유리의 동특성을 고려한 기판 레이저 배기홀 가공 장비의 동역학 해석

PDP glass handling system that can handle large size glass fast and accurately is needed in many PDP manufacturing equipments to improve productivity. For exhaust hall drilling equipments that use laser power instead of conventional mechanical drill, more care should be taken in handling the glass due to the holes in the glass. To a predict dynamics of glass handling equipment accurately, interactive analysis that includes both glass and handling mechanisms are required. Due to high brittleness of PDP glass, its material properties such as Young's modulus and Poisson's ratio should be determined through some experimental procedures such as 3 point bending test. The FEM model of the glass was combined to the glass handling mechanism that can interactively analyze elastic behavior of glass under the action of handling mechanism. The impact forces, stress, deflections of the glass was calculated at loading and aligning stages of exhaust hall drilling. This glass and mechanism model can be used to improve design of various glass handling mechanisms.
