BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum dispensing apparatus for a rotary type display panel cleaning apparatus, and more particularly, to a vacuum dispensing apparatus for a rotary type display panel cleaning apparatus which comprises a panel adsorption unit in which a panel is vacuum- To a vacuum dispensing apparatus for a rotary type display panel cleaning apparatus in which a display panel is sucked and fixed on a rotating turntable.

2. Description of the Related Art [0002] In recent years, a great deal of attention has been focused on the enlargement and upscaling of display devices as a transmission medium of image information in recent years. Accordingly, various flat panel display devices replacing a CRT (Cathode Ray Tube) same. One of these flat panel display devices, liquid crystal display devices, has been greatly developed to the level of CRT or more in terms of image quality, sharpness and color, and becomes a main product dominating the world market.

A general manufacturing process of a general TFT-LCD panel (Thin Film Transistor Liquid Crystal Display Panel) constituting the above-described liquid crystal display device will be described below. First, one pixel (consisting of three sub-pixels of R, G, and B) of a TFT-LCD panel as an outline is fine with a width of about 0.3 mm. Of course, the size of a TFT (Thin Film Transistor) that enters it is smaller. Furthermore, for a resolution of 1600 x 1200, the number of pixels is 192 million, and if we consider each subpixel to be 3 times (R, G, B), we need 576 million TFTs. Therefore, a semiconductor-level process is required for a process in which the precision of the entire process itself must be high.

Meanwhile, the manufacturing process of the TFT-LCD panel as described above is divided into a TFT process, a color filter process, a cell process, and a module process. One panel is made through a cell process, a panel through a cell process is processed through a module process, and a TFT-LCD panel is produced, which is actually used for a monitor or a TV.

First, the TFT (Thin Film Transistor) process is a process of forming a basic electrode, and it is the most fundamental but also the electrode of each cell is formed as a core process. The process sequence includes five steps of forming a gate electrode, forming an insulating film and a semiconductor film, forming a data electrode, forming a protective film, and forming a pixel electrode, but at least one pattern process is required for each step. This pattern process can be called the core of the TFT-LCD panel manufacturing process, and it needs similar pattern process to the CF process as well as the TFT process.

The patterning process as described above is a very precise and complicated process by itself. In order to make one TFT-LCD panel, at least this process is repeated several times. Of course, the schematic process is similar, although not then using the same deposition material and process. This patterning process is performed in the order of deposition, cleaning, photolithography (PR) coating, exposure, development, etching, PR stripping, Is required.

On the other hand, TFT-LCD controls the brightness of light by adjusting the arrangement of liquid crystal in each cell such as PDP or OLED (Organic EL) so that each cell does not emit itself but a certain light emitted from the backlight. Since the backlight itself is a white light, the amount of light is controlled by varying the arrangement of the liquid crystal, but a color filter (CF) plays an important role to make R, G, B to realize color. Such a CF is located on the top surface of a TFT-LCD panel and is manufactured through a separate process from the TFT process. The CF process also requires the pattern process described above.

The above-mentioned CF (Color Filter) process requires a patterning process in the BM (Black Matrix) process (deposition, cleaning, PR coating, exposure, development, etching, It is a slightly different process from that of the sputtering process. It is necessary to apply a photosensitive material having color to it without using a deposition and cleaning process, and it can be exposed and developed.) And ITO process (Indium Tin Oxide: Good in transparency and conductivity, Excellent transparent electrode material). In addition, some additional processes may be added depending on the type of panel (VA, IPS, TN, etc.).

In addition, the cell process is a process of cutting and combining two glasses made by the CF process and the TFT process into one, and is used for CF and TFT cleaning, polyamide printing, rubbing process, (The TFT substrate and the CF substrate are precisely adhered to each other), and cut (separated into individual panels by cutting the bonded substrates), liquid crystal injection, and final inspection.

During the manufacturing process of the TFT-LCD panel as described above, the module process is the final step for manufacturing the finished product panel, and is the final step of attaching the polarizer, the PCB, and the backlight unit to the panel made by the cell process. This module process consists of cleaning, polarizer attachment, TAB attachment, autoclave, PCB attachment, BLU (Back Light Unit) assembly and inspection.

Meanwhile, in the process of manufacturing the TFT-LCD panel through the TFT process, the CF (color filter) process, the cell process and the module process as described above, a process of removing foreign substances and particles on the glass or panel And the glass or panel is cleaned while passing through each process, thereby preventing defects such as defective pixels of the TFT-LCD panel.

As a conventional display panel cleaning apparatus for removing foreign matter and particles on the panel (or glass) of each process in the process of manufacturing the TFT-LCD panel as described above, there are a hot water shower unit, a cleaning apparatus using a cotton cloth, And a cleaning device using a polishing belt are provided.
