Description of drawings
Fig. 1 is the structural representation of embodiment of the invention institute operative installations.
The specific embodiment
In detail the preferred embodiments of the present invention are described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, realize that this aluminium foil laser cutting parameter needs one to unreel equipment 1 and a rolling equipment 2, before cutting, at first aluminium foil 4 is passed and be rolled onto on the equipment of unreeling 1, by being set, laser instrument adjusts the relevant parameter of laser then, according to the different positions of adjusting laser instrument 3 of required aluminium foil width, the focal position of adjusting laser instrument 3 simultaneously can act on the aluminium foil 4 laser, then laser instrument 3 bright dippings are cut the end of aluminium foil 4, end with the aluminium foil of well cutting is fixed on the rolling equipment 2 then, can drive aluminium foils 4 by equipment of unreeling 1 and rolling equipment 2 like this and move.One side of aluminium foil 4 also is provided with a blowing nozzle 5, and blowing nozzle 5 is blown to the cutting section of aluminium foil in cutting, makes the cutting section cooling cooling of aluminium foil.
Laser instrument 3 can adopt optical fiber laser, ruby laser or royal purple laser instrument.The laser power that adopts optical fiber laser to send should be controlled between the 10-100W, and the laser power that adopts ruby laser or royal purple laser instrument to send should be controlled between the 10-30W, and its occurrence should be regulated variation according to the thickness of aluminium foil.The laser frequency that laser instrument 3 sends will directly have influence on the roughness of aluminium foil cutting section, and the color to section is also influential, under the situation of other parameter constants, the higher then section of frequency is smooth, color be golden yellow or yellow in band black, degree of oxidation is higher, and laser frequency generally is controlled in the scope of 10-100KHz and cuts debugging.
The laser action that laser instrument 3 produces can adopt positive Jiao or two kinds of methods of out of focus to cut when cutting on aluminium foil.Adopting just eager method of cutting is exactly that the focus of the laser that sends of laser instrument just is positioned on the aluminium foil, adopts this method to cut, cutting section blackout but comparatively smooth.The method that adopts the out of focus cutting is exactly the position that the focus of the laser that sends of laser instrument is higher or lower than aluminium foil, adopts this method to cut, and cutting section turns white but shows coarse slightly.
The gas that blowing nozzle 5 blows out can be nitrogen, compressed air or oxygen, select which kind of gas to decide on specific requirement, need not oxidation as the aluminium foil cutting section, then need use nitrogen, oxidation as the aluminium foil cutting section needs, then can adopt compressed air to blow, higher as the needs degree of oxidation, then adopt the oxygen cooling of blowing.Air-blowing quantity is also very important, and the pressure of air blowing generally is controlled at 0.1-0.6Mpa, and occurrence is decided on effect, such as requiring section more in vain, and the not high air-blowing quantity that then reduces of degree of oxidation, otherwise, then increase air-blowing quantity.Blowing nozzle 5 also can influence the cutting section effect from the distance of aluminium foil 4, because this, then causes the aluminium foil distortion too by force apart from the pressure that directly influences air-blowing quantity and breaks product rejection; Oxidation is insufficient again too, influences product quality, and valve 5 should be controlled between the 10-25mm apart from the distance of aluminium foil 4, and occurrence can require according to the degree of oxidation of aluminium foil cutting section to decide.
In cutting process, if the speed that moves of aluminium foil is too fast, aluminium foil has the play phenomenon, cause the deep mixed of laser cutting to cause easily, if particularly occur in the cutting process not cutting situation, burr appears just aluminium foil can be pulled, directly cause scrapping of aluminium foil.And if the speed that moves of aluminium foil is slow excessively, then can have influence on the efficient of aluminium foil cutting, therefore also can exert an influence to the stationarity of machine and the tightness of coiled strip simultaneously, unreel equipment and rolling equipment and drive the speed that aluminium foil moves and generally be controlled between the 10-70m/min.
Again as shown in Figure 1, front one side in aluminium foil 4 cuttings is provided with a front smoking dust-arrester 6, side at aluminium foil 4 back sides is provided with a back side smoking dust-arrester 7, in the laser cutting process of aluminium foil, front smoking dust-arrester 6, back side smoking dust-arrester 7 are worked simultaneously, and the flue dust that produces in the cutting process is carried out adsorption removal, make the environment of working site more clean, simultaneously can prevent that also flue dust is adsorbed on the aluminium foil cutting section, influence the quality of aluminium foil cutting.
This aluminium foil laser cutting parameter cuts aluminium foil by laser, make aluminium foil hot melt fracture at high temperature, just can not produce the zigzag burr at the plane of disruption like this, the cutter that has solved common cutter cutting machine is easy to wear, cutting section has the phenomenon of zigzag burr, thereby for electric capacity manufacture craft process has afterwards been saved raw material, also reduced the volume of capacitor, the more important thing is the aluminium foil that adopts this technology cutting, particularly there is point discharge phenomenon hardly in the aluminium foil that carries out after the oxidation of cutting section, avoid electric capacity owing to 1 bad problem of scrapping entire product like this, improved the yield rate of electric capacity greatly.
