Abstract
The invention discloses a method of marking on a glass with YAG laser. The steps of the invention is that: first, a glass needed to be marked is chosen; second, a position needed to be marked on the glass by alignment is sprayed with black paint or black ink; third, lasers emitted by the YAG laser are used to mark on the position needed to be marked on the glass; fourth, the marked position is cleaned by means of cleaning fluid. The invention can increase the absorptivity of glass surfaces to near infrared laser and will greatly accelerate the application of the YAG laser on the glass industry.
Description
[technical field]
The present invention relates to the method for a kind of YAG laser at mark on glass.
[technical background]
Glass is very good to the absorption of CO2 laser (10.64 μ m), ultraviolet (355nm), deep ultraviolet (266nm) laser, relatively is fit to carry out glass processing.And YAG (1064nm) laser is not absorbed substantially, so, be difficult to adopt YAG laser directly to process.
The thermal conductivity of glass is very poor, during lasing, because of process zone is very little, can produce very high thermal stresses along processing route, makes material production crack or fragmentation.And the linear expansivity of glass is bigger, therefore easier fragmentation.So, adopt CO2 laser (10.64 μ m) that glass is processed, after destroying, skin glass can produce irregular crackle, make mark deleterious (irregular, surperficial burr etc.) as the edge, substantially can't satisfy the requirement of mark, at present, only the dot matrix effect can satisfy the mark requirement of some industries substantially.
Adopt the marking system of ultraviolet (355nm), deep ultraviolet (266nm) laser apparatus, very good to the processing effect of glass, but owing to exist speed slow at present, power is low, whole set equipment is on the high side, safeguards comparatively problems such as complexity, has limited and has used and promote.
[summary of the invention]
The technical problem that institute of the present invention desire solves provides a kind of specific absorption that can increase glass surface to near-infrared laser, is the YAG laser of 1064nm and adopt wavelength, will advance laser in the method for the YAG of the application of glass industry laser at mark on glass greatly.
The technical solution adopted in the present invention is: a kind of YAG laser may further comprise the steps in the method for mark on glass:
The first step, selection needs the glass of mark;
In second step, spray black paint or black oil at the position of mark that needs on glass;
In the 3rd step, the laser that utilizes the YAG laser apparatus to send carries out mark to the described position of mark that needs on glass;
In the 4th step, the mark position is cleaned with scavenging solution;
In the 5th step, mark is finished.
Described scavenging solution is alcohol, acetone.
Described YAG laser apparatus adopts semiconductor pumped or lamp pumping.
Described YAG laser apparatus has high-peak power.
The camera lens of described YAG laser apparatus adopts the condenser lens of f=100mm, f=80mm.
The technique effect that the present invention reached is: the present invention than equipment in the past mark on glass effective, mark speed is fast, no matter be to beat single-step effect, still the effect of single line filling is all got well a lot, and for example the single line edge is smooth, nothing collapses the limit, and the mark effect is attractive in appearance; Filling effect is smooth, exquisiteness.

[embodiment]
Present situation with prior art, be how to improve the specific absorption of glass surface at the bottleneck of the application of mark on glass with YAG laser, on the one hand, need to increase the single-point pulse energy of laser, as adopting the higher laser apparatus of peak power, as the laser marking machine (as the YAG-T50 or YAG-T80 two product of laser company of big nation) of lamp pumping series, adopt the less camera lens (as f=80mm, f=100mm condenser lens) of multiple; On the other hand, need handle, thereby reach the effect that increases specific absorption glass surface.
We at first experimentize with YAG-T50,
Method one: use black water mark pen to be coated in glass surface
Because the adhesive ability of water color ink is not too strong, after the laser radiation, coating is struck off, making a call in second time, glass has not just absorbed laser, but after wiping clean glass, can find indistinctly to have the marking of laser to stay glass surface, though unintelligible but reached the effect of mark, prove that this method is feasible, just need to improve homogeneity and sticking power.
Method two: use black belt to be attached to glass surface
After the mark, because the adhesive tape temperature distortion can not be close to glass surface, effect is undesirable.
Method three:
Use aluminium flake to be attached to glass surface, because aluminium flake is heated and evaporates, make glass surface be coated with the very thin zone of oxidation of one deck, this makes the extinction ability of glass surface strengthen greatly, finds in the test, after punching aluminium flake, laser can also be very strong, repeat mark 10 times after, the glass degree of depth has reached about 0.3mm, continue to beat dark again, the bottom surface has just occurred rough phenomenon.
Method four: use black oiliness mark pen
The black oil-based ink can spread upon glass surface better, and the mark effect is better, and mark is more clear, but the filling effect shading is not too even, adjusts tamped density and all can't reach poster edge preferably.
Method five: use black paint
Sample to the front is analyzed, reason is bad relevant with the pattern of lamp pump mark machine not too uniformly to cause shading, has adopted the optical mode better semiconductor pumped mark machine (DP-R50) that compares, and after surperficial spray black paints, the mark effect stability is even, reaches requirement substantially.
Concrete implementation step of the present invention may further comprise the steps as shown in Figure 1:
The first step, selection needs the glass 10 of mark;
In second step, spray black ink or black paint 13 or on the position of need mark, stick black belt or aluminium flake at the position that needs mark on the glass 10 with spray equipment 12;
In the 3rd step, mark is carried out at the position that has sprayed on the 14 pairs of glass 10 of laser that utilize the YAG laser apparatus to penetrate;
In the 4th step, the alcohol, the acetone and other organic solvent scavenging solution that spray with washing unit 16 clean the mark position;
In the 5th step, mark is finished, and the pattern 17 of its mark as shown in FIG. 1.
Other mark effects such as Fig. 2, Fig. 3, Fig. 4, shown in Figure 5.
