Description of the Invention: [Technical Field] The present invention relates to a liquid crystal supply device and a method of supplying and collecting liquid crystal. [Prior Art] Fig. 1 is a side view schematically showing a liquid-crystal dispenser and a liquid-crystal-supply unit. As shown in Fig. 1, a liquid crystal coater is installed, and then a clean booth B (also known as a chopper frame) is mounted to place the liquid crystal coater therein. The liquid crystal supply unit is installed outside the clean room B. The liquid crystal coating machine comprises a main frame, a stage 2〇〇 mounted on the main frame 1〇〇, a first guide coupled to the main frame 1〇〇 and placed on both sides of the platform. a guide unit G1, a dispensing-head-unit-support frame 400 coupled to the first guiding unit, and a first driving unit (moving) for moving the coating head unit support frame 400 Unit (not shown), a second guiding unit G2 provided in the coating head unit support frame 4, a plurality of dispensing-head-units 500 coupled to the second guiding unit G2, And a second drive unit (not shown) for moving the coating head unit 5〇〇. As shown in Figs. 1 and 2, each of the coating head units 5A includes a support assembly 51A that connects the second guiding unit G2. A bottle-insertion member 520 is coupled to the support member 51A. A bottle 53 is inserted into the bottle insertion member 52A. The cap (which) 54 is used to close the bottle 530 inlet. A nozzle unit (55) is provided at a lower portion of the support assembly 510. Further, the nozzle connecting tube (n〇zz|e connection U 丨 560) is connected through the cap 54 〇, and the 201131246 liquid crystal in the bottle 〇 53 供应 is supplied to the nozzle unit 550. The cap 540 has an injection passage (H) for injecting liquid crystal. The nozzle unit 550 includes a nozzle 55. One end of the nozzle connecting tube 560 passes through the cap 540 to be positioned near the bottom of the bottle. Reference numeral 570 denotes a connection member (a connector) 0 substrate placed on the stage 2 of the liquid crystal coater. 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, the liquid crystal passes through the nozzle 551 of the nozzle unit 55 to drip onto the substrate. If the amount of liquid crystal contained in the bottle 530 is lowered to some extent, the coating head unit 500 is moved to the liquid crystal supply position. The liquid crystal supply unit includes a liquid-crystal tank 620 installed in a base piate 6i, a pressure-supply unit 630 supplying a pressure to the liquid crystal tank 620, a connection liquid crystal tank 620, and a pressure supply. a connecting pipe of the unit 630, a liquid crystal injection unit (700) passing through the side wall of the clean room B and passing through the side wall, and a pipe connecting the liquid crystal cell 620 and the liquid crystal injection unit 700 A tube 650, and a valve 660 provided to the tube 650, the liquid crystal injection unit 700 includes a base member 720 that couples the wall of the clean room B. An actuator (actuator) 730 is coupled to the base member 720. A guide rail (not shown) is lightly coupled to the actuator 730. A sliding member 740 is slidably coupled to the rail ' and is coupled to the actuator 730. A holder 750 is fixedly attached to the slider 740. A tube support pipe 710 is lightly passed through the holder 750. One end of the tube 650 is connected through the tube support tube 710, and the other end of the tube 650 is connected to the liquid crystal tank 620. 201131246 The actuator 730 moves the slider 740 forward in a state where the coating head 500 moves to the liquid crystal supply position. When the slider 740 moves forward, the holder 750 coupling the slider 740, the tube support tube 71〇 coupled to the holder 75〇, and the tube 650 move forward, and the tube 650 is inserted into the bottle 530. The injection channel η of the cap 540. The valve member 660 is opened, and the pressure supply unit 630 supplies the pressure to the inside of the liquid crystal cell 620, and the liquid crystal stored in the liquid crystal cell 62 is passed through the tube member 65, and is stored in the liquid crystal cell 62 by the pressure supplied to the liquid crystal cell 620. The liquid crystal in the crucible flows through the tube member 650 and is supplied to the bottle through the injection passage of the bottle lid 54. When a predetermined amount of liquid crystal is supplied to the bottle holder 530, the pressure supply unit 63 stops supplying the pressure to the liquid crystal tank 620, and closes. The valve member 66 is so closed that the liquid crystal stored in the liquid crystal chamber 62 is stopped from being supplied to the bottle 530 through the tube 650. . 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 65 is closed from the bottle holder 53. The injection channel η of 540 is removed. The coating head unit 500 is moved to a position where a liquid crystal droplet (a dr〇p 〇f丨丨叩 crystal) is applied to the substrate. As a result, if the amount of liquid crystal supplied to the coating head unit 5 is reduced to a certain extent, the liquid crystal supply unit supplies the liquid crystal to the bottle holder 53. At the same time, when the user desires to change the type of liquid crystal to be discharged to the substrate, the liquid crystal cell 620, the tube member 650, the valve member 660, and other components must be renewed, so that the existing liquid crystal is not mixed with the new type of liquid crystal. Further, if the liquid crystal stored in the liquid crystal cell 620 is used up, the liquid crystal cell 62 must be replaced with a new one. In the case where the tube member 201131246 650 and the valve member 660 and the liquid crystal cell 620 are formed as a single unit, the liquid crystal cell 620, the tube member 650, and the valve member 660 are replaced together.

The second drive unit (not shown). The liquid crystal coater is the same as the liquid crystal coater of the prior art described above. The liquid crystal supply unit includes a liquid crystal tank 620 ′ installed on the bottom plate 610 ′, a pressure supply unit (4) for supplying pressure to the liquid crystal tank _, a connecting tube 640 connecting the liquid crystal tank 62 and the pressure supply unit 630, and a coupling and coupling of the side wall of the clean room B. The liquid crystal injection unit 700, the tube member 650 connecting the liquid crystal cell 620 and the liquid crystal injection unit 7A, and the control unit 8B provided to the tube member 65A. The control unit 800 controls the liquid crystal inflow pipe member 65A. Preferably, the control unit 8 (8) comprises a non-contact type valve which does not contact the liquid in the tube 650 but presses the tube #650 to prevent or allow the liquid crystal to be in the g piece. Flowing in 650. Another embodiment of the control unit 8A can be a contact type valve that is in contact with the liquid crystal in the tube member 65 to prevent the liquid crystal from flowing in the tube member 650. The liquid crystal injection unit τ 700 includes a base member 72 that is coupled to the sidewall of the clean room B. The actuator 73 engages the base member 72〇. The guide rail (not shown) is lightly connected to the actuator no. The slider 740 is slidably coupled to the guide and coupled to the actuator 73A. The holder is fixedly coupled to the slider 740. The tube support tube 71 is coupled through the holder 75A. One end of the official member 650 is connected through the tube support tube 7'', and the other end of the tube member 65'' is connected to the liquid crystal tank 620. 201131246 Further, a sensing unit is provided to detect the liquid crystal in the tube 650. The sensing unit includes a first sensor 910 and a second sensor 920. The first sensor 910 is provided on the tube 650 adjacent to the liquid crystal injection unit 700. The second sensor 920 is provided on the tube 650 adjacent to the liquid crystal cell 620. . The first sensor 910 is placed at a position where the liquid crystal is discharged to the bottle holder 53, and the second sensor 920 is placed at a position where the liquid crystal is discharged from the liquid crystal cell 62. The first sensor 910 and the first sensor 920 each include a light emitter and a light receiver. The light emitter emits light and the light receiver receives light. Based on the amount of light received, it is determined whether or not liquid crystal is present in the tube 650. 4 is a flow diagram of a method of supplying and collecting liquid crystals in accordance with an embodiment of the present invention. As shown in FIGS. 3 and 4, the method of supplying and collecting liquid crystal according to an embodiment of the present invention includes a liquid crystal supply step, a liquid crystal stop supply step, a liquid crystal collection step, and a decision step. The liquid crystal supply step ' supplies pressure to the liquid crystal cell 620, and causes the liquid crystal stored in the liquid crystal cell 620 to flow through the tube member 650 to the bottle 530. In the liquid crystal stop supply step, when a predetermined amount of liquid crystal is supplied to the bottle 530, the supply of liquid crystal to the bottle 530 through the tube 650 is stopped. At the liquid crystal stop supply step, the supply pressure is stopped to the liquid crystal cell 620, and the control unit 800 provided to the tube member 650 is closed, thereby stopping the supply of the liquid crystal to the bottle holder 530 through the tube member 65. . In the liquid crystal collection step, the liquid crystal in the tube 650 is collected into the liquid crystal cell 620. According to an example in which the liquid crystal in the tube member 650 is collected into the liquid crystal cell 620, the inside of the liquid crystal cell 620 is at atmospheric pressure, and the control unit_opened to be provided to the tube member 650 allows the tube member 650 to communicate with the liquid crystal cell 620 because Gravity allows the liquid crystal in the tube 650 to flow into the liquid crystal cell 62. 201131246 If the pressure supplied from the pressure supply unit 630 is blocked to the liquid crystal cell 62, the liquid crystal cell 620 can be returned to the atmospheric pressure condition. However, in order to rapidly lower the internal pressure of the liquid crystal cell 62'' to the atmospheric pressure, the liquid crystal cell 62' may have a pressure reducing valve (not shown) or a pressure regulating pump (not shown). In the determining step, after the liquid crystal in the tube 650 is collected into the liquid crystal cell 620, it is determined whether any liquid crystal remains in the tube 650. Preferably, the sensor is used to detect whether there is liquid crystal residue in the tube member 650. If the sensor detects liquid crystals, it is determined that there is liquid crystal residue in the tube 650. Conversely, if the sensor does not detect the liquid crystal, then it is determined that there is no liquid crystal residue in the tube 650. Preferably, the liquid crystal in the tube 650 is detected at two locations of the tube 650. One of the two places of the tube 650 is a place where the liquid crystal is discharged to the bottle holder 53 ,, and the other place is a place where the liquid crystal is discharged from the liquid crystal cell 620. The operation and effects of the liquid crystal supply device and the method of supplying and collecting liquid crystal according to an embodiment of the present invention will be described later. If the amount of liquid crystal contained in the bottle 530 of the coating head unit 500 is lowered to a predetermined extent, the coating head unit 500 is moved to the liquid crystal supply position. In a state where the coating head unit 500 has moved to the liquid crystal supply position, the actuator 730 moves the slider 740 forward. When the slider 74 is moved forward; ^ is slidable; the 74 支 750, the tube support tube 71 耦 coupled to the 750, and the tube 650 are moved forward, and the tube 65 is inserted into the bottle The injection channel η of the cap 540 of the device 53. The control unit 800 is now opened, and the pressure supply unit 63 〇 supplies pressure to the inside of the liquid crystal cell 620, and the liquid crystal stored in the liquid crystal cell 62 is caused to flow through the tube member 650. The liquid crystal stored in the liquid crystal cell 62A is supplied to the bottle 201131246 530 through the injection channel 管 of the tube 650 and the cap 540 by the pressure supplied to the inside of the liquid crystal cell 62. When a predetermined amount of liquid crystal is supplied to the bottle 530, the pressure supply unit 63 stops supplying the pressure to the liquid crystal cell 620, and closes the control unit 8〇〇, thereby stopping the supply of the liquid crystal stored in the liquid crystal cell 62〇 through the tube 650 to Bottle 530. The actuator 730 moves the slider 74A backward. When the slider 74 is moved backward, the holder 750 coupled to the slider 740, the tube support tube 710 coupled to the holder 750, and the tube 650 are moved backward, and the tube 65 is removed from the bottle of the bottle holder 53. The injection channel η of the cover 540 is removed. The coating head unit 500 is moved to a position where the liquid crystal is to be dropped to the substrate. As a result, if the amount of liquid crystal supplied to the bottle 530 of the coating head unit 500 falls to a predetermined level, the liquid crystal supply unit supplies the liquid crystal to the bottle 530. ^At the same time, if the liquid crystal type to be discharged to the substrate is changed, the liquid crystal cell 62〇, the official member 650, the control unit 8〇〇, and other components must be replaced. If the tube member 6沁 and the control unit _ can be separated from each other, then only ride The crystal bath_ and the tube 650 are replaced with new ones. When the liquid crystal cell 620, the tube member 650, and the control unit 8 are replaced with new ones, the liquid crystal remaining in the tube member 650 is first collected to the liquid crystal cell 62'. Then, the liquid crystal in the tube member 65 is collected into the liquid crystal cell 62 by the following method. First, the inside of the liquid crystal cell 620 is made to communicate with the atmosphere, and the liquid crystal cell 62 is turned inside. P is at atmospheric pressure. Further, the control unit 800 provided to the tube member 65A is opened to open the official member. Because of its own weight, the liquid crystal contained in the tube member 650 flows downward through the tube member (10), and the liquid crystal chamber 620. The sensing unit of the official member 650 is for detecting liquid crystal which is not collected in the liquid crystal and remains in the tube 65〇. If the sensing unit detects the 201131246 liquid crystal, it transmits a signal to the control unit of the liquid crystal coating machine. In this case, the tube 65G cannot be replaced. If there is no liquid crystal remaining in the tube member 650, the tube member 65A inserted into the tube supporting tube 71 of the liquid crystal injection unit 700 is pulled out, and the tube member 650 is removed from the tube supporting tube 710. Next, a new tube is inserted into the tube support tube 710. When there is liquid crystal residue in the right official member 650, the liquid crystal remaining in the tube member 65 is removed, and the tube member 65 which is inserted into the tube supporting tube 71 of the liquid crystal injection unit 7 is pulled out, so that the tube member 65 is supported from the tube member. The tube 71 is removed. Next, the new B piece is inserted into the official piece 胄 710. The method of removing the liquid crystal from the tube (10) can be carried out in various ways. According to the present invention, when the liquid crystal cell 62G, the tube member (four), and the replacement device (4), the tube member (4) is cut into the liquid crystal to receive the liquid crystal cell member (4), whether there is a liquid crystal residue ' _ 'If the tube member 650 is left in the crystal, the liquid crystal cell (10), the tube member 65〇, and the control unit 70 „ replaced with a new one. Therefore, when the liquid crystal cell 62〇, the tube 650, and the = new, the liquid crystal does not fall to the liquid crystal coater, the liquid crystal liquid crystal The second SC liquid sample is retained and then, if there is no liquid crystal residue in the pipe, the simple liquid crystal will not be lost. ^^^ When the fine material is to be picked, the coating machine, the clean room, the floor, etc. BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and other objects, features, and advantages of the present invention will be apparent from the accompanying drawings and detailed description accompanying the description of the accompanying drawings.
