Laser marking machine is an industrial marking equipment, and here we are saying is laser marking machine control, there are two ways, one is the use of single-chip, low price, small size is not a small advantage, while the other species use microcomputer control advantage lies in easy connection with other systems as well as the marking of the recording process, and most started using the microcomputer to control the graphics processing and graphics rendering in the present, as well as the marking of the use of database management, and this system control accuracy becomes an issue, because it depends on the quality of the product marking, following this brief introduction to the system.

This system consists of computer (including control system software) and laser marking machine composed of two parts, connected through an interface circuit board between the two, the overall structure is shown below. Laser marking machine is mainly driven by the circuit, the laser head laser generator and drag a stepping motor and other components. A port interface circuit high and low four four switches are used to control the laser head in the X-axis and Y-axis stepper motor movement, port B is used to control the laser port. Controlled by the software initialization module, the database module, single file marking module, the output control module, whose functions are as follows:

Initialization module: The main marking is used to adjust output parameters, such as marking speed, idling speed, output proportional compensation delay.

Database modules: marking the completion of data entry and modification, deletion. Database records by date and serial number as the keyword.

Single file marking modules: mainly used for marking user generated output PLT files.

Output control module: This module is mainly used by the interface card output control marking.
