In one embodiment, can perform to the goods (such as glass sheet 501) being in all dry state the method handling goods, as shown in Figure 5.Under the condition of all dry, glass sheet 501 can be placed in hole (void) or atmosphere, wherein, whole glass sheet 501 does not initially come in contact with fluid.Glass sheet 501 shown in Fig. 5 is in the state of all dry, and is placed in air.Also the method handling goods can be carried out to the glass sheet 501 being in fractional wettability state, as shown in Figure 9.Except the surface 503 of glass sheet 501 can be applied by a layer fluid 901, Fig. 9 and Fig. 5 is identical.But, as shown, be not that all surface of sheet 501 is all coated with stream layer.Such as, as shown, the opposition side of glass sheet can be xerantic greatly, although one or two first type surface of glass sheet and/or the part of edge surface can be dry, and the comparatively outer part of glass sheet is moistening.Like this, the glass sheet of fractional wettability does not immerse in water body, but is placed in hole or atmosphere, wherein glass sheet a part surface and fluid contact.In the exemplary embodiment shown in Fig. 9, the whole first type surface 503 of glass sheet 501 can by one deck fluid wets, and the opposite major surfaces of glass sheet 501 can be basic or all dry simultaneously, and wherein, glass sheet is placed in air.

Stream layer 901 can comprise water or other fluids arbitrarily, such as cleaning agent, solvent, rinse aid, drying aids or can with the fluid-phase in contactless operating control with or design other fluids mixed with them.Stream layer 901 also can promote the pre-wetted on the surface 503 of glass sheet 501, to avoid possible air pocket (airpocket), otherwise, may place with after limiting periphery chamber and center cavity on the surface of fluid distribution component relative to glass sheet, attempt setting up described air pocket when carrying out initial wetting to the surface of glass sheet.In one embodiment, the thickness " T " of stream layer 901 can be less than or equal to 8mm, such as, be less than or equal to 7mm, 6mm, 5mm, 4mm, 3mm, 2mm or 1mm.

In some embodiments, can start to make fluid be dispensing by periphery chamber with the step producing Bernoulli effect before, carry out the step with stream layer 901 coated article surface.Such as, can continue to carry out until major part (being such as placed in whole surperficial 503 of the glass sheet 501 in outside face 301 bottom trace of fluid distribution component 205) can be applied with stream layer 901 by the step that fluid 203 fills center cavity 507 shown in Fig. 6.

In other embodiments, can place with before limiting periphery chamber and center cavity on the surface making fluid distribution component 205 relative to goods, carry out the step on use stream layer 901 coated article surface, as shown in Figure 5.Such as, another coating unit (as fluid spray equipment) can be passed through and stream layer is provided.Or, one in the first fluid port 408 of fluid distribution component 250 and/or second fluid port 419 be used in place step before the surface of promotion stream layer coated article.Such as, as shown in Figure 10, second fluid port 419 can be used for the coating stream 1001 of distributing fluids, to provide stream layer 901.Once define stream layer, the fluid stream by second fluid port 419 can be closed, then can place fluid distribution component 205 relative to the surface of goods, to limit periphery chamber and center cavity, as shown in Figure 9.

Before fluid distribution component 205 being placed into the position as shown in Fig. 5 or Fig. 9, in process or afterwards, optionally lead quick-fried for initial fluid spray (burstoffluid) goods, to help fluid distribution component 205 relative to the proper orientation of goods.Such as, see Fig. 8, can distribute initial fluid quick-fried spray 801 from second fluid port 419, but as a supplement or substitute, from the quick-fried spray of first fluid port 408 distributing fluids, can tilt about direction of tilt 803 to help fluid distribution component 205.In one embodiment, as shown in Figure 2, articulated joint part 227 can be provided, thus contribute to about direction of tilt 803 run-off the straight.The quick-fried spray 801 of initial fluid can help outside face 301 orientation of fluid distribution component 205, to extend along the plane on the surface 503 being basically parallel to glass sheet 501.Like this, minimum clearance " G " can be increased by distributing minimum clearance around the periphery of outside face 301.Once achieve required towards, controller 221 can start blocking device (not shown) with articulated joint part 227 is locked to required towards.

Once placed fluid distribution component, such as, as shown in Fig. 5 and/or 9, described method can continue the step of filling center cavity 507, as shown in Figure 6.Before starting the step (see Fig. 7) of distributing fluids by periphery chamber, the step (see Fig. 6) of filling center cavity 507 can be started.Such as, the first and second flow control valves 211,215 are in original closed position, and controller 211 can initially pass through connection 4B transmission signal and open second brake control valve 215, thus start with fluid filling center cavity 507.If glass sheet 501 is placed in atmosphere with fractional wettability or all dry state, then can effectively from center cavity 507 transfer air with fluid filling center cavity 507, center cavity can substantially be filled by fluid or fill completely.In some embodiments, the step of filling center cavity 507 can be completed, before beginning distributing fluids is started by the step in periphery chamber, thus terminate the step of described filling center cavity 507.Or, can overlap be there is, thus even after center cavity 507 completely fills fluid and after distributing fluids is started by the step in periphery chamber, fluid continues flow through second fluid port 419.There is provided overlapping stream to assist in ensuring that not have air to leak and get back in center cavity.In other embodiments, flow through second fluid port 419 terminate and fluid begin to flow through first fluid port 408 start between can there is time delay (lapse).Such as, once fill center cavity 507, controller 221 can cut out second brake control valve 215, then wait for a period of time (such as 1-2 second), then first-class brake control valve 211 is opened, thus start to make fluid flow through first fluid port 408, with distributing fluids by periphery chamber.In some applications, overvoltage when may wish time delay to prevent two fluid streams from merging together, also can carry out timing to time delay simultaneously, gets back in center cavity 507 to minimize or to prevent air leakage.

Therefore, method as herein described can comprise the method such as handling goods (such as glass sheet) with fluid distribution component 205.Controller 221, by control signal being sent to drg 229 via connection 5, controls the movement of fluid distribution component, and fluid distribution component 205 can be moved to desired position by described drg 229.Fluid distribution component 205 initially can be moved to the desired location on the surface 503 relative to glass sheet 501 by drg 229.As shown in Fig. 5 and/or 9, once be in desired position, periphery chamber 505 can be limited between periphery surface 305a, 305b of fluid distribution component 205 and the surface 503 of glass sheet 501.In addition, center cavity 507 can be limited between the center surface 303 of fluid distribution component 205 and the surface 503 of glass sheet 501.As shown in Fig. 5 and/or 9, periphery chamber 505 is around center cavity 507.

As shown in Figure 6, described method also comprises with fluid filling center cavity 507, to remove the step of air from center cavity 507.Once remove air, as shown in Figure 7, then fluid can be dispensing by periphery chamber 505 to produce Bernoulli effect, goods are attracted to fluid distribution component 205 by described Bernoulli effect, maintain the minimum clearance " G " between the surface 503 of glass sheet 501 and the periphery surface of fluid distribution component simultaneously.

Owing to initially using fluid filling center cavity 507 by periphery chamber in distributing fluids before producing Bernoulli effect, can initially remove the air of significant quantity (such as, whole air), thus make center cavity substantially by fluid filling, such as fill completely.Once be filled with fluid, periphery chamber can be flowed through to produce Bernoulli effect by activating fluid, continuing described method.Removing air with fluid from center cavity can avoid the air leaked from center cavity to enter through the fluid stream in periphery chamber, otherwise, this may disturb Bernoulli effect, thus causes destruction Mechanical Contact possible between the surface 503 of uneven support and glass sheet and fluid distribution component 205.

Figure 11 provides the evidence of useful hoisting force, and this hoisting force realizes by adopting the fluid contactless operation device of Bernoulli effect, and the interference entering fluid stream from the air leakage of center cavity can not occur.Figure 11 shows fluid distribution component, and it immerses in water-bath completely, only has water not have air in center cavity, believes how the glass sheet this providing fractional wettability responds the evidence of the center cavity of fill fluid (and non-air).See Figure 11, the width of fluid port slit is 50.8 μm, and water velocity is 0.89 gallons per minute.The longitudinal axis or " Y " axle represent quality (unit, gram), and transverse axis or " X " axle represent minimum clearance (unit, millimeter).As shown, hoisting force is obvious, and has adhered to the minimum clearance distance of wide region.See Figure 11, for the flow velocity of 0.89 gallons per minute and the minimum flying height of 6mm, hoisting force can promote as many as 98 grams.

Also test as follows, adopt aqueous fluid distributed component to lift the glass sheet immersed completely in water-bath.For the water velocity of 1.2 gallons per minute, fluid distribution component can promote the sheet material of 125g, and minimum clearance is 7-8 millimeter, consistent and test of many times usually.
