[Prior Art] In general, flat panel displays (FPDs) are video displays that are thinner than conventional television or monitors that use cathode ray tubes. 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 (〇LEDs). In many flat panel displays, the liquid crystal display is a display that supplies data signals to the matrix cells of the matrix based on the image information, thereby controlling the transmittance of the liquid cell and displaying the desired image. Since liquid crystal displays are excellent in thinness, lightness, and low power consumption and operating voltage, liquid crystal displays have been widely used. A method of manufacturing a liquid crystal panel for a liquid crystal display will be described below. First, a color filter and a common electrode are formed on the upper substrate, and a thin film transistor (TFT) and a pixel 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 the gap between the substrates, a predetermined pattern of glue is applied to any of the substrates to form a month > Thereafter, a liquid crystal layer is formed between the substrates. In this way, the m 201109630 liquid crystal panel was manufactured. In the manufacture of a liquid crystal panel, a glue applicator is used to form a glue pattern on the substrate. The applicator includes a platform for mounting a substrate, a syringe filled with glue, a head unit having a nozzle for discharging glue, and a head support for the support head unit. Such a glue applicator forms a glue pattern on the substrate while changing the relative position between each nozzle and the substrate. That is, when the nozzles of the head units are moved up and down in the z-axis direction to maintain a gap between the nozzles and the substrate, the glue applicator moves the nozzles and/or the substrates in the X and γ axis directions, and discharges the glue from the nozzles. On the substrate, a glue pattern is thus formed. In order to discharge the glue from the nozzle, the same temple supplies the fluid to the injection n at a predetermined pressure, and the discharge pressure acts on the glue in the syringe. Further, in order to control the amount of glue discharged from the nozzle, the pressure supplied to the syringe is adjusted. The amount of glue contained is == full, and the syringe is frequently measured when the glue main cloth is finished or when the syringe is replaced. The method of measuring the amount of glue contained in the syringe by measuring the amount of the glue contained in the gel contained in the syringe from the preset initial pressure. ^ Test pressure, two 201109630 supply to the syringe. At the same time, the fluid supply and supply path are used to measure the residual amount in the syringe and additionally used to supply pressure to the syringe while discharging the glue from the nozzle. Therefore, the supply path is as short as possible in order to minimize the reaction time from the supply pressure to the discharge of the glue from the nozzle. However, if the supply path is too short, the amount of glue contained in the equivalent tester reduces the time required to increase the pressure from the initial pressure to the reference pressure. Therefore, it is difficult to subdivide the time point from the initial pressure to the time period of the reference pressure time point. Therefore, it is difficult to subdivide the value of the amount of residual glue contained in the injector for the time period. SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the problems of the prior art described above, and it is an object of the present invention to provide a device for detecting the amount of residual liquid which minimizes the time required for the supply of liquid to discharge the liquid when discharging the liquid. And more accurately measuring the residual liquid contained in the syringe when measuring the amount of residual liquid. To achieve the above object, the present invention provides a device for detecting the amount of residual liquid comprising a pressure supply unit for supplying a force to the filled liquid The syringe, the first-path injector is incapable of supplying the unit, and the force is applied to the injection n, (10) the body; and the second path, the infusion syringe is more forceful to supply the single core and the transfer pressure to the syringe to make the residual liquid amount. Preferably, the second path is longer than the first path, so when the liquid is discharged by the force, the time from the supply to the discharge of the liquid f is minimized, and when the amount of the liquid is increased, the amount is increased. The time required to change the injection force from the initial ink force to the reference pressure. 201109630 Japanese knife and test pressure required time to the first = consideration "find (four) == for r through the second road _ true charge "= * 4 ' and V ginseng force increase 4, the time required for the test pressure For (9)H2.^, the equation can be satisfied: the amount of liquid in the ejector, and the first reference amount can be the full filling. The reference amount is the amount of liquid in the unfilled liquid of the syringe to switch the first path to the second. Implementing the first path and the device may further comprise: switching unit, routing or switching the second path to the first path, the simple structure of the second path. According to the invention, the device for the amount of liquid remaining contains the transmission force to The second path for discharging the liquid and the second path for detecting the amount of residual liquid is sent to the syringe. (9) Therefore, the length of the first path can be minimized independently of the second path, so that the When the main shot discharges the liquid, the pressure is supplied to the syringe through the first path, and the time required for the liquid to be discharged is minimized. Further, the length of the second path can be maximized independently of the first path, 6 201109630 When the amount of residual liquid in the injection is injected, the pressure is supplied to the injector through the second path, and the time period from the time of the initial pressure to the time of the last pressure and the time point can be subdivided, so that the liquid residue in the syringe can be measured more accurately.

Phoenix...~ Shooting 52' to detect residual liquid & Force Sensing 90 is used to measure the pressure in the syringe 52. The pressure supply unit 60 includes a pressure generator 61, a fixed pressure regulating cry 2, and a valve 63. The pressure generator 61 includes a compressor or a pump and generates a pressure = fixed pressure regulator 62 to regulate the fluid force generated from the pressure generator 61 (4). Valve 63 is used to supply or _ fixed pressure π weeks to benefit 62 to the pressure of the ejector 52. 201109630 The pressure discharge unit 7 releases the pressure from the syringe 52 after supplying the pressure of the discharge glue to the syringe 52, or supplying the pressure to detect the residual amount to the syringe 52. The pressure discharge unit 7A includes a pressure release portion 71 and a valve. Pressure is released. The crucible 71 can include a vacuum generator or a pump. The valve 72 is for discharging or closing the pressure from the syringe 52 to the pressure release portion 71. The first path 80 is coupled to the syringe 52 and the pressure supply unit 6A, and in addition to the syringe 52 and the pressure discharge unit 7A. Similarly, the second path is energized by the syringe 52 and (iv) the supply unit 6G, in addition to the syringe injector and the pressure discharge unit 7G. In this way, the first path 8〇 and the second path 100 are separately provided. When the squeeze injection of the gel + 52 + filled glue is applied and the pressure of the nozzle is discharged from the nozzle to the left lens 52, the first path 8 turns "on" and the second path U00 is closed (see Fig. 4). When the supply is measured to inject a residual gel amount of $52 into the syringe 52, the first path (10) is closed and the second path (10) is opened (see here, the first path 80 is used to transfer the pressure of the discharged glue. To minimize From the time when the pressure supply unit 60 supplies the pressure to the time required to discharge the pressure from the nozzle 53, it is preferable to make the first path 80 as short as possible. Meanwhile, the second path is used to transmit the amount of residual glue. Pressure. In order to lengthen the time required to increase the pressure of the rugged 52 from the initial pressure to the reference repeated force from the pressure supply of the second 6G supply, to allow the subdivision from the time of the initial >1 force to the reference point Preferably, the second path i(10) is longer as long as the time interval between the pressures (4). As a result, the second path 丨(10) is longer than the first path 8〇. m 201109630 Meanwhile, the first path 80 and the second path are just complete Provided independently. However, as shown in FIG. 3, the first path 80 and the second path 1 can be shaped to extend from the pressure supply unit 60 to the path of the syringe 52, so that the first step and the second path are made. 1〇〇 Disagree from the predetermined position and then join each other. In the example, the switching units 1〇1 and 1〇2 for switching the first path 8G or the second path (10), the second path #100 or the first path 80 can provide ^: path 80 and the second path respectively! a position of the divergence, and a position where the first path rib and the path control are engaged with each other. The first path 8〇 and the second path are engaged by the switching grasses 101 and 102, and the pressure supply unit 6〇 and the pressure are discharged. This configuration is simplified compared to the configuration of the first-way (four) and second-path (10) independent. Figure 4 riding 'according to the present invention, according to the above ft supply to the syringe 52 from the syringe For example, when the glue is discharged = the second path touches the edge (4) - _G. Since the first path ratio = = 3.: The pressure generating unit 6 is supplied to the Jing pressure ^ / shooting thief 52 ° in a shorter time, thus minimizing The pressure supply unit 60 supplies the reaction time required to discharge the glue from the nozzle 52 after the pressure is applied. μ 铉 is supplied through the first path 8G, and the pressure is applied to the glue. 6〇: Use the pressure & & pressure discharge unit % path, and pull out the early 70 will be in the syringe 52 U i 201109630 Road ° In order to supply Lili to inject $ 52 to detect the residual glue amount in the syringe 52 '_第-path 8〇, and open the second path · The second path 100 is lighter than the first road 8〇 is still long. Therefore, when comparing the supply pressure through the second path and the supply pressure through the first path 80, the second path takes only 3 long, and the pressure in the note (4) 52 is increased from the city pressure to the parameter = Therefore, the supply pressure to the syringe 52 through the second path can further subdivide the time when the pressure in the syringe 52 is the initial pressure to the time when the pressure in the syringe 52 is the reference pressure. Will explain the supply of pressure to the syringe 52, and take the test diameter _ test: the remaining two: Γ again, will compare with each other using η 52; cup sputum syringe 52 in the amount of residual glue, Assuming the injector force initial pressure P1, the pressure of the measuring syringe 52 is increased from the initial boring tool P1 to the reference pressure P2. Preferably, the reference pressure 't J+ 〇〇 c . It is still small, that is, when the glue starts to discharge from the mouth 53, the pressure of the shot 52 is fed, and the amount of the glue is (4).

Furthermore, the time TC required for the pressure of the enthalpy 52 having the target residual amount QC from the initial slanting to the reference pressure P2 is obtained by the following equation using the previous measurement and the Bayesian 4 'transmission interpolation method. Target residual amount qc. [Equation 1] The target residual amount (QC) is called (TB_TC)/(tb_Ta)}(qaqb)+qb, and the above target residual amount QC is between the first reference amount qa and the third t^QB. The amount can be completely filled with the syringe ±, and the second reference 4 QB is the amount of glue that the syringe 52 is not filled with and is empty. When the syringe 52 is empty, the amount of glue is 〇, and equation i satisfies Equation 2. [Equation 2] Target residual amount (QC) = {(TB-TC) / (TB-TA)} (QA) as /b - come 'if the first reference amount qa is set to glue completely fill the syringe 52, and second When the reference amount QB is set to the time when the syringe 52 is not filled with rubber, the target residual amount qC is always between the first reference amount QA and the second reference QB, and the target residual amount QC is allowed to be measured more simply. , 7 shows the case of using the first path 8 〇 to detect the residual glue amount and the case of using the second path 还 which is longer than the first path 丨〇〇 80 to detect the residual glue amount. In step 11, 'the first path (10) is used to increase the pressure of the syringe 52 filled with the first reference amount of glue from the initial pressure P1 to the reference pressure P2 of 201109630 to be tl 'the first path 8 〇 will be filled with the need === _ pressure p " Zeng Li, reference (four) I for the use of the second path 100 diameter will be filled with a moxibustion to the Q-gel syringe 52 pressure from the initial pressure, the pressure of the township test m gel forest 52 from the secret ^ 2 P2 takes the time t4. Here, as shown in Fig. 7, the reference time between the bucks and the time required from U to Ijt2 is required [Equation 3] (t4 -13) > (t2 - ti) In the case of the pressure to the injection sputum, the pressure in the second path 100 is greater than the first path 8 〇 = residual glue amount, and the pressure in the syringe 52 is increased from the initial pressure ρι to the distance between the temples, which is compared with the first path 80. The second path is 1 〇〇: test [power hit. Since the starting pressure P1 (four) is off reference: more precise subdivision Therefore, more reference quantities can be set in the period of the _ = interval. For example, the information required for each reference amount from the initial pressure of the second reference p2 can be obtained, and the residual amount of the reference pressure of the main target 52 can be more accurately measured. According to the foregoing embodiment of the present invention, the glue applicator is detected. However, the residue according to the present invention is a device for applying a liquid crystal to a substrate, and the liquid:, the liquid can be applied to a process such as an adhesive or a liquid crystal: a conductor m 201109630 as described above, The invention provides a means for producing a residual liquid amount, transporting the pressure of the discharged liquid to the injection (10) first path, and transferring the pressure of the excess amount = the volume to the second path of the device. Therefore, the case where the pressure is transmitted and the liquid is discharged is transmitted through the first-roller wheel pressure, so the reaction time required to supply the pressure to the discharge of the liquid is increased, and the hoof n(4) is increased from the feed. The amount of residual liquid in the syringe can be measured more accurately. The above-mentioned and other objects, features, and social drawings and detailed descriptions of the present invention will be more readily understood, in which the technical spirit of the present invention can be independently described. The coating of the device accompanying °σ is shown in the figure to show that the residual liquid amount can be applied by the present invention.
