Description

Technical Field

[0001] This utility model relates to the field of readers, and in particular to a fixed RFID UHF reader. Background Technology

[0002] A reader / writer is a device used to read and write RFID tag information. It communicates with the tag by transmitting radio frequency signals to read, write, or modify tag data. Fixed RFID UHF readers / writers are used because they can efficiently and automatically identify multiple tags, reduce human error, have long-distance reading capabilities (up to several meters), are suitable for identifying large or moving objects, can adapt to harsh environments such as high temperature and humidity, ensure stable data collection, have excellent multi-tag reading capabilities, can process a large number of tags in a short time, meet real-time data requirements, can transmit data in real time for backend processing, and are easy to integrate with existing systems. They can achieve data sharing through multiple communication interfaces, improving system intelligence and management efficiency.

[0003] When a fixed RFID UHF reader is working, it first transmits radio frequency signals in the 860MHz-960MHz frequency band through its antenna to form an electromagnetic field. When an RFID tag enters this range, its antenna senses the signal and converts it into electrical energy to activate itself, transmitting the stored information back as a modulated radio frequency signal. After the reader's antenna receives the signal, the signal processing module demodulates it into a digital signal, and then decodes and parses the tag data. At the same time, it performs verification and error correction to ensure data accuracy. Finally, the reader connects to external devices to transmit the read data to the backend system, and can also perform operations such as writing to the tag according to the backend instructions.

[0004] With the widespread application of fixed RFID UHF readers, a rather thorny problem has gradually emerged. During the daily use of these devices, the continuous operation of their internal electronic components generates a large amount of heat. Existing heat dissipation designs often fail to meet the need for rapid heat dissipation, causing heat to accumulate inside the device. When the temperature exceeds a certain threshold, the device will experience performance degradation and data reading errors due to overheating, ultimately requiring shutdown for maintenance. This phenomenon greatly disrupts normal workflows, seriously affects the high efficiency that fixed RFID UHF readers should possess, and brings many inconveniences to industries such as warehousing and logistics, and manufacturing that rely on them for automated management. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fixed RFID UHF reader / writer, which aims to improve the problem of excessive internal heat causing the equipment to overheat and require shutdown for maintenance after prolonged operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fixed RFID ultra-high frequency reader / writer, including a housing, a base plate fixedly connected to one side of the housing, a transmission component provided on one side of the base plate, a plurality of fixing blocks fixedly connected to one side of the base plate, and a heat dissipation component provided on one side of the base plate;

[0007] The heat dissipation assembly includes a duct, multiple heat dissipation fins, and multiple fans. One side of the duct is fixedly connected to one side of the fixing block, the inner wall of each heat dissipation fin is fixedly connected to the outer wall of the duct, and the outer wall of each fan is fixedly connected to the inside of the housing.

[0014] As a further description of the above technical solution:

[0015] The connecting block is equipped with multiple springs. One end of each spring is fixedly connected to the inside of the connecting block, and the other end of each spring is fixedly connected to the bottom of the fixing pin.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the device is running, the heat generated inside it is absorbed into the air duct through the heat dissipation fins. At this time, the fan will start to extract this heat from the air duct, thereby reducing the temperature of the device during operation. This achieves the effect of absorbing the heat generated inside the device and extracting it from the device during use, avoiding the problem of the device overheating and needing to be shut down for maintenance due to excessive internal heat after prolonged use. This improves the efficiency of the fixed RFID UHF reader.

[0024] 2. In this utility model, first hold the blocking bar and rotate it to one side to unlock the connecting block. Then, hold the device and lift it upwards to disengage the connecting block from the connecting seat. After that, move the device to the desired position and slide the connecting block part of the device into the sliding groove on the connecting seat. This achieves the effect of easily moving the device to the desired position during use, avoiding the problem that the device cannot be easily moved to any desired position during use, thereby improving the practicality of the fixed RFID UHF reader.

[0032] 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.

[0033] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a fixed RFID UHF reader, comprising a housing 1, a base plate 2 fixedly connected to one side of the housing 1 for connecting a transmission component, a transmission component provided on one side of the base plate 2 for detecting and transmitting data, a plurality of fixing blocks 5 fixedly connected to one side of the base plate 2 for connecting a duct 6, and a heat dissipation component provided on one side of the base plate 2 for extracting heat from the inside of the device.

[0034] The heat dissipation assembly includes a duct 6, multiple heat dissipation fins 7, and multiple fans 8. One side of the duct 6 is fixedly connected to one side of the fixing block 5 to absorb the heat generated by the internal circuit board 3. The inner wall of each heat dissipation fin 7 is fixedly connected to the outer wall of the duct 6 to absorb the heat generated by the internal circuit board 3. The outer wall of each fan 8 is fixedly connected to the inside of the outer casing 1 to extract the absorbed heat. The transmission assembly includes a circuit board 3 and multiple interfaces 4. One side of the circuit board 3 is fixedly connected to one side of the base plate 2 to detect and record data. One end of each interface 4 is fixedly connected to the top of the outer casing 1 to communicate with other device circuits to transmit information.

[0035] Specifically, when the equipment is in continuous operation, the high-frequency operation of the internal electronic components generates a lot of heat. At this time, the heat dissipation fin 7 plays a key role. It has a large surface area and is made of high thermal conductivity material, which can quickly absorb the heat accumulated around it. This absorbed heat will then enter the air duct 6 connected to it. At the same time, the intelligent temperature control system detects the temperature rise and immediately triggers the fan 8 to start running. The fan 8 rotates at high speed and generates strong suction, which quickly draws out the hot air in the air duct 6, promoting a virtuous cycle of hot air outflow and cold air replenishment inside the equipment. This effectively lowers the temperature of the equipment during operation and ensures that the equipment operates stably and continuously.

[0036] Reference Figures 3-5A connecting block 9 is fixedly connected to one side of the base plate 2 for docking with the connecting seat 13. Multiple fixing pins 10 are slidably connected inside the connecting block 9 to fix the position of the blocking rod 16. A limit plate 11 is fixedly connected to the outer wall of each fixing pin 10 to limit the movement range of the fixing pin 10. The outer wall of each limit plate 11 is slidably connected inside the connecting block 9. Multiple springs 12 are provided inside the connecting block 9 to provide elastic force to the fixing pins 10. One end of each spring 12 is fixedly connected inside the connecting block 9, and the other end of each spring 12 is fixedly connected to... At the bottom of the fixing pin 10, a connecting seat 13 is slidably connected to the outer wall of the connecting block 9 for connecting to the connecting block 9 on one side of the equipment. A sliding groove 14 is provided on one side of the connecting seat 13 for accommodating the connecting block 9. Multiple rotating columns 15 are rotatably connected to the top of the connecting seat 13 for rotating the blocking rod 16. A blocking rod 16 is fixedly connected to the outer wall of each rotating column 15 to prevent the connecting block 9 from easily coming out. The rotating columns 15 are arranged in a symmetrical array on the top of the connecting seat 13, and the bottom of each blocking rod 16 is slidably connected to the top of the connecting seat 13.

[0037] Specifically, when it is necessary to change the position of the equipment, first hold the blocking rod 16 and rotate it smoothly to one side with a little force. As it rotates, the originally tightly engaged connecting block 9 and related structures gradually loosen, thereby unlocking it. At this time, hold the main body of the equipment with both hands and lift it vertically upwards slowly until the connecting block 9 is completely disengaged from the connecting seat 13. Then, move the equipment to the new position where it is expected to be used. After arriving at the new position, align the connecting block 9 at the bottom of the equipment with the sliding groove 14 on the connecting seat 13, and then slowly slide the connecting block 9 smoothly into the sliding groove 14. Finally, rotate the previously opened blocking rod 16 back to the top of the connecting block 9 so that it forms a stable block against the connecting block 9 again. In this way, the change of the equipment position is successfully completed.

[0038] Working principle: When using a fixed RFID UHF reader, the heat generated inside the device is absorbed by the heat sink 7 and enters the air duct 6. At this time, the fan 8 will start to draw this heat out from the air duct 6, thereby lowering the temperature of the device during operation. When it is necessary to change the position of the device, first hold the blocking bar 16 and rotate it to one side to unlock the connecting block 9. Then hold the device and lift it up to disengage the connecting block 9 from the connecting seat 13. After that, move the device to the desired position, slide the connecting block 9 into the sliding groove 14 on the connecting seat 13, and finally rotate the blocking bar 16 back to the top of the connecting block 9 to complete the change of the device position.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
