The present invention relates to a cassette for loading a glass substrate, and more particularly, to a cassette for loading a glass substrate for preventing friction and cracking occurring when the glass substrate for a liquid crystal display device is loaded on the cassette. will be.

BACKGROUND ART As an image display device, a liquid crystal display (LCD) is widely spotlighted due to its thinness, light weight, low power consumption, and the like.

In manufacturing such a liquid crystal display, a glass substrate, which is a material, is loaded using a cassette and then transported and moved.

Hereinafter, a conventional glass substrate stacking cassette will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view of a conventional glass substrate stacking cassette, and FIG. 2 is a detail view of the portion A in FIG.

As shown in FIG. 1, a conventional glass substrate stacking cassette has a side plate 11, a bottom plate 12, and a top plate 13 on which a guide 15 for loading a glass substrate is formed. And a stopper 14 for preventing the stacked glass substrate from flowing backward, and a handle 16 for allowing the operator to easily carry the cassette.

FIG. 2 is a detailed view of the portion A in FIG. 1, in which a plurality of guides 15 protrude in parallel to the side plate 11.

3 is a front view of another conventional glass substrate stacking cassette.

3 shows another conventional glass substrate stacking cassette, which has the same configuration as that in FIG. 1, but a plurality of guides 15 protrude symmetrically with respect to the side plate 11.

4 is a front view of another conventional glass substrate stacking cassette.

As shown in Fig. 4, another conventional glass substrate stacking cassette is an improvement over the glass substrate stacking cassettes of Figs. 1 and 3, and the guide 15 'is formed of the guides of Figs. It is formed longer than 15), and a protrusion is formed at the end of the guide 15 '. This improves the problem that warpage occurs due to the weight of the glass substrate 17 when the glass substrate 17 is loaded, and prevents static electricity generated as the contact portion of the glass substrate 17 and the guide 15 ′ widens. It is designed to reduce.

The effect | action of the conventional glass substrate loading cassette by the said structure is as follows.

When carrying and moving a liquid crystal display glass substrate, a process worker loads a glass substrate in a cassette by placing the glass substrate on the guide 15 formed in the side plate 11, respectively.

Once the glass substrates have been loaded in the cassette, the process worker lifts the cassette using the handle 16 and then moves the cassette with the glass substrate loaded by moving the front of the cassette slightly up so that the glass substrate does not spill. , Move it.

However, these conventional glass substrate stacking cassettes have a large friction because the guide is fixed when the glass substrate is loaded. As a result, static electricity is generated by the friction, and the side of the glass substrate is caused by friction between the glass substrate and the side plate. Abrasion occurs in the particles caused by the wear stagnant on the upper guide portion protruding to the outside has a problem causing a failure.

An object of the present invention is to solve this problem, to minimize the friction generated between the guide and the side plate and the glass substrate to uniformly align the glass substrate, suppress the generation of static electricity, thereby minimizing wear It is to reduce the generation of fine particles, and to prevent the particles from stagnation even when the particles are generated.

Glass substrate stacking cassette according to the present invention for achieving this object,

An upper plate facing the lower plate,

A plurality of supports supporting the two plates by being fixed to the edges of two surfaces corresponding to each other on the upper and lower plates,

A plurality of guides formed to protrude inwardly of the two substrates so that the substrate can be loaded on the support;

A roller fixed to the end of the guide so as to rotate,

Bottom,

An upper plate facing the lower plate,

A plurality of supports fixed to the edges of the two surfaces corresponding to the upper and lower plates to support the two plates,

A plurality of fixed and rotatable guides having a lower symmetrical protrusion so as to rotate about each of the supports,

Bottom,

The upper plate facing the lower plate,

A plurality of supports fixed to the edges of the two surfaces corresponding to the upper and lower plates to support the two plates,

A plurality of guides formed vertically inwardly of the two plates for loading a substrate on the plurality of supports, and having protrusions at ends;

It is fixed so as to rotate on the axis penetrating the center of the support and includes a roller formed corresponding to the plurality of guides.

In the glass substrate stacking cassette according to the present invention, since the roller which can rotate on the guide or the side plate is fixed, the occurrence of friction is significantly reduced when the glass substrate is loaded, and dust or particles are removed by removing the guide that protrudes outward. The space in which they are loaded disappears.

Then, embodiments of the glass substrate stacking cassette according to the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily practice.

FIG. 5 is a perspective view of a glass loading stack cassette according to a first embodiment of the present invention, and FIG. 6 is a detailed view of the portion B in FIG.

As shown in FIG. 5, the glass substrate stacking cassette according to the embodiment of the present invention is parallel to each other on the edges of two parallel surfaces of the base plate 22 having a cross shape including a support for maintaining a constant distance. Six side plates 21 are vertically fixed. The upper plate 23 corresponding to the bottom plate 22 is fixed to the end of the side plate 21 at the lower surface thereof, and the handle 26 is fixed to the surfaces facing each other at the upper side thereof. Here, the plurality of guide plates 25 for loading the glass substrates vertically inwardly facing each other are fixed to the plurality of side plates 21 at equal intervals in parallel with each other. The roller 28 which can rotate outward is fixed by the shaft. (See FIG. 6) And a stopper 24 is formed between the bottom plate 22 and the top plate 23 of one of the two surfaces that are not fixed to the side plate 21 to prevent slipping of the stacked glass substrate.

7 is a front view of a glass substrate stacking cassette according to a second embodiment of the present invention.

7 is a glass substrate stacking cassette according to the present invention shown in Figure 5 is the same configuration as when loaded in Figure 5, but the guide 25 'is formed longer than the guide 25 formed in Figure 5, A protrusion is formed at the end of the guide 25 '. This improves the problem that warpage occurs due to the weight of the glass substrate 27 when the glass substrate 27 is loaded, and prevents static electricity generated as the area where the glass substrate 27 and the guide 25 ′ widens. Guide 25 'with projection is designed to reduce. The plurality of rollers 28 'are formed to rotate between the side plates 21' so as to contact the side surfaces of the glass substrate 27 to reduce friction and prevent particles from being generated. The roller 28 'here has a number corresponding to each guide 25' and is fixed in position by an axis 29 through the center of the side plate 21 '. Of course, as shown in FIG. 5, it is also possible to fix the other roller to the end projection of the guide 25 ′ so as to rotate in contact with the lower surface of the glass substrate using another axis.

FIG. 8 is a front view of the glass substrate stacking cassette according to the third embodiment of the present invention, and FIG. 9 is a detailed view of the portion C in FIG.

FIG. 8 also has the same configuration as that in FIG. 5, but the side plates 21 are formed in a circular shape, and the positions are fixed so that a plurality of guides 25 can be rotated about the side plates 21 at equal intervals. . Here, the guide 25 is rotated in the direction in which the glass substrate is inserted, and each guide 25 is formed to have a symmetrically protruding portion at the bottom so that the glass substrate is loaded. (See Figure 9)

Therefore, in the glass substrate stacking cassette according to the present invention, since the roller which is rotatable to the guide or the side plate is fixed, not only the area of contact with the glass substrate and the guide when the glass substrate is loaded but also the friction caused by the rotation of the roller is rotated. This remarkable reduction reduces the alignment of the glass substrates, prevents the cassette from rolling and also reduces the generation of static electricity. And by removing the guide that protrudes to the outside there is an effect that can keep the cassette clean by reducing the dust or particles are loaded.
