Design And Implementation Of A Laser Marking Control Sytem

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 the computer'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 becoming 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 the computer. 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.Through the customer's feedback, we find that the software has reached the desired design requirements. As the marking device separates from the computer, it's really that the marking system becomes more stable, the size smaller, and the cost less. Practice shows that the results of this research, the design concept and the implementation method described in the article are reasonable and practicable which have some reference value for the development of similar systems.
