Description
Technical field
The present invention relates to a kind of marking process, relate in particular to a kind of technique that makes marks in ceramic material surfaces.
Background technology
The range of application of ceramic material is increasingly extensive, and it is not only as daily daily necessities, simultaneously at industrial circle also large-scale application gradually.
Cordierite is a kind of silicate mineral, and it can be colourless, but usually has light blue or lilac, glassy lustre.Cordierite also has characteristics, and they can send in different directions the light of different colours, and this is pleochroism.The cordierite of the excellent look of product U.S. is taken as jewel, and in addition, what industrial purposes cordierite does not have.Cordierite originates in schist, gneiss and the alteration igneous rock.Therefore people claim that also cordierite is two colored stones.Manually can synthesize magnesia cordierite, be used for refractory material.
Just owing to the outstanding high temperature resistant equistability energy of cordierite, cordierite is used as the ceramic carrier that high temperature catalyst is used, because need of production needs to stamp corresponding mark on each carrier, prior art gets on by dyestuff printings such as printing ink often.
But such dyestuff typography has many shortcomings:
1. its adhesive force is inadequate, fogs easily under the effects such as friction in the external world even comes off;
2. printing difficulty, when particularly running into the object surface of curved surface, printing is difficulty very;
3. the precision of printed patterns or literal is not high, when pattern or the literal of printing unintelligible when very little;
4. the dyestuff that gets on of printing is unstable, fades easily under high temperature or corrosive atmosphere, and therefore carrying out the object of mark can't hyperthermia drying or through the chemical treatment of fierceness.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of processing, reliable and stable technology for manufacturing marker on surface of ceramic material be convenient to.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of.A kind of technology for manufacturing marker on surface of ceramic material, it is characterized in that, the cordierite composition is greater than 90% in the described ceramic material, ceramic material surfaces is dry, uses laser beam to burn in ceramic material surfaces and carves, and described laser beam wavelength is 1.06 μ m, the light beam power output is 20w～50w, burning focuses on laser beam when carving, and the punctum that burns is 75%～120% of focal length apart from the focus lamp distance, and laser beam is 50～250mm/s in the sweep speed of ceramic surface.
Wherein, contain following composition in the described cordierite:
MgO：13.5±1.0wt％
Al
2O
3：35.4±1.5wt％

The specific embodiment
By describing technology contents of the present invention, structural feature in detail, realized purpose and effect, below in conjunction with embodiment and cooperate that accompanying drawing is detailed to give explanation.
See also Fig. 1 and Fig. 2, the various piece effect is as follows in the employed laser of the present embodiment equipment at bright quarter:
Red-light source 10: ruddiness power generation ruddiness;
Completely reflecting mirror 9: ruddiness is carried out total reflection;
Acousto-optic Q-switching 8: utilize the acoustooptic diffraction principle with continuous Nd: the YAG Laser Modulation becomes the pulse laser of high-peak power;
Form the Nd:YAG laserresonator by DPL semiconductor module 7, front and back diaphragm chamber mirror, the hydrous water cooling system, acting in conjunction produces laser;
Partially reflecting mirror 6: the laser that the YAG laser pump cavity is produced reflects;
Beam expanding lens 5: laser is expanded, in order to reduce the divergence of sending laser beam;
Probe 4: form probe by optical scan vibration lens system and focusing system; Comprise X-axis motor 2, y-axis motor 3, X-axis speculum 12, Y-axis speculum and field lens 1.
Field lens 1: laser beam focusing in working surface, and is obtained good focusing effect in the working region on the two-dimentional focal plane of vertical optical axis.
Beat the code process:
The object of being carved when burning enters operating position in the focus lamp (Range Focusing mirror 200mm), be that the laser beam of 1.06um is after beam expanding lens 5 expands by the laserresonator output wavelength, through eyeglass (being X-axis speculum 12 and the Y-axis speculum 13) reflection of X-axis, two galvanometer scanners of Y-axis, carved the working surface of object by optical focusing lens (being field lens 1) to burning again again.Galvanometer scanner produces under computer control fast and swings, and makes laser beam in plane X, the enterprising line scanning of Y two-dimensional direction, and sweep speed is that 50mm/s～250mm/s laser beam is gathered in one by one little bright depiction that forms of baking of carrier surface formation.
Many ceramic monoliths surface is very white, very bright, and the meeting reflector laser can not be beaten code.So need to select cordierite carrier.Because impacts such as the used raw material of carrier, processing technologys, beat code and will obtain better effect and will adjust various parameters, if the selections such as wave band, sweep speed, distance are incorrect, all will affect the effect of beating code, the handwriting is blurred for figure, and even not aobvious any vestige causes and plays the code failure.For example: when carving speed is transferred to 250mm/s when above, laser is few to cordierite carrier surface calcination time, and the handwriting is blurred for the figure of engraving; When carving speed is transferred to 20mm/s when following, laser is serious to cordierite carrier surface calcination, and engraving is dark, destroys carrier surface; When laser field lens and carrier distance is not focusing in the operating position (such as the position at 150mm or 240mm), the laser that shines carrier surface disperses, and laser intensity is very weak, can not engraving pattern; When the moisture that contains when carrier surface was many, the handwriting is blurred for the figure of engraving.
