Description
Technical field
The invention belongs to glass substrate manufacturing fields, and in particular to a kind of device and method for adjusting glass slab warping.
Background technique
Existing glass plate (thickness is between 0.3mm~1.4mm) refers mainly to the base plate glass for flat panel display,
It is one of critical component of flat-panel monitor.For many display equipments, the surfacing of glass used in panel
Degree must be within 150 microns, and any warpage fluctuation in glass can all adversely affect the quality of display, herein
Described warpage is the surface deformation of glass plate.
It is described such as in a lcd display including one layer of liquid crystal material being connected with glass substrate and transistor (TFT)
Transistor is arranged by the array of certain pattern, is orientated liquid crystal molecule by required form.
Therefore any variation of glass substrate wrapping can all lead to the variation of spacing between transistor and pixel, in this way can be straight
The defects of connecing the electric field and pixel for influencing display, keep the gray scale of display and color uneven, generating bright spot.Therefore in LCD
In the application of other glass displays, it is very useful for providing the glass substrate within the scope of acceptable warpage.
Generally under technological temperature stable case, it is to fail to stablize due to traction roller that the shape defects such as warpage, which occurs, in glass plate
Glass plate is clamped, so that glass plate is had phenomenon of running back and forth in downdraw process, glass pane surface shape is caused to change.Usually
The way for coping with this situation is the counterweight of increasing traction roller to increase chucking power, keeps glass plate stable.But the overweight meeting of counterweight
Cause glass plate is cracked to cause disconnected plate, influences to produce.
Summary of the invention
The present invention provides a kind of device and method for adjusting glass slab warping, makes glass to above-mentioned deficiency is aimed to overcome that
Glass plate is in the not increased situation of existing traction roller counterweight, and by enlarged surface coefficient of friction, Lai Jia great traction roller is to glass plate
Chucking power, run back and forth to effectively reduce glass plate, improve warpage grade.
In order to achieve the above object, a kind of device adjusting glass slab warping includes overflow down draw molding equipment, under overflow
Pulling shaping equipment rear end is provided with glass-cutting panel device, and overflow down draw molding equipment is provided with cutting glass plate equipment room and leads
Pick-up roll.
The arcuate friction device for increasing friction is provided on the traction roller.
The arcuate friction device includes front end arc-shaped device, and front end arc-shaped device is driven to move on traction roller
Rear end lead screw propulsion device.
Traction roller boss is provided on the traction roller.
The traction roller boss contact surface is hair side.
The width of the traction roller boss is less than the width of arcuate friction device on traction roller.
The overflow down draw molding equipment, traction roller and glass-cutting panel device are in same plane.
A kind of processing method for the device adjusting glass slab warping, comprising the following steps:
Step 1: glass metal flows into overflow down draw molding equipment, glass plate is formed；
Step 2: aid power of the adjustment traction roller to glass plate, so that glass plate be made to be pulled down by traction roller；
Step 3: the glass plate of stretching is cut into the glass plate of single sheet by mobile glass-cutting panel device.
In the step 2, by rear end lead screw propulsion device adjust between front end arc-shaped device and traction roller boss away from
From.
Compared with prior art, the present invention is to device by increasing traction roller to the aid power of glass plate, in overflow down draw
In method, traction roller chucking power is larger by the friction effects between boss surface and glass plate, therefore can be by increasing boss surface
Coefficient of friction increases frictional force, to increase the method for chucking power to keep glass plate stable, eliminates because glass plate carrys out fallback
Warpage caused by moving is bad.
Further, the present invention is provided with arcuate friction device, improves traction roller to the aid power of glass plate.
Further, the contact surface of traction roller boss of the present invention is hair side, increases skin-friction coefficient, to increase traction
Chucking power of the roller to glass plate.
Method of the invention can cause glass by adjusting the aid power of traction roller and glass plate when avoiding chucking power deficiency
Glass plate is run back and forth in molding equipment, so that the variation of the glass sheet shape in forming temperature section be caused to cause warpage bad
The problem of, reduced by the method for the frictional force of increase traction roller and glass plate because glass plate is run back and forth, to play tune
Rectify and improve the purpose of kind glass slab warping.

Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
Referring to Fig. 1 and Fig. 2, the present invention includes overflow down draw molding equipment 1, and 1 rear end of overflow down draw molding equipment is provided with
Glass-cutting panel device 6, is provided with traction roller 4 between overflow down draw molding equipment 1 and glass-cutting panel device 6, overflow down draw at
Type equipment 1, traction roller 4 and glass-cutting panel device 6 are provided with the arc for increasing friction on same plane, traction roller 4
Rubbing device 5, arcuate friction device 5 include front end arc-shaped device 7, and driving front end arc-shaped device 7 moves on traction roller 4
Rear end lead screw propulsion device 8, traction roller boss 3 is provided on traction roller 4,3 contact surface of traction roller boss is hair side, traction roller
The width of boss 3 is less than the width of arcuate friction device 5 on traction roller 4.
In the procedure for producing of overflow downdraw production plate glass, glass metal flows into overflow down draw molding equipment 1, is formed
Glass plate 2, glass plate 2 are pulled down by traction roller 4, are then moved glass-cutting panel device 6 for the glass plate 2 of stretching and are cut into single piece
The glass plate of shape.Arcuate friction device 5 is located at 1 rear end of overflow down draw molding equipment as can be seen from Figure 1, is placed on convex away from traction roller
3 level of platform is separated by a certain distance, the identical place of vertical height, can cause glass when traction roller 4 is to 2 chucking power deficiency of glass plate
Glass plate 2 is run back and forth in molding equipment, so that the variation of the glass sheet shape in forming temperature section be caused to lead to warpage not
It is good.It, can be by promoting rear end lead screw propulsion device 8 to make front end thus when warpage is bad caused by occurring to run back and forth because of glass plate
Arc-shaped device 7 is contacted with surface at traction roller boss 3, is surface roughened, and the friction system on surface at traction roller boss 3 is increased
Number, to increase traction roller boss 3 to the frictional force of glass plate 2, this has also just increase accordingly traction roller 4 to the folder of glass plate 2
Holding force, so that it is bad to mitigate warpage caused by even being eliminated glass plate running in overflow molding equipment back and forth.
The present invention during manufacturing glass plate by increase traction roller and glass plate frictional force method come reduce because
Glass plate is run back and forth, so that playing adjustment improves the method for glass slab warping.
