Description
Technical field
The present invention relates to the resist technology field that ancient character is drawn, be specifically related to a kind of ancient character based on femtosecond laser technology and draw breakage-proof and repair system and method.
Background technology
Ancient character is drawn and for a long time be there will be unforeseen breaking-up in various degree.Current ancient character draws that to repair the industry talent rare, repairs and mainly comprises: solidifyingly to wash, take off mount, upper life paper and panchromatic, these links complement each other, and any one goes wrong, and all can have influence on the value of original works.The situation that tradition reparation is difficult to repair to the damage of the art work and naked eyes is general, therefore, needs more effectively more high-precision ancient character badly and draws restorative procedure.
Increasing material repairing manufacturing technology is that a kind of dusty material that uses successively piles up by selective laser sintering or fusing the increasing material manufacture method to manufacture a product.Relative traditional manufacturing technology, it can produce complexity, the highly difficult product that conventional art is difficult to produce like a cork.But, current increasing material manufacture surface often show intensity not high, blow the shortcomings such as powder and rough surface are high, need to carry out the process such as slagging-off.Only utilize vision monitoring to carry out controlling dimension in current increasing material mending course, do not have the real-time monitoring and control of microstructure and composition, we are unable to find out its microstructure, also just can not control better its mechanical performance.
In recent years, femtosecond laser (10
-15second) due to heat affecting little, machining accuracy is high, thus receives much concern in Precision Machining field.Femtosecond laser is within the duration of each laser pulse and matter interaction, avoid the existence of thermal diffusion, fundamentally eliminating the melting zone be similar in long pulse process, heat affected area, the impact that the multiple effect such as shock wave causes adjacent material and thermal damage, reduce greatly by the spatial dimension involved by process, thus improve order of accuarcy, its beam diameter can focus within 1 μm, and its precision can reach 100nm, the highlyest can reach 0.1nm.
Summary of the invention
Draw in renovation technique that the reparation precision existed is not high, process is loaded down with trivial details for ancient character and the defect such as easy breaking-up ancient character picture, the present invention proposes a kind of ancient character based on femtosecond laser technology and draw breakage-proof and repair system and method.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
One, breakage-proof and repair system drawn in the ancient character based on femtosecond laser technology, comprising:

If defect is depression (102), then will measure pigment (105) and be placed in glass substrate (106) lower surface being positioned at workbench (101) top, measure the pigment that pigment (105) is namely identical with depression (102) place color, can be obtained by real-time monitoring system.Glass substrate (106) lower surface is provided with some cells, measures pigment (105) and is placed in cell, the corresponding cell of this cell and depression to be filled.Control centre is according to defective locations data, rise the corresponding cell of control by the first axle to aim at depression to be filled (102), then rise control femto second optical fiber laser (107) probe cell corresponding to this by the second axle to aim at, femto second optical fiber laser (107) provides femtosecond laser to focus on this corresponding cell, because of the high-speed pneumatic ripple that vaporization phenomenon produces, get in Paint Drip (108) instillation depression (102), thus fill up depression (102).
In this concrete enforcement, glass substrate (106) lower surface is provided with 24 cells, and cell area is determined according to area to be repaired area, generally can be set to 10mm*10mm to 20mm*20mm; (103) distance 5mm ~ 50mm drawn in glass substrate (106) lower surface and ancient character, femto second optical fiber laser (107) probe and glass substrate (106) upper surface distance 5mm ~ 10mm.
If depression (102) is protruding (109), femto second optical fiber laser (107) is according to protruding (109) position data, there is provided femtosecond laser to focus on projection (109), thus remove protruding (109).By above-mentioned filling depression (102 and remove protruding (109), thus the high accuracy reparation realizing that ancient character draws.
Fig. 2 is breakage-proof method schematic diagram of the present invention, adopting fixture (206) that ancient character is drawn (203) is fixed on workbench (201), whether real-time monitoring system (205) scanning ancient character paint layer (204) exists cracking (202), if there is cracking (202), draw (203) cracking place to ancient character immediately to repair, restorative procedure is with the reparation of depression.
See Fig. 3, ancient character of the present invention is drawn reparation flow process and is specially:
(1) ancient character is drawn and is placed on workbench, adopts fixture to fix, and guarantees that surfacing drawn in ancient character.
(2) real-time monitoring system prescan ancient character paint layer is adopted.
(3) measure ancient character paint layer defects in conjunction with CCD camera and femto second optical fiber laser, described defect comprises depression, protruding and cracking.
(4) mensuration pigment is placed in glass substrate lower surface cell, cell and depression or ftracture is aimed at, femto second optical fiber laser probe is aimed at this cell.
(5) optical fiber femtosecond laser provides femtosecond laser to focus on cell, obtains Paint Drip and drops to depression or cracking place.
(6) optical fiber femtosecond laser provides femtosecond laser to focus on high spot, removes protruding.
(7) use real-time monitoring system to detect ancient character and draw whether reach required reparation precision, if reach, terminate; Otherwise, repeat step (1) ~ (6), until ancient character is drawn reach required reparation precision.
Meanwhile, real-time monitoring system can be drawn ancient character and monitors for a long time and detect analysis, and feeds back to control centre, if there is the above-mentioned reparation flow process of cracking OnNow.
