摘要
随着数字信息化时代的来临,利用平板显示器作为数字信息的显示器件已形成趋势。等离子体显示器(PDP)是实现大屏幕壁挂式显示的理想器件,与其它平板显示器件相比,具有厚度薄、重量轻、屏幕大、视角宽、响应快等优点。本次选题是基于四川长虹电器股份有限公司的42"和50"的PDP显示器生产线的对合机设备,通过自动化的控制,实现PDP显示器前后玻璃基板的自动对准。该项目得到国家发改委和工信部的大力支持。
本文首先介绍了PDP显示器的工作原理以及AC-PDP彩色显示器的生产工艺。然后,对PDP对合机设备的控制系统的软硬件进行了详细的设计。详细论述了电气系统的硬件设计,主要完成的功能及技术指标,硬件实现,各个执行机构的控制方法;对整个系统的软件进行了设计,主要包括自动模式方式下的动作流程及手动模式下的控制方法。最后,对该设备中关键的部分——视觉定位系统,进行了详细的设计。
本文研究了一种采用图像作为检测信号,实现前、后玻璃基板之间的精密定位的定位方案。通过CCD摄像机采集玻璃基板上做好的Mark标记,放大后送给视觉定位系统处理,得出前后玻璃基板之间的位移差,驱动视觉定位平台动作,实现X-Y-θ三个自由度的精密定位,定位精度为±5μm。最后,对Mark标记的中心定位的方法进行了研究。
With the advent of digital information age, the use of flat-panel display as a digital information display device has become the trend. Plasma display panel (PDP) is an ideal device to achieve large-screen wall-mounted display. When compared with others, it has many advantages such as thin in thickness, light in weight, large screen, wide viewing angle, quick response and so on. This paper is based on the assembly machine equipment, which is one of equipments in 42" and 50" PDP display production line of Sichuan Changhong Electric Co. Ltd. It achieves the purpose of the automatic alignment of the front and the back PDP display glass substrates. The project got much support from the National Development and Reform Committee and the Industry and Information Technology Ministry.
This paper introduces the principle of PDP displays and the production processes of AC-PDP color display at first. Then, it gives the detailed hardware design and software design of the control system in the PDP assembly machine. The hardware design mainly includes a detailed discussion of the electrical system design, the main features and specifications, hardware implementation and the control methods of various implementing agencies. And the software design of the whole control system mainly includes the action processes in auto mode and the control methods in manual mode. Finally, it studies the visual positioning system, which is a key part of the device.
This paper studies a scheme which uses the image as a detection signal, to achieve the precise positioning between the front and the back PDP glass substrates. By collecting and amplifying the marks on the front and the back glass substrates through the CCD cameras, the visual positioning system will automatically calculate the displacement difference between the front and the back glass substrates. And then the visual positioning system drives the visual positioning platform to achieve the precision positioning in three degrees of freedom which are X, Y andθ. The positioning accuracy is±5μm . Finally, this paper studies the method of finding the center location of the mark and makes the simulation.
