碩士 === 國立雲林科技大學 === 機械工程技術研究所 === 88 === In this study, the recent applications of Automatic Tool Changer (ATC) were presented, especially on the warehouse type ATC . A Virtual Prototype simulation with mechanism analysis and modal analysis technology was performed to demonstrate the results. First, the kinematic simulations of the multi-link mechanism of the tool transfer unit with ADAMS mechanism software were run to get the kinematic features. And both the kinematic optimization with Newton-Raphson Iteration and Taguchi Method were conducted to acquire a better linkage positioning with lower maximum acceleration of the couple point of the multi-link mechanism. The result of the dynamic features before and after the optima were compared, both optimizations got the similar optimal solutions. Also with Taguchi Method, calculate the optimization of the mechanism with tolerance. Secondly, the modal behaviors of the frame structure of the ATC with FEM were predicted. The results of FEM modal prediction of two Tool Clip with different mesh type and density were compared. Based on the above results, predicting the modal and frequency of the ATC, help to choose the power source working frequency and the suitable structure.
