Abstract
An embodiment of the invention discloses a technology for laser internal-engraving of natural crystal jewels. The technology comprises steps as follows: firstly, the jewels requiring internal engraving are fixed on the working table top of equipment; according to the different jewel types, required laser devices are selected, then laser parameters including the wavelength, the power, the current, the frequency, the marking speed and the pulse length are adjusted, and the number of layers requiring laser internal-engraving is set; the laser focal length is adjusted to be in the middle of the thickness of the jewels, light enters from surfaces with the relatively small radian, and the front sides and the back sides of patterns are mirrored if the light enters from the back sides; and the laser energy is triggered, and internal engraving is performed. With the technology, the original structures of the jewels are kept most completely while the artistic value of the jewels is improved, the original quality of the jewels is not changed, and no substances which do not belong to the jewels originally are added to the jewels. Through internal engraving, the jewels are beautiful and elegant, the inexplicable mystery is realized, and current aesthetic requirements of people are further met. The processing time is greatly shorter than that of traditional engraving technologies. The manpower is saved, and the time is shortened.
Description
Technical field
The present invention relates to cameo cut field, more particularly to a kind of technique of body laser inner carving native crystal body gem.
Background technology
Technology for fast carving in existing gem, is all to pluck out figure at gem back and then tumble in metal back side again to cover defect.It is interior carving really back of the body carving that this technique is said.The time and efforts for needing consuming very big using this technology overleaf carves out the pattern of fineness, while have also been changed the quality of gem, reduces gem and removes original value after technique.
The content of the invention
Embodiment of the present invention technical problem to be solved is, there is provided a kind of finished product is more attractive in appearance, the technique of the value more body laser inner carving native crystal body gem that big, efficiency is significantly improved.
The technique of the body laser inner carving native crystal body gem, comprises the steps:
(1) gem carved in first needing is fixed on equipment work top;
(2) according to different gem types, then the laser instrument needed for selecting adjusts laser parameter:Wavelength, power, electric current, frequency, mark speed and pulse length, then the number of plies for needing interior carving laser is set;
(3) laser focal is adjusted to the centre of gemstone thicknesses, radian enters light compared with facet, if overleaf, figure before and after image;
(4) laser energy is triggered, carries out interior carving.
The laser instrument is green (light) laser, and the parameter of the green (light) laser is：The nm of optical wavelength 532, the W of power 5 ~ 20, the KHz of laser repetition rate 10 ~ 200, pump mode are end pumping, the type of cooling is air-cooled or water-cooled, working power 220v, mark speed 1-20000 mm/s, 30-40 μm of output facula diameter, anti-high reflectance zone isolator, the mj of maximum impulse energy 0.8, electric current regulation 9-45 A, pulse length 1-35 μm.
The laser instrument is ultraviolet laser, described when the parameter of green (light) laser is：The nm of optical wavelength 355, the W of power 2 ~ 20, the KHz of laser repetition rate 10 ~ 200, pump mode are end pumping, the type of cooling is air-cooled or water-cooled, working power 220v, mark speed 1-20000 mm/s, 30-40 μm of output facula diameter, anti-high reflectance zone isolator, the mj of maximum impulse energy 0.5, electric current regulation 9-45 A, pulse length 1-35 μm.
Implement the embodiment of the present invention, have the advantages that：
The technique of embodiment of the present invention body laser inner carving native crystal body gem, lifting the most complete structure for keeping gem script while gemstone art is worth, does not change the quality of gem script and does not add in gem and be not belonging to its material originally.Inside engraving is not only elegant in appearance, and allows people to have a kind of baffled air of mystery, more meets the esthetic requirement of present people.There is big shortening process time relative to traditional artistic carving.Manpower is not only saved, the time is more shortened.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below the present invention is described in further detail.
Embodiment 1
Carving in rosy quartz：Using green (light) laser, wavelength is 532nm, power 10W, electric current 25A, frequency 80KHz, mark speed 1000mm/s, 10 μm of pulse length.Radian enters light compared with facet, if overleaf, figure before and after image.Focus adjustment fixes gem to the centre of gemstone thicknesses, the use of the three-dimensional galvanometer figure number of plies is two-layer.Triggering laser energy, carries out interior carving.
Embodiment 2
Carving in green ghost stone：Using violet laser, wavelength is 355nm, power 5W, electric current 35A, frequency 50KHz, mark speed 800mm/s, 10 μm of pulse length.Radian enters light compared with facet, if overleaf, figure before and after image.Focus adjustment fixes gem to the centre of gemstone thicknesses, the use of the three-dimensional galvanometer figure number of plies is one layer.Triggering laser energy, carries out interior carving.
The technique of embodiment of the present invention body laser inner carving native crystal body gem, lifting the most complete structure for keeping gem script while gemstone art is worth, does not change the quality of gem script and does not add in gem and be not belonging to its material originally.Inside engraving is not only elegant in appearance, and allows people to have a kind of baffled air of mystery, more meets the esthetic requirement of present people.There is big shortening process time relative to traditional artistic carving.Manpower is not only saved, the time is more shortened.
Above disclosed is only a kind of preferred embodiment of the invention, can not limit the interest field of the present invention, therefore the equivalent variations made according to the claims in the present invention with this certainly, still belongs to the scope that the present invention is covered.
