On the 9th, although only a slight distance Δ X, Δ Y, the offset of the extremely small distance Δ X, Δ Y on the surface of the substrate 9 , because there is no gap, the measurement from the distance meter 16 The result is almost non-existent with the end of the nozzle 13 a until the surface of the substrate 28 (the upper surface) is separated by a distance of -9 - 1252134 (6). Therefore, based on the measurement result of the distance meter 16, the Z-axis servo motor 12 can be controlled to fit the unevenness (wave shape) on the surface of the substrate, and it can be maintained from the end of the nozzle 13 a to the surface of the substrate 9 ( The distance above. In this way, the distance (interval) from the end of the nozzle 13 a to the surface (upper surface) of the substrate 9 can be maintained constant, and the unit time ejected from the nozzle 13 a is maintained by the quantitative amount. The amount of the paste is such that the width or thickness of the paste pattern drawn on the substrate 9 is the same. Next, a control method relating to the present embodiment will be described. Fig. 4 is a block diagram showing the structure of the control unit of Fig. 2; The main control unit 17, the microcomputer 17a, the motor controller 17b, the external interface I7d, and the image recognition device 17e are connected to the data communication busbar 17c, and further connected to the motor controller 17b, and connected to the X-axis driving device 17f, Y-axis drive. Each of the device 17g, the 0-axis driving device 17h, and the Z-axis driving device 17i, and the respective axis driving devices of γ, Ζ, 0 are connected to the respective driving motors. For example, the 0-axis drive unit 17h is connected to the 0-axis servo motor 8a. In the portion corresponding to the plane of Fig. 1, the ancestral symbol is paid. At the same time, Fig. 1 also has a camera 26 for measuring the inner circumference (inside area) of the electric paste pattern not shown. In the same figure, the active control unit 17 is built with the microcomputer 17a or the motor controller 17b, the X, Y, Z, 0 axis drive devices 17f to 17i, and the image recognition camera 15 Image signal processing device 1 7e, signal transmission between sub-control unit 1 8 or management computer 102 (not shown), or adjustment of regulators 22a, 23a' and valve unit 24 and distance meter 1 6 input external interface 1 7d. -10- 1252134 (7) In addition, the microcomputer 17 7a includes a main calculation unit or a ROM that stores a processing program for performing coating drawing described later, and a processing result stored in the main calculation unit or externally. The interface 1 7d and the RAM of the input data of the motor controller 17b, and the access external interface 17d or the motor controller 17b and the output of the data. The encoders for detecting the amount of rotation are built in the servo motors 4, 6, 8a, and 1 2, and the results are returned to the respective axis drive devices 17f to 17i of X, Y, Z, and 0 to perform position control. The servo motors 4, 6, 8a, and 12 are forward-reversed based on the data received from the keyboard 20 and received in the RAM of the microcomputer 17a. Thereby, the substrate 13 held by the substrate holding mechanism 7 (FIG. 2) and the nozzle 13a (FIG. 3) provided to the electric paste housing tube 13 attached to the Z-axis moving stage 11 (FIG. 2) can be X and Y. Move the axis direction any distance. During the movement of the substrate 9, a small amount of air pressure is continuously applied to the electric paste housing tube 13, and the electric paste is discharged from the discharge port of the tip end portion of the nozzle 13a, and the desired electric paste is applied to the substrate 9. The distance between the nozzle 13a and the substrate 9 is measured by the distance meter 14 in the horizontal movement of the substrate 9 held by the substrate holding mechanism 7 in the X and Y directions. The microcomputer 1 7 a is based on the measurement result, and in order to maintain the nozzle 1 3 a and the substrate at a certain interval, the control command is transmitted to the Z-axis driving device 1 7 i that controls the servo motor 12 . Further, in the present embodiment, although the Z-axis moving platform is only moved in the Z direction, the z-axis moving platform supporting tray 10 may be moved in the X-axis direction as the upper portion of the Z-axis platform supporting frame 2. Further, the Z-axis platform support frame 2 is moved to the γ-axis direction -11 - 1252134

於基板上執行進行塗布描繪之密封圖案之吐出條件,修正 -12- 1252134 (9) 値之計算。 於此,係將修正項目之密封塗布寬度,密封 ,塗布位置之修正(四角形密封內側尺寸修正) 加以說明。此種情況,塡充於面板之液晶量,於 中爲一定。 如圖6所示,當於】片基板上形成複數面板 描繪封閉於面板顯示領域外圍之四角形之密封圖 封圖案之塗布剖面積和塗布位置將能決定塡充液 容積。 換言之,如圖7所示,於基板上之密封圖案 繪位置之中,塗布後之形狀(H。、WQ)爲重疊 藉由進行貼合處理後之形狀爲(H 1、W1 )藉此 空間乃爲塡充液晶之空間。因此’爲了液晶塡充 定,做爲密封圖案之塗布裝置及塗布形狀,有必 高度,寬度(塗布量)因應於彩色濾光片等之形 進行加以修正。 圖9爲表示面板貼何時之狀態和彩色濾光片 圖。如圖9所示。於本實施形態上’於上基板 彩色濾光片5 3和配向膜5

藉由變更後段工程之製造條件,使得吸收前述製造誤差。 於本實施例子上,變更(修正)於塗布工程之密封劑塗布 量或是塗布圖案,係於吸收誤差。 因此,如以上所述,藉由施加修正之密封圖案之塗布 條件,使得能夠進行電糊圖案之塗布描繪。增加塗布高度 ,係於調整噴嘴高度資料,爲了使對基板之噴嘴頭端位置 動作較爲高,而修正資料,反之,當降低塗布高度時’亦 可修正降低噴嘴高度之方向。 如圖8所示,改變部分塗布寬度而亦可調整容積。當 增寬塗布寬度時,係修正(提高)塗布壓力資料,於加寬 塗布寬度方向進行修正,反之,縮小時,係修正(降低) 塗布壓力資料,而於縮小塗布寬度方向進行修正。 另外,將塗布位置資料於加寬方向藉由修正四角密封 圖案之內側面積,而調整密封圖案之塗布位置,進而加寬 液晶之塡充容積。反之,於縮小內側面積方向修正資料, 係可縮小塡充容積。 若彩色濾光片比設計値之誤差範圍形成較爲厚時,以 設計値之高度與寬度形成密封圖案時,其液晶塡充容積不 變小,當將塡充之液晶量使用如設計値之數値時,將溢出 -14- 1252134 (11) 塡充之液晶而於浪費液晶之同時,藉由密封不良將降低良 率’而影響到局密度之顯示。同時,彩色濾光片之厚度比 設計値之誤差範圍較爲小時,以如設計値之數値塗布密封 圖案時,液晶塡充容積將變大,液晶於面板內不會擴散, 依情況於基板間將產生空間,而無法顯示高精密度之顯示 。因此,如前所述,將修正密封圖案之形成。 當此修正結束時,其次,於基板吸附機構7 (圖2 ) 搭載基板9而使其保持(步驟4 0 0 )。 其次,進行基板預備定位處理(步驟5 00 )。於此處 理上,將以畫像辨識照相機1 5來攝影搭載於基板保持機 構7之基板9之定位用符號,以畫像處理求出定位用符號 之重心位置,而檢測於基板9之0方向之傾斜,因應於此 驅動伺服a (圖4 ),亦修正此0方向之傾斜。 又,電糊收納筒1 3內之剩餘電糊較爲少時,於下個 電糊塗布作業上,於此作業途中爲了不使電糊中斷,故將 電糊收納筒1 3與噴嘴1 3 a同時交換。然而,當交換噴嘴 1 3 a時,有時將會產生位置偏移。因此,於未形成基板9 之電糊圖案處,使用交換之新噴嘴13a而進行十字描繪。 且,以畫像處理求出此十字描繪交點之重心位置,演算出 此重心位置和基板9上之定位用符號之重心位置間之距離 。將求出之距離做爲噴嘴1 3 a之電糊吐出口之偏移位置量 dx、dy,於微電腦17a收納內建之RAM。藉此,結束基 板預備定位處理(步驟5 00 )。噴嘴之偏離位置量dx 、dy,係於此後進行之電糊圖案之塗布描繪之動作時,進 -15- 1252134 (12) 行修正。 其次,進行電糊圖案描繪處理(步驟600 )。於此處 理上,於塗布起始位置上,爲了定位噴嘴13a之吐出口, 故使基板9移動,進行噴嘴位置之比較,調整移動。因此 ,首先,於先前基板預備定位處理(步驟5 00 )先取得, 而所收納於微電腦17a之RAM之噴嘴13a之偏移位置量 dx、dy,進行是否位於圖3所示之噴嘴13a之偏離位置量 之容許範圍△ X、△ Y。若於容許範圍內(△ X ^ dx及△ Y ^ dy )時,既保持原狀。若爲容許範圍外(△ X < dx或 △ Y < dy )時,基於此位置偏移量dx,dy,移動基板9, 而解除噴嘴1 3 a之電糊吐出口與基板9之所期望位置間之 偏移,將噴嘴1 3 a定位於所期望之位置。 其次,於電糊圖案描繪高度設定噴嘴13a之高度。基 於噴嘴之初期移動距離資料,初期移動距離部分降下噴嘴 1 3 a。於持續動作上,藉由距離計1 4來量測基板9表面高 度,確認噴嘴13a頭端是否設定於描繪電糊圖案之高度。 結果,當無法設定於描繪高度時,降下噴嘴1 3 a直到描繪 高度。 實際上,反覆進行上述基板9表面計測和噴嘴1 3 a之 微小距離降低,爲了噴嘴1 3 a頭端成爲塗布描繪電糊圖案 之高度而設定。同時,當未交換電糊收納筒13時’噴嘴 13a之偏移位置量dx、dy亦未紀錄。因此’進入電糊圖 案描繪處理(步騾6 0 0 )之後不久’立刻進行於上述說明 之噴嘴13a之高度設定。 -16- 1252134 (13) 當結束以上之處理時,其次,基於收納於微電腦17a 之RAM之電糊圖案資料,驅動伺服馬達4、6。藉此,噴 嘴1 3 a之電糊吐出口爲對向於基板2 8之狀態,因應於此 電糊圖案資料,基板9於X、Y方向移動之同時,於電糊 收納筒1 3施加微小氣壓,開始從噴嘴1 3 a之電糊吐出口 之電糊之吐出。藉此,開始往基板9之電糊圖案之塗布描 繪。 且,此和如先前所說明,微電腦1 7a係從距離計1 4 輸入噴嘴1 3 a之電糊吐出口和基板9之表面之間隔實際資 料,而測定基板9表面之凹凸,因應於此測定値,藉由驅 動Z軸驅動用之伺服馬達1 2,使得從基板9表面之噴嘴 1 3 a之設定高度能維持一定。 如此,進行電糊圖案之描繪。此動作中,噴嘴1 3 a之 電糊吐出口,係進行判斷是否爲藉由基板9上之上述電糊 圖案資料所決定之描繪圖案之終端,若爲終端時,再返回 於基板表面凹凸之測定處理,反覆上述之塗布描繪。如此 ,電糊圖案形成將持續到描繪圖案之終端。 同時,當到達於此描繪圖案終端時,驅動伺服馬達 1 2而使噴嘴〗3 a升高,結束此電糊圖案描繪工程(步驟 600 ) ° 當結束以上之工程時,其次,進入基板排出處理(步 驟700 ),於此圖2之中,解除基板9之保持,排出於裝 置外。 且,其次,判斷有無塗布之基板,(步驟8 00 ),以 -17- 1252134 (14) 其他相同圖案而具有形成電糊膜之基板時,將從步驟300 反覆,當全部基板結束一連串之處理時,作業將全部結束 (步驟9 0 0 )。 於上述之說明上,雖然係將形成彩色濾光片之基板做 爲例子而加以說明,但是即使有關形成TFT基板,亦可 進行相同之修正。 如以上說明之,若藉由本發明時,於液晶單元組立工 程之中,設置輸入LCD面板之設計,生產資訊之手段,

platform. Next, the operation of the apparatus relating to the present embodiment will be described with reference to FIG. In Fig. 5, first, a power source is inserted (step 1). When the power is plugged in, the initial setting of the coater is performed (step 200). In this initial setting, the servo motors 4, 6, 8a, 1 2 for moving the platforms shown in Fig. 2 are driven. Thereby, the substrate holding mechanism 7 is moved to X, γ, and 0 to be positioned at a specific reference position, and the nozzle 13 3 a (FIG. 3) is in the position where the electric paste discharge port starts to apply the paste (also, The starting point of the electric paste coating is set to a specific origin position. Then, the electric paste pattern data or the substrate position data is set, and the setting of the end position data is discharged. The relevant data is input from the keyboard 20 (Fig. 2), and the input data is stored in the RAM built into the microcomputer 1 7 a (Fig. 4) as described above. When the initial setting project (step 200) ends, the next step is to move to step 00, and the main control unit 17 performs communication between the management computer 1 and the design and production information. Specifically, as shown in FIG. 1 , the panel design information stored in the management computer 102 is, for example, a liquid crystal substrate unit design, a color filter height design information, a spacer height design, and the like. And the inspection result data of the aforementioned design of the manufactured substrate is used as the panel production information 104 data, and the external memory device stored in the control system of the electric paste coating machine is stored in the memory (RAM). . Next, in step 350, the discharge condition of the seal pattern for coating drawing is performed on the substrate from the information of the design flaw and the inspection result, and the calculation of -12-1252134 (9) is corrected. Here, the correction coating width, sealing, and coating position correction (square size correction inside the square seal) of the correction item will be described. In this case, the amount of liquid crystal that is added to the panel is constant in the middle. As shown in Fig. 6, when a plurality of panels are formed on the substrate, the coating sectional area and the coating position of the sealed sealing pattern which is enclosed around the periphery of the panel display area can determine the filling volume. In other words, as shown in FIG. 7, in the position of the seal pattern on the substrate, the shape (H., WQ) after coating is overlapped and the shape after the bonding process is (H1, W1). It is a space for filling the LCD. Therefore, in order to charge the liquid crystal, the coating device and the coating shape of the seal pattern are required to have a high height, and the width (coating amount) is corrected in accordance with the shape of the color filter or the like. Figure 9 is a view showing the state of the panel sticker and the color filter. As shown in Figure 9. In the present embodiment, the upper substrate color filter 53 and the alignment film 52 are formed, and the lower substrate 9 is formed with the alignment film 52 in the fifth substrate, and the sealing pattern PP 1 side dispersion spacer 5 is formed in a ring shape. 5 'Drop a specific amount of liquid crystal 5 6 ° These 9, 5 9, keep the lower substrate holder 50 and the upper substrate in a vacuum, after positioning the upper and lower substrates, 'lower the upper base: 5 1 and fit . The coating degree is an example when the allowable range is available. The dense crystal unit is coated with a substrate, and the volume formed is a magnification of 5.9 in a state of formation, forming a TF 歹 歹 ij, in which the upper and lower substrates are 51, the plate holder-13 - 1252134 (10) However, as shown in the enlarged view of Fig. 9(b), the color filter 53 forms a form having irregularities in the thick direction, and the unevenness is not problematic if it is allowed in the design. However, when the substrate is manufactured, it may exceed the allowable condition. When the excess is exceeded as a defective substrate, the manufacturing yield is greatly reduced. Therefore, when the exceeding tolerance is exceeded, the manufacturing error is absorbed by changing the manufacturing conditions of the latter stage. In the present embodiment, the amount of the sealant applied or the applied pattern of the coating process was changed (corrected) to the absorption error. Therefore, as described above, by applying the modified coating condition of the seal pattern, the coating drawing of the electric paste pattern can be performed. Increasing the coating height is based on adjusting the nozzle height data. In order to make the position of the nozzle tip end of the substrate higher, the data is corrected. Conversely, when the coating height is lowered, the direction of the nozzle height can be corrected. As shown in Fig. 8, the volume can be adjusted by changing the partial coating width. When the coating width is widened, the coating pressure data is corrected (increased), and the coating width direction is corrected, and when it is reduced, the coating pressure data is corrected (reduced), and the coating width direction is corrected. Further, the coating position data is corrected in the widening direction by correcting the inner area of the square sealing pattern, thereby adjusting the coating position of the sealing pattern, thereby widening the filling volume of the liquid crystal. Conversely, if the correction data is corrected in the direction of the inner area, the volume of the charge can be reduced. If the color filter is thicker than the design flaw, when the seal pattern is formed by the height and width of the design, the liquid crystal charge volume does not become small, and when the liquid crystal amount is used, the design is used. When counting several times, it will overflow the -14252134 (11) liquid crystal and waste the liquid crystal, and the yield will be reduced by poor sealing, which will affect the display of local density. At the same time, the thickness of the color filter is smaller than the design flaw. When the seal pattern is applied as the design number, the liquid crystal charge volume will become larger, and the liquid crystal will not diffuse in the panel, depending on the substrate. There will be space between them, and it is impossible to display a high-precision display. Therefore, as described above, the formation of the seal pattern will be corrected. When the correction is completed, the substrate 9 is mounted on the substrate adsorption mechanism 7 (Fig. 2) and held (step 480). Next, a substrate preliminary positioning process (step 5 00) is performed. In this process, the image recognition camera 15 is used to image the positioning symbols of the substrate 9 mounted on the substrate holding mechanism 7, and the position of the center of gravity of the positioning symbol is obtained by image processing, and the tilt of the substrate 9 in the 0 direction is detected. In response to this drive servo a (Fig. 4), the tilt in the 0 direction is also corrected. Moreover, when there is a small amount of residual electric paste in the electric paste storage tube 1 3, in the next electric paste application operation, in order to prevent the electric paste from being interrupted during the operation, the electric paste storage tube 13 and the nozzle 13 are placed. a simultaneous exchange. However, when the nozzle 1 3 a is exchanged, a positional shift sometimes occurs. Therefore, cross-drawing is performed using the new nozzle 13a exchanged at the electric paste pattern in which the substrate 9 is not formed. Further, the position of the center of gravity of the cross drawing intersection is obtained by image processing, and the distance between the position of the center of gravity and the position of the center of gravity of the positioning symbol on the substrate 9 is calculated. The distance obtained is taken as the offset position amount dx, dy of the electric discharge port of the nozzle 13a, and the built-in RAM is stored in the microcomputer 17a. Thereby, the substrate preliminary positioning processing (step 5 00) is ended. The amount of deviation of the nozzles dx and dy is corrected by the coating drawing of the electric paste pattern performed thereafter, and is corrected in -15-1252134 (12). Next, an electric paste pattern drawing process is performed (step 600). Here, in order to position the discharge port of the nozzle 13a at the coating start position, the substrate 9 is moved, the nozzle positions are compared, and the movement is adjusted. Therefore, first, the previous substrate preliminary positioning processing (step 00) is first acquired, and the offset position amounts dx and dy of the nozzles 13a of the RAM stored in the microcomputer 17a are deviated from the nozzle 13a shown in Fig. 3. The allowable range of position amount △ X, △ Y. If it is within the allowable range (Δ X ^ dx and Δ Y ^ dy ), it remains as it is. When it is out of the allowable range (Δ X < dx or Δ Y < dy ), the substrate 9 is moved based on the positional shift amount dx, dy, and the electric discharge port of the nozzle 13 a and the substrate 9 are released. The offset between the desired positions is such that the nozzle 13 a is positioned at the desired position. Next, the height of the nozzle 13a is set in the electric paste pattern. Based on the initial movement distance data of the nozzle, the initial moving distance partially drops the nozzle 1 3 a. In the continuous operation, the surface height of the substrate 9 was measured by the distance meter 14 to confirm whether or not the head end of the nozzle 13a was set at the height of the drawing paste pattern. As a result, when it is not possible to set at the drawing height, the nozzle 13 3a is lowered until the drawing height. Actually, the surface measurement of the substrate 9 and the small distance reduction of the nozzle 13 3 are repeatedly performed, and the tip end of the nozzle 13 3 is set to the height of the application drawing paste pattern. At the same time, when the electric paste accommodating cylinder 13 is not exchanged, the offset position amounts dx and dy of the nozzle 13a are also not recorded. Therefore, the height of the nozzle 13a described above is set immediately after "going into the electric paste pattern drawing process (step 650)." -16- 1252134 (13) When the above processing is completed, the servo motors 4 and 6 are driven based on the paste pattern data stored in the RAM of the microcomputer 17a. Thereby, the electric paste discharge port of the nozzle 13a is in a state of being opposed to the substrate 28. According to the electric paste pattern data, the substrate 9 is moved in the X and Y directions, and the electric paste storage tube 13 is applied minutely. The air pressure starts to be discharged from the electric paste of the electric discharge port of the nozzle 13 a. Thereby, the coating of the paste pattern of the substrate 9 is started. Further, as described above, the microcomputer 17a is configured to measure the unevenness of the surface of the substrate 9 from the distance between the surface of the electric discharge port of the nozzle 13a and the surface of the substrate 9 from the distance meter 14. That is, by setting the servo motor 12 for driving the Z-axis, the set height of the nozzles 13 3 from the surface of the substrate 9 can be maintained constant. In this way, the drawing of the electric paste pattern is performed. In this operation, the electric discharge port of the nozzle 13 a is used to determine whether or not the end of the drawing pattern determined by the electric paste pattern data on the substrate 9 is returned to the surface of the substrate. The measurement process is repeated, and the above-described coating drawing is repeated. As such, the pattern formation will continue until the end of the pattern is drawn. At the same time, when the pattern terminal is reached, the servo motor 12 is driven to raise the nozzle _3 a, and the smear pattern drawing process is ended (step 600) ° when the above project is finished, and then, the substrate discharge processing is entered.
