Problems solved by technology

The biggest disadvantage of this device is that the energy of a single beam of light is too low to be textured
Another disadvantage is that the relative position of each beam of light is fixed, and the random distribution of micro pits cannot be realized.

Abstract

The invention provides a multi-beam photosynthesis focusing control system and method. The system comprises an industrial personal computer, at least one laser control device and at least one deflection assembly control device, wherein the industrial personal computer is connected with a controllable distribution interface card and a double-circuit electrical isolation interface card through an AT bus, each laser control device comprises at least two laser drivers, the input ends of the laser drivers are connected with the controllable distribution interface card, the output ends of the laser drivers are connected with lasers, each deflection assembly control device comprises at least one deflection driver, the input ends of the deflection drivers are connected with the double-circuit electrical isolation interface card, and the output ends of the deflection drivers are connected with a deflection motor. According to the technical scheme, the processing speed of laser texturing is increased, and high-energy density texturing processing and irregular distributing in micro-pit sets can be achieved at the same time.

Description

technical field [0001] The invention relates to discrete laser processing control technology, in particular to a multi-beam light synthesis focusing control system and control method, which are suitable for laser texturing of cold rolls and the like. Background technique [0002] Cold-rolled thin steel plate has the advantages of high thickness and shape precision, good surface quality, good mechanical properties, thinner thickness, etc., and is widely used. Cold-rolled sheets are divided into smooth sheets and textured sheets according to their roughness. The textured plate is smoothed by a textured roll, and the surface morphology is copied from the surface of the textured roll, and the roughness is generally large. Compared with plain panels, textured panels are widely used in industries such as automobiles, high-speed rail, aerospace, household appliances, and food packaging because of their better elongation and coating adhesion. They are an indispensable and important...
