       [0001]    This is a division of U.S. application Ser. No. 13/379,009, filed on Dec. 17, 2011 and entitled “A Glass Substrate Storage and Transportation System and A Glass Substrate Storage Platform.” 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to a glass substrate storage and transportation field, and more particularly to a glass substrate storage and transportation system and a glass substrate storage platform, being capable of improving the space utilization rate and reducing the particle pollution on the glass substrate. 
         [0004]    2. Description of the Prior Art 
         [0005]    A traditional glass substrate storage and transportation system employs stockers and a stacker crane to transport glass substrates. Each stocker loads the glass cassettes, each of which accommodates a plurality of glass substrates. The stacker crane can transport the glass cassettes of each stocker for transporting the glass substrates. 
         [0006]    With the increasing of the size of the glass substrate and the production capacity, it means that the stocker needs to load the more and larger glass cassettes. And the stocker of the larger volume will take up more space. 
         [0007]    Moreover, the mechanical wear or other factors will result in the problem of the particle pollution within the stocker is serious. Because the glass substrates are horizontally placed in the glass cassette by the traditional way, the glass substrates are easy to be polluted after being put for a long time. Furthermore, when the stacker crane moves, it easily causes the dust due to the heavy weight thereof. According to the prior experience, because of the pollution within the stocker, the proportion of the defective products will continuously increase as time goes on. 
         [0008]    Hence, it is necessary to provide a glass substrate storage and transportation system and a glass substrate storage platform for solving the problem existing in the prior art.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0030]    The following description of every embodiment with reference to the accompanying drawings is used to exemplify a specific embodiment, which may be carried out in the present invention. Directional terms mentioned in the present invention, such as “top”, “bottom”, “front”, “back”, “left”, “right”, “inside”, “outside”, “side” etc., are only used with reference to the orientation of the accompanying drawings. Therefore, the used directional terms are intended to illustrate, but not to limit, the present invention. 
         [0031]      FIG. 1  shows a structural schematic view of a glass substrate storage platform used in a glass substrate storage and transportation system of the present invention. The storage platform  100  comprises a storage plate  120 , a plurality of retractable guideways  112  mounted on the storage plate  120 , and a plurality of storage housings  110  for receiving upright glass substrates  130 . The storage housings  110  are one-to-one corresponding to the retractable guideways  112  and each storage housing  110  is fixed on the corresponding retractable guideway  112 , so that the retractable guideways  112  are located on the storage plate  120 . Each storage housing  110  includes a fixed support plate  1101  for fixedly supporting the glass substrate  130 , a moveable support plate  1102  being parallel to the fixed support plate  1101  and for movably supporting the glass substrate  130 , and a bottom plate  1103  for connecting the fixed support plate  1101  and the moveable support plate  1102 . The fixed support plate  1101  and the moveable support plate  1102  are perpendicular to the storage plate  120 , and the bottom plate  1103  is parallel to the storage plate  120 . The bottom plate  1103  is fixed on the retractable guideway  112 , so that the storage housing  110  is fixed on the retractable guideway  112 . The storage plate  120  is provided with a plurality of air holes  121 . 
         [0032]    Referring to  FIG. 1 , when the glass substrate storage platform of the present invention is used, the glass substrate  130  is uprightly placed in the storage housing  110 . Because the storage housing  110  can be stretched or retracted by the retractable guideway  112 , the corresponding glass substrate  130  can be taken out or taken back. Therefore, the present invention need not specially reserve an operation space for the mechanical arm to transport the glass substrate  130 . The space between the two adjacent glass substrates  130  may be reduced to 10 mm, but the size of the original glass cassette is 30 mm For example, if taking a glass substrate with the size of 2500 mm×2200 mm for an example and taking twenty glass substrates  130  as a group, the length of the glass substrate storage platform of the present invention is only 250 mm (according to the thickness of the glass substrate  130 ) and the volume thereof is 2500 mm×2200 mm×250 mm But if adopting the original glass cassette, it will need the glass cassette with the size of 2500 mm×2200 mm×600 mm, and also need to think of the height of 300 mm of lifting the glass cassette by the stacker crane and the height of a frame of the glass cassette itself. The height of the glass cassette is generally at least 1000 mm. Obviously, the glass substrate storage platform of the present invention compared with the traditional glass cassette may save about three-quarter volume. In the present invention, the glass substrate  130  is a single substrate. In order to avoid a coated surface of the glass substrate  130  to contact with the fixed support plate, the glass substrate  130  may be store by the way of being incompletely upright (such as an angle of 70 to 80 degrees from horizontal), so that a back surface of the glass substrate  130  leans against the moveable support plate  1102 . But if the coated surface of the glass substrate  130  has been packed, the glass substrate  130  may be uprightly stored. 
         [0033]    Moreover, the storage plate  120  of the glass substrate storage platform of the present invention is provided with a plurality of air holes  121 . When the storage housing  110  is disposed on the storage plate  120 , these air holes  121  are located under the storage housing  110 . Because the glass substrate  130  is uprightly placed in the storage housing  110 , the dust particle is not easy to adhere to the surface of the glass substrate  130 . And besides, because the air flow between the glass substrates  130  is similar to the placed direction of the glass substrates  130 , the dust particle on the surface of the glass substrate  130  is easier to be cleared. In addition, when the retractable guideway  112  moves together with the storage housing  130  for picking out the glass substrate  130 , the falling dust particle cannot affect other glass substrates  130 . Accordingly, the glass substrate storage platform of the present invention may largely reduce the defective glass substrate resulted by the dust particle. 
         [0034]      FIGS. 2A and 2B  are structural schematic views of a first preferred embodiment of the glass substrate storage and transportation system of the present invention, wherein  FIG. 2A  is a schematic view showing that when one of the glass substrates is carried out and the glass substrate keeps an upright state, and  FIG. 2B  shows that the glass substrate of  FIG. 2A  is rotated and horizontally lies on a transportation platform. The glass substrate storage and transportation system comprises a storage platform  100  and a transportation platform  200 . The storage platform  100  is used to store the glass substrates  130 , and the transportation platform  200  is used to carry the glass substrates  130  out and in. 
         [0035]    The storage platform  100  shown in  FIGS. 2A and 2B  is similar to the storage platform  100  shown in  FIG. 1 , so the similar components adopt the same numerals. And the components not shown in  FIGS. 2A and 2B  may refer to the components and the numerals thereof shown in  FIG. 1 . To be brief, in the embodiment shown by  FIGS. 2A and 2B , the storage platform  100  comprises a storage plate  120 , a plurality of retractable guideways  112  and a plurality of storage housings  110 . Each storage housing  110  includes a fixed support plate  1101 , a moveable support plate  1102  and a bottom plate  1103 . The bottom plate  1103  of the storage housing  110  is fixed on the retractable guideway  112  so that it can move together with the retractable guideway  112  to be stretched from or retracted into the storage plate  120 . The retractable guideway  112  may be stretched or retracted along the direction (as a direction A shown in  FIG. 2A ) of carrying the glass substrate  130  out from and onto the storage platform  100 . The moveable support plate  1102  includes a moveable pivot (not shown in drawings), which can make the moveable support plate  1102  rotate relative to the bottom plate  1103 . The relative rotation angle thereof is 0 to 90 degrees. 
         [0036]    The transportation platform  200  comprises a feeding unit  210  for transporting the glass substrate  130  and a feeding guideway  220  for determining the transporting direction of the feeding unit  210 . The moveable support plate  1102  includes at least two support portions  1104  and an interval portion formed between the two support portions  1104 . The feeding unit  210  disposes a retaining portion  211 , which is corresponding to the interval portion  1105  and is used to hold the glass substrate  130 . 
         [0037]    When the retractable guideway  112  located on the storage plate  120  carries the storage housing  110  and the glass substrate  130  placed in the storage housing  110  to be stretched out toward the transportation platform  200  and leave from the storage plate  120  to arrive at the feeding unit  210  located on the feeding guideway  220  of the transportation platform  200 , the moveable support plate  1102  of the storage housing  110  is rotated relative to the transportation platform  200 . Because the glass substrate  130  leans against the moveable support plate  1102 , the glass substrate  130  will be rotated together with the moveable support plate  1102  until the glass substrate  130  lies on the retaining portion  211  of the feeding unit  210  of the transportation platform  200 , and then the glass substrate  130  will be removed by the feeding unit  210  to the demanded position of the worker. 
         [0038]    On the contrary, when the glass substrate  130  needs to be carried onto the storage plate  120 , the retractable guideway  112  located on the storage plate  120  takes the empty storage housing  110  to be stretched out toward the transportation platform  200  and leave from the storage plate  120  to arrive at an upper surface of the feeding guideway  220  of the transportation platform  200 , then the glass substrate  130  is transported onto the moveable support plate  1102  by the feeding unit  210  and the retaining portion  211  thereof. Now, rotating the moveable support plate  1102  can make the glass substrate  130  uprightly stand in the storage housing  110 . Finally, the retractable guideway  112  takes the storage housing  110  with the glass substrate  130  to return to the storage plate  120 . 
         [0039]    When the glass substrate storage and transportation system of the present invention is used, the specific implementation mode and the beneficial effect of the storage platform  100  is similar to those of the glass substrate storage platform shown in  FIG. 1 , so please refer to the embodiment of the glass substrate storage platform shown in  FIG. 1 . The transportation platform  200  does not adopt the stacker crane, but adopts the feeding unit  210  and the feeding guideway  220 , thereby largely reducing the failure rate of the equipment. 
         [0040]      FIGS. 3A to 3D  are structural schematic views of a second preferred embodiment of the glass substrate storage and transportation system of the present invention, wherein  FIG. 3A  is a schematic view showing that one of the glass substrates is carried out and now the glass substrate keeps an upright state,  FIG. 3B  is a schematic view showing that the glass substrate of  FIG. 3A  is rotated to lie on the transportation platform,  FIG. 3C  is a schematic view showing that one of the glass substrates is ready to be carried in and now the glass substrate keeps a lying state, and  FIG. 3D  is a schematic view showing that the glass substrate of  FIG. 3C  is rotated 90 degrees to uprightly stand on the transportation platform. The main difference between the first embodiment of  FIGS. 2A and 2B  and the second embodiment of  FIGS. 3A and 3B  is that: the second embodiment of  FIGS. 3A and 3B  employs two transportation platforms  200 ,  200 ′ to be responsible for carrying the glass substrate  130  out and in, respectively. 
         [0041]    Please refer to  FIGS. 3A and 3B  and simultaneously combine with the detail structures of the components of  FIGS. 1 and 2 , when the glass substrate  130  needs to be taken out, the storage housing  110  loaded with the glass substrate  130  can move together with the retractable guideway  112  to be stretched unto the transportation platform  200 . The retractable guideway  112  is mounted in a drawer cabinet, one fixed end thereof is connected to the storage plate  120 , and two moveable ends thereof are connected the bottom plate  1103 . When the retractable guideway  112  is stretched or retracted, only the moveable ends can make the retractable guideway  112  be stretched, but the fixed end can not move. The stretching and retracting movement of the retractable guideway  112  may be driven by a cylinder. The retractable guideway  112  can be stretched one segment by one segment, and it has some strength being enough for supporting the weight of the glass substrate  130 . Subsequently, the moveable support plate  1102  is rotated 90 degrees around the moveable pivot, so that the glass substrate  130  on the moveable support plate  1102  is placed onto the feeding unit  210  of the transportation platform  200  (as shown in  FIG. 3B ). Here, a servo motor can be employed to control the rotation angle and the rotation precision of the moveable pivot, and the mechanisms, such as a shaft coupling and so on can be employed to change the rotation direction of the moveable pivot of the moveable support plate  1102  for driving the moveable support plate  1102  to rotate. Now, the retaining portion  211  of the feeding unit  210  of the transportation platform  200  passes through the interval portion  1105  of the moveable support plate  1102  to hold the corresponding glass substrate  130 . Finally, the feeding unit  210  moves along the feeding guideway  220  to output the corresponding glass substrate  130  to an entry-exit opening, so that the worker may take away the glass substrate  130 . 
         [0042]    Please refer to  FIGS. 3C and 3D  and simultaneously combine with the detail structures of the components of  FIGS. 1 and 2 , when the glass substrate  130  needs to be carried in, the glass substrate  130  is placed onto the feeding unit  210  of the transportation platform  200 ′ and then is held by the retaining portion  211  of the feeding unit  210 . Now, the moveable support plate  1102  is parallel to the transportation platform  200 ′, so the feeding unit  210  can move along the feeding guideway  220  to transport the glass substrate  130  upon the moveable support plate  1102 , and the retaining portion  211  of the feeding unit  210  is located in the interval portion  1105  of the moveable support plate  1102 . Then, the moveable support plate  1102  can be rotated 90 degrees through the moveable pivot, so that the glass substrate  130  of the feeding unit  210  can uprightly stand in the storage housing  110  of the storage platform  100  (as shown in  FIG. 3D ). Here, the servo motor can be employed to control the rotation angle and the rotation precision of the moveable pivot, and the mechanisms, such as the shaft coupling and so on can be employed to change the rotation direction of the moveable pivot of the moveable support plate  1102  for driving the moveable support plate  1102  to rotate. Finally, the storage housing  110  loaded with the glass substrate  130  can carry the glass substrate  130  from the transportation platform  200 ′ to the storage platform  100 , thereby completing the carry-in operation of the glass substrate  130 . 
         [0043]    Thus, the carry-in and carry-out operation of the glass substrate  130  of the present invention may be completed on the same transportation platform  200  as shown in  FIGS. 2A and 2B , and also may be completed on the different transportation platforms  200 ,  200 ′ as shown in  FIGS. 3A and 3B . 
         [0044]    To be a preferred embodiment of the glass substrate storage and transportation system of the present invention, the feeding unit  210  disposes a fine-tuning wheel (not shown in drawings, and its position being the same as the above-mentioned retaining portion  211 ), which is corresponding to the interval portion  1105  and is used for holding the glass substrate  130  and adjusting the position of the glass substrate  130 . Here, the feeding unit  210  employs the fine-turning wheel to adjust the position of the glass substrate  130  so that making the carry-in and carry-out operation of the glass substrate  130  be more convenient and safe. 
         [0045]    In the structural schematic views of the second preferred embodiment of the glass substrate storage and transportation system of the present invention shown by  FIGS. 3A to 3D , the transportation platform specifically comprises a carry-out feeding unit for carrying the glass substrate out from the storage platform, a carry-out feeding guideway for determining the transporting direction of the carry-out feeding unit, a carry-in feeding unit for carrying the glass substrate into the storage platform, and a carry-in feeding guideway for determining the transporting direction of the carry-in feeding unit. The carry-in operation of the glass substrate is completed by the carry-in feeding unit and the carry-in feeding guideway, and the carry-out operation of the glass substrate is completed by the carry-out feeding unit and the carry-out feeding guideway. In the second preferred embodiment, the glass substrate storage and transportation system of the present invention can make the carry-in and carry-out operation of the glass substrate be simultaneously go on, and the exit opening and the entry opening may be located at different positions thereby avoiding the incorrect operations and largely improving the production efficiency of the manufacturer of the glass substrate. 
         [0046]    In a structural schematic view of a third preferred embodiment of the glass substrate storage and transportation system of the present invention shown by  FIG. 4 , the difference between it and the second embodiment shown by  FIG. 3  is that: a transportation platforms  400 ,  400 ′ shown in  FIG. 4  form a layer structure and there disposes a vertical guideway  430  between the transportation platforms  400 ,  400 ′. The vertical guideway  430  is located on one end of a feeding guideway  420  of each of the transportation platforms  400 ,  400 ′ and is used to make a feeding unit  410  move up and down. Because of disposing the vertical guideway  430 , all of the feeding units  410  may move up and down. Thus, in the regions with the same area, the present invention can dispose the multi-layer glass substrate storage and transportation system. The transportation platforms of two adjacent layers may be connected by the vertical guideway  430 , and there disposes an entry-exit opening of the glass substrate at an appropriate position of the vertical guideway  430  to make the worker carry the glass substrate out or in. The glass substrate storage and transportation system of the present invention adopts a three-dimensional, multi-layer and multi-row structure by the aid of the vertical guideway  430  to maximize the storage capacity thereby further saving the factory area taken up by the glass substrate storage and transportation system and enhancing the utilization rate of the factory area. 
         [0047]    The glass substrate storage and transportation system of the present invention may realize the computerized management of the glass substrate storage and transportation by a CIM (Computer Integrated Manufacturing).
