Abstract

The invention provides a multi-beam synthesizing and focusing device. The multi-beam synthesizing and focusing device comprises a focusing assembly and at least one multi-beam synthesizing assembly; the multi-beam synthesizing assembly is used for synthesizing a plurality of incident light beams in different directions, and comprises at least two lasers, optical fibers and collimators with the same number as that of the lasers, and a deflection assembly; each optical fiber is connected with one laser; each collimator is connected with one optical fiber; the deflection assembly comprises at least one reflecting mirror used for changing the directions of light beams emitted from the collimators; the focusing assembly is used for converging parallel light beams, and comprises a lens frame and a focusing lens which is arranged in the lens frame. According to the multi-beam synthesizing and focusing device, a plurality of light beams in different directions can be synthesized into a plurality of parallel light beams at included angles of 0 to 30 degrees and are converged finally through the focusing lens; micro-pit groups are generated on a roller surface simultaneously or at different times, and roughened areas within a unit time are increased, so that the laser roughening machining speed can be improved; regular and irregular distribution parameters are conveniently set; stripes are not easily generated on a roughened roller surface.

Description

technical field [0001] The invention relates to discrete laser processing technology, in particular to a multi-beam light synthesis focusing device, which is suitable for the fields of 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 raw material. [000...
