Description of the Invention: [Technical Field] The present invention relates to a method for controlling a seai dispenser apparatus, and more particularly to an adjustment pitch sensor (gap sensor) A method of distance from a nozzle of a sealed sprayer for applying sealants. [Prior Art] A conventional display device includes a cathode ray tube (CRT). However, CRTs are larger and heavier. Therefore, the use of flat panel display panels such as liquid crystal display devices (LCDs), plasma display panels (PDPs), and organic light-emitting devices (OLEDs) is increasing because Light and flat, and consumes less power. A flat panel display panel is manufactured by combining a pair of flat type substrates. For example, in the case of manufacturing an LCD, first, a lower substrate and an upper substrate are fabricated, wherein the lower substrate includes thin film transistors and pixel electrodes (pixei eiectrodes), and the upper substrate includes a color filter (color filter) And the common electrode (c〇m_n electrode). Subsequently, the liquid crystal is dropped onto the lower substrate and the sealant is applied to the edge region of the lower substrate. Subsequently, the lower substrate and the upper substrate are bonded together after the side of the lower substrate on which the pixel electrode is formed to be disposed to face the two sides of the upper substrate on which the common electrode is formed. Here, a seal sprayer device is used to apply the sealant. The sealant is applied along the edge regions of the substrate using a conventional depletion spray benefit device. ' 201023977 jWipif.d〇c At this point, a technique for precisely controlling the spacing between the substrate and the two 3 / main nozzles of the sealed sprinkler device is required. That is to say, in the case where the spacing between the substrate and the spray is very small, the pattern of the applied sealant will become wider and the degree of the wood will become smaller. On the other hand, in the case where the distance between the substrate and the nozzle is large, the width of the sealant pattern on the substrate is changed/the adhesive pattern is discontinuous', i.e., some portions of the sealant pattern are lost. At this time, although the sealant pattern is formed by applying the sealant to the substrate, the surface unevenness of the substrate or the separate layer is formed on the surface of the substrate, and the pitch between the lower nozzle and the substrate is changed. - the mouth of the fish, the nearest sputum sealer device further contains a measuring spray

Therefore, the odor 喷嘴 _ nozzle and the base red _ spacing are constantly maintained to maintain the base = nozzle spacing to prevent failure of the seal pattern. The assembled product is equipped with a nozzle, a nozzle and a distance sensor. The actual distance and change between the pitch sensors. ". The actual distance may also change during the nozzle change? The measuring point of the sensor changes due to the distance between the nozzle and the spacing sensor. That is, the pitch sensor becomes an undesired distance between the measurement base regions. Therefore, the sealant pattern is changed. For example, the difference in distance between the nozzle and the spacing sensor causes an I problem: the spacing sensor measures the base separation in the base region where the film layer is formed instead of measuring the base region in which the sealant is applied. The distance between the base and the mouth. 201023977 j^zvipif.doc Therefore, the distance between the nozzle and the distance sensor should be accurately measured. Various measurement techniques have recently been proposed to measure the length of the distance between the nozzle and the spacing sensor. In the measurement technology, there is a method of measuring the method described in Korean Patent No. 0-752237, and this will be described later. According to the Korean patent No. 2237, the Y-axis paste applying unit = the nozzle bottom of the shaft in the Y-axis direction is formed on the wire, and is sensed by the moving distance on the 1_ χ axis ^ The distance between the nozzle and the spacing sensor applied in the 5-axis direction is scanned by the scanning shaft. The application unit (Χ__ aPPlying_ is formed by moving the nozzle or the substrate in the X-axis direction, and calculates the γ-spacing sensor by moving the spacing surface 11 or the wire at γ f and scanning the X-axis paste applying unit Therefore, the distance between the nozzle and the distance sensor can be measured by the length Γσ, and the process is to measure the distance between the nozzle and the distance sensor, and the 4-step process is performed. The gap between the distances between the detectors is more than the scales _ the number of nozzles and the spacing senses the crying plus. The training me) becomes longer and the sealing sprayer moves and the suspension period is increased. Less accurate. Therefore, the application process of the application unit is combined with the time difference between the application of the paste application sheet (10) 2 201023977 ipif.d〇c, and a slight difference between the application processes is generated. This is because the syringe moves slightly and the syringe moves again after a longer period of time. The difference between the application processes causes a change in the shape of the x-axis and the γ-axis paste application unit (e.g., the pattern width of the application unit). Therefore, the position of the center point of the X-axis and the 膏-axis applying unit for measuring the distance is erroneous, and thus the accuracy of the measurement is lowered. SUMMARY OF THE INVENTION The present invention provides a method for controlling a sealed sprinkler apparatus that is capable of reducing the time required to measure a distance length between a nozzle and a pitch sensor, and increasing the measurement of the distance length.

The test substrate 201 is placed on the stage 100 in accordance with the square of the distance between the distance sensor 2 of the sealant dispenser 200 and the spray. „, as depicted in FIG. 3, in step _, the sealant is applied by the nozzle 210 of the syringe 220 to form a seal pattern for testing the distance measurement on the substrate 201, wherein the sealant pattern 2〇4 has a cross shape. At this time, the nozzle 21 (four) moves the coordinate information when the shape of the rubber pattern 2G4 is stored. 移动 by moving the sealant 7 in the first-axis direction (for example, the +-axis direction) (ie, 'nozzle addition') Forming a first sealant line extending in the direction of the first axis on the test substrate 2〇. Subsequently, by the second direction of 12 201023977 ^^-vipif.doc (for example, the -Y axis direction) Moving over the nozzle _ while forming on the second axis in the test basal period; ^ (p, spraying the second sealant line 203, wherein the second axis direction is perpendicular to the weight of the first axis, the first glue line 202 and The second adhesive line 203 is a central point 〇. That is to say, the first sealant 匕 is stacked. The first glue line 203. For this purpose, the formation of the _ / shape + straight to prevent by The nozzle is applied. The nozzle 21 moves in the opposite direction (for example, the X direction), and then the direction of ^^ (for example, , + γ axis direction) moves upward in the direction of the second axis by the application of the seal. Therefore, the nozzle 2 = shape (four) egg case, its towel ten (four) (four) mosquito point Ϊ is in the middle, formed on the test substrate The encapsulation pattern on 201 is 2〇. In this case, the movement of the nozzle 210 having the linear movement ί ^ 2U) is obtained by the transfer unit control unit _ movable similar to the broken line in Fig. 5 to obtain the displacement of the nozzle 21 〇 At the crucible, the data of the movement of the nozzle 21〇 can be set as the virtual reference block =, P and /. Therefore, the center and the point become the zero point of the virtual reference coordinate. : After 'in step S110' by using the pitch In the sensor measurement, there is a cross-shaped seal pattern 2Q4 center point device 24. Qing degree. Here, you can use the virtual reference coordinates to calculate the distance length. That is, ^, borrow The center point 封 of the sealant pattern 204 of the sub-shape is found by moving the pitch sensor MG as shown in Fig. 5. At this point, the zero points X〇 and Y〇 of the coordinate can be based on the virtual 13 201023977 Jmpif.doc 'Using the nozzle 2' 〇's coordinates and γ〉 to calculate the nozzle 210 and the spacing sensor 2 4 The length of the distance between the turns. This will be described in detail below. After forming the seal pattern 2 〇 4 having the cross shape illustrated in Fig. 4, the seal application by the nozzle 210 is prevented. The nozzle 2] is located at one end of the - - axis of the virtual reference coordinate, and the spacing sensor 24 is disposed in the fourth quadrant of the virtual reference coordinate. As described above, the spacing sensor 240 is used to search for the sealing pattern 2〇4 The center point is 0. When the center point 0 is searched, the thickness τ of the sealant pattern 204 is measured and the point at which the measured thickness has the maximum value is searched because the center point 0 of the sealant pattern 2〇4 is placed in a cross shape The lines of the two seal patterns 2〇4 overlap each other in the area. For this purpose, the area of the pitch sensor 240 having the smallest output value is detected by moving the pitch sensor 24A. Therefore, the area of the pitch sensor 240 having the smallest output value becomes the center point. As indicated above, the center point is easily found in this embodiment, so that the distance sensing time can be reduced. As depicted in Figure 5, the pitch sensor 240 is located at zeros Υ0 and Υ0 of the virtual reference coordinates. Therefore, the length of the distance between the nozzles 21 and the pitch detectors 240 can be calculated by detecting the coordinates Χχ and Yy of the nozzles 210 when the pitch sensor 24 is at the zero point. At this point, the coordinates of the nozzle 21A can be measured or calculated by moving the motor of the pitch sensor 240 and the nozzle 210. The invention is not limited to this embodiment. Therefore, according to another embodiment, the center point can be measured after measuring the width W of the sealant pattern 204 because the lines of the two sealant patterns 204 having a cross shape (ie, the first sealant line 2〇2 and 201023977 jj^) Yipif.doc The second glue line 203) is a strip with a certain width: the width of the width W when the 'spacing sensor 2 4 〇 or the second two test r. Here, the change...there is a point at which the output value of the pitch sensor is reduced (i.e., the point of decrease), and when the distance sensor 240 is removed, the point at which the production is moved in the side of the side is increased (i.e., the point of increase) = The measured value eventually increases the critical door LJ because the brother's glue line 202 has a certain exhibition. Therefore, the line of the word between the decreasing point and the increasing point has the same wide yield, ^^. Because the width of the two sealing patterns is sufficient, and the mouth is sufficient to ensure any of the sealing patterns 204, the thickness τ of the sealing pattern 2〇4 is measured from the wheel of the sensor 240. Point technology area, because the seal chart 1 =:: ° or reduced area, the overlap of the lines of the glue pattern 204. ^ The center of the two core points with ten sub-shapes set ° ^, will The middle shape of the sealant pattern has a width corresponding to the second degree w of the width ^=4 in the central point region of the sealant field. Therefore, like this, the point of the abundance becomes the center point. 〇. Class placement of the two appliances (4) The center point in the above description "center, or may be the gap residual, then! / then the back side of the gap sensor In addition, the measurement point here is the laser spot. Here, it is found that the nozzle 21〇 can be placed at the zero point of the virtual reference coordinate after forming the sealant figure 201023977 33291pif.doc * 240. Thereby, the measurement range of the pitch sensor 240 can be reduced to find the center point of the sealant pattern 204 using the pitch residual detector 240. Moreover, a +small = pitch sensor 24 can be added. Distance length; required to calculate the distance between the nozzle 2H) and the spacing sensor by the distance calculated by the distance (ie, the measured distance = degree of the set point is compared.

According to another embodiment both. In this embodiment, the distance between the nozzle 210 and the pitch sensor 240 is measured using the camera 270, and the length of the distance between the nozzle 21A and the pitch sensor 240 is adjusted in accordance with the measurement result. Hereinafter, a method for adjusting the length of the distance between the nozzle 2 and the distance sensor 240 using the camera 27 will be described. Fig. 7 illustrates a flow chart for explaining a method for adjusting the length of the distance between the pitch sensor 240 and the nozzle 210 of the sealant dispenser 200 according to the second embodiment. Figure 8 illustrates a plane 17 201023977 oozvipif.doc of the jig according to the second embodiment. Fig. 9 is a conceptual diagram for explaining a method for measuring the length of the distance between the sealant nozzle and the pitch sensor 240 according to the second embodiment. = Fig. 7 depicts that in step S2, there is a ten-shaped sealant pattern on the test substrate. Thereafter, in step S210, the camera 270 and the nozzle distance length values X1 and Y1 are calculated by measuring the center point of the specific seal pattern by the movement of the camera 2''. At this point, the center point of the sealant pattern is the virtual reference seat of the nozzle 21 〇-movement described in the embodiment. Therefore, the camera 270 is placed at the center of the seal having a cross pattern, and at this time, the distance length value of the phase 27 and the nozzle 21 is calculated using the coordinates of the nozzle 210 > The sealant map '^ dot area should be located in the center of the screen of the camera 270 to place the camera + 〇t female at the center of the sealant pattern. In this embodiment, the distance length of the camera 27A as a peripheral component can be measured based on the mouth 210. Thus, the length of the distance between the camera 270 and the nozzle 210 is adjusted. ^ After 'In step S220, the length of the distance between the camera 270 and the pitch sensor 240 is adjusted. • Use the jig 500 described in Figure 8 for this purpose. Here, the jig 5〇〇 includes a hole (h0]e) 510 at its center. The jig 500 is placed on σ 1 (10), and the pitch sensor 240 is placed at the center hole 51〇 of the jig 500. The output value of the pitch sensor 240 is increased in the area of the center hole 51 of the jig 500. Therefore, the area where the output value of the pitch sensor 240 is increased is regarded as the area of the center hole 510. Since the center hole 510 is centered on the circular shape 201023977 3^291pif.doc. The center zone of the distance length of both ends of the core hole 5]0 sets the beam of light to be a distance sensor 240 using a laser beam. Since the center of the mine fixture 500 can be used to visually position the pitch sensor _ at this point, the position coordinates of the pitch sensor 24 will be stored as the center point coordinates. ^, the center distance 240 of the 240 ^ X2 and Y2 machine 270 and the spacing sensor 240 is: "When the core hole 510 is placed at the center of the screen minus 270 = the center of the detector 240 The coordinates of the point coordinates and the position coordinates are γ2 again. X is the distance length value 相机2 of the camera 270 and the spacing sensor 240. ❹ The distance S using the camera 270 and the nozzle 210 in the distance S value S230 is longer than the distance between the camera 270 and the spacing sensor 240 by X2 and tY1. The distance of the G ^ Y23 nozzle 210 and the spacing sensor 240 _ mouth 2U) is said to be 'by calculating the distance between the camera and the jet _; Y1 and the camera 270 and the spacing sensor 240' The calculated mouth 210 and the pitch sensor are compared, and the length of the mouth is compared with the length of the money. Then, the mouth 21 is _ distance: i: ?25. The intermediate pitch sensor 240 and the 嗔19 201023977 In this embodiment, the length of the distance between the nozzle 2] 0 and the pitch sensor 240 can be measured based on the camera 270. As described above, the embodiment according to the present invention can be used every time the nozzle is changed at any time. The length of the distance between the nozzle and the pitch sensor is measured quickly and efficiently. And 'according to the embodiment of the present invention, the center position of the pitch sensor 240 can be obtained using the lost tooth 500 illustrated in Fig. 8. That is, the sense of pitch The laser beam of the detector 240 is disposed in the center hole 510 ' of the jig 500 and the coordinates at this time The position value is determined here. Here, the determination of the position value is based on the movement of the motor to find the position value. Further, 'according to the present invention', it can be verified that the pitch is sensed by moving up and down and left and right in the hole 510 of the clamp 5〇〇. The detector 240 causes the position of the pitch sensor 240 to change the output value, and sets the position of the corner or center value to ensure the center position of the pitch sensor 240. According to an embodiment of the present invention, Measuring and Adjusting the Distance Between the Nozzle and the Pitch Sensor by Using a Gap Pattern Domain Having a Cross 2 Using a Nozzle 2 to Measure and Adjust the Distance Between the Nozzle and the Pitch Sensor $ Implementation of the Invention For example, by using a pattern length and a phase (four) mouth and the distance between the senses of the gap _ long sound. §! θ,, according to an embodiment of the present invention, by using the test sealant pattern The maximum height and the center point of the sealant pattern of the maximum 2 pitch sensed shape, Nab: degree, has a cross shape 201023977 Μ. ipif.doc The accuracy of the measurement of the distance length.
