Description

Substrate container with adjustable stop assembly This disclosure relates to a substrate container capable of supporting multiple substrates in layers, and more particularly to a substrate container with adjustable stop components that can be easily and quickly adjusted to be used for supporting substrates of different lengths. In semiconductor or electronic circuit manufacturing processes, substrate containers are frequently used to transport multiple substrates (such as wafers or circuit boards) smoothly to different process workstations, thus preventing damage from collisions during transportation. A typical substrate container consists of a carrier box and a pair of support frames. The support frames are installed inside the carrier box to support the substrates in layers, and each support frame usually has stoppers at its end for positioning to prevent the substrates from swaying back and forth. However, when substrates are still in the R&D and testing phase before mass production, their dimensions are often slightly adjusted to accommodate process improvements or optimizations. Therefore, substrates of different lengths require corresponding support frames to ensure they don't wobble when placed. This necessitates the production of support frames of various sizes, significantly increasing production costs and inventory issues. Furthermore, disassembling and replacing these support frames is inconvenient and time-consuming. Therefore, designing a substrate container that can be easily and quickly adjusted to accommodate substrates of different lengths is a crucial improvement needed. In view of this, the author has devoted himself to researching and applying theoretical principles to address the shortcomings of the existing technology, and has made every effort to solve the aforementioned problems, which is the goal of the author's improvement. The main purpose of this disclosure is to enable convenient and quick adjustment of the adjustable stop assembly, so that the stop part with the required stop thickness can stop on the side of the side support frame, thereby enabling each side support frame to be used to support substrates of different lengths. To achieve the above objectives, this disclosure provides a substrate container with an adjustable stop assembly, comprising a housing, a pair of side support frames, and an adjustable stop assembly. The housing has a receiving groove, an open side, and a closed side, with the open side and closed side located on opposite sides of the receiving groove. Each side support frame is disposed on opposite sides of the receiving groove and located between the open side and the closed side. Each side support frame has a plurality of support plates, each support plate of which protrudes from one side support frame toward the other and is arranged parallel to each other. The adjustable stop assembly corresponds to one of the side support frames. The adjustable stop assembly, located on the closed side, includes a rotating rod and a positioning mechanism. The rotating rod has a centerline and a plurality of stop portions, each of which is radially arranged around the centerline. At least two of the stop portions have different stop thicknesses. The positioning mechanism can switch between a positioning position and an adjustment position. When the positioning mechanism is in the positioning position, it locks the rotating rod, and one of the stop portions stops on the side of the corresponding side support frame facing the closed side. When the positioning mechanism is in the adjustment position, it releases the rotating rod, allowing the rotating rod to rotate around the centerline. In one embodiment of the present disclosure, the positioning mechanism includes a lever pivotally mounted on a corresponding side support frame. The lever has a positioning insert and the rotating rod has a plurality of positioning slots. When the positioning mechanism is in the positioning position, the positioning insert can be selectively locked in one of the positioning slots to lock the position of the rotating rod. When the positioning mechanism is in the adjustment position, the positioning insert disengages from the positioning slot. In one embodiment disclosed herein, each positioning groove is configured to correspond to each stop portion. In one embodiment of this disclosure, the positioning mechanism further includes a torsion spring, and the side support frame corresponding to the adjustable stop assembly has a fixing block, with the two ends of the torsion spring fixed to the fixing block and the lever, respectively. In one embodiment of this disclosure, the side support frame corresponding to the adjustable stop assembly has a pair of pivot plates, and a rotating rod is pivotally connected to each pivot plate and located between the pivot plates. In one embodiment of the present disclosure, the positioning mechanism includes a compression spring, and the two ends of the rotating rod have a pivot and a plurality of positioning blocks, respectively. One pivot plate has a pivot hole, and the other pivot plate has a plurality of positioning holes. The pivot is pivotally connected to the pivot hole. The compression spring is sleeved on the pivot and elastically abuts against the end of the rotating rod corresponding to the pivot and the corresponding pivot plate. When the positioning mechanism is in the positioning position, each positioning block is accommodated in each positioning hole. When the positioning mechanism is in the adjustment position, each positioning block disengages from each positioning hole. In one embodiment disclosed herein, each positioning block is configured to correspond to each stop portion. In one embodiment of the present disclosure, each pivot plate has a pivot hole and a mounting channel, the mounting channel of each pivot plate is connected to the pivot hole, and each end of the rotating rod has a pivot shaft, each pivot shaft can slide through the mounting channel to be pivotally connected to the pivot hole. In one embodiment of this disclosure, each support plate has its two ends facing the open side and the closed side, respectively. In one embodiment of this disclosure, at least one stop is configured perpendicular to each support plate. In one embodiment of the present disclosure, each support plate has a pair of support protrusions, and each support protrusion of each support plate is disposed on both sides of the support plate corresponding to the open side and the closed side, respectively. In one embodiment of this disclosure, each support protrusion has a support guide slope on the side facing the opening. In one embodiment of the present disclosure, each support protrusion has a support guide slope on the side facing the opening and on the side facing the closing. In one embodiment of this disclosure, each stop is plate-shaped. In one embodiment of the present disclosure, at least one stop portion has a plurality of abutment blocks corresponding to each support plate, each abutment block extending protruding toward each support plate. In one embodiment of this disclosure, each abutment block has an abutment guide ramp formed on the side facing the positioning mechanism. In one embodiment of this disclosure, a bearing guide ramp is formed between each side bearing frame and its corresponding support plate. In one embodiment of the present disclosure, the housing has a pair of limiting grooves, each limiting groove extending from the open side toward the closed side, and each side support has a positioning protrusion, each positioning protrusion being accommodated in the limiting groove to limit the side support. In one embodiment of the present disclosure, the housing has a pair of limiting blocks, each limiting block extending from the closed side toward the open side, and each side support has a positioning protrusion, each positioning protrusion locking the limiting blocks to restrict each side support. In one embodiment disclosed herein, a plurality of bolts are also included, each side support having a pair of connecting portions, each bolt passing through the housing and screwing onto the connecting portions. The substrate container with adjustable stop assembly disclosed herein is configured on the closed side corresponding to one of the side support frames through the adjustable stop assembly. The rotating rod of the adjustable stop assembly has a plurality of stop portions arranged radially around the axis and having different stop thicknesses. The positioning mechanism can switch between a positioning position and an adjustment position to lock or release the rotating rod, thereby allowing one of the stop portions to stop on the side of the corresponding side support frame facing the closed side or allowing the rotating rod to rotate around the axis. Therefore, the adjustable stop assembly can be easily and quickly adjusted so that the stop portion with the required stop thickness can stop on the side of the side support frame, thereby allowing each side support frame to be used to support substrates of different lengths.

The detailed description and technical content of this disclosure will be explained in conjunction with the following drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this disclosure. This disclosure provides a substrate container with adjustable stop components for supporting a plurality of substrates A, such as wafers, glass substrates, or PCB circuit boards. Referring to Figures 1 to 3, the substrate container with adjustable stop components disclosed herein mainly includes a housing 10, a pair of side support frames 20, and at least one adjustable stop component 30. In this embodiment, the number of adjustable stop components 30 corresponds to the number of side support frames 20, which is two. However, this disclosure is not limited to this. For ease of description, only a single adjustable stop component 30 will be used for illustration, but it is not limited to the number of adjustable stop components 30 disclosed herein being only one. In this embodiment, the housing 10 is generally a hollow rectangle, but this disclosure is not limited thereto. The housing 10 has a receiving groove 11, an open side 12, and a closed side 13. Specifically, the open side 12 and the closed side 13 are located on opposite front and rear sides of the receiving groove 11, and the receiving groove 11 can be connected to the external space through the open side 12. Each side support frame 20 is respectively disposed on the left and right opposite sides within the receiving groove 11, and each side support frame 20 is located between the open side 12 and the closed side 13. More specifically, each side support frame 20 is parallel to each other, and each side support frame 20 is vertically arranged between the open side 12 and the closed side 13. Each side support frame 20 has a plurality of support plates 21 to support each of the substrates A. In each side support frame 20, each support plate 21 protrudes from the side support frame 20 toward the other side support frame 20 and is arranged parallel to each other. Specifically, each support plate 21 is elongated and its two ends face the open side 12 and the closed side 13 respectively, and the support plates 21 of each side support frame 20 are arranged sequentially and parallelly in the vertical direction. In this way, the opposite sides of each substrate A can be placed on the corresponding support plates 21 of each side support frame 20, so that each substrate A can be placed in layers between each side support frame 20. The adjustable stop assembly 30 is disposed on the closed side 13 corresponding to one of the side support frames 20. Specifically, in this embodiment, a pair of adjustable stop assemblies 30 are respectively disposed on the left and right sides of the closed side 13, corresponding to each side support frame 20. The adjustable stop assembly 30 includes a rotating rod 31 and a positioning mechanism 32. In this embodiment, each rotating rod 31 is rotatably pivoted on the corresponding side support frame 20. However, this disclosure is not limited to this. For example, each rotating rod 31 can also be rotatably pivoted inside the housing 10, as long as each rotating rod 31 is arranged on the closed side 13 corresponding to each side support frame 20. Each adjustable stop assembly 30 has a pair of pivot plates 22 on the side facing the closed side 13. Each rotating rod 31 is pivotally connected to the corresponding pivot plates 22 and located between the pivot plates 22. Specifically, each pivot plate 22 has a pivot hole 221, and each rotating rod 31 has a protruding pivot 311 at both ends. Each pivot 311 of each rotating rod 31 is pivotally connected in the pivot hole 221 of the corresponding pivot plate 22, thereby enabling it to pivot relative to the corresponding side support frame 20. Furthermore, each pivot plate 22 has a mounting groove 222, and the mounting groove 222 of each pivot plate 22 communicates with the pivot hole 221. Thus, each pivot 311 can slide through the mounting groove 222 to be pivotally connected to the pivot hole 221, thereby facilitating the installation of the rotating rod 31. The rotating rod 31 mainly includes a body 312, which has a centerline 313 and a plurality of stops 314. The aforementioned pivots 311 are respectively disposed at opposite ends of the body 312. Each stop 314 is radially arranged on the outer edge of the body 312 with the centerline 313 as the center. In this embodiment, there are two stops 314, but in other embodiments there may be three or more to accommodate the needs of substrates A of greater sizes; therefore, this disclosure does not impose further limitations on this. Each stop 314 is plate-shaped, and at least two of the stops 314 have different stop thicknesses t. In other words, the stop portions 314 can be designed with different stop thicknesses t to accommodate different length dimensions of the substrate A. To facilitate user operation, each positioning mechanism 32 in this embodiment is respectively located on the top of each side support frame 20. However, this disclosure is not limited to this. For example, each positioning mechanism 32 can also be installed inside the housing 10, as long as each positioning mechanism 32 is respectively configured on the closed side 13 corresponding to each side support frame 20. The positioning mechanism 32 can switch between a positioning position S1 and an adjustment position S2, that is, the user can switch the state of the positioning mechanism 32 according to needs. Specifically, as shown in Figures 3 to 5, when the positioning mechanism 32 is located in the positioning position S1, the positioning mechanism 32 locks the corresponding rotating rod 31 so that the rotating rod 31 cannot rotate, and one of the stop portions 314 on the rotating rod 31 stops on the side of the corresponding side support frame 20 facing the closed side 13, thereby stopping the substrate A so that the substrate A can no longer be pushed towards the closed side 13. Please refer to Figure 6. When the positioning mechanism 32 is in the adjustment position S2, the positioning mechanism 32 releases the corresponding rotating rod 31 so that the rotating rod 31 can rotate around the axis 313, so that the user can rotate the rotating rod 31 to the desired position. Further explanation, referring again to Figures 3 and 4, shows that each positioning mechanism 32 in this embodiment mainly includes a lever 321. The lever 321 is pivotally mounted on the corresponding side support frame 20, that is, in this embodiment, the lever 321 is pivotally mounted on the top of the corresponding side support frame 20. Thus, by pivoting the lever 321 on the side support frame 20, the user can move the lever 321 to adjust its position, thereby switching between the positioning position S1 and the adjustment position S2. Furthermore, each positioning mechanism 32 in this embodiment also includes a torsion spring 322. Each adjustable stop assembly 30 has a fixing block 23 on its side support frame 20. Specifically, each fixing block 23 is disposed on the top of the corresponding side support frame 20 and adjacent to the closed side 13. Each positioning mechanism 32 has its two ends of a torsion spring 322 fixed to a fixing block 23 and a lever 321, respectively. This allows the torsion spring 322 to apply a torque to the lever 321, causing it to rotate towards the positioning position S1. Therefore, when the user wants to adjust the lever 31, only a slightly greater external force than this torque is needed to rotate the lever 321 to the adjustment position S2. After adjusting the lever 31 to the desired position, the torsion spring 322's own elasticity will return the lever 321 to the positioning position S1. In this embodiment, the fixing blocks 23 of each side support frame 20 are T-shaped protrusions arranged back-to-back, such that one end of the torsion spring 322 is engaged between the T-shaped protrusions of the fixing block 23. However, the shape of the fixing block 23 disclosed herein is not limited to this. Furthermore, to prevent the rotating rod 31 of the positioning mechanism 32 from rotating due to external force, vibration, impact, or shaking when the positioning mechanism 32 is in the positioning position S1, the lever 321 in this embodiment has a positioning insert 3211, and the rotating rod 31 has a plurality of positioning slots 315. The positioning insert 3211 can be selectively locked in one of the positioning slots 315 to lock the position of the rotating rod 31, thereby preventing the rotating rod 31 from rotating when the positioning mechanism 32 is in the positioning position S1. Specifically, each positioning slot 315 is respectively disposed on the pivot plate 22 of the corresponding positioning mechanism 32 corresponding to each stop 314, so the positioning insert 3211 can be locked in the positioning slot 315 corresponding to any stop 314. In other words, when the positioning mechanism 32 is in the positioning position S1, the positioning insert 3211 can be selectively locked in one of the positioning slots 315, so that the stop 314 to be used can be locked in the position of the rotating rod 31 by the positioning insert 3211 after being rotated to the desired position. When the positioning mechanism 32 is in the adjustment position S2, the positioning insert 3211 will disengage from each positioning slot 315, so that the user can rotate the rotating rod 31 to adjust the position of each stop 314. Please refer to Figures 9 to 11, which show another embodiment of this disclosure. The main difference is that the positioning mechanism 32 includes a compression spring 323, which will be described in detail below. In this embodiment, the compression spring 323 of the positioning mechanism 32 is disposed at the top of the rotating rod 31, but this disclosure is not limited to this, as long as it is disposed at one end of the rotating rod 31. The body 312 of the rotating rod 31 has a plurality of positioning blocks 316 at the end away from the compression spring 323, and each positioning block 316 is respectively configured corresponding to each stop portion 314. The side support frame 20 has a plurality of positioning holes 223 corresponding to each positioning block 316 on the pivot plate 22 away from the compression spring 323. In this embodiment, each pivot 311 of the rotating rod 31 is still pivotally connected to each pivot hole 221 of each pivot plate 22, thereby being able to rotate relative to the side support frame 20. The compression spring 323 of the positioning mechanism 32 is sleeved on the pivot 311 at the top of the rotating rod 31, and the two ends of the compression spring 323 elastically abut against the top of the body 312 of the rotating rod 31 and the corresponding pivot plate 22, respectively. Thus, the compression spring 323 can exert a spring force on the rotating rod 31 toward the bottom of the receiving groove 11 through its own elastic force. Therefore, as shown in FIG10, when the positioning mechanism 32 is in the positioning position S1, the spring force exerted by the compression spring 323 on the rotating rod 31 causes each positioning block 316 to be respectively accommodated in each positioning hole 223, thereby fixing the rotating rod 31 to the side support frame 20 and preventing it from rotating. Please refer to Figure 11. When the user wants to adjust the rotating rod 31, he only needs to apply an external force slightly greater than the elastic force to move the rotating rod 31 upward so that the positioning mechanism 32 is in 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 will disengage from each positioning hole 223 of the side support frame 20, so that the user can rotate the rotating rod 31 to adjust the required stop 314 to the required position. Referring again to Figures 3 and 5, in each rotating rod 31, at least one stop 314 is configured perpendicular to each support plate 21 of the corresponding side support frame 20, thereby stopping the corresponding side support frame 20 on the side facing the closed side 13. Furthermore, as shown in Figure 3, at least one stop 314 has a plurality of abutment blocks 3141 corresponding to each support plate 21, thereby increasing the stopping thickness t of the stop 314. Specifically, each abutment block 3141 extends protruding towards each support plate 21 to increase the stopping thickness t, but this disclosure is not limited thereto. Each abutment block 3141 has an abutment guide slope 3142 formed on the side facing the positioning mechanism 32, thereby providing guidance during the placement of each of the substrates A and preventing jamming or scratching. Also, each support plate 21 has a pair of support protrusions 211. Each support plate 21 has support protrusions 211 respectively disposed on the front and rear sides of the support plate 21 corresponding to the open side 12 and the closed side 13. Each support protrusion 211 has a support guide slope 2111 formed on the side facing the open side 12, thereby providing guidance when each substrate A is pushed into the side support frame 20 to prevent jamming or scratching. In this embodiment, each support protrusion 211 has support guide slopes 2111 formed on both the side facing the open side 12 and the side facing the closed side 13, so that each substrate A can be guided when pushed into or out of the side support frame 20 to prevent jamming or scratching. In addition, a support guide slope 24 is formed between each side support frame 20 and the corresponding support plate 21. Specifically, each bearing guide ramp 24 faces the top of the corresponding side support frame 20, so that when each of the substrates A is placed on the corresponding support plate 21, it can form a guide and is not easy to get stuck or scratched, and thus be placed stably on the corresponding support plate 21. Further explanation is provided in Figures 1, 2, and 12. The housing 10 has a pair of limiting grooves 14 and a pair of limiting blocks 15. Each limiting groove 14 is approximately located on the left and right sides of the receiving groove 11 and extends from the open side 12 toward the closed side 13. Each side support frame 20 has a positioning protrusion 25. Specifically, each positioning protrusion 25 is located at the top of the corresponding side support frame 20 and adjacent to the open side 12 of the housing 10. Thus, each positioning protrusion 25 of each side support frame 20 can be accommodated within its respective limiting groove 14, thereby preventing the side support frame 20 from swaying left and right. Each limiting block 15 is also approximately located on the left and right sides of the receiving groove 11 and extends from the closed side 13 toward the open side 12. Each side support frame 20 has a positioning protrusion 26. Specifically, each positioning protrusion 26 is located at the top of the corresponding side support frame 20 and adjacent to the closed side 13 of the housing 10. Therefore, each positioning protrusion 26 of each side support frame 20 can respectively engage each limiting block 15 of the housing 10, thereby preventing each side support frame 20 from swaying left and right and preventing each side support frame 20 from being pushed further into the closed side 13. Furthermore, the substrate container with adjustable stop assembly disclosed herein also includes a plurality of bolts 40. Each side support frame 20 has a pair of connecting portions 27 at its bottom. In this embodiment, each connecting portion 27 of each side support frame 20 is disposed adjacent to the open side 12 and the closed side 13, but this disclosure is not limited thereto. Each bolt 40 passes through the bottom of the housing 10 and is screwed into a screw hole (not shown) in each connecting portion 27, thereby fixing each side support frame 20 inside the housing 10. The substrate container with adjustable stop assembly disclosed herein is configured on the closed side 13 via an adjustable stop assembly 30 corresponding to one of the side support frames 20. The rotating rod 31 of the adjustable stop assembly 30 has a plurality of stop portions 314 arranged radially around the axis 313 and having different stop thicknesses t. The positioning mechanism 32 can switch between a positioning position S1 and an adjustment position S2 to lock or release the rotating rod 31, thereby allowing one of the stop portions 314 to stop on the side of the corresponding side support frame 20 facing the closed side 13 or allowing the rotating rod 31 to rotate around the axis 313. Therefore, the adjustable stop assembly 30 can be adjusted conveniently and quickly, so that the stop portion 314 with the required stop thickness t can stop on the side of the side support frame 20, thereby allowing each side support frame 20 to be used to support substrates A of different lengths. In summary, the foregoing disclosure is intended to enable those skilled in the art to clearly understand the technical content of this disclosure and implement it accordingly, and is not intended to limit the scope of patent protection of this disclosure. In addition, this disclosure may of course have other embodiments not listed. Without departing from the spirit and essence of this disclosure, those skilled in the art should be able to devise various corresponding changes and modifications based on this disclosure, but all such changes and modifications should fall within the scope of protection of the patents claimed under this disclosure. 10: Box body 11: Container groove 12: Open side 13: Closed side 14: Limiting groove 15: Limiting block 20: Side support frame 21: Support plate 211: Supporting protrusion 2111: Supporting guide slope 22: Pivot plate 221: Pivot hole 222: Mounting groove 223: Positioning hole 23: Fixing block 24: Bearing guide slope 25: Positioning protrusion 26: Positioning protrusion 27: Connecting part 30: Adjustable stop assembly 31: Rotating rod 311: Pivot 312: Body 313: Axis line 314: Stop part 3141: Abutting block 3142: Abutting guide slope 315: Positioning groove 316: Positioning block 32: Positioning mechanism 321: Lever 3211: Positioning insert 322: Torsion spring 323: Compression spring 40: Bolt A: Base material t: Stop thickness S1: Positioning position S2: Adjustment position Figure 1 is a three-dimensional view of the exterior of the present invention.
