The present invention relates to a packaging device for a flat panel display module, and more particularly, to a packaging device that can be safely transported at high density without risk of damage.

A flat panel display such as a plasma display has a spotlight that can replace a cathode ray tube (CRT) display because it can display a large screen but has a small thickness and a small volume. In particular, the plasma display device has advantages in various display characteristics such as display capacitance, brightness, contrast, viewing angle, and the like.

In order to form a plasma display device, a plasma display panel (hereinafter referred to as a PDP) having an auxiliary structure such as an electrode, a partition, and a phosphor layer is first formed on two substrates by using processes such as printing and photolithography. Frames, circuits, and the like are installed in these panels to form a plasma display module. In this process, the panel or module is packaged and transported into a packaging material, which is subsequently processed by a set maker to form a plasma display device set.

Prior to protection by an external case or the like, the plasma display panel (PDP) has a plurality of structures having two relatively large and relatively thin glass substrates inside thereof, and the surroundings are enclosed by the frit glass in a low pressure resistance state. In this state, since a large portion of the substrate which is easily damaged by external impact is exposed, great care must be taken in the packaging and storage of the plasma display panel or the plasma display module during the transfer to the subsequent set production process for forming a product. In addition, in order to prevent contamination of circuits and the like from the outside, reliable packaging of the module should be made.

Plasma display panels usually have a large area of 40 inches or more and thus occupy a large volume, and therefore, packaging the panels or modules in a safe and high density is very important for improving transportation efficiency and preventing damage during transportation.

1 is an exploded perspective view showing an example of a conventional packaging method or a packaging device configuration, Figure 2 is a side cross-sectional view showing a conventional packaging method using a back cover different from FIG.

Referring to FIGS. 1 and 2, a conventional packaging method and apparatus configuration will be described. First, the modules 11 and 21 are combined with support members 12 and 22 made of a wide plate or cardboard covering the module. (10) Form a state. 1 shows a case where a wide plate or paperboard is simply used as the support member. In Fig. 2, the module is coupled to a wide container-type back cover which is open on one side and covers the side and the rear to form a packing unit.

The lower end of the packing unit is inserted into the grooved styrofoam cases 14b and 24b or cardboard cases side by side, and is installed in the lower box 16b together with the case. The upper end of the packing unit 10 is similarly fitted into the grooved cases 14a and 24a and covered with the upper box 16a covering the lower box.

Referring to FIG. 1, the module packing will be described further. The PDP module packing unit 10 installed in the case 13 is stored in boxes 16a and 16b. The boxes 16a and 16b serve to prevent foreign matter from entering the outside or to protect the PDP module 11. The boxes 16a and 16b are divided into two parts, the upper box 16a and the lower box 16b to facilitate packaging.

The lower surface of the upper box 16a is open, and the height of the lower box 16a is preferably higher than the height of the PDP module packing unit 10 in consideration of the thickness of the groove portion of the case. When the lower case 14b is installed in the lower box 16b and the PDP module packing unit 10 is housed in the groove 14c of the lower case, the upper case 14a is covered and the upper box 16a is covered from above. Will be packed. Reinforcing members 15 are installed on the upper and lower cases 14a and 14b to contact the lower surface of the upper box 16a and the upper surface of the lower box 16b, respectively.

By the way, the upper and lower end of the packing unit is fixed to the styrofoam case or cardboard case is good cushioning, but the rigidity is insufficient to easily break when an external force is applied through the packing unit. For example, the distance between the grooves of the case is reduced according to the tendency of high density loading, and the partition wall thickness between the grooves into which the adjacent packing units are fitted becomes thin, and the direct contact between the loaded module and the support member, the collision, The problem of breakdown is increasing.

In addition, even when the packing unit is incorrectly placed in the groove of the case, the packing unit may be inclined, and the case of the front packing unit and the panel of the rear packing unit exposed to the front may be in contact with each other and the panel of the rear packing unit may be damaged.

The present invention is to alleviate the problems of the packaging device for the transfer of the conventional flat panel display module described above, even when the flat panel display module is densely loaded flat plate to ensure a safe distance between them against external impact An object of the present invention is to provide a packaging device for a display module.

In another aspect, the present invention provides a packaging device for a flat panel display module having a safe structure such that even when the module is densely loaded, a support and packaging member such as a case of an adjacent packing unit does not directly contact the vulnerable panel portion of the rear flat panel display module. It aims to provide.

It is another object of the present invention to provide a packaging device for a flat panel display module having a configuration capable of reducing material costs as compared with the prior art.

It is an object of the present invention to provide a packaging device for a flat panel display module that can be densely loaded with a flat panel display module without the risk of breakage during packaging, thereby increasing transport efficiency and packaging efficiency.

The packaging device for a flat panel display module of the present invention for achieving these objects is covered with a support member which forms a packing unit in combination with the module so as to surround the width of the rear and top and bottom of the module, the support member is at least a module It is characterized by comprising a front cover to cover a portion of the front upper and lower ends.

In this configuration, it is preferable that the supporting member is formed in a predetermined width in a band shape, and may be formed as one, but may be formed into two or three pieces according to the size of the flat panel display module to be combined into one module. desirable. In addition, each divided support member may be made to be coupled to the wall-mounted boss formed in the chassis base of the module.

The support member of the present invention is generally perpendicular to each other by a portion bent at approximately 90 degrees to cover the back, top, and bottom of the module, and thus basically have a c-shaped portion. In addition, in some cases, it may be formed so as to cover the front, rear, and top and bottom of the module in a U-shaped. In addition, the support member may be preferable in that it is rigid and is made to remain spaced apart from the module except for a part of the coupling part such as a boss, in that it does not directly transmit an external shock to the module.

Except in the case where the support member is formed in the shape of ㅁ, the front end portion of the portion covering the upper and lower portions of the support member is bent toward the module to cover the upper and lower ends of the module, or the flange portion is formed at the front end. You can do that. Alternatively, a separate module front cover part may be formed to be coupled to another part covering the upper and lower parts and the rear of the module by using a separate fastening member, or may be coupled by a frictional force by fitting. In this case, when the separate cover part has a basically one-shaped structure to continuously cover the upper and lower ends of the front, it will be combined with the remaining part having a basically c-shape to form a K-shaped support member as a result.

On the other hand, the packaging apparatus of the present invention may further have a case and a box in which the case is built so as to load a plurality of packing units together with a support member which is directly coupled to the display module to form a packing unit.

In the present invention, the case may be a structure having a groove formed so that the individual packing unit is stacked, and a partition for separating these grooves as in the prior art, but the groove of the packing unit is continuously stacked in front and rear without forming a groove for the individual packing unit It may have a rail-shaped groove suitable for loading the support member.

In addition, in the present invention, the case is provided with an upper case and a lower case one by one to cover the packing unit in the upper and lower sides, the upper and lower cases may each be composed of one member, at least one of the upper and lower cases are two parts It may be divided into. In this case, the material cost and weight of the case can be reduced.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. However, in relation to the description direction, the screen of the module is viewed forward and the frame portion is viewed rearward, and when viewed from the front, the top, bottom, left and right sides will be considered as top, bottom, left and right in the description.

Figure 3 is an embodiment of the present invention, the band-shaped support member 30 has a substantially U-shape, the front end of the portion covering the module from the upper side of the bent portion 33, the downward cover the module from below At the front end of the portion, the bent portion 33 is formed upward. The size of the bent portion 33 is preferably formed to a sufficient length so that the front band-shaped support member 30 does not touch the panel of the lower packing unit, even if the packing unit loaded in the packaging case in front and rear has some flow space. Do. In this case, however, when the module is loaded on the band-shaped support member 30, there is a disadvantage in that it is difficult to load the module in the front direction partially open from the support member. In this case, in the step of forming the packing unit by coupling the module and the band-shaped support member 30, the support member may be coupled to the left and right sides of the module.

4 is a configuration example for overcoming the difficulty in FIG. 1 according to another embodiment of the present invention. In Fig. 4, the band-shaped support member 40 of the packing unit has a closed curve when viewed from the side in a U-shape as a whole. In order to achieve this shape, the U-shaped support member portion 42 is first approached from the rear of the module to be coupled to the module, and the U-shaped support member portion 43 is approached from the front to the upper and lower ends of the U-shaped support member 42. To be combined with the top and bottom of the

As an example of the joining method, a flange portion 431 is bent backwards at the upper and lower ends of the one-shaped support member portion 43 to join the c-shaped portion with the one-shaped portion, and the flange portion 431 and the c-shaped support member portion are made. In (42), it can overlap with the part which covers the upper and lower parts of a module slightly. And, although not shown, to form a hole in the overlapping portion to be fastened by a screw means, or to form a groove and a projection in the corresponding portion to be combined with the groove and the projection by fitting, or simply by frictional coupling to be coupled by friction. Can be.

3 and 4 may be formed by bending a metal plate having a predetermined width by a press or the like. In order to increase the accuracy of the press working, the bent portion of the metal plate may be formed in advance by thin rolling.

The band-shaped support members 30 and 40 preferably form holes 31 and 41 to be coupled to the wall-mounted boss formed in the chassis base of the module. If the wall mounting boss of the module and the holes 31 and 41 of the support member are aligned in the forming of the packing unit, a method of fastening with a screw or bolt may be used. At this time, most of the support member is spaced apart from the module to protect the shock from the outside, and even when the external object touches the support member, the support member can be buffered, protected without transmitting the impact to the module.

On the other hand, the band-shaped support members 30 and 40 should have a certain mechanical strength in order to buffer, protect the module. Therefore, it is preferable to be formed more than a predetermined thickness so as to maintain the shape during use, and even if the thickness is small, it is conceivable to have ribs erected in the form of flanges on both sides of the band-shaped support member. When placing the ribs on the plate first, the ribs of the bent portion can be slightly reduced in width so that the ribs are not pushed outward or inward to form sharp or widened portions during bending. As a result, the rib of the reduced width forms the groove 45.

5 and 6 are side cross-sectional views schematically showing a state in which a packing unit in which a supporting member and a module are coupled to a packing case is loaded.

Conventionally, a groove is made in a case formed of a straw foam or the like so that there is no contact between the packing modules, a packing module is loaded at a groove position, and a partition wall of a material forming a case is formed between the groove and the groove, that is, between the packing module and the packing module. This exists.

In contrast, as shown in the present invention, a partition wall may not exist between the packing modules stacked in the front-rear direction between the upper case 54a and the lower case 54b. That is, the band-shaped support members 30, 42, and 43 of the packing modules stacked adjacent to each other in the front-rear direction may directly contact each other. Accordingly, the space between the front and rear packing modules can be reduced as compared with the case of the partition wall, and the number of modules that can be loaded in the packing boxes of the same size also increases.

However, since the front end of the supporting member must be positioned in front of the front panel of the module 21 to protect the panel surface of the module 21, the chassis base and panel thickness and wall thickness for forming the front and rear thickness of the module 21 are used. The length of the portion formed in the front-rear direction of the support member, for example, the portion covering the vertical direction of the module 21, should be longer than the size of the boss 211.

5 and 6, the c-shaped support member 42 in front of the c-shaped support member 42 is covered with the one-shaped support member 43, rather than the example of FIG. It can be considered that the example of Fig. 6 that the band-shaped support member represents is safer.

7 and 8 are a perspective view showing an embodiment of a styrofoam case in which the packing unit is loaded in the packaging apparatus of the present invention and an example in which the packing unit is loaded in the case.

When packaging is made so that the supporting members 30, 42, and 43 of the packing unit directly touch as shown in FIGS. 5 and 6, the packing density is increased, thereby reducing the transportation cost, but may be vulnerable to external impact. It is preferable to use a shock absorbing material that can better cushion the external shock, it may be made of a material such as strofoam as in the prior art. When shock absorption is a problem, the case is made of a groove as in the prior art, it is also possible that the module 21 to which the band-shaped support member 40 of the present invention is coupled is loaded in the groove of the case as in the prior art.

However, when having a packing module loading form as shown in Figs. 5 and 6, which can increase the loading efficiency, the cases 64a and 64b are suitable for loading the packing unit to which the supporting member 40 of the packaging device of the present invention is coupled. It is preferable to take the form as shown in Figs.

According to Fig. 7, the cases 64a and 64b are largely divided into an upper case 64a which covers the packing unit from the upper side and a lower case 64b which protects from the lower side, and the lower case is composed of two parts again. That is, the lower case has an empty middle portion, is separated on both sides, and has a rail-shaped groove 65b corresponding to the width of the support member 40 in the packing unit. The formation direction of the rail-shaped groove 65b becomes front and rear, which is a direction in which the plurality of packing units are arranged to be stacked, and this usually coincides with the loading direction of the packing unit. Accordingly, when the packing unit is stacked, both parts of the lower case 64b may be aligned, and the packing unit may be sequentially loaded from the rear by pushing the packing unit high in front and pushing the packing unit along the rail groove 65b. The rail-shaped groove 65b may be combined with the lower part of the lower module 21 of the support member 40 to fix the packing unit so that the packing unit does not move in the left and right directions during transportation.

On the other hand, the upper case 64a is divided into front and rear portions, and the middle portion is empty. This arrangement has the effect of reducing the case material, it is possible to increase the packaging efficiency compared to the material cost because the packing unit is wrapped so that the separate upper and lower cases can cope with any direction of the shock as a whole.

According to the embodiment, the upper and lower cases are all made of one, and the middle part is not emptied, and the rail-shaped groove may be formed in the front-rear direction in which the packing unit is loaded similarly to the case of FIGS. 7 and 8.

On the other hand, both ends of the rail-shaped groove (65b) of the lower case (64b) may be formed with a projection (67b) that serves to prevent the packing unit from falling off from the case, the projection (67b) is a rail-shaped groove (65b) It may be formed over the entire side forming both front and rear ends of the lower case 64b. This protrusion 67a may be applied to the upper case 64a in the same manner. The form in which the protrusions are formed can be seen in FIG. 7 or in FIG. 9, which is a cross-sectional view of the rail groove of FIG. 8 vertically cut in the direction of the rail groove.

The protrusions 77a and 77b may be formed not only on the sides forming the front and rear ends of the upper and lower cases 74a and 74b but also on the side portions forming the left and right ends, but as illustrated, the protrusions on the left and right ends are not formed. Referring to FIG. 1, the lower case 74b is eventually installed in the lower box 16b, but since there is no separate left and right protrusions, the side wall of the box serves to fix the packing unit. However, the upper and lower cases 74a and 74b and the protruding portions 77a and 77b formed in the periphery thereof can act as a shock absorbing material applied to the outside at the same time as the finishing wall, so it is preferable to be installed within a very thick range.

In the packaging device for a flat panel display module according to the present invention, since all the supporting members of the packing unit cover the module at the same position, the supporting members may be in contact with each other, but the supporting members and the panel of the module may not be directly in contact with each other. Therefore, it is possible to prevent the module from being damaged due to an external impact in the packaging device or the support member of the packing unit and the modules of the neighboring packing unit coming into contact with each other during the packaging process.

In addition, since the packing unit can be stacked in such a way that the supporting members touch each other, there are no grooves into which the packing units are inserted and no partition wall between the grooves, thereby reducing the empty space in the packing box. As a result, the flat panel display module can be loaded at a high density during packaging, thereby increasing the efficiency of module packaging and conveying operations.
