Therefore, operator by the end of described injection nozzle 40 between described 1st transparent panel 51 and the 2nd transparent panel 52.Therefore, described resin passes through described vent valve 30 from resin supply unit 10 free-falling, and is expelled between described 1st transparent panel 51 and the 2nd transparent panel 52 by injection nozzle 40.At this, even if the Pressure generator that described injection nozzle 40 does not have other (such as, fixed displacement pump), the pressure produced according to discharging described resin from described resin supply unit 10 by free-falling mode, also can by resin injection between described 1st transparent panel 51 and the 2nd transparent panel 52, thereby, it is possible to form resin bed 53.
At this, described resin supplying step refers to the flow of the resin that confirmation is injected by described injection nozzle and makes to supply the quantitative resin set.With reference to Fig. 8, resin supplying step as above is described.
Fig. 8 is the precedence diagram that display utilizes the resin supplying step in the manufacture method of the transparent display screen of resin injection device of the present invention.
With reference to Fig. 8, described resin supplying step comprises: open supply pipe step S411, control described opening and closing device 13, and open described supply pipe 12, and thus, supply is stored in the resin of described resin service tank 11; Flow detection step S412, after described unlatching supply pipe step S411, detects the flow being injected into the resin of described 1st transparent panel 51 by described flowmeter 14; Setting flow determining step S413, compares the flow of the flow detected in described flow detection step S412 and setting; Close supply pipe step S414, when the flow that described setting flow determining step S413 detects is consistent with setting flow, close described supply pipe 12, thus, cut off the supply of resin.
Described unlatching supply pipe step S411 refers to that described flow controller 15 controls described opening and closing device 13, and opens the step of the supply pipe 12 be connected with described resin service tank 11.As described above, described resin opens described supply pipe 12 along with by described opening and closing device 13, and from the free-falling of described resin service tank 11, and move to described injection nozzle 40.
Described flow detection step S412 refers to after described unlatching supply pipe step S411, detects the flow transferring to injection nozzle 40, and flow detecting signal is applied to the step of described flow controller 15 at described flowmeter 14.Described flowmeter 14 is arranged at the input side of described injection nozzle 40, detects the flow of resin, thus, flow detecting signal is applied to described flow controller 15.
Described setting flow determining step S413 refers to and confirms at described flow controller 15 flow detecting signal that receives from described flowmeter 14, and compares the step of judgement with the flow of setting.At this, described flow controller 15 compares the flow of setting and the flow of detection, and whether consistent and control described opening and closing device 13 according to it.
Described supply pipe cuts off step S414 and refers to that described flow controller 15 is when the flow that described flow determining step S413 sets is consistent with the flow of detection, driven opening/closing device 13 and close the step of described supply pipe 12.Described flow controller 15 receives the flow detecting signal of described flowmeter 14, judges that the flow detected is consistent with the flow of setting or when exceeding, controls described opening and closing device 13.Described opening and closing device 13, by the control of described flow controller 15, is closed from the supply pipe 12 between described resin service tank 11 to vent valve 30, cuts off the supply of resin.
Therefore, the amount set by described injection nozzle 40 can be injected into transparent display screen by the present invention, thereby, it is possible to prevent the waste caused because of excessive resin by injection.
Described curing schedule S50 refers to after described resin injection step S40, the transparent display screen being bonded with the 1st transparent panel 51 and the 2nd transparent panel 52 is contained in solidification equipment (such as in setting-up time, UV solidification equipment), solidify more than 30 minutes at normal temperatures, and complete the step of resin bed 53.
The present invention can not produce bubble because supplying resin according to free-falling mode described above.It can be confirmed by the sample photo shown in Figure 10.
Fig. 9 is the photo taken existing transparent display screen, and Figure 10 is the photo showing transparent display screen of the present invention.
The resin being contained in resin service tank 11, for as shown in current being suitable for, being transmitted resin by driving fixed displacement pump, and transfers to the 1st transparent panel 51 and the sample photo manufactured by the 2nd transparent panel 52 by Fig. 9 artificially.As shown in the figure, observed and there is multiple bubble B at resin bed 53.
Figure 10 is for the non-artificial generation transmission pressure in free-falling mode, and the photo captured by transparent display screen supplying resin by the free-falling mode produced because of gravity and manufacture.
As shown in the figure, do not observe and there is bubble at the resin bed 53 of transparent display screen.
Thus, the present invention, because being transmitted and resin by injection by free-falling mode, is confirmed and can prevent resin from producing bubble.
Therefore, the present invention supplies resin according to free-falling mode, compared with existing structure, can omit fixed displacement pump, thereby, it is possible to reduce manufacturing cost, not gassing, thus can prevent from forming bad product.
