  • 公差資訊對產品品質與穩定是很重要一環,然而產品生產過程中,從產品的設計到製造與檢驗都必須加以考量,並須維持其一貫性。在產品大量及多樣化的需求下,產品的互換性是很重要的原則,而公差就是其考慮的重點之一,尤其在零件裝配時,公差就是影響裝配是否一致程度的最大因素。本研究中主要是以液晶面板背光模組零件設計組裝公差分析研究為主,運用RevCAD電腦模擬軟體,進行模組組裝公差設計模擬與分析,利用模擬軟體公差分配與分析模擬功能,以及零件材料特性的不同,在不同材料上利用公差限制方法,作合理的的公差設計與分配,以達到改善產品組裝良率與品質提升。


    The tolerance information plays an important role on the quality uniformity and stability of the finished products. It should be kept in mind to maintain the tolerance continuity from initial product design to final product verification. Nowadays, customarized products are required to exchange their components to satisfy the individual customer’s demands and to accelerate the developing process simultaneously. The determinant factor for the exchangeability and components is the inter-component tolerance consideration. Especially, the critical tolerances of some key parts are the major factors to decide the uniformity of the product assembled. The objective of this study is to conduct a computer-aided tolerance analysis for the back light modules used in the liquid crystal panel. The tolerance allocation, analysis simulation functions and designated material characteristics are applied to each ingredient component. The simulation result can approach a reasonable set of tolerance design and allocation for each component under the prescribed limitation on the assembled components. The in-house allocation analysis software- RevCAD is used in this study. This simulation software is proved to be a powerful tool to increase the design efficiency and to improve the assembled product quality.
