Abstract
A laser marker control system includes a personal computer, a programmable logic control (PLC), a movable carrier table, an industrial man-machine interface and a laser device. The personal computer is linked to the PLC to control the laser device and is linked to the carrier table in a point-teaching operation. The PLC is provided for numeral calculation, signal input, status output and control of the carrier table, and provides signal, data and status exchange when linked to the man-machine interface. The carrier table is the carrier of the work piece, controlled by the PLC to change the position thereof. In the point-teaching operation, the carrier table is linked to the personal computer and the PLC. The man-machine interface is a touch-control monitor for status display and may indirectly control the carrier table when linked to the PLC. The laser device which generates and emits a laser beam for marking operation is connected to the PLC. The laser device is linked to the carrier table in the point-teaching operation. The control system of the present invention may be used to replace the manual control and may "learn" to perform marking operation on work pieces of different sp…
