Abstract

Nowadays, TFT-LCD is very popular in life. Many people devoted themselves to research and develop the TFT-LCD process. The purpose is to improve the quality, and to reduce the price. I have been to Usun Company for practice training. Usun is one of the most famous companies in the manufacturing of the TFT-LCD process equipment. In there, I have gained preliminary knowledge of the glass cleaning and polarizer attachment methods. However, the time is limited for studying all equips. Hence, my research only focuses on the automatic glass clean process.
This report includes 5 chapters. Chapter 1 presents an overview about the TFT-LCD (history, structure, principle operator and application) and the requirement of glass surface. Chapter 2 focuses on the analysis of manual glass clean process. Chapter 3 presents several kinds of clean glass machine designs with different structures. Among them, the best design was selected and realized. Chapter 4 focuses on the descriptions of detailed structure and principle of the machine. Finally, In Chapter 5, the experiment result and contribution of this research are present.
Key word: Clean equipment, TFT-LCD Automation.
