FIG. 4 illustrates a state before packing the plasma display assembly 300 according to an embodiment of the present invention, and FIG. 5 illustrates a state after packing the plasma display assembly 300 of FIG. 4. It is.

4 and 5, the apparatus for packaging the plasma display assembly 300 is provided with a plurality of holders 40 and an envelope 400.

Upper and lower portions of the plasma display assembly 300 are provided with a fixing stand 40 to be detachable. The fixing stand 40 includes a plurality of upper fixing stands 41 and lower fixing stands 42 so as to fix them at the upper and lower portions of the plasma display assembly 300, and the upper and lower fixing stands 41. 42 is located only in the opposite direction and has substantially the same shape.

The fixing table 40 is a block 43 of a rectangular hollow. The block 43 has a space portion having a constant width and depth in the longitudinal direction. Accordingly, the mount 40 is provided with a mounting surface 44 to directly support and support the upper and lower outer surfaces 301 of the plasma display assembly 300. The mounting surface 44 is sized to accommodate the upper and lower portions of the plasma display assembly 300 in the width direction.

At least one fixture 40 may be installed on at least one surface of the upper and lower surfaces of the plasma display assembly 300, or at least one surface of the left and right surfaces may be installed according to a packaging method. In addition, the plasma display assembly 300 may be installed at the upper and lower sides, or at the left and right sides.

An envelope 400 is installed in the plasma display assembly 300 fixed by the holder 40 to protect it from external impact.

The envelope 400 is joined to the edge portion by a separate sealing means after the plasma display assembly 300 is installed to completely seal the plasma display assembly 300 from the outside.

The envelope 40 is preferably one selected from thermoplastic resins having excellent plasticity and good moldability, such as low density polyethylene, high density polyethylene, polypropylene, soft polyvinyl chloride resin, and ethylene resin.

Filling means, for example, a gas such as nitrogen, is injected into the inner space in which the plasma display assembly 300 sealed by the envelope 40 is installed to play a buffer role in order to prevent damage thereof from external shock. .

The packaging process of the plasma display assembly 300 using the packaging apparatus having the above structure will be described in detail as follows.

First, an envelope 400 made of a thermoplastic resin is prepared. The envelope 400 has a width and a length that can completely wrap the plasma display assembly 300. The envelope 400 is provided with a plurality of fixing base 40 by the adhesive adhesive tape 61. The holder 400 is installed at a position corresponding to the upper and lower surfaces of the plasma display assembly 300, and is fixed to the envelope 400 by an adhesive tape 61. . On the other hand, it is preferable to form the adhesive tape 62 in the corner region of the envelope 400 to minimize the change of the position when the envelope 400 is sealed by the sealing means later (Fig. 6).

After the envelope 400 having the fixing table 40 is provided, the plasma display assembly 300 is seated on the envelope 400. In this case, at least one upper fixing stand 41 is installed at an upper portion of the plasma display assembly 300, and a plurality of lower fixing stands 42 is mounted at a lower portion thereof.

It is mounted in the width direction. Accordingly, the fixing of the holder 40 to the plasma display assembly 300 is completed.

After the holder 40 fixes the plasma display assembly 300, the envelope 400 is folded to package the plasma display assembly 300. At this time, the envelope 400 is formed with an adhesive tape 62 in the corner area, thereby maintaining the shape of the envelope 400 without deformation (FIG. 7).

When the packaging of the envelope 400 is completed, the folded portion of the envelope 400 is sealed by applying a predetermined heat using a heating bonding device 80 as a sealing means. The heating bonding device 80 is a device that is heated to a set temperature when the power is supplied as is known, by applying heat and pressure to the surface of the envelope 400 to seal by heat fusion. When the envelope 400 is sealed by the heating bonding device 80, one portion of the envelope 400 is left, and the edge of the envelope 400 is completely sealed. (Fig. 8)

Next, the gas injection means is connected to the gas filling hole of the envelope 400 which is not sealed when the heating bonding device 80 is sealed. The gas injection means includes a storage tank 91 storing a filling gas such as nitrogen, an injection pipe 92 connected to the storage tank 91 to provide a passage for supplying a filling gas, and the injection And a valve 93 installed in the injection passage of the pipe 92 to control the injection amount of the gas for filling, and a nozzle 94 installed at the end of the injection pipe 92 to inject the gas for filling.

When the filling gas is injected into the interior space of the envelope 400 in which the plasma display assembly 300 is built by using the gas injection means, the envelope 400 is connected to the plasma display assembly 300. By the fixing base 40 for fixing the to achieve a certain appearance. Subsequently, the gas injection means is released, and the gas filling hole part is sealed using the heat bonding device 80. Accordingly, the envelope 400 is completely sealed from the outside (FIG. 9).

As described above, the plasma display assembly 300 is fixed up and down or left and right by the plurality of stators 40 and then sealed using the envelope 400 to inject filling gas into the sealed interior space. The packaging is completed.

As described above, the packaging apparatus of the plasma display assembly and the packaging method using the same of the present invention can obtain the following effects.

First, as the plasma display assembly is maintained with a plurality of fixings having a simple structure, manufacturing cost is reduced.

Second, by enveloping the outside of the plasma display assembly fixed by the stator, the influence can be excluded by an external environment such as heavy snow or rain.

Third, as the filling gas is injected into the envelope, the plasma display assembly acts as a buffer even if the plasma display assembly is shocked by an external force or a user's carelessness, thereby preventing the risk of damage.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
