Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
The present embodiment provides a kind of alignment films apparatus for coating, comprising: board (not shown); Two fluid makers are arranged on described board, and as shown in Figure 1, this two fluids maker comprises liquid feed pipe 1, compressed air inlet pipe 3, second-rate bodily form coelosis 6 and rotary nozzle 8; The alignment films solution that described liquid feed pipe 1 inputs to described second-rate bodily form coelosis 6 is (as polyimides, Polyimide, hereinafter referred to as PI liquid) compressed air that inputs to described second-rate bodily form coelosis 6 with described compressed air inlet pipe 3 mixed at described second-rate bodily form coelosis 6 and forms two fluids including PI liquid of High Rotation Speed, then being sprayed by described rotary nozzle 8.As shown in Figure 2, this alignment films apparatus for coating also comprise with two fluid makers with the use of mask plate 20, this mask plate 20 is provided with blocked area 201 and open region 202.The effect of mask plate 20 is in spraying process, block position substrate 30 not needing spray, it is corresponding with the design of substrate 30, accompanying drawing 3 is the schematic diagram after mask plate 20 is fitted with substrate 3, upper strata is mask plate 20, lower floor is substrate 30, and the open region 202 of mask plate 20 is the region of substrate 30 needs spraying.
Alignment films apparatus for coating carries out atomization process by needing the PI liquid of spraying.Atomization refers to by nozzle or with high velocity air and makes liquid dispersion become the operation of fine droplet.PI liquid changes into droplet through second-rate bodily form coelosis, nebulizes and ejects.By high velocity air, PI liquid is dispersed into droplet in the present invention, High Rotation Speed again through nozzle is atomized spray, viscosity requirement scope for PI liquid is so not strict, for the PI liquid producing line use at present, this device can use completely, even if compare the liquid of thickness, can be dealt with by the flow of the pressure and minimizing PI liquid that strengthen Compressed Gas.Described alignment films apparatus for coating by two fluid makers by generate rotation PI liquid two fluid under the booster action of mask plate, by under the fast rotational effect of rotary nozzle, be sprayed on the assigned address of substrate, form the even orientation rete that a layer thickness is controlled.Wherein, the thickness spraying alignment films controlled by the time sprayed.
Further, as shown in Figure 1, described liquid feed pipe 1 is provided with fluid flowmeter 5; Described compressed air inlet pipe 3 is provided with air gauge 4.The convenient quality controlling the PI liquid entered by liquid feed pipe 1 of fluid flowmeter 5, air gauge 4 can measure compressed-air actuated air pressure.The present invention regulates the atomizing effect in the rotating speed of PI liquid two fluid and spraying process by fluid flowmeter 5 and air gauge 4.
Wherein, described alignment films apparatus for coating is also provided with back shaft 7; Shower nozzle cavity (not shown) is established in described rotary nozzle 8; Described second-rate bodily form coelosis 6 is connected in relatively turnable mode with described shower nozzle cavity; Described rotary nozzle 8 is arranged on described back shaft 7 in the mode that can rotate around described back shaft 7.Particularly, formation two fluid issuing can be provided with in the side of second-rate bodily form coelosis 6, the side that described shower nozzle cavity is corresponding is provided with two fluid intakes, two fluid intakes and described two fluid issuings snap together, described second-rate bodily form coelosis 6 is communicated with described shower nozzle cavity, and is connected in relatively turnable mode.Further, described back shaft 7 is provided with and carries out spacing nut 10 to described rotary nozzle 8, can be realized the replacing of rotary nozzle 8 by this nut 10 easily.
Further, ramp way 81 is provided with in described rotary nozzle 8 and the nozzle 9 that is connected with described ramp way 81; PI liquid two fluid in described shower nozzle cavity is sprayed by described ramp way 81 and nozzle 9, and PI liquid two fluid drives described rotary nozzle 8 to rotate by the described ramp way 81 of extruding.Flow through rotary nozzle 8 carry out rotary spraying in order to two fluids can be realized, PI liquid two fluid is designed to ramp way 81 at the flowing through channel of rotary nozzle 8 inside, like this under the fast spraying extruding of PI liquid two fluid, rotary nozzle 8 can realize fast rotational, makes two fluids of the PI liquid sprayed out more even.
Particularly, described rotary nozzle 8 is circumferentially evenly provided with multiple nozzle 9.Such as, rotary nozzle arranges 9 nozzles, is evenly arranged on around this rotary nozzle.Certainly, the shape of nozzle and quantity can design according to actual needs.Preferably, as shown in Figure 4, Figure 5 and Figure 6, described nozzle 9 adopts line style nozzle, diamond pattern nozzle or circular nozzle.
Wherein, as shown in Figure 1, described two fluid makers also comprise liquid ceanser feed pipe 2, and described liquid ceanser feed pipe 2 is communicated with described second-rate bodily form coelosis 6.This alignment films apparatus for coating passes into cleaning agent by liquid ceanser feed pipe 2 and carries out cleaning rotary nozzle 8, such as ramp way and nozzle, after cleaning, rinse must be carried out and spray a period of time before formal spraying, in case cleaning agent residues in ramp way in rotary nozzle and nozzle interior affects coating quality.
Further, in order to realize better spraying effect, two fluid makers can also be arranged on and can move freely on the board of location.Described board is provided with the slide rail that can move freely, and described two fluid makers are arranged on described slide rail, can realize spraying of sliding like this.
Further again, as shown in Figure 7, mask plate 20 correspondence is arranged on above described substrate 30.Open region 202 thickness of described mask plate 20 is greater than blocked area 201 thickness of this mask plate 20; The groove 203 for storing two fluids is provided with in described blocked area 201.Such design is the groove 203 li in order to two fluids being sprayed at blocked area in spraying process being stored in blocked area 201, makes it can not affect spraying effect owing to accumulating in mask plate 20 edge, open region 202.
Above embodiment is only for illustration of the present invention; and be not limitation of the present invention; the those of ordinary skill of relevant technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
