With the continuous progress of science and technology in China, the supervision of pharmaceuticals in China is no longer the traditional manual supervision mode, but the high-tech intelligent electronic supervision. The electronic drug regulatory code is the label given to each drug by the Chinese government for the implementation of electronic drug regulatory. Each drug electronic supervision code unique, that is, "a code", is the drug id, referred to as the supervision code.
In recent years, with the continuous improvement and improvement of laser technology, various international manufacturing industries have also realized the importance of laser technology. Laser technology can not only increase the technical content of products, but also accelerate the upgrading of products. Driven by the rapid development of the global laser industry, the laser marking machine will lead the drug regulatory code into a new era of high efficiency and environmental protection.
According to the author, before the application of laser technology in the production of drug regulatory code, China's drug identification code is mostly the use of traditional ink inkjet code machine. Ink type printing machine is by controlling the internal gear pump or external supply of compressed gas, by machine to the system in a certain pressure, ink charged drops deflect in deflecting electrode formation deflecting electric field, from the injection nozzle, respectively in different locations medicine package surface, forming a required for a variety of text, pattern and so on.
The label of drug package requires clear data and easy identification of spray code. Because ink inkjet code machine is by electrostatic deflection, so when the static electricity accumulated to a certain extent or will cause sparks, it is easy to cause fire; At the same time, if the grounding is not good, it may lead to poor print quality, ink point splitting is not good, resulting in unclear identification, affecting the appearance of the product; Its ink, solvent, cleaning solution can not be mixed with water, inkjet machine because of the need to accurately charge the ink point, inkjet ink is particularly sensitive to water molecules, improper operation, easy to cause fire; Its ink and solvent are corrosive, easy to touch the skin, eyes, nose, etc.

Compared with traditional ink inkjet machine, laser marking machine is more accurate and environmentally friendly. The laser code injector is a paintbrush with high energy laser beam. The motion track of the paintbrush is controlled by the combination of computer and precision machinery, and the corresponding regulatory code can be accurately printed on the drug packaging box. Laser processing has the characteristics of non-contact, non-pollution, high processing accuracy, it is reported that the current laser code printer has been gradually in the drug regulatory code production has been widely used.
