Description

Technical Field

[0001] The present invention relates to a substrate container capable of stacking a plurality of substrates in layers, and particularly to a substrate container having an adjustable stop assembly that can be applied generally to substrates of different lengths by easy and rapid adjustment.

Background Art

[0002] In the manufacturing processes of semiconductors and electronic circuits, etc., generally, a substrate container is used to transport a plurality of substrates (e.g., wafers and circuit boards), thereby stably transporting each substrate to different manufacturing stations. By doing so, it is possible to prevent each substrate from colliding and being damaged during transportation. A general substrate container mainly includes a mounting box and a set of support frames. These support frames are attached inside the mounting box and are used to stack each substrate in layers, and often, a stop member for positioning each substrate and preventing its swaying in the front-rear direction is installed at the end of each support frame.

[0003] However, when each substrate is not in the mass production stage but still in the development stage or the test stage, the size and specifications of each substrate are often finely adjusted according to the improvement and optimization of the manufacturing process. Therefore, in order to ensure that no swaying occurs in the front-rear direction when arranging each substrate, it is necessary to prepare support frames of different sizes according to substrates of different lengths. That is, it is necessary to manufacture support frames of various sizes, which not only causes a significant increase in manufacturing costs and inventory management problems but is also very inconvenient and time-consuming when removing and replacing each support frame. Therefore, there is an urgent need to design a substrate container that can be applied generally to substrates of different lengths by easy and rapid adjustment.

[0004] In view of the above, the inventor of the present invention has earnestly studied to solve the above-mentioned drawbacks of the prior art, and also utilized theory to propose the present invention that can solve the above-mentioned drawbacks.

[0031] A detailed description and technical content of the present invention will be made clearer by referring to the drawings attached below. However, please understand that the drawings are for illustrative purposes only and do not limit the present invention.

[0032] The present invention provides a substrate container having an adjustable stop assembly, which is used to hold multiple substrates A, such as wafers, glass substrates, or PCB circuit boards. As shown in Figures 1 to 3, the substrate container having an adjustable stop assembly in the present invention mainly comprises a box body 10, a pair of side carriers 20, and at least one adjustable stop assembly 30. In this embodiment, the number of adjustable stop assemblies 30 is equal to the number of corresponding side carriers 20, i.e., two. However, the present invention is not limited thereto, and for the sake of brevity, the following description will be based on a single adjustable stop assembly 30, but it is assumed that the number of adjustable stop assemblies 30 in the present invention is not limited to one.

[0033] In this embodiment, the box body 10 is generally a hollow rectangular prism, but the present invention is not limited thereto. The box body 10 has a storage groove 11, an opening side 12, and a closing side 13. Specifically, the opening side 12 and the closing side 13 are located on opposite front and rear sides of the storage groove 11, and the storage groove 11 can communicate with the outside space via the opening side 12.

[0034] Each side carrier 20 is installed on opposite left and right sides within the storage groove 11, and each side carrier 20 is located between the opening side 12 and the closing side 13. More specifically, each side carrier 20 is parallel to each other and is positioned perpendicularly between the opening side 12 and the closing side 13. Each side carrier 20 has a plurality of support plates 21 for placing each of the base materials A. In each side carrier 20, each support plate 21 protrudes from one side carrier 20 toward the other side carrier 20 and is positioned parallel to each other. Specifically, each support plate 21 is elongated and both ends face the opening side 12 and the closing side 13, respectively, and each support plate 21 of each side carrier 20 is positioned sequentially parallel to each other along the vertical direction. As a result, by placing the opposing sides of each base material A on the corresponding support plates 21 in each side carrier 20, each base material A can be arranged in layers between the side carriers 20.

[0035] The adjustable stop assembly 30 is positioned on the closing side 13 to correspond to one of the side carriers 20. Specifically, in this embodiment, each set of adjustable stop assemblies 30 corresponds to one of the side carriers 20, and is therefore positioned on both the left and right sides of the closing side 13. The adjustable stop assembly 30 includes a rotating rod 31 and a positioning mechanism 32.

[0036] In this embodiment, each rotating rod 31 is rotatably pivoted to the corresponding side carrier 20; however, the present invention is not limited thereto, and for example, each rotating rod 31 may be rotatably pivoted inside the box body 10, where each rotating rod 31 is positioned on the closing side 13 corresponding to each side carrier 20. A pair of pivot plates 22 are provided on one side of each adjustable stop assembly 30 facing the closing side 13 of the side carrier 20. Each rotating rod 31 is pivoted to and positioned between the corresponding pivot plates 22. Specifically, each pivot plate 22 has a pivot hole 221, and each end of each rotating rod 31 has a protruding pivot shaft 311, and each pivot shaft 311 of each rotating rod 31 is pivotally mounted in the respective pivot hole 221 of the corresponding pivot plate 22, thereby allowing it to rotate relative to the corresponding side carrier 20. Furthermore, each pivot plate 22 has a mounting groove 222, and the mounting groove 222 of each pivot plate 22 is in communication with a pivot hole 221. As a result, each pivot shaft 311 can slide through the mounting groove 222 and pivotally attach to each pivot hole 221, thereby facilitating the attachment of the rotating rod 31. The rotating rod 31 mainly includes a body 312, which has an axis 313 and a plurality of stop portions 314. Each of the pivot shafts 311 is installed at opposite ends of the body 312. Each stop portion 314 is arranged on the outer edge of the body 312 so as to radiate from the axis 313. In this embodiment, there are two stop portions 314, but in other embodiments, there can be three or more depending on the size of the base material A, and therefore the present invention does not impose many limitations thereon. Each stop portion 314 is plate-shaped, and at least two of these stop portions 314 have different stop thicknesses t. In other words, when designing these stoppers 314, different stopper thicknesses t can be designed according to the different lengths of the base material A.

[0037] To facilitate user operation, each positioning mechanism 32 in this embodiment is installed on the top of each side carrier 20. However, the present invention is not limited thereto. For example, each positioning mechanism 32 may be mounted inside the box body 10, where each positioning mechanism 32 is simply positioned on the closing side 13 corresponding to each side carrier 20. The positioning mechanism 32 can be switched between a positioning position S1 and an adjustment position S2, meaning the user can switch the state of the positioning mechanism 32 as needed. Specifically, as shown in Figures 3 to 5, when the positioning mechanism 32 is in the positioning position S1, the positioning mechanism 32 fixes the corresponding rotating rod 31 so that the rotating rod 31 cannot rotate, and one of the stopper parts 314 on the rotating rod 31 abuts against one side of the corresponding side carrier 20 facing the closing side 13, stopping it and preventing the base material A from being further pushed towards the closing side 13. As shown in Figure 6, when the positioning mechanism 32 is in the adjustment position S2, the positioning mechanism 32 releases the corresponding rotating rod 31, allowing the rotating rod 31 to rotate around the axis 313, thereby enabling the user to rotate the rotating rod 31 to the desired position.

[0038] Furthermore, as shown in Figures 3 and 4, each positioning mechanism 32 in this embodiment mainly includes a shift lever 321. The shift lever 321 is pivotally mounted on the corresponding side carrier 20, that is, in this embodiment, the shift lever 321 is pivotally mounted on the top of the corresponding side carrier 20. Therefore, by pivoting the shift lever 321 on the side carrier 20, the user can move the shift lever 321 to adjust its position and further switch between the positioning position S1 and the adjustment position S2. In addition, each positioning mechanism 32 in this embodiment further includes a torsion spring 322. The side carrier 20 of each adjustable stop assembly 30 has a fixing block 23. Specifically, each fixing block 23 is installed on the top of the corresponding side carrier 20 and is positioned adjacent to the closing side 13. Both ends of the torsion spring 322 in each positioning mechanism 32 are fixed to the fixing block 23 and the shift lever 321, respectively, thereby using the elasticity of the torsion spring 322 itself to apply a torsional force to the shift lever 321 and rotate it to the positioning position S1. Therefore, when a user attempts to adjust the rotating rod 31, they only need to apply an external force slightly greater than the torsional force to rotate the shift lever 321 to the adjustment position S2. Furthermore, after adjusting the rotating rod 31 to the desired position, the elasticity of the torsion spring 322 itself can be used to return the shift lever 321 to the positioning position S1. In this embodiment, the fixing blocks 23 of each side carrier 20 are T-shaped projections arranged facing each other, thereby locking one end of the torsion spring 322 between the T-shaped projections of the fixing blocks 23. However, the shape of the fixing blocks 23 in this invention is not limited to this.

[0039] Furthermore, in order to prevent the rotating rod 31 of the positioning mechanism 32 from rotating due to external forces, vibrations, shocks, or shaking when the positioning mechanism 32 is in position S1, the shift lever 321 in this embodiment has a positioning fitting block 3211, and the rotating rod 31 has a plurality of positioning fitting grooves 315. The positioning fitting block 3211 can fix the position of the rotating rod 31 by selectively engaging with one of the positioning fitting grooves 315, thereby preventing the rotating rod 31 from rotating when the positioning mechanism 32 is in position S1. Specifically, each positioning fitting groove 315 corresponding to each stop part 314 is arranged on the pivot plate 22 corresponding to the positioning mechanism 32, and therefore the positioning fitting block 3211 can be engaged with any positioning fitting groove 315 corresponding to any stop part 314. In other words, when the positioning mechanism 32 is in positioning position S1, the positioning fitting block 3211 selectively engages in one of the positioning fitting grooves 315, thereby allowing the required stopper 314 to rotate to the required position and then fix the position of the rotating rod 31 via the positioning fitting block 3211. Furthermore, when the positioning mechanism 32 is in adjustment position S2, the positioning fitting block 3211 disengages from each positioning fitting groove 315, thereby allowing the user to rotate the rotating rod 31 to adjust the position of each stopper 314.

[0040] As shown in Figures 9 to 11, in another embodiment of the present invention, the main difference is that the positioning mechanism 32 includes a compression spring 323, which is described in detail below. In this embodiment, the compression spring 323 of the positioning mechanism 32 is installed at the top of the rotating rod 31; however, the present invention is not limited thereto, and it may be installed at any one end of the rotating rod 31. One end of the body 312 of the rotating rod 31, away from the compression spring 323, has a plurality of positioning blocks 316, each positioning block 316 arranged to correspond to each stop 314. The pivot plate 22 of the side carrier 20, away from the compression spring 323, has a plurality of positioning holes 223 corresponding to each positioning block 316. In this embodiment, each pivot shaft 311 of the rotating rod 31 is pivotally mounted in each pivot hole 221 of each pivot plate 22, thereby allowing it to rotate relative to the side carrier 20. The compression spring 323 of the positioning mechanism 32 is fitted onto the pivot shaft 311 at the top of the rotating rod 31, and both ends of the compression spring 323 elastically contact the top of the body 312 of the rotating rod 31 and the corresponding pivot plate 22, respectively. This allows the elasticity of the compression spring 323 itself to apply an elastic force to the rotating rod 31 toward the bottom of the housing groove 11. Therefore, as shown in Figure 10, when the positioning mechanism 32 is in the positioning position S1, the elastic force applied by the compression spring 323 to the rotating rod 31 causes each positioning block 316 to be housed in its respective positioning hole 223, thereby fixing the rotating rod 31 to the side carrier 20 and preventing it from rotating. As shown in Figure 11, when a user attempts to adjust the rotating rod 31, they only need to apply an external force slightly greater than the elasticity to translate the rotating rod 31 upward and position the positioning mechanism 32 at the adjustment position S2 (that is, the compression spring 323 of the positioning mechanism 32 is compressed and shortened). At this time, each positioning block 316 of the rotating rod 31 detaches from each positioning hole 223 of the side carrier 20, thereby allowing the user to adjust the required stopper 314 to the required position by rotating the rotating rod 31.

[0041] As shown in Figures 3 and 5, in each rotating rod 31, at least one stopper 314 is positioned perpendicular to each support plate 21 of the corresponding side carrier 20, thereby contacting and stopping one side of the corresponding side carrier 20 facing the closing side 13. Also, as shown in Figure 3, at least one stopper 314 has a plurality of contact blocks 3141 corresponding to each support plate 21, thereby increasing the stopping thickness t of the stopper 314. Specifically, each contact block 3141 extends outward toward each support plate 21 to increase the stopping thickness t, however, the present invention is not limited thereto. A contact guide slope 3142 is formed on one side of each contact block 3141 facing the positioning mechanism 32, thereby functioning as a guide member when each base material A is positioned, preventing snagging and damage. In addition, each support plate 21 has a pair of support protrusions 211. Each support projection 211 of each support plate 21 is installed on both the front and rear sides of the support plate 21 so as to correspond to the opening side 12 and the closing side 13, respectively. A support guide slope 2111 is formed on one side of each support projection 211 facing the opening side 12, so that it can function as a guide member when each base material A is pushed between each side carrier 20, preventing snagging and damage. In this embodiment, support guide slopes 2111 are formed on both the side of each support projection 211 facing the opening side 12 and the side facing the closing side 13, so that it can function as a guide member when each base material A is pushed between each side carrier 20 and when it is removed from there, preventing snagging and damage. In addition, a mounting guide slope 24 is formed between each side carrier 20 and each corresponding support plate 21. Specifically, each mounting guide slope 24 faces the top of the corresponding side carrier 20, thereby functioning as a guide member when each base material A is placed on the corresponding support plate 21, preventing snagging and damage, and allowing it to be stably placed on the corresponding support plate 21.

[0042] Furthermore, as shown in Figures 1, 2, and 12, the box body 10 has a pair of position-restricting grooves 14 and a pair of position-restricting locking blocks 15. Each position-restricting groove 14 is located on both sides (or near both sides) of the housing groove 11, corresponding to the housing groove 11, and extends from the opening side 12 to the closing side 13. Each side carrier 20 has a positioning rib 25. Specifically, each positioning rib 25 is located at the top of the corresponding side carrier 20 and is adjacent to the opening side 12 of the box body 10. As a result, each positioning rib 25 of each side carrier 20 is housed in each position-restricting groove 14 of the box body 10, restricting each side carrier 20 and preventing it from swaying from side to side. Each position-restricting locking block 15 is also located on both sides (or near both sides) of the housing groove 11, corresponding to the housing groove 11, and extends from the closing side 13 to the opening side 12. Each side carrier 20 has a positioning projection 26. Specifically, each positioning projection 26 is located on the top of the corresponding side carrier 20 and adjacent to the closing side 13 of the box body 10. This allows each positioning projection 26 of each side carrier 20 to engage with each position limiting locking block 15 of the box body 10, thereby restricting each side carrier 20 from swaying from side to side and preventing each side carrier 20 from being pushed further into the closing side 13. Furthermore, the base container having an adjustable stop assembly in this invention further includes a plurality of bolts 40. The bottom of each side carrier 20 has a pair of connecting parts 27. In this embodiment, each connecting part 27 of each side carrier 20 is positioned adjacent to the opening side 12 and the closing side 13, respectively, but the invention is not limited thereto. Each bolt 40 is connected through to the bottom of the box body 10 and screwed into a threaded hole (not shown) inside each connecting part 27, thereby fixing each side carrier 20 inside the box body 10.

[0043] The present invention provides a substrate container having an adjustable stop assembly, and by positioning the adjustable stop assembly 30 on the closing side 13 to correspond to one of its side carriers 20, the rotating rod 31 of the adjustable stop assembly 30 is arranged radially around the axis 313 and has a plurality of stop portions 314, each with a different stop thickness t, and the positioning mechanism 32 can switch between a positioning position S1 and an adjustment position S2 to fix or release the rotating rod 31, thereby allowing one of the stop portions 314 to abut against one side of the corresponding side carrier 20 facing the closing side 13 and stop it, or the rotating rod 31 to rotate around the axis 313. Therefore, by easily and quickly adjusting the adjustable stop assembly 30, a stop portion 314 with a desired stop thickness t can abut against one side of the side carrier 20 and stop it, and each side carrier 20 can be universally applied to each of the substrates A of different lengths.
