Design And Realization Of High-generation LCD Panel Automation Production Platform

The development of the LCD(Liquid Crystal Display)industry since the nineteen eighties began,when the main research on basic theory and applied theory.In the seventies of last century,by Japan in the calculator,electronic watch products such as a large number of applications of liquid crystal display technology laid the foundation of the entire industry.To the twenty-first century,liquid crystal display technology to flourish,a large number of applications in computer monitors,televisions,mobile phones,notebooks,not only completely replace the CRT technology,but also beat the plasma display technology,occupy the dominant position in the market.LCD products to the size of the glass substrate as the division,the higher the line,the larger the panel,can cut out the smaller the LCD panel.From the earliest generation line(Generation1),to the current generation of 10 lines(Generation10),the general six generations of lines and above referred to as high on behalf of the line,high generation line,and this paper describes the sixth generation of color filter is high Generation LCD panel.High-generation LCD panel automation production platform is to achieve the LCD panel production machine equipment management,process management,process parameter management,material consumption management,customer order management,operator management and other business operations on a unified platform.The automation platform system runs through the whole process of high-generation LCD panel production,real-time monitoring,management of each piece of glass substrate manufacturing information,the operating status of each machine equipment,the degree of use of each chemical.At the same time,on the basis of this management,real-time or offline production line,machine equipment,glass manufacturing-related data reports,the company's management decision-making to provide data support.High-generation LCD panel automation production platform based on computer integrated manufacturing system,the system to JADF system development platform,providing hundreds of services for customers to use,written by the script into the required Transactions,and finally through the user operation The interface is packaged into a wide variety of operating functions to properly integrate these application functions,presenting a complete manufacturing execution system(MES,Manufacturing Execution System).The key concept of the system design is the computer integrated manufacturing,is all the elements of production to the automated production platform up,because the various elements of production content is different,so different,so the difficulty of system design is "to meet this requirement,We will examine the production lines of the six generation lines,analyze the production requirements and the existing conditions,learn the common standards in the industry,combine the actual situation of the industry,choose the basic production management functions needed to strengthen,remove the dispensable items,New production line requirements.In this paper,the manufacturing system(MES),equipment automatic control system(EAP,Equipment Application Program),database system(EDB,Engineering Database),statistical process control system(SPC,Statistical Process Control),and defect management analysis are developed according to the different requirements of different production factors in LCD panel production.System(DMS,Defect Management System)and other subsystems,in the various subsystems based on a unified database,the use of the same communication protocol smoothly these subsystems to achieve the needs of users to take,the purpose of information sharing.Through the design and implementation of high-generation LCD panel automation production platform,I think the system integrates management,design and manufacturing business to realize the combination of technology,people and enterprise.By using highly developed modern information network technology,Maximizing business efficiency.
