A bottle-insertion member 520 is coupled to the support assembly 510. The bottle 530 is inserted into the bottle insert member 520. A cap 54 is coupled to the mouth of the bottle 530 to close the inlet of the bottle 530. A nozzle unit 55 is provided on the lower portion of the support assembly 51. Further, the 'nozzle connection tube' e) 560 is connected through the 201143907 cap 540, thereby supplying the liquid crystal in the bottle 530 to the nozzle unit 550. The cap 540 has an injection passage H. The nozzle unit 550 includes nozzles 55 and sensors (not shown) respectively provided at the upper and lower portions of the crotch side surface of the bottle holder 53. The liquid crystal supply unit includes a liquid-crystal tank 620 installed in a base plate 610, a pressure-supply unit 630 that supplies a pressure to the liquid crystal tank 620, a connection liquid crystal tank 620, and a pressure supply unit. a connection pipe 64 630 of the 630, a liquid-crystal-injection unit 700 connected to the side wall of the cover frame b, a tube 650 connecting the liquid crystal cell 620 and the liquid crystal injection unit 700, and A valve 8 提供 is provided to the tube 650. The valve member 800 controls the flow of the liquid crystal to the tube member 65A. The liquid crystal injection unit 700 includes a base member 720 coupled to the wall of the cover frame B. An actuator 730 is coupled to the base member 720. A guide rail (not shown) is lightly coupled to the actuator 730. A siiding member 740 can slidably couple the guide and connect the actuator 730. A holder 75 is fixedly coupled to the slider 740. A tube support pipe 71 is coupled through the holder 750. One end of the tube member 650 is connected through the tube support tube 71, and the other end of the tube 650 is connected to the liquid crystal chamber 620. The liquid crystal coater and the liquid crystal supply unit operate as follows. The substrate is placed on the platform 2 of the liquid crystal coater. The first driving unit and the second driving unit move the coating head unit 500 from the initial position to the liquid crystal coating position. The first driving unit and the second driving unit move the coating head unit 500 according to preset data. When the coating head unit 5 (8) moves, a predetermined amount (precjetermine (j amount) of liquid crystal of 201143907 is applied to the substrate through the nozzle 551 of each coating head unit 500. The substrate is divided into unit panels, and a predetermined amount of liquid crystal is applied. To each unit panel, the sum of the amounts of liquid crystals applied to the individual unit panels is equal to a predetermined amount of liquid crystal applied to the substrate. After applying a predetermined amount of liquid crystal to the substrate, the first driving unit and the second driving unit move the coating head unit 500. To the initial position, the substrate disposed on the platform 200 is replaced with a new substrate. After the new substrate is placed on the platform 200, the first driving unit and the second driving unit move the coating head unit 500 to the liquid crystal coating position to apply the liquid crystal to The first driving unit and the second driving unit move the coating head unit 500 according to the preset data. When the coating head unit 5 moves, a predetermined amount of liquid crystal is applied through the nozzle 551 of each coating head unit 500 to Substrate After coating a predetermined amount of liquid crystal to the substrate, the coating head unit 5 (8) is moved to the initial position. The substrate placed on the stage 200 is replaced with a new one. A predetermined amount of liquid crystal is applied to the plurality of substrates. After the liquid crystal coater applies a predetermined amount of liquid crystal to each of the substrates, the amount of liquid crystal applied through the nozzles 551 of the coating head unit 500 is measured. Generally, the coating is scheduled. After the liquid crystal was applied to each of 2G or 25 substrates, the amount of liquid crystal applied through the nozzle 551 of the coating head single = 500 was measured, and measured by a measuring unit 11 〇 mounted on the liquid crystal coater. The amount of liquid crystal. After each coating head unit 2 500 is moved to the position where the measuring unit 11 is mounted, the nozzle 551 of the coating head unit applies liquid crystal to the measuring unit 11A, and measures the amount of liquid crystal. The amount of liquid crystal measured by the unit 110 is within the reference range, and the coating head is moved to the liquid crystal coating position to apply the liquid crystal to the substrate. The amount of liquid crystal measured by the detecting unit 110 is not in the reference range. Inside, the "out" is adjusted so that the amount of liquid 201143907 coated by the nozzle 551 of the coated head grass is 551 within the reference range. Then the coating head unit 5 is moved to the liquid crystal coating. The liquid crystal contained in the cloth bottle 530 is lowered to a certain extent, and is provided at = stop The nozzle 551 of the coating head unit 5 is coated with a liquid crystal at the base. Next, the coating head unit 500 is moved to a position where the liquid crystal is supplied. When the coating head unit is moved to the ship crystal supply position, the liquid crystal supply unit supplies the liquid crystal. To the bottle 530 of the coating head unit 5 . The liquid crystal supply unit _ machi program supplies the bottle 530 of the liquid crystal head unit 5 。. First, the actuator 730 moves the slider 740 forward. When the slider 740 is directed The front movement and the support 750 coupling the slider 740, the tube support 710 coupling the holder 750, and the tube 650 are moved forward, and the tube 65 is inserted into the injection passage of the cap 540 of the bottle 530. η. The valve member 800 is opened and the pressure supply unit 63 is supplied with pressure into the inside of the liquid crystal cell 620, so that the liquid crystal stored in the liquid crystal cell 62 is passed through the tube member 65. The liquid crystal stored in the liquid crystal cell 62 is transported through the tube 650 and the injection channel 瓶 of the cap 540 to the bottle 530 by the pressure supplied to the inside of the liquid crystal cell 620. When the liquid crystal supplied to the bottle 530 reaches a predetermined level, the pressure supply unit 630 stops supplying the pressure to the liquid crystal cell 620, and the valve member 800 is closed, thereby stopping the supply of the liquid crystal through the tube 650 stored in the liquid crystal cell 620 to the bottle 530. . Actuator 730 moves slider 740 rearward. When the slider 740 moves backward, the holder 750 coupled to the slider 740, the tube support tube 710 coupled to the holder 750, and the tube 650 move backward, and the tube 650 is removed from the bottle 530 by the 201143907 cap 540. The injection channel η is removed. When the liquid crystal is supplied to the bottle 530 of the coating head unit 500, the coating head unit 500 is moved to the liquid crystal coating position. ^ As a result, if the liquid crystal supplied to the bottle 530 of the coating head unit 500 is lowered to some extent, the coating head unit 5 is moved to the liquid crystal supply position, so that the liquid crystal supply unit supplies the liquid crystal to the coating head unit. 5〇〇. However, the liquid crystal coater and the liquid crystal supply unit which operate as described above have problems with y. That is, when the liquid crystal contained in the coating head unit bottle holder 53G is lowered to a certain extent, the liquid crystal supply unit supplies the liquid crystal to the bottle 530. Therefore, if the coating head unit 500 moves according to the preset data and applies a predetermined amount of liquid crystal to the substrate through the nozzle 551 of the coating head unit 500, the amount of liquid crystal contained in the viewer 530 is reduced to a certain extent. Then, the nozzle 551 of the coating head unit 5 stops coating the liquid crystal to the substrate, and then the coating head unit is moved to the liquid crystal supply position = the liquid crystal is supplied to the coating head unit to leak. Therefore, since the liquid crystal is supplied to the bottle wo during the application of the prepreg aa to the substrate, it takes a long time to apply a predetermined amount of liquid crystal to the substrate.

First, it is explained that after the predetermined amount of liquid crystal has been applied to the substrate S disposed on the stage 2, and then the substrate s on the stage 2 is replaced with the new substrate s, the replaced substrate S is being placed on the stage 200. At this time, each of the coating head units 5 is moved to the liquid crystal supply position, so that the liquid crystal supply unit supplies the liquid crystal to the bottle 530. ° ^ After a predetermined amount of liquid crystal has been applied to the substrate s disposed on the stage 200, and then the liquid crystal-coated substrate S is replaced with another substrate §, when the replacement substrate S is being placed on the stage, the liquid crystal is supplied The fresh element supplies the liquid crystal to the bottle 530 of each of the f-head units 500. If the liquid crystal supplied to the coater unit 5 of the coating head unit 5 reaches a predetermined level, the supply of the liquid crystal is terminated. If the liquid crystal supplied to the bottle holder 53 () has not reached the pre-filament degree when the replaced substrate s is placed on the platform, the liquid crystal of the segment coffee 530 reaches a predetermined level, or is disposed on the replaced substrate S. The supply of the liquid crystal can be terminated at the time of the flat 200. The liquid crystal is supplied to the bottle 530 < 'the first purchase unit and the second transfer unit chicken coating position of each of the coating head units 500. The first driving unit and the second driving unit move the coating 根据 according to the preset data. When the coating head unit ' moves along the predetermined path, a predetermined amount of liquid crystal is applied to the substrate 1 through the nozzle 551 of the P ^ head unit 5 〇 0. After a predetermined amount of liquid crystal has been applied to the substrate s, the substrate 13 1 201143907 s disposed on the stage is replaced with another substrate s' and the replaced substrate s is placed on the stage 2 。. During the replacement of the substrate S, the first driving unit and the second driving unit move the coating head unit 500 to a position where the liquid crystal supply unit supplies the liquid crystal. By repeating the above procedure, a predetermined amount of liquid crystal can be applied to each of the plurality of substrates, and the liquid crystal can be supplied to the bottle holders 53 of the respective coating head units 5A. At the same time, the time during which the liquid crystal is supplied to the bottle holder 53 of each of the coating head units 500 can be variably set by the user. First, each time the liquid crystal-coated substrate S is replaced with another substrate S and placed on the stage 200, the liquid crystal can be supplied to the bottle 530 of each of the coating head units 5''. That is, the liquid crystal supply time can be set such that when a predetermined amount of liquid crystal has been applied to the substrate S, and the substrate S is replaced with another substrate s and placed on the stage 200, liquid crystal is supplied to each of the coating head units 5 (^ The liquid crystal supply time may also be set to be repeated during the above process, after the mth coating liquid crystal is applied to the substrate s disposed on the platform, when the substrate s is replaced with another substrate S and placed on the platform 2〇〇, The liquid crystal is supplied to each of the coating head units 500, where m is a multiple of a specific integer preset by the user, for example, a specific integer is 2 or 3' or any number that can be determined by the user such as 3, 5, 7...). ★ If the mth time preset by the user is a multiple of 3, for example, when the 3rd, 6th, 9th, etc. are placed on the platform and the liquid crystal substrate s is replaced with another new substrate S is placed on the bottle 530 when placed on the platform. At the same time, if the liquid crystal is being applied to the substrate S disposed on the platform not to be multiples of 3 (for example, the fourth or fifth base fs placed on the platform), the lang or similar device side to the bottler 53G When the stored liquid crystal is preset with less money (4), when Congjia replaces the substrate s with another substrate s and places it on the platform, the liquid crystal is supplied to the bottle holder 53. 201143907 Next, a case where the respective coating head units are moved to the liquid crystal supply position and the liquid crystal supply unit supplies the liquid crystal to the bottle 530 when measuring the amount of liquid crystal applied through the nozzles 551 of the coating head unit 500 will be described. The substrate S to which the liquid crystal has not been applied is placed on the stage 2' of the liquid crystal coater. As shown in FIG. 6, after a predetermined amount of liquid crystal is applied to the substrate s by the liquid crystal coater, the head unit 500 is moved to the upper side of the measuring unit 11 to measure the coating through the nozzles 551 of the respective coating head units 500. The amount of liquid crystal. Preferably, each of the measuring units 110 is installed below a position where the liquid crystal is supplied to the coating head unit 5''. The amount of liquid crystal applied through the nozzle 551 of the coating head unit 5 is measured by the measuring unit 11〇. When the amount of liquid crystal applied through the nozzle 551 of the coating head unit 5 is measured by the measuring unit 11, the liquid crystal supply unit supplies the liquid crystal to the bottle 530 of the coating head unit 500. Here, in addition to the operation of measuring the amount of liquid crystal applied through the nozzle 551 of the coating head unit 500 after a predetermined amount of liquid crystal has been applied to the substrate s, the substrate s to which the liquid crystal has been applied can be replaced with another substrate. The operation of s. After the amount of liquid crystal applied through the nozzle 55 of the coating head unit 5 is measured, the first driving unit and the second driving unit move the coating head unit 5 to the liquid crystal application position. The first driving unit and the second driving unit move the coating head unit 500 according to the preset data. When the coating head unit 500 moves along the predetermined path, a predetermined amount of liquid crystal is applied to the substrate s through the nozzles 551 of the respective coating head units 500. After the pre-coating liquid is applied to the substrate § day, the first driving unit and the second driving unit move the coating head unit 500 over the measuring unit 11A, and replace the substrate S disposed on the platform 200 with Another new substrate s. When the above procedure is repeated for each substrate S to which the liquid crystal is to be applied, the liquid crystal coating layer coats a predetermined amount of liquid crystal to each of the plurality of substrates s. During the repeating process period 201143907, the liquid crystal material is measured through the nozzle 551 of the coating head unit, and the briquettes are supplied to the coating unit 5 瓶 at the same time as the θ. The liquid crystal 罝 'coated by the nozzle 551 and the operation of supplying the liquid crystal to the coating head unit bottle 520 when measuring the amount of liquid crystal may be performed every time the liquid crystal is applied to the substrate §, or may be It is executed after the predetermined amount of the liquid crystal user has been applied for the mth time to be placed on the substrate S of the platform 200. Even after a predetermined amount of liquid crystal has been applied to the substrate s on the platform 2GG which is not the user's preset mth time, the liquid crystal coated by the nozzle 551 of the element 500 can be measured if necessary. The amount of operation. In this case, liquid crystal is not supplied to the bottle 530 of the coating head unit 5 when the liquid crystal amount is equivalently measured. At the same time, if the liquid crystal is being applied to the substrate s disposed on the platform 200 that is not preset by the user, the sensor or the like detects that the liquid crystal stored in the bottle holder 53 is a preset amount or less. At a predetermined amount, it is preferred to supply the liquid crystal to the bottle 530 after a predetermined amount of liquid crystal has been applied to the relevant substrate S. After a predetermined amount of liquid crystal is applied to the substrates by the liquid crystal coater, the liquid crystal coater is inspected and repaired. When the liquid crystal coater is inspected and repaired, the substrate S is not supplied to the liquid crystal coater under inspection and maintenance, but is supplied to the liquid crystal coater at the next position. When the liquid crystal coater is repaired, the liquid crystal supply unit can supply the liquid crystal to the bottle 530 of the coating head unit 500. The substrate S is placed on the stage 2 after the liquid crystal coater has been repaired. The first driving unit and the second driving unit move the coating head unit 5 to the liquid crystal coating position. The first driving unit and the second driving unit move and coat the 201143907 head unit 500 according to the preset data. When the coating head unit 500 moves along the predetermined path, a predetermined amount of liquid crystal is applied to the substrate s through the nozzles 551 of the respective coating head units 500. When the predetermined amount of liquid crystal has been applied to a plurality of substrates, the liquid crystal coater is inspected and repaired. That is, the liquid crystal coater can be inspected and repaired periodically. At the same time, the liquid crystal supply unit supplies the liquid crystal to the bottle 530 of the coating head unit 500 by the following procedure. First, the actuator 730 moves the slider 740 forward. When the slider 740 moves forward, the holder 750 coupling the slider 740, the tube support tube 710 coupling the holder 750, and the tube 650 move forward, and the tube 65 is inserted into the bottle of the bottle 530. The injection channel 盖 of the cover 540. The valve member 800 is opened and the pressure supply unit 630 supplies pressure to the inside of the liquid crystal cell 620' so that the liquid crystal stored in the liquid crystal cell 62 is caused to flow through the tube member 65A. By the pressure supplied to the inside of the liquid crystal cell 620, the liquid crystal stored in the liquid crystal cell 620 is supplied to the bottle 530 through the injection passage η of the tube 650 and the lid 540. 当 When the liquid crystal supplied to the bottle 530 reaches a predetermined level The pressure supply unit 630 stops the supply pressure to the liquid crystal cell 620, and the valve member 8 is closed, thereby stopping the supply of the liquid crystal through the tube 650 stored in the liquid crystal cell 620 to the bottle 530. Actuator 730 moves slider 740 rearward. When the slider 740 moves backward, the holder 750 coupled to the slider 740, the tube support tube 710 coupled to the holder 750, and the tube 650 move backward, and the tube 650 is removed from the cap 540 of the bottle 530.

That is, a liquid crystal supply unit supplies liquid crystal to the bottle holder of a coating head unit. If the number of liquid crystal supply units is smaller than the number of the coating head units 5, the liquid crystal supply unit alternately supplies liquid crystals to the individual bottle states 530 of the coating head unit 5''. For example, as shown in FIG. 7, it is assumed that there are 6 coating head units $(9) and 3 liquid crystal supply units, and when the coating head unit 5 is moved to the first liquid crystal supply position, '3 liquid crystal supply units A bottle 530 that supplies liquid crystal to an odd coating head unit 5 〇〇 > Next, as shown in Fig. 8, when the coating head unit 5 is moved to the second liquid crystal supply position, the three liquid crystal supply units supply the liquid crystal to the bottle 530 of the even coating head unit 500. At the same time, for example, after the final measurement of the amount of liquid crystal applied through the nozzle, and then the amount of liquid crystal applied to the substrate S is repeated (for example, 2 〇 or 25), the measurement is performed by the nozzle 551 of the coating head unit 500. The amount of liquid crystal. If the amount of liquid crystal measured by the measuring unit 110 is within the reference range, the coating head unit 500 is moved to the liquid crystal coating position to apply the liquid cup ^ while 'the amount of crystal is measured by the unit 11G amount. In the reference ^, the outflow amount is adjusted so that the liquid crystal I coated through the nozzle 551 of the coating head unit 5 is within the reference range, and then the coating head unit 500 is moved to the liquid crystal coating position. When the liquid crystal supplied to the coating head unit 5 is reached to a predetermined extent, the sensor provided to the bottle 530 detects the amount of liquid crystal. Control single crystal supply single series silk ship ^ early 疋 make liquid. = When the liquid crystal stored in the liquid crystal cell 620 of the liquid crystal supply unit is lowered to a certain t degree, the control unit performs the 4 measurement and (4) the control unit picks up the alarm to display the early element. The officer replaces the liquid crystal cell 620 with a new liquid crystal cell. The effect of supplying the liquid crystal to the liquid crystal coating machine according to the present invention is as follows. 201143907 According to the present invention, when the substrate s disposed on the stage 200 is replaced with the new substrate S, the coating head unit 500 is moved to the liquid crystal supply position so that the liquid crystal supply is supplied. The unit supplies liquid crystal to the bottle 530 of the coating head unit 5〇〇. According to the present invention, liquid crystals can be supplied from the liquid crystal supply unit to the bottle 530 of the coating head unit 5 每 every time the substrate S disposed on the stage 200 is replaced with a new substrate s. Furthermore, whenever the substrate s corresponding to the preset number of times placed on the platform is replaced with a new substrate, the liquid crystal can be supplied when the substrate s is replaced. According to the present invention, when the amount of liquid crystal applied through the nozzle 551 of the coating head unit 5 is equivalently measured, the liquid crystal can be supplied from the liquid crystal supply unit to the bottle 530 of the coating head unit 500. According to the present invention, when the liquid crystal coater is inspected and repaired, the liquid crystal supply unit can supply the liquid crystal to the bottle 530 of the coating head unit 5''. In this way, according to the present invention, when the substrate s placed on the stage 2 is replaced with a new substrate s, or when the amount of liquid crystal applied through the nozzle 551 of the coating head unit 5 is measured, or inspection and maintenance are performed In the liquid crystal coater, the liquid crystal is supplied to the bottle 530 of the coating head unit 500. Conventionally, if the liquid crystal of the bottle 530 is exhausted during the process of applying a predetermined amount of liquid crystal to the substrate s, the procedure of applying the liquid crystal to the substrate s must be stopped, and the liquid crystal coating process is delayed. However, according to the present invention, the bottle 530 supplying the liquid crystal to the coating head unit 5 is inevitably stopped when the liquid crystal coating process is stopped, for example, when the substrate S disposed on the stage 200 is replaced with the new substrate S' or The amount of liquid crystal applied by the nozzle 551 through the coating was measured. For this reason, when the bottle holder 53 has a predetermined amount or more of crystallizing, and the liquid crystal is not applied to the substrate s, the liquid crystal coating process is stopped in order to supply the liquid crystal to the bottle 530. From this point on, it is possible to reduce the time required for the coating machine to apply a predetermined amount of liquid horse to each substrate 201143907. As described above, the present invention provides a method of supplying a liquid crystal to a liquid crystal coater, when replacing a substrate disposed on a stage with a new substrate, or measuring a liquid crystal amount applied through a nozzle of the coating head unit, Alternatively, the liquid crystal coater 4 is inspected and repaired, and the liquid crystal is supplied to the bottle holder of the coating head unit. Therefore, the bottle holder always has a predetermined amount of liquid crystal, thereby preventing the liquid crystal coating process from being stopped in order to supply the liquid crystal to the bottle when the liquid crystal 4 is applied to the substrate through the nozzle of the coating head unit. Thereby, the time during which the liquid crystal coater applies a predetermined amount of liquid crystal to each substrate is reduced. BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will become more apparent from 2 is a flow chart showing a method of supplying a liquid crystal to a liquid crystal coater according to an embodiment of the present invention; and FIGS. 3, 4, and 5 are plan views showing a procedure of supplying a liquid crystal to a liquid crystal coater according to an embodiment of the present invention; It is shown that when measuring the liquid crystal 4 coated through the nozzle f of the coating head unit of the liquid crystal coater, 'there will be the supply of the bottle to the coating head unit, and FIGS. 7 and 8 show the supply of liquid crystal to A plan view of the procedure of the coating head single bottle of the liquid crystal coater.
