Description
Technical field:
The present invention relates to use in a kind of TFT-LCD base plate glass moulding process vertically to towing mechanism.Be specially adapted to overflow downdraw produce 4.5 generation base plate glass.
Background technology:
Be used for the TFT-LCD base plate glass and have high heat resistance, high-clarity, agent of low hygroscopicity, high flat degree, good anti-solvent, scratch resistance, anti-strong acid, characteristics such as anti-highly basic.Thickness of glass has good geometrical property and outstanding optical index between 0.5mm-1.4mm.Particularly liquid crystal flat panel display is strict to the specification of quality of glass baseplate surface planeness and thickness.If the substrate precision can not guarantee that the spacing that then constitutes between the two substrates will produce local error, can directly have influence on like this indicating meter electric field distribution one to property and pixel resolving power, make the gray scale of indicating meter and color inhomogeneous, produce defectives such as spot.Also should reach 1/10mm for base plate glass geometrical dimension claimed accuracy.
At present, produce in several kinds of maturation process of liquid crystal substrate glass, the most popular with the overflow method of forming.Because the base plate glass surface grinding of operation afterwards of adopting the overflow method of forming to produce.But this technology is very high to the control requirement of production process, and flow, temperature, tractor pulling force require to accomplish synchronously and accurate control that changing slightly all to cause drawing the excessive sheet glass of breaking of pulling force of tractor.And the disconnected plate of sheet glass has reduced production efficiency and production good article rate in case generation often needs the adjustment operation that carry out complicacy again to the correlation parameter of traction for a long time.So; During LCD sheet glass is produced; Except the bending strength that improves glass; Also need the take off roll of tractor accurately be designed, lead strict process condition in the dark process to guarantee continuously, to guarantee in the normal productive process physics, the optical index of TFT-LCD base plate glass substrate to guarantee base plate glass.
Summary of the invention
The objective of the invention is to be adapted to the actual needs of liquid crystal substrate glass 4.5 generation product, to press over system production in the improvement carried out of traction stretched device.Make renewal for key part in the specific equipment of large scale liquid crystal base plate glass-4.5 generation product and change design.Particularly the improvement of key part take off roll designs and new plan is made in the meticulous adjusting of take off roll distance and pressure, to guarantee the quality percentage of liquid crystal substrate glass 4.5 generation product.
The concrete improvement that the present invention made be to the overflow method of forming produce use in the TFT-LCD base plate glass vertically to towing mechanism.Comprise two take off roll of supporting even part each other in the structure after the improvement, two take off roll that synchronous backward rotates and the frit that is between two rollers are formed the friction transmission pair.Key is at place, columned take off roll two ends two boss to be set; Distance (L) between two boss is not less than 866mm; The width of each boss upper surface (L1) is 40-48mm; Each boss upper surface and take off roll cylindrical surface vertical range (H) 0.5-1.5mm, the total length of take off roll is not less than 1225mm.；
Will break the limit after liquid crystal substrate glass is produced off with the fingers and thumb handles; What 30mm was reserved on the woollen every limit of glass after the moulding breaks the hem width degree off with the fingers and thumb; Take off roll will rotate continuously in liquid crystal substrate glass production, could firmly grab sheet glass like this, and each organizes roller turn will inevitably produce error on track.The traction track of many group take off roll can not be in a straight line.So, must consider the reservation amount of error.Two boss distances on the take off roll of comprehensive various factors consideration contact glass charge level should guarantee 866mm.
Should there be length in reserve at the take off roll two ends, to guarantee the processing structure that is connected with transmission rig with positioning element, consider the insulation of hitch structure boss simultaneously, above length in reserve should, 966+ (25+104.5) * 2=1225mm.Think that finally the effective dimensions of roller is 1225mm.

Embodiment
The new design of the take off roll structure that provides according to the present invention, improved towing mechanism can satisfy production requirement fully, guarantees 4.5 generation TFT-LCD base plate glass moulding process quality.
The overflow method of forming is produced in the TFT-LCD base plate glass employed vertically to towing mechanism, comprises two take off roll 1 of supporting even part each other in the structure, and two take off roll that synchronous backward rotates and the frit 2 that is between two rollers are formed the friction transmission pair.Key is that take off roll are cylindric; Take off roll are provided with two boss 3 at the place, two ends; Distance L between two boss is not less than 866mm; The width L1 of each boss 3 upper surface is 40-48mm, and each boss 3 upper surface and take off roll cylindrical surface vertical range H are 0.5-1.5mm, and the total length of take off roll is not less than 1225mm.
Take off roll 1 are provided with excessive fillet R between set boss 3 end faces of end positions and take off roll cylindrical surface.
Take off roll distance L 2 between the set boss 3 of end positions is apart from the end face of take off roll is not less than 125mm, the rotational support that accessory processing goes out on the take off roll in above distance with drive syndeton.
More than the take off roll that rotate of said two synchronous backwards at least one be set in and can be used on the work top 4 of horizontal shift adjustment, make that pressure and the force-to-stretch to the glass charge level matches in the corresponding boss 3 upper surface parallel distances of two traction rods and the processing requirement that is designed.More than can guarantee has enough big tractive force and don't breaks as for frit 2 is produced frit 2.
The take off roll axis that two synchronous backwards more than saying rotate can be used for the take off roll device integral body of horizontal shift adjustment position to be positioned at and to have on the work top perpendicular to take off roll axis direction horizontal translation degree of freedom in same horizontal plane.
Further improvement can be used two take off roll that diameter is different, but will guarantee that the LV direction of two boss point of contact, size are identical.That is to say: the synchronous backward in the traction rollers of two synchronous backward rotations is to guarantee that corresponding boss surface has the LV of identical size.
The Technological improvement plan that the teachings that above design philosophy provides can realize is; The take off roll of horizontal shift adjustable position can substitute with two crowd wheel C that meet the synchronous backward condition.
