Description

Technical Field

[0001] This utility model relates to the field of RFID reading and writing technology for crystal boat boxes, specifically to an RFID reading and writing tooling for crystal boat boxes. Background Technology

[0002] The wafer carrier box is a core container used in the semiconductor manufacturing industry to carry, protect, and transport wafers. Its material must meet the high cleanliness requirements of semiconductor manufacturing, with mainstream types including quartz, silicon carbide, and engineering plastics. As semiconductor manufacturing moves towards high-precision, large-size wafers, such as 8-inch and 12-inch wafers, and multi-process collaboration, wafer lifecycle traceability has become a key link in ensuring product quality and reducing defect rates. The wafer carrier box RFID reading and writing tooling, as a core device for full-process traceability in semiconductor manufacturing, is specifically designed for automated information management of wafer carrier containers. It can completely solve industry pain points such as batch confusion and traceability gaps caused by manual recording, and is an important support for realizing intelligent control of semiconductor production lines.

[0003] However, the RFID reading and writing fixtures currently available on the market still have the following problems in practical applications: most of the existing reading and writing fixtures are designed with fixed dimensions. When changing to fixtures that are compatible with different crystal boxes, a large number of bolts and other fasteners need to be disassembled. Each disassembly and assembly takes a long time, which greatly increases the difficulty of operation and makes them less practical. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a crystal boat box RFID reading and writing fixture to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crystal boat RFID reading and writing fixture, including a reading and writing platform, an alignment seat, and a crystal boat box that is inserted and installed with the alignment seat. The top of the reading and writing platform is provided with clamping assemblies on both sides of the alignment seat. A snap-fit ​​strip is fixedly installed on the back of the top of the reading and writing platform. A snap-fit ​​hole adapted to the snap-fit ​​strip is opened on the back of the alignment seat. An alignment insertion strip is fixedly installed on the inner side of the alignment seat. Alignment insertion slots adapted to the alignment insertion strip are opened on both sides of the lower part of the crystal boat box. A scanning component and a reading and writing component are also provided on the top of the reading and writing platform.

[0006] Preferably, the clamping assembly includes a support base and a guide base. An outer connector is rotatably mounted on the inner side of the support base away from the guide base. A pull rod is fixedly mounted on the outer connector away from the support base. An inner connector is rotatably mounted on the inner side of the outer connector. A push rod is rotatably mounted on the inner connector away from the outer connector. A push block is fixedly mounted on the push rod away from the inner connector. A pressure plate is fixedly mounted on the outer side of the push block. The push rod and the guide base are slidably connected.

[0007] With the above technical solution, pulling the lever in the clamping assembly will cause the outer connector to rotate around the inner side of the support seat away from the guide seat, thereby driving the inner connector to rotate synchronously. During the rotation of the inner connector, the push rod will slide in the guide seat, causing the push block at the end of the push rod away from the inner connector to move towards the alignment seat. Finally, the pressure plate on the outside of the push block will abut against the outer wall of the alignment seat, realizing the clamping operation of the alignment seat. The design of the clamping assembly makes it convenient to clamp alignment seats of different sizes, and also makes it convenient to replace the alignment seat.

[0008] Preferably, there are four identical clamping assemblies, which are symmetrically distributed in pairs on both sides of the positioning seat. The push block and the pressure plate together form an inverted "L" shaped structure, and both the push block and the pressure plate are in contact with the positioning seat.

[0009] With the above technical solution, the four clamping components are symmetrically distributed in pairs on both sides of the alignment seat, which can apply clamping force evenly from the left and right sides of the alignment seat to prevent the alignment seat from tilting due to uneven force on one side. At the same time, the inverted "L" shaped structure formed by the push block and the pressure plate can fit the side and top of the alignment seat, which can achieve a good clamping effect.

[0010] Preferably, the number of the alignment strips and the alignment slots are the same and correspond one-to-one, and the cross-sections of the alignment strips and the alignment slots are all "D" shaped.

[0011] Through the above technical solution, the number of alignment strips and alignment slots corresponds one-to-one, which can guide the crystal boat box to be accurately inserted into the alignment seat, avoid misalignment during crystal boat box installation, and play the role of alignment installation.

[0012] Preferably, a mounting groove is provided on the rear side of the top of the reading and writing station, and a snap-fit ​​groove is provided inside the mounting groove at the top of the reading and writing station. A snap-fit ​​seat adapted to the snap-fit ​​groove is fixedly installed on the side of the scanning component facing the reading and writing station. The scanning component and the reading and writing station are detachably connected by locking bolts.

[0013] Through the above technical solution, the design of the snap-fit ​​groove and snap-fit ​​base allows for proper alignment during installation. Inserting the snap-fit ​​base into the snap-fit ​​groove facilitates subsequent alignment and tightening of the locking bolts.

[0014] Preferably, the card holder and the card slot are connected by a plug-in connection, and the mounting slot is connected by a plug-in connection to the lower part of the barcode scanning component.

[0015] The above technical solution allows for quick positioning simply by plugging in the components, improving the installation efficiency of the barcode scanning components and ensuring that the barcode scanning components can be accurately aligned with the marking area of ​​the crystal box.

[0016] Preferably, the snap-fit ​​holes of the snap-fit ​​strip are plug-in connections, and all snap-fit ​​holes of the snap-fit ​​strip are located on the axis of the positioning seat.

[0017] Through the above technical solution, the insertion connection between the connector strip and the connector hole can quickly realize the assembly of the alignment base and the reader / writer station without the need for complicated tools, which improves the assembly and disassembly efficiency of the alignment base. Moreover, since both the connector strip and the connector hole are located on the axis of the alignment base, it can ensure that the alignment base is always in the center position of the reader / writer station when it is installed on the reader / writer station. This avoids the alignment base from shifting and causing the crystal boat box to deviate from the effective range of the reader / writer component, ensuring that the reader / writer component can stably read the RFID information of the crystal boat box. At the same time, it is also convenient to replace the alignment base with different sizes to adapt to crystal boat boxes of different sizes.

[0018] Compared with the prior art, this utility model provides a crystal boat box RFID reading and writing fixture, which has the following beneficial effects: 1. This RFID reading and writing fixture for crystal boat boxes features four symmetrically distributed inverted "L"-shaped clamping structures that securely hold different sized alignment seats. Combined with the snap-fit ​​strips and snap-fit ​​holes arranged along the alignment seat axis, this design allows for quick assembly and disassembly of the alignment seat and the reading / writing station without the need for complex tools, significantly reducing assembly and replacement time. It facilitates the replacement of alignment seats of different sizes to fit various crystal boat boxes and ensures that the alignment seat remains centered on the reading / writing station, preventing the crystal boat box from deviating from the effective range of the reading / writing components and guaranteeing the stability of RFID information reading.

[0019] 2. This RFID reading and writing fixture for the crystal boat box uses a one-to-one matching "D"-shaped alignment strip and alignment slot to guide precise insertion into the alignment seat, avoiding misalignment. For the barcode scanning component, the installation slot, snap-fit ​​slot, and snap-fit ​​seat can be quickly positioned by interlocking. The subsequent detachable connection can be achieved by tightening the bolts. This not only improves the installation efficiency of the barcode scanning component but also ensures that it can be accurately aligned with the marking area of ​​the crystal boat box. At the same time, the precise alignment of the crystal boat box further ensures the overall reliability of the fixture's operation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: like Figure 1-9 As shown, the present invention provides a crystal boat box RFID reading and writing fixture, including a reading and writing platform 1, an alignment seat 2, and a crystal boat box 4 that is inserted and installed with the alignment seat 2. The top of the reading and writing platform 1 is provided with clamping assemblies 3 on both sides of the alignment seat 2. A snap-fit ​​strip 9 is fixedly installed on the back of the top of the reading and writing platform 1. The back of the alignment seat 2 is provided with snap-fit ​​holes 10 that are adapted to the snap-fit ​​strip 9. An alignment insertion strip 7 is fixedly installed on the inner side of the alignment seat 2. Alignment insertion slots 8 that are adapted to the alignment insertion strip 7 are provided on both sides of the lower part of the crystal boat box 4. The top of the reading and writing platform 1 is also provided with a scanning assembly 5 and a reading and writing assembly 6.

[0024] Example 2: like Figure 2-9 As shown, as an improvement to the previous embodiment, the alignment seat 2 of different sizes is replaced to facilitate replacement.

[0025] Specifically, the clamping assembly 3 includes a support base 301 and a guide base 302. An outer connector 303 is rotatably mounted on the inner side of the end of the support base 301 away from the guide base 302. A pull rod 304 is fixedly mounted on the end of the outer connector 303 away from the support base 301. An inner connector 305 is rotatably mounted on the inner side of the outer connector 303. A push rod 306 is rotatably mounted on the end of the inner connector 305 away from the outer connector 303. A push block 307 is fixedly mounted on the end of the push rod 306 away from the inner connector 305. A pressure plate 308 is fixedly mounted on the outer side of the push block 307. The push rod 306 and the guide base 302 are slidably connected. The advantage is that when the pull rod 304 in the clamping assembly 3 is pulled, the outer connector 303 will rotate around the inner side of the support seat 301 away from the guide seat 302, thereby driving the inner connector 305 to rotate synchronously. During the rotation of the inner connector 305, the push rod 306 will slide in the guide seat 302, causing the push block 307 at the end of the push rod 306 away from the inner connector 305 to move towards the alignment seat 2. Finally, the pressure plate 308 on the outer side of the push block 307 will abut against the outer wall of the alignment seat 2, realizing the clamping operation of the alignment seat 2. Through the design of the clamping assembly 3, it is convenient to clamp alignment seats 2 of different sizes, and it is also convenient to replace the alignment seat 2.

[0026] Specifically, four identical clamping assemblies 3 are provided, symmetrically distributed in pairs on both sides of the alignment seat 2. The push block 307 and the pressure plate 308 together form an inverted "L" shape structure, with both the push block 307 and the pressure plate 308 in contact with the alignment seat 2. The advantage is that the symmetrical distribution of the four clamping assemblies 3 in pairs on both sides of the alignment seat 2 allows for even application of clamping force from both sides, preventing the alignment seat 2 from tilting due to uneven force on one side. Simultaneously, the inverted "L" shape structure formed by the push block 307 and the pressure plate 308 conforms to the sides and top of the alignment seat 2, achieving a good clamping effect.

[0027] Example 3: like Figure 2-9 As shown, as an improvement to the previous embodiment, in order to guide the crystal boat box 4 to be accurately inserted into the alignment seat 2.

[0028] Specifically, the number of alignment strips 7 and alignment slots 8 are the same and correspond one-to-one. The cross-section of both alignment strips 7 and alignment slots 8 is a "D" shape. The advantage is that the one-to-one correspondence between the number of alignment strips 7 and alignment slots 8 can guide the crystal boat box 4 to be accurately inserted into the alignment seat 2, avoiding misalignment during the installation of the crystal boat box 4, and thus achieving the function of alignment installation.

[0029] Example 4: like Figure 2-9 As shown, as an improvement to the previous embodiment, in order to achieve quick assembly and disassembly of the barcode scanning component 5.

[0030] Specifically, a mounting groove 11 is provided on the rear side of the top of the reader / writer 1. A snap-fit ​​groove 12 is provided inside the mounting groove 11 at the top of the reader / writer 1. A snap-fit ​​bracket 13, adapted to the snap-fit ​​groove 12, is fixedly installed on the side of the barcode scanning component 5 facing the reader / writer 1. The barcode scanning component 5 and the reader / writer 1 are detachably connected by a locking bolt 14. The advantage is that, through the design of the snap-fit ​​groove 12 and the snap-fit ​​bracket 13, during installation, inserting the snap-fit ​​bracket 13 into the snap-fit ​​groove 12 ensures proper alignment, facilitating subsequent alignment and tightening of the locking bolt 14.

[0031] Specifically, the card holder 13 and the card slot 12 are connected by a plug-in connection, and the mounting slot 11 is connected to the lower part of the barcode scanning component 5 by a plug-in connection. The advantage is that positioning can be quickly completed by plugging in, which improves the installation efficiency of the barcode scanning component 5 and ensures that the barcode scanning component 5 can be accurately aligned with the marking area of ​​the crystal boat box 4.

[0032] Example 5: like Figure 2-9 As shown, as an improvement to the previous embodiment, the alignment seat 2 of different sizes is replaced to facilitate replacement.

[0033] Specifically, the snap-fit ​​holes 10 of the snap-fit ​​strip 9 are plug-in connections, and all snap-fit ​​holes 10 of the snap-fit ​​strip 9 are located on the axis of the alignment base 2. The advantage is that the plug-in connection between the snap-fit ​​strip 9 and the snap-fit ​​holes 10 allows for quick assembly of the alignment base 2 and the reader / writer station 1 without the need for complex tools, improving the efficiency of assembly and disassembly of the alignment base 2. Furthermore, since both the snap-fit ​​strip 9 and the snap-fit ​​holes 10 are located on the axis of the alignment base 2, it ensures that the alignment base 2 is always centered on the reader / writer station 1 when installed, preventing the alignment base 2 from shifting and causing the crystal boat box 4 to deviate from the effective range of the reader / writer assembly 6. This ensures that the reader / writer assembly 6 can stably read the RFID information of the crystal boat box 4, and also facilitates the replacement of alignment bases 2 of different sizes to adapt to crystal boat boxes 4 of different sizes.

[0034] Working principle: In use, first select the appropriate alignment seat 2 according to the size of the crystal boat box 4 to be processed. Align the snap-fit ​​hole 10 on the back of the alignment seat 2 with the snap-fit ​​strip 9 on the back of the top of the reader / writer table 1 to complete the initial positioning. Then operate the clamping assemblies 3 on both sides of the alignment seat 2, pull the pull rod 304 to make the outer connecting piece 303 rotate around the support base 301, thereby driving the inner connecting piece 305 to push the push rod 306 to slide in the guide seat 302, so that the inverted "L" shaped pressure plate 308 on the outside of the push block 307 abuts against the side and top of the alignment seat 2 to achieve a stable clamping, thus completing the installation of the alignment seat 2. Next, assemble the barcode scanning assembly 5, align its lower part with the mounting groove 11 on the rear side of the top of the reader / writer table 1 and insert it, while making the bottom snap-fit ​​seat 13 snap into the mounting groove 11. The slot 12 is inserted and positioned, and then it can be detached and fixed by the locking bolt 14. At this time, the reading and writing component 6 is in the preset working position. Then, the crystal boat box 4 is read and written. The alignment slots 8 on both sides of the lower part of the crystal boat box 4 are aligned with the corresponding "D"-shaped alignment strips 7 on the inner side of the alignment seat 2 and inserted smoothly until they fit completely to achieve accurate positioning. Then, the tooling working program is started. The barcode scanning component 5 first scans the marking area of ​​the crystal boat box 4 to collect basic information, and then the reading and writing component 6 reads or writes information on the RFID tag on the crystal boat box 4. If it is necessary to replace the crystal boat box 4 of a different size, the clamping component 3 is operated in reverse to loosen the pressure plate 308, the old alignment seat 2 is removed and replaced with the new matching alignment seat 2. The above installation and insertion steps are repeated to quickly switch the work.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
