Dot-matrix online laser coding technology can realize high-speed and high-precision online coding, which represents the latest development direction of current online coding technology and can provide efficient and feasible product coding solutions for enterprises.
1.The principle of dot - array laser code - printing technology is introduced
Dot-matrix online laser coding technology adopts galvanoscope scanning strategy, and the laser scanning path is controlled by the Angle deflection of X and Y galvanoscopes in the coding system.Dot matrix characters are used for online coding.A lattice character consists of a series of points.When the encoded product moves on the production line, its relative galvanometer scanning has a velocity error V in the opposite direction, which is equal to the speed of the production line.Dot-matrix online laser coding technology obtains this speed error by online monitoring the speed of the production line, and can generate a compensation signal based on this speed error to drive the galvanometer, so as to offset this error.
2.Dot-matrix online laser coding technology has many excellent characteristics:
(1) dot-matrix online laser coding technology adopts galvanoscope scanning strategy. In the scanning process, the galvanoscope is almost free from the influence of external resistance and has the characteristics of fast speed, stable and reliable movement process and accurate positioning.
(2) compared with traditional ink-jet coding technology, dot-matrix online laser coding technology does not need consumables such as ink, and is easy to maintain, cost saving and green.
(3) dot-matrix online laser coding technology USES laser beam with high energy density to act on the target, causing physical or chemical changes on the target surface, so as to obtain high-quality and permanent marks.
(4) dot-matrix online laser coding technology can be easily combined with digital control technology to develop diversified products.
The advantages mentioned above make dot-matrix online laser coding technology has a broad application prospect.
