Description
Technical field
The present invention relates to discrete laser process technology, especially a kind of multi-beam synthetic focusing device, be suitable for
In fields such as cold roll laser texturings.
Background technology
Cold-reduced sheet has that thickness and plate shape precision are high, surface quality is good, mechanical property is good, thickness more
The advantage such as thin, applies the widest.Cold-reduced sheet is divided into optic panel and texturing plate by roughness.Texturing plate uses
Texturing Surface of Roll is smooth, and surface topography is by Texturing Surface of Roll copying surface, and roughness is generally large.Relatively
Optic panel, texturing plate is because having more preferable elongation percentage and coated layer adhesion, in automobile, high ferro, aviation
The industries such as space flight, household electrical appliance and packaging for foodstuff have extensive use, are a kind of indispensable important former
Material.
Roller texturing technology carries out texturing to polishing roll exactly so that it is surface has the skill of special appearance
Art.The roller texturing technology industrially obtaining large-scale promotion application at present is shot-peening texturing, electric spark
Texturing and laser roughening, the most more advanced is electric spark texturing and laser roughening.
Electric spark texturing is by being immersed in roll and electrode in insulated working liquid or in the gap of two electrodes
Spray insulated working liquid, two interelectrode gaps are sufficiently small, and electrode applies the pulse of certain amplitude and frequency
Voltage, produces spark discharge, produces a series of micro-molten micro-hole on roller surface.
Laser roughening is divided into CO by the laser instrument kind used2Laser roughening and YAG laser roughening.CO2
Laser roughening passes through continuous CO2The continuous laser that laser instrument sends, chopped device becomes the arteries and veins that frequency is certain
Impulse light, by the most at the uniform velocity moving focus lamp by pulse laser focusing to the roll at the uniform velocity rotated along roll
Surface, makes roller surface fusing, gasification, produces substantial amounts of molten bath, thus formed necessarily at whole roll surface
The micro-hole of hardening having boss in a large number of pattern.YAG laser roughening is by continuous LD pumped YAG lasers warp
Q-switch particular modulation output high-energy-density, the YAG pulse laser of high repetition frequency, by along rolling
Roller the most at the uniform velocity moves focus lamp by pulse laser focusing to the roller surface at the uniform velocity rotated, and makes roller surface
Fusing, gasification, produce substantial amounts of molten bath；Certain ingredients, certain pressure auxiliary gas along certain angle
Side-blowing bath, makes molten bath boss obvious；Roll self conduction of heat makes molten bath cool down rapidly because of fused mass
And Surface hardened layer；Thus the micro-hole of hardening having boss in a large number of certain pattern is formed at whole roll surface.
YAG laser roughening technology is that Inst. of Mechanics, CAS researchs and develops in the nineties, as
Patent of invention " high frequency modulation multy-pulse YAG laser engraving design system and processing method " (ZL
92113223.9).The each to elongation percentage of cold-reduced sheet is regulated to the uniformity in order to increase each of micro-hole distribution,
The two-dimentional controlled distribution technology of Chinese Academy of Sciences's mechanics developed YAG laser roughening, as patent of invention " has
The surface of roller texturing laser-processing system of controlled distribution texturing point " (ZL 00128273.5).In engineering
There is the random distribution in the micro-hole of considerable texturing plate requirement.In order to improve the presentation quality of laser roughening plate,
Controlled random distribution technique is developed, as sent out on the basis of the two dimension controlled distribution technology of Chinese Academy of Sciences's mechanics place
Bright patent " the surface of roller texturing laser-processing system of circumference random texturing point and method " (ZL
200510117158.8)；And for example " the surface of roller texturing laser of random deflection texturing point adds patent of invention
Work system and method " (ZL 200510116750.6).
The laser roughening uniformity in micro-hole and repeatability, service condition, environmental pollution, operating cost etc.
Aspect is all more superior than electric spark texturing.But, in terms of process velocity, laser roughening is compared in electric spark texturing
Advantageously.Same roll, laser roughening needs one hour, and electric spark texturing only may need 20 points
Clock.For laser roughening, micro-pit density of Texturing Surface of Roll is the highest, processes in the case of texturing frequency is constant
Speed is the slowest.Now superior automobile plate, appliance plate micro-pit density more and more higher, highly desirable raising swashs
The process velocity of light texturing.
Electro-discharge Texturing speed is that multi-electrode discharges simultaneously than reason faster.Equally, the most micro-hole is also
Row processing is the inevitable choice improving laser roughening process velocity.
General laser roughening, uses separate unit laser instrument, the scheme of single focus lamp.Use multiple stage laser
Device, the scheme of multiple focus lamp obviously can improve texturing speed.The disadvantage of the program is multiple stage laser
Micro-hole that device produces, relative to the bad control in position, easily produces fatal interference fringe.Its further drawback is
Light channel structure is huger, can the quantity of laser instrument simultaneously can be limited.Also can be by the list of separate unit laser instrument
Shu Guang is divided into multi-beam, focuses on output respectively.Now after beam splitting, the energy of single beam can be limited, and it produces
The position in micro-hole have dependency, the most easily go out striped.
The scheme that after using separate unit laser instrument, beam splitting, single focus lamp focuses on also can improve texturing speed, because of
The multiple micro-hole spacing simultaneously produced is close, is equivalent to one group of micro-hole, is difficult to out striped.The program is
Big shortcoming is the energy constraint in single hole, is only suitable for improving the speed of low roughness texturing.Its further drawback is
Hole spacing in the group of micro-hole is relatively fixed, it is impossible to realize random distribution, have impact on the whole of texturing roll forming looks
Body improves.
Use multi-station laser, close the scheme that after restrainting, single focus lamp focuses on, overcome the energy in single hole not
The problem of foot, should be more satisfactory scheme.It is exclusively used in the quasiconductor of CTP (computer to plate)
Laser module, such as the CTP laser array image-forming module series of Intense, combines the optics device of precision
Part and simple and efficient electronic device interface, it has the arrangement of laser emitters of 64 high reliability,
Each channel interior provides the single-mode laser output of the high reliability of 200mW.The maximum of this device lacks
Point single beam energy is the lowest, it is impossible to texturing.Its further drawback is that each bundle light is fixed relative to position.
