Abstract
The invention discloses a laser cutting method for a lens. In the method, the lens is cut on a lens blank along a predetermined track by using laser light; the predetermined track comprises an internal cutting line of the lens defined on the lens blank and at least one external cutting line for further distinguishing scraps positioned at the periphery of the lens; one end of the external cutting line is connected with the internal cutting line, and the other end of the external cutting line extends out of the edge of the scraps; the depth of the predetermined track on the lens track is smaller than the thickness of the lens; and after cutting along the predetermined track is performed, the lens blank is cooled immediately and the scraps are cleared along the predetermined track. According to the method, expansion of the lens caused by heat absorption is released in the cutting process by using the external cutting line; the scraps are not cut, so that heat absorbed by the lens is not too high; and heat absorbed by the lens can be taken away in time in the cooling step, and the scraps can be cleared easily along the predetermined track.
Description
Technical field
The present invention relates to laser cutting technique field, more particularly, relate to a kind of laser cutting method of eyeglass.
Background technology
The lens cutting of traditional approach is mainly the hard contact of machinery processing mode, as adopted glass cutter cutting, saw blade cutting, diamond cut etc.In adopting the hard contact of machinery processing mode process, because lens bears larger mechanical stress, easily deform.Particularly glass lens, even can produce slight crack in process, causes product rejection.Because machining mode is difficult to realize automation, therefore its process velocity is slow, production efficiency is lower.
And contactless Laser cutting, can make lens in process without bearing mechanical stress, meanwhile, Laser Processing speed is fast, precision is high, can convert arbitrarily machining locus, seems to solve the defect that above-mentioned machinery contacts processing mode firmly.But experiment shows, while adopting Laser cutting eyeglass, the irrational accumulation of heat during due to cut-out, and all leftover bits and pieces of material restriction that eyeglass is expanded in the situation of being heated, the probability that makes eyeglass produce slight crack so that scrap is very high, thereby this option of laser cutting lens is directly got rid of by those skilled in the art.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of laser cutting method of eyeglass, and it can reduce eyeglass defect rate, and significantly enhances productivity.
For solving the problems of the technologies described above, technical scheme of the present invention is: the laser cutting method that a kind of eyeglass is provided, adopt laser along desired trajectory, on lens blank, to cut out eyeglass, described desired trajectory is included in the inside line of cut that defines eyeglass on lens blank, and at least one pair of waste material that is positioned at lens periphery done the outside line of cut of further differentiation, described outside line of cut one end is connected with described inner line of cut, the other end extends the edge of described waste material, the degree of depth of described desired trajectory on lens blank is less than the thickness of described eyeglass, after described desired trajectory cutting, lens blank is carried out immediately cooling and along described desired trajectory, waste material removed.
More specifically, described cooling step carries out in cooling fluid.
More specifically, described cooling fluid is the water under room temperature state.
More specifically, the degree of depth of described desired trajectory on lens blank is described lens thickness 1/3 to 1/2.
More specifically, described outside line of cut is greater than the density in the less region of waste material compared with the density of multizone at waste material.
More specifically, during cutting, first along described inner line of cut, cut, and then cut along described outside line of cut.
Like this, because the desired trajectory along consisting of inner line of cut and outside line of cut cuts, in cutting process, eyeglass is discharged by outside line of cut because absorb the caused expansion of heat meeting; And because the degree of depth of described desired trajectory on lens blank is less than the thickness of described eyeglass, heat that eyeglass absorbs can be too not high yet, thereby significantly reduced the probability that eyeglass produces slight crack so that scraps; Because the lens blank to after cutting carries out coolingly immediately, not only can take away in time the heat that eyeglass absorbs, can also along described desired trajectory, waste material be broken and be removed at an easy rate.
Accompanying drawing explanation
Fig. 1 is that the master of desired trajectory on a preferred embodiment of the present invention lens blank looks schematic diagram.
The specific embodiment
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Please refer to Fig. 1, is a preferred embodiment of the present invention, and the laser cutting method of the present embodiment eyeglass comprises the step of lens blank being cut along desired trajectory, and after cutting completes, carries out immediately step cooling and that waste material is removed.
Described desired trajectory is included in and on lens blank, defines the inside line of cut 1 of eyeglass 3 and the outside line of cut 2 that at least one pair of waste material 4 that is positioned at eyeglass 3 peripheries done further differentiation.In the present embodiment, described inner line of cut 1 is for to be positioned at the closed curve on lens blank, and the quantity of outside line of cut 2 is four.One end of described four outside lines of cut 2 is connected with described inner line of cut 1 respectively, and the other end extends respectively the edge of described waste material 4.The degree of depth of described desired trajectory on lens blank is less than the thickness of described eyeglass, and in the present embodiment, the degree of depth of described desired trajectory on lens blank is described lens thickness 1/3 to 1/2.When outside line of cut 2 is set, can make described outside line of cut 2 at waste material, compared with the density of multizone, be greater than the density in the less region of waste material.
During cutting, first along described inner line of cut 1, cut, and then cut along described outside line of cut 2.Like this, because the desired trajectory along consisting of inner line of cut 1 and outside line of cut 2 cuts, in cutting process, eyeglass 3 is released by outside line of cut because absorb the caused expansion of heat meeting.And because waste material is not cut off, eyeglass 3 absorb heat can be too not high yet, thereby significantly reduced the probability that eyeglass produces slight crack so that scraps.
In the present embodiment, described cooling step carries out in cooling fluid, and described cooling fluid can be the water under room temperature state, also can be the cooling fluid of other types.Because the lens blank to after cutting carries out cooling immediately; not only can take away in time the heat that eyeglass absorbs; and; tension between eyeglass 3 and waste material 4 can become compression due to cooling effect; crystal grain between eyeglass 3 and waste material 4 shrinks and diminishes rapidly; and both edges are played to certain reinforcement protection effect; can along described desired trajectory, waste material be removed at an easy rate; and the removing of waste material 4 action can not damage eyeglass 3, thereby reduced the generation of the phenomenons such as slight crack.The removing of waste material can adopt the mode of removing of manually along described desired trajectory, waste material being broken.
After waste material is eliminated, simply polished in the edge of eyeglass 3, can obtain finished product.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
