Method for coating ’ and used [Prior Art] Glue machine When manufacturing a flat panel display, in order to consume two substrates, the glue is applied to the substrate in a desired pattern. 'Using the coating head of the point: === = ❹ in one direction. Similarly, the coating head differs by: ί straight to the direction of the platform and/or the surface element (four). Therefore, the mouth can be moved against the substrate. The actuation ft is controlled by the control unit to change the relative position of the nozzle = the soil plate based on the information about the pattern of the pattern to be formed on the substrate, thereby forming a glue pattern on the substrate. The glue pattern has, in general, the shape shown in Figure 1 since the flat panel display comprises a square substrate, 6 200932378. As shown in Fig. 1, the glue pattern 1 is formed in a square shape except for the corners of the substrate s. Shaped, and formed a curved shape near the corner of the substrate s to form a linear coating head to form a solid coating head to maintain solidity by moving the platform in the γ-axis direction and moving the coating head and platform together from the nozzle "glue base ===== It is recognized from the nozzle row, and when the slab-turning portion 3 is used, the simple fixed coating 移动 flat movement ^ completely forms the curved portion 3, and the coating head or the platform 2 is stopped. Coating the glue to shorten the coating time. · ' However, if the coating is performed at a high coating speed, when the coating is started to form the curved portion 3, 'the high impact is maintained on the platform that remains fixed. Similarly, 胄When the topographic curved portion 3 is completely coated, the impact on the moving platform is high. Therefore, the platform or the dispenser may vibrate. Due to such vibration, the height, width and straight portion of the curved portion 3 may occur. 2 different problems. This problem may occur even when the head slab unit moves and the platform moves. Especially in the case of handling large substrates, the size and weight of the platform and the head slab unit must be increased, so that The problem is even more serious. For this reason, there is a limit to the coating speed. g 7 200932378 [Summary of the Invention] ί Fayue provides a method of applying glue by using a dispenser to ensure a rubber pattern even when the coating speed is increased or a large substrate is used. The present invention also provides a pneumatic supply device for changing the coating pressure when the coating glue forms a curved portion of the rubber pattern. According to an aspect of the present invention, there is provided a coating machine using a dispensing machine. The method of coating the glue, the dispensing machine coating the knee on the substrate to form a glue pattern having a straight portion and a curved portion] by horizontally moving the coating head including the nozzle with respect to the platform on which the substrate is placed at a coating speed By means of coating pressure, the glue is discharged from the nozzle, and the method comprises: from the starting position of the curve or the preset position from the start position of the curve to the other position before the end of the curve, the coating speed is from the straight line The cloth speed is reduced to the curve coating speed; the acceleration starting position from the end position of the deceleration to the end position of the curve before the end position of the scale is 'maintaining the coating speed as the curve coating speed; from the deceleration starting position to the deceleration end position The coating pressure is reduced from the linear coating pressure to the curve coating pressure; and © from the reduced secret position to the acceleration starting position, the coating is applied to the curve coating pressure. According to another aspect of the present invention, a pneumatic supply is provided. And a device for performing the coating method according to any one of claims 1 to 13, and applying a coating pressure to the syringe containing the glue to discharge the glue from the nozzle connected to the syringe, the pneumatic The supply device includes a positive pressure automatic regulator, receives positive pressure air, adjusts the pressure of positive pressure air, and supplies positive pressure air with adjusted pressure to the injector; 200932378 negative pressure automatic regulator receives negative pressure air 'adjusts negative pressure air The pressure, as well as the supply of negative pressure air to the syringe; and the pressure detector, measuring the air pressure 'where the positive pressure air supplied by the positive pressure automatic regulator and the negative pressure automatic regulator supply Pressurized air mixing' where the positive pressure automatic regulator and the negative pressure automatic regulator are based on the pressure values measured by the pressure detector, respectively adjusting the positive pressure air and negative Air, so that the pressure applied to the syringe with a preset pressure value. Other aspects of the invention will be set forth in the description which follows, and in part will be obvious It is to be understood that the foregoing general description [Embodiment] The present invention will be described in more detail later with reference to the related embodiments of the present invention. However, the invention may be embodied in different forms and should not be construed as limiting the illustrated embodiments. For the sake of clarity, the exemplary embodiments are provided to make the disclosure more thorough, and will fully convey the hair duck 4 to those skilled in the art, in the drawings 'for clarity, it is possible to exaggerate the size and relative size of the layers and regions. Like reference symbols indicate similar elements. Figure 2 is a perspective view showing a dispensing machine 10 9 200932378 13 , = = T __ U, platform 12, head support unit self-frame 牟, and controller (applied to the application) according to an embodiment of the present invention. ). The platform 12 is placed on the frame 11. The substrate s of the shelf 11 is disposed on the platform 12. Move in the γ'-axis direction \^ Slide from the first-actuation 11 (not shown) in the X-axis direction. σ can be placed on the platform 12 by a second axis actuator (not shown) ❹ 轴 axis: The head tower unit U· extends to the X actuator (not shown. The head swing unit 13 can be cut by the third axis and can be moved in the X-axis direction of the X head unit. The nozzle 23 of the glue nozzle 22 is connected. The nozzle ^ 221 = _, to change the spray can be fixed to the coating head by the lifting portion... If the lifting portion is lifted, the second:: the coating head 23 of the rising portion. If the coating head 10 200932378 provides the distance detector 26 beside the nozzle 22. The distance detector 26 measures the distance between the substrate S and the nozzle 22 and provides the measured distance value to the controller. The controller is based on the measurement. The distance value controls the height of the nozzle 22. Similarly, the controller controls the first to fifth actuators such that the nozzle 22 is movable relative to the substrate s. Meanwhile, the pneumatic supply unit 1 shown in Fig. 4 can be mounted. In the syringe 24. The pneumatic supply unit 100 supplies air having a predetermined pressure to the syringe 24 to apply a predetermined pressure in the syringe 24. The predetermined pressure applied to the syringe 24 serves as a coating pressure for discharging the glue from the nozzle 22. From the nozzle 22 The amount of glue discharged depends on the coating pressure. As shown in Figure 4, the gas The supply unit 100 includes a positive pressure automatic regulator, a negative pressure automatic regulator 120, and a pressure detector 13A. The positive pressure automatic regulator 110 receives positive pressure air from the positive pressure air supply source 101. Ο Positive pressure air can be cleaned Dry air (CDA). The positive pressure automatic regulator 110 adjusts the pressure of the received positive pressure air and supplies the regulated pressure air to the injector 24. The negative pressure automatic regulator 12 is received from the negative pressure air supply source 1〇2. Negative pressure air. The negative pressure automatically adjusts the H 12G to adjust the pressure of the received negative pressure air, and supplies the adjusted pressure air to the injector 24. The pressure detector 13 measures the air pressure, wherein the self-positive pressure automatic regulator The positive pressure gas is mixed with the negative pressure air 200932378 supplied by the self-negative pressure automatic regulator 12 。. The positive pressure automatic regulator 110 and the negative pressure automatic regulator 120 are respectively adjusted based on the measured pressure value The pressure of the positive pressure air and the pressure of the negative pressure air cause the coating pressure in the syringe 24 to have a preset value. The positive pressure automatic regulator 110 and the negative pressure automatic regulator 120 can be controlled by the controller 3〇. The pressure value measured by the device 130 can be supplied to the controller 30. Therefore, the controller 30 can control the positive pressure automatic regulator 110 and the negative pressure automatic regulator 120 based on the pressure value received from the pressure detector 130, so that The pressure of the cloth in the syringe 24 has a preset value. For example, if the preset coating pressure value applied to the syringe 24 is input to the controller 30' controller 3, the pressure measured by the pressure detector 130 is compared. The value and the preset coating pressure value. If the measured pressure value is less than the preset coating pressure value, the controller 30 controls the positive pressure automatic regulator 110 to measure the difference between the measured pressure value and the preset coating pressure value. To increase the pressure of the positive pressure air and supply the positive pressure air to the injector 24. ‘ At the same time, the controller 30 can control the negative pressure autoregulator 12A to increase the pressure of the negative pressure air and supply the negative pressure air to the injector 24. At this time, the controller 30 controls the positive pressure automatic regulator 11 〇 and the negative pressure automatic regulator 12 〇 so that the air pressure of the air mixed negative pressure air reaches the preset coating pressure. Therefore, the coating pressure in the injector 24 can be equal to the preset pressure. The measured pressure value on the right is greater than the preset coating pressure value, and the controller 3〇 controls the positive pressure 200932378. The automatic regulator 110' reduces the pressure of the positive pressure air by the difference between the measured pressure value and the preset coating pressure value. 'And simultaneously control the negative pressure automatic regulator 120 to reduce the pressure of the negative pressure air. As described above, the pneumatic supply device 1 according to the current embodiment of the present invention simultaneously adjusts the pressure of the positive pressure air and the pressure of the negative pressure air, thereby changing the coating pressure to the preset pressure. The current embodiment uses two regulators (ie, positive pressure and negative pressure automatic adjustment φ) to change the coating pressure, which can be changed in a shorter time than a comparative example in which the pressure is changed by a single positive pressure automatic regulator. pressure. For example, if the coating pressure is changed in the same ratio, the current embodiment can change the coating pressure to a preset pressure in a shorter time (at least half of the time taken by the comparative example) than the comparative example. Therefore, the current embodiment as shown in FIG. 6 can be more linearly (four) stronger than the comparative example. At the same time, the coating pressure can be changed almost linearly within the allowable range by appropriately touching the time taken to form the corner portion of the pattern. The pneumatic supply device (10) utilizes the positive pressure automatic regulator 11G and the negative pressure automatic, and the regulator 120* adjusts the pressure to achieve fine vacuum control. Similarly, since the device just contains the vacuum autoregulator (10), the pneumatic supply (10) is immersed, after termination, or when the coating remains fixed, the control pressure will remain at the tip of the nozzle. 13 ❹ ❿ Change 200932378 § There is no need to automatically adjust the 1111G supply from the positive I to the note ’ 1〗 5 T Avoid supplying positive air to the syringe 24. The negative pressure valve 125 is used to open or close the air flow between the negative movements 2 . The negative fine 125 prevents the supply of negative dust air to the injector 24 when self-fine motion is not required. The main house valve 115 and the negative display 125 can be controlled by the controller 3〇. The method of finely having the above-mentioned _ 1 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 21-bit map 2 says that the moving speed of the head unit 21 of 2 _ is changed with respect to the position of the head unit 21, and the movement of the platform 12 shown in FIG. 2 = the pattern of the change ^ 6 is the nozzle shown in FIG. 22 The pattern of changing the roofing force is applied, and FIG. 7 shows the position where the coating glue forms a rubber pattern. The change in coating speed as shown in Figs. 5 and 6 corresponds to the sum of the change in the head unit speed Vx and the change in the moving speed Vy of the stage 12. Referring to FIGS. 6 and 7, the coating speed will be changed before the deceleration start-up L1, and the coating speed will be changed to the straight line due to the deceleration start position L1 in the first-line coating area M, and the reduction can be a curve. Touch the preset position of L2 before the position. From "set L1 14 200932378 at the deceleration start position Li, start to lower L3 to decrease to the curve coating speed V2. 诘疋 且 and %, the end of the war position π 疋 。. The deceleration end position L3 can be equal to L2. Therefore, at the deceleration start position u and the deceleration end position: = the ground reduction coating speed. The linearity can then be linear from the deceleration end position L3 to the acceleration start position (4) ❺ ❹ degree to the curve coating speed V2. Acceleration start position L4 It can be equal to the end position of the curve ❿ successively, from the acceleration starting position u to the acceleration end position L6, the selection acceleration to the straight line velocity V1. The secret acceleration end position L6 is located in the straight line coating area A3, and the acceleration end position L6 can be the passing curve After the end position L5 = set position. This increases the coating speed between the touch point u and the secret position L6. The distance between the acceleration start position u and the secret position L6 can be the same as the deceleration start. The distance between the position L1 and the deceleration end position L3. From the acceleration end position L6, the coating speed is maintained at the linear coating speed ^: The coating speed is changed by the above method, as shown in Fig. 5, the platform 12 can be from the curve starting position. L2 The acceleration end position L6 is accelerated. Here, the acceleration end position L6 passes the curve end position [5. Therefore, when the straight coating speed VI is increased compared to the case where the conventional acceleration end position L6 is before the curve end position L5, A lower impact on the platform 12 to initiate the maintenance of the fixed platform 12. 200932378 When the weight of the fresh ft ground J platform 12 is increased, a lower impact is applied to the conventional case. 12.,,. And increase the speed of the coating glue, thereby avoiding the problem that the partial curve of the curve is slightly different.
當頭單元31停止時，平台12可以相同方式停止。亦即，平 台12自減速起始位置L1減速且於曲線終點位置L5停止。於此， 減速起始位置L1可於曲線起始位置^2之前。 ^因此，相較於習知減速起始位置L1紐過曲線起始位置L2 後之案例，g直線塗佈速度VI增加，施加較低的衝擊到平台12， 以停止移動中的平台12。 同時，類似地，當頭支撐單元13而非平台12移動時，較習 知案例施加較低的衝擊到頭支撐單元13，以啟動或停止頭支撐 單元13。 · 於減速起始位置L1及加速終止位置L6之間，塗佈速度低於 直線塗佈速度VI。若每小時自喷嘴22排出之膠量為固定，則塗 佈於減速起始位置L1及加速終止位置L6間之膠的寬度及高度將 變得大於以直線塗佈速度VI塗佈之膠的寬度及高度。 因此，為了調整每小時自噴嘴22排出之膠量，必須調整塗 佈麼力。以下參考圖6 ’將δ羊細描述塗佈壓力的調整。 16 200932378 於減速起始位置Ll，塗佈壓力維持於直線塗佈壓力P1。當 塗佈速度自減速起始位置L1減速時，開始降低塗佈壓力且於減 速終止位置L3達到曲線塗佈廢力p2。 於此’曲線塗佈壓力P2及曲線塗佈速度V2可設為預設值， 使得於曲線塗佈壓力P2下塗佈於曲線塗佈速度V2之膠之寬度及 U 尚度’相等於直線塗佈壓力P1下塗佈於直線塗佈速度¥1之膠之 寬度及面度。同樣地’於減速起始位置Li及減遂終止位置L3 間，可以相同於塗佈速度之減速比例降低塗佈壓力。因此，塗佈 ，減速起始位置L1及減速終止位置[3間之膠的寬度及高度變得 等於第一直線塗佈區A1所形成之直線部份的寬度及高度。 塗佈壓力於減速終止位置L3降低至曲線塗佈壓力？2後，自 減速終止位置L3到加速起始位置L4，維持塗佈壓力於曲線塗佈 ，力P2。因此，曲線塗佈區A2形成之曲線部份的寬度及高度變 彳于等於第一直線塗佈區所形成之直線部份的寬度及高度。 然後，自加速起始位置L4到加速終止位置L6，塗佈壓力增 力:至直線塗佈壓力P1。於此’可以相同於塗佈速度之增加比例 增加塗佈壓力。因此，塗佈於加速起始位置L4至加速終止位置 L6間之膠的寬度及高度變得等於第二直線塗佈區所塗佈之膠 的寬度及高度。 200932378 於加速終止位置L6後，維持塗佈壓力於直線塗佈壓力P1。 結果第二直線塗佈區A3形成之直線部份的寬度及高度變得等 於第一直線塗佈區A1所形成之直線部份的寬度及高度。如上述 藉由改變塗佈壓力，整個膠圖案之定度及高度變成一致的，因而 達到膠圖案的一致性。 同時，當改變塗佈壓力時，若改變喷嘴22(見圖3)及基板 Φ S(見圖2)間之距離’喷嘴22塗佈之膠的寬度及高度變得不同於 預設的寬度及高度。因此，當塗佈壓力改變時，喷嘴22犮基板 S間之距離必須維持一致的。 於其他範例中，如圖8所示，若減速起始位置L1於曲線起 始位置L2之前，則減速終止位置L3可於曲線起始位置L2之前。 同樣地，若加速終止位置L6通過曲線終點位置L5後，則加速起 始位置L4可通過曲線終點位置L5後。於上述實施例中，於減速 起始位置11及減速終止位置L3間降低塗佈壓力，以及於加速起 © 始位置L4及加速終止位置L6間增加塗佈壓力為相同的。 又於另一範例中，如圖9所示，減速起始位置L1等於曲線 起始位置L2。於此案例’減速終止位置L3通過曲線起始位置L2 之後。同樣地’加速終止位置L6可等於曲線終點位置L5。於此 案例’加速起始位置L4於曲線終點位置L5之前。於上述實施例 中，於減速起始位置L1及減速終止位置L3間降低塗佈壓力，以 及於加速起始位置L4及加速終止位置L6間增加塗佈壓力為相同 18 200932378 的。 如上所述’根據本發明當前實施例塗佈膠之方法中，當增加 直線塗佈速度，較習知案例施加較低的衝擊到維持固定或移動中 的平台以啟動或停止平台。同樣地，當平台重量增加，較習知案 例施加較低的衝擊到平台，而降低平台的震動。同樣地，當頭^ 撐單元而非平台移動時，較習知案例施加較低的衝擊到頭支撐單 e 元以啟動或停止頭支撐單元，而降低頭支撐單元的震動。因此， 可增加塗佈速度，且可避免膠圖·案之曲線部份形狀與預設形狀 同的問題。 v 同樣地，當改變塗佈速度時，藉由改變塗佈壓力，以避免所 塗佈膠的寬度及高度增加，而使膠圖案之寬度及高度變成一致 的。因此，可確保膠圖案的一致性。 當形成膠圖案的角落部份時，由於根據本發明去 ° ，供應裝置⑽改變塗佈壓力，因此可形成“形狀之膠圖 案。同樣地，於終止塗佈後或當點膠機維持固定時，由於氣動供 應裝置100可控制壓力以抽吸回殘留於噴嘴頂端的膠。因此 動供應裝置100可達到精細的真空控制。 本發明可應用於關於點膠機之各種技術領域。 雜本發日似參照特料紐實闕_細肺然而熟此 19 200932378 技術領域者應明瞭在不悖離本發明申請專利範圍界定之精神與 範嘴下可有各種修改及變化。因此，本發明意欲涵蓋所附申請專 利範圍之範脅及其均等物所提供之修改及變化。 【圖式簡單說明】 包含所附圖式以提供本發明進一步的了解，並結合且構成說 明書之-部份，說明本發明之例示實施例，並與說明一 ❹ 發明觀點。 圖1顯示塗佈於基板上之膠圖案範例； 圖2為應用根據本發明實施例塗佈膠方法之點膠機之透視 圖； 圖3為圖2所示之頭單元之透視圖； 圖4顯示用以執行根據本發明實施例塗佈膠方法之氣動供 應裝置之方塊圖； " 圖5及6為說明根據本發明實施例塗佈膠方法之圖式； 〇 圖7顯示塗佈膠形成膠圖案之位置； 例.顯示圖6所示之減速終止位置及加速起始位置之其他範 苑例圖9顯示圖6所示之減速起始止位置及加速終止位置之其他 【主要元件符號說明】 1膠圖案 直線部份 20 2 200932378When the head unit 31 is stopped, the platform 12 can be stopped in the same manner. That is, the platform 12 is decelerated from the deceleration start position L1 and stopped at the curve end position L5. Here, the deceleration start position L1 may be before the curve start position ^2. ^ Therefore, as compared with the case where the conventional deceleration start position L1 is past the curve start position L2, the g linear coating speed VI is increased, and a lower impact is applied to the stage 12 to stop the moving platform 12. Meanwhile, similarly, when the head supporting unit 13 is moved instead of the stage 12, a lower impact is applied to the head supporting unit 13 to start or stop the head supporting unit 13 than in the conventional case. • The coating speed is lower than the linear coating speed VI between the deceleration start position L1 and the acceleration end position L6. If the amount of glue discharged from the nozzle 22 per hour is fixed, the width and height of the glue applied between the deceleration start position L1 and the acceleration end position L6 will become larger than the width of the glue applied at the linear coating speed VI. And height. Therefore, in order to adjust the amount of glue discharged from the nozzle 22 per hour, it is necessary to adjust the coating force. The adjustment of the coating pressure will be described in detail below with reference to Fig. 6'. 16 200932378 At the deceleration start position L1, the coating pressure is maintained at the linear coating pressure P1. When the coating speed is decelerated from the deceleration starting position L1, the coating pressure is lowered and the curve coating waste force p2 is reached at the deceleration end position L3. Here, the 'curve coating pressure P2 and the curve coating speed V2 can be set to preset values such that the width of the glue applied to the curve coating speed V2 at the curve coating pressure P2 and the U-degree is equal to the straight coating. The width and the width of the glue applied to the straight coating speed of ¥1 under the cloth pressure P1. Similarly, between the deceleration start position Li and the decrease end position L3, the coating pressure can be lowered in the same manner as the reduction ratio of the coating speed. Therefore, the width, the height of the glue between the coating, the deceleration start position L1, and the deceleration end position [3] becomes equal to the width and height of the straight portion formed by the first straight coating area A1. Is the coating pressure lowered to the curve coating pressure at the deceleration end position L3? After 2, from the deceleration end position L3 to the acceleration start position L4, the coating pressure is maintained at the curve coating force P2. Therefore, the width and height of the curved portion formed by the curved coating region A2 become equal to the width and height of the straight portion formed by the first straight coating region. Then, from the acceleration start position L4 to the acceleration end position L6, the pressure is applied to the linear coating pressure P1. Here, the coating pressure can be increased in proportion to the increase in the coating speed. Therefore, the width and height of the glue applied between the acceleration start position L4 and the acceleration end position L6 become equal to the width and height of the glue applied to the second straight coating area. 200932378 After the acceleration end position L6, the coating pressure is maintained at the linear coating pressure P1. As a result, the width and height of the straight portion formed by the second straight coating region A3 become equal to the width and height of the straight portion formed by the first straight coating region A1. By changing the coating pressure as described above, the degree and height of the entire glue pattern become uniform, thereby achieving the consistency of the glue pattern. At the same time, when changing the coating pressure, if the distance between the nozzle 22 (see FIG. 3) and the substrate Φ S (see FIG. 2) is changed, the width and height of the glue coated by the nozzle 22 become different from the preset width and height. Therefore, when the coating pressure is changed, the distance between the nozzles 22 and the substrate S must be kept uniform. In other examples, as shown in Fig. 8, if the deceleration start position L1 is before the curve start position L2, the deceleration end position L3 may precede the curve start position L2. Similarly, if the acceleration end position L6 passes the curve end position L5, the acceleration start position L4 can pass the curve end position L5. In the above embodiment, the application pressure is lowered between the deceleration start position 11 and the deceleration end position L3, and the application pressure is increased between the acceleration start position L4 and the acceleration end position L6. In still another example, as shown in Fig. 9, the deceleration start position L1 is equal to the curve start position L2. In this case, the deceleration end position L3 passes after the curve start position L2. Similarly, the acceleration end position L6 may be equal to the curve end position L5. In this case, the acceleration start position L4 is before the curve end position L5. In the above embodiment, the coating pressure is lowered between the deceleration start position L1 and the deceleration end position L3, and the application pressure is increased between the acceleration start position L4 and the acceleration end position L6 to be the same 18 200932378. As described above, in the method of applying the glue according to the current embodiment of the present invention, when the linear coating speed is increased, a lower impact is applied to maintain the fixed or moving platform to start or stop the platform than in the conventional case. Similarly, as the weight of the platform increases, a lower impact is applied to the platform than in the conventional case, and the vibration of the platform is reduced. Similarly, when the head unit is moved rather than the platform, a lower impact is applied to the head support unit e to start or stop the head support unit than the conventional case, and the head support unit vibration is reduced. Therefore, the coating speed can be increased, and the problem that the shape of the curved portion of the rubber pattern and the preset shape can be avoided can be avoided. v Similarly, when the coating speed is changed, the width and height of the glue pattern are made uniform by changing the coating pressure to avoid an increase in the width and height of the applied glue. Therefore, the consistency of the glue pattern can be ensured. When the corner portion of the glue pattern is formed, since the supply device (10) changes the coating pressure according to the present invention, a "shaped rubber pattern can be formed. Similarly, after the coating is terminated or when the dispenser is maintained stationary. Since the pneumatic supply device 100 can control the pressure to suck back the glue remaining on the tip of the nozzle, the dynamic supply device 100 can achieve fine vacuum control. The present invention can be applied to various technical fields regarding the dispenser. It is to be understood that the present invention is intended to cover various modifications and changes in the spirit and scope of the invention as defined by the appended claims. Modifications and variations of the scope of the invention and the equivalents thereof.
