As one preferred embodiment, as shown in Figure 1, the included angle A formed between the wind direction of described second row air holes and horizontal direction can be 45 ~ 75 °; Also the included angle A namely formed between the wind direction of second row air holes 16 as shown in Figure 2 and vertical direction ' be 15 ~ 45 °.Further, as shown in Figure 3, the aperture of each described air holes 15 ~ 17 can be Ф 1.1 ~ 1.3mm, and the air-flow of its blowout of the aperture of this scope is comparatively suitable.
Please continue to refer to Fig. 1.One is respectively provided with for sealing the air knife cover plate 2 of air knife air intake vent at the air intake vent end of upper and lower air knife 1.Can adopt between air knife 1 with air knife cover plate 2 and such as be threaded, and seal between air knife 1 and air knife cover plate 2 by O RunddichtringO 12, to ensure the sealing of hot air duct chamber 13 in air knife.
Refer to Fig. 1.Upper and lower air knife 1 position in the vertical direction can regulate, and its adjustment is implemented by adjusting pole 3.Adjusting pole 3 is separately installed with, for regulating the distance between upper and lower air knife 1 and silicon chip 14 respectively at the sidepiece of upper and lower air knife 1.
Refer to the partial structurtes schematic diagram that Fig. 6 a and Fig. 6 b, Fig. 6 a is upper air knife adjusting pole, Fig. 6 b is the top view of Fig. 6 a.As shown in Fig. 6 a, Fig. 6 b, the connection bracket 6 that upper air knife 1 is equipped with by its adjusting pole 3 is fixed on etching device or wet-method etching equipment.Fixed block 7 is equipped with in the be in the wind both sides of cutter 1 of adjusting pole, and fixed block 7 coordinates an adjustable lifting screw 8 is housed, and upper air knife 1 forms threads turn with lifting screw 8 and coordinates.During adjustment, by rotating lifting screw 8, the upper air knife 1 coordinated with lifting screw 8 is regulated to move up and down on adjusting pole easily, thus the distance between adjustable upper air knife 1 and silicon chip 14 upper surface.
Refer to the partial structurtes schematic diagram that Fig. 7 a and Fig. 7 b, Fig. 7 a is lower air knife adjusting pole, Fig. 7 b is the top view of Fig. 7 a.As shown in Fig. 7 a, Fig. 7 b, the fixed block 9 that lower air knife 1 is equipped with by its adjusting pole 3 is too fixed on etching device or wet-method etching equipment.Adjusting pole is equipped with the adjustment block 10 of band vertical direction long slot bore (figure slightly) in the both sides of lower air knife 1, lower air knife 1 is by being movably arranged in the adjustment block 10 of adjusting pole with long slot bore clamping.Long slot bore is equipped with hold-down screw 11, by the adjustment high and low position of hold-down screw 11 in long slot bore, can regulate the distance between lower air knife 1 and silicon chip 14 lower surface coordinating with long slot bore and install easily.
As one preferred embodiment, the adjustable distance between described upper air knife 1 and silicon chip 14 is for being no more than 15mm; Adjustable distance between described lower air knife 1 and silicon chip 14 is for being no more than 10mm.Further, make the distance between upper and lower air knife 1 remain on 5 ~ 10mm scope by adjustment more suitable, can make to dry up effect and reach preferably state, both can ensure that silicon chip 14 is dried up in time, be unlikely to again to cause because blast is excessive silicon chip 14 to damage.
Refer to Fig. 1.In order to the silicon chip 14 by needing drying to process between upper and lower air knife 1, before and after lower air knife 1, both sides respectively can be provided with a roller 5.When silicon chip 14 is transmitted from etching device or wet-method etching equipment, can dock and move is carried on these two rollers 5, carries out drying to opposite side horizontal feed (as diagram horizontal direction arrow indication) between upper and lower air knife 1 by side.As one preferred embodiment, the arc transition that the profile of air knife 1 can have air channel 13 inner with it corresponding narrows shape.The circular arc portion of lower air knife 1 can make air knife penetrate with between two rollers 5 and not interfere, and can fit as far as possible with roller 5 simultaneously, forms approximate confined space, loses to reduce the process of drying up as far as possible at the hot blast of silicon chip 14 lower zone.
Consider that air knife is the design form of arc transition wide at the top and narrow at the bottom, its machining deformation is larger, therefore, the main material of air knife 1 can select POM (polyformaldehyde) forming materials to make, and it can meet good mechanical strength, rigidity (indeformable after processing) and the heat-resisting quantity (indeformable under high temperature) of air knife requirement simultaneously.
Device of the present utility model in use, by passing into gas in the air channel, inside 13 of air knife 1 arc transition wide at the top and narrow at the bottom up and down, the supercharging hot blast of acceleration is formed under the effect of vacuum compression pump, blow out respectively to vertical and reverse incline direction through the first ~ three vent 15 ~ 17, can by being carried on roller 5, by between upper and lower air knife 1 horizontally through silicon chip 14 on solution blow to rapidly silicon chip tail end, and can under hot-air seasoning effect, in time silicon chip 14 upper and lower surface is dried up, while reaching and drying up object, again can be easy to operate, quick.
In sum, the utility model is by three vents of wrong arrangement between the air outlet setting of upper and lower air knife, and a middle vent is obliquely installed towards silicon chip, when silicon chip roller drive under through air knife, from air knife exhaust vent blowout wind energy well the liquid of silicon chip surface is driven away fast; By arranging the air channel, inside of narrowing gradually in air knife, the process that wind is blown out from air knife air intake vent to air outlet, because air channel cross-sectional area reduces, wind speed increases gradually, and under the effect of vacuum compression pump, hot blast is formed, by silicon chip flash baking in the chamber of air channel; By arranging adjusting pole, the distance between upper and lower described air knife and silicon chip can be regulated respectively, both can ensure silicon wafer blow-drying, be unlikely to again because blast is excessive and cause silicon chip to damage.Therefore, the utility model has significant application advantage.
Above-describedly be only preferred embodiment of the present utility model; described embodiment is also not used to limit scope of patent protection of the present utility model; therefore the equivalent structure that every utilization description of the present utility model and accompanying drawing content are done changes, and in like manner all should be included in protection domain of the present utility model.
