Abstract
An ink-jet system comprises an ink pond in which the ink height is kept constant; an ink-jet head which is connected with the ink pond; the ink in the pond can be delivered to the ink-jet head and the ink-jet head can be moved vertically; when the ink-jet head is spraying ink, the ink-jet head is kept at the working height vertically; a valve is equipped between the ink pond and the ink-jet head; when the ink-jet head moves vertically, the valve is closed while the ink-jet head is kept at the working height, the valve is open; in this way, the ink can be delivered from the ink pond to the ink-jet head.
Description
Technical field
The present invention relates to a kind of ink-jet system, especially for the ink-jet system of making colored filter.
Background technology
Because LCD (Liquid Crystal Display, LCD) liquid crystal in is the assembly of non-active illuminating, must see through backlight light source is provided, the GTG that collocation drive integrated circult and liquid crystal control form black, white dichromatism shows, red (R), green (G), indigo plant (B) three kinds of color layers of seeing through colored filter (Color Filter) again provide form and aspect, form colored display frame, so colored filter is the key part and component of LCD colorize.
Ink ejecting method sprays in the black matrix" on a substrate simultaneously for the ink that uses an ink discharge device and will contain the RGB color layers, and the dehydrated back of ink droplet forms painted RGB color layers pattern on this substrate.Use ink ejecting method can once form the RGB color layers, make preparation process simplify in a large number, cost significantly reduces.Ink ejecting method has plurality of advantages such as processing procedure simplification, environmental protection, conservation.So in the preparation colored filter, the use of ink-jet system more and more widely.
In ink-jet system,, often need keep the constant pressure differential between ink reservoir and the ink gun in order to keep the good ink-jet state of ink gun.Only, in ink-jet, ink gun often needs vertical direction (Z axle) upper and lower displacement, as returning mechanical origin etc. along the Z axle.In general ink-jet system, the change of ink gun height can cause that the pressure differential between ink reservoir and the ink gun changes, thereby cause a large amount of ink leaks of ink gun, perhaps suck-back air bound nozzle, and then influence the ink-jet effect, and the increase ink jet head maintenance time.
Summary of the invention
In view of this, be necessary to provide a kind of ink-jet system, when ink gun when vertical direction moves up and down, a large amount of ink leaks can not take place in ink gun, perhaps the phenomenon of suck-back air bound nozzle.
A kind of ink-jet system, it comprises: the ink height keeps constant in the ink reservoir, this ink reservoir; One ink gun, this ink gun is connected with this ink reservoir, so that ink can be delivered to this ink gun in the ink reservoir, this ink gun can move along vertical direction, when the ink gun ink-jet, this ink gun is in the working depth on the vertical direction; Be provided with a valve between this ink reservoir and this ink gun, when ink gun when vertical direction moves, this valve closing, when ink gun is in working depth, this valve opening, thus ink can be delivered to ink gun from ink reservoir.
Compared to prior art, in the ink-jet system of present embodiment, a valve is set on the pipeline between ink reservoir and the ink gun, when ink gun is in working depth, valve opening; When ink gun when vertical direction moves up and down, valve closing, thus avoid ink gun in the process that moves up and down, a large amount of ink leaks take place, perhaps suck-back air bound nozzle, and then keep good ink-jet effect, reduce the ink jet head maintenance time, improve the utilization rate of board.
Description of drawings
Fig. 1 is the floor map of ink-jet system embodiment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
As shown in Figure 1, this ink-jet system 100 comprises: an ink reservoir 10; One is arranged at the ink height sensor 12 in the ink reservoir; One ink gun 14; One pipeline 16; Be arranged at the valve 18 on the pipeline 16; Control device 20.Ink reservoir 10 is connected by pipeline 16 with ink gun 14.Control device 20 electrically connects with valve 18, so that it is controlled.
The height of ink keeps a steady state value in the ink reservoir 10, and is poor thereby ink reservoir 10 and ink gun 14 are kept constant compression force.When sensor 12 senses the ink height when being lower than steady state value, ink reservoir can automation replenish ink, makes the ink height return to steady state value.Ink height sensor 12 can use ultrasonic position sensor (Ultrasonic Displacement Sensor) or pressure inductor (Pressure Sensor).In the present embodiment, adopt the ultrasonic position sensor.
When ink gun 14 was positioned at working depth, control device 20 maintained the state of often opening with valve 18, thereby ink can be delivered to ink gun 14 from ink reservoir 10.When ink gun 14 moves up and down along vertical direction, when rising or descending, control device 20 cuts out valve 18, thereby avoids a large amount of ink leaks of ink gun, perhaps suck-back air bound nozzle.When ink gun 14 was got back to working depth, control device 20 was with Open valve 18, thereby ink can be delivered to ink gun 14 from ink reservoir 10.
Valve 18 can be pneumatic operated valve, magnetic valve or check valve etc.At present embodiment, valve 18 is a check valve, can prevent that ink from flowing to ink reservoir 10 from ink gun 14.Valve 18 is that the material by Teflon anti-solvent corrosions such as (Teflon) makes.
Compared to prior art, in the ink-jet system of present embodiment, a valve is set on the pipeline between ink reservoir and the ink gun, when ink gun is in working depth, valve opening; When ink gun when vertical direction moves up and down, valve closing, thus avoid ink gun in the process that moves up and down, a large amount of ink leaks take place, perhaps suck-back air bound nozzle, and then keep good ink-jet effect, reduce the ink jet head maintenance time, improve the utilization rate of board.
In addition, those skilled in the art can also change in spirit of the present invention, and certainly, these change according to the present invention's spirit, all should be included within the present invention's scope required for protection.
