Point 48, in the upper strata glass 24 of laminated glass 23.3 Laser Focusing points, and position respectively are produced i.e. on laser beam axis 45
In per layer of laminated glass.
By mobile slide block 28 on slide rail 33, between 30,32 position come adjust same optical axis focus lamp 39,41,
Relative position between 43, so as to change position and energy minute of three Laser Focusing points 46,47,48 in per layer of layer glass
Cloth.Start two-dimensional working platform 35, make laminated glass 23 produce relative motion with multifocal dot laser 46,47 and 48, in every layer of glass
The high-temperature area produced by Laser Focusing point in glass, with leaving for Laser Focusing point, can reduce rapidly, produce and exceed glass
The tension of the fracture threshold value of glass material, makes every layer of glass produce through micro-crack, and along the extension of Laser Focusing point moving direction,
Until separating；For the cementing layer of laminated glass, its material mostly is PVB Polymer materials, and fusing point and gasification point are relatively low, swashs
When light focus point acts on cementing layer, meeting aerogenesis glueing material, so that cementing layer gasification cutting is separated.Because the method is
It is disposable to produce at least one focus simultaneously in each layer of laminated glass, and make each focus respectively with per layer of laminated glass
Interact simultaneously, therefore overall through-wall crack 52 can be produced in laminated glass 23, and along laser scanning direction extension, so as to realize
The integral cutting of laminated glass is separated.
Focus lamp 8,39,41,43 is conventional focusing lens.Multi-focus lens set can also adopt alternate manner reality
It is existing, as long as laser beam can be made to produce multiple focuses.Realize that the device that focus lamp or focusing lens are moved up and down is also not necessarily limited to
Cited structure in examples detailed above.
Two kinds of cutting mode differences are to produce the multi-focus lens set composition structure of multiple Laser Focusing points and corresponding
Lens clamping device it is different, its laser-processing system, separating mechanism, working process parameter etc. are identical.
For the laminated glass (4 layers, 5 layers etc.) of more layers, band aperture or diameter in multi-focus lens set can be increased different
The quantity of focusing lens, so as to increase the focus quantity of generation, makes Laser Focusing point quantity be equal to or more than the laminated glass number of plies,
According to same principle, the cutting of more layers laminated glass is realized.
When one Laser Focusing point of glassy layer or/and gluing material layers is difficult to separate, can adopt two or two with
On Laser Focusing point act on above simultaneously.
