The specific embodiment
For the above-mentioned purpose, the feature and advantage that make the utility model are more obviously understandable, the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.Need to prove that each structure in the accompanying drawing is schematic rather than determinate, so that those of ordinary skills understand the principle of the utility model best, it is not necessarily drawn in proportion.
Fig. 1 and Fig. 2 show the existing guipure blow-dry device that spraying equipment adopted that is used for solar cell preparation, and wherein said spraying equipment can be a PV360 spraying equipment for example.As shown in Figure 1, guipure 3 can move 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.Said guipure blow-dry 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 parts such as jet tracheae 10, inductor 11,12 to constitute.When spraying equipment energising operate as normal, provide the compressed-air actuated magnetic valve of nozzle often to open, compressed air is communicated with nozzle through the tracheae that is connected with nozzle, and gas uninterruptedly is provided, and makes nozzle to blow continuously.The inductor at cylinder two ends provides signal, controls nozzle through nozzle mobile device and on the width of guipure, moves back and forth, and aims at guipure simultaneously and blows, and makes the cylinder that nozzle is housed accomplish the task of drying up guipure.
Guipure width described in this paper be meant with the guipure plane on the perpendicular direction of its moving direction.The moving direction of guipure illustrates with arrow in Fig. 1.Single structure of nozzle has the very low efficient that dries up, and usually can cause drying up inhomogeneous or dry up incomplete.Under the situation that nozzle can't dry up guipure fully, 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 each 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 operate as normal.In addition, the nozzle near guipure also is easy to be corroded.Can see that from Fig. 2 a part of tracheae is coated by gantry 4, and gantry 4 need be followed nozzle mobile device and moved around, the tracheae that therefore is positioned at is wherein standing to be very easy to fracture under this reciprocating situation for a long time.
Fig. 3 shows the guipure blow-dry device that the utility model provides.This guipure blow-dry device is in similar position with the guipure blow-dry 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 up of cutter hub 5, air outlet 4 and air inlet (not shown) substantially.Fig. 5 is the rearview of the guipure blow-dry device that provides of the utility model, can see the air inlet 7 of air knife therein, and this air inlet is connected with the compressed air piping of spraying equipment
Cutter hub 5 shown in Figure 3 is cylindrical substantially, along the closed at both ends of its length direction, but is understood that the cutter hub shape must not be columniform.Effective air-out position of air outlet 4 is elongated on the whole, can see that from the detail view of Fig. 4 air outlet 4 can be made up of row's exhaust vent.In other embodiments, air outlet 4 also can be to be made up of the elongate slit shape exhaust vent that is communicated with.This air outlet is set to substantially towards guipure 3, and its length is set to identical substantially with the width of guipure 3.In addition, this air outlet preferably also is set on the width of guipure 3 parallel with guipure.Generally speaking; The translational speed of guipure is about 13.33cm/s; So single moving nozzle is difficult to guipure is thoroughly dried up, and adopts layout shown in Figure 3, the air outlet of air knife has all covered whole guipure basically; Therefore can blow afloat to guipure incessantly, this will bring and well dry up effect.Can also see that from Fig. 3 and Fig. 4 air outlet 4 is arranged to and protrudes in cutter hub 5 so that it more approaches guipure, and can more cold wind be blown to guipure 3 with bigger pressure, brings the better effect that dries up thus.Such layout also makes air knife in the long-term course of work, be not easy distortion.
In Fig. 3, also show support 6, it is used as the supporter of air knife.Preferably, air knife can be fixed on the support 6, but that this is not necessarily is necessary.The height of support 6 can be set to about 750 centimetres, makes the air outlet of air knife to aim at guipure at the middle part of guipure mobile route substantially.As previously mentioned, the work under acid environment usually of guipure blow-dry device, so air knife and support preferably all adopt resistant material to make.
Compare with the guipure blow-dry device of the employing cylinder of routine, the device of the employing air knife that the utility model provided at first has remarkable decline on cost.Except the cost of air knife itself far below the cylinder, the guipure blow-dry device that the utility model provided 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 make also improve greatly the service life of equipment.In addition, owing to adopt 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 the above specific embodiment only in order to the explanation the utility model technical scheme but not limit it.Although the utility model is specified with reference to the above-mentioned specific embodiment; Those of ordinary skill in the art is to be understood that; Still can make amendment or the part technical characterictic is equal to replacement and does not break away from the essence of the utility model the specific embodiment of the utility model, it all be encompassed in the scope that the utility model asks for protection.
