Abstract
The marks marked by the laser marker are difficult to wear and easy
anti-counterfeiting, which makes a great role in promoting the improvements of product
quality and grades. The existing laser marker in which the hardware must be installed on
puter’s motherboard and the whole marking process is inseparable from the
computer and reduce the stability of laser marking machines, but also increase the cost
and the size of laser marking machines .
With the further integration of the laser processing technology, it is ing a
trend that laser marking develops into the lighter and the smaller. The marking system
can be divided into two parts: graphics editing and marking control. The work of graphics
editing is achieved on puter. The core of the control software runs on the control
card. LDB file is used to store the data making by the graphics editing and through the
USB device sends the data to the control card, which doesn’t need the involvement of the
computer any longer when it’s marking. Research has focused on the improvement of
oblique-line and correction algorithms, and a control algorithm to control the marking of
the graphics, and analysis the FAT file system of the USB device.
