Title: Apparatus and method for detecting a starting signal in an automatic facility

Abstract: Disclosed is an apparatus and a method for detecting a starting signal in an automatic facility, in which a pattern is automatically provided to a cathode-ray tube assembly on a pallet to examine and adjust the cathode-ray tube assembly. According to an aspect of the present intention, the apparatus for detecting a starting signal in an automatic facility, includes first and second stoppers that are mounted on a frame of the conveyor belt in a direction of moving the pallet and are lowered and raised by a pneumatic pressure, a detector which is disposed in place on the frame of the conveyor belt to be spaced at a predetermined distance from the first stopper, for detecting the introduction and the position of the pallet, and a controller for raising the first and second stoppers using the pneumatic pressure to stop the pallet and to prevent the introduction of a next pallet when the detector detects the introduction of the pallet, for controlling the measuring device to provide the pattern for the examination and the adjustment through the secured connector to the cathode-ray tube assembly when the detector detects the position of the pallet, and then for lowering the first and second stoppers. Accordingly, it is possible to control the first and second stoppers simultaneously, thereby preventing errors and improving a productivity of products.
