More specifically, the present invention uses a metering pump such as a Mohno pump that precisely adjusts the amount of the chemical liquid discharged and enables a fixed amount of the liquid to be discharged, and furthermore, the pressure of the air supplied to the spray nozzle is precisely A sine wave caused by an external pump is prevented from being generated in the air pressure forming process, thereby preventing shaking in chemical liquid discharge and deterioration of coating quality of the chemical liquid or occurrence of defects To a spraying system for precise ejection of a chemical liquid capable of controlling various doses of a chemical liquid and capable of providing various spray sequences, and a spray pattern printing apparatus having the spray system.

Generally, in order to manufacture parts of FPD or FPD such as PDP panel, LCD panel, or organic EL panel such as OLED (organic light emitting device), a substrate or a work piece such as glass, A pattern such as R, G, or B pixels should be formed on the surface of the substrate. As one of such pattern forming apparatuses, in the prior art, a chemical liquid is ejected onto a printing roll by using a spray apparatus that ejects a photoresist (PR) liquid or a metal paste (hereinafter, referred to as a "chemical liquid" Thereafter, the printing roll is moved on the substrate and transferred to form a pattern on the substrate.

In the above-described pattern printing apparatus, for example, a spray type pattern printing apparatus for discharging a chemical liquid on a printing roll by a spraying method is used.

Fig. 1A schematically shows a cross-sectional side view of a spray pattern printing apparatus according to the prior art, and Fig. 1B schematically shows a front cross-sectional view of a spray pattern printing apparatus according to the prior art shown in Fig. 1A 1C is a diagram specifically showing a chemical solution spraying system used in a pattern printing apparatus of a spraying method according to the prior art.

1A to 1C, a spray type pattern printing apparatus 100 according to the related art includes a printing roll 110 having a pattern 112 to be printed on a substrate 150; A chemical solution spraying system (121) for spraying a chemical solution on the pattern (112) of the printing roll (110); A gantry 146 for supporting the printing roll 110 so as to be rotatable and liftable; A pair of LM guides 148 to which the gantry 146 is mounted and moves the printing roll 110 forward and backward to transfer the pattern 112 onto the substrate 150; A main frame 190 on which a stage 170 supporting the substrate 150 is placed; And an alignment system 180 for supporting the stage 170 and controlling the alignment of the X-axis, Y-axis, and? -Axis of the stage 170.

Referring to FIG. 1C, a chemical solution spray system 121 according to the related art includes a chemical solution supply device 120 for supplying a chemical solution; A spray nozzle 125 connected to the chemical solution supply device 120 through a chemical solution supply path 122 and spraying the chemical solution onto the printing roll 110; An air supply device 130 for supplying air to the chemical liquid supply device 120 and the spray nozzle 125 through a common air supply path 131 and a plurality of air flow paths 136a, 136b and 136c; A plurality of pneumatic regulators provided on the plurality of air branch paths 136a, 136b and 136c for controlling the pressure of the air supplied to the chemical liquid supply device 120 and the spray nozzles 125, respectively; : 132a, 132b, 132c); (132a, 132b, 132c) and the chemical liquid supply device (120) and the spray nozzle (125) on the plurality of air branch paths (136a, 136b, 136c) 134b, 134c that are controlled to regulate the supply of air on air baffles 136a, 136b, 136c of air baffles 136a, 136b, 136c. Here, the plurality of valves 134a, 134b, and 134c may be implemented by, for example, a solenoid valve.

The chemical liquid spraying system 121 used in the apparatus 100 for spraying patterning according to the related art uses the air pressure supplied from the air supplying device 130 to inject the chemical liquid of the chemical liquid supplying device 120 into the spray nozzle 125, and at the same time, the air pressure is directly applied into the spray nozzle 125 to adjust the injection pressure of the chemical liquid in the spray nozzle 125 to inject the chemical liquid.

However, the following problems arise in the chemical solution spraying system 121 and the spraying pattern forming apparatus 100 having the conventional art described above.

1. A plurality of pneumatic controllers 132a, 132b and 132c used in the chemical solution spraying system 121 control the pressure of the air supplied from the air supply device 130 in a manual control manner. Such a manual control method is less accurate in air pressure control, and therefore, it is difficult to control the air pressure uniformly.

2. When a plurality of pneumatic controllers 132a, 132b and 132c are used, the air pressure containing the sine wave already generated in the external pump at the time of forming the air pressure is supplied to the chemical liquid supply device 120 and the spray nozzle 125 ). Therefore, not only the chemical liquid supplied from the chemical liquid supply device 120 to the spray nozzle 125 can not be supplied in a certain amount but also the chemical liquid ejected from the spray nozzle 125 is shaken.

3. Due to the above-described problems 1 and 2, the coating quality of the transferred chemical liquid on the substrate 150 may ultimately be deteriorated or defective.

4. Further, since the plurality of pneumatic controllers 132a, 132b, 132c are controlled in a manual manner, it is impossible to change the supply amount of the chemical liquid supplied from the chemical liquid supply device 120 to the spray nozzle 125, for example. The chemical liquid spraying system 121 and the spray patterning apparatus 100 having the chemical liquid spraying system 121 according to the related art can be used when a different amount of chemical liquid injection is required depending on the pattern 112 on the printing roll 150 (For example, when the amount of the chemical liquid to be injected to the different pattern 112 is different), or when different air pressures are required for the chemical liquid injection (when different liquids of viscosity are used, etc.).

Therefore, there is a need for a new method for solving the problems of the above-described conventional techniques.
