Description

Technical Field

[0001] This utility model relates to the field of readers, specifically a high-frequency reader that is easy to install and maintain. Background Technology

[0002] The SRE-D06 is a high-performance UHF RFID reader that integrates an antenna and a reader / writer. It is designed based on the high-performance IMPINJ E710 / E510 / E310 reader / writer chip and fully supports electronic tags that comply with the EPCglobal C1 Gen 2 ISO 18000-6C standard. It can be widely used in reading applications in logistics production lines, industrial assembly lines, and manufacturing workshop workstations.

[0003] Existing easy-to-install and maintain high-frequency readers generally require double-layer, multi-screw locking for installation and fixation. The first layer involves connecting the all-in-one device to the bracket, which requires securing it with multiple screws one by one. The second layer involves connecting the bracket to the pole, which also requires tightening multiple screws one by one. During disassembly and assembly, workers need to switch between various tools (such as different types of screwdrivers and wrenches) for different screw locations, and each screw needs to be tightened individually, without a unified quick tightening / unlocking mechanism. If the all-in-one device malfunctions and requires maintenance (such as decreased reading accuracy), all connecting screws between the bracket and the pole must be removed first, and the bracket and all-in-one device must be removed from the pole as a whole before the screws between the all-in-one device and the bracket can be removed. It is difficult to quickly separate the all-in-one device. In industrial scenarios (such as logistics production lines and workshop workstations), this process leads to a significant increase in ineffective maintenance steps, making rapid repair impossible and reducing the efficiency of disassembly and maintenance of the all-in-one device. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a high-frequency reader / writer that is easy to install and maintain, so as to solve the technical problem of low disassembly and assembly efficiency of the reader / writer, which affects its maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install and maintain high-frequency reader / writer, comprising an ultra-high frequency RFID integrated machine and a pole. Four positioning rods are installed on the back of the ultra-high frequency RFID integrated machine, and a bracket is fitted onto the outer wall of each positioning rod. Locking holes are provided on the positioning rods. A threaded post is fixed to the back of the bracket, and a second nut and a slide are respectively fitted onto the outer wall of the threaded post. Limiting grooves are provided on both sides of the back of the bracket, and limiting seats are provided inside the limiting grooves. A rotating plate is rotatably connected to the limiting seat and the slide via a pin. A locking post extending into the locking hole is installed on one side of the limiting seat.

[0006] By adopting the above technical solution, the UHF RFID all-in-one machine integrates an antenna and a reader / writer. The UHF RFID all-in-one machine is based on the IMPINJ E710 / E510 / E310 chip and can read electronic tags that conform to the EPCglobal C1 Gen 2 / ISO 18000-6C standard.

[0007] Furthermore, the outer wall of the upright is fitted with two U-shaped screws and fastening teeth, and the fastening teeth have two second through holes.

[0008] By adopting the above technical solution, the pole supports the entire reader device and is suitable for column installation in outdoor / industrial scenarios (such as logistics production lines and workshop workstations).

[0009] Furthermore, the bracket has four first through holes, and the screw section of the U-shaped screw passes through the first and second through holes.

[0010] By adopting the above technical solution, the fastening teeth fit against the outer wall of the upright, increasing the contact area with the upright; and in conjunction with the U-shaped screw, the upright is clamped to prevent the support from sliding on the upright.

[0011] Furthermore, the screw section of the U-shaped screw is fitted with a flat washer, a spring washer, and a first nut from left to right. The flat washer is in contact with the bracket, and the spring washer is in contact with both the flat washer and the first nut.

[0012] By adopting the above technical solutions, the flat washer disperses the pressure, and the spring washer prevents loosening (counteracting the loosening of the first nut caused by vibration), thus solving the problem of easy loosening of the fixed structure during long-term use.

[0013] Furthermore, the UHF RFID all-in-one machine has an interface installed at its bottom, and the model of the UHF RFID all-in-one machine is SRE-D06.

[0014] By adopting the above technical solution, the interface is used for signal / power connection between the all-in-one machine and external devices (such as computers and controllers), ensuring data transmission and device power supply; the SRE-D06 has a built-in Linux operating system, which can embed application business logic, and middleware is built into the reader's Linux system for edge computing to reduce the complexity of architecture and maintenance.

[0015] Furthermore, the locking pin is adapted to the locking hole, and the locking pin is slidably connected to the limiting groove through the limiting seat.

[0016] By adopting the above technical solution, the locking structure's fit ensures that the locking pin can be accurately inserted into the locking hole, and the limiting seat can drive the locking pin to move when it slides inside the limiting groove.

[0017] Furthermore, the bracket is an L-shaped bracket, and the bracket is fitted with the fastening teeth.

[0018] By adopting the above technical solution, the L-shaped bracket can serve the dual functions of supporting the integrated machine and connecting the uprights, and the close fit and fastening of the teeth can further improve the structural stability.

[0019] Furthermore, the outer wall of the locking pin is provided with an anti-slip ring made of silicone rubber material, and the outer wall of the anti-slip ring fits against the inner wall of the locking hole.

[0020] By adopting the above technical solution, the silicone rubber anti-slip ring increases the friction between the locking pin and the locking hole, solving the problem of the locking structure loosening due to vibration after the installation of the all-in-one machine.

[0021] Furthermore, the slide block is slidably connected to the threaded column, and both the threaded column and the U-shaped screw are made of stainless steel.

[0022] By adopting the above technical solutions, the stainless steel material improves corrosion resistance (suitable for outdoor / industrial environments), and the sliding connection between the slide and the threaded column ensures smooth adjustment of the slide and guarantees assembly and disassembly efficiency.

[0023] Furthermore, an elastic sleeve is installed between the slide and the bracket, and the elastic sleeve is made of polyurethane material.

[0024] By adopting the above technical solution, the polyurethane elastic sleeve provides cushioning (avoiding hard collisions) during slide adjustment and can assist in slide reset, further optimizing maintenance convenience.

[0025] In summary, the present invention has the following main advantages: 1. This utility model, by comprising a positioning rod, a limiting groove, a limiting seat, a threaded column, a locking hole, a locking column, a second nut, a slide block, an elastic sleeve, and a rotating plate, allows for easy disassembly of the UHF RFID integrated machine. When disassembly is required, the operator can rotate the second nut, causing it to move towards the upright. This causes the elastic sleeve to return to its original position, pushing the slide block back to its original position. The slide block then pulls the rotating plate, causing the limiting seat to slide within the limiting groove. The limiting seat then moves the locking column, causing it to move out of the locking hole. This releases the locking limit on the positioning rod, allowing the UHF RFID integrated machine to be pulled, separating the positioning rod from the bracket. This allows the UHF RFID integrated machine to be removed for maintenance. Furthermore, this disassembly method eliminates the need to loosen multiple bolts sequentially; simply rotating the second nut simplifies the disassembly process and improves the efficiency of disassembly and assembly of the UHF RFID integrated machine. The positioning rod, locking column, slide block, and other components contribute to this improved disassembly efficiency. The "rotating plate" linkage structure allows the disassembly and assembly machine to be installed and disassembled without disassembling the bracket. Locking / disassembly can be completed simply by adjusting the second nut, simplifying the steps (can be operated by a single person) and shortening maintenance time. 2. This utility model solves the problem of loosening of the locking structure due to vibration after installation by setting an anti-slip ring. The silicone rubber anti-slip ring increases the friction between the locking pin and the locking hole. The polyurethane elastic sleeve provides cushioning (avoiding hard collisions) when the slide is adjusted and can also assist the slide in resetting, further optimizing the convenience of maintenance.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1: An easy-to-install and maintain high-frequency reader, such as Figures 1-9 As shown, the device includes an UHF RFID integrated unit 1 and a pole 22. The UHF RFID integrated unit 1 integrates an antenna and a reader / writer, and is based on the IMPINJ E710 / E510 / E310 chip, with reading conforming to EPCglobal C1 Gen 2 / ISO standards. The 18000-6C standard electronic tag, UHF RFID integrated machine 1, has four positioning rods 3 installed on its back, and the outer wall of the positioning rods 3 is fitted with a bracket 10. The positioning rods 3 have locking holes 15. The back of the bracket 10 is fixed with a threaded post 14. The outer wall of the threaded post 14 is fitted with a second nut 17 and a slide 18. The second nut 17 fits into the slide 18. The second nut 17 is a nylon insert nut. Limiting grooves 12 are opened on both sides of the back of the bracket 10, and limiting seats 13 are set inside the limiting grooves 12. The limiting seats 13 and the slide 18 are rotatably connected by a rotating plate 20 through a pin. A locking post 16 extending into the locking hole 15 is installed on one side of the limiting seat 13.

[0031] See Figures 1-8 The locking pin 16 is adapted to the locking hole 15. The locking pin 16 is slidably connected to the limiting seat 13 and the limiting groove 12. The matching relationship of the locking structure ensures that the locking pin 16 can be accurately inserted into the locking hole 15. When the limiting seat 13 slides in the limiting groove 12, it can drive the locking pin 16 to move. The limiting seat 13 is convex. The bracket 10 is an L-shaped bracket. The bracket 10 fits with the fastening tooth 4. The L-shaped bracket 10 has the dual function of supporting the integrated machine and connecting the upright 22. Fitting with the fastening tooth 4 further improves the structural stability. The slide block 18 is slidably connected to the threaded post 14. Both the threaded post 14 and the U-shaped screw 11 are made of stainless steel. The stainless steel material improves corrosion resistance (suitable for outdoor / industrial environments). The sliding connection between the slide block 18 and the threaded post 14 ensures that the slide block 18 can be smoothly adjusted, ensuring efficient disassembly and assembly. An elastic sleeve 19 is installed between the slide block 18 and the bracket 10. The elastic sleeve 19 is made of polyurethane material. The polyurethane elastic sleeve 19 provides cushioning (avoiding hard collisions) when the slide block 18 is adjusted, and can also assist the slide block 18 in resetting, further optimizing the convenience of maintenance.

[0032] See Figures 1-9 The outer wall of the upright 22 is fitted with two U-shaped screws 11 and fastening teeth 4 respectively. The fastening teeth 4 has two second through holes 6. The upright 22 supports the entire reader device and is suitable for column installation in outdoor / industrial scenarios (such as logistics production lines and workshop workstations). The bracket 10 has four first through holes 5. The screw section of the U-shaped screw 11 passes through the first through holes 5 and the second through holes 6. The fastening teeth 4 fits against the outer wall of the upright 22 to increase the contact area with the upright 22; it cooperates with the U-shaped screws 11 to clamp the upright 22 and prevent the bracket 10 from sliding on the upright 22.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The bottom of the UHF RFID all-in-one machine 1 is equipped with interface 2. The model of the UHF RFID all-in-one machine 1 is SRE-D06. Interface 2 is used for signal / power connection between the all-in-one machine and external devices (such as computers and controllers) to ensure data transmission and power supply to the device. The SRE-D06 has a built-in Linux operating system, which can be built into the application's business logic. The middleware built into the reader's Linux system is used for edge computing to reduce the complexity of architecture and maintenance.

[0034] Example 2: Based on the above embodiment 1, the following structure will be set to improve the stability of the support 10.

[0035] Specifically, the screw section of the U-shaped screw 11 is fitted with a flat washer 7, a spring washer 8 and a first nut 9 from left to right. The flat washer 7 fits into the bracket 10, and the spring washer 8 fits into both the flat washer 7 and the first nut 9. The flat washer 7 disperses pressure, and the spring washer 8 prevents loosening (counteracts the loosening of the first nut caused by vibration), thus solving the problem of easy loosening of the fixed structure during long-term use.

[0036] Example 3: Based on the above embodiment 1, in order to improve the stability of the locking pin 16 being inserted into the locking hole 15, the following structure will be provided.

[0037] Specifically, the outer wall of the locking post 16 is provided with an anti-slip ring 21 made of silicone rubber. The outer wall of the anti-slip ring 21 fits against the inner wall of the locking hole 15. The silicone rubber anti-slip ring 21 increases the friction between the locking post 16 and the locking hole 15, solving the problem of the locking structure becoming loose due to vibration after the all-in-one machine is installed.

[0038] The working principle of this utility model is as follows: First, the workers put two U-shaped screws 11 and two fastening teeth 4 on the target height position of the upright 22, so that the U-shaped screws 11 and fastening teeth 4 fit against the outer wall of the upright 22. Then, one side of the L-shaped bracket 10 is aligned with the U-shaped screw, so that the screw section of the U-shaped screw 11 passes through the first through hole 5 of the bracket and the second through hole 6 of the fastening teeth 4 in sequence. From left to right, the flat washer 7 (fitting against the bracket 10) and the spring washer (8) (fitting against the flat washer 7) are put on the screw section of the U-shaped screw 11. Finally, the first nut 9 is tightened. When the first nut 9 is tightened, the pressure is distributed by the flat washer 7, and the spring washer 8 produces elastic deformation (anti-loosening), which drives the fastening teeth 4 and the U-shaped screw 11 to clamp the upright 22, thus completing the fixation of the bracket 10 and the upright 22. Then, align the four positioning rods 3 on the back of the UHF RFID all-in-one machine 1 with the corresponding sleeve holes of the bracket 10, insert the positioning rods 3 to achieve the initial positioning of the all-in-one machine, and then turn the second nut 17 on the threaded post 14 on the back of the bracket 10. The second nut pushes the slide 18 to slide along the threaded post 14 towards the bracket 10. When the slide 18 slides, it drives the rotating plate 20 to rotate through the pin shaft. The rotating plate 20 pushes the limit seat 13 to slide along the limit groove 12 towards the positioning rod 3. The limit seat 13 drives the locking post 16 on it to insert into the locking hole 15 of the positioning rod 3. The silicone rubber anti-slip ring 21 on the outer wall of the locking post 16 fits tightly with the inner wall of the locking hole 15 (increasing friction to prevent loosening). Tighten the second nut 17 to the appropriate torque, fix the position of the slide 18, and stably insert the locking post 16 into the locking hole 15 to complete the fixing of the UHF RFID all-in-one machine 1 and the bracket 10. Finally, connect the external power supply and signal equipment through the interface 2 at the bottom of the all-in-one machine, and the equipment can be put into use. During maintenance, the staff first disconnects the external connection of the integrated machine interface 2, and then uses a wrench to loosen the second nut 17 on the threaded column 14. The slide 18 resets under the elastic force of the polyurethane elastic sleeve 19. The reset of the slide 18 drives the rotating plate 20 to rotate in the opposite direction. The rotating plate 20 pulls the limit seat 13 to slide along the limit groove 12 away from the positioning rod 3. The limit seat 13 drives the locking column 16 to disengage from the locking hole 15 of the positioning rod 3. At this time, the UHF RFID integrated machine 1 can be directly pulled out from the bracket 10 (the positioning rod 3 disengages from the sleeve hole of the bracket 10). After maintenance, the installation steps described above are repeated to re-fix the integrated machine without disassembling the connection between the bracket 10 and the upright 22, which greatly improves maintenance efficiency.
