Embodiment
Alignment liquid nozzle provided by the invention is mainly used in liquid crystal panel and makes field, for carrying out the coating of alignment liquid.Alignment liquid nozzle provided by the invention has the ejiction opening of a slit-type, and the length of ejiction opening is not less than the width of substrate.Like this, the alignment liquid nozzle, is uniformly distributed on substrate for continual continuously at the alignment liquid to the substrate ejection.Simultaneously, every alignment liquid of ejection all with substrate with wide, this is uniform with regard to make the alignment liquid sprayed under Width.While using the alignment liquid nozzle of this kind of structure, only need the ejiction opening that the alignment liquid of set amount is slot-shaped from this ejection can realize uniform coating, simplified the operating process of coating.The structure that distance between two plates reduces has gradually increased the stability of this alignment liquid nozzle arrangements, has improved its serviceable life.
With reference to figure 1, alignment liquid nozzle 10 provided by the invention is suspended at the top of substrate 20.Substrate 20 carries out translation along a direction, makes alignment liquid nozzle 10 alignment liquid can be coated on to the surface of whole substrate 20.Alignment liquid nozzle 10 is being arranged at the inlet 110 be connected with the pay-off of carrying alignment liquid away from substrate 20 1 ends, its end near substrate 20 is provided with for the ejiction opening 120 to substrate 20 ejection alignment liquids.Inlet 110 is connected with ejiction opening 120.During the coating alignment liquid, by pay-off, the alignment liquid of predetermined amount is delivered in inlet 110, and sprays to substrate 20 by ejiction opening 120.
With reference to figure 2, alignment liquid nozzle 10 provided by the invention comprises the first side plate 111 and the second side plate 112 be oppositely arranged.The first side plate 111 comprise be positioned at relative both sides first on along 1111 and first time along 1112.The second side plate 112 on comprising respectively with first along 1111 and first time along on 1112 corresponding second along 1121 and second time along 1122.Be formed with the ejiction opening 120 for spraying alignment liquid along 1112 and second time between 1,121 first time, ejiction opening 120 is slit-shaped, and slit can be linear, waveform or arc.Ejiction opening 120 is not less than the width of substrate 20 along the length on substrate 20 Widths, the projected length of ejiction opening 120 on the plane with the perpendicular direction of substrate 20 translation direction is not less than the length of substrate 20 projection on this plane.Like this, the alignment liquid of alignment liquid nozzle 10 ejections is along uninterrupted and even continuously on the Width of substrate 20.In order not cause the waste of alignment liquid, the Design of length of ejiction opening 120 is become to identical with the width of substrate 20.In this embodiment, in the first side plate 111 and the second side plate 112 away from an end interval of substrate 20 certain distance formed the space with opening with this, can be used as inlet 110.In other embodiment, the first side plate 111 and the second side plate 112 all can be parallel to substrate 20 and arrange, and ejiction opening 120 also can be used as inlet 110.In the present embodiment, the first side plate 111 and the second side plate 112 can be the vertical bar shaped tabular, and it can be more than or equal to the width of substrate 20 along the length on substrate 20 Widths.
The alignment liquid space that holds injection for alignment liquid nozzle 10 is also had, two side in relative position in two side in relative position in the first side plate 111 and the second side plate 112 can be bonded together, can engage fully, also can partly engage, so just formed a container cavity be connected between inlet 110 and ejiction opening 120, for holding the alignment liquid of injection, can also make alignment liquid along diffusion on the length direction of ejiction opening 120 evenly.
For the structure that makes alignment liquid nozzle 10 is more stable, and be convenient to fix, the first side plate 111 and the second side plate 112 be designed to: on first along on 1111 and second, along the distance between 1121, being greater than first time along 1112 and second time along the distance between 1122.
In the present embodiment, more even for the alignment liquid that makes on substrate 20 coating, and reduce the technological process of coating, scraper 130 is arranged on to a side of alignment liquid nozzle 20, with the second side plate 112, be fixedly connected with.In the present embodiment, scraper 130 is obliquely installed and make its side away from described the second side plate 112 extend.In order to simplify, manufacture and packaging technology, scraper 130 can be one-body molded with the second side plate 112.More preferably, the first side plate 111, the second side plate 112 and scraper 130 structure that is formed in one.The length of scraper 130 is consistent with the length of ejiction opening 120.
The present invention also provides the second embodiment.With reference to figure 3, the difference of this embodiment and the first embodiment only is: alignment liquid nozzle 10 also comprises that the first web joint 114, the first web joints 114 are connected to first time along 1112 and second time along between 1122, and ejiction opening 120 is opened on this first web joint 114.
The present invention also provides the 3rd embodiment.With reference to figure 3, the difference of this embodiment and the first embodiment is: at the first side plate 111 and the second side plate 112, away from an end of this substrate 20, the second web joint 113 is set.The second web joint 113 can be fixedly connected between the first side plate 111 and the second side plate 112.Offer the inlet 110 of at least one through hole as alignment liquid on the second web joint 113.The first side plate 111, the second side plate 112 and the second web joint 113 surround a conveying passage (not label) for being communicated with inlet 110 and ejiction opening 120.In order to simplify manufacture craft, preferably selecting is that the first side plate 111, the second side plate 112 and the second web joint 113 is one-body molded.Certain the second web joint 113 also can be rotationally connected with one of them of the first side plate 111 or the second side plate 112, goodly in hinged mode, is rotationally connected, and when needs inject alignment liquid, opens this second web joint 113 and gets final product.Be understandable that and the structure of the alignment liquid nozzle 10 in the 3rd embodiment and the second embodiment can also be carried out in conjunction with forming new alignment liquid nozzle arrangements.
Alignment liquid nozzle 10 provided by the invention can realize realizing continuous continual hydrojet on the Width of substrate 20.Make like this alignment liquid consumption at every turn be coated on substrate 20 identical and be evenly distributed.Simultaneously, be provided with scraper 130 in a side of alignment liquid nozzle 10, when the alignment liquid nozzle is coated with, this scraper 130 can be hung the alignment liquid on bottle substrate 20 in time, and coating is become evenly, smooth, guarantee to a certain extent the quality of production, improved production efficiency, reduced production cost.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
