Description of the Invention: I: Technical Field of the Invention 3 Field of the Invention The present invention relates to a coating liquid supply for feeding a coating liquid to a die of a coating device such as a table coater 5 Device. BACKGROUND OF THE INVENTION A device for supplying a coating liquid to a mold of a die coater is known as a coating liquid tank containing a coating liquid, and a coating of the above-mentioned coating liquid tank. Liquid, the coating liquid is supplied to a syringe pump of a coating device that relatively moves in a predetermined direction with respect to the table. The setting method of the syringe pump is a fixed type fixed to a position away from the coating device, and a mounting type (m_t) mounted on the coating device and moving together with the mold. In the fixed type, in order to ensure the moving distance of the coating device, the discharge liquid of the coating liquid between the injection pump and the mold 15 is long, and the pressure loss from the injection pipe to the mold is large, and the coating cost is adjusted. The problem of time. In contrast, in the mounting type, since the syringe pump and the coating device move together, the discharge line of the coating liquid between the injection pump and the mold is short, but the suction line between the coating liquid tank and the injection spring is long. The suction time of the syringe pump increases. 2〇Because the mold and the syringe pump are moved at the same time, the weight is heavy, and a large driving force is required, resulting in a large-sized device, and a device for shortening the coating liquid tank and the injection fruit.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and the subject of the present invention is to provide a coating liquid for suction pumping. And the coating liquid supply device having a short discharge time and no air inflow. In order to solve the above problems, the coating liquid supply device of the present invention comprises: a coating liquid tank for accommodating a coating liquid; and a coating liquid for sucking the coating liquid tank, the coating liquid is supplied to be predetermined with respect to the table a syringe pump for coating a mold of a device with a relative movement; and a coating liquid for sucking the coating tank between the coating liquid tank and the syringe pump, and sending the coating liquid to the injection pump a booster pump; the syringe pump is mounted on a side surface of the coating device in a direction perpendicular to a moving direction of the mold. The pressure of the month 1j is preferably a syringe pump driven by an ajr cylinder. 15 The aforementioned syringe pump should be disposed on the aforementioned mold. According to the present invention, since the coating liquid which sucks the coating tank is further provided between the coating liquid tank and the aforementioned syringe pump, the coating liquid is sent out to the boosting pump of the aforementioned syringe pump, so even if the coating liquid tank is The distance between the injection pump is long, and the pressurized liquid can quickly absorb the coating liquid of the coating liquid tank, and supply 20 to the mold through the syringe pump. Since the coating liquid tank is disposed outside the apparatus by this, a sufficient maintenance space can be secured in the apparatus. Furthermore, by the (4) pressurization (9), it is possible to make the pump small and plastic, and at the same time, to miniaturize the device. 6 200900163 Since the syringe pump is mounted on the side of the coating device that forms a right angle with the direction of movement, the syringe pump can be made lower than the mold and no air enters the injection pump. [Implementation of the Cold Type] 5 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Fig. 1 is a flow chart showing the coating liquid supply device of the present invention. The coating liquid tank 1 is for accommodating the coating liquid required for coating, and supplies high-pressure air, and the pressure of the air is pressed, and the coating liquid is extruded from below without using high-pressure air 10 gas, and gravity Extrusion is also possible. The coating liquid tank is connected to the second suction line 3 by a two-way valve, and the third suction line 3 is connected to the pressurized system by a three-way valve 4. . The booster pump 5 is constituted by a syringe pump and is driven by a pneumatic cylinder 6. The booster pump 5 is connected to the second suction line 7 by a three-way valve 4, and the second suction line 7 is connected to the syringe pump 9 by a three-way valve 8. The I5 injection system 9 is driven by a stepping motor. The syringe pump 9 is connected to the discharge line 11 by a three-way valve 8, which is connected to the supply port of the slit die 13 of the coating device 12. As shown in the figure, the coating device 12 has a conventional structure in which the table 14 is relatively moved toward the table 14, and the coating liquid is discharged from the discharge port of the slit die 13, and the substrate 15 on the table 14 is formed into a coating film. 20(a) is a side view showing the positional relationship between the coating liquid supply device and the coating device 12, and Fig. 2(b) is a front view thereof. Here, the two-way valve 2 and the three-way valves 4 and 8 shown in Fig. 1 are omitted. The moving block supporting the both ends of the slit die 13 "relatively moves in the direction of the arrow with respect to the table bucket in a direction perpendicular to the slit of the slit die 13. The side of the moving block 16 which forms a right angle with the moving direction 200900163 side The syringe pump 9 is mounted and disposed under the slit die 13. On the other hand, the pump 5 is disposed together with the coating tank 1 in the tank unit 17 disposed at a position away from the coating unit 12. 1 and the first suction line 3 of the dust pump 5 is disposed in the tank unit 5, 17. The second suction line 7 connecting the booster pump 5 and the syringe pump 9 has a moving block 16 which can only be on the table 14. The length of the stroke is moved, and is supported by an appropriate mechanism to follow the movement of the moving block 16. The discharge nozzle 11 connecting the syringe pump 9 and the slit die 13 is disposed on the moving block 16. Fig. 3 shows the coating liquid supply device A side view showing a modification of the position of the coating device 12 in a ten-line manner. Here, the booster pump 5 is mounted on the side surface of the moving block 16 in a direction perpendicular to the moving direction, together with the syringe pump 9. Therefore, the connection coating The liquid tank 1 and the third section of the Zengxian 5 suction pipeline 3 have a moving block called 堇The length of the stroke is moved on the table 14, and is supported by an appropriate mechanism to follow the movement of the moving block 16. At this time, although the device cannot be miniaturized, 15 can shorten the suction time of the syringe pump 9. The operation of the coating liquid supply device will be described. As shown in the flow chart of Fig. 4, first, high-pressure air is supplied to the coating liquid tank 1 to be pressurized, and the two-way valve is opened (step enough. Then, the pressure chamber 5 is made. The two-way valve 4 is located on the suction side (step is called. Then, the pressure red 6 is located at the pull: 2 〇 sudden call, when the booster pump 5 is retracted, the coating liquid of the coating liquid tank i is read from the double pass 2 The first suction S road 3 is filled with the three-way valve 4, and when the filling of the condensed corn bank pressurization polymer 5 is completed, the three-way chamber 4 is switched to the discharge side two step S4). The second valve is located on the suction side, so that the pressure of the booster pump 5 is located on the pressing side (step is called. Then, the stepping motor is turned to the side of the 200900163 (step S6), and the booster pump 5 The coating liquid is filled from the three-way valve 4 through the second suction line 7 through the three-way valve 8 to the syringe pump 9. When the filling of the syringe pump 9 is completed, The three-way valve 8 is switched to the discharge side (step S7). Then, the stepping motor 10 is rotated to the discharge side (step S8). Thereby, the coating liquid in the syringe pump 9 is discharged from the 5-way valve 8 The pipe 11 is supplied to the slit die 13, and is discharged from the discharge port of the slit die 13 to the substrate 15 of the table 14 to form a coating film. In the above step S7, the three-way valve 8 is switched to the discharge side, and at the same time, the process returns to In step S2, the suction operation of the coating liquid is repeated in the same procedure. Since the booster pump 5 is driven by the pneumatic cylinder 6, the pressure of the booster pump 5 can be controlled by adjusting the pressure of the pneumatic cylinder 610. The second suction line 7 between the booster pump 5 and the syringe pump 9 can be increased. However, when the length of the second suction line 7 is too long, the pressure loss increases and the pressing force of the pneumatic cylinder 6 is insufficient. Therefore, the diameter of the second suction line 7 is increased or the diameter of the pneumatic cylinder 6 is increased. Since the boosting pump 5 is provided in the suction lines 3, 7, even if the coating liquid tank 1 15 and the syringe pump 9 are disposed at a large distance, the coating liquid can be rapidly taken from the coating liquid tank 1 by the booster pump 5. Filled to the syringe pump 9. At the same time, the degree of freedom in the installation position of the coating liquid tank 1 and the syringe pump 9 is wide, and it is provided at an easily accessible position, which is easy to improve the maintainability. Since the coating liquid can be sucked from the coating liquid tank 1 by the suction force of the booster pump 5, 20 the discharge liquid is discharged to the syringe pump 9 by the discharge force of the booster pump 5, so that the coating liquid tank 1 can be added. The pressure is small. For the sake of knowing, the pressing force of the coating liquid tank 1 needs to be 0.5 MPa, and the boosting pump 5 may be added, which may be 0 _2 MPa. Since the syringe pump 9 is disposed on the side of the moving block 16 of the coating device 12, the length of the discharge line from the syringe pump 9 to the slit die 13 can be shortened. By means of 200900163, the pressure loss is reduced and the coating film pressure is easily adjusted. Since the syringe pump 9 is disposed on the side of the moving block 16 of the coating device 12, the injection 9 can be placed under the discharge port of the slit die 13, and the air can be prevented from flowing into the injection even when the coating device 12 is stopped for a long period of time. Pump 9. 5 [Simplified Explanation of the Type] Fig. 1 is a flow chart of the coating liquid supply device of the present invention.
