[0051] The technical content and technical features of the present invention are described in detail below with reference to different embodiments and accompanying drawings. Figures 1 to 5 The telescopic storage mechanism 10 provided by the first preferred embodiment of the present invention is shown, which includes a plurality of trays 20 and at least two telescopic components 30. At least two telescopic components 30 connect two adjacent trays 20 together. The telescopic components 30 can be telescoped to change the distance between each tray 20. When the telescopic components 30 are in an extended state, the distance between the two adjacent trays 20 is the maximum. When the telescopic components 30 are in a compressed state, the distance between the two adjacent trays 20 is the minimum. Each tray 20 can be a regular polygon, such as a square or a regular octagon, etc. However, the shape of each tray 20 can be changed according to needs and there is no special limitation; each tray 20 can carry objects according to the situation, and the objects can be wafers, bowls, plates, or records, etc.

[0052] Please refer to Figures 2 and 3. The tray 20 includes a side opening 22 and a bottom opening 24. These two openings can be used to facilitate the robot arm or the operator to place an object such as a wafer 100 on the tray 20 or to remove the wafer 100 from the tray 20. The bottom opening 24 can be designed to be circular or other shapes, and can be adjusted according to the actual process requirements. In order to place the wafer 100 more stably in the tray 20, the tray 20 can further include a step structure 25. The step structure 25 includes a step side wall 251 and a step bottom 253. The step structure 25 can limit the horizontal movement of the wafer 100, thereby ensuring that the wafer 100 will not slip out or even be damaged due to transportation or process. The angle between the step side wall 251 and the tray 20 can be between 91 degrees and 179 degrees, and the angle between the step bottom 253 and the step side wall 251 is preferably less than 180 degrees.

[0053] After the wafer 100 is placed on the tray 20, the step structure 25 can effectively restrict the wafer 100, so that the wafer 100 cannot be easily moved horizontally, and the purpose of setting the step side wall 251 is to facilitate the access to the wafer 100, wherein the outermost edge projection area of ​​the step side wall 251 is slightly larger than the projection area of ​​the wafer 100, so that the outer edge of the wafer 100 is roughly against the step side wall 251 without touching the step bottom 253, thereby preventing the outer edge of the wafer 100 from colliding with the step structure 25. In addition, the projection area of ​​the inner edge of the step bottom 253 should not be too large or too small compared to the wafer 100, so that the wafer 100 can be easily taken and placed by the robot arm.

[0054] There are two telescopic components 30 between every two adjacent trays 20. The two telescopic components 30 are located on the left and right sides of the tray 20 respectively. Figure 1 In this embodiment, Figure 4 , 5 As shown, each telescopic assembly 30 includes a first side wall 31, a second side wall 32, a side wall connecting device 34 and a movement limiting device 36. The side wall connecting device 34 connects the first side wall 31 and the second side wall 32 together. The movement limiting device 36 is arranged on the outer sides of the first side wall 31 and the second side wall 32. The first side wall 31 is pivoted to one of the disk bodies 20, and the second side wall 32 is pivoted to another adjacent disk body 20. When the telescopic assembly 30 is in a compressed state, the first side wall 31 and the second side wall 32 can be close to each other. Figure 5As shown, the movement limiting device 36 has two arc portions 361, and the two arc portions 361 are respectively used for the first side wall 31 and the second side wall 32 to abut against each other, so as to limit the telescopic direction of each telescopic component 30. That is, when each telescopic component 30 is transformed from an extended state to a compressed state, the first side wall 31 and the second side wall 32 can be arranged according to the ">" ( Figure 5 The convex shape of the side wall connecting device 34 changes from a viewing angle. In other possible embodiments, the movement limiting device 36 may also be arranged on the inner side of the side wall connecting device 34 or have other structural changes, or may even be omitted. The structure of the side wall connecting device 34 is not limited, as long as the first side wall 31 and the second side wall 32 can be connected together. The manner in which the first side wall 31 and the second side wall 32 are pivotally mounted on the disk body 20 is not particularly limited. The pivot may penetrate the two adjacent disk bodies 20, the first side wall 31 and the second side wall 32 at the same time, or the first side wall 31 and the second side wall 32 may each have a pin that penetrates the pivot hole of the two adjacent disk bodies 20.

[0055] By extending and retracting the telescopic assembly 30 , when the distance between the two adjacent trays 20 becomes larger, it can help facilitate the placement and removal of the carried objects. When the distance between the two adjacent trays 20 becomes smaller, the overall volume of the telescopic storage mechanism 10 can be effectively reduced, thereby saving working space.

[0056] Figures 6 to 9 The figure shows a retractable storage mechanism 10A provided by a second preferred embodiment of the present invention, which has a structure substantially the same as that of the retractable storage mechanism 10, except that the side wall connection device 34A includes a first connection portion 341 and a second connection portion 345, wherein the first connection portion 341 is disposed on the first side wall 31 and the second connection portion 345 is disposed on the second side wall 32. Figure 8 , 9As shown, the first connection portion 341 has two first bodies 342, two pivot holes 343 and a receiving space 344. Each pivot hole 343 is respectively provided in each first body 342, and the receiving space 344 is located between the two first bodies 342. The second connection portion 345 has a second body 346 and two pivot posts 347. The second body 346 is received in the receiving space 344. The two pivot posts 347 extend from the second body 346 and extend into the two pivot holes 343. In this way, the side wall connection device 34A can connect the first side wall 31 and the second side wall 32 together. In addition, the two first bodies 342 of the first connecting portion 341 respectively have arc segments 342a, and the second connecting portion 345 is further provided with two grooves 345b, which are located on both sides of the second body 346. The two arc segments 342a are abutted against the two grooves 345b to form a movement limiting device 36A, and the movement limiting device 36A limits the telescopic direction of each telescopic assembly 30, that is, the first side wall 31 and the second side wall 32 can be arranged according to the ">" ( Figure 7 On the other hand, each of the two adjacent trays 20 has two telescopic components 30 located on two symmetrical sides of the tray 20. In other possible embodiments, the structures of the first connecting portion 341 and the second connecting portion 345 can be interchanged.

[0057] Figures 10 to 13 The third preferred embodiment of the present invention is a retractable storage mechanism 10B, which has a structure similar to that of the retractable storage mechanisms 10 and 10A, except that each retractable assembly 30B includes a first side wall 31B, a second side wall 32B and a side wall connecting device 34B, wherein the second side wall 32B and the first side wall 31B are pivotally mounted on the same tray 20, and the side wall connecting device 34B pivotally connects the second side wall 32B to the first side wall 31B pivotally mounted on another tray 20, and when the retractable assembly 30B is in a compressed state, the first side walls 31B of the retractable assembly 30B are brought close to each other and pressed against each other, and the second side walls 32B of the retractable assembly 30B are brought close to each other and pressed against each other (e.g., Fig.13 In this embodiment, reference may be made to Fig.11 The lower end 31B" of the first side wall 31B on the same plate body 20 is pivotally connected to the upper end 32B' of the second side wall 32B, and the lower end 32B" of the second side wall 32B is pivotally connected to the upper end 31B' of the first side wall 31B on another plate body 20. Fig.12The upper end 31B' of the first side wall 31B has a limiting track 310, and the lower end 32B" of the second side wall 32B has a limiting boss 320. The limiting boss 320 can extend into the limiting track 310 to form the side wall connecting device 34B, so that the first side wall 31B and the second side wall 32B are connected together. At the same time, since the limiting boss 320 can only move within the limiting track 310, the limiting boss 320 and the limiting track 310 also form a moving limiting device 36B, thereby limiting the telescopic direction of the telescopic component 30B. On the other hand, Fig.10 As shown, each of two adjacent trays 20 is provided with four telescopic components 30 located on two symmetrical sides of the tray 20 , and the first side wall 31B and the second side wall 32B are pivotally connected in the extension direction L1 of the tray 20 , parallel to the extension direction L0 of the side length of the tray 20 .

[0058] Fig.14 , 15 The figure shows a retractable storage mechanism 10C provided by the fourth preferred embodiment of the present invention, and its structure is roughly the same as the retractable storage mechanism 10B, except that the telescopic assembly 30 located on both sides of the tray body 20, its first side wall 31 and the second side wall 32 are pivotally connected to the extension direction L2 of the tray body 20, which is perpendicular to the extension direction L0 of the side length of the tray body 20.

[0059] Fig.16 , 17 The fifth preferred embodiment of the present invention provides a retractable storage mechanism 10D, which has a structure substantially the same as that of the retractable storage mechanism 10C, except that the retractable assembly 30 located on both sides of the tray body 20 has a first side wall 31 and a second side wall 32 pivotally connected to an extension direction L3 of the tray body 20, and is neither perpendicular nor parallel to an extension direction L0 of a side length of the tray body 20.

[0060] Please refer to Fig.18 , 19 The present invention further provides a storage box 50 for accommodating the retractable storage mechanisms 10, 10A, 10B, 10C, and 10D (hereinafter collectively referred to as 10) in the above-mentioned embodiments. The storage box 50 includes an upper cover 60, a lower cover 70, and a storage space 80. The lower cover 70 is located below the upper cover 60. The storage space 80 is located between the upper cover 60 and the lower cover 70. The upper cover 60 can be movably covered on the lower cover 70 up and down. The storage space 80 is used to accommodate the retractable storage mechanism 10. Fig.18 FIG. 5 is a schematic diagram showing the state of the storage box 50 when the telescopic assembly 30 is in a compressed state, that is, the upper cover 60 is covered on the lower cover 70. Fig.19The figure shows the state of the storage box 50 when the telescopic assembly 30 is in the extended state, that is, the upper cover 60 is separated from the lower cover 70. The appearance of the upper cover 60 and the lower cover 70 can be changed according to the shape of the tray body 20, and even the upper cover 60 can be only a flat plate; in addition, the storage box 50 can have a handle, which is provided on the upper cover 60 for manual or mechanical handling of the upper cover 60.

[0061] The upper cover 60 can be connected to the topmost tray 20 of the retractable storage mechanism 10, and the lower cover 70 can be connected to the bottommost tray 20 of the retractable storage mechanism 10. Fig. 20 , 21 In this embodiment, the upper cover 60 has eight upper limiting members 62, which are respectively arranged at the inner edges of the eight sides of the upper cover 60. The lower cover 70 also has eight lower limiting members 72, which are arranged at the inner edges of the eight sides of the lower cover 70. The upper limiting members 62 can directly or indirectly hook the topmost tray 20 of the retractable storage mechanism 10, and the lower limiting members 72 can directly or indirectly hook the bottommost tray 20 of the retractable storage mechanism 10. In this embodiment, each of the upper limiting members 62 has an upper limit portion 621, which is directly hooked with the topmost tray 20, and each of the lower limiting members 72 has a lower limit portion 721, which is directly hooked with the bottommost tray 20. In other possible embodiments, the number of the upper limiting member 62 and the lower limiting member 72 can be adjusted as needed, and the structure of the upper limiting member 62 and the lower limiting member 72 is not limited to this embodiment, as long as they can be connected to the upper cover 60 and the lower cover 70 respectively.

[0062] like Fig. 22As shown, the tray body 20, except for the top and bottom layers, has a side opening 21 for the lower limit portion 721 of the lower limit member 72 to pass through; when the upper cover 60 moves upward relative to the lower cover 70, the upper limit portion 621 of the upper limit member 62 of the upper cover 60 directly drives the tray body 20 at the top layer, so that the telescopic assembly 30 of the telescopic storage mechanism 10 changes from the compressed state to the extended state. In this way, each tray body 20 moves upward together and the distance between each tray body 20 increases, and the side opening 21 allows the lower limit member 72 to pass through, until the tray body 20 at the bottom layer is directly fixed by the lower limit portion 721 of the lower limit member 72 of the lower cover 70 and cannot move upward. At this time, the telescopic assembly 30 is in the extended state and the distance between two adjacent tray bodies 20 is the largest, and the objects carried on each tray body 20 can be conveniently taken and placed. Next, when the upper cover 60 moves downward relative to the lower cover 70, the upper cover 60 presses against the topmost plate body 20, whereby each plate body 20 moves downward together and the distance between each plate body 20 decreases, until the telescopic assembly 30 is in a compressed state and the distance between two adjacent plate bodies 20 is minimized. At this time, the overall volume of the telescopic storage mechanism 10 can be effectively reduced, thereby saving working space.

[0063] The objects can be taken and placed by manpower or mechanical arms without any special restrictions, and the upper cover 60 can be moved up and down by taking and placing the handle or directly taking and placing the upper cover 60. The top tray 20 and the bottom tray 20 may not carry objects depending on the situation.

[0064] Fig.23 The figure shows a state schematic diagram of the upper limiting member 62 indirectly connected to the topmost tray 20 of the telescopic storage mechanism 10 in other embodiments, that is, the upper limiting member 62 is pivotally connected to the first side wall 31 of the telescopic assembly 30. When the upper cover 60 moves upward, it can pull the first side wall 31, thereby driving the telescopic assembly 30 to extend; similarly, the lower limiting member 72 can also be indirectly connected to the bottommost tray 20 of the telescopic storage mechanism 10, that is, the lower limiting member 72 is pivotally connected to the second side wall 32 of the telescopic assembly 30 (not shown). In other possible embodiments, the upper limiting member 62 can be pivotally connected to the second side wall 32, and the lower limiting member 72 can be pivotally connected to the first side wall 31.

[0065] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of simple modifications, replacements or reductions of components within the technical scope disclosed in the present application, which should all fall within the protection scope of the present application.
