Description of the Invention · [Technical Field of the Invention] The present invention relates to a method of applying a glue to a substrate. [Prior Art] ... In general, flat panel displays (FPDs) are video displays that are thinner than conventional cathode ray televisions or monitors. Examples of flat panel displays that have been developed are liquid crystal displays (LCDs), plasma display panels (pdps), field emission displays (FEDs), and organic light emitting diodes (OLEDs). Among many flat panel displays, the liquid crystal display is a display for supplying liquid crystal signals to the matrix based on image information, thereby controlling the transmittance of the liquid B cells and displaying the desired image. Since liquid crystal displays have advantages of being thin, light, and low in power consumption and operating voltage, liquid crystal displays have been widely used. A method of generally manufacturing a liquid crystal panel for a liquid crystal display will be described below. First, a color filter, a light sheet and a common electrode are formed on the upper substrate, and a thin film transistor (TFT) and a halogen electrode are formed on the lower substrate with respect to the upper substrate. Next, an alignment film is coated on the substrate, and the alignment film rubs to provide a liquid crystal molecule pretilt angle and an alignment direction to be formed in the liquid crystal layer between the alignment films. Further, in order to maintain a predetermined gap between the substrates to prevent liquid crystal leakage and to seal a gap between the substrates, a predetermined pattern of glue is applied to at least one of the substrates to form a glue pattern. Thereafter, a liquid crystal layer is formed between the substrates. In this way, a liquid crystal panel was fabricated. 201109089 η transfer machine used to form an egg case on the substrate. The applicator includes a head for the wire plate, a head with a turned nozzle, and a head support for the head unit. When such a glue applicator changes the position of each nozzle relative to the base, a glue pattern is formed on the substrate. Also, when the nozzles of the head units are moved up/down in the Z-axis direction to maintain a gap between the discharge holes of the nozzles and the substrate, the glue applicator horizontally moves the nozzles and/or the substrates to the x and γ axes. The direction, and the glue is discharged from the nozzle on the substrate' thus forming a glue pattern. When the pattern is formed on the substrate, the uniform gap between the substrate and the nozzle is maintained. The head sheets 7C are equipped with laser displacement sensing. The laser displacement sensor provides a gap between the nozzle and the substrate to obtain the gap between the nozzle and the substrate. Therefore, the control unit can make the gap between the nozzle and the substrate based on the execution of the control glue. That is, when the glue pattern is formed by moving the nozzle or the substrate horizontally in the X-axis and Y-axis directions, if there is a gap between the nozzle and the substrate, the gap, Newcom or other reasons, the visibility of the rubber pattern formed by riding and The degree of question can deviate from the preset range, thus causing a defective glue pattern. In order to solve this problem, the coated axis geiit has a laser position minus (four). The laser displacement sensor includes a transmitting portion that emits laser light to the substrate, and a receiving portion that receives the (four) light that is reflected from the upper surface of the substrate. At the same time, if the nozzle is moved to the coating start position on the substrate in the process of forming the glue pattern on the substrate by using the glue applicator, the laser position reducer measures the gap between the substrate and the nozzle, and the whistling element determines Whether the measured clearance is within the preset reference range. If the measured gap is not within the preset reference range, the coating operation is stopped. In this case, τ 'work M determines whether or not the substrate or nozzle needs to be corrected. 4 201109089 About the substrate and the nozzle __The error may be caused by the wrong lens of the nozzle or the sensor or the defective substrate (such as the curved substrate), when the measurement of the gap is caused by the laser The displacement of the displacement sensor. When the laser light emitted by the 臈 interferes with the alignment 涂布 applied to the substrate, or when the measurement is encountered, the laser light emitted by the f-shooting portion is incident on the receiving portion and is reflected by the surface. When reflected from the lower surface of the substrate, an error may occur. In the above reasons, when the measurement of the gap is caused by a wrong position of the nozzle or the laser displacement or a defective substrate (for example, a curved substrate), the glue coating operation is stopped, and then the operator must perform an additional operation. Procedure to correct the mounting position of the nozzle or laser displacement sensor or to replace the substrate. If the measurement of the gap is caused by interference from laser light or unusual = reflection, the substantial gap between the nozzle and the substrate may be within the pre-reference range. Therefore, in this case, the glue coating operation can be performed without requiring the operator to perform an additional operation. However, when an error occurs in a conventional glue application method, the glue applicator or the operator cannot accurately determine the cause of the error. Therefore, even if the error is caused by the interference of the laser light or the unusual reflection, the operation of the glue applicator is stopped, and it is a problem that the nozzle or the laser displacement sensor is poorly mounted or the substrate is defective. If the nozzle or laser displacement sensor has no problem of poor installation or the substrate has no defects, the glue applicator is operated to apply the glue to the substrate.如此 As a result, the conventional glue coating method has a problem in that even if the error is caused by the interference of the laser light or the unusual reflection, the operator must check the glue applicator after stopping the glue coating operation. Therefore, the time taken to form the glue pattern on the substrate is increased, and the productivity of the product is greatly reduced. SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a method of applying a coating, which reduces the time taken to form a glue pattern on a substrate, thereby increasing the productivity of the product. In order to achieve the above object, the present invention provides a method for coating a glue, and the second method comprises: recording the coating on the sprayed mosquito net, the gap between the plate and the nozzle, and measuring by the mosquito. Between = parameter range; (9) when the gap measured in step (8) is not preset, 'position the nozzle on the substrate different from the coating start position, set the 'two = in the second base test board = amount The measured gap is not within the preset reference range. The second stop (8) nozzle tip position, or one of the will. The eve position, the movable substrate and the nozzle are at least Ϊ Ϊ) may be included on the substrate for measuring the step between the substrate nozzles, and when on the substrate, the step (C) is performed. When the step (b) and the eucalyptus are within the pre-reference range, the measured substrate (B) and the nozzle B may be subjected to steps (d)/, B in all preset positions on the substrate. When the gap is not within the preset reference range, then 201109089 'simultaneous' may be used to avoid interference between the laser light emitted from the emission portion of the laser displacement sensor and the alignment film applied to the substrate, and step (b) may include Positioning the nozzle on the substrate where the alignment film is not applied, and measuring the gap between the nozzles at this position and determining whether the measured gap is in the preset parameter, in order to measure the substrate and the nozzle more accurately. The metal _ formed on the substrate reflects the laser light emitted by the laser displacement sensor, and the step (b) may include positioning the nozzle at the position of the second point, where the substrate and the nozzle are measured Between::= Is the gap measured in the 在 within the preset reference range. }, At the same time, even if step (9) is performed, between the substrate and the nozzle: when setting the parameter, the circumference is 'in order to inform the operator that the gap is not the same. = In the step-slip operation, it can also include production = nozzle 2 = can be included In order to achieve the above object, the present invention provides a method for: (4) positioning a nozzle on a substrate, measuring the starting position of the substrate and the nozzle, and coating Whether the cloth is positioned in the gap of the preset _ _ 4_ gap, the nozzle positioning the material board is not here to re-measure the position between the substrate and the nozzle, and the method of the glue, which is described. Ming/Yue Chu, the present invention provides coating 201109089. When the gap between the nozzle and the substrate measured at the priming position on the substrate is not within the preset range, positioning the nozzle on the substrate is different from the coating start. The pre-mixing of the position, without immediately stopping the coating operation, and re-measuring the f· between the nozzle and the substrate, and determining the re-quantity __ shirt in the predetermined range =. Therefore 'error is not _• or laser The position of the bit minus is offset by the substrate 'but because of the reciprocal ray emitted by the emitting portion of the laser displacement sensing 11, the conversion can be performed without stopping the earth force: the low performing glue coating operation is spent Time, thus increasing the life of the product [implementation] Referring to the accompanying drawings, a coating unit 40' head unit 50, a control d-moving member 30, and a head stand frame 10 according to a preferred embodiment of the present invention will be described.

In order to position the nozzle 53 at the 3-coating start position, the nozzle 53 can be moved by the early ft/cloth starting position SP by the second ft/cloth starting position SP, and the head unit 51 is moved, and the board ST is moved by the X-axis. First, by moving the heart = axis moves early 22 moves s]. The movement of at least one of the nozzles S, and the coating start position SP on the laser displacement, is also moved together with the mouthpiece 53. 201109089 So, if the nozzle 53 has been positioned on the substrate s, the emitter of the SP' laser displacement sensor 54: = the emitted laser light is reflected from the upper surface of the substrate S, and then the person is shot to the ejector 3 nozzle 53 The 卩 卩 (10) 早 早 & ° ° ° ° 。 。 。 。 。 。 。 。 。 。 。 。 。 Furthermore, in step S2, the detected gap is within a preset reference range. If the substrate gap is measured in the coating start position sp on the substrate S, the gap between the 53 is in the preset reference range, and the relative position between the control unit and the nozzle 53 is And the glue is discharged from the nozzle 53, so that in the Y step S5G, the egg shape p of the predetermined shape of the shaft is on the substrate s. = 'The gap between the substrate sj nozzle measured by the coating start position sp on the substrate s ^ is in the preset reference range _, then the nozzle 53 is positioned on the substrate S in step S3, unlike the coating The position of the starting position sp. f After measuring the gap between the substrate S and the nozzle 53, the position is determined in step 2, and the measured gap is at the preset reference range _. Here, at step ', the substrate S can be moved at least at different positions on the substrate s by moving the substrate S and the nozzle 53 at least. At this time, if the gap between the substrate S and the nozzle 53 measured at the position different from the coating start position 81 on the substrate S is within the preset reference range, the nozzle 53 is at step S40. ^The coating start position on the substrate s\ after the relative position between the substrate S and the nozzle 53 is changed, the glue is discharged from the nozzle 53, and thus, in step S5, a predetermined pattern of the glue pattern p is formed on the substrate. s. That is, if the gap between the substrate s and the nozzle 53 measured on the substrate s different from the coating start position sp = position is within the predetermined reference range, then the coating on the substrate S is determined. The base position measured by the start position sp 201109089 The gap between the plate S nozzles 53 is not in the preset reference range error occurs 'not because the nozzle 53 or the laser displacement senses the position of the wrong position 54 or the defective substrate S, and It is caused by the fact that f is light and unusual reflection. After the sprayer is printed at the coating start position, the glue is discharged to form a glue pattern P on the substrate S. At the same time, the laser light emitted from the emitting portion 541 of the laser displacement sensor 54 may be disturbed by the alignment film applied to the substrate s. When the nozzle 53 is clamped on the substrate s at a position different from the coating start position sp in step S31, it is preferable to set the different position at the portion where the alignment film is not applied. In general, ρ, since the alignment film is applied to the inner side of the glue pattern p, the nozzle Μ is disposed outside the glue pattern P. In this way, the nozzle 53 is located at a position where there is no alignment film, so the measurement point of the laser displacement sensor 54 is at a position where there is no alignment film, thereby allowing the gap between the substrate 8 and the nozzle 53 to be measured more accurately. . Further, a metal pattern (not shown) may be formed on the substrate s. Such a metal pattern enables the laser light to reflect more properly' without disturbing or otherwise reflecting the laser light. Therefore, when the nozzle 53 is positioned at a position on the substrate s different from the coating start position SP in step S31, it is difficult to set the position of the column in the portion where the metal pattern is formed. In this way, the nozzle 53 is located at a position where the metal pattern is formed, so the measuring point of the laser displacement sensor 54 is in the position where the metal is formed, thus allowing the smoother reflection of the laser light, and more accurately. The gap between the substrate S and the nozzle 53 is measured. θ Meanwhile, if the gap between the substrate S and the nozzle 53 measured on the substrate S different from the position of the coating start position SP is not within the preset reference range, the formation of the glue pattern P on the substrate is stopped in step S6G′ s operation. That is, 12 201109089 When the _ between the substrates s and 53 measured at a position different from the coating start position SP is not in the preset reference range (4), the coating start position sp on the substrate § is determined. The gap between the measured substrate s and the nozzle 53 is not caused by the error of the preset reference pattern, and the position of the substrate s is not the same as the position of the coating start position sp on the substrate s. The error in the preset reference range occurs, not because the interference of the laser light is not reflected, but because of the installation position of the nozzle 53 or the laser displacement sense, 54 or the defect S. Therefore, the operation of applying the glue is stopped in step _. At this time, the operator is notified of the operation status, and in the step ^ Λ 再 再 ' 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 53 53 53 53 53 53 53 53 53 53 53 53 53 53 53 53 53 53 53 53 53 53 53 53 53 - A flow chart of a method of applying a glue. As shown in FIG. 6, step S1 and face S2 are the same as the previous embodiment, and will not be described again. In step S3, the nozzle 53 is positioned on the substrate s at a position other than Sp at the coating start position. In step S32, at this position amount = plate S, the gap between the nozzles 53 is closed, and then it is determined that the measured gap is = at the preset reference. Step 3, including step M and step Μ, can be executed at least once. For example, # preset reference range _ at the coating start position sp, positioning the nozzle 53 on the substrate S different from the first position of the coating start position SP, and whether the gap is within the preset reference range. If it is in the first position, the nozzle 53 is moved to the coating start position to perform the coating operation. Here, if the measurement is performed between the first position and the pre-5 tea test, the nozzle 53 is positioned on the substrate s, the amount, the gap, and the quantity is determined. Preset reference range. As a result, if the gap measured at the second position is within the range of the preset reference 201109089, the nozzle 53 is moved. In the autumn, if the starting position of the cloth is SP, and the glue coating is performed, then (4) the mouth 53 is moved to the position of the measured reference material in the preset reference measurement, the gap is measured, and the gap is determined. The amount is within the reference range. This can be performed repeatedly. Controllable set to perform repeated operations. If it is within all predetermined number ranges; the gap between == and 53, is not in the preset reference, and the operation of forming the glue pattern p is stopped in step S6G'. The position between the substrate S and the nozzle 53 measured by the gap is the same as the coating start: the SP gap: the position is moved, and the position of the nozzle 53 to the unusable ti may be one or more. As described above, the "off" between the substrate s and the nozzle 53 may be the portion where the alignment film is not applied, or the portion where the metal is formed. Fig. f HI 7 is the root - according to the present invention - The flow of the method for coating the adhesive is as follows: "'# is not at the coating start position but at the substrate s - butterfly 5: the gap between the substrate S and the nozzle 53 is measured, When it is not in the pre-enclosure, the operation of forming the rubber pattern is stopped in step S60. The second, second, and second nozzles, or the mounting position of the laser displacement sensor 54 is positive or not, and the alumina board s is defective. In step S8G, the calibration can be performed as 0'. As described above, the present invention provides a method for applying a glue, wherein the gap between the nozzle and the substrate measured in the coating of the position of the runner is not in the preset reference. Positioning the nozzle at a predetermined position on the substrate without immediately stopping the glue coating operation, and re-measuring the nozzle and the substrate The gap, and the decision whether the gap of 201109089 is within the preset range, so when the error occurs not because of the wrong position of the nozzle or laser displacement sensor or the defective substrate, but because of the laser displacement sensing When the laser light emitted by the emitting portion of the device is caused by interference or unusual reflection, the execution of the glue coating operation is not stopped, thereby preventing the operator from unnecessarily checking the operation and reducing the time taken for applying the glue.
