The specific embodiment
Now describe the present invention in detail with reference to as shown in the drawing several preferred embodiments.In the following description, many concrete details have been set forth, to provide to thorough understanding of the present invention.Yet those skilled in the art will be appreciated that the present invention's practice can not have some or all these concrete details yet.In other example, do not describe well-known feature and/or process steps in detail, purpose is unnecessarily not fuzzy the present invention.With reference to accompanying drawing and the following description feature and advantage that the present invention may be better understood.
Fig. 2 A illustrates a fluid bearing system 200, and it is supporting glass plate 202 in the edge of handling glass board 202, for example, and when cutting, polishing and/or polishing.Fluid bearings system 200 supporting glass plates 202 and the quality region of contact glass plate 202 (that is core) not.The fluid that is used for fluid bearings system 200 can be liquid or gas.When the fluid that is used for fluid bearings system 200 is a liquid, fluid bearings system 200 also makes and keeps glass board 202 to keep moistening, thus, has avoided because gathering at glass board 202 lip-deep particles of causing of static charge.Fluid bearings system 200 comprises a pair of fluid bearings 204 of arranging with the relation of subtend.Fluid bearings 204 is spaced apart and form a passage 206 of admitting glass board 202.One group of edge grippers 208 is clamped glass board 202 edges, and prevents that glass board 202 from skidding off outside the passage 206.Preferably, edge grippers 208 quality region of contact glass plate 202 not.
Fig. 2 B is the detail drawing of single fluid bearings 204.Fluid bearings 204 comprises stacked inflatable chamber (plenum) 210.The combined altitudes of this stacked inflatable chamber 210 (H) and width (W) can identical with width with the height of glass board 202 (among Fig. 2 A).Distance between the inflatable chamber 210 (S) can be the same or different.In some cases, can there be spacing (S) between some or all inflatable chamber 210.Perhaps, stacked inflatable chamber 210 can replace with single inflatable chamber.Each inflatable chamber 210 comprises that a flow plate 212 and is connected to the back plate 216 of flow plate 212 by inlet device 215.Back plate 216 is installed on the bearer frame 218.Bearer frame 218 can be coupled on aligning or the registration device (not shown), and this will allow fluid bearings 208 to adjust with respect to the fluid bearings or the glass board of a subtend subsequently.For example, back plate 216 also can be coupled to bearer frame 218 adjustablely, so that the spacing scalable between the inflatable chamber 210.Can there be tapering at the edge of flow plate 212 or expands outwardly so that glass board 202 inserts in the passage (206 among Fig. 2 A).
Fig. 3 A illustrates observed pressue-graph from the non-interaction water jet that traverses a plenum surface.This pressue-graph shows that non-interaction fluid jet produces local pressure on glass pane surface.When glass board was placed on the so non-synergistic plenum surface, a moisture film was formed between glass and the inflatable chamber.Yet the fluid pressure in the moisture film plane is heterogeneous.Fluid bearings is very responsive for the little disturbance in the jet (such as because the disturbance that hole size variation produced that machining tolerance causes).The heterogeneity that fluid flows and the small alignment of opposed jet will definitely not form glass vibration, and the utmost point does not wish to take place this vibration in the edge course of processing.Fig. 3 B illustrates observed pressue-graph from the interaction water jet.As shown in the figure, the pressure curve of interaction water jet does not show at the observed local pressure of non-interaction water jet.
In general, when flow plate 212 was made of porous materials, the plenum design that obtains uniform fluid pressure on the vertical bearing surface was just much simple.Aerated materials forms resistance to the caused perpendicular flow of gravity, thus, allows uniform fluid to be dispersed on plenum surface and the thickness.The flow plate 212 made by the aerated materials that manifests above-mentioned characteristic is first-selected, that is, the bore dia on the load-bearing surface 211 is 1/2 bigger than distance between the adjacent bores.Because fluid self can be on load-bearing surface 211 is distributed equably again, so, use the aerated materials of thick (for example, greater than about 1/8 inch (3.175mm)) can simplify the design of inflatable chamber.The example of aerated materials includes but is not limited to super high molecular weight (UHMW) high density polyethylene (HDPE) (HDPE), and for example it can be buied from the GenPore that is seated Pennsylvanian thunder fourth (Reading).Have found that following aerated materials is useful: the average cell size that aerated materials has in the scope, preferably between 10 μ m to 100 μ m, is preferably between 50 μ m to the 80 μ m between 5 μ m to 150 μ m.But the hole in the aerated materials can rectangular distribution also non-uniform Distribution, and can have the size of variation.The thickness of aerated materials in 10mm to 50mm scope, preferably is about 25mm usually.Fluid-pressure drop by flow plate thickness preferably is not more than 50%.
Fig. 3 B illustrates the average pressuure that synergistic water jet produces, and it is the function of passage (206 among Fig. 2 A) size.As shown in the figure, the average pressuure of synergistic water jet generation reduces with the channel size increase.The average pressuure that synergistic water jet produces also is subjected to the influence of jet speed, and jet speed is produced the hole dimension of jet and is fed to the influence of the water flow velocity in the hole that produces jet.Usually, can select channel sized and jet speed to reach desired average velociity on the glass pane surface.Preferably, being applied to pressure on the glass pane surface by jet provides enough rigidity to come glass board in the support channels, so that the glass board load-bearing surface of contact flow plate not.In some cases, can apply different amount of pressure to the different piece of glass.This can be by with the realization of getting off: make flow plate have different porosity parts, and realize traversing the desired pressure of glass counterpart in each part customization porosity; Perhaps in giving certain portions, change current.
Fig. 4 illustrates the device 400 of a processing glass sheets.The embodiment that can adopt one or more devices 400 or its to substitute realizes one effectively and the machining line of cost economy.This device 400 comprises a platform 404, and it preferably is rigidity and can be equipped with damping of vibrations mechanism.One anchor fitting 406 is installed on the end of platform 404.(or location) device 408 is aimed in these anchor fitting 406 supportings first.One bearer frame 410 is installed on the other end of platform 404 and is relative with anchor fitting 406.Bearer frame 410 comprises that cramp bar 412, one second alignings (or location) device 414 is attached on this cramp bar 412.First and second alignment devices 408,414 are spaced apart from each other and keep the relation of subtend.Fluid bearings system 200 is arranged between first and second alignment devices 408,414 and with it and is connected.Fluid bearings system 200 is supporting glass plate 202 in the course of processing, simultaneously, keeps the quality region of glass board 202 to be in brand-new harmless state.
Can operate first and second alignment devices 408,414, adjust fluid bearings system 200 or adjust the position of its parts as required with respect to platform 404 or glass board 202 or processing equipment 500.First and second alignment devices 408,414 can be translational worktables, the parts of its energy one or more dimensions ground translate fluid bearing system 200.For example, first and second alignment devices 408,414 can be the x-y bench board, for example, can use such as DC or stepping motor or the such motor of servomotor and come manually or automatically to drive them.The x-y bench board can be compound table or can be made up of indivedual translational worktables.Also can provide the bench board or the actuator of the translation that is less than two dimension to be used as alignment device 408,414.For example, only just enough along all parts of y axial adjustment fluid bearings system 200.Alignment device 408,414 also can comprise sloping platform so that allow convection cell bearing system 200 to make angular adjustment.
When using one to have the edge of processing equipment cutting glass plate of case, the glass sheet quality zone is protected to avoid running into generated contaminant in the course of processing.Glass plate edge can be with processing such as a grinding wheel and a stroke instrument of carving taking turns.Also can use other processing unit (plant) such as slurry jet or nitrogen jet to replace grinding wheel.Can use the case that has slurry jet or nitrogen jet current device to surround the edge of glass board.In the course of processing, case allows to use chemical coolant or other lubricant.Cooling system conditioner is contained in the case, thus, avoids staining the quality region of glass.The cooling system conditioner of use such as silane base class can improve machining tool, and (for example, grinding wheel) efficient also can help to restore the cracking in the glass edge, forms more solid edge.Processing after edge chips can current clean in the case with being contained in.
Fig. 6 B illustrates another modified version of Fig. 6 A structure.In this example, the edge grippers 208 at clamping glass board 202 edges is coupled to an end effector (effector) 602, and this operating control is coupled to a translation or registration device 604, for example a linear slide again.In this figure, also with dashed lines 600 expressions of fluid bearings system 200 are can see glass board 202 and edge grippers 208.In the course of processing, processing equipment 500 remains on the top and bottom of glass board 202 still, operates linear slide 604 simultaneously so that glass board 202 moves with respect to processing equipment 500.Glass board 202 is transported to fluid bearings system 200 on first bottom conveyor 606, and is used to have on second bottom conveyor 608 of another station of similar or same structure one and leaves fluid bearings system 200.Glass board 202 can rotate 90 degree before arriving next station.Because glass board 202 keeps moving, so this example has higher output.
Above-mentioned various structure also can be configured to horizontal orientation rather than vertical orientation as shown in the figure.In a horizontal structure, fluid bearings will be a level.Such as any accessory equipments that is used to handle glass board such as bottom or built on stilts forwarder, edge grippers, robot suction cup, preferably in non-quality region, normally touch glass board from the place of glass plate edge 5-10mm.Use said structure, if the fluid in the fluid bearings is a liquid, so, it is moistening that glass board keeps in fluid bearings in the edge course of processing, and this can prevent because the particle on glass board that static charge causes gathers.Glass board keeps the moistening fluid stains that also prevents on glass board.
Following course of processing example is not thought and is limited other description of the present invention only for illustrative purposes.
Example 1
One continuous glass board is formed by fusion process.When continuous glass board occurs from the withdrawing device, use a portable anvil method (TAM) from continuous glass board, to cut the glass board that requires size down.TAM comprises that using stroke to carve assembly comes continuous glass board is drawn quarter, carves assembly for described stroke and moves with the speed of mating continuous glass board speed along continuous glass board.In standard TAM cutting, drawing engraving device is that machinery is drawn the wheel at quarter.Just before continuous glass board being drawn quarter, a manipulator is applied to suction hood on the continuous glass board.The end effector that is connected to the manipulator of suction hood also moves with mobile glass board.In case draw the carved glass plate with TAM, this glass board of robot bends is to separate it with continuous glass board.Then, manipulator is transported to glass board on the one built on stilts forwarder, and this forwarder moves on to another station with glass board.In this example, when continuous glass board during by the withdrawing device, one group of roller (or edge guiding device) is clamped the edge of continuous glass board, as well known in the art.In this case, next station is a station of removing vertical bead (VBS), that is, the vertical edge of finishing glass plate is also removed the station of bead.Normally, before the glass board cooling, remove bead, otherwise too many stress can be stayed in the glass board.If the edge of glass board does not then need VBS not by the roller in the withdrawing device (or edge guiding device) continuously.
Example 2
Handle on a machining line as the glass board of in example 1, preparing.This operating line comprises one or more fluid bearings of the present invention system.The course of processing comprises uses the thermal shock cutting technique that glass board is cut into a certain size.This thermal shock cutting technique process prescription is in United States Patent(USP) Nos. 6713720,6204472,6327875,6407360,6420678,6541730 and 6112967, and this paper quotes their institute's contents of instructing for your guidance.Usually, thermal shock cutting technique process comprise use one such as the such heating source of laser or plasmatorch along a fine rule heating glass plate.Behind the fine rule heating glass plate immediately along fine rule quick cooling glass board.Heating and cooling circulate near the interior thermal shock that forms of glass board the fine rule, and this causes along the cracking of fine rule propagation.Glass board is separated, or can easily separate with glass board along the crack.
In thermal shock cutting technique process, glass board can be bearing on the air bearing.Air bearing can be simple, for example, has the hole of the advertising air glass board that suspends, or such as
Air/the vacuum combination of air bearing, it can be buied from the New WayAir Bearings that is seated Pennsylvanian Aston (Aston), perhaps can be Core Flow air bearings.Perhaps, above-mentioned fluid bearings system can be used in the air as fluid.After glass board is cut into a certain size, the edge of processing glass sheets, simultaneously, supporting glass plate in the fluid bearings system.Can side by side process first group of subtend edge of (cutting and ground/polished) glass board.Then, also rotatable glass board or do not rotate glass board ground remaining subtend edge group of processing glass sheets side by side.Because TAM and VBS in the example 1 are unclean, so, glass board will be cleaned subsequently.Clean after the glass board, use air knife to come the dry glass plate.Check glass board then.After the inspection, glass board can be coated with and apply protective coat.Pack glass board then in order to transportation and/or storage.
Example 3
In supporting glass plate in the fluid bearings system, and use the processing equipment have case that glass board is cut into a certain size, glass board is as processing in the example 2.
Example 4
Except TAM cutting and VBS pass through the thermal shock process, glass board is as preparing in the example 1.Thermal shock process cleans, and does not produce the glass chip that meeting pollutes the glass sheet quality zone.Then, except because TAM cutting and VBS are clean and do not need to clean at last the glass board, as example 2 or example 3, glass board is processed.
The present invention typically provides following advantage.Can avoid usually abundant cleaning and the drying to glass board relevant with the machining process of prior art, for example, as described in the above example 4, TAM cuts and VBS cleans.Above-mentioned machining process can easily be integrated with melting process.In the edge course of processing, the fluid bearings system provides the supporting to glass board, and the quality region of contact glass plate not.The fluid bearings system increases the hardness of glass, can more accurately cut and prevent distortion in the glass plate edge course of processing.The fluid bearings system can be used to control the temperature of glass board so that edge treated efficient reaches maximum.The machining line floor area of vertical orientation reduces widely than the manufacturing line of horizontal orientation.In the edge treated process, cover the edge of glass board by case, can make glass board be in the intrasystem pollution of avoiding the glass sheet quality zone simultaneously of fluid bearings.
Although the embodiment with reference to limited amount has described the present invention, have benefited from those skilled in the art of the present invention and will recognize that, can design other embodiment and the scope of the present invention that do not break away from here to be disclosed.Therefore, scope of the present invention should only be limited by appended claims.
