[0002] Barcode technology is mature and inexpensive, making it an indispensable identification technology for all goods. However, with the development of the Internet of Things (IoT), traditional barcodes, which only identify individual items, cannot meet the needs of people for rapid inventory counting. RFID electronic tags are a product of the IoT development and one of the core technologies in the IoT field.

[0003] Currently, the testing of RFID tags for electricity meters has been included in the full-performance testing scope before electricity meter supply. In the traditional testing process, RFID equipment needs to be manually operated to read the content of the RFID tag affixed to the back of the electricity meter nameplate, and then manually judged whether the content read by the RFID equipment matches the information on the electricity meter nameplate. This testing method is extremely inefficient in comparing the RFID tag content with the nameplate information, has low accuracy, and is prone to errors due to visual fatigue. Utility Model Content

[0044] Barcode technology is mature and inexpensive, making it an indispensable identification technology for all goods. However, with the development of the Internet of Things (IoT), traditional barcodes, which only identify individual items, cannot meet the needs of people for rapid inventory counting. RFID electronic tags are a product of the IoT development and one of the core technologies in the IoT field. They offer the advantage of long-distance, rapid, and batch identification, and RFID electronic tags support tens of thousands of write / erase cycles, storing more information than barcodes.

[0045] Currently, the testing of RFID tags for electricity meters has been included in the full-performance testing scope before electricity meter supply. In the traditional testing process, RFID equipment needs to be manually operated to read the content of the RFID tag affixed to the back of the electricity meter nameplate, and then manually judged whether the content read by the RFID equipment matches the information on the electricity meter nameplate. This testing method is extremely inefficient in comparing the RFID tag content with the nameplate information, has low accuracy, and is prone to errors due to visual fatigue.

[0046] Based on this, in order to solve the technical problems of low efficiency and poor accuracy of existing electricity meter detection methods, referring to Figures 1 to 4This utility model provides a detection component 10 for detecting product labels on electricity meters. The detection component 10 detects the product information of the electricity meter to ensure its accuracy. Specifically, a product label is provided on the surface of the electricity meter. The product label has a first surface wall and a second surface wall disposed opposite to each other. The first surface wall has a first information identifier, and the second surface wall has a second information identifier. For example, the first information identifier can be an external QR code or an external barcode, and the second information identifier can be an internal RFID tag. Only when the content information shown in the external QR code or external barcode and the internal RFID tag is consistent does the electricity meter meet the factory requirements. The detection component 10 includes a first detection element 100, a second detection element 200, and a control element. The first detection element 100 is used to detect and identify the first information identifier and generate first detection information. For example, corresponding to the first information identifier being an external QR code or external barcode, the first detection element 100 can be a barcode scanner. Through the barcode scanner, the content information recorded in the external QR code or external barcode can be detected and identified. The second detection element 200 is used to detect and identify the second information identifier and generate second detection information. For example, corresponding to the second information identifier being an internal RFID tag, the second detection element 200 can be an RFID device, which can detect and identify the content information recorded on the internal RFID tag. The control element is used to receive the first detection information generated by the first detection element 100 and the second detection information generated by the second detection element 200, and the control element can compare the first detection information and the second detection information and output the comparison result. For example, the control element may include a judgment module and a display module (the display module may include a display screen). Through the judgment module, the comparison of the first detection information and the second detection information can be realized, and through the display module, the comparison result of the first detection information and the second detection information can be output and displayed for on-site inspection by operators.

[0047] Specifically, in this embodiment, when performing product information detection on the electricity meter, the electricity meter is first transported to the detection component 10 with the product label exposed. Then, the first detection element 100 detects and identifies the first information identifier on the product label and transmits the generated first detection information to the control element. Next, the second detection element 200 detects and identifies the second information identifier on the product label and transmits the generated second detection information to the control element. Finally, the control element compares the first and second detection information. When the first and second detection information match, the electricity meter proceeds normally to the next step. When the first and second detection information do not match, the electricity meter is marked to facilitate sorting out the meter, thereby improving the factory accuracy of the electricity meter.

[0048] The detection component 10 provided in this embodiment enables automated detection of electricity meters. Compared to manual detection, this component 10 improves detection efficiency and accuracy, reduces errors caused by human factors, and is simple, efficient, time-saving, and labor-saving. Furthermore, the component 10 automatically collects and records RFID tag information from the electricity meter, facilitating data traceability and ensuring timely and efficient resolution of any errors.

[0049] In some embodiments, refer to Figures 1 to 4 The detection assembly 10 includes a support frame 300, which has a first sliding portion 310. A first detection element 100 is connected to a second sliding portion 110, and the second sliding portion 110 and the first sliding portion 310 are slidably connected. For example, the first sliding portion 310 can be a slide rail, and the second sliding portion 110 can be a slide groove 311. The sliding connection between the first sliding portion 310 and the second sliding portion 110 is achieved through the cooperation between the slide rail and the slide groove 311. Alternatively, a similar structure can be used: the first sliding portion 310 can be a slide groove 311, and the second sliding portion 110 can be a slide rail. The second sliding portion 110 is driven by a first driving mechanism, which is configured to drive the second sliding portion 110 to move along the first sliding portion 310, causing the first detection element 100 to move towards or away from the energy meter. For example, the first driving mechanism can be a drive motor.

[0050] Specifically, in this embodiment, when the first detection element 100 detects and identifies the first information identifier, the first driving mechanism rotates forward, causing the first detection element 100 to move closer to the energy meter, thereby reducing the distance between the first detection element 100 and the first information identifier and improving the detection and identification accuracy of the first information identifier. After the first detection element 100 has finished detecting the energy meter, the first driving mechanism rotates backward, causing the first detection element 100 to move away from the energy meter, thereby ensuring that the first detection element 100 does not falsely detect energy meters that do not need to be detected, and improving the order of energy meter detection.

[0051] Through the cooperation between the first sliding part 310 and the second sliding part 110, the first detection element 100 can move towards or away from the energy meter. On the one hand, the first sliding part 310 can provide guidance for the second sliding part 110, thereby improving the movement accuracy of the first detection element 100 and preventing the first detection element 100 from deviating during movement. On the other hand, relying on the cooperation between the first sliding part 310 and the second sliding part 110, it is beneficial to improve the movement sensitivity of the first detection element 100 and prevent the first detection element 100 from experiencing movement lag.

[0052] In some embodiments, refer to Figures 1 to 4 The first sliding part 310 includes a groove 311, and the second sliding part 110 includes a roller (not shown in the figure), which is connected to the groove 311. For example, the first sliding part 310 may include multiple grooves 311, and correspondingly, the second sliding part 110 may include multiple rollers, each roller being connected to each groove 311.

[0053] Specifically, in this embodiment, when the second sliding part 110 moves along the first sliding part 310, the roller moves within the groove 311. This structure effectively reduces the friction between the second sliding part 110 and the first sliding part 310, transforming some of the sliding friction into rolling friction. This improves the smoothness and efficiency of the second sliding part 110's movement, ensuring the motion accuracy and efficiency of the first detection element 100. Furthermore, by providing the roller, wear between the second sliding part 110 and the first sliding part 310 can be reduced, extending the service life of the detection assembly 10 and lowering its maintenance costs.

[0054] In some embodiments, refer to Figures 1 to 4The detection assembly 10 includes a support frame 300, which has a rotating arm 320 and a fixed bracket 330. The fixed bracket 330 is connected to one end of the rotating arm 320 and is used to mount the second detection element 200. The rotating arm 320 is driven by a second drive mechanism configured to drive the rotating arm 320 to rotate, causing the rotating arm 320 to move the second detection element 200 towards or away from the energy meter. For example, the second drive mechanism can be a rotary motor. Preferably, the angle α by which the second drive mechanism drives the rotating arm 320 to rotate satisfies: 0° ≤ α ≤ 90°. For example, the value of α can be 0°, 45°, 90°, etc. When the angle α is 0°, the second detection element 200 can be in a repositioned state; when the angle α is 90°, the second detection element 200 can be in a detection state.

[0055] Specifically, in this embodiment, when the second detection element 200 detects and identifies the second information identifier, the second drive mechanism rotates clockwise. At this time, the second drive mechanism drives the rotating arm 320 to rotate from 0° to 90°. The rotating arm 320 causes the second detection element 200 to switch from a avoidance state to a detection state, causing the second detection element 200 to move closer to the energy meter, thereby reducing the distance between the second detection element 200 and the second information identifier and improving the detection and identification accuracy of the second information identifier. After the second detection element 200 has finished detecting the energy meter, the second drive mechanism reverses direction. At this time, the second drive mechanism drives the rotating arm 320 to rotate from 90° to 0°. The rotating arm 320 causes the second detection element 200 to switch from a detection state to a avoidance state, causing the second detection element 200 to move away from the energy meter, thereby ensuring that the second detection element 200 does not falsely detect energy meters that do not need to be detected, and improving the order of energy meter detection.

[0056] In some embodiments, the fixed bracket 330 is provided with a first connecting hole, and the second detection element 200 is provided with a second connecting hole. A connector is sequentially inserted into the second connecting hole and the first connecting hole, and the connector is used to detachably connect the second detection element 200 and the fixed bracket 330. For example, the first connecting hole and the second connecting hole may be provided with internal threads, and the connector may be provided with external threads. Through the cooperation between the internal threads and the external threads, the connector can be threadedly connected in the first connecting hole and the second connecting hole, thereby realizing the threaded connection between the second detection element 200 and the fixed bracket 330.

[0057] Specifically, in this embodiment, when the second detection element 200 is installed on the fixed bracket 330, the second connecting hole and the first connecting hole are first aligned, and then a connector is sequentially inserted into the second connecting hole and the first connecting hole. By tightening the connector into the second connecting hole and the first connecting hole, a secure connection between the second detection element 200 and the fixed bracket 330 can be achieved. When the second detection element 200 is removed from the fixed bracket 330, the connector is loosened and removed from the first connecting hole and the second connecting hole, thereby separating the second detection element 200 from the fixed bracket 330.

[0058] The above connection method is simple in structure and easy to operate. It can ensure the connection stability between the second detection element 200 and the fixed bracket 330, prevent the second detection element 200 from detaching from the fixed bracket 330 during rotation, and facilitate the installation, disassembly and replacement of the second detection element 200 and the fixed bracket 330, saving time and effort.

[0059] In some embodiments, the fixed bracket 330 is provided with a snap-fit ​​hole, and the second detection element 200 is provided with a snap-fit ​​post. The snap-fit ​​post and the snap-fit ​​hole are connected to each other to achieve snap-fit ​​between the second detection element 200 and the fixed bracket 330. For example, when the snap-fit ​​post is connected in the snap-fit ​​hole, the snap-fit ​​post and the snap-fit ​​hole are interference fit. Alternatively, a first magnetic attraction part is provided in the snap-fit ​​hole, and a second magnetic attraction part is provided on the side peripheral wall and end of the snap-fit ​​post. When the snap-fit ​​post is connected in the snap-fit ​​hole, the snap-fit ​​post can be stably connected in the snap-fit ​​hole through the magnetic attraction between the second magnetic attraction part and the first magnetic attraction part.

[0060] Specifically, in this embodiment, a stable connection between the second detection element 200 and the fixed bracket 330 can be achieved by engaging the snap-fit ​​pin within the snap-fit ​​hole. Separation between the second detection element 200 and the fixed bracket 330 can be achieved by removing the snap-fit ​​pin from the snap-fit ​​hole. This connection method facilitates the processing and forming of the second detection element 200 and the fixed bracket 330, and saves operating space, for example, eliminating the need to reserve space for tightening nuts, bolts, etc. Furthermore, this connection method improves the assembly efficiency between the second detection element 200 and the fixed bracket 330, saves assembly time, and ensures the connection stability between the second detection element 200 and the fixed bracket 330.

[0061] In some embodiments, the inner ring of the fixing bracket 330 is provided with a first magnetic attraction part, and the outer periphery of the second detection element 200 is provided with a second magnetic attraction part. Through the cooperation between the second magnetic attraction part and the first magnetic attraction part, a magnetic connection between the second detection element 200 and the fixing bracket 330 can be achieved. Using the above connection method, a non-destructive connection between the second detection element 200 and the fixing bracket 330 can be achieved, ensuring that the structure of the second detection element 200 and the fixing bracket 330 is not damaged during assembly and disassembly.

[0062] In some embodiments, refer to Figures 1 to 4 The detection component 10 includes a detection position 11, to which the energy meter is transported by a transmission mechanism. For example, the transmission mechanism can be a conveyor belt. Specifically, in this embodiment, multiple energy meters can be loaded onto the transmission mechanism at once, allowing the mechanism to sequentially transport each energy meter to the detection position 11 for detection. This facilitates batch detection of energy meters, improves detection efficiency, and saves detection time. Furthermore, the above process reduces manual intervention, lowers errors during detection, improves accuracy, and enhances automation.

[0063] In some embodiments, refer to Figures 1 to 4 The detection assembly 10 includes a support frame 300, on which a position sensing element 340 (i.e., a position sensor) is provided. The position sensing element 340 is used to detect and determine that the energy meter has reached the detection position 11. For example, the sensing part of the position sensing element 340 can be directly facing the detection position 11.

[0064] Specifically, in this embodiment, when the position sensing element 340 senses that the energy meter has moved to the detection position 11, the position sensing element 340 can send a signal to the transmission mechanism and control the transmission mechanism to stop moving, so that the energy meter stays at the detection position 11. At this time, the first detection element 100 and the second detection element 200 can accurately detect the energy meter. After the energy meter detection is completed, the control element can control the transmission mechanism to restart, realize the further transmission of the energy meter, and ensure the orderly progress of the energy meter detection.

[0065] Correspondingly, another embodiment of this utility model also provides a testing device, which includes the testing component 10 in any of the above embodiments. The testing device also includes a transmission mechanism for transporting the electricity meter to the testing component 10. For example, the transmission mechanism can be a conveyor belt. The testing device may also include a sorting component. After the electricity meter completes testing at the testing component 10, it can be transported to the sorting component via the transmission mechanism. The sorting component can centrally classify the electricity meters that pass and fail the test, thereby improving the yield rate of the electricity meters.

[0066] Specifically, in this embodiment, the detection equipment using the detection component 10 described above can improve the automation level of electricity meter detection and realize batch detection of electricity meters. Moreover, the detection equipment using the detection component 10 described above can improve the detection accuracy of electricity meters and prevent detection errors caused by human interference.

[0067] Thanks to the improvements to the detection component 10, the detection device of this embodiment has the same technical effect as the detection component 10, which will not be described again here.

[0068] It should be noted that other contents of the detection component 10 and detection equipment disclosed in this utility model can be found in the prior art, and will not be repeated here.

[0069] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
