結合RFID及平板電腦於TFT-LCD生產設備巡檢之應用

Abstract

面板產業為資本密集、技術密集的產業，且設備折舊費用高，公司為了降低固定成本高、維持競爭力，就必須最大化設備綜合效率（OEE）。為使OEE最大化，設備預防保養是不可或缺的作業。而設備巡檢作業是工廠執行預防保養之基本項目，正確及徹底地執行設備巡檢，不但可儘早發現設備之異常並進行異常處理，更可減少異常品的數量及公司的損失。傳統巡檢作業是以紙本表單為記錄方式，但紙本表單始終存在著無法確認是否有確實到位執行點檢、巡檢記錄查詢及利用不便等缺點。因此，本研究結合RFID的辨識功能，以及平板電腦的行動功能，開發了一套運用於面板廠日常巡檢作業之行動巡查點檢系統，期望能改善巡檢作業的執行度與正確性，進一步降低設備異常的時間及異常品的數量，以提升公司之競爭力。

TFT-LCD industry is capital-intensive and technology-intensive. It also has high equipment depreciation costs. In order to reduce the fixed costs and keep the market competitiveness, the TFT-LCD company has to maximize the Overall Equipment Effectiveness (OEE). Checking equipments is the basic job of machine preventive maintenance to keep the OEE maximized. Correct and complete implementing the equipment checking can not only detect the abnormal in the early stage, but also reduce the quantity of abnormal product and loss. The traditional checking operation utilizes paper form to record, therefore it is impossible to confirm the action is certainty done. Moreover paper form has some disadvantages, for example, human mistake, incorrect checking the equipment, inconvenient querying the historical data ... Therefore, this thesis integrates RFID and Tablet Computer‘s functions to develop a mobile checking system for the production equipment of TFT-LCD to improve it degree of implementation and exactitude of checking, further reduce the equipment downtime and the quantity of abnormal product, and enhance the company’s competitiveness.
