Because the fast development of computer Related product, flat-panel screens have become the main flow that present screen shows.And organic electric exciting light-emitting diode because simple in structure, processing procedure is easy, drive current potential low, no visual angle restriction, and is beneficial to the application of full-color display, is the new trend that develops of flat-panel screens at present.Be with the single layer structure element of conjugated polymer as organic film material, its main process technique is in rotation coating (Spin coating) or ink jet printing (Ink jet printing) mode conjugate polymer material to be applied on the substrate; And, be one of present very important processing procedure wherein with the most suitable large scale of ink jet printing mode and a large amount of production.Therefore, the control for the ink jet printing process quality also is a considerable step in the organic electric exciting light-emitting diode manufacturing process.
In ink jet process,, cause the ink gun spray nozzle clogging easily if in the ink when containing impurity or bulky grain suspension, ink droplet can't be sprayed, or cause ink droplet inhomogeneous, the part picture element can't be filled up or irregular, cause the defective of luminescent panel easily, and reduce the life-span of ink gun.Known settling mode is with a large amount of inks or solvent washing, and quite wasted ink increases cost.The opposing party's rule is to filter out bulky grain suspension or impurity with filter disc (filter), but the method can not prevent ink to kill and block nozzle, still can cause panel defect to produce.Therefore, in the ink-jet processing procedure, still need at present and want a kind of new clean method, can effectively solve the spray nozzle clogging situation that the bulky grain suspension causes, and can avoid the nozzle ink to kill, prolong the service life of ink gun, increase the acceptance rate of ink-jet processing procedure; Also need not wash away tamper on the other hand, and then reduce production costs with ink.
The utility model content
Main purpose of the present utility model provides a kind of ink gun cleaning device of organic electroluminescence panel ink-jet processing procedure, can clean the nozzle of small size, and can reduce or avoid the nozzle ink inside to kill and cause spray nozzle clogging.
For reaching above-mentioned purpose, the utility model is the ink gun cleaning device that is relevant to a kind of organic electroluminescence panel ink-jet processing procedure, be to cooperate an ink gun and a cleaning solution to use, mainly comprise: an ink gun putting groove, with ccontaining this ink gun and this cleaning solution, to clean this ink gun; And a ultrasonic generator, be to be connected with this ink gun putting groove or to be positioned at this ink gun putting groove, so that being provided, the enough energy of this cleaning solution clean this ink gun.
The cleaning device of described organic electroluminescence panel ink-jet processing procedure, wherein the size of this ink gun putting groove just can ccontaining this ink gun.
The cleaning device of described organic electroluminescence panel ink-jet processing procedure, wherein this cleaning solution is deionized water, organic solvent or ink.
The cleaning device of described organic electroluminescence panel ink-jet processing procedure, wherein the ultrasonic frequency that produced of this ultrasonic generator is 17KHz to 100KHz.
The cleaning device of described organic electroluminescence panel ink-jet processing procedure, wherein the ultrasonic frequency that produced of this ultrasonic generator is 600KHz to 1MHz.
The cleaning using method of the utility model organic electroluminescence panel ink-jet processing procedure, be to cooperate an ink gun to use, mainly comprise the following steps: at first, provide and comprise an ink gun putting groove, a cleaning solution, and the ink gun cleaning device of a ultrasonic generator, wherein this ultrasonic generator is to be connected with this ink gun putting groove; Afterwards, this ink gun is placed this ink gun putting groove, and the nozzle on this ink gun is positioned under the cleaning solution liquid level; The person of connecing starts this ultrasonic generator of this ink gun cleaning device, makes this cleaning solution cooperate ultrasonic energy to clean this ink gun; At last, this ink gun is taken out in this ink gun putting groove.This ink gun can optionally be deposited in the ink gun putting groove that contains clean cleaning solution.
From the above, the utility model cleans ultrasonic principle for the first time and introduces in PLED or the OLED ink-jet processing procedure, if just carry out this cleaning after each ink-jet processing procedure finishes, plugging rate is significantly reduced, and significantly promotes panel and makes acceptance rate.In addition, cleaning method of the present utility model need not use the tamper on a large amount of inks or the organic solvent washer jet, avoids the waste of ink, can significantly reduce cost of manufacture.The more important thing is, the utility model device can be used as the accumulator tank of ink gun simultaneously, compare with traditional ink gun accumulator tank or cleaning method, the utility model has concurrently and cleans and memory function, make ink gun after cleaning, can directly deposit in clean organic solvent, ink or the deionized water, avoid because the ink on the nozzle is killed and resulted in blockage, it is quite convenient to use.Device that the utility model proposed and cleaning method not only have multi-functional, the easy advantage of step, and effect are quite good.
