Description of the Invention: _ Technical Field of the Invention The present invention relates to a coater for discharging liquid crystals to a panel region defined on a mother substrate. [Prior Art] Liquid crystal is an intermediate phase between a crystalline solid and an isotropic liquid, and combines some characteristics of a crystal structure and a deformed fluid. Liquid crystal displays (LCDs) utilize the anisotropy associated with the fluidity and crystallization characteristics of liquid crystal parameters. Liquid crystal displays are used in mobile phones, portable computers, desktop monitors, and LCD TVs. The liquid crystal display is composed of a TFT array substrate, a color filter array substrate, and a liquid crystal layer interposed therebetween. By controlling the voltage applied to the liquid crystal layer of each pixel, different amounts of light can be allowed to pass, and different degrees of gray scale are formed.液晶 The liquid crystal coater is used to apply liquid crystal to any of the TFT substrate and the color filter array substrate, which will be referred to as "mother substrate (10)" hereinafter. A panel area is defined on the mother substrate. The liquid crystal coater coats the reference liquid crystal amount in each panel area. 1A, 1B, and 1C are schematic views showing a panel region u defined by a conventional liquid crystal coater dropping liquid crystal droplets on a mother substrate. 4, 201016322 As shown in FIG. 1A, the liquid crystal spreader drops the liquid crystal droplet D from the nozzle N positioned above the predetermined panel area u. As shown in Fig. 1B, the liquid crystal droplets collide with the panel region to change its shape rapidly. As a result, portions of the liquid crystal droplets are forced to break into pieces p. At the same time, air replaces portions of the liquid crystal droplets, thereby trapping inside the remaining liquid crystal droplets. As shown in Figure 1C, the debris P bounces off the panel area and falls elsewhere. The debris P may fall on a rectangular sealant pattern formed around the panel area. In the subsequent attachment procedure, the two mother substrates are not attached to each other well. The debris P may fall outside the rectangular sealant pattern. This causes a shortage of the reference liquid crystal amount of the panel region U. Then, the air A trapped inside the liquid crystal droplets causes the liquid crystal layer interposed between the two mother substrates to generate air bubbles. Since the liquid crystal droplets fall in the panel area with a considerable impact, after the two mother substrates are secreted, the symbol s on the LCD panel. SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to coat the respective panel regions defined on the mother substrate by the same amount of liquid crystal as the reference liquid crystal. SUMMARY OF THE INVENTION The object of the present invention is to dig a plurality of liquid crystals of a reference liquid crystal amount on each of the panel regions defined on the mother substrate. 201016322 Another object of the invention is to avoid trapping air within the liquid crystal droplets. Another object of the present invention is to prevent the droplet marks from being present on the LCD panel after the two mother substrates are attached to each other. According to an aspect of the present invention, a liquid crystal coater comprising: a main frame; a platform provided on the main frame; a coating head unit support frame movably connected to the main frame, the first driving unit, and a moving coating head a unit supporting frame; a second driving unit provided to the coating head unit support frame; and a spraying device | ^ a coating head unit supporting frame movable by the second driving unit.

The linear drive unit 8〇〇 moves the rotary drive unit 70A up and down. ❹ _ _ driving unit _ including moving member 810, first fixing member (four) fixing member 83G, third rotating motor 84g, and ball screw A member f member 810 fixedly coupled to the side of the rotating drive unit And provided through the hole 231 of the rear plate 232 from the upper plate of the rear plate 232 = fixing member (four) is provided on the upper side of the rear plate 232. The second fixing is fixed to the first fixing plate 3= then the third rotating motor 840 provides a slewing-rotating motor as shown in the figure. The liquid crystal is sprayed through the mouth 323, and the pipe is connected to the flow of the spraying unit and the cylinder assembly. 323 = between the outlets, and the single tube t _ is connected to the spray unit 900 and the outlet is connected to the support plate as shown in FIG. Support floor _ 支撑 not support assembly 200. 201016322 Figure 6 is a front view of the spray unit shown in Figure 5. Fig. 7 is a view showing the spray unit spraying liquid crystal on the panel area. As shown in Figs. 6 and 7, the painting unit 9A includes a housing 910, a connecting tube 920, a piezoelectric device 930, a cable 940, a first shock absorber 95, and a second shock absorber 952. The housing 910 includes an inlet 911 and an outlet 912 through which the liquid crystal flows into the housing 910 through the inlet 912 and sprays the liquid crystal through the outlet 912. The connecting port 92 is connected between the inlet 911 and the outlet 912. The piezoelectric device 930 vibrates the connection tube 920. Cable 940 carries current to piezoelectric device 930. The first shock absorber 951 is located between the connecting pipe 920 and the inlet 911. The second shock absorber 952 is located between the connecting tube 920 and the outlet 912. The inlet 911 is connected to the outflow port 323 by means of a pipe 990. The liquid crystal discharged through the outflow port 323 passes through the tube member 990 and the inlet 911 and flows into the connecting tube 920. A piezoelectric device 930 in the form of a donut is inserted into the housing 910 and surrounds the connecting tube 920. Piezoelectric device 930 can be in the form of any vibrating connection tube 92〇. When the electric field is applied, the piezoelectric device 930 generates mechanical stress, thereby vibrating the connection 920. The higher the frequency of the current supplied to the piezoelectric device 930 through the cable 940, the more the connecting tube 920 vibrates. The frequency of the connection tube 92 〇 vibration can be larger than 2 〇 Kt^. The vibration of the connecting tube 920 causes the liquid crystal flowing into the connecting tube 92 to vibrate. For example, 201016322, the crystal L is broken into very small particles C. · · . The result is that the liquid crystal l is sprayed through the outlet 912. The first shock absorber 951 and the second shock absorber 952 prevent the housing 910 from vibrating when the connecting tube 920 vibrates. The first shock absorber 951 and the second shock absorber 952 may not be provided. In this case, the housing 91 〇 also vibrates. The first shock absorber 951 and the first shock absorber 952 may be made of rubber capable of absorbing vibration. The operation of spraying the liquid crystal on the panel area defined on the mother substrate will now be described. As shown in Figures 3 and 4, the rotary drive unit 7 turns the piston 4'' so that the groove 430 of the piston 400 faces the inlet 322 of the cylinder. Once the groove 430 faces the inflow port 322', the rotary drive unit 7 stops rotating the piston 4''. The linear drive unit 800 moves the rotary drive unit 7 up a predetermined distance. This will also move the piston 4〇〇 upwards. The suction space is formed on the bottom side of the piston and the upper side of the cover member 34 in the piston hole 321 . The higher the piston up, the suction air_large, and the lower the pressure in the piston hole 321 becomes. The pressure difference between the inside and the outside of the cylinder causes the liquid crystal in the bottle 520 to flow into the suction space through the first tube 53 and the flow population 322. A living base 400 is moved upward by a predetermined distance, the linear drive unit 8 (10) stops moving the piston upward, and then the rotary drive unit rotates the piston 201016322 400 such that the groove 430 of the piston 400 faces the outflow port 323 of the cylinder 32. Once the groove 430 faces the outflow port 323, the rotary drive unit 7〇〇 stops rotating the piston 400. The linear drive unit 800 moves the rotary drive unit 7 downward for a predetermined distance. This will also move the piston 4 down. The lower the piston 400 moves downward, the smaller the suction space. The downward movement of the piston 4〇〇 forces the liquid crystal in the suction space to be discharged to the outside through the outflow opening 323. As shown in Fig. 7, the liquid crystal discharged through the outflow port 323 flows into the connecting pipe 920 through the pipe member 990 and the inlet 911 of the spraying unit 900. When an electric field is applied, the piezoelectric device 930 generates mechanical stress, thereby vibrating the connecting tube 920 at a frequency of more than 20 kHz. The vibration of the connecting tube 920 causes the liquid crystal 1 flowing into the connecting tube 92 to vibrate. This causes the liquid crystal L to break into very small particles C. As shown in Fig. 7, these very small liquid crystal particles fall through the outlet 912 in the panel region U. Fig. 8 is a view showing four regions in which the liquid crystal sprayed by the spray unit falls on each of the four panel regions defined on the mother substrate. 15 201016322 As shown in Fig. 8, very small liquid crystal particles c are used to diagnose four regions of each panel region of the four panel electrical domains u. - The weight of the liquid crystal particles which are very small is much smaller than the weight of the liquid crystal droplets, so that the non-* small liquid crystal particles do not bounce off from the panel area than the liquid crystal droplets. This ensures that very small liquid crystal particles do not fall elsewhere, such as on the sealant (glue) pattern. Therefore, the need to compensate for the shortage of liquid crystals is eliminated. Furthermore, since the impact of very small liquid crystal particles falling on the panel region is much smaller, the droplets are not marked on the LCD panel after the two mother substrate members are attached to each other. The present invention may be embodied in many forms without departing from the spirit and scope of the invention. It should be understood that the above embodiments are not limited to the details of the description, and should be in the spirit of the appended claims. Under the mouth of the mouth, the broad interpretation of 'therefore all changes and modifications that fall within the spirit of the scope of the patent application and the scope of the definition of the spirit of the invention are intended to be covered. Attached to the scope of the patent application.
