Description

Packaging box for display glass substrate

The present invention relates to a packing box for a glass substrate; and, more particularly, to a package for a display glass substrate that can be packaged in a package for transporting a display glass substrate At the time, it is made of a slot plate made of a polyethylene terephthalate (PET) resin nonexpanded materials and separated for disassembly. The best use of the advantages of expanded resins minimizes the occurrence of surface scratches and substrate pollution.

Generally, glass substrates for displays, such as liquid crystal displays (LCDs), plasma display panels (PDPs), and organic electroluminescence (EL) panels, are stored in a box. The transport and storage, and in particular, the plurality of glass substrates stored in the cartridge are supported in a vertically erected state, whereby they do not come into contact with each other.

A package for a display glass substrate is manufactured by injecting a molded case using a non-foamed resin such as polyvinyl chloride (PVC) and acrylonitrile-butadiene-styrene (Arylonitrile). -Butadiene-Styrene, ABS) resin, but the package made of these materials is relatively heavy and lacks the ability to absorb impact, thereby causing the problem of damaging the glass substrate when the glass substrate is retracted.

Moreover, in some cases, a separate buffering material such as corrugated cardboard is provided in the cartridge to protect the glass substrate from external shock or vibration during transport, However, this cushioning material cannot be reused, resulting in an increase in distribution costs.

In order to overcome the above problems, a method of manufacturing and using a packaging box by replacing a non-foamed resin with a polyethylene and polypropylene series foaming resin is widely used.

1 is a perspective view for explaining an existing package for a glass substrate manufactured by using a foamed resin. Referring to Fig. 1, the cartridge is made of a foamed plastic body configured in a top-opened rectangular parallelepiped shape (1) and a foaming cover for covering the open top of the cartridge body (1). It consists of a plastic cover (not shown). On each inner wall surface of a pair of mutually opposing walls of the cartridge body, projections (3) and substrate insertion grooves (5) are along a height extending therefrom at a specific interval The directions are alternately formed.

Therefore, the plurality of substrate slots (5) are formed by the plurality of protrusions (3) protruding on the inner wall surface of the cartridge body, and the glass substrate stored in the cartridge body (1) is inserted. The pair of mutually opposing substrate slots (5) are then pressed by the projections (3) such that the glass substrate is stored in the cartridge body and maintained in a fixed state.

In the case where the entire package for the glass substrate is manufactured and used only with the foamed resin, the cartridge can be easily transported because it is not the above-mentioned non-fat The box made of plastic is much lighter. In particular, an excellent cushioning function can be achieved to absorb external impact or vibration generated when the package is transported, thereby preventing damage to the glass substrate as much as possible.

However, the package made of this foamed plastic has the following disadvantages when the cartridge will store a display glass substrate requiring good surface quality instead of storing a general flat glass.

That is to say, the box made of foamed plastic can be easily charged compared to the box made of non-foamed plastic, so that the particles contaminated on the substrate slot and the projection can be easily transferred to the glass substrate. And causing substrate contamination such as generation of stains caused by organic materials. In addition, when the glass substrate is inserted into the substrate slot, fine scratches are generated on the glass substrate due to the high friction between the glass substrate and the foamed resin projecting portion and the stress applied to the glass substrate. Therefore, it deteriorates the surface roughness of the glass substrate.

Similar to the above, when the entire package for a display glass substrate is configured with a foamed resin, the cartridge can be easily transported, but it can cause deterioration of surface contamination and surface roughness. Therefore, the throughput is deteriorated due to the deviation of the threshold voltage value of the substrate during the process, which may result in a defective product.

In addition, it is more difficult to clean the substrate slot and the protruding portion protruding from the package made of the above foamed plastic. Therefore, when the cartridge is used again, the organic material and other particles cannot be completely eliminated, which may also cause an increase in substrate contamination.

In order to solve the above problems, it is therefore an object of the present invention to provide a use. a package for a display glass substrate that prevents deterioration of surface roughness caused by fine scratches and surface contamination caused by transfer of organic materials and other fine particles, which is a disadvantage of a case made of foamed plastic, and In addition, the cleaning process for reusing the cartridge can be simply and perfectly performed by separately and easily separating only the factors of fixing the glass substrate and the cartridge main body, which obtains a glass substrate for the glass substrate. The advantages of the box.

A package for a display glass substrate according to the present invention includes: a case main body composed of a wall and a base plate such that the top portion is open and a glass substrate storage space is formed inside; and a pair of groove plates for passing therethrough A plurality of fixing projections support the two edges of the glass substrate stored in the cartridge body to fix the glass substrate, the fixing protrusions being protruded to extend in a height direction on one side And wherein the protruding end is along the height direction of the wall at the edge of the inner surface of the wall of one side of the cartridge body and the edge of the inner surface of the wall of the other side opposite the wall of the one side Individually protruding, and wherein the protruding end is configured to be detachably disposed by a wall connecting the one side wall and the other side wall to form a recess groove, and the groove plate is Made of plate-shaped members separated from the cartridge body, and the two height-direction edges of the plate-shaped member are along the detachable manner when combined with the cartridge body The groove rises and falls, The cartridge body includes a stop projection that protrudes to form a tower wheel on an upper section of at least one pair of mutually opposing walls; the slot plate is on an opposite side of the side on which the fixed projection is provided The upper section is provided with a "sickle-shaped" section stop portion, wherein the fixed projection is positioned such that the "sickle-shaped" stop Partially latched onto the stop projection to be detachably combined with the cartridge body; and the cartridge body is foamably formed of a foamed resin material, and the slot plate is selected It is formed from at least one of PET, amorphous PET (A-PET), and PET-G resin.

According to the package for a display glass substrate according to the present invention, when the cartridge main body is made of a foamed resin series, the groove plate for fixing the glass substrate is simply configured in a detachable structure. Therefore, the cartridge cleaning process for reusing the package can be easily and perfectly implemented. Moreover, unlike the material of the main body of the case, the above detachable groove plate is made of a non-foamed material of a PET resin series, thereby optimally utilizing the advantages of the foamed resin, while avoiding the packaging box made of the existing foamed plastic. Has a slight scratch on the surface and surface contamination.

Reference will now be made in detail to the preferred embodiments of the invention, Wherever possible, the same reference numerals are used in the FIGS.

Hereinafter, in order to clearly explain the present invention, the configuration and features of the present invention will be described by exemplifying a rectangular parallelepiped cartridge body (10) composed of a pair of horizontal walls (13a, 13b) and a pair of vertical walls (14a, 14b). For reference, the above "horizontal wall" means a pair of mutually opposing walls in the peripheral portion of the cartridge body (10) arranged in a rectangular parallelepiped shape, and the above "vertical wall" means the remaining wall except the horizontal wall, and this The opposing walls are formed to extend perpendicularly from the horizontal walls to form mutually opposing structures.

Two pairs of protruding ends (11a, 11b/11c, 11d) are provided in the cartridge body (10) to detach the slot plate (20) therein. A pair of protruding ends (11a, 11b) are disposed on one side of the horizontal wall (13a), and the other pair of protruding ends (11c, 11d) are positioned on the other side of the horizontal wall (13b) and positioned to the other side The other pair of protruding ends (11c, 11d) on the horizontal wall (13b) are symmetrically arranged at each position opposite to the pair of protruding ends (11a, 11b) disposed on the horizontal wall (13a) on one side. form.

A pair of protruding ends (11a, 11b) disposed on the horizontal wall (13a) are formed along the height direction of each wall in the right/left section of the inner side of the horizontal wall (13a) It is preferable, and desirably, to form the protruding end in such a manner that it can extend in the height direction in a strip shape.

Also, the projecting ends (11a, 11b) are disposed to be separated from the inner sides of the vertical walls (14a, 14b) at a specific interval, whereby a concave is formed between the vertical walls (14a, 14b) and the corresponding projecting ends (11a to 11d). Slots (12a, 12b, 12c, 12d). The grooves (12a, 12b, 12c, 12d) correspond to slot plate slots for inserting/fixing the height direction (Y) edge of the slot plate (20) into the inside of the cartridge body (10). Therefore, a pair of protruding ends (11a, 11c) respectively provided on the one side of the pair of horizontal walls (13a, 13b) together with the vertical wall (14a) on the left side form a pair of slotted slots (12a, 12c), and a pair of protruding ends (11b, 11d) respectively provided on the sections on the other side together with the vertical wall (14b) on the right side form another pair of slotted slots (12b, 12d).

One of the main technical features of the package for the display glass substrate of the present invention is the fact that the glass substrate stored in the case is a groove plate which is detachably arranged by using a material different from that of the case body (10) ( 20) to support and fix. Therefore, the cartridge body (10) of the present invention does not directly contact the glass substrate, which is a factor that protects the glass substrate from the external environment and impact. Therefore, even if the cartridge body (10) is made of a foamed resin As a result, there will be no surface scratches and surface contamination caused by the fixing projections (21) made of a foamed material such as a package made of a conventional foamed plastic.

The cartridge body (10) is produced by a foam molding process using a foamed resin material, and as a desirable foamed resin material, expanded polyethylene (EPE) series resin or expanded polypropylene (expanded polyethylene) may be used. Expanded Polypropylene, EPP) series of resins. Therefore, the cartridge body (10) of the present invention is easy to transport because it is fundamentally light, and in particular, the cartridge body has good advantages such as absorbing a cushioning function of external impact or vibration generated when the package is transported.

The groove plate (20) of the present invention corresponds to a device for solving the weakness (i.e., deterioration of surface contamination and surface roughness) of a package made of a foamed plastic made only of an existing foamed resin. The groove plate (20) of the present invention is made of a material different from that of the cartridge body (10), that is, a non-foamed resin material, and is separated from the cartridge body (10) so that the groove plate can be assembled in a detachable manner.

Desirably, the groove plate (20) according to the first embodiment of Fig. 2 is configured in a rectangular plate-shaped member, whereby predetermined regions of the two height direction (Y) edges are used as the insertion portions (23a, 23b), and A glass substrate fixing portion is formed on one side of the remaining regions except the insertion portions (23a, 23b).

The two insertion portions (23a, 23b) of the slot plate (20) are fixedly contacted with the vertical wall (14b) by being inserted into a pair of slot plate slots (12b, 12d) provided on the cartridge body (10). Therefore, the protruding ends (11b, 11d) should be separated from the inner surface of the vertical wall (14b) by at least as much as the slot plate insertion portion in the width. The thickness of the fraction (23a, 23b).

The glass substrate fixing portion of the groove plate (20) is alternately composed of a plurality of fixing projections (21) and a plurality of substrate slots (22). The fixing projections (21) are protruded to extend in the height direction on the wall of one side of the groove plate (20), and each of the fixing projections (21) is separated to form a specific interval. In addition, each of the substrate slots (22) is formed by a separated space formed by a pair of mutually adjacent fixing projections (21).

The fixing projection (21) may be configured to have a rectangular cross-sectional configuration similar to that shown in FIG. 3(a) such that the inner portion of the substrate slot (22) (ie, the bottom side of the slot plate) and the outer portion (ie, The width of the open portion side is the same, or the fixing projection (21') may be configured similarly to the substantially trapezoidal sectional form shown in FIG. 3(b) such that the width thereof follows the slot from the substrate. The inner side portion of (22') is narrowed toward the outer portion.

Moreover, in the package of the present invention, when the groove plate (20) is inserted/assembled into the groove plate slots (12b, 12d), the glass substrate fixing portion is inserted and placed into a pair of protruding ends (11b, 11d) opposed to each other. In the space (K1) between, the fixed portion of the glass substrate can be completely exposed. Therefore, the horizontal direction (X) width of the glass substrate fixing portion formed on one side of the groove plate (20) should be smaller than or equal to the width of the space (K1) formed by the pair of protruding ends.

4 is a combined perspective view of a package for a display glass substrate in which a slot plate (20) according to a first embodiment of the present invention is mounted.

Similar to that shown in Figure 4, a pair of slot plates (20) are assembled to oppose each other within the cartridge body (10). By having two inserts (23a, 23b) Can be inserted and separated as it moves up and down along a pair of slotted slots (12b, 12d) disposed within the cartridge body (10), each of the slotted panels (20) being easily and removably The box body (10) is combined.

When a pair of groove plates (20) are completely assembled into the cartridge body (10), the glass substrate fixing portions of each of the groove plates (20) face each other, and two of the glass substrates stored in the cartridge body (10) After the vertical edges are individually inserted into the pair of substrate slots (22) of the opposite slot plates, the glass substrate is supported by the fixing protrusions (21), whereby the glass substrate is stored in the box body (10) and maintained Fixed state.

The package for a display glass substrate according to the present invention is mainly characterized in that the case main body (10) is made of a foamed resin series, and the groove plate (20) for supporting and fixing in substantial contact with the glass substrate is available from the case. The body (10) is detached, and the groove plates (20) are made of a non-foamed material. Therefore, the package of the present invention can minimize the disadvantages such as substrate contamination and surface scratches of the package made of the existing foamed plastic, which optimally utilizes the advantages of the foamed resin.

That is, the groove plate (20) according to the first embodiment of the present invention has characteristics made of a non-foamed material, and these non-foamed materials employ a non-foamed polymer resin. At this time, it is preferable to use a material which does not have an additive such as cerium (Si), a lubricant component, and the like during the production of the raw material, and specifically, has a very low oligomer elution by a stable molecular structure. (oligomer elution) (ie, organic solvent and natural separation) raw materials are desirable. Therefore, when the groove plate (20) of the present invention is configured, it is easy to melt in organic Resin series in solvents and easy to separate (such as oligomers of styrene or ethylene) are undesirable.

In view of the above mentioned points, the applicant conducted the test by applying various non-foamed resin series. Moreover, the test results indicate that it is desirable to form the groove plate (20) with a series of polyethylene terephthalate (PET) resins, and that amorphous PET (hereinafter referred to as "A-PET") is used. More desirable. Moreover, when the slot plate (20) is configured with the PET resin series, the product can be produced without a separate additive while minimizing the generation of dust and friction.

A-PET is amorphous PET having less than 5% amorphous, and thus represents a polymer resin produced by using 100% ethylene glycol (Ethylene Glycol, EG). Since A-PET is not crystallized, it is flexible and strong, and its strength does not deteriorate even at a low temperature.

Fig. 5 is a view for showing the analysis results of the surface components of the A-PET slot plate according to the present invention, and the following "Table 1" relates to the numerical analysis data of Fig. 5.

The measurement diagram of Figure 5 shows the root obtained by using the FT-IR test equipment. The result of the measurement of the surface composition of the grooved plate (20) made of A-PET material according to a preferred embodiment of the present invention.

For reference, the FT-IR test apparatus corresponds to a device that analyzes the surface composition as a peak of reading by illuminating the wavelength of the infrared region at one time and simultaneously detecting the data.

The vertical axis of the measurement map of Fig. 5 represents the infrared wavelength range, while the horizontal axis shows the number of absorption peaks, and the peak value means the maximum power. Similarly, Table 1 relates to test data for numerically quantizing the measurement map of FIG. 5, and respectively represents "E1" for the detected element, and "AN" is an atomic number for the periodic table of the corresponding element (atomic Numbers, "unn.C" is the weight ratio for the detected elements, "atom.C" is the atomic weight ratio for the detected elements, and the "error" shows the probability of not being the detected element.

The test data of Table 1 and the measurement chart of Figure 5 also show that only carbon (C) and oxygen (O) are present on the surface of the slot plate made of A-PET material in a weight ratio of approximately 6:4, and not Other materials such as bismuth (Si) or organic materials and particulates were detected, indicating that a very good surface state is maintained.

Therefore, the groove plate made of A-PET material can prevent fine scratches and substrate contamination caused by the transfer of particles and organic materials from the package made of the existing foamed plastic, and can ensure the glass substrate. Good surface quality.

Figure 6 is a measurement diagram for analyzing the surface composition of a glass substrate in contact with a groove plate made of a PET material of the present invention, and in the figure, the horizontal axis represents the measurement time, and the vertical axis represents the peak intensity, and is measured separately. "Glass-1 to Glass-4" has a total of four glass substrate surfaces.

As shown in the measurement results of Fig. 6, except for the water peaks, no other peak was detected from the surface of the glass substrate supported and packaged by the groove plate made of PET material, and it was confirmed that the surface was maintained well. quality. For reference, the water peak shown in FIG. 6 refers to a very small amount of water that transports gas, thereby corresponding to a factor independent of the surface quality of the glass substrate.

As indicated above, the package for a display glass substrate of the present invention can achieve an easy and perfect cleaning process for reusing the cartridge by simply separating the slot plate from the cartridge body (10) in a detachable configuration. In addition, it has a good advantage of preventing substrate contamination occurring during the packaging process of the glass substrate by forming the separated groove plate with PET or A-PET material.

Although the groove plate according to the above-mentioned preferred embodiment of the present invention is made of PET or A-PET material, the groove plate can exhibit an equivalent effect even if it is made of a PET-G material.

PET-G is an abbreviated form of "Polyethylene Terephthalate Glycol" which has weaker crystallization characteristics than A-PET by slowing the crystallization time and improves the molding process. Albino. For polyesters polymerized with terephthalic acid (TPA) and ethylene glycol (EG), PET-G replaces a certain amount of ethylene glycol by cyclohexanedimethanol (CHDM). (EG) delays crystallization, which improves transparency, processability, and material properties.

Fig. 7 is a view for showing the analysis results of the surface components of the PET-G groove plate according to the present invention, and the following "Table 2" relates to the numerical analysis data of Fig. 7.

The measurement chart of Fig. 7 shows the results of measurement of the surface composition of a grooved plate made of a PET-G material according to an embodiment of the present invention obtained by using an FT-IR test apparatus.

The horizontal axis of the measurement chart of Fig. 7 represents the infrared wavelength range, and the vertical axis shows the number of absorption peaks. Similarly, Table 2 relates to test data for numerically quantizing the measurement map of FIG. 7, and respectively represents "E1" for the detected element, "AN" is the atomic number for the periodic table of the corresponding element, " unn.C" is the weight ratio of the detected elements, "atom.C" is the atomic weight ratio for the detected element, and "error" indicates the probability of not detecting the element.

As shown in the test data of Table 2 and the measurement chart of Fig. 7, in addition to carbon (C) and oxygen (O), a bismuth (Si) component was detected on the surface of a grooved plate made of a PET-G material, However, no other organic materials or particles were detected. In other words, the slot plate made of PET-G material has a relatively low quality compared to the slot plate made of A-PET material. However, in addition to the bismuth component, other organic materials or particles do not exist and even 矽 itself is in a very small amount. In terms of existence, the PET-G channel plate can exhibit almost the same effect as the A-PET channel plate. Therefore, the groove plate made of PET-G material can also prevent the occurrence of fine scratches and substrate contamination due to the stain of transfer particles and organic materials in the package made of the existing foamed plastic, and can ensure the glass substrate. Good surface quality.
