液晶塗佈機與液晶供應單元操作如下。The liquid crystal coater and the liquid crystal supply unit operate as follows.
基板放置於液晶塗佈機的平台200上。第一驅動單元及第二驅動單元將塗佈頭單元500從初始位置移到液晶塗佈位置。The substrate is placed on the platform 200 of the liquid crystal coater. The first driving unit and the second driving unit move the coating head unit 500 from an initial position to a liquid crystal coating position.
第一驅動單元及第二驅動單元根據預設資料(preset data)移動塗佈頭單元500。當塗佈頭單元500移動時,透過各塗佈頭單元500的噴嘴551塗佈預定量(predetermined amount)的液晶到基板。基板分成單位面板(unit panel),以及塗佈預定量的液晶到各單位面板。塗佈到個別單位面板的液晶量總和等於塗佈到基板的預定量液晶。The first driving unit and the second driving unit move the coating head unit 500 according to preset data. When the coating head unit 500 moves, a predetermined amount of liquid crystal is applied to the substrate through the nozzles 551 of the respective coating head units 500. The substrate is divided into unit panels, and a predetermined amount of liquid crystal is applied to each unit panel. The sum of the amounts of liquid crystals applied to the individual unit panels is equal to a predetermined amount of liquid crystal applied to the substrate.
在塗佈預定量液晶到基板後,第一驅動單元及第二驅動單元移動塗佈頭單元500到初始位置。After applying a predetermined amount of liquid crystal to the substrate, the first driving unit and the second driving unit move the coating head unit 500 to an initial position.
將安置於平台200的基板更換成新基板。The substrate placed on the platform 200 is replaced with a new one.
放置新基板於平台200後,第一驅動單元及第二驅動單元移動塗佈頭單元500到液晶塗佈位置,以塗佈液晶到基板。After the new substrate is placed on the platform 200, the first driving unit and the second driving unit move the coating head unit 500 to the liquid crystal coating position to apply liquid crystal to the substrate.
第一驅動單元及第二驅動單元根據預設資料移動塗佈頭單元500。當塗佈頭單元500移動時,透過各塗佈頭單元500的噴嘴551塗佈預定量的液晶到基板。The first driving unit and the second driving unit move the coating head unit 500 according to the preset data. When the coating head unit 500 moves, a predetermined amount of liquid crystal is applied to the substrate through the nozzles 551 of the respective coating head units 500.
在塗佈預定量液晶到基板後,塗佈頭單元500移動到初始位置。將放置於平台200的基板更換成新基板。After applying a predetermined amount of liquid crystal to the substrate, the coating head unit 500 is moved to the initial position. The substrate placed on the stage 200 is replaced with a new one.
重複上述程序,而塗佈預定量液晶到複數基板。The above procedure is repeated, and a predetermined amount of liquid crystal is applied to a plurality of substrates.
液晶塗佈機塗佈預定量液晶到各個基板後,量測透過塗佈頭單元500之噴嘴551塗佈的液晶量。一般而言,在塗佈預定量液晶到20或25個基板的各個後,量測透過塗佈頭單元500之噴嘴551塗佈的液晶量。利用安裝於液晶塗佈機的量測單元(measuring unit)110來量測液晶量。在各塗佈頭單元500移到安裝量測單元110的位置後,塗佈頭單元500的噴嘴551塗佈液晶到量測單元110,而量測液晶量。After the liquid crystal coater applies a predetermined amount of liquid crystal to each substrate, the amount of liquid crystal applied through the nozzle 551 of the coating head unit 500 is measured. In general, after applying a predetermined amount of liquid crystal to each of 20 or 25 substrates, the amount of liquid crystal applied through the nozzle 551 of the coating head unit 500 is measured. The amount of liquid crystal is measured by a measuring unit 110 mounted on a liquid crystal coater. After each of the coating head units 500 is moved to the position where the measuring unit 110 is mounted, the nozzles 551 of the coating head unit 500 apply liquid crystal to the measuring unit 110, and the amount of liquid crystal is measured.
若量測單元110所量測的液晶量是在參考範圍內,則塗佈頭單元500移動到液晶塗佈位置,以塗佈液晶到基板。同時,若量測單元110所量測的液晶量不在參考範圍內,則調整流出量,而使得透過塗佈頭單元500之噴嘴551塗佈的液晶量是在參考範圍內,之後將塗佈頭單元500移到液晶塗佈位置。If the amount of liquid crystal measured by the measuring unit 110 is within the reference range, the coating head unit 500 is moved to the liquid crystal coating position to apply liquid crystal to the substrate. Meanwhile, if the amount of liquid crystal measured by the measuring unit 110 is not within the reference range, the outflow amount is adjusted such that the amount of liquid crystal applied through the nozzle 551 of the coating head unit 500 is within the reference range, and then the coating head is applied. Unit 500 is moved to the liquid crystal coating position.
同時,若瓶器530內所含的液晶降到某個程度,提供於液晶塗佈機的顯示單元(display unit)顯示警報。若顯示警報,則停止透過塗佈頭單元500之噴嘴551塗佈液晶於基板的程序。At the same time, if the liquid crystal contained in the bottle 530 is lowered to some extent, the display unit provided to the liquid crystal coater displays an alarm. When an alarm is displayed, the process of applying liquid crystal to the substrate through the nozzle 551 of the coating head unit 500 is stopped.
接著,塗佈頭單元500移到供應液晶的位置。Next, the coating head unit 500 is moved to a position where the liquid crystal is supplied.
當塗佈頭單元500移到液晶供應位置,液晶供應單元供應液晶到塗佈頭單元500的瓶器530。When the coating head unit 500 is moved to the liquid crystal supply position, the liquid crystal supply unit supplies the liquid crystal to the bottle 530 of the coating head unit 500.
液晶供應單元利用以下程序供應液晶到塗佈頭單元500的瓶器530。The liquid crystal supply unit supplies the liquid crystal to the bottle 530 of the coating head unit 500 by the following procedure.
首先,致動器730向前移動滑件740。當滑件740向前移動時,耦接滑件740的支托器750、耦接支托器750的管件支撐管710、以及管件650向前移動,而使管件650***瓶器530之瓶蓋540的注入通道H。First, the actuator 730 moves the slider 740 forward. When the slider 740 moves forward, the holder 750 coupling the slider 740, the tube support tube 710 coupling the holder 750, and the tube 650 move forward, and the tube 650 is inserted into the bottle cap of the bottle 530. Injection channel H of 540.
閥件800打開以及壓力供應單元630供應壓力到液晶槽620內部,而使得儲存於液晶槽620中的液晶流過管件650。藉由供應到液晶槽620內部的壓力,將儲存於液晶槽620中的液晶透過管件650與瓶蓋540的注入通道H供應到瓶器530。The valve member 800 is opened and the pressure supply unit 630 supplies pressure to the inside of the liquid crystal cell 620, so that the liquid crystal stored in the liquid crystal cell 620 flows through the tube member 650. The liquid crystal stored in the liquid crystal cell 620 is supplied to the bottle 530 through the injection passage H of the tube member 650 and the cap 540 by the pressure supplied to the inside of the liquid crystal cell 620.
當供應到瓶器530的液晶達到預定程度,壓力供應單元630停止供應壓力到液晶槽620,閥件800關閉,因而停止將儲存於液晶槽620中的液晶透過管件650供應到瓶器530。When the liquid crystal supplied to the bottle 530 reaches a predetermined level, the pressure supply unit 630 stops the supply pressure to the liquid crystal cell 620, and the valve member 800 is closed, thereby stopping the supply of the liquid crystal through the tube 650 stored in the liquid crystal cell 620 to the bottle 530.
致動器730向後移動滑件740。當滑件740向後移動時,耦接滑件740的支托器750、耦接支托器750的管件支撐管710、以及管件650向後移動,而使管件650從瓶器530之瓶蓋540的注入通道H移出。Actuator 730 moves slider 740 rearward. When the slider 740 moves backward, the holder 750 coupled to the slider 740, the tube support tube 710 coupled to the holder 750, and the tube 650 move backward, and the tube 650 is removed from the cap 540 of the bottle 530. The injection channel H is removed.
已完成將液晶供應到塗佈頭單元500的瓶器530時,塗佈頭單元500移動到液晶塗佈位置。When the liquid crystal is supplied to the bottle 530 of the coating head unit 500, the coating head unit 500 is moved to the liquid crystal coating position.
如此一來,若供應到塗佈頭單元500之瓶器530的液晶量降到某個程度,塗佈頭單元500移到液晶供應位置,使得液晶供應單元供應液晶到塗佈頭單元500。As a result, if the amount of liquid crystal supplied to the bottle 530 of the coating head unit 500 is lowered to some extent, the coating head unit 500 is moved to the liquid crystal supply position, so that the liquid crystal supply unit supplies the liquid crystal to the coating head unit 500.
然而,如上述操作的液晶塗佈機與液晶供應單元具有以下問題。亦即,在塗佈頭單元500之瓶器530內所含的液晶量降到某個程度時,液晶供應單元供應液晶到瓶器530。因此,若在塗佈頭單元500根據預設資料移動並透過塗佈頭單元500之噴嘴551塗佈預定量液晶到基板時,瓶器530內所含的液晶量降到某個程度,則塗佈頭單元500之噴嘴551停止塗佈液晶到基板,然後塗佈頭單元500移到液晶供應位置,而使液晶供應到塗佈頭單元500。因此,由於是在塗佈預定量液晶到基板的途中將液晶供應到瓶器530,因此花費長時間將預定量液晶塗佈到基板。However, the liquid crystal coater and the liquid crystal supply unit which operate as described above have the following problems. That is, when the amount of liquid crystal contained in the bottle 530 of the coating head unit 500 is lowered to some extent, the liquid crystal supply unit supplies the liquid crystal to the bottle 530. Therefore, if the coating head unit 500 moves according to the preset data and applies a predetermined amount of liquid crystal to the substrate through the nozzle 551 of the coating head unit 500, the amount of liquid crystal contained in the bottle 530 is reduced to a certain extent, and then the coating is performed. The nozzle 551 of the cloth head unit 500 stops coating the liquid crystal to the substrate, and then the coating head unit 500 is moved to the liquid crystal supply position, and the liquid crystal is supplied to the coating head unit 500. Therefore, since liquid crystal is supplied to the bottle 530 on the way of applying a predetermined amount of liquid crystal to the substrate, it takes a long time to apply a predetermined amount of liquid crystal to the substrate.
因此,本發明有鑑於先前技術所發生的問題,本發明之一目的在於提供一種供應液晶到液晶塗佈機之方法,其在塗佈液晶到基板的程序期間不需要為了供應液晶而停止塗佈液晶。Accordingly, the present invention has been made in view of the problems occurring in the prior art, and an object of the present invention is to provide a method of supplying liquid crystal to a liquid crystal coater which does not need to stop coating for supplying liquid crystal during a process of applying liquid crystal to a substrate. liquid crystal.

參考圖2、圖3、圖4、以及圖5,說明根據本發明實施例供應液晶到液晶塗佈機的方法。Referring to Figures 2, 3, 4, and 5, a method of supplying a liquid crystal to a liquid crystal coater in accordance with an embodiment of the present invention will be described.
參考圖3,將尚未塗佈液晶的基板S安置於液晶塗佈機的平台200上。第一驅動單元及第二驅動單元將塗佈頭單元500移到液晶塗佈位置。Referring to FIG. 3, the substrate S to which the liquid crystal has not been applied is placed on the stage 200 of the liquid crystal coater. The first driving unit and the second driving unit move the coating head unit 500 to a liquid crystal coating position.
如圖4所示,第一驅動單元及第二驅動單元根據預設資料移動塗佈頭單元500。當塗佈頭單元500沿著預設路徑(preset course)移動時,透過各塗佈頭單元500的噴嘴551塗佈預定量液晶到基板S。基板S分成單位面板A,而塗佈頭單元500塗佈預定量的液晶到各單位面板A。塗佈到個別單位面板A的液晶量總和等於塗佈到基板S的預定量液晶。As shown in FIG. 4, the first driving unit and the second driving unit move the coating head unit 500 according to the preset data. When the coating head unit 500 moves along a preset course, a predetermined amount of liquid crystal is applied to the substrate S through the nozzles 551 of the respective coating head units 500. The substrate S is divided into unit panels A, and the coating head unit 500 applies a predetermined amount of liquid crystal to each unit panel A. The sum of the amounts of liquid crystals applied to the individual unit panels A is equal to a predetermined amount of liquid crystal applied to the substrate S.
在塗佈預定量液晶到基板S後,將圖5所示安置於平台200上的基板S輸送出平台200,以及將圖3所示尚未塗佈液晶的另一個基板S安置於平台200。After coating a predetermined amount of liquid crystal to the substrate S, the substrate S disposed on the stage 200 shown in FIG. 5 is conveyed out of the stage 200, and another substrate S not shown in FIG. 3 to which the liquid crystal is not applied is placed on the stage 200.
詳言之,將基板S更換成另一個基板的操作表示將已塗佈液晶的基板S輸送出平台200,在基板S安置於平台200之前先將尚未塗佈液晶的基板S傳送到平台200。In detail, the operation of replacing the substrate S with another substrate means that the liquid crystal-coated substrate S is conveyed out of the stage 200, and the substrate S to which the liquid crystal has not been applied is transferred to the stage 200 before the substrate S is placed on the stage 200.
針對各個要塗佈液晶的基板S重複這樣的程序。於重複程序的期間,第一驅動單元及第二驅動單元移動塗佈頭單元500到液晶供應位置。液晶供應單元將液晶供應到已移到液晶供應位置的塗佈頭單元500。This procedure is repeated for each substrate S to which a liquid crystal is to be applied. During the repetition of the program, the first driving unit and the second driving unit move the coating head unit 500 to the liquid crystal supply position. The liquid crystal supply unit supplies the liquid crystal to the coating head unit 500 that has moved to the liquid crystal supply position.
在已塗佈預定量液晶到基板S後,在將安置於平台200的基板S更換成新基板S以及將更換的基板S安置於平台200時,或者在量測透過塗佈頭單元500之噴嘴551塗佈的液晶量時,可執行從供應單元供應液晶到塗佈頭單元500的操作。After the predetermined amount of liquid crystal has been applied to the substrate S, when the substrate S disposed on the stage 200 is replaced with the new substrate S and the replaced substrate S is placed on the stage 200, or the nozzle passing through the coating head unit 500 is measured When the amount of liquid crystal applied is 551, an operation of supplying liquid crystal from the supply unit to the coating head unit 500 can be performed.
首先,說明在已塗佈預定量液晶到安置於平台200上的基板S,然後將平台200上的基板S更換成新基板S後,正要將更換的基板S安置於平台200時,各塗佈頭單元500移動到液晶供應位置,使得液晶供應單元將液晶供應到瓶器530的案例。First, after the predetermined amount of liquid crystal has been applied to the substrate S disposed on the stage 200, and then the substrate S on the stage 200 is replaced with the new substrate S, when the replaced substrate S is being placed on the stage 200, each is coated. The cloth head unit 500 is moved to the liquid crystal supply position, so that the liquid crystal supply unit supplies the liquid crystal to the bottle 530.
在已塗佈預定量液晶到安置於平台200上的基板S,然後將已塗佈液晶的基板S更換成另一個基板S後,正要將更換的基板S安置於平台200時,液晶供應單元將液晶供應到各塗佈頭單元500的瓶器530。若供應到塗佈頭單元500之瓶器530的液晶達到預定程度,則終止供應液晶。若在更換的基板S安置於平台200上之時供應到瓶器530的液晶尚未達到預定程度,則可額外供應液晶一段時間直到供應到瓶器530的液晶達到預定程度,或者在更換的基板S安置於平台200上之時可終止液晶的供應。After the predetermined amount of liquid crystal has been applied to the substrate S disposed on the stage 200, and then the liquid crystal-coated substrate S is replaced with another substrate S, the liquid crystal supply unit is being placed when the replaced substrate S is being placed on the stage 200 The liquid crystal is supplied to the bottle 530 of each of the coating head units 500. If the liquid crystal supplied to the bottle 530 of the coating head unit 500 reaches a predetermined level, the supply of the liquid crystal is terminated. If the liquid crystal supplied to the bottle 530 is not yet reached a predetermined level when the replaced substrate S is placed on the stage 200, the liquid crystal may be additionally supplied for a period of time until the liquid crystal supplied to the bottle 530 reaches a predetermined level, or the substrate S is replaced. The supply of the liquid crystal can be terminated when placed on the platform 200.
在中斷及停止供應液晶到各塗佈頭單元500之瓶器530後,第一驅動單元及第二驅動單元移動塗佈頭單元500到液晶塗佈位置。After interrupting and stopping the supply of the liquid crystal to the bottle 530 of each of the coating head units 500, the first driving unit and the second driving unit move the coating head unit 500 to the liquid crystal coating position.
第一驅動單元及第二驅動單元根據預設資料移動塗佈頭單元500。當塗佈頭單元500沿著預設路徑移動時,透過各塗佈頭單元500的噴嘴551塗佈預定量液晶到基板S。在已塗佈預定量液晶到基板S後,將安置於平台200上的基板S更換成另一個基板S,以及將更換的基板S安置於平台200上。於基板S的更換期間,第一驅動單元及第二驅動單元將塗佈頭單元500移到液晶供應單元供應液晶的位置。The first driving unit and the second driving unit move the coating head unit 500 according to the preset data. When the coating head unit 500 moves along the preset path, a predetermined amount of liquid crystal is applied to the substrate S through the nozzles 551 of the respective coating head units 500. After a predetermined amount of liquid crystal has been applied to the substrate S, the substrate S disposed on the stage 200 is replaced with another substrate S, and the replaced substrate S is placed on the stage 200. During the replacement of the substrate S, the first driving unit and the second driving unit move the coating head unit 500 to a position where the liquid crystal supply unit supplies the liquid crystal.
藉由重複上述程序,可塗佈預定量液晶到複數基板的各個,再者可供應液晶到各塗佈頭單元500的瓶器530。By repeating the above procedure, a predetermined amount of liquid crystal can be applied to each of the plurality of substrates, and liquid crystal can be supplied to the bottle 530 of each of the coating head units 500.
同時,將液晶供應到各塗佈頭單元500之瓶器530的時間可由使用者變化地設定。At the same time, the time during which the liquid crystal is supplied to the bottle 530 of each of the coating head units 500 can be variably set by the user.
首先,每次將已塗佈液晶的基板S更換成另一個基板S並安置於平台200上時,可供應液晶到各塗佈頭單元500的瓶器530。亦即,可將液晶供應時間設定成當預定量液晶已塗佈到基板S,而將基板S更換成另一個基板S並安置於平台200時,供應液晶到各塗佈頭單元500。First, each time the liquid crystal-coated substrate S is replaced with another substrate S and placed on the stage 200, the liquid crystal can be supplied to the bottle 530 of each coating head unit 500. That is, the liquid crystal supply time can be set such that when a predetermined amount of liquid crystal has been applied to the substrate S, and the substrate S is replaced with another substrate S and placed on the stage 200, liquid crystal is supplied to each of the coating head units 500.
液晶供應時間也可設定成於重複上述程序期間,在第m次塗佈液晶到安置於平台200上的基板S後,當基板S更換成另一個基板S並安置於平台200上時,供應液晶到各塗佈頭單元500,其中m為使用者預設的特定整數的倍數,例如特定整數為2或3,或可為使用者決定的任何數字(例如3、5、7...)。The liquid crystal supply time may also be set to be during the repeating of the above procedure, after the liquid crystal is applied to the substrate S disposed on the stage 200 at the mth time, and when the substrate S is replaced with another substrate S and placed on the stage 200, the liquid crystal is supplied. To each of the coating head units 500, where m is a multiple of a particular integer preset by the user, such as a particular integer of 2 or 3, or any number (eg, 3, 5, 7...) that may be determined by the user.
若使用者預設的第m次為3的倍數,則例如當第3次、第6次、第9次等等安置於平台200並已塗佈液晶的基板S更換成另一個新基板S並安置於平台200上時,可供應液晶到瓶器530。同時,若正塗佈液晶到安置於平台200不是3的倍數次的基板S(例如第4次或第5次安置於平台200的基板S)時,感測器或類似裝置偵測到瓶器530中所儲存的液晶為預設量或少於預設量時,則較佳是在將相關基板S更換成另一個基板S並安置於平台200時,將液晶供應到瓶器530。If the mth time preset by the user is a multiple of 3, for example, when the third, sixth, ninth, etc., the substrate S that has been coated on the platform 200 and the liquid crystal has been applied is replaced with another new substrate S and When placed on the platform 200, a liquid crystal to bottle 530 can be supplied. Meanwhile, if the liquid crystal is being applied to the substrate S disposed on the stage 200 not multiples of 3 (for example, the substrate S disposed on the platform 200 for the 4th or 5th time), the sensor or the like detects the bottle When the liquid crystal stored in 530 is a preset amount or less than a preset amount, it is preferable to supply the liquid crystal to the bottle 530 when the related substrate S is replaced with another substrate S and placed on the stage 200.
接著,說明在量測透過塗佈頭單元500之噴嘴551塗佈的液晶量時,各塗佈頭單元移到液晶供應位置而使液晶供應單元供應液晶到瓶器530的案例。Next, a case in which the respective coating head units are moved to the liquid crystal supply position and the liquid crystal supply unit supplies the liquid crystal to the bottle 530 when measuring the amount of liquid crystal applied through the nozzles 551 of the coating head unit 500 will be described.
將尚未塗佈液晶的基板S安置於液晶塗佈機的平台200上。如圖6所示,在液晶塗佈機塗佈預定量液晶到基板S後,塗佈頭單元500移到量測單元110上方,以量測透過各塗佈頭單元500之噴嘴551塗佈的液晶量。較佳地,各量測單元110安裝在液晶供應到塗佈頭單元500的位置的下方。利用量測單元110開始量測透過塗佈頭單元500之噴嘴551塗佈的液晶量。當利用量測單元110量測透過塗佈頭單元500之噴嘴551塗佈的液晶量時,液晶供應單元供應液晶到塗佈頭單元500的瓶器530。於此,除了在已塗佈預定量液晶到基板S後量測透過塗佈頭單元500之噴嘴551塗佈的液晶量之操作外,可執行將已塗佈液晶的基板S更換成另一個基板S的操作。The substrate S to which the liquid crystal has not been applied is placed on the stage 200 of the liquid crystal coater. As shown in FIG. 6, after a predetermined amount of liquid crystal is applied to the substrate S by the liquid crystal coater, the coating head unit 500 is moved over the measuring unit 110 to measure the coating through the nozzle 551 of each coating head unit 500. The amount of liquid crystal. Preferably, each of the measuring units 110 is installed below a position where the liquid crystal is supplied to the coating head unit 500. The measurement unit 110 starts measuring the amount of liquid crystal applied through the nozzle 551 of the coating head unit 500. When the amount of liquid crystal applied through the nozzle 551 of the coating head unit 500 is measured by the measuring unit 110, the liquid crystal supply unit supplies the liquid crystal to the bottle 530 of the coating head unit 500. Here, in addition to the operation of measuring the amount of liquid crystal applied through the nozzle 551 of the coating head unit 500 after a predetermined amount of liquid crystal has been applied to the substrate S, the substrate S on which the liquid crystal has been applied may be replaced with another substrate. S operation.
在已量測透過塗佈頭單元500之噴嘴551塗佈的液晶量後,第一驅動單元及第二驅動單元將塗佈頭單元500移到液晶塗佈位置。After the amount of liquid crystal applied through the nozzle 551 of the coating head unit 500 has been measured, the first driving unit and the second driving unit move the coating head unit 500 to the liquid crystal coating position.
第一驅動單元及第二驅動單元根據預設資料移動塗佈頭單元500。當塗佈頭單元500沿著預設路徑移動時,透過各塗佈頭單元500的噴嘴551塗佈預定量液晶到基板S。The first driving unit and the second driving unit move the coating head unit 500 according to the preset data. When the coating head unit 500 moves along the preset path, a predetermined amount of liquid crystal is applied to the substrate S through the nozzles 551 of the respective coating head units 500.
在塗佈預定量液晶到基板S後,第一驅動單元及第二驅動單元將塗佈頭單元500移到量測單元110上方,並且將安置於平台200上的基板S更換成另一個新基板S。After applying a predetermined amount of liquid crystal to the substrate S, the first driving unit and the second driving unit move the coating head unit 500 over the measuring unit 110, and replace the substrate S disposed on the stage 200 with another new substrate. S.
當針對要塗佈液晶的各基板S重複上述程序時,液晶塗佈機塗佈預定量液晶到複數個基板S的各個。於重複程序期間,量測透過塗佈頭單元500之噴嘴551塗佈的液晶量。在量測液晶量時,將液晶供應到塗佈頭單元500的瓶器530。When the above procedure is repeated for each substrate S to which the liquid crystal is to be applied, the liquid crystal coater applies a predetermined amount of liquid crystal to each of the plurality of substrates S. The amount of liquid crystal applied through the nozzle 551 of the coating head unit 500 is measured during the repeating process. When the amount of liquid crystal is measured, the liquid crystal is supplied to the bottle 530 of the coating head unit 500.
同時,量測透過塗佈頭單元500之噴嘴551塗佈的液晶量,以及在量測液晶量時供應液晶到塗佈頭單元500之瓶器530的操作,可在每次已塗佈預定量液晶到基板S後執行,或可僅在已塗佈預定量液晶到使用者預設第m次安置於平台200之基板S後執行。At the same time, the amount of liquid crystal applied through the nozzle 551 of the coating head unit 500, and the operation of supplying the liquid crystal to the bottle 530 of the coating head unit 500 when measuring the amount of liquid crystal, can be applied at a predetermined amount each time. The liquid crystal is performed after the substrate S, or may be performed only after the predetermined amount of liquid crystal has been applied to the substrate S that the user presets to be placed on the platform 200 for the mth time.
即使在已塗佈預定量液晶到不是使用者預設的第m次安置於平台200上的基板S後,如有需要仍可執行量測透過塗佈頭單元500之噴嘴551塗佈的液晶量的操作。於此案例,當量測液晶量時,液晶不會供應到塗佈頭單元500的瓶器530。Even after a predetermined amount of liquid crystal has been applied to the substrate S disposed on the stage 200 that is not preset by the user, the amount of liquid crystal applied through the nozzle 551 of the coating head unit 500 can be measured if necessary. Operation. In this case, liquid crystal is not supplied to the bottle 530 of the coating head unit 500 when the liquid crystal amount is equivalently measured.
同時,若正塗佈液晶到安置於平台200不是使用者預設的第m次的基板S時,感測器或類似裝置偵測到瓶器530中所儲存的液晶為預設量或少於預設量時,則較佳是在已塗佈預定量液晶到相關基板S後,將液晶供應到瓶器530。Meanwhile, if the liquid crystal is being applied to the substrate S disposed on the platform 200 that is not preset by the user, the sensor or the like detects that the liquid crystal stored in the bottle 530 is a preset amount or less. At a predetermined amount, it is preferred to supply the liquid crystal to the bottle 530 after a predetermined amount of liquid crystal has been applied to the relevant substrate S.
在液晶塗佈機塗佈預定量液晶到這些基板後,檢查及維修液晶塗佈機。當檢查及維修液晶塗佈機時,不將基板S供應到正在檢查及維修的液晶塗佈機,而是供應到在下個位置的液晶塗佈機。After a predetermined amount of liquid crystal is applied to the substrates by the liquid crystal coater, the liquid crystal coater is inspected and repaired. When the liquid crystal coater is inspected and repaired, the substrate S is not supplied to the liquid crystal coater under inspection and maintenance, but is supplied to the liquid crystal coater at the next position.
當維修液晶塗佈機時,液晶供應單元可供應液晶到塗佈頭單元500的瓶器530。When the liquid crystal coater is repaired, the liquid crystal supply unit can supply the liquid crystal to the bottle 530 of the coating head unit 500.
在已修復液晶塗佈機後,將基板S安置於平台200上。第一驅動單元及第二驅動單元將塗佈頭單元500移到液晶塗佈位置。After the liquid crystal coater has been repaired, the substrate S is placed on the stage 200. The first driving unit and the second driving unit move the coating head unit 500 to a liquid crystal coating position.
第一驅動單元及第二驅動單元根據預設資料移動塗佈頭單元500。當塗佈頭單元500沿著預設路徑移動時,透過各塗佈頭單元500的噴嘴551塗佈預定量液晶到基板S。The first driving unit and the second driving unit move the coating head unit 500 according to the preset data. When the coating head unit 500 moves along the preset path, a predetermined amount of liquid crystal is applied to the substrate S through the nozzles 551 of the respective coating head units 500.
每當預定量液晶已塗佈到複數基板時,就檢查及維修液晶塗佈機。亦即,可週期性地檢查及維修液晶塗佈機。The liquid crystal coater is inspected and repaired whenever a predetermined amount of liquid crystal has been applied to a plurality of substrates. That is, the liquid crystal coater can be inspected and repaired periodically.
同時,液晶供應單元利用以下程序供應液晶到塗佈頭單元500的瓶器530。At the same time, the liquid crystal supply unit supplies the liquid crystal to the bottle 530 of the coating head unit 500 by the following procedure.

When the slider 740 moves forward, the holder 750 coupling the slider 740, the tube support tube 710 coupling the holder 750, and the tube 650 move forward, and the tube 650 is inserted into the bottle cap of the bottle 530. Injection channel H of 540.
閥件800打開以及壓力供應單元630供應壓力到液晶槽620內部,而使得儲存於液晶槽620中的液晶流過管件650。藉由供應到液晶槽620內部的壓力,將儲存於液晶槽620中的液晶透過管件650與瓶蓋540的注入通道H供應到瓶器530。The valve member 800 is opened and the pressure supply unit 630 supplies pressure to the inside of the liquid crystal cell 620, so that the liquid crystal stored in the liquid crystal cell 620 flows through the tube member 650. The liquid crystal stored in the liquid crystal cell 620 is supplied to the bottle 530 through the injection passage H of the tube member 650 and the cap 540 by the pressure supplied to the inside of the liquid crystal cell 620.
當供應到瓶器530的液晶達到預定程度,壓力供應單元630停止供應壓力到液晶槽620,以及閥件800關閉,因而停止將儲存於液晶槽620中的液晶透過管件650供應到瓶器530。When the liquid crystal supplied to the bottle 530 reaches a predetermined level, the pressure supply unit 630 stops the supply pressure to the liquid crystal cell 620, and the valve member 800 is closed, thereby stopping the supply of the liquid crystal transmission tube 650 stored in the liquid crystal cell 620 to the bottle 530.
致動器730向後移動滑件740。當滑件740向後移動時,耦接滑件740的支托器750、耦接支托器750的管件支撐管710、以及管件650向後移動,而使管件650從瓶器530之瓶蓋540的注入通道H移出。Actuator 730 moves slider 740 rearward. When the slider 740 moves backward, the holder 750 coupled to the slider 740, the tube support tube 710 coupled to the holder 750, and the tube 650 move backward, and the tube 650 is removed from the cap 540 of the bottle 530. The injection channel H is removed.
液晶供應單元的數量可等於或不同於塗佈頭單元500的數量。若液晶供應單元的數量等於塗佈頭單元500的數量,則每當塗佈頭單元500移到液晶供應位置時,各液晶供應單元供應液晶到一個對應的塗佈頭單元500。亦即,一個液晶供應單元供應液晶到一個塗佈頭單元500的瓶器530。The number of liquid crystal supply units may be equal to or different from the number of coating head units 500. If the number of liquid crystal supply units is equal to the number of the coating head units 500, each liquid crystal supply unit supplies liquid crystals to a corresponding coating head unit 500 each time the coating head unit 500 is moved to the liquid crystal supply position. That is, a liquid crystal supply unit supplies liquid crystals to the bottle 530 of a coating head unit 500.
若液晶供應單元的數量小於塗佈頭單元500的數量,則液晶供應單元交替地供應液晶到塗佈頭單元500的個別瓶器530。舉例而言,如圖7所示,假設有6個塗佈頭單元500以及3個液晶供應單元,當塗佈頭單元500移到第一個液晶供應位置時,3個液晶供應單元供應液晶到奇數塗佈頭單元500的瓶器530。接著,如圖8所示,當塗佈頭單元500移到第二個液晶供應位置時,3個液晶供應單元供應液晶到偶數塗佈頭單元500的瓶器530。If the number of liquid crystal supply units is smaller than the number of the coating head units 500, the liquid crystal supply unit alternately supplies the liquid crystals to the individual bottle stoppers 530 of the coating head unit 500. For example, as shown in FIG. 7, assuming that there are six coating head units 500 and three liquid crystal supply units, when the coating head unit 500 is moved to the first liquid crystal supply position, the three liquid crystal supply units supply liquid crystals to The bottle 530 of the odd coating head unit 500 is odd. Next, as shown in FIG. 8, when the coating head unit 500 is moved to the second liquid crystal supply position, the three liquid crystal supply units supply the liquid crystal to the bottle 530 of the even coating head unit 500.
同時,例如是在最終量測透過噴嘴塗佈的液晶量,然後預定量液晶塗佈到基板S重複次數(例如20或25)後,量測透過塗佈頭單元500之噴嘴551塗佈的液晶量。At the same time, for example, after finally measuring the amount of liquid crystal applied through the nozzle, and then applying a predetermined amount of liquid crystal to the substrate S for the number of repetitions (for example, 20 or 25), the liquid crystal applied through the nozzle 551 of the coating head unit 500 is measured. the amount.
若藉由量測單元110量測的液晶量是在參考範圍內,則將塗佈頭單元500移到液晶塗佈位置,以塗佈液晶到基板S。同時,若藉由量測單元110量測的液晶量不在參考範圍內,則調整流出量而使透過塗佈頭單元500之噴嘴551塗佈的液晶量是在參考範圍內,之後將塗佈頭單元500移到液晶塗佈位置。If the amount of liquid crystal measured by the measuring unit 110 is within the reference range, the coating head unit 500 is moved to the liquid crystal coating position to coat the liquid crystal to the substrate S. Meanwhile, if the amount of liquid crystal measured by the measuring unit 110 is out of the reference range, the outflow amount is adjusted so that the amount of liquid crystal applied through the nozzle 551 of the coating head unit 500 is within the reference range, and then the coating head is applied. Unit 500 is moved to the liquid crystal coating position.
當供應到塗佈頭單元500之瓶器530的液晶達到預定程度時,提供於瓶器530的感測器偵測液晶量。控制單元使液晶供應單元停止供應液晶。When the liquid crystal supplied to the bottle 530 of the coating head unit 500 reaches a predetermined level, the sensor provided to the bottle 530 detects the amount of liquid crystal. The control unit causes the liquid crystal supply unit to stop supplying the liquid crystal.
若液晶供應單元之液晶槽620中儲存的液晶降到某個程度時,感測單元執行量測並經由控制單元顯示警報到顯示單元。管理員將液晶槽620更換成新的液晶槽。If the liquid crystal stored in the liquid crystal cell 620 of the liquid crystal supply unit is lowered to some extent, the sensing unit performs measurement and displays an alarm to the display unit via the control unit. The administrator replaces the liquid crystal cell 620 with a new one.
於後,根據本發明供應液晶到液晶塗佈機的效應如下。Thereafter, the effect of supplying liquid crystal to the liquid crystal coater according to the present invention is as follows.
根據本發明,將安置於平台200的基板S更換成新基板S時,塗佈頭單元500移到液晶供應位置,使得從液晶供應單元供應液晶到塗佈頭單元500的瓶器530。According to the present invention, when the substrate S disposed on the stage 200 is replaced with the new substrate S, the coating head unit 500 is moved to the liquid crystal supply position so that the liquid crystal is supplied from the liquid crystal supply unit to the bottle 530 of the coating head unit 500.
根據本發明,每當安置於平台200的基板S更換成新基板S時,就可從液晶供應單元供應液晶到塗佈頭單元500的瓶器530。再者,每當安置在平台之對應預設次數的基板S更換成新基板時,在更換基板S時就可供應液晶。According to the present invention, each time the substrate S disposed on the stage 200 is replaced with a new substrate S, the liquid crystal can be supplied from the liquid crystal supply unit to the bottle 530 of the coating head unit 500. Furthermore, each time the substrate S placed corresponding to the preset number of times of the platform is replaced with a new substrate, the liquid crystal can be supplied when the substrate S is replaced.
根據本發明,當量測透過塗佈頭單元500之噴嘴551塗佈的液晶量時,可從液晶供應單元供應液晶到塗佈頭單元500的瓶器530。According to the present invention, when the amount of liquid crystal applied through the nozzle 551 of the coating head unit 500 is equivalently measured, liquid crystal can be supplied from the liquid crystal supply unit to the bottle 530 of the coating head unit 500.
根據本發明,當檢查及維修液晶塗佈機時,液晶供應單元可供應液晶到塗佈頭單元500的瓶器530。According to the present invention, when the liquid crystal coater is inspected and repaired, the liquid crystal supply unit can supply the liquid crystal to the bottle 530 of the coating head unit 500.
如此一來,根據本發明,將安置於平台200的基板S更換成新基板S時,或者量測透過塗佈頭單元500之噴嘴551塗佈的液晶量時,或者檢查及維修液晶塗佈機時,將液晶供應到塗佈頭單元500的瓶器530。As a result, according to the present invention, when the substrate S placed on the stage 200 is replaced with a new substrate S, or when the amount of liquid crystal applied through the nozzle 551 of the coating head unit 500 is measured, or the liquid crystal coating machine is inspected and repaired At this time, the liquid crystal is supplied to the bottle 530 of the coating head unit 500.
傳統上,若在塗佈預定量液晶到基板S的程序期間耗盡瓶器530的液晶,必須停止塗佈液晶到基板S的程序,而延遲了液晶塗佈程序。Conventionally, if the liquid crystal of the bottle 530 is exhausted during the process of applying a predetermined amount of liquid crystal to the substrate S, the procedure of applying the liquid crystal to the substrate S must be stopped, and the liquid crystal coating process is delayed.
然而,根據本發明,將液晶供應到塗佈頭單元500的瓶器530是在液晶塗佈程序不可避免地停止期間,例如將安置於平台200的基板S更換成新基板S時,或者量測透過塗佈頭單元500之噴嘴551塗佈的液晶量時。因此,瓶器530總是有預定量或更多的液晶,而不會正在塗佈液晶到基板S時為了要供應液晶到瓶器530而停止液晶塗佈程序。However, according to the present invention, the bottle 530 supplying the liquid crystal to the coating head unit 500 is during the inevitable stop of the liquid crystal coating process, for example, when the substrate S disposed on the stage 200 is replaced with a new substrate S, or measurement The amount of liquid crystal applied through the nozzle 551 of the coating head unit 500. Therefore, the bottle 530 always has a predetermined amount or more of liquid crystal, and the liquid crystal coating process is stopped in order to supply the liquid crystal to the bottle 530 when the liquid crystal is applied to the substrate S.
因此,可降低利用液晶塗佈機塗佈預定量液晶到各基板所需的時間。Therefore, the time required to apply a predetermined amount of liquid crystal to each substrate by the liquid crystal coater can be reduced.
如上所述,本發明提供了供應液晶到液晶塗佈機的方法,其在將安置於平台的基板更換成新基板時,或者量測透過塗佈頭單元之噴嘴塗佈的液晶量時,或者檢查及維修液晶塗佈機時,將液晶供應到塗佈頭單元的瓶器。因此,瓶器總是有預定量的液晶,因而避免在透過塗佈頭單元之噴嘴塗佈液晶到基板時為了要供應液晶到瓶器而停止液晶塗佈程序。藉此,降低液晶塗佈機塗佈預定量液晶到各基板所需的時間。As described above, the present invention provides a method of supplying a liquid crystal to a liquid crystal coater, when replacing a substrate disposed on a stage with a new substrate, or measuring a liquid crystal amount applied through a nozzle of the coating head unit, or When inspecting and repairing the liquid crystal coater, the liquid crystal is supplied to the bottle holder of the coating head unit. Therefore, the bottle holder always has a predetermined amount of liquid crystal, thereby avoiding stopping the liquid crystal coating process in order to supply the liquid crystal to the bottle when the liquid crystal is applied to the substrate through the nozzle of the coating head unit. Thereby, the time required for the liquid crystal coater to apply a predetermined amount of liquid crystal to each substrate is reduced.
