washing section

In one aspect, glass treatment equipment 10 comprises washing section 200, and this washing section 200 comprises washing shell 20 and the transfer path 100 therefrom passing through.When sheet glass 30 is advanced with delivery direction 102 along transfer path 100, sheet glass 30 is with substantially vertical direction orientation.

Washing section 200 comprises at least one first brush 210, and the setting adjacent with transfer path 100 of this brush is designed to contact with at least a portion of the first surface 32 of sheet glass 30, thereby wash, removes the chip on first surface 32.In addition, washing section 200 also comprises at least one second brush 220, and the setting adjacent with transfer path 100 of this brush, is designed to contact with at least a portion of second 34 of sheet glass 30.Washing section 200 is designed, described at least one first brush 210 and described at least one second brush 220 are oppositely arranged.More clearly say, the axle 222 of the axle 212 of the first brush 210 and the second brush 220 is positioned at the opposite side of transfer path 100.But, when there is no sheet glass between

brush

210 and 220, the diameter of these brushes extends each brush on transfer path 100, makes when there is sheet glass, each brush forms enough contacts area on sheet glass 30, thereby can remove unwanted particle from sheet glass 30.Washing section 200 can comprise

multipair brush

210 and 220, and these brushes are along transfer path setting, and each is in brush, and the axle 212 of brush 210 and the axle 222 of brush 220 are positioned at the opposite side of transfer path 100.In this way, can make to be applied to any normal force on the first surface 32 of sheet glass 30 by one first brush 210 and substantially equal to be applied to any normal force on second 34 of sheet glass 30 by one second brush 220, and opposite direction.

In order to help washing,

brush

210 and 220 can rotate.For example, but also unrestricted, the axle 212 of the first brush is basically parallel to sheet glass 30.Similarly, the axle 222 of the second brush is basically parallel to sheet glass 30.Motor 250 is connected with the axle 222 of the second brush with the axle 212 of the first brush by suitable transmission chain (do not show for the simple reasons, but those of ordinary skills easily understanding), thereby they are rotated together.Brush 210 and 220 sense of rotation can make sheet glass 30 along transfer path 100 by delivery direction 102 negative line feeds.As shown in Figure 4, for example, the first brush 210 turns clockwise, and the second brush 220 is rotated counterclockwise.In order to provide suitable stirring to remove chip, and allow driving roll 530 and 540 (as described below) to control sheet glass 30 along the transfer rate of transfer path 100, the speed of rotation of brush is about 200-1000 surface feet/minute (sfpm) (60-305 surface m/min), and for example 250,300,350,400,450,500,550,600,650,700,750,800,850,900 or 950sfpm (75,90,105,120,135,150,165,180,195,210,225,240,260,275,290 surface m/min).Although shown two pairs first brushes the 210 and second brush 220, can use the brush of any suitable number right.

Except end transfer roller 510, in order to promote the transmission of sheet glass 30, glass treatment equipment 10 also comprises a plurality of the first driving rolls 530, the setting adjacent with transfer path 100 of these rollers is also positioned at a side of transfer path, glass treatment equipment 10 also comprises a plurality of the second driving rolls 540, and the setting adjacent with transfer path 100 of these rollers is also positioned at the second side of transfer path.In one aspect, each roller in described a plurality of the first driving rolls 530 is basic relative with corresponding the second driving roll 540, and each roller in described a plurality of the second driving rolls 540 is basic relative with corresponding the first driving roll 530.In order to transmit sheet glass, each roller in a plurality of the first driving rolls 530 is designed, with a part for the first surface 32 of contact glass plate 30, and each roller in a plurality of the second driving rolls 540 is designed, with the part of second 34 of contact glass plate 30.

A plurality of the first driving rolls 530 are arranged on axostylus axostyle 534, thus supporting glass plate 30 in the vertical direction.On each axostylus axostyle 534, the quantity of the first driving roll 530 depends on the size of sheet glass, can correspondingly change.Similarly, a plurality of the second driving rolls 540 are arranged on each axostylus axostyle 544.A plurality of the first axostylus axostyles 534 and a plurality of the second axostylus axostyle 544 are pressed arranging along transfer path, and wherein, the first axostylus axostyle 534 is positioned at a side of transfer path 100, and the second axostylus axostyle 544 is positioned at the opposite side of transfer path 100.Motor 550 is connected with the second axostylus axostyle 544 with the first axostylus axostyle 534 by suitable transmission chain (do not show for the simple reasons, but those of ordinary skills easily understanding).As shown in Figure 4, motor 550 and transmission chain will make the first driving roll 530 by counterclockwise rotation, and the second driving roll 540 is rotated in the direction of the clock, cause sheet glass 30 to move by delivery direction 102 along transfer path 100.Although shown three pairs of the first axostylus axostyles 534 and the second axostylus axostyle 544, can use the axostylus axostyle pair of any suitable number.

In addition, the size of driving roll and material are designed, so that sufficient motivating force to be provided, react on the reactive force that brush 210 and 220 applies, sheet glass 30 is transmitted by washing section 200, sufficient supporting is provided, avoid sheet glass 30 to break, while reduces the contact area with sheet glass 30 as far as possible, avoids the defect of cut and so on.

Driving roll 530 comprises the thickness 536 of the part contacting with sheet glass on driving roll 530, and diameter 538.Referring to Figure 10, show diameter and the thickness of a driving roll 530.Each roller in

other driving rolls

530 and 540 has similar thickness and diameter.Thickness 536 is about 0.5-2 inch (about 1.27-5.08 centimetre).Along with thickness 536 increases, produces larger and contact area sheet glass 30, the risk increase that sheet glass is damaged.Equally, along with thickness 536 increases, be more difficult to the excentricity that produces in

balance axostylus axostyle

534 and 544, described excentricity is that the reactive force from driving

roll

530 and 540 promotes the result that sheet glass 30 makes it move along transfer path 100 with delivery direction 102.Along with axostylus axostyle excentricity increases, be more difficult between driving

roll

530 and 540 for sheet glass 30 keeps acceptable travel space.On the other hand, if thickness 536 is too little, make sheet glass 30 move through the size of motivating force of washing section 200 inadequate.Diameter 538 maximums of driving roll 530 are about 4 inches.Position to the diameter of the first driving roll 530 and the second driving roll 540 and

axostylus axostyle

534 and 544 is selected, and

roller

530 and 540 is separated mutually by gap 560, and described gap is less than the thickness 36 of the sheet glass 30 of transmission.Referring to Fig. 9 and 10.In other words, each is separated mutually by certain distance to the

axostylus axostyle

534 and 544 in axostylus axostyle, half of diameter that described distance is less than the first driving roll 530 adds half of diameter of the second driving roll 540, adds the summation of thickness 36 of the sheet glass 30 of transmission.Material to the first driving roll 530 and the second driving roll 540 is selected, and makes

driving roll

530 and 540 have compliance.In general, the compliance of a few tenths of a mm is acceptable.Therefore, when sheet glass 30 is transmitted by between driving

roll

530 and 540 gap 560 time, driving

roll

530 and 540 is compressed (due to their reason of compliance), to hold the thickness 36 of sheet glass 30.For example, the thickness 36 of sheet glass 30 can be equal to or less than approximately 1 millimeter, and for example approximately 0.8 millimeter, approximately 0.7 millimeter, approximately 0.6 millimeter, approximately 0.5 millimeter, or approximately 0.4 millimeter.

The material of driving roll also can affect the transmission of sheet glass.Described material can not pollute or scratching sheet glass, and described material and sheet glass 30 have acceptable frictional coefficient, thus avoid driving

roll

530 and 540 and sheet glass 30 between in sheet glass 30 transport process, skid.Consider above content, driving

roll

530 and 540 is 532 and 542 rubber that comprise polymerization at least externally, for example ethylene propylene diene monomer (EPDM) or Sheng Tepurui (Santoprene) rubber.Referring to Fig. 9.The hardness of the rubber of polymerization is about 30-60 Shore A, for example 35,40,45,50 or 55 Shore A.

As mentioned above, the first driving roll 530 and the second driving roll 540 arrange substantially relative to each other.A reason of this design is, balance normal force.In one aspect, each roller in a plurality of the first rollers 530 applies the first normal force to the first surface 32 of sheet glass 30, and each second roller 540 applies the second normal force to second 34 of sheet glass 30 accordingly.In one aspect of the method, the first normal force equals the second normal force substantially.Keep relative normal force substantially to equate significantly to have reduced to put on any vibration of sheet glass 30.

Washing section 200 also comprises a plurality of nozzles 230, nozzle 230 is arranged on to the both sides of transfer path 100.By nozzle 230 along delivery direction 102 be arranged on continuous every pair of driving

roll

530 and 540 and brush between 210 and 220.Nozzle 230 can to driving

roll

530 and 540,

brush

210 and 220 and sheet glass 30 spray any kind fluid to help washing process.Described fluid can be the cleaning fluid of any kind, for example liquid normally.
