碩士 === 逢甲大學 === 材料與製造工程所 === 95 === In recent years, with the development of the liquid crystal display of a new generation, the base plate is becoming larger and larger in size. As a result, the related fabrication process and automation equipment is also changing a lot, and the way to move the base plate has been steadily improved through innovation. Traditionally, a prototype of the moving machine was first developed to simulate practically the interactive action between the robot-fork and the cassette, and it was then modified to avoid all the possible interference problems encountered during the test. However, due to time restriction, it is usually impossible to wait too long for the test result when a company confronts severe competition. In this study, the CAE software, COSMOS╱Works, was used to investigate the relative deflection between the robot-fork and its corresponding casette. The computed results was validated by experimental data and the design time period was shortened. It aims to speed the design of a robot-fork which meets the safety requirement prescribed between the robot-fork and the cassette. The error is smaller than 10 % in compare with measuring and analysis, proving this method is feasible.The conclusions are summarized as follows: 1.The safety of cassette can be improved more than 30 % by adding a reinforce layer to the Robot-fork. 2.The replacement of aluminium alloy by CFRP can reduce the deflection more than 50 %, and thus further satisfy the safety requirement of the corresponding cassette. 3.If the Robot-fork supporting base has not been included in the analysis, it will not only influence the trend of the computed result, but also underestimate 20 % of the total deflection in the Robot-fork system.
