Please with reference to Fig. 2 to Fig. 5, filling device of the present invention comprises fills device 1, filling device travel mechanism 2, worktable 3, movable workbench mechanism 4 and ranging localization assembly.Filling device travel mechanism 2 drives filling device 1 to move; Worktable 3 is for placing infrabasal plate 8 and worktable 3 drives it to move by movable workbench mechanism 4; The distance that ranging localization assembly is used for filling between device 1 and infrabasal plate 8 is measured, is controlled, and it comprises the upper camera 5, the laser sensor 6 that are positioned at and fill above device 1 and is positioned at the side camera 7 of filling device 1 side.
Filling device 1 has the accommodating cavity 11 for accommodating ink, accommodating cavity 11 one side is provided with the micropin 12 of array arrangement, another side is provided with the ink inlet (not drawing in figure) flowed into for ink, micropin 12 has the inner chamber 12a for ink circulation, inner chamber 12a one end is ink export, and the other end communicates with accommodating cavity 11.Preferably, the inner chamber 12a of accommodating cavity 11 and micropin 12 has water-wet behavior.
Fig. 1 is the process flow diagram of the wetting ink fill method of the present invention's electricity, and Fig. 6 (a) to Fig. 6 (d) is constitutional diagram corresponding to each step of the wetting ink fill method of the present invention's electricity.Please with reference to Fig. 1 to Fig. 6 (d), the wetting ink fill method of the present invention's electricity comprises the steps:
S1: preparation has the filling device 1 of array micropin 12 and has the infrabasal plate 8 of pixel compartments 81.The needle point perforate size of micropin 12 can control the size of ink droplet, and then control the quantity of ink of filling, in step sl can according to the size of pixel compartments and needing fill quantity of ink number select to fill device 1 accordingly, so can solve quantitative filling and the filling problem to different size pixel compartments.Fill device 1 to be fixedly connected with filling device travel mechanism 2, infrabasal plate 8 is fixedly connected with worktable 3 and provides motion-promotion force by movable workbench mechanism 4.Filling device travel mechanism 2 and movable workbench mechanism 4 are preferably by three axle travel mechanisms of servo motor driven, and the electricity that this makes it possible to meet various sizes soaks the ink filling demand of display screen.But in various embodiments, for the consideration of production, manufacturing cost, filling device travel mechanism 2 also can be made only to have horizontally moving functions, and movable workbench mechanism 4 then only has VTOL (vertical take off and landing) function.
S2: make the inner chamber 12a of micropin 12 be full of ink.Pressurize to the ink in accommodating cavity 11, because accommodating cavity 11 communicates with the inner chamber 12a of micropin 12, ink is full of the inner chamber 12a of each micropin 12 under pressure.
S3: mobile filling device 1 or infrabasal plate 8, makes micropin 12 and pixel compartments 81 align.Preferably, the distance between adjacent micropin 12 equals the distance at neighbor lattice 81 center.Electricity for reduced size soaks display screen, and micropin 12 and pixel compartments 81 one_to_one corresponding can be made to carry out ink filling; And device 1 can be filled by moving in parallel for the display screen of oversize, the mode of taking step-by-step movement gradation to fill completes and fills the ink of display base plate.
S4: make needle point place form ink droplet 91 to the inner chamber 12a of micropin 12 pressurization, until ink droplet 91 drops to pixel compartments 81 from micropin 12 or ink droplet 91 to contact with infrabasal plate 8 and to be adsorbed in pixel compartments 81.If the bottom surface distance of the needle point of micropin 12 and pixel compartments 81 is relatively far away, ink droplet 91 departs from needle point under gravity and falls in pixel compartments 81, and then completes the filling of ink; If the bottom surface distance of the needle point of micropin 12 and pixel compartments 81 is relatively near, then ink droplet 91 just can contact with pixel compartments 81 before not departing from needle point, due to the hydrophobic property of infrabasal plate 8, ink droplet 91 can be adsorbed in pixel compartments 81 automatically, namely completes the filling of ink.
Please with reference to Fig. 4 and Fig. 6 (a), further, in step s 2, to the pressurizes ink of micropin 12 inner chamber 12a, after all micropins 12 all evenly spray ink, then reduce pressure to reach needle point and be full of ink but the state that suspends of no drop.All micropins 12 all evenly spray ink, so just can ensure that the air in the inner chamber 12a of micropin 12 is got rid of completely, then are decompressed to the state of needle point no drop suspension so that fill the movement of device 1.
Please with reference to Fig. 2 and Fig. 3, further, in step s3, filling the first alignment mark 13 of device 1 and the second alignment mark 82 of infrabasal plate 8 are aligned micropin 12 and pixel compartments 81 are aligned.
Please with reference to Fig. 6 (b) to Fig. 6 (d), further, in step s 4 which, before the inner chamber 12a pressurization of micropin 12, Schilling is filled device 1 and is declined or make infrabasal plate 8 rise, so that ink droplet 91 accurately enters in pixel compartments 81; After treating that ink droplet 91 is placed in pixel compartments 81, then lift filling device 1 or reduce infrabasal plate 8.
Further, after step s4, then by water injecting mechanism water seal is carried out to pixel compartments 81 and upper cover plate and infrabasal plate 8 are encapsulated by pressure sensitive adhesive.
It should be noted that, electricity is wetting, and to have another name called electricity moistening, and the present invention is equally applicable to electro wetting liquid lens.
More than that preferred embodiment of the present invention is illustrated, but the present invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent distortion or replacement are all included in the application's claim limited range.
