In order to allow the above-described partial conveyor belt 700 to move up and down on the platform 200 and the production line conveyor belt 600, grooves or grooves G are formed in the platform 200 and the chassis 100. The grooves G described above each have a shape corresponding to the shape of the partial conveyor belt to allow the partial conveyor belt 700 described above to overlap the platform 200 and the chassis 100. When the partial transfer belt 700 is raised above, the roller 740 of the partial conveyor belt 12 1321114 700 is located on the upper surface of the platform 200. Conversely, when the partial conveyor belt 700 described above is lowered, the roller 740 of the partial conveyor belt 700 described above is located in the groove G in the platform 200.

The partial conveyor belt 700 overlying the production conveyor belt 600 is positioned above the roller shaft 610 of the production conveyor belt 600. Referring to Fig. 5, when the partial conveyor belt 700 described above is lowered, the upper surface of each of the rollers 740 of the partial conveyor belt 700 is lower than the upper surface of each of the rollers 620 of the production line conveyor belt 600. Conversely, when the partial conveyor belt 700 described above is raised, as shown in Fig. 6, the upper surface of each of the rollers 74 of the partial conveyor belt 700 is higher than the upper roller 620 of the production line conveyor belt 600. surface. The radius of the roller 620 of the above-described production line conveyor belt 600 is greater than the diameter of the roller 740 of the partial conveyor belt 700. The operation of the liquid dispensing system in accordance with the present invention will be explained in accordance with a process in which the liquid crystal is dispensed onto a substrate (glass). First, the roller shaft drive unit 操作 of the production line conveyor belt 600, and a rotational force of the above-described roller shaft drive unit 传送 are transmitted to the above-described roller shaft 610 to rotate the above-described roller shaft 610. With the above roller shaft 610 13 1321114

Rotating, the rotating surface is coupled to the roller 620 of the roller shaft 610 described above. The substrate on the roller 620 is transferred to the local conveyor belt 700. The roller shaft drive unit of the wire conveyor belt 600 stops operating. As shown, at this point, the partial conveyor belt 700 is in a lowered state.

The substrate on the roller 740 of the partial conveyor belt 700 as described above is raised by the elevation drive unit 800 as the substrate is positioned above the partial conveyor belt 700. The substrate on the roller 740 of the partial conveyor belt 700 rises upward. Next, if the partial conveyor belt 700 driving unit M1 is operated, one of the roller shaft drive units M1 is fed to the above-described roller shaft 730 to rotate the roller shaft 730. Once the shaft 730, the roller 740 coupled to the roller shaft 730 rotates and passes from the substrate on the roller 740 described above to cover the platform and then stops the roller shaft drive unit M1 U of the partial conveyor belt 700. Then, the above-mentioned lifting drive is operated. Unit 800 is to lower the belt 700. When the partial conveyor belt 700 is lowered, the substrate on the partial delivery roller 740 is moved onto the platform 200. In a state where the substrate is located on the platform 200, the dripper tube and the dripper unit 500 on the dripper support member 400 are operated, thereby dispensing the liquid crystal in the form of dropping the dripper of the dripper according to a preset pattern. In this example, the platform 200 may not be operated, but instead the drip head and dripper unit 500 may be operated to determine the dripper header of the dripper unit 500. When the liquid crystal dispensing is completed and dropped onto the substrate, the above operation is performed and is located, in the state of Fig. 7, when 700, the roller shaft of the roller is rotated to rotate the roller and the transfer position 200 is operated. Partial conveyor belt 700 struts 4 0 0 unit 500 board. At the position of the struts 4 0 0 J (the lifting unit 14 1321114 8 00 to raise the partial conveyor belt 700. When the partial conveyor belt 700 is raised by the lifting unit 800, the roller 740 of the partial conveyor belt 700 where the substrate is located is After raising the partial conveyor belt 700 described above, the roller shaft drive unit M1 of the partial conveyor belt 700 is operated to rotate the roller shaft 730 and thereby rotate the roller 740. Once the roller 740 is rotated, it is conveyed by the partial conveyor belt 700. The substrate is overlaid on the production line conveyor belt 600. Next, the operation of the roller shaft drive unit M1 of the partial conveyor belt 700 is stopped.

The partial conveyor belt 700 is then lowered by the lift drive unit 800 and the substrate on the rollers 740 of the partial conveyor belt 700 described above is moved onto the rollers 620 of the production line conveyor belt 600. Once the above-described production line conveyor belt 600 is in operation, the substrate on the roller 620 of the production line conveyor belt 600 is transferred to the next stage by the above-described production line conveyor belt 600 for the next step.

According to the present invention, the substrate is transported by the above-described production line conveyor belt 600, and the transported substrate is loaded on the platform 200 by the operation of the partial conveyor belt 700 and the lift drive unit 800. Therefore, if the substrate constituting a mother glass is increased in size as the mother glass becomes larger, the substrate can be stably transported. Once the above substrate becomes too large, the large substrate can be stably transferred by increasing the width of the line conveyor belt 600 and the partial conveyor belt 700. Moreover, according to the present invention, the liquid can be reached by operating only the dripper support 400 and the dripper unit 500 without operating the platform 200 15 1321114

distribution. Therefore, even if the platform 200 becomes larger as the substrate becomes larger, the overall size of the substrate can be reduced, and the required equipment space can be minimized to easily move the system. In addition, since there is no need to operate to the platform 200, the size of the platform is increased and thus the weight is increased and the system can be stably driven. As described above, according to the present invention, even if the above substrate size piece is easily adjusted by the system to conform to the increased size, the above substrate is still transported. Therefore, the utility and reliability of the system are increased. Furthermore, since the above-described dispensing system is driven only by operating the dripper support and the dripper unit without operating to the platform, even if the above-mentioned table becomes larger as the size of the substrate increases, the system can be stably transmitted. The reliability of the system is increased because the process for dispensing a liquid such as liquid crystal, a sealing material or silver onto the substrate can be stably performed.
