Ultrahigh-speed blockchain laser engraving system

Abstract

The invention discloses an ultrahigh-speed blockchain laser engraving system. The ultrahigh-speed blockchain laser engraving system is used for solving the problem of repeatability of each microstructure through a telecentric lens and the problem that in the scanning process of a laser scanner, the processing bending phenomenon is caused by distortion of graphs, and used for achieving the effect that the focal length is changed with the change of the product thickness, and thus consistency of the processing focal length is ensured on the product surface. The ultrahigh-speed blockchain laser engraving system comprises a graph input module, a processor, a laser emitting module, the laser scanner, the telecentric lens, a to-be-engraved LGP, a linear module, a position collecting module, an angle collecting module, a U-shaped compensation module and an automatic focal length adjusting module. The compensation angle can be calculated through the formula (please see the specifications for the formula) and theta 2=theta<y>, thus the system error is subjected to angle compensation, and engraving precision is improved; and the telecentric lens is adopted to enable a laser beam to verticallyirradiate on the surface of the to-be-engraved LGP, so that the problem that an existing F-theta lens irradiates on the product surface obliquely and consequently, each microstructure occurs repetitively is solved.

Description

technical field [0001] The invention relates to the technical field of laser engraving, in particular to an ultra-high-speed blockchain laser engraving system. Background technique [0002] Laser scanners are also called laser galvanometers, which consist of X-Y optical scanning heads, electronic drive amplifiers and optical mirrors. The signal provided by the computer controller drives the optical scanning head through the driving amplifier circuit, so as to control the deflection of the laser beam on the X-Y plane. In the laser demonstration system, the waveform of optical scanning is a vector scanning, and the scanning speed of the system determines the stability of the laser graphics. In recent years, people have developed high-speed scanners, the scanning speed reaches 45000 points / second, so it can demonstrate complex laser animation. Scanning principle: The scanning pattern is a two-dimensional effect pattern, so the scanning motor is controlled by two motors, X a...

Problems solved by technology

[0003] However, existing laser scanners use a flat-field focusing lens (F-theta lens), and when the laser beam passes through the flat-field focusing lens, it will irradiate obliquely on the surface of the product, which will cause repeatability problems for each microstructure; laser scanners There is a distortion of the graphics during the scanning process, and it is necessary to compensate the angle of the graphics
