Carriage rail width automatic adjustment manner and its device null of automatic check

摘要

PROBLEM TO BE SOLVED: To provide a conveyance reference correcting function which is not restrained by the position of the conveyance reference surface of a conveyer with a carrying-in/-out mechanism driven by a program that permits the conveyance reference surface of an automatic inspection device to be moved within the range of maximum board width of the conveyer. ;SOLUTION: A stationary conveyance rail 3a in the inspection table 3 of an automatic inspection device is made to meet the maximum traveling positions of moving rails 6b, 7b in conveyance devices 6, 7. The interval between the stationary conveyance rail 3a and the moving conveyance rails 3b of the inspection table is made to meet each other in a condition where the interval to the stationary rails 6a, 7a changes because of the traveling of the moving rail. Then, or at the same time, by moving the inspection table, the stationary conveyance rail is made to meet the moving rail. A carrying-in/out mechanism driven by a program which permits the conveyance datum surface of the automatic inspection device to move in the range of the maximum base plate width of a conveyer offers a conveyance reference correcting function which is not restrained by the location of the conveyance datum surface.;COPYRIGHT: (C)1997,JPO
