The specific embodiment
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 is inputted to described second-rate bodily form coelosis 6 is (as polyimides, Polyimide, hereinafter to be referred as PI liquid) compressed air of inputting to described second-rate bodily form coelosis 6 with described compressed air inlet pipe 3 mixes and forms two fluids that include PI liquid of High Rotation Speed, then spray by described rotary nozzle 8 at described second-rate bodily form coelosis 6.As shown in Figure 2, this alignment films apparatus for coating also comprises the mask plate 20 being used in conjunction with two fluid makers, and 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 the position that does not need spraying on substrate 30, 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 that substrate 30 needs spraying.
The PI liquid of needs spraying is carried out atomization processing by alignment films apparatus for coating.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.In the present invention, by high velocity air, PI liquid is dispersed into droplet, be atomized spray through the High Rotation Speed of nozzle again, viscosity claimed range for PI liquid is so not strict, the PI liquid using for current product line, this device can use completely, even if the relatively liquid of thickness, can deal with by the flow of the pressure of increasing Compressed Gas and minimizing PI liquid.Described alignment films apparatus for coating by two fluid makers by generate rotation PI liquid two fluids under the booster action of mask plate, under fast rotational effect by rotary nozzle, be sprayed on the assigned address of substrate, form the controlled even orientation rete of a layer thickness.Wherein, the thickness of spraying alignment films can be controlled by the time of spraying.
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 of controlling the PI liquid entering by liquid feed pipe 1 of fluid flowmeter 5, air gauge 4 can measure compressed-air actuated air pressure.The present invention can regulate the atomizing effect in rotating speed and the spraying process of PI liquid two fluids by fluid flowmeter 5 and air gauge 4.
Wherein, described alignment films apparatus for coating is also provided with back shaft 7; In described rotary nozzle 8, establish shower nozzle cavity (not shown); 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, can be provided with and form two fluid issuings in a 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 described rotary nozzle 8 is carried out to spacing nut 10, can realize easily the replacing of rotary nozzle 8 by this nut 10.
Further, in described rotary nozzle 8, be provided with ramp way 81 and the nozzle 9 being connected with described ramp way 81; PI liquid two fluids in described shower nozzle cavity spray by described ramp way 81 and nozzle 9, and PI liquid two fluids drive described rotary nozzle 8 to rotate by pushing described ramp way 81.Be rotated spraying in order to realize the two fluids rotary nozzle 8 of flowing through, PI liquid two fluids are 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 fluids, rotary nozzle 8 can be realized fast rotational, makes two fluids of the PI liquid spraying out more even.
Particularly, described rotary nozzle 8 is along being circumferentially evenly provided with multiple nozzles 9.For example, 9 nozzles are set on rotary nozzle, are evenly arranged on this rotary nozzle around.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 can pass into cleaning agent by liquid ceanser feed pipe 2 and clean rotary nozzle 8, for example ramp way and nozzle, after cleaning, before formal spraying, must carry out rinse spraying a period of time, in case ramp way and nozzle interior that cleaning agent residues in rotary nozzle affect coating quality.
Further, in order to realize better spraying effect, two fluid makers can also be arranged on the board that can move freely 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 like this spraying of sliding.
Further again, as shown in Figure 7, mask plate 20 correspondences are arranged on described substrate 30 tops.Open region 202 thickness of described mask plate 20 are greater than blocked area 201 thickness of this mask plate 20; In described blocked area 201, be provided with the groove 203 for storing two fluids.Design is 203 li of grooves for two fluids that are sprayed at blocked area in spraying process being stored in to blocked area 201 like this, makes it can not affect spraying effect owing to accumulating in 202 edges, mask plate 20 open region.
Above embodiment is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
