Description of the invention: [Technical field to which the invention pertains] Meta-measurement dispensing This is a method for supplying residual liquid in a single-purpose syringe by using pressure. [Prior Art] The display has a number of techniques to make the video display thinner than the conventional television and video display using a t-wire (4) thickness. Flat-panels that require continuous updates include liquid crystal displays, (s), plasma displays, field emission displays (FEDs), organic light-emitting diode displays (OLEDs), surface conduction electron emission displays (SEDs), and nanometers. Emissive display g^Ds), and electroluminescent display (ELDs) ° Liquid crystal display (LCD) is a thin flat-panel display device that is lined up in front of a light source or reflector by any number of !! colors and monochromatic pixels. Liquid crystal displays are widely used because they consume a very small amount of power. A liquid crystal panel as a liquid crystal display is manufactured by the following method. A pattern of color filters and common electrodes is formed on an upper glass substrate. A pattern of a thin film transistor (TFT) and a pixel electrode is formed on the glass substrate below the upper glass substrate. The rubbing alignment layer causes the crystal molecules between the two alignment layers to have a pretilt angle and a direction. 6 1335243 The dispenser is used to form a glue pattern on either the upper or lower glass substrate to seal the liquid crystal layer between the upper and lower glass substrates. Therefore, the LC dispenser is used to coat liquid crystal on a glass substrate formed by a glue pattern. The upper and lower glass substrates are combined to complete the liquid crystal panel. The upper and lower glass substrates are separated into discrete panels during scribing and splitting operations. The dispenser includes a base, a coating head unit, and a coating head support unit frame that supports the coating head unit. The coating head unit includes a syringe with a liquid crystal and a nozzle for coating the liquid crystal. When the nozzle and the substrate are kept at a fixed distance, by moving the pedestal of the substrate in the γ-axis direction, by moving the coating head unit in the x-axis direction, or by moving both in the Χ-Υ axis direction, The melter applies glue through the nozzle to form a glue pattern on the substrate. ^ When the glue is applied, the remaining glue in the syringe is slowly reduced. Injection 罘 is exhausted during coating, making the glue pattern less; before the measurement, it is necessary to check if the injection 11 in use has sufficient glue to decide to replace the new syringe, or to decide to apply it to the head unit. However, in the case where there is no more used Si: the ampoule measuring device does not = Danbeja, it also needs to adjust the position. The device is important & when will the financial injection poem be replaced with a new injection 7 1335243. Too early replacement is a waste of glue, too late replacement causes incomplete pattern formation on the substrate. In addition, it is important to accurately measure the amount of glue remaining in the syringe as accurately as possible. When the amount of remaining glue measured in the syringe in use is different from the actual amount of glue, the specific amount of glue cannot be applied. This is because the amount of remaining sputum that is applied to the injection 11__ 勤 着 转 使用 使用 使用 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 The syringe measures the remaining winnings less than the actual residual coating compared to the silicone. In the above, the pressure lower than normal will be applied to the glue, so [the invention] The device according to the present invention. The method of residual glue, the first gas in the ejector to the beginning of the empty syringe, the second reference pressure of the J: the new syringe to the pressure gas to contain the remaining glue to make "May 1 (1)) _ by the supply The mouth makes the ^^ emitter to the room, and (C) by using (the second time of the second point - the second a_) _ pair (the first - glue. The column is used in the syringe The other embodiments, features, aspects and advantages of the present invention will be apparent from the accompanying drawings. 1 Schematic diagram of a dispensing machine utilizing a method of measuring residual glue in a syringe in use in accordance with a specific embodiment of the present invention. Dispenser 100 includes a coating head support frame 102 that is slidable in one direction (eg, on the X-axis) The coating head unit 11 is provided on the coating head support frame 忉 2 ′ so that it can slide in a direction perpendicular to the moving direction of the coating head supporting frame 1 ( 2 (for example, in the γ-axis direction). A glue nozzle 丨丨丨 is provided to the coating head unit 110. Therefore, The nozzle ln is movable relative to the substrate in the x-axis direction and the x-axis direction to maintain a fixed distance between the nozzle in and the substrate ί. The beta dispensing machine 100 includes a pressure supply unit. The pressure supply unit supplies the gas to the injector 112 until The syringe 112 is pressurized to a target pressure (ΤΡ) that is glued to the substrate 10 via the nozzles. The pressure supply unit includes a regulator 12, a valve 122, and a sensor 123. The regulator 121 provides a gas, such as air or nitrogen, and The gas is pushed into the syringe at a constant pressure. The valve 122 controls the flow of gas from the regulator 121 to the injector 112. The sensor 123 senses the amount of pressure supplied to the syringe 112. Therefore, when the =J 121 provides a pressure equalizing gas, the sense Detector 123_injector ιΐ2 ': firm to target pressure (TP). Based on the sensor from the sensor 12, Ϊ, Ϊ glue coated through the mouth 111 'Note (four) 112 (10) glue amount reduced ^ j syringe 112 pressure amount with Remaining in the syringe 112 ° S' before and after the painting, it is necessary to measure the house strength of the syringe 112 to the injector 112, to pressurize, and the target pressure of the Tianhe mouth 111 to the substrate 1 。. Specific implementation For example, a flow chart illustrating a method of measuring the injector 112. Figure 3 shows a graph of the change in injection time. The i-knife is ready to measure the first-time amount (FAT) at step S21G, which is the start of the empty syringe. The time point (SPT) to the pressurized air injection '2 tT' is based on the supply of the gas to the new g-new syringe containing the initial amount of glue to the coating head unit UG when the original new injection, "Lai Ying Zao Yuansi The average filament is given to the residual sugar, and the force is pressed to the eye suspension (10). The change in pressure versus time is shown in Figure 1. The second time amount (SAT) is measured by the supply mean, and the spring 1335243 pressure supply unit supplies the pressure equalizing gas to the empty injector. The change in force versus time is determined by the distance between the two PtTi, (SPT) and the first time point (SRPT) of the reference vacuum (RP). n?m2 puller does not, for the New Zealand 11 plus Lang reference pressure because Γ) 1 new shot, press to the reference house force (RP) takes more time This 'first amount of time is greater than the second amount of time. In step S220, measuring a third amount of time (TAT), the third time point of the syringe to the reference pressure (RP), the pressure supply unit supplies the pressure equalizing gas to the syringe in use, and the lung injection in the direct use To the target pressure (τρ). The change in pressure versus time is shown in curve III of Figure 3. The third time amount J is the starting time point (spT) of the syringe in use = the third time point (top ^) of the pressure in use. And the empty injection is; t shot 5 internal dust force is stable against time ΐΡ, ΐ 15 I measured the remaining glue in injection 11. The reference pressure ΐϊΐ is between 9 ()% of the county power or the job ^. More specifically, the reference pressure (RP) may be 9% of the target pressure.

TAT ί ΓΑΤ. Because ίBQ is equal to 1Q. This means that the glue in the syringe in use is the amount of glue in the new/main shot. Assume that the syringe in use corresponds to an empty shot. ΤΑΤ is equal to FAT. Therefore, Bq is equal to 〇/(FAT SAT. This means that no glue remains in the syringe of the use order. The present invention provides a point at which the remaining glue in the syringe can be measured without having to mount the measuring device. Therefore, the syringe in use can be used. Replace the new syringe at the time of the pair. Therefore, the present invention provides another advantage in that a constant pressure is supplied to the glue in the syringe based on the remaining glue gauge. Therefore, the amount of glue is applied to the substrate via the nozzle. The month has been implemented in several forms without departing from the important features.
