Embodiment
For above-mentioned purpose of the present invention, feature and advantage are become apparent more, below in conjunction with the drawings and specific embodiments the present invention is described in further detail.Need to prove, each structure in the accompanying drawing is schematic rather than determinate, so that those of ordinary skills understand principle of the present invention best, it is not necessarily drawn in proportion.
Fig. 1 and Fig. 2 show the existing mesh belt blow-drying device that adopts for the spraying equipment of solar cell preparation, and wherein said spraying equipment can be PV360 spraying equipment for example.As shown in Figure 1, guipure 3 can be mobile under the effect of two secondary rotation roller bearings 1 and 2, and silicon chip will be placed on the guipure that is horizontal, and advance with guipure.Described mesh belt blow-drying device is positioned at guipure below, its substantially by cylinder 5, gantry 4, blow-out nozzle 6, nozzle mobile device 7, fixedly gantry and nozzle mobile device support 8, gas-tpe fitting 9, provide jet tracheae 10, inductor 11, the parts such as 12 to consist of.When spraying equipment energising normal operation, provide the compressed-air actuated electromagnetically operated valve of nozzle often to open, compressed air is communicated with nozzle by the tracheae that is connected with nozzle, uninterruptedly provides gas, so that nozzle can be blown continuously.The inductor at cylinder two ends provides signal, comes Control Nozzle to move back and forth at the Width of guipure by nozzle mobile device, aims at simultaneously guipure and blows, and finishes the task of drying up guipure so that the cylinder of nozzle is housed.
Herein described guipure Width refer to the guipure plane on the perpendicular direction of its moving direction.The moving direction of guipure illustrates with arrow in Fig. 1.The structure of single nozzle has the very low efficient that dries up, and usually can cause drying up inhomogeneous or dry up incomplete.In the situation that nozzle can't dry up guipure fully, the acid solution on the guipure is drippage constantly, especially when guipure move to cylinder directly over the time.Long-term work is under this acid environment, and all parts of cylinder all can be damaged.For example the sealing ring of cylinder can be by acid liquid corrosion, thereby causes cylinder leakage tester and can't work.In addition, the nozzle near guipure also is easy to be corroded.As can see from Figure 2, a part of tracheae is coated by gantry 4, and gantry 4 need be followed nozzle mobile device and moved around, and the tracheae that therefore is positioned at is wherein standing to be very easy to fracture in this reciprocating situation for a long time.
Fig. 3 shows mesh belt blow-drying device provided by the present invention.This mesh belt blow-drying device is in similar position to the mesh belt blow-drying device of aforementioned employing cylinder, also is positioned at the guipure below, and it mainly comprises air knife and support 6, and wherein air knife is made of cutter hub 5, air outlet 4 and air inlet (not shown) substantially.Fig. 5 is the rearview of mesh belt blow-drying device provided by the present invention, can see therein the air inlet 7 of air knife, and this air inlet is connected with the compressed air piping of spraying equipment
Also show support 6 in Fig. 3, it is used as the supporter of air knife.Preferably, air knife can be fixed on the support 6, but this is not necessarily necessary.The height of support 6 can be set to about 750 centimetres, so that the air outlet of air knife can be aimed at guipure at the middle part of guipure mobile route substantially.As previously mentioned, mesh belt blow-drying device is worked under acid environment usually, so air knife and support preferably all adopt resistant material to make.
Compare with the mesh belt blow-drying device of the employing cylinder of routine, the device of employing air knife provided by the present invention at first is decreased significantly at cost.Except the cost of air knife itself far below the cylinder, mesh belt blow-drying device provided by the present invention does not need inductor, so has greatly simplified the expense of software control yet.As previously mentioned, what air knife can carry out that the whole network band covers dries up, and it dries up the effect that dries up that effect is better than cylinder far away, thus the guipure dripping phenomenon will be improved significantly, correspondingly so that also greatly improve the useful life of equipment.In addition, owing to adopting the structure of air knife to avoid moving around of tracheae, the probability that tracheae damages also reduces thereupon, and this also descends the plant maintenance amount greatly.
Should be noted that above embodiment is only in order to technical scheme of the present invention to be described but not limit it.Although with reference to above-mentioned embodiment the present invention is had been described in detail; those of ordinary skill in the art is to be understood that; still can make amendment or the part technical characterictic is equal to the specific embodiment of the present invention and replace and do not break away from essence of the present invention, it all be encompassed in the scope that the present invention asks for protection.
