A cleaning process for removing impurities on the surface is further included in such a process. After the cleaning process, a drying process is required to dry and remove the cleaning liquid.

Patent literatures 1 to 3 are techniques related to such a panel drying apparatus.

[0004] Patent Document 1 discloses a drying apparatus for drying at least one far-infrared ray, comprising: at least one far-infrared ray using drying unit for heating by an electric heating body to convert heat energy into far infrared rays, And a guide for guiding radiated far infrared rays to the object to be dried. Patent Document 2 discloses a far infrared ray radiation drying apparatus comprising a loading device for loading a plurality of wafers onto a cassette, a plurality of cassettes A drying oven for drying the wafers while sequentially transferring the cassettes, a carry-out device for taking out the wafers from the cassette discharged from the dry oven, and a transfer device connected to the loading device and the take-out device,And a conveying device for conveying the empty cassette to the loading device.

This conventional drying apparatus simply removes moisture or particles by blowing compressed air on the surface of the LCD panel. Even if it is installed in multiple stages, it is possible to remove water droplets formed on the surface of the LCD panel, It is impossible to completely remove moisture deposited on the substrate.

Patent Document 3 has been developed to overcome such disadvantages. In this drying apparatus, an air knife is provided in a drying chamber provided on a conveyance path for conveying an LCD panel. In the drying apparatus, an air which is installed at a predetermined interval above / below an LCD panel A primary drying chamber having a strong wind drying portion including a dehumidifying portion for removing moisture contained in air connected to the knife; A dehumidifying part 2 for removing moisture contained in the air that is separately provided through the partition wall at the next stage of the primary drying room and an air blower installed at the upper part of the drying room for spraying dehumidified air on the entire surface of the LCD panel while being connected to the dehumidifying part 2 A secondary drying chamber having a dehumidifying and drying section including a fan; A third drying chamber having a heating / drying section including a near-infrared lamp which generates strong heat, which is installed at a predetermined interval on an upper / lower portion of an LCD panel, which is conveyed through a conveying means, .

The conventional drying apparatus configured in this manner has a drawback that the structure is complicated because it includes a multi-stage drying chamber. A drying apparatus having upper and lower chambers configured as shown in Fig. 8 is developed.

That is, as shown in FIG. 9, an upper chamber 100 provided with a lower heater provided with a transfer roller therein, and an upper chamber 200 provided at an upper portion of a lower chamber provided with a lower heater, A control box 300 is provided below the lower chamber.

As shown in the drawings, the conventional panel drying apparatus has a structure in which one end of the upper chamber is coupled to a hinge 400 at one end of the lower chamber, and the upper chamber is opened and closed by rotating.

When the upper chamber is frequently opened and closed in the hinged state, the hinge 400 is easily aged and the upper chamber can not be opened and closed smoothly, and the number of work processes is increased and the installation space is increased.

Even if the upper cable (not shown) is lifted and lowered by the lifting means 30 interlocked by the lifting means 30 and raised and lowered vertically, So that it can be electrically connected to the upper heater.

At this time, due to the repetitive movement of the moving side, much dust is generated due to the abrasion phenomena due to mutual friction between the cable bare connection portion 42 and the metal cable bare bracket 41. However, during the actual glass drying process, It is possible to prevent the dust from penetrating into the glass at the source.

Since the structure of the cable bear 40 is a well-known technology, a further detailed description will be omitted.

4 is a perspective view showing an installation structure of an air curtain of a glass drying apparatus for a display device according to an embodiment of the present invention.

As shown in FIG. 4, when external air flows into the internal space sealed by the upper chamber 20 and the lower chamber 10, not only the thermal efficiency is lowered but also external moisture may be introduced into the interior, 11, the air curtain 13 is integrally formed to block the outside air.

Thus, the air curtain 13 is installed integrally with the lower chamber on the side of the inlet 11, thereby reducing the number of work processes and reducing the production cost.

Here, in the illustrated example, the air curtain 13 is provided on the inlet 11 side, but it is needless to say that the air curtain is also provided on the outlet 12 side.

5 is a perspective view showing a structure of driving means of a conveying roller of a glass drying apparatus for a display device according to an embodiment of the present invention.
