MES project case of TFT-LCD glass rear engineering section of Yakong

1. Project Overview

The TFT glass post-engineering project is the first domestic production line of G8.5 TFT-LCD glass substrates with float technology. High-generation glass realizes localization for the first time, breaking the situation that high-end TFT-LCD glass substrates rely on imports. The key technology of the “stuck neck” has filled the domestic gap.

In view of the new production line and new technology, there are insufficient information technology, insufficient transparency of the production process, lax control of process quality, difficulty in product traceability, difficult analysis and statistics of equipment status, failure to handle abnormalities in time, low production efficiency, and islands of information For other issues, it is necessary to introduce the MES system to comprehensively control all factory resources such as production line planning and scheduling, materials, processes, quality, equipment, etc., so that production can be controlled, plans are truly implemented, and the intelligent level of enterprise manufacturing is improved.

2. Project implementation

The project involves a production line, mainly including 7 processes, a total of more than 80 equipment, more than 10,000 variable points. Through the implementation of this system, the material flow and information flow have been opened up. Through the accurate collection of data during the production process, the transparency of the production process has been realized, the production process has been optimized, and the rapid response to abnormalities such as equipment and technology can be traced back to the product. Various statistical reports and intuitive charts to satisfy management and business, thereby improving production efficiency and comprehensively controlling the production process.

Partial implementation effect

Production monitoring kanban: real-time display of production progress, workshop energy consumption, equipment information and material information, and overall understanding of workshop production information.


Production line status: Dynamically simulate the production process, display product process data in real time, and make the production process more transparent.

Quality analysis: statistical analysis of defect rankings, the number of different levels of defects, and more comprehensive quality management

3. Benefit analysis

Through the implementation of the MES system of the KingFusion platform of Asia Control, the connection between the process control layer of the production site and the enterprise operation management layer is opened, and the automation of the information flow between the production process system and the enterprise operation system is promoted, and the enterprise gradually accumulates the production process, quality and cost. Data information such as enterprise product design data, product maintenance data, etc. are connected to form enterprise production and product big data resources. Through the analysis and utilization of data, the network, digital, and intelligent level of enterprise manufacturing is improved, in order to realize intelligent manufacturing. Lay the foundation.

  • Improve customer satisfaction and establish an effective monitoring-feedback-tracing system for each link in the production process;
  • Provide production order management, material management, equipment and parts management, real-time monitoring of process parameters, statistical analysis of quality problems, production process early warning and alarm, on-site production visualization and other functions;
  • Through real-time simulation of the production process of the production line, the workshop production is made transparent, and the overall production status of the workshop is intuitively displayed;
  • Establish a complete work order-product-material forward and reverse traceability system to trace every piece of data in the product production process and provide true and reliable original production records;
  • Realize comprehensive quality management, real-time monitoring of workshop production process data (process, equipment, environment, etc.), and production abnormalities;
  • Realize data transfer with ERP, WMS, EMS and other systems;
  • The system is developed based on modeling ideas, and the industry has the characteristics of management standardization, rapid migration and reuse.
