此极易造成产品的连线与断线，由于这两种原因造成产品的报废占产品不良的80%以上。

Abstract
VFD need to have a number of factory testing to include: high-pressure testing, a single scan, multiple scans, scan grid, allLight scanning. Detection system to the traditional detection through two machines, one to disassembly after testing to another instrumentDetection of the remaining, the process cumbersome, prone to error. The main purpose of the system is to use as a controller Panasonic FPX two-yee Save a device combining the middle of the process of disassembly, thereby enhancing work efficiency and also reduce the error rate, reduced workersWork intensity.
The vacuum fluorescence display monitor (VFD) using electronic impact phosphor, so that light-emitting phosphor is a self-luminous display.Because it can do more than color display, high brightness. Conductive thin-film substrate requirements VFD line width and line spacing less than 0.03mm, Resulting product is therefore vulnerable to connect with the disconnected, as the products of these two causes accounted for the end-of-life products for more than 80% of non-performing.
