Description
Technical field
The utility model relates to a kind of being used for the solar battery sheet that chemical cleaning solar battery sheet surface later dries up is dried up air blade device; It is mainly used in the wet process equipment of battery sheet; Horizontal polycrystalline making herbs into wool cleaning machine for example; Horizontal is removed PSG etching cleaning machine, horizontal photoinduction plated film machine etc.
Background technology
When silicon chip or battery sheet in the horizontal wet process equipment through after the chemical cleaning, the sheet sub-surface can be residual quite a few liquid medicine and reactant, these materials must be disposed before slice, thin piece get into next process fully.The method that at present generally adopts air knife to cut water is in the industry handled.
At present, the air knife kind that can be used for the photovoltaic industry is extremely rare, and the air knife of most equipment manufacturer all is self-control.Air blade device is generally two kinds of basic structures such as common circular pipe type, reciprocally swinging formula at present.The air knife of common circular pipe type comprises two relative up and down pipes that feed Compressed Gas basically; Have a plurality of air knives hole on the every pipe, the axis in each air knife hole is to parallel and arrange along the axial direction of airduct, blows to cut that air-flow is inhomogeneous, air quantity is unstable; Be difficult to debugging and safeguard; And the life-span is shorter, and it is undesirable to dry up effect, also blows easily and splits silicon chip.And reciprocally swinging formula Air knife mechanism is complicated, and air consumption is huge, and silicon chip receives airflow influence in the process of walking easily, damages silicon chip, and maintenance cost and use cost are high.
The utility model content
The purpose of the utility model provides a kind of liquid medicine on the battery sheet that guarantees to dry up, and can not blow the solar battery sheet that splits the battery sheet again simultaneously and dry up air blade device.
The utility model solar battery sheet dries up air blade device, comprises two relative up and down air knives, and air knife comprises the airduct that feeds Compressed Gas, the air knife plate that links to each other with airduct; The air knife plate is provided with a plurality of air knife holes that communicate with airduct, and the axis in each air knife hole has the chamfering that tilts with the air knife axially bored line to parallel and arrange along the axial direction of airduct in the air knife plate both sides near air knife hole exits place.
The beneficial effect of the utility model: when Compressed Gas blows to from the battery sheet that passes through between two air knives up and down from the exit in air knife hole; Because the existence of above-mentioned chamfering; Near the air knife plate both sides air at air knife hole exits place under the drive of the Compressed Gas that comes out from the air knife hole, also stream (blowing) is to the battery sheet.That is to say; The chamfering of the air knife plate of the utility model has formed a kind of gas amplifier structure; Make the gas that blows to the battery sheet except the Compressed Gas that comes out from the air knife hole, also have air, so just can guarantee to dry up the liquid medicine on the cell silicon chip in the drive current downflow of Compressed Gas.Simultaneously, less at the pressure of the air of the drive current downflow of Compressed Gas, so can not being blown, the battery sheet do not split.
The above-mentioned air blade device that dries up, aperture, air knife hole is 0.22mm ± 0.03mm, the distance between the axis in adjacent two air knife holes is 2.5mm ± 0.5mm.Aperture, air knife hole distances too big or adjacent two air knife holes are too little, and gas flow is big, and the battery sheet may move (being blown displacement) under the blowing of gas.Aperture, air knife hole distances too little or adjacent two air knife holes are too big, and gas flow is little, and the battery sheet may not be dried up.
The above-mentioned air blade device that dries up, the air knife setting angle of the air knife axially bored line offset from perpendicular of top air knife is 15 °-17 °; The air knife setting angle of the air knife axially bored line offset from perpendicular of following air knife is 13 °-15 °; And the air knife setting angle of top air knife is bigger 1 °-2 ° than the air knife setting angle of following air knife.Because the less angle (13 °-17 °) of air knife axially bored line offset from perpendicular; Make a Compressed Gas part that blows out in the air knife hole blow to air knife plate one side; Another part blows to air knife plate opposite side, and like this, the Compressed Gas of air knife plate one side mainly plays the effect that dries up the battery sheet to the battery sheet; The Compressed Gas of opposite side mainly plays the effect of stable cell sheet, can dry up the battery sheet and can not make that again the battery sheet is blown displacement.Above the air knife setting angle of air knife bigger than following, guarantee that the drop on the battery sheet lower surface can not blown on the upper surface through the edge of battery sheet.
The above-mentioned air blade device that dries up, the distance that the air knife hole exits of the air knife hole exits place of top air knife and following air knife is in vertical direction is 10mm ± 2mm.Distance is too big, dries up weak effect; Distance is too little, and the battery sheet possibly blown and split.
The above-mentioned air blade device that dries up, the material of airduct, air knife plate is hard pvc.Adopt hard pvc both can obtain rational rigidity, effectively controlled cost again.
The above-mentioned air blade device that dries up, the compression pressure in the top air knife is 0.12-0.14MPa; Compression pressure in the following air knife is 0.1-0.12MPa; And the compression pressure in the top air knife is than the big 0.01-0.03MPa of the compression pressure in the following air knife.Above air knife in compression pressure bigger than following, guarantee that the battery sheet can not blown displacement, guarantees that simultaneously the drop on the battery sheet lower surface can not blown on the upper surface through the edge of battery sheet.
The above-mentioned air blade device that dries up, the chamfer dimesion in air knife plate one side is (1/3-2/3) H*45 °, H is the air knife plate lateral distance of air knife hole exits place to this chamfering place.Like this, the gas amplifier structure that the chamfering of air knife plate forms is better to the amplification effect of air-flow, more air is arranged under the drive of the Compressed Gas that comes out from the air knife hole in the air knife plate both sides near air knife hole exits place, blows to the battery sheet.
