POSITIONING MECHANISM OF LARGE-SIZED LIQUID CRYSTAL PANEL

摘要

PURPOSE: To make it possible to accurately position a liquid crystal panel by arranging a positioning air cylinder and a press air cylinder so as to generate rotatory power and again correcting shift by the generated rotatory power. ;CONSTITUTION: When the liquid crystal panel 1 is mounted on a loading plate 2 without being inclined, the liquid crystal panel 1 can be positioned without generating problem. When the panel 1 is mounted on the plate 2 in an inclined state, in two sets of the Y-direction positioning mechanisms arranged on the plate 2, two positioning air cylinders 5a, 5b and two press air cylinders 5c, 5d are arranged in X-direction and a positioning air cylinder 5e and a press air cylinder 5f opposed each other generate couples of forces in the opposite direction with respect to the acting points of the respective forces of both cylinders. The opposite couple of forces becomes the rotatory power in the opposite direction with respect to the panel 1 and only the other couple of forces acts because the panel 1 is inclined and, therefore, the panel 1 is rotated regardless of frictional resistance and angle shift is corrected and the loading plate 2 is accurately positioned.;COPYRIGHT: (C)1995,JPO
