Roller 1, upper piece platform 2, heating furnace 3 and bottom sheet platform 5 are the prior art.
In conjunction with shown in Fig. 2, Fig. 3 and Fig. 4, the tempering mechanism 4 include on one group of setting delivery roll 1 top air grid 6a and
Air grid 6b under one group of lower section, upper air grid 6a and lower air grid 6b are the prior art, they include one group of spaced wind
Plate 15 is equipped with two vents 16 on each aerofoil 15, and laser heating dress is respectively mounted between arbitrary two neighboring aerofoil 15
7 are set, the laser heating device 7 above and below delivery roll 1 is symmetrical arranged.
In conjunction with shown in Fig. 5 and Fig. 6, the laser heating device 7 includes fixed plate 8, and fixed plate 8 is rectangular slat shape knot
Structure, fixed plate 8 are fixedly connected in regulating device, are not drawn into regulating device figure, it includes the adjusting block for being connected and fixed plate 8,
The vertical screw hole of vertical direction setting and horizontally arranged horizontal screw hole are equipped on adjusting block, in vertical screw hole and level
Be connected a screw rod in screw hole, and can adjust laser heating device 7 by screw rod and adjusting block moves in vertical glass
Side-to-side vibrations on direction, and realize the adjusting of fixed plate 8 and glass spacing.One row's laser output head is installed in fixed plate 8
9, each laser output head 9 passes through 10 connecting laser 11 of optical fiber.The laser output head 9 of 1 top of delivery roll is sent out
The laser beam 13 gone out is perpendicular to the transport plane of delivery roll 1, the laser beam 13 that the laser output head 9 of the lower section of delivery roll 1 is sent out
It is obliquely installed upwards, and it is obliquely installed to 1 direction of transfer of delivery roll, the laser output head 9 of 1 the upper side and lower side of delivery roll is handed over
Mistake setting, laser output head 9 is to send out the mode locking Nd that the wavelength of laser beam 13 is 1.064 μm:YAG pulse lasers, solid
Also installation probe 12 on fixed board 8, pop one's head in 12 detection direction and 13 direction one of laser beam that corresponding laser output head 9 is sent out
It causes.
Laser output power density is adjusted, laser beam intensity is made to be more than 1GW/cm2, excite self-focusing；Adjust fixed plate 8
With the spacing of glass 14, the center in 13 self-focusing trace end heat effect area of laser beam is set to be overlapped with the center of glass 14, specifically
For：The center in laser beam heat effect area vertically downward 14 center of 2mm glass immediately below it, the laser beam heat tilted upward are made
With the center in area at 14 center of its oblique upper 2mm glass；It is preferred that pulsed laser energy output valve and pwm value, make laser beam energy
Value is more than glass melting threshold value in self-focusing area termination environment, while making heat effect area in laser beam axis to extending up to 1mm or more.
The principles of the present invention are：
Normal conditions, Nd:YAG laser can penetrate glass, and glass is only capable of absorbing small part laser energy, when laser beam intensity
When spending sufficiently large, due to nonlinear effect, laser also can largely be absorbed by transparent glass.Nd:YAG laser spatial distributions it is transversal
Face figure is gaussian-shape, a branch of Nd:When YAG laser transmits in vitreum, due to nonlinear effect, refractive index can be caused in beam
Center reaches maximum value, and decays outward, and this radial refractive index ladder acts as lens to laser beam, strong by focusing
Degree further increases, and lens effect is further amplified, and cause stronger focusing etc., finally, the terminal of self-focusing track goes out
The total absorption of existing laser beam；
The utility model is by the laser output head preferably with proper focal length, the laser for making laser output hair go out
Beam generates prefocus, then laser beam intensity is made to be more than 1GW/cm2, to excite self-focusing；
The vitreum in self-focused laser beam trace end region will absorb amount of heat, and vitreum conducts around, by
It is in high temperature relaxed state in vitreum, thermal coefficient is 2-4 times of room temperature glass, therefore heat effect area is larger；By adjusting
The spacing of laser heating tape and glass makes the center in self-focused laser beam heat effect area be overlapped with the center of glass plate；By excellent
The parameters such as pulsed laser energy output valve and pwm value are selected, so that heat effect area is reached grade, and make heat effect area in laser beam axis
Match to extending with the thickness of glass inner layer.
With the side-to-side vibrations of the movement and laser heating tape of glass, the laser beam being distributed in dot matrix forms transverse direction to glass
And longitudinal scanning makes adjacent scanning area is seamless to connect, glass inner layer is made to obtain uniformly adding by controlling laser heating tape amplitude
Heat.
By adjusting parameters such as laser intensities, glass inner layer is made to obtain enough heats, it is sufficient to offset quenching in glass
The rapid cooling of layer, to make internal layer be maintained at soft state, simultaneously as the heat that glass surface is directly generated with quenching air
A small amount of laser energy that amount exchange is transmitted much larger than the heat of inside glass and surface layer absorbs, the solidification therefore surface layer is cooled, at this point,
Surface layer establishes enough temperature gradients with internal layer, and after continuing cooling, glass will obtain enough tempering intensity.
