With the raising for processing and requiring ability in flat-panel monitor manufacturing process, base plate glass is used as such as liquid crystal display
The demand of device (LCD) and Organic Light Emitting Diode (OLED) display etc is increasing, while to the overall matter of base plate glass
Amount requires also more and more higher.Generally, the base plate glass of better quality is obtained by overflow downdraw.Overflow downdraw, i.e.,
Fusion downdraw method, it is a kind of method that glass plate is produced in glass making techniques.Compared with other techniques, for example, float glass process and narrow
Drawing technique is stitched, overflow downdraw produces the glass plate with excellent flatness and smoothness surface, and without the use of secondary
Forming technology, that is, grind, polish etc..
Overflow downdraw is a kind of main mode of production of TFT planar substrates glass, and overflow downdraw can be produced
The good plate glass of surface quality.In production, overflow bottom method production planar substrates glass (band) can by transverse cutting unit,
Transverse cutting unit according to size requirement rule, cut, broken it is disconnected.Generally, base plate glass has certain geometry at transverse cutting unit
Curvature.Due to the presence of base plate glass surface geometry curvature, the chopping board strip and base plate glass, base plate glass and break bar of transverse cutting unit are equal
Can not effectively it be bonded.When transverse cutting unit break bar is rule, glass tape easily produces certain distortion.Divide in base plate glass from glass tape
From during, glass tape rocks substantially, easily influences the stress variation in glass tape, can be to shaping, annealing furnace inner pane of glass
Quality cause certain negative effect.
Therefore, it is necessary to which a kind of apparatus and method for manufacturing base plate glass, are especially cutting, breaking disconnected, separation process
In, increase the stability of glass tape, improve the mass property of base plate glass.
The content of the invention
In order to solve the problems of the prior art, the present invention proposes that one kind can reduce substrate in cutting substrate glass
Glass rocks, and lifts the stability of base plate glass, so as to lift the fixation liquid crystal substrate glass of the mass property of base plate glass

The base plate glass for having geometric buckling is moved to both sides, stretch and is opened up and make base plate glass surface that horizontality, substrate be presented
Under horizontality, the break bar and chopping board strip of transverse cutting unit can be bonded glass completely.Due to base plate glass surface geometry curvature
Reduce, when the break bar of transverse cutting unit carries out line cutting on base plate glass surface, base plate glass will not produce corresponding distortion, break
During disconnected separation, rocking for base plate glass is also obviously reduced.Inhibit the cutting of crosscutting place, break disconnected when, the distortion of base plate glass, shake
Dynamic phenomenon, and reduce the glass tape being passed up in the equipment of hot junction, while also have phase to the total quality characteristic of base plate glass
The lifting answered.
Further, by position-limit mechanism can be to sliding panel movement travel carry out it is spacing, base plate glass surface present
During horizontality, position-limit mechanism limits the further movement of sliding panel, and the fixation to base plate glass is more firm.
Further, sliding equipment is cylinder or motor, and driving is relatively reliable, makes the motion of sliding panel more stable, enters one
Step improves the stability of whole device.
Further, clamping device uses sucker or claw cylinder, and clamping or absorption that can be to base plate glass be more firm,
When applying outside side force to base plate glass, the slip of base plate glass is avoided, ensure that the reliability of whole device.
Further, sucker uses rubber suction cups, and base plate glass surface is made when quality of rubber materials avoids sorbing substrate glass
Into damage.
Further, the material for plate and two sliding panels being fixedly mounted is aluminium, good using the thermal diffusivity of aluminium, high excellent of intensity
Point, the heat resisting temperature of whole device is improved, and the rigidity of whole device is ensure that when applying side force to base plate glass,
Improve the steadiness of whole device.
The both ends of base plate glass flow direction are clamped or adsorbed using clamping device in the method for the present invention, simultaneously
Outside side force is applied to base plate glass both ends by mobile sliding panel, makes the surface energy of base plate glass with geometric buckling
Horizontality, the reduction of base plate glass surface geometry curvature is enough presented, the break bar of transverse cutting unit is rule on base plate glass surface
During cutting, base plate glass will not produce corresponding distortion, and when breaking disconnected separation, rocking for base plate glass is also obviously reduced.Suppress
At crosscutting place cutting, when breaking disconnected, the distortion of base plate glass, shaking phenomenon, and reduce the glass being passed up in the equipment of hot junction
Glass band, while also have corresponding lifting to the total quality characteristic of base plate glass.
