V. Description of the invention (1) [Field of the invention] The present invention relates to a glass substrate box for a liquid crystal display, and more particularly to a glass substrate box for a liquid crystal display. The distance between the i glass substrates can be kept constant, and the robot arm can pick them up. This substrate has a large operating margin. [Previous technology] With the advancement of accompanying electronic technology, especially the prevalence of portable electronic products in daily life, the demand for thin, thin, short, and low power consumption displays is increasing. Liquid crystal displays (Liquid Crystal Display; LCD) are often used in such electronic products because they have the advantages of low power consumption, low heat generation, light weight, and non-light-emitting displays, and have even gradually replaced traditional ones. Cathode ray tube display. A liquid crystal display device usually includes a pair of substrates which are parallel to each other and are kept separated by a gap. The gap between the two substrates is generally referred to as a cell gap (ce e ^ ^ gap), and a liquid crystal material is placed in between. Liquid crystal materials change their optical characteristics with the applied electronic signals. Taking a thin film transistor liquid crystal display as an example, 'a plurality of pixel electrodes are arranged on a substrate to apply a predetermined sub-signal to the liquid crystal material, and a color chip is arranged on the other substrate' to thereby display the liquid crystal display. image. The substrate is made of transparent materials such as glass, acrylic (pMMA), and the like. In the manufacturing process of the liquid crystal display, the glass substrate needs to be moved or carried from one workbench to another workbench. The industry usually uses a glass substrate; 1 to carry and carry the glass substrate, and cooperate with a robotic arm to load and unload each glass substrate from the glass substrate box. As shown in Figures 丨 and 2 for carrying

The conventional substrate cassette 10 for a glass substrate includes a plurality of side plates 丨 丨 having a plurality of grooves 5 formed by the support members 17 for loading the glass substrate, a bottom plate 12 and a top plate 丨 3. The substrate box 丨 〇 further includes a Yu end plate 4 and two grips 16, wherein the distance between the end plate 14 and the side plate η is ", and the end plate 14 has a catch block 1 9 'when the glass substrate is loaded in the substrate box In the middle of the time, the stopper 19 of the end plate 14 can be used to prevent the glass substrate from shifting, and the handle 16 is used for convenient transportation of the substrate box. The distance α is fixed, about 1/4 of the distance between the two side plates 11. When using, the user inserts the glass substrate

Into the slot 15 of the side plate 11, and the glass substrate is loaded in the 10; As described above, when the glass substrate is inserted into the substrate cassette 10, the glass substrate is supported by the support member 17. However, due to the weight of the glass substrate, it will naturally bend downward, but the stopper 9 cannot match the bending of the glass substrate. As shown in Figures 3 and 313, Shikou shows the # curve of the glass substrate when the glass substrate does not have the stopper 19 and when the stopper 19 is provided. ⑹ As shown in FIG. 3a, when the glass substrate is bent by gravity, the falling distance of the glass substrate at the stopper 19 is dn. As shown in Figure

It is shown that when the glass substrate is supported by the stopper 19, the distance by which it is lowered is d, that is, the distance between the stopper 19 and the support member 17. As shown in Fig. 4, it shows a schematic cross-sectional view of the glass substrate along line 4-4 in the flutter diagram. The distance between the two glass substrates is 仳. In the manufacturing process of a liquid crystal display, a robot arm is inserted into the glass substrate spaced distance to extract the glass substrate. However, since the glass substrate is bent upward by the influence of the stopper 19, the margin that the robot arm can be inserted (the

When a thinner glass substrate is used, the strength of the 2-two-arm operation panel is lower, and the degree of bending is more *, making the robotic arm 1 = processing more difficult. Ding Zhizhi and U.S. Patent No. 6, 1 86, 344 B1 issued to Park et al. On February 13, 2001 " Cassette For Loading Glasses For Liquid Crystal

Duplay Device "also discloses a substrate case carrying a liquid crystal display. It has cantilever support to reduce the bending of the glass substrate, the static electricity generated by the glass substrate and the substrate case, and preventing the glass substrate from shifting. However, the cantilever support of the substrate cassette also caused the problem that the robot arm could be lowered. In the prior art, a substrate cassette without a stopper is also provided. However, in this type of substrate cassette, the glass substrate will rub against the end plate of the substrate cassette 'to increase the possibility of damage to the glass substrate. In the prior art, an open end fence type stopper is also provided. However, this type of finger block is easy to slide out the glass substrate due to the tilt of the substrate cassette during the transportation of the substrate E. Furthermore, as shown in FIG. 5, the prior art also provides a jagged stopper 22, which is composed of a series of inclined inclined surfaces 24, so that the glass substrate of the liquid crystal display can be placed on the inclined inclined surfaces 24. Anywhere. However, the glass substrate may also be inserted into the notch 26 under the inclined bevel 24, and the substrate may be distorted. In summary, there is a need to provide a substrate cassette that can be stably placed
