The system realized the operation of automatic alignment and assembly of lcd substrate with assembly precision of + 10u and assembly speed of 2 pair per minute 该系统实现了对14 " 14 " 16 " 16 "大小lcd基板的自动对位贴合操作,其贴合精度达10 m ,对位贴合速度达2对分钟。
Next , based on the adjusting model the automatic focusing and automatic alignment about the pixel devices is realized on the platform of the large screen rear projection display system 然后,以大屏幕液晶投影三色会聚装置为实验平台,针对所建立的数学模型实现了自动三色会聚。
To solve the problems of low precision , low effectiveness and too high labor intensity caused by manual operation in the processes of alignment and assembly , the automatic alignment and assembly system of lcd were developed 为解决lcd基板对位贴合过程中因人工操作造成的对位精度差、效率低及劳动强度过高等问题,研制了lcd基板自动对位贴合系统。
The paper show the principle and configuration of the system , and present in detail the design idea and technique of its hardware and software as well as the automatic alignment arithmetic and image - processing 给出了其组成及工作原理,详述了该系统硬件的设计方法及原理,给出了系统软件设计的思路和方法,详述了自动对位算法和对位标记的图象自动识别方法。
In this thesis , the work on automatic alignment system is as follows : firstly , after the methods and optical systems for alignment whose are used commonly now are discussed , a new die leveling method based on auto - focus is presented for the flip chip bonder . auto - focus is completed by estimating from images ; die leveling is completed by focusing for several feature locations 本文针对倒装贴片机的自动对准系统开展了以下几方面的工作:首先在讨论了现有的对准方法和自动贴片机的对准光路系统基础上,针对贴片机实际应用环境,提出基于多点自动对焦的芯片调平方法。
