[0042] See Figures 1 to 5 This invention discloses a first embodiment of a substrate storage box 100 with a reinforced structure for storing multiple substrates 200, wherein the substrates 200 may, for example, be glass substrates. The substrate storage box 100 with the reinforced structure includes a box body 1, a front door panel 2, a locking unit 3, a handling and gripping structure 4, two top handles 5, a bottom reinforcing plate 6, multiple retaining structures 7, and two side handles 8. For example, the substrate storage box 100 with the reinforced structure uses high-strength, high-rigidity material (HPC, hydroxypropyl cellulose) as the main material and CFRP (carbon fiber reinforced polymer) as the reinforcing material.

[0043] The housing 1 has a top wall 11 and a bottom wall 12 that are vertically opposed along a vertical direction D1, two side walls 13 and a rear wall 14 connected between the top wall 11 and the bottom wall 12, two side plates 13' connected between the top wall 11 and the bottom wall 12 and located between the two side walls 13, and a plurality of side support portions 15 formed on the inner side of the two side plates 13'. The two side walls 13 are opposite each other along a left-right direction D2, and the rear wall 14 is located opposite each other in a front-back direction D3. The top wall 11, the bottom wall 12, the two side walls 13 and the rear wall 14 together define an accommodating space 16 having a front opening 161 for storing the substrate 200. The side support portions 15 are arranged along the vertical direction D1 in the accommodating space 16 and are used to support the substrate 200. The top wall 11 has a connecting frame 110. The top wall 11 may be provided with a plurality of top reinforcing ribs 111 made of CFRP as reinforcing material. The top reinforcing ribs 111 are respectively connected to the left and right sides and / or the rear side of the connecting frame 110.

[0044] The front door panel 2 is provided in the front opening 161 of the housing 1. The front door panel 2 has two return air grooves 21 facing rearward and spaced apart along the left-right direction D2, and multiple polished suction cup adsorption areas 22 facing forward and away from the accommodating space 16. Each of the return air grooves 21 is elongated and extends longitudinally along the vertical direction D1, located between the top and bottom of the front door panel 2. The front door panel 2 also has a rounded corner portion 23 surrounding each of the return air grooves 21. The rounded corner portion 23 guides the airflow, allowing air to flow smoothly into or out of the return air grooves 21. The suction cup adsorption areas 22 are used for adsorption by the suction cups of a robotic arm (not shown) to automatically remove the front door panel 2. In this first embodiment, the suction cup adsorption areas 22 are polished and enlarged to enhance the adsorption force between the suction cups and the adsorption area. The polishing method is mirror polishing with an arithmetic mean roughness (Ra) of 0.01~0.04 micrometers, and the area of ​​each suction cup adsorption area 22 is 70 square millimeters.

[0045] The locking unit 3 is disposed between the housing 1 and the front door panel 2, and is used to lock the front door panel 2 to the housing 1. In this first embodiment, the locking unit 3 has a plurality of locking sliders 31 disposed on the front door panel 2, a plurality of operating members 32 disposed on the front door panel 2 for controlling the locking sliders 31, and a plurality of locking grooves 33 formed on the housing 1 and corresponding to the locking sliders 31. By operating the operating members 32, the locking sliders 31 can be inserted into the locking grooves 33 to achieve the purpose of locking the front door panel 2 to the housing 1. In this first embodiment, there are eight locking sliders 31 and eight locking grooves 33, and four operating members 32. The operating members 32 and the locking sliders 31 are controlled in a one-to-two manner, but this is not a limitation.

[0046] The handling and gripping structure 4 is located on the connecting frame 110 of the top wall 11 of the box body 1 and has a surrounding wall 401 and a handling reinforcing rib 41 connected to the surrounding wall 401. In this first embodiment, the handling and gripping structure 4 is square, and the handling reinforcing rib 41 is integrally formed on the top of the handling and gripping structure 4 near the front side and is made of CFRP material. The handling reinforcing rib 41 is long rib shaped and its length extends along the left-right direction D2.

[0047] The two top handles 5 are located on the top wall 11 of the box body 1 and are for people to grip. Specifically, the two top handles 5 are made of high strength and high rigidity material (HPC), and the structure is strengthened by widening and increasing curvature to reduce deformation.

[0048] The bottom reinforcing plate 6 is disposed on the bottom wall 12 of the box body 1, and has a plate body 60, a surrounding wall 61 protruding from the top surface of the plate body 60, a rear positioning part 62 disposed on the plate body 60, two front positioning parts 63 disposed on the plate body 60, a first bottom reinforcing rib 64, and a second bottom reinforcing rib 65. The plate body 60 has a plate length L1 along the left-right direction D2. The first bottom reinforcing rib 64 is disposed on the plate body 60 and is located between the rear positioning part 62 and the surrounding wall 61. The first bottom reinforcing rib 64 is elongated and extends along the left-right direction D2. The first bottom reinforcing rib 64 has a rib length L2 along the left-right direction D2. The rib length L2 is between two-thirds of the plate length L1 and one time the plate length L1. The second bottom reinforcing rib 65 is disposed on the plate body 60 and connects the rear positioning part 62, the front positioning part 63, and the first bottom reinforcing rib 64. The second bottom reinforcing rib 65 is radially arranged. In this first embodiment, the first bottom reinforcing rib 64 is made of CFRP material. Preferably, both the first bottom reinforcing rib 64 and the second bottom reinforcing rib 65 are made of CFRP material. The rear positioning part 62 and the front positioning part 63 are used to respectively engage with three kinematic coupling pins (KCPs) of a loading / unloading port.

[0049] The retaining structure 7 is disposed on the rear side of the front door panel 2 and the front side of the rear wall 14 of the housing 1, and is used to maintain the position of the substrate 200 in the front-rear direction D3 and reduce the vibration of the substrate 200. In this first embodiment, there are four retaining structures 7 extending vertically, with two retaining structures 7 disposed on the front door panel 2 and the other two on the rear wall 14. Specifically, each retaining structure 7 has a mounting portion 71 disposed on the front door panel 2 or the rear wall 14 of the housing 1, a retaining portion 72 for the substrate 200 to abut against, and a plurality of elastic connecting arms 73 connecting the mounting portion and the retaining portion, for example, in an S-shaped wave pattern. In this first embodiment, the retaining portion 72 is a flat, elongated plate.

[0050] The two side handles 8 are located on the outer surfaces of the two side walls 13 of the box body 1. One end of each side handle 8 is connected to the two side walls 13 of the box body 1 near the top wall 11, and the other end is connected to the bottom reinforcing plate 6.

[0051] See Figures 6 to 9The second embodiment of the substrate storage box 100 with a reinforced structure of the present invention differs from the first embodiment in that the box body 1 in this second embodiment does not have a side plate 13' (see...). Figure 4 The side support portion 15 for supporting the substrate 200 is formed directly inside the two side walls 13. Additionally, the substrate storage box 100 with the reinforced structure includes two transport gripping structures 4 arranged at intervals along the left-right direction D2. Each of the described handling and gripping structures 4 has a gripping frame 402 connected to the top wall 11, a plurality of first handling reinforcing ribs 42 connected between the top wall 11 and the gripping frame 402, and a plurality of second handling reinforcing ribs 43 extending downward from the gripping frame 402 to the corresponding side wall 13 and connected between the gripping frame 402 and the corresponding side wall 13. The first handling reinforcing ribs 42 and the second handling reinforcing ribs 43 can respectively reduce the deformation of the top wall 11 and the two side walls 13. In particular, the first handling reinforcing ribs 42 can be integrally formed with the top wall 11, and the second handling reinforcing ribs 43 can be integrally formed with the gripping frame 402 and the side walls 13, which can further enhance the deformation resistance of the top wall 11 and the side walls 13. The first handling reinforcing ribs 42 and the second handling reinforcing ribs 43 are each made of CFRP material. In some embodiments, the second transport reinforcing rib 43, the gripping frame 402, and the box body 1 are integrally formed; in some embodiments, the first transport reinforcing rib 42, the gripping frame 402, and the box body 1 are integrally formed; in some embodiments, the first transport reinforcing rib 42, the gripping frame 402, the box body 1, and the second transport reinforcing rib 43 are integrally formed.

[0052] Furthermore, in this second embodiment, the two retaining structures 7 disposed on the front door panel 2 are located closer to the center in the left-right direction D2, and the two retaining structures 7 disposed on the rear wall 14 are also located closer to the center in the left-right direction D2. In this second embodiment, the number of the locking slider 31 and the locking groove 33 are six each, and the number of the operating members 32 is two (see...). Figure 12 Furthermore, the operating element 32 and the locking slider 31 are controlled in a one-to-three manner, but this is not a limitation.

[0053] See Figure 10 The third embodiment of the substrate storage box 100 with a reinforced structure of the present invention differs from the second embodiment in that the height of the first transport reinforcing rib 42 of each of the transport gripping structures 4 is relatively low.

[0054] See Figures 11 to 14The fourth embodiment of the substrate storage box 100 with reinforced structure of the present invention differs from the second embodiment in that each of the transport gripping structures 4 only has the second transport reinforcing rib 43 connected to the corresponding side wall 13. Furthermore, in this fourth embodiment, the two retaining structures 7 disposed on the front door panel 2 are offset towards the edge of the front door panel 2 in the left-right direction D2, and the two retaining structures 7 disposed on the rear wall 14 are also offset towards the edge of the rear wall 14 in the left-right direction D2.

[0055] See Figures 15 to 17 The fifth embodiment of the substrate storage box 100 with reinforced structure of the present invention differs from the fourth embodiment in that, in this fifth embodiment, the box body 1 has the two side plates 13', and the side support portion 15 is formed on the inner side of the two side plates 13'. Furthermore, although the two retaining structures 7 provided on the rear wall 14 are also biased towards the edge of the rear wall 14 in the left-right direction D2, they are closer to the center than in the fourth embodiment. Additionally, in this fifth embodiment, the retaining portion 72' of each retaining structure 7 provided on the rear wall 14 is not a flat, elongated plate, but rather a V-shaped elongated column with a V-shaped cross-section, and the retaining portion 72' has a relief recess 721 located at the turning point to avoid the sharp corner of the substrate 200.

[0056] In summary, the present invention, through the transport reinforcing ribs of the transport gripping structure 4 and the bottom reinforcing ribs of the bottom reinforcing plate 6, can strengthen the structural strength of the substrate storage box 100 with the reinforced structure that simultaneously loads the substrate 200, and prevent the substrate storage box 100 with the reinforced structure from deforming due to the excessive weight of the substrate 200.

[0057] The above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
