Description
Technical field
The present invention relates to laser marking technical field, more particularly to a kind of effectively control laser glass mark is cracked
Method.
Background technology
The appearance of laser industry has promoted the development of opto-electronics, is the pillar industry of information industry.Ground according to prediction industry
Study carefully institute's measuring and calculating, domestic laser industry market scale is at 130,000,000,000 yuan or so within 2014.During to immediate objective in 2016, laser light production
The industry output value is estimated to surpass 400,000,000,000 yuan, and value added exceeds 100 billion.Laser industry garden it is built and under construction more than 16.I
Current laser enterprise of state has more than 3000.Laser industry is in rapid growth period.
Laser marking is one of most common laser processing technology, and its principle is the laser using high-energy-density to workpiece
Local irradiation is carried out, makes skin-material vaporization so as to leave the technologies of permanent marks, with the mark side such as traditional electrochemistry, machinery
Method, which is compared, has the advantages that high speed, flexibility is big, do not contact workpiece, and clear, lasting mark can be produced on various materials
Note.Generally, the material that can carry out laser marking is diversified, metal, plastics, ceramics, glass even organic material
Can be carried out laser marking, can mark depend primarily on the absorbing state of material on incident laser.In some glass flakes
On, it is identified on the surface of the optical filter chip of such as mobile phone or camera sometimes for them.Laser equipment is on glass
In general mark has three kinds of methods to can be used for crack-type and the quantity produced on control glass surface：First method is to adopt
Use multiple laser emission；Second method is using discrete point formation annular crack；The third method is to produce polygon surface
Crackle.A kind of clear-cut witness marking can be produced on glass using a laser emission, but crackle and stress pattern
Direction by the Directional Extension moved perpendicular to laser.After mark printing in the short time even after a few days, these are perpendicular to sharp
The crackle of light moving direction will form new crackle, the outer near zone formation fragment of former mark be expanded to, so as to influence mark
Definition.Using multiple laser emission, the region adjacent with marked region is set to be heated by heat transfer, so that these regions
Stress gradient is formed, the possibility of secondary rupture is reduced.The mark on soda-lime glass and borosilicate glass in this way
It is largely effective.Laser emission is to be melt into mark on silica glass and quartz glass more effective, because both materials
The coefficient of expansion is very low.Second method be using a series of annular cracks formation word, bar code, square or rectangular code and its
His shape code pattern.Glass produces low-density annular crack by heating and cooling down circulation.Expansion extruding is produced when glass is heated
Adjacent material, when temperature is increased to glass softening point temperature, the protrusion glass of glass rapid expanding one low density material of formation
The dome on glass surface.Because light spot energy is higher in the temperature at Gaussian Profile, therefore spot center.When this high-temperature region is returned to
During close to original position, the center of annular crack is formed in this region.Between low-density formation area and standard density area
Joint forms stable annular crack.This method is suitable in ordinary optical materials and tempered glass, chemically strengthening glass
Or mark in common sodium calcium float glass.The third method be also use same heating and cooling procedure, be all make it is a certain
The glass surface of designated volume changes.But the size of hot spot used in the third method is than larger, in two kinds of density areas
The boundary line of joint does not have annular crack method clearly demarcated like that.The mark that this method is produced not be immediately just energy it is observable,
It is required that just starting to produce trellis crackle along laser labelling region after being slightly pressurized.Filled out with produced without fragment polygon striped
Fill pattern formation word, figure and various codes.Because this method requires pure matter surface, with high-quality vehicle glass energy
Print and clearly mark.
Although the method for the reduction secondary rupture of glass in laser marking technology existing at present, it is of the prior art
Or method effect is poor, or cost is high, its popularization and application is limited.
