- The present invention relates to a box for carrying substrates, and more particularly, to a box for carrying substrates in which substrates which are used for displays can be carried and kept.
- 2. Description of Related Art
- In general, glass substrates which are used for flat panel displays, such as a liquid crystal display (LCD), a plasma display panel (PDP) and an electroluminescent display (ELD), are carried and kept in the state in which they are received in a box. In particular, a plurality of glass substrates which are received in the box are supported in the erected position such that they do not contact each other.
- The box for carrying glass substrates (also referred to as a “glass substrate-carrying box”) includes a cuboid box body having an upper opening and a box cover which covers the upper portion of the box body. A plurality of protrusions and a plurality of substrate insertion grooves are alternately formed on and in the inner surfaces of a pair of walls of the box body which face each other, such that the protrusions and grooves extend in the height direction. In this fashion, the substrate insertion grooves are formed by the protrusions which protrude from the inner surfaces of the walls of the box body. Each of the glass substrates which are received in the box body is inserted into a pair of glass insertion grooves which face each other and pressed by two pairs of protrusions, such that it stays in the state in which it is received and held inside the box body.
- However, even though the glass substrates are carried using the glass substrate-carrying box, defects frequently occur due to reasons that are unclear during actual carriage of the glass substrates. For example, some glass substrates received inside the glass substrate-carrying box are broken or overlapped on each other.
- In order to minimize the occurrence of such defects, it is desperately required that an examination of the reasons and a mechanism for the occurrence of defects be performed.

box cover 220 has sidewalls 222 and acovering section 224 in order to cover and close the upper opening of thebox body 210. Firsttransparent windows 226 are formed in thecovering section 224 of thebox cover 220, such that the substrate-receiving space of thebox body 210 can be seen through the firsttransparent windows 226. - Since the first
transparent windows 226 are formed in thecovering section 224 of thebox cover 220, it is possible to observe the state of the substrates which are received and arranged in thebox body 210 whenbox cover 220 is placed over thebox body 210. Accordingly, when the substrates received in the box for carrying substrates according to this embodiment of the invention become defective, such as when, for example, the substrates have been broken or become overlapped on each other due to any reason during the actual practice of being carried, it is possible to examine reasons or a mechanism for defects. - The first
transparent windows 226 may be made of any transparent material through which the substrate-receiving space of thebox body 210 can be seen. However, considering the hardness of the firsttransparent windows 226 and a manufacturing cost thereof, it is preferred that the firsttransparent windows 226 be made of an acrylic material and have a thickness of 1.5 mm. -
FIG. 3 is a graph showing measurements of Vicker hardness depending on the material and thickness of the firsttransparent windows 226. As shown inFIG. 3 , it can be appreciated that the firsttransparent windows 226 made of an acrylic material and having a thickness of 1.5 mm have a Vicker hardness of about 17.6, which is higher than that made of an A-PET or G-PET material. Accordingly, the firsttransparent windows 226 can minimize the occurrence of scratches, thereby maintaining high transparency. - The first
transparent windows 226 can be formed in some portions of thecovering section 224 of thebox cover 220. In addition, the firsttransparent windows 226 can be a plurality of windows, in which case the firsttransparent windows 226 are preferably formed in the central portion and at both sides of the central portion of thecovering section 224. Since the firsttransparent windows 226 are formed in this way, it is possible to economically and accurately perceive the overlap and damaged positions of the substrates received in the box for carrying substrates according to the invention. - In addition, as shown in
FIG. 4 , the box for carrying substrates according to the second embodiment of the invention can also include asupport pad 228 which is coupled to the inner surface of thecovering section 224. Thesupport pad 228 has a plurality of support grooves into and by which the substrates received in thebox body 210 are inserted and held. - In this way, since the substrates are inserted into and held by the support grooves of the
support slots 228 coupled to the inner surface of thecovering section 224, it is possible to carry the substrates by holding them more firmly. - Preferably, the cross-section of the support grooves formed in the
support pad 228 has the shape of an upside-down “Y,” as shown inFIG. 5 . Since the cross-section of the support grooves of thesupport pad 228 has the shape of an upside-down “Y,” the substrates can be easily inserted into the support grooves. - When the first
transparent windows 226 are formed in some portions of thecovering section 224 of thebox cover 220, thesupport pad 228 is preferably coupled to the inner surface of thecovering section 224 in which the firsttransparent windows 226 are not formed. - In addition, the box for carrying substrates according to the second embodiment of the invention can also include
support slots 229 which are coupled to a pair of opposing inner surfaces of thesidewalls 222 of thebox cover 220. Each of thesupport slots 229 has a plurality of support grooves which supports the substrates received in thebox body 210. Since the substrates are inserted into and held by the support grooves of thesupport slots 229 which are configured as above, it is possible to carry the substrates by holding them more firmly. - As shown in
FIG. 6 , secondtransparent windows 227 can be formed in a pair of opposing sidewalls of the four sidewalls of thebox cover 220, such that both edges of the received substrates can be seen through the secondtransparent windows 227. - When the both edges of the substrates are monitored through the second
transparent windows 227, it is possible to more easily monitor reasons or a mechanism for the overlap or breakage of the edges of the substrates. - The second
transparent windows 227 are made of an acrylic material, and preferably have a thickness of about 1.5 mm. -
FIG. 7A shows a box cover according to the second embodiment of the invention, andFIG. 7B is a box cover of the related art.FIG. 8 is a graph comparing variations in the humidity with time of boxes for carrying substrates which include the box covers shown inFIG. 7A andFIG. 7B , andFIG. 9 is a graph comparing variations in the temperature with time of boxes for carrying substrates which include the box covers shown inFIG. 7A andFIG. 7B . In addition,FIG. 10 is a graph showing measurements of static electricity according to positions (A, B, C, D and E) of the box covers shown inFIG. 7A andFIG. 7B . Here, both of the box covers shown inFIG. 7A andFIG. 7B are made of a polypropylene material, and the first transparent windows shown inFIG. 7A are made of an acrylic material. - As shown in
FIG. 8 andFIG. 9 , it can be appreciated that the box for carrying substrates according to the second embodiment of the invention has temperature and humidity reliability at the same level as that of the box for carrying substrates of the related art which includes the box cover with no transparent windows. In addition, as shown inFIG. 10 , it can be appreciated that the surface resistance of the box cover according to the second embodiment of the invention is at the same level as that of the box cover of the related art. - That is, it can be appreciated that, when the first transparent windows are formed in the box cover according to the invention, the temperature/humidity characteristic and the surface resistance characteristic of the box cover are the same as those of the box cover of the related art and there is no problem in the box for carrying substrates according to the invention.
