Fig. 1 is the concept map of the example of expression dispenser of the present invention.This dispenser is used for the discharge material being discharged to the discharge object and the tiny flaw portion of this discharge object being revised, and has container 1, discharges pin 2 and discharge control apparatus 3.
Described container 1 is revise to discharge the groove jar that the discharge material of the defective part of object is stored, and is the occasion of filter substrate discharging object for example, and the colored ultraviolet hardening resin 4 that stores colour filter is as discharging materials.This colour ultraviolet hardening resin 4 hardens by the ultraviolet ray irradiation, and the Volume Changes during sclerosis is a few percent, so control coating thickness easily.With respect to this, also can use thermosetting resin as discharging material, but this thermosetting resin, because the Volume Changes during its sclerosis is 50% approximately, so have following situation: for the coating thickness that obtains to stipulate, must discharge about 2 times thermosetting resin of coating thickness, the defective part of thermosetting resin after the finishing overflowed.Therefore, in the following description, to using filter substrate as discharging object, using colored ultraviolet hardening resin 4 to narrate as the situation of discharging material.
Top ends at described container 1 is provided with discharge pin 2.This discharge pin 2 is to be made by the glass tube that makes colored ultraviolet hardening resin 4 be discharged to the defective part 11 (with reference to Fig. 4) of filter substrate.In this occasion, the amount of the colored ultraviolet hardening resin 4 that the defect correction of colour filter is required is micro-, promptly when the thickness with colour filter make 2 μ m, when the finishing size for example is 50 μ m * 50 μ m, the amount of required colored ultraviolet hardening resin 4 is 5pL, when being of a size of 100 μ m * 100 μ m, the amount of required colored ultraviolet hardening resin 4 is 20pL, therefore, by the glass tube after the thermoplastic is elongated, discharge pin 2 forms needle point 2a and becomes than the thin shape of pin body 2b as shown in Figure 2.The bore of glass tube also elongates along with thermoplastic and drawing-down and diminishes, and can easily form inside diameter D and be several microns to tens microns thinner needle point 2a.
For for referencial use, the relation between the required discharge number of times of the finishing portion of three kinds of sizes that the inside diameter D that Fig. 3 has represented to discharge pin 2 is different with each discharge rate V and filling.Discharge rate V is according to viscosity of air pressure, efflux time and colored ultraviolet hardening resin 4 etc. and different, but, be to calculate as the amount that the colored ultraviolet hardening resin 4 of the length L part that is in needle point 2a shown in Figure 2 is discharged because of discharging operation at this.
In the occasion that can select described finishing size according to the size of defective part 11, when selectable finishing size for example is 50 μ m * 50 μ m, 70 μ m * 70 μ m, 100 μ m * 100 μ m, about inside diameter D is the discharge pin 2 of 3 μ m～9 μ m, and the discharge number of times that then can carry out filling to the finishing portion of each size just as shown in Figure 3.In the figure, the regional A that oblique line is represented is that the discharge rate of comparing once with the volume of the finishing portion of institute correspondingly-sized is too much, overflows and out of use zone from described finishing portion so be colored ultraviolet hardening resin 4.In addition, area B is must carry out the discharge more than 11 times, the unfavorable zone that the finishing beat is grown repeatedly for each finishing portion being carried out filling.
According to Fig. 3, available 1 discharge pin 2 is corresponding with the finishing portion of described three kinds of sizes, is to be the discharge pin 2 of 6 μ m～9 μ m in the figure by the inside diameter D that thick dashed line surrounded.Therefore, in this occasion, the internal diameter that discharge pin 2 forms needle point 2a is 6 μ m～9 μ m.Described finishing size is for example selected 50 μ m * 50 μ m when the size of defective part 11 is 30 μ m≤S＜50 μ m, select 70 μ m * 70 μ m when being 50 μ m≤S＜70 μ m, selects 100 μ m * 100 μ m when being 70 μ m≤S＜100 μ m.
As shown in Figure 1, described container 1 is connected with discharge control apparatus 3 by pipe arrangement 6.The purposes of this discharge control apparatus 3 is that with the colored ultraviolet hardening resin 4 of positive pressure in being stored in described container 1, this discharge control apparatus 3 has air accumulator 7, timer 8, magnetic valve 9 and flow control valve 10.Here, the purposes of air accumulator 7 for example is the temporary transient air of being supplied with by air pump that stores, and air accumulator 7 is connected with magnetic valve 9 by flow control valve 10.In addition, the purposes of timer 8 is to connect switch with the predefined time to make magnetic valve 9 energisings, and the purposes of magnetic valve 9 is to make valve carry out on-off action according to being switched on or switched off of energising.Thus, discharge control apparatus 3 carries out such action: open with the time chien shih magnetic valve 9 that timer 8 sets, utilizing 10 pairs of flow control valves temporarily to be stored in air in the air accumulator 7 carries out flow-control and by pipe arrangement 6 it is supplied in the described container 1, utilization imports to the air positive pressure in the container 1, and colored ultraviolet hardening resin 4 is discharged in right amount from the discharge pin 2 of container 1.
So, adopt dispenser of the present invention,, form elongation of the glass tube after the thermoplastic and needle point 2a thinner, then can easily form inside diameter D and be several microns to tens microns discharge pin 2 owing to will discharge pin 2 and make glass tube.Therefore, can discharge the colored ultraviolet hardening resin 4 of trace, the tiny flaw portion of available dispenser correction colour filter.
Below, with reference to Fig. 4 and Fig. 5 defect correcting method with above-mentioned dispenser correction colour filter defective part is described.
At first, in the 1st step, for example observe object lens with the CCD camera by the diagram abridged and detect defective part on the colour filter, for example the gauge that is located on the object lens of utilization is measured the size of defective part.
In the 2nd step, select to repair size according to the size of the defective part of colour filter 5.This selection is carried out with the slit that laser beam passed through by selecting finishing.For example, when the big or small S of defective part is 30 μ m≤S＜50 μ m, select the slit of 50 μ m * 50 μ m, when being 50 μ m≤S＜70 μ m, select the slit of 70 μ m * 70 μ m, when being 70 μ m≤S＜100 μ m, select the slit of 100 μ m * 100 μ m.
In the 3rd step, shown in Fig. 4 (a), by the slit of described selection, with the stipulated time to for example 532nm of defective part 11 irradiation finishing usefulness or the laser beam 12 of 355nm, defective part 11 obtains finishing and increases (with reference to Fig. 5 (a)).This finishing is carried out for following situation, that is: in order to remove the thrust attached to foreign matter on the colour filter 5 etc.; And, considered to have a mind to increase defective part 11 from the discharge rate of the colored ultraviolet hardening resin 4 of discharge pin 2 discharges by a discharging operation for the colored ultraviolet hardening resin 4 that flows into defective part 11 is not overflowed from defective part 11.
In the 4th step, shown in Fig. 4 (b), the needle point 2a that discharges pin 2 is positioned at defective part 11.Under this state, omit illustrated discharge and begin switch if press, the timer 8 of discharge control apparatus 3 then shown in Figure 1 produces action, and magnetic valve 9 is opened with the predefined time.Thus, compressed air is from air accumulator 7, carried out the flow adjustment and by pipe arrangement 6 it supplied in the container 1 by 10 pairs of compressed air of flow control valve.And the malleation that is produced by air is endowed the colored ultraviolet hardening resin 4 in the container 1, and colored ultraviolet hardening resin 4 is from discharging on the defective part 11 after pin 2 is discharged to finishing (with reference to Fig. 5 (b)).In this occasion, be the discharge pin 2 of 6 μ m when for example using inside diameter D, when selecting 50 μ m * 50 μ m as the finishing size according to the big or small S of defective part 11, as shown in Figure 3, carry out 1 time discharging operation, when selecting 70 μ m * 70 μ m as the finishing size, carry out 4 times discharging operation, when selecting 100 μ m * 100 μ m, during as the finishing size, carry out 10 times discharging operation.
In the 5th step, shown in Fig. 4 (c),,, make colored ultraviolet hardening resin 4 sclerosis (with reference to Fig. 5 (c)) that are discharged on the defective part 11 for example with the laser beam 13 of stipulated time irradiation 355nm (ultraviolet ray) by described object lens.Thus, shown in Fig. 4 (d), the correction of defective part 11 finishes (with reference to Fig. 5 (d)).
In addition, in above-mentioned the 2nd step, can from predefined three kinds of finishing sizes, not select a kind of size according to the size of defective part 11 yet, and under the situation of knowing 1 discharge rate and coating thickness in advance, the no matter size of defective part 11 and the finishing size calculated of the described discharge rate of set basis and coating thickness all the time.Specifically, when for example using inside diameter D to be the discharge pin 2 of 19 μ m, 1 discharge rate is the occasion of 19.8pL as shown in Figure 3, and no matter the size of defective part 11 all can be set at 100 μ m * 100 μ m all the time with the finishing size and repair.In this occasion, can pass through 1 discharging operation, roughly be full of finishing portion with colored ultraviolet hardening resin 4.
So, adopt defect correcting method of the present invention, owing to can from predefined a plurality of sizes, select one of them with finishing defective part 11 according to the size of defective part 11, thereby can reduce to repair size, and can reduce the discharge rate of colored ultraviolet hardening resin 4 in defective part 11 less occasions.The use amount that therefore, can suppress the employed colored ultraviolet hardening resin 4 of defect correction of colour filter 5.
In addition, owing to the discharge number of times of setting according to the finishing size colored ultraviolet hardening resin 4 is discharged, thereby also available 1 finishing portion that discharges pin 2 corresponding to different size.
In addition, in the occasion of knowing 1 discharge rate and coating thickness in advance, if the no matter size of defective part 11 and the finishing size calculated of the described discharge rate of set basis and coating thickness all the time, then needn't measure the size of defective part 11, it is simple that the defect correction operation becomes.Therefore, can shorten the time of defect correction operation.
More than, illustrated filter substrate as the situation of discharging object, but be not limited thereto, for example also applicable to the defect correction of the film of wiring circuit etc.
