Field of the Invention The present invention generally relates to a method of setting a coating condition of a coater and a coater using the same, and more particularly to a coating machine for setting a coater. The method of the condition and the coater using the method are capable of forming a sealant pattern having an entirely uniform line width and a completely uniform cross-sectional area. [Prior Art] A liquid crystal display (LCD) is a type of flat panel display device that provides data signals based on image information to individual liquid crystal cells arranged in an array form, and then controls optical transparency of the liquid crystal cells. (optical transparency), while displaying the desired image. The liquid crystal display includes a liquid crystal layer disposed between a thin film transistor (hereinafter referred to as "TFT") substrate having a plurality of pixel patterns and a color filter layer substrate having a color filter layer, and When using a signal, decide whether to transmit light. Further, the TFT substrate and the color filter layer substrate are sealed by a sealant provided on the outer tape. That is, the sealant pattern is formed by applying a sealant to either the TFT substrate or the color filter layer substrate. Coating machine for sealant application process 0 The coater typically includes a stage for supporting the substrate, and a coating head each having a nozzle for discharging the sealant to the substrate Dispensing head Lmit, head support configured to allow the coating head unit to be mounted, and a frame for supporting the platform, the coating head unit, and the 201138982 and the head support ( Frame). The coater is used to apply a sealant to the substrate when changing the relative positions of the substrate and the nozzle. That is, the 'platform and/or head support is horizontally moved in one direction by an actuator, and the coating head unit is horizontally moved by the other actuators to move with the platform and/or the head support. Vertical direction. Therefore, the mouth can be moved relative to the substrate. 'The earthen factory 巫 · · 平 平 平 平 平 平··········································· Figure 1 is a plan view of a sealant pattern formed on a substrate, and Figure 2 is a schematic view of a corner portion of a sealant pattern (C〇mer P〇rti〇n). In general, the flat panel display device includes a rectangular substrate s, and thus the sealant pattern 1 has the shape shown in Fig. 1. s Referring to Fig. 1 'Sealant_1' is formed on the outer tape of the substrate s and has a shape surrounding the central portion of the substrate S. Here, the sealant pattern i includes a straight line portion llne_iGn) 2 parallel to each side of the substrate s, and a curved corner p0rti〇n 3 between the straight portions 2. - 1 line part 2 is # platform or head material moving in the coated shaft or γ axis direction) and the coating head unit is called or head L 2 t other direction (for example γ axis or x axis direction) and the platform nozzle The sealant is discharged to the substrate s. The (4) part 3 of the platform or the head joint _# 1 is the #coating head unit should be formed as a piece of material - the sealing agent is discharged from the nozzle to the substrate S when moving, for example, 'refer to Fig. 2 (square; position Α), The platform 201138982 or the head support that is formed to form the sealant pattern 移动 when moving at the start of the coating of the curved portion 3 is started to decelerate. Further, at the start of application of the S-curved corner portion 3 (at the position a), the coating head unit which forms the sealant pattern in the X-axis direction starts to accelerate. Then, when the application of the curved corner portion 3 is terminated (at the position b), the material or the head support of the case 1 is stopped when moving in the case of 丫 (4), and the sealant pattern is formed in the X-axis direction. The coating head unit stops accelerating and starts moving at the same speed as the coating speed at which the straight portion 2 is formed. Further, it is important that the β sealant pattern 1 has a completely uniform line width and a completely uniform cross section. The above procedure for applying the sealant to the corner portion 3 is problematic in that it is difficult to control the stage, or the head support and the coating head unit to form the sealant pattern i having a uniform line width and a uniform cross-sectional area at the time of deceleration or acceleration. Further, in general, the line width and the cross-sectional area of the sealant pattern 1 are controlled by parameters including a sealant application speed and a sealant application pressure. However, the theoretical value of the coating speed and the coating pressure is different from the measured value due to the delay of the control signal or the like when the sealant is actually applied. Therefore, 'the problem arises because the coating speed curve (applicati〇n Spee (j profiie) does not match the application pressure profile (n〇t consistent)' occurs because the line of the sealant pattern 1 is not precisely controlled. The present invention is directed to a method for setting a coating condition of a coater and a coater using the same, The entire straight portion and the corner portion 201138982 of the sealant pattern can form a sealant pattern having a uniform line width and a uniform cross-sectional area. Another object of the present invention is to provide a method of setting a coating condition of a coater and a coating using the same The cloth machine can accurately control the sealant pattern by making the sealant coating speed curve and the actual measured value of the coating pressure curve coincide with the theoretical value. To achieve the above object, the present invention provides a setting coater A method of coating conditions, the coater has a spray command to dispense a paste using a coating pressure, and the coater is directed to a straight portion Uniform coating speed coating glue and coating the corner portion with a coating speed of a decelerating section and an acceleration section, the method comprising obtaining a coating The speed profile, the measured coating pressure curve, and the coating pressure curve are consistent with the coating speed profile. The coating pressure curve can include a uniform coating pressure for the straight portion and a decompression section for the corner portion. And a coating pressure of the pressurization section. The coating speed curve may include a point at which the deceleration section starts and a point at which the acceleration section terminates; the coating pressure curve may include a point at which the decompression section starts and pressurization a point at which the segment terminates; and the method further includes resetting the coating pressure such that the distance from the point at which the decompression section of the coating pressure curve begins is coincident with the distance from the point at which the deceleration section of the coating speed curve begins And resetting the coating pressure' such that the distance to the point at which the pressurizing section of the coating pressure curve terminates and the point at which the acceleration section of the coating speed curve terminates The distance may be the same. The method may include resetting the coating pressure such that the distance to a particular point of the decompression section of the coating pressure curve coincides with the distance to a particular point of the deceleration section of the coating speed profile: and resetting The pressure is applied such that the distance to a particular point of the pressurized section of the coating pressure curve coincides with the distance to a particular point of the 201138982 acceleration section of the coating speed profile. The coating speed profile can include the beginning of the deceleration section. a point and a point at which the acceleration section terminates; the coating pressure curve may include a point at which the reduced pressure section begins and a point at which the pressurized section terminates; and the method may further include resetting the coating pressure to cause a coating pressure curve The time at which the decompression section starts is coincident with the time at which the deceleration section of the coating speed curve starts; and the time at which the coating pressure is reset, and the point at which the pressing section of the coating pressure curve is terminated is The time at which the acceleration section of the coating speed curve terminates coincides. The method may further comprise resetting the coating pressure such that the time of the specific point of the depressurization section of the coating pressure curve coincides with the time of the specific point of the deceleration section of the coating speed profile; and resetting the coating pressure, The time to a particular point of the pressurization section of the coating pressure curve coincides with the time to a particular point of the acceleration section of the coating speed profile. The specific points in the deceleration section and the acceleration section of the coating speed curve or the decompression section of the coating pressure curve and the specific points in the pressing section may be set to be the lowest speed or pressure ratio The speed or minimum pressure is also 10% higher. The specific points may each comprise a plurality of specific points. Obtaining the coating pressure curve can include obtaining an actual measurement curve of the coating pressure by performing a dummy discharge using a pressure sensor. The coating speed and coating pressure for the corner portion can be set such that the applied glue has the same width and wearing area as the glue applied at the coating speed and coating pressure for the straight portion. The coating speed curve having the decelerating section and the accelerating section for the corner portion has a parabolic shape 'and has a decompression section for the corner portion and the coating pressure curve of the pressurized 201138982 section may have a parabolic shape. Further, in order to achieve the above object, the present invention provides a coater for applying a coating for a coating speed and a coating pressure set by a method of setting a coating condition of a coater.

The cloth speed profile is a combination of a change in the speed Vx of the coating head unit 14 and a change in the speed Vy of the platform 12 or head support 13. Referring first to the coating speed versus distance (or time) curve, the linear portion 41 of the glue pattern 45 is uniformly applied at a coating speed VI. When the point L1 is reached, the coating speed is linearly reduced. Thereafter, when the point L2 is reached, the corner portion 42 is uniformly applied at the coating speed V2. The coating speed is increased from the point L3 to the point L4, and then the coating of the straight portion 41 is uniformly performed at the coating speed VI. Similar to the curve of the coating speed versus the distance (or time), with reference to the curve of the coating pressure versus the distance (or time), the coating is uniformly performed with the coating pressure P1 for the straight portion 41 of the rubber pattern 45. When the point L1 is reached, the coating pressure is linearly reduced. Thereafter, when the point L2 is reached, the corner portion 42 is uniformly applied at the coating pressure P2. The coating pressure is increased from the point L3 to the point L4, and then the coating of the straight portion 41 is uniformly performed at the coating pressure P1. In Figs. 6 to 8, the points LI, L2, L3, and L4 are exemplified as the point at which the coating head unit 开始4 starts to decelerate, the point at which the curved portion of the corner portion 42 starts, and the curved portion of the corner portion 42. The point of termination, and the point at which platform 201138982 12 or head support 13 stops accelerating. 1 , by controlling the coating head unit 14 and the flat head 12 or the head support L, L2, L3, and Μ, respectively, the corner portion 2, the curved portion, the beginning of the 'point, the corner portion 42 in the deceleration section A special point, a specific point in the acceleration section of the corner portion 42, and a point at which the curved portion of the corner portion 42 terminates. U is controlled by the coating head unit 14 and the flat 12 or the head support. And U, U, U, and Μ can be set as the rubber pattern. Figure 9 is (4) Actual measurement of the (10) speed and coating pressure curve. The curve of the coating pressure versus time is parabolic. The pressure value curve of the cloth does not match. It can be seen from Fig. 9 that the 'interval amount _ coating speed curve and the actual measurement of the coating force letter rffe green · · Τ 4α 々々 coating speed on the _ curve can be borrowed (four) The movement of the Lantern, the platform 12, or the head support 13 is measured. Alternatively, the coating speed versus time curve can be a plot of the theoretical coating speed value of Figure 8, rather than the actual measured value (d). (4) Inverse; the reason is that there is no significant difference between the actual measured value of the coating speed versus time curve and the theoretical value, so there is no significant error between the money and the shop. Furthermore, the curve of the coating duty versus time is the amount of pressure _ pressure measured by the dust force sensing H 37 (phase 5) using the test discharge. The pressure value measured by the pressure sensor 37 is not the theoretical value determined as the set value; the reason is not caused by factors such as the delay of the input signal transfer, the residual glue, and the size of the syringe 24, etc., so that the actual measurement is made. Curve change 14 201138982 0 Figure 10 is a graph showing the t-time curve of the method of conforming the coating to the distance (or time) curve and the coating speed not like the theoretical value of Figure 8, g贞( In the curve of the time value, 丄a=quantity r coating_major separation (or time C and e do not match (refer to Figure 9). Line width and cross-sectional area of the cloth speed, showing the actual measurement time The curve of the value needs to match the curve showing the actual measured coating pressure versus distance (or time). D b Therefore the coating speed versus the point (or time) in the distance (or time) curve, A, Β, c, and E 'needs and the coating pressure match the points &, :, d, and e in the distance (or time) curve. For this purpose, based on the coating speed versus distance (or time) curve, the cloth pressure versus distance (or Time) curve matches. That is, in order to make points a, b, c, d, and £ respectively a, b, c, d, and e match, reset the predetermined coating pressure conditions. If the set coating pressure conditions, points A, B, c, D, and E are respectively associated with points a, b, c, d, and e match, and if the sealant is applied by the matching coating conditions (ie, coating speed and coating pressure), a sealant pattern having a uniform line width and a uniform cross-sectional area can be formed. The X-axis of the graph represents the distance (or time). First, the case where the X-axis is the distance (that is, the coating distance of the sealant pattern) is selected as an example. The point B in the coating speed versus distance curve indicates the start of deceleration. Deceleration stiirling distance, and the point b in the coating pressure versus distance curve is expressed as the decompression start distance (decompressi〇n startm, 201138982 distance). Furthermore, the point E in the coating speed versus distance curve indicates The acceleration determination distance ' and the point e in the coating pressure versus distance curve are expressed as the pressurization termination distance. The deceleration starts by moving the point b to the position of the point B. Consistent distance from the start reduced pressure, and by moving the position of the point e to point E of the acceleration of the phase matches the distance from the pressurizing terminated.
一般拋物線形狀形成於塗佈速度對距離曲線的點B及E 之間，且一般拋物線形狀也形成於塗佈壓力對距離曲線的點 b及e之間。 再者，藉由在塗佈速度對距離曲線的點B及E之間以 及在塗佈壓力對距離曲線的點b及e之間加入許多特定點， 可使塗佈速度曲線與塗佈壓力對距離曲線更精確地相符。 舉例而言’在塗佈速度設定為0%(即速度：〇)到1〇〇%(即 速度：直線部分的速度VI)的範圍案例中，可將塗佈速度比 最低點高約10%的兩點設為特定點。 再者，在塗佈壓力設定為0%(即壓力：〇)到1〇〇%(即壓 力.直線部分的壓力P1)的範圍案例中，可將塗佈壓力比最 低點高約10%的兩點設為特定點。 假6又特疋點為在塗佈速度對距離曲線中的點c及d以 及在塗佈壓力對距離曲線中的點c及d，藉由移動點c及d 到點C及D的位置，而使距離彼此相符。 若需要更精確地控制膠圖案的線寬及截面積，可在點B 及e之間及點b及e之間另外加入特定點。隨著加入的特定 點數目的增加，可更精確地控制膠圖案的線寬及戴面積。 201138982 再者，塗佈速度曲線具有最高速度對最低速度的比例， 且重新設定塗佈壓力使得塗佈壓力曲線中最高壓力對最低 壓力的比例與塗佈速度曲線中最高速度對最低速度的比例 相符。 再者，於X軸表示時間（亦即塗佈密封劑圖案所花費的 時間）的範例中，在塗佈速度對時間曲線中的點B表示減速 開始時間(deceleration starting time) ’而在塗佈壓力對時間曲 線中的點b表示為減壓開始時間（dec〇mpressi〇n starhng time)。 再者，在塗佈速度對時間曲線中的點E表示加速終止時 間(acceleration termination time)，而在塗佈壓力對距離曲線 中的點e表示為加壓終止時間（pressurizati〇n terminati〇n time)。 即使在X軸表示時間的案例中，可使塗佈速度曲線與 塗佈壓力曲線相符，如X軸表示距離的案例一般。 如上所述，可使實際量測的塗佈壓力值曲線與實際量測 的塗佈速度值曲線相符，而這些相符的值可輸入做為塗佈機 的設定值，藉此形成膠圖案45的直線部分41及角落部分 42。 於此案例中，可解決因為控制訊號延遲，造成塗佈速度 及塗佈壓力之理論值與實際量測值間的差異而使膠圖案45 變形的問題。此外，能精確地控制膠圖案45。 如上所述，根據本發明設定塗佈機之塗佈條件的方法以 及利用此方法的塗佈機的優點在於，可形成在整個密封劑圖 案具有一致線寬及一致戴面積的密封劑圖案。 本#明的優點在於，即使因為平台或頭支樓件以及塗佈 201138982 頭單70的減速或加速(尤其在形成密封劑圖案的角落部分時) 而V致改4塗佈速度’藉由基於塗饰速度改變塗_壓力，可 形成具有一致線寬及一致截面積的密封劑圖案。 曰再者’本發明的優點在於使密封劑塗佈速度曲線的實際 里測值與塗佈壓力曲線的實㉟量測值相符，而可解決由於塗 佈速度及壓力之理論值與實際量測之間的差異造成密封劑 圖案形狀變形的問題’以及可精確地控制密封劑圖案。 雖然已針龍明目的揭露本發雜佳實施例，但是熟此 技藝者應知在不悖離如所㈣請專利範_揭示的本發明 精神及料下’可有各種的修改、添加、以及替換。 【圖式簡單說明】 本發明㈣及其他的目的、舰、以及優點，結合伴隨 圖式與詳細說明將更清晰，其中： 圖1為形成祕板上之密封細案範例之平面圖； 圖2為顯示密封劑圖案上的位置之圖式； 圖3為應用根據本發g月實施例設定塗佈條件之方法的 塗佈機範例之透視圖； 圖4為圖3所示之塗佈頭單元之透視圖； 圖5為用於塗膠之氣壓供應裝置範例之方塊圖； 圖6為塗佈頭單元之速度Vx變化與平台或頭支樓件之 速度Vy變化之圖式； 圖7為膠圖案之塗佈位置或塗佈時間之圖式； 圖8為基於理論值顯示塗佈速度變化及塗佈壓力變化 之圖式； 圖）為蝻示金佈速度及塗佈壓力曲線之實際量測值的 201138982 圖式；以及 圖為顯示使塗佈壓力對距離(或時間）曲線與塗佈速 度對距離(或時間）曲線相同(identical)之方法的圖式。 【主要元件符號說明】 2直線部分 10塗佈機 12平台 14塗佈頭單元 16導軌 21垂直轉移機構 23位移感測器 3〇氣壓供應裝置 32負壓空氣供應源 34負壓自動調節器 36負壓閥 38控制單元 42角落部分 A、B位置 L2角落部分開始的點 L4直線部分的點 S基板 Vx塗佈頭單元之速度 1密封劑圖案 3曲形角落部分 11框架 13頭支撐件 15導引機構 17導塊 22噴嘴 24注射器 31正壓空氣供應源 33正壓自動調節器 35正壓閥 37壓力感測器 41直線部分 45膠圖案 L1直線部分的點 L3角洛部分終止的點 PI、P2塗佈壓力 VI塗佈速度 vy平台或頭支撐件之速度A generally parabolic shape is formed between points B and E of the coating speed versus distance curve, and a generally parabolic shape is also formed between points b and e of the coating pressure versus distance curve. Furthermore, by applying a number of specific points between the coating speed versus the point B and E of the distance curve and between the coating pressure and the distance point b and e, the coating speed curve and the coating pressure can be applied. The distance curve matches more precisely. For example, in the case where the coating speed is set to 0% (ie, speed: 〇) to 1% (ie, speed: speed VI of the straight portion), the coating speed can be about 10% higher than the lowest point. The two points are set to specific points. Further, in the case where the coating pressure is set to 0% (i.e., pressure: 〇) to 1% by weight (i.e., the pressure P1 in the straight portion), the coating pressure can be increased by about 10% from the lowest point. Two points are set to specific points. False 6 is also characterized by the points c and d in the coating speed versus distance curve and the points c and d in the coating pressure versus distance curve, by moving the points c and d to the positions of points C and D, And make the distances match each other. If you need to control the line width and cross-sectional area of the glue pattern more precisely, you can add a specific point between points B and e and between points b and e. As the number of specific points added increases, the line width and wearing area of the glue pattern can be more precisely controlled. 201138982 Furthermore, the coating speed curve has the ratio of the highest speed to the lowest speed, and the coating pressure is reset so that the ratio of the highest pressure to the lowest pressure in the coating pressure curve matches the ratio of the highest speed to the lowest speed in the coating speed curve. . Further, in the example in which the X-axis represents time (that is, the time taken to apply the sealant pattern), the point B in the coating speed versus time curve indicates the deceleration starting time ' while coating The point b in the pressure versus time curve is expressed as the decompression start time (dec〇mpressi〇n starhng time). Furthermore, the point E in the coating speed versus time curve indicates the acceleration termination time, and the point e in the coating pressure versus distance curve is expressed as the pressurization termination time (pressurizati〇n terminati〇n time). ). Even in the case where the X-axis represents time, the coating speed curve can be made to match the coating pressure curve, as in the case where the X-axis represents the distance. As described above, the actual measured coating pressure value curve can be matched with the actually measured coating speed value curve, and these matching values can be input as the set value of the coater, thereby forming the rubber pattern 45. Straight line portion 41 and corner portion 42. In this case, the problem that the rubber pattern 45 is deformed due to the difference between the theoretical value of the coating speed and the coating pressure and the actual measured value due to the delay of the control signal can be solved. In addition, the glue pattern 45 can be precisely controlled. As described above, the method of setting the coating conditions of the coater according to the present invention and the coater using the method have an advantage in that a sealant pattern having a uniform line width and a uniform wearing area can be formed throughout the sealant pattern. The advantage of this is that even if the platform or head support and the coating of the 201138982 head 70 are decelerated or accelerated (especially when forming the corner portion of the sealant pattern), the V-change 4 coating speed is based on The coating speed changes the coating pressure to form a sealant pattern having a uniform line width and a uniform cross-sectional area.曰 者 者 'The advantage of the present invention is that the actual measured value of the sealant coating speed curve is consistent with the actual 35 measured value of the coating pressure curve, and the theoretical and actual measurement due to the coating speed and pressure can be solved. The difference between them causes a problem that the shape of the sealant pattern is deformed' and the sealant pattern can be precisely controlled. Although the present invention has been disclosed in the context of the present invention, it should be understood that those skilled in the art will be able to make various modifications, additions, and additions as well as the spirit and scope of the present invention disclosed in the patent application. replace.
