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

An apparatus for detecting a starting signal in an automatic facility capable of detecting an introduction and a position of a pallet having a cathode-ray tube assembly and is carried by a conveyor belt, and providing a pattern generated by a measuring device through a movable connector and a secured connector to the cathode-ray tube assembly to examine and adjust the cathode-ray tube assembly, comprising:

• stoppers being mounted on a frame of the conveyor belt in a direction of moving the pallet and are lowered and raised by a pneumatic pressure, the stoppers including first and second stoppers;
• a detector being disposed in place on the frame of the conveyor belt to be spaced at a predetermined distance from the first stopper, the detector detecting the introduction and the position of the pallet;
• and
• a controller 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, the controller 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.

A method, comprising:

• setting an initial position of a first stopper and a second stopper, the first stopper and second stopper being mounted on a frame of a conveyor belt;
• detecting automatically an introduction of and a position of a pallet on the conveyor belt;
• adjusting the position of the first and second stoppers in the introduction of the pallet to connect a movable connector to a secured connector of the pallet in a predetermined period;
• providing a pattern for a cathode-ray tube assembly through the movable connector as to display the pattern for examining and adjusting the cathode-ray tube;
• and
• separating the movable connector from the secured connector after examining the display of the cathode-ray tube assemble and resetting the first and second stoppers to the initial position.
