The anti-fake mark production method and device of scanning》Divisional application.
Technical field
The invention belongs to laser technology application fields, and in particular to a kind of anti-fake mark making dress based on laser scanning
It sets.
Background technology
Anti-counterfeiting technology refers to the measure taken to reach anti-fake purpose, it can accurately differentiate very in a certain range
Puppet is the technology for making product be not easy to be imitated and replicate.Existing anti-fake mark typically in the printing on media of needs or glues
Paste anti-counterfeiting image, coding, bar code or word, such as complicated, beautiful holographic laser antifalsification label.But printing mark relies on
The printing mother matrix (such as bat printing head) made in advance, binding mark are also required to the finished product anti-fake mark for being ready for pasting in advance
Object, two ways cannot flexibly change the anti-fake mark information content, and anti-fake mark is easy to forge, and be also easy to produce abrasion or be stained
It destroys.
In recent years, Laser mark technology has become a kind of new anti-fake mark manufacturing technology.The principle of laser index carving is
Local irradiation is carried out to workpiece using the laser of high-energy density, keeps the chemistry that skin-material vaporized or occurred color change anti-
It answers, to leave permanent marker.However, the anti-fake deficiency of laser index carving is that it is enterprising that laser directly acts on product ontology
Row information marking is limited to product ontology material property, it is difficult to make in bright gay color, beautiful information flag, and anti-counterfeiting characteristic
Place one's entire reliance upon laser index carving technique, and counterfeit product is by purchasing same configuration laser marking machine, it is easy to it is anti-to forge its laser
Pseudo- marking technique.
Invention content
The present invention in view of the above shortcomings of the prior art, provides a kind of anti-fake mark making dress based on laser scanning
It sets.
The present invention is achieved through the following technical solutions:
