Title:
BOARD MATERIAL CONVEYOR
Document Type and Number:
Japanese Patent JP3157212
Kind Code:
B2
Abstract:
PURPOSE: To obtain a conveyor, in which waiting time of operator can be shortened without requiring a complex mechanism, by controlling a liquid crystal board to be introduced to a predetermined test position and a liquid crystal board to be moved to a containing position after test, respectively, with no mutual interference.
CONSTITUTION: A manipulator mechanism 2 repeats motions [to move a liquid crystal board of a cassette 1 to a stock mechanism 8] and [to move a liquid board of an X-Y stage mechanism 9 to the cassette 1]. These operations are carried out during test. Operations [to move the liquid crystal board of the X-Y stage mechanism 9 to the cassette 1] and [to move the liquid crystal board of the stock mechanism 8 to the X-Y stage mechanism 9] take place simultaneously in parallel. Consequently, an operator can test next liquid crystal board within a short time after finish of test of one liquid crystal board. Accordingly, a conveyor in which waiting time of operator is shortened without requiring a complex mechanism can be obtained.
