Laser marker control system

A laser marker control system comprising:

• a personal computer for selectively entering one of an automatic operation mode, a point-teaching mode, and a manual operation mode;
• a programmable logic control coupled to the personal computer, the programmable logic control performing numerical calculations, signal input, status output and control of the carrier table;
• a carrier table coupled to the programmable logic control and linkable to the personal computer in the point-teaching mode, the carrier table serving as a carrier of work pieces to me marked, the carrier table including a grasping device, a work piece support tray, a work piece supply shelf and a work piece collection shelf, and a buzzer and a warning light mounted at suitable locations on the carrier table, the carrier table being controlled by the programmable logic control to have the grasping device move between the work piece supply shelf, the work piece support tray and the work piece collection shelf for picking up, in a one by one fashion, work pieces that are disposed on the work piece supply shelf and at the same time, pick up an already marked work piece that is on the work piece support tray and move the marked work piece to the work piece collection shelf, errors encountered in the system being indicated by the buzzer and the warning light to inform an operator to fix the errors;
• an industrial man-machine interface coupled to the programmable logic control and linkable to the programmable logic control for exchange signals, data and status, the man-machine interface including a touch-control monitor for display of status and indirectly controls the carrier table when linked to the programmable logic control;
• and,
• a laser device linked to the personal computer and generating a laser beam projected toward a work piece to perform a predetermined marking operation, the laser device being linkable to the carrier table in the point-teaching mode.
