The Study Of Laser Marking-on-the-fling

Laser marking technology is an important division in laser application technology. It has gradually becoming important marking methods with its conspicuous marking effect and rapidly marking speed. Nowadays, laser marking technology has became a effective marking method of many substances such as plastic, quartz, china, metal and so on. Recently, there are many new developments in laser marking technology. Laser marking-on-the-fling is a remarkable domain in these developments. The technology of laser marking-of-the-fling is a dynamic marking method on the product line, not only enhancing the productivity rapidly, but also having the purpose of preventing forging. The technology of marking-on-the-fling scopes several disciplines such as optics, machinery, electronics, computer and sensing, which is a rising technology with all-round. The target of our research is to develop a special laser marking-on-the-fling system using for the marking of the producing batch and the producing dates in product line of cigarette, beer, medicine, drinking and so on. In this thesis, we introduce the main buildup of the system based on a brief introduction to the basic theory of laser marking, and we research the compensating for displacement real time in dynamic marking related to actual product line. During the research, we chose the RF GEM-30A CO2 LASER to leave the water-cooling out which have a good beam and long life span. For the purpose of higher speed, we selected the RTC3 board based on the DSP technology and a scanner with a higher speed besides optimizing the software, and we got a marking speed of 500 letters per second. The software of laser marking on-the-fling is a special table for our system. The software has a friendly interface. The users can put the laser parameter, scanner parameter and the fly parameter into the software in order to the system well running. We also summarized the testing and experimenting and analyzed the all parameters in our paper, fulfill the purpose of the research. And we also made much prearrangement for the building in and adjusting of the system in field.
