Fig. 4 illustrates according to the supply of the embodiment of the invention and collects the flow chart of the method for liquid crystal.
As shown in Figure 3 and Figure 4, comprise according to the supply of the embodiment of the invention and the method for collection liquid crystal: liquid crystal supply step, liquid crystal supply stop step, liquid crystal is collected step and determining step.
In the liquid crystal supply step, exert pressure to liquid crystal jar 620, thereby make the liquid crystal that is stored in the liquid crystal jar 620 flow into liquid crystal bottle 530 via pipe fitting 650.
Stop step at liquid crystal supply,, stop via the liquid crystal supply of pipe fitting 650 to liquid crystal bottle 530 when the liquid crystal supply of scheduled volume during to liquid crystal bottle 530.Stop step at liquid crystal supply, stop to exert pressure, and the control module 800 that is arranged on the pipe fitting 650 is closed, stop thus via pipe fitting 650 to liquid crystal bottle 530 supply liquid crystal to liquid crystal jar 620.
Collect step at liquid crystal, the liquid crystal in the pipe fitting 650 is collected in the liquid crystal jar 620.According to the example of the liquid crystal in the pipe fitting 650 being collected in the liquid crystal jar 620, the inside of liquid crystal jar 620 is under the atmospheric pressure conditions, and the control module 800 that will be arranged on the pipe fitting 650 is opened, make pipe fitting 650 be communicated with, allow the liquid crystal in the pipe fitting 650 to flow into liquid crystal jar 620 thus because of the cause of gravity with liquid crystal jar 620.If stop the pressure supply from pressure feeding unit 630 to liquid crystal jar 620, then liquid crystal jar 620 can be got back to atmospheric pressure.Yet in order apace the internal pressure of liquid crystal jar 620 to be reduced to atmospheric pressure, liquid crystal jar 620 can be equipped with dropping valve (not shown) or pressure regulating pump (not shown).
In determining step, after collecting the liquid crystal in the pipe fitting 650 in the liquid crystal jar 620, determine whether any liquid crystal that remains in the pipe fitting 650.Preferably, utilize sensor to detect to retain in the existence of the liquid crystal in the pipe fitting 650.If sensor detects liquid crystal, then can define the liquid crystal that retains in the pipe fitting 650.On the contrary, if sensor does not detect liquid crystal, then can determine not retain in the liquid crystal in the pipe fitting 650.
Preferably, the liquid crystal in the pipe fitting 650 is detected in the position, two places on pipe fitting 650.Place in the position, two places discharges the liquid crystal part to liquid crystal bottle 530, and another place is that liquid crystal is from liquid crystal jar 620 discharge parts.
Hereinafter, with operation and the effect described according to the method for liquid crystal supply device of the present invention and supply and collection liquid crystal.
If the amount of liquid crystal that is held in the liquid crystal bottle 530 drops to predetermined height, then coating head unit 500 is moved to the liquid crystal supply position.
Coating head unit 500 is being moved under the state of liquid crystal supply position, actuator 730 moves forward sliding component 740.Along with sliding component 740 moves forward, with the keeper 750 of sliding component 740 coupling, move forward, thereby pipe fitting 650 is inserted among the injection channel H of end socket 540 of liquid crystal bottle 530 with the pipe fitting stay pipe 710 and the pipe fitting 650 of keeper 750 couplings.
When with the liquid crystal supply of scheduled volume during to liquid crystal bottle 530, pressure feeding unit 630 stops to exert pressure to liquid crystal jar 620, and closing control unit 800, stops will to be stored in via pipe fitting 650 liquid crystal supply in the liquid crystal jar 620 thus to liquid crystal bottle 530.
Make the mobile backward sliding component 740 of actuator 730.Along with sliding component 740 moves backward, with the keeper 750 of sliding component 740 couplings, move backward, thereby pipe fitting 650 is removed from the injection channel H of the end socket 540 of liquid crystal bottle 530 with the pipe fitting stay pipe 710 and the pipe fitting 650 of keeper 750 couplings.
Coating head unit 500 is moved to position to substrate dropping liquid crystal drop.
Like this, if the amount of liquid crystal that is arranged in the liquid crystal bottle 530 on the coating head unit 500 drops to predetermined height, then the liquid crystal supply unit with liquid crystal supply to liquid crystal bottle 530.
Simultaneously, if change the kind of the liquid crystal wait to be expelled to substrate, must be with liquid crystal jar 620, pipe fitting 650, control module 800 and other part replacement Cheng Xin.If pipe fitting 650 and control module 800 are separated from one another, then only be replaced with liquid crystal jar 620 and pipe fitting 650 new.
With liquid crystal jar 620, pipe fitting 650, control module 800 and other part replacement Cheng Xin the time, at first, the liquid crystal that remains in the pipe fitting 650 is collected in the liquid crystal jar 620.
According to following method the liquid crystal in the pipe fitting 650 is collected in the liquid crystal jar 620.At first, the inside of liquid crystal jar 620 is communicated with atmosphere, thereby the inside of liquid crystal jar 620 is under the atmospheric pressure.In addition, the control module 800 that is arranged on the pipe fitting 650 is opened, thereby made pipe fitting 650 open.The liquid crystal that in pipe fitting 650, is held since the cause of gravity and via pipe fitting 650 flow downward the time, liquid crystal is collected in the liquid crystal jar 620.
The effect that is arranged on the sensing cell on the pipe fitting 650 is to detect not to be collected into as yet in the liquid crystal jar 620 and still to remain in liquid crystal in the pipe fitting 650.If detected liquid crystal by sensing cell, then the control module to liquid crystal coating sends signal.In the case, can not retubing 650.If there is not liquid crystal to remain in the pipe fitting 650, the pipe fitting 650 that then will be inserted in the pipe fitting stay pipe 710 of liquid crystal injection unit 700 is extracted, thereby pipe fitting 650 is removed from pipe fitting stay pipe 710.Subsequently, new pipe fitting 650 is inserted pipe fitting stay pipe 710.
If the liquid crystal that remains in the pipe fitting 650 is arranged, the liquid crystal that then will remain in the pipe fitting 650 is removed, and will be inserted in the pipe fitting 650 that liquid crystal injects the pipe fitting stay pipe 710 of unit 700 and extract, thereby pipe fitting 650 is removed from pipe fitting stay pipe 710.Subsequently, new pipe fitting is inserted in the pipe fitting stay pipe 710.Can carry out the method for removing liquid crystal from pipe fitting 650 in every way.
According to the present invention, liquid crystal jar 620, pipe fitting 650 and control module 800 are being replaced with when new, liquid crystal in the pipe fitting 650 is collected in the liquid crystal jar 620, determine whether any liquid crystal that remains in the pipe fitting 650, and, if do not have liquid crystal to remain in the pipe fitting 650, then be replaced with liquid crystal jar 620, pipe fitting 650 and control module 800 new.Therefore, liquid crystal jar 620, pipe fitting 650 and control module 800 are being replaced with when new, liquid crystal can not drop to liquid crystal coating, purify canopy, floor or the like.
As mentioned above, the method that the invention provides a kind of liquid crystal supply device and a kind of supply and collect liquid crystal, wherein, with liquid crystal jar, pipe fitting, control module and other part replacement Cheng Xin the time, liquid crystal in the pipe fitting is collected in the liquid crystal jar, determined whether any liquid crystal that remains in the pipe fitting, and, if there is not liquid crystal to remain in the pipe, then with liquid crystal jar, pipe fitting, control module and other part replacement Cheng Xin.Therefore, with liquid crystal jar, pipe, control module and other part replacement Cheng Xin the time, liquid crystal can not drop to liquid crystal coating, purifies canopy, floor or the like.
