Description

Technical Field

[0001] This utility model relates to the field of metal nameplate labels, and more specifically, it relates to a deformation-resistant metal nameplate RFID tag. Background Technology

[0002] Metal nameplate RFID tags are identification carriers primarily made of metal. They typically consist of upper and lower metal plates (such as aluminum, stainless steel, copper, etc.) and an RFID radio frequency tag layer in the middle. The metal plates serve as physical support and display carriers, and can present visual identification information such as text and patterns through processes such as etching and printing. The middle RFID radio frequency tag layer has the function of storing and transmitting electronic data, and can conduct non-contact data interaction with reading and writing devices through radio frequency signals, realizing intelligent management such as item identification, information traceability, and status tracking. This design, which combines the visual identification function of traditional metal nameplates with the data interaction capability of RFID technology, makes it widely used in fields such as industrial equipment identification, asset management, and product traceability, combining the dual advantages of human visual identification and automated data collection.

[0003] However, during the riveting process of traditional metal nameplates, the upper and lower metal plates are prone to local deformation due to the riveting force, which causes the RFID tag layer sandwiched between them to be squeezed, resulting in deformation or even damage, affecting the normal use of its data storage and transmission functions. Furthermore, due to the lack of an effective fixing and protection structure, the position of the RFID tag layer between the metal plates is prone to shift, reducing the overall reliability and service life of the metal nameplate tag (after shifting, the RFID tag layer is prone to friction and squeezing with the metal plate, and may wear and break under long-term external forces such as vibration), making it difficult to meet the stability and durability requirements of scenarios such as industrial equipment identification and asset management.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a deformation-resistant metal nameplate RFID tag. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a deformation-resistant metal nameplate RFID tag.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant metal nameplate RFID tag, comprising two parallel metal plates, and an RFID radio frequency tag layer sandwiched between the two metal plates. A structural component is also installed between the metal plates. Riveting holes are provided at the edges of both the metal plates and the structural component. The outer periphery of the structural component is adapted to the outer periphery of the metal plates. An embedding slot for accommodating the RFID radio frequency tag layer is provided in the middle of the structural component. The RFID radio frequency tag layer is embedded in the embedding slot of the structural component to prevent deformation of the RFID radio frequency tag layer during the riveting process.

[0007] Preferably, rubber sheets are provided on the upper and lower sides of the RFID radio frequency tag layer, and the rubber sheets are also embedded in the mounting groove.

[0008] Preferably, the rubber sheet has protrusions on both sides, and the structural member has openings on both sides that allow the protrusions to pass through and are perpendicularly connected to the mounting groove, thereby limiting the rubber sheet through a convex-concave fit.

[0009] Preferably, grooves for limiting the RFID radio frequency tag layer are formed on the opposite surfaces of the two rubber sheets.

[0010] Preferably, an engineering plastic sheet is also provided between the back of the RFID radio frequency tag layer and the rubber sheet.

[0011] Preferably, the rubber sheet is made of silicone rubber with a Shore hardness of 40 to 60 A.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When riveting force is applied to the upper and lower metal plates through the riveting holes, the rigid structural component adapted to the outer contour of the metal plate first bears and disperses the lateral shear force generated by riveting, preventing the metal plate from directly squeezing the RFID tag layer. At the same time, the embedded through groove in the middle of the structural component fixes the RFID tag layer in a precise position through shape limiting. The groove wall forms physical support for the edge of the RFID tag layer, preventing it from shifting or bending during the riveting process. In addition, the depth design of the embedded through groove ensures that a small gap is maintained between the RFID tag layer and the metal plate, further buffering the longitudinal pressure that may be generated during riveting. Thus, through the stress transfer of the structural component and the mechanical limiting effect of the embedded through groove, the problem of the RFID tag layer being easily squeezed and deformed and easily shifted during the riveting of traditional nameplates in the background art is effectively solved.

[0014] 2. The rubber sheet of this utility model absorbs the longitudinal extrusion force generated by the metal plate during the riveting process by utilizing its own elastic deformation, and avoids edge indentation or bending of the RFID radio frequency tag layer due to rigid contact through flexible support.

[0015] 3. The present invention also provides a groove on the opposite surface of the rubber sheet to limit the RFID radio frequency tag layer. The length and width of the groove are precisely matched with the RFID radio frequency tag layer. When the RFID radio frequency tag layer is embedded, the inner wall of the groove generates radial pressure through elastic deformation, forming a self-centering effect, ensuring that the RFID radio frequency tag layer remains in the center position in the mounting groove, and preventing the RFID radio frequency tag layer from shifting due to slight misalignment of the metal plate during the riveting process.

[0016] 4. This utility model can increase the bending strength of the RFID radio frequency tag layer by 2-3 times through engineering plastic sheet, effectively resisting the longitudinal bending force generated by the deformation of the metal plate during the riveting process.

[0023] like Figure 1-3As shown, this utility model provides a deformation-resistant metal nameplate RFID tag, including two parallel metal plates 1, and an RFID radio frequency tag layer 2 sandwiched between the two metal plates 1. A structural component 3 is also installed between the metal plates 1. Riveting holes 4 are provided at the edges of both the metal plates 1 and the structural component 3. The outer periphery of the structural component 3 is adapted to the outer periphery of the metal plates 1. An embedding slot 301 for accommodating the RFID radio frequency tag layer 2 is provided in the middle of the structural component 3. The RFID radio frequency tag layer 2 is embedded in the embedding slot 301 of the structural component 3.

[0024] This utility model is based on the structural component 3 for dispersing riveting stress and the embedded protection of the RFID tag layer 2: When riveting force is applied to the upper and lower metal plates 1 through the riveting hole 4, the rigid structural component 3, which is adapted to the outer contour of the metal plate 1, first bears and disperses the transverse shear force generated by riveting, preventing the metal plate 1 from directly squeezing the RFID tag layer 2; at the same time, the embedded through groove 301 in the middle of the structural component 3 fixes the RFID tag layer 2 in a precise position through shape limiting, and the groove wall forms physical support for the edge of the RFID tag layer, preventing it from shifting or bending during the riveting process. In addition, the depth design of the embedded through groove 301 ensures that a small gap is maintained between the RFID tag layer and the metal plate, further buffering the longitudinal pressure that may be generated during riveting, thereby achieving the dual effects of stress transfer of the structural component 3 and mechanical limiting of the embedded through groove 301.

[0025] Furthermore, rubber sheets 5 are provided on both the top and bottom sides of the RFID tag layer 2, and the rubber sheets 5 are also embedded in the mounting groove 301. The rubber sheets 5 absorb the longitudinal extrusion force generated by the metal plate 1 during the riveting process by utilizing their own elastic deformation. Through flexible support, they prevent edge indentations or bending of the RFID tag layer 2 caused by rigid contact. In addition, protrusions 501 are provided on both sides of the rubber sheets 5, and the structural component 3 has openings 302 on both sides that allow the protrusions 501 to pass through and are perpendicularly connected to the mounting groove 301. After the rubber sheets 5 are installed in the mounting groove 301, the protrusions 501 also pass through the openings 302, forming a concave-convex fit structure. The concave-convex fit limits the rubber sheets 5 and prevents them from sliding laterally in the mounting groove 301. Especially when the metal plate 1 undergoes slight deformation during the riveting process, the displacement of the rubber sheets 5 can be controlled within 0.1 mm. Within this range, it ensures that it always adheres to the RFID tag layer 2 and provides uniform cushioning, avoiding localized stress concentration on the RFID tag layer 2 due to displacement of the rubber sheet 5.

[0026] Among them, the rubber sheet 5 is made of transparent silicone rubber with a Shore hardness of 40 to 60A. Silicone rubber in this hardness range has both good elasticity and structural support. It can effectively absorb the deformation energy of the metal plate 1 during the riveting process, while avoiding insufficient support for the RFID radio frequency tag layer 2 due to excessive softness.

[0027] Furthermore, this utility model also provides a groove 502 on the opposite surface of the rubber sheet 5 to limit the RFID tag layer 2. The length and width of the groove 502 are precisely matched with the RFID tag layer 2. When the RFID tag layer 2 is embedded, the inner wall of the groove 502 generates radial pressure through elastic deformation, forming a self-centering effect, ensuring that the RFID tag layer 2 remains in the center position in the mounting slot 301, preventing the RFID tag layer 2 from shifting due to slight misalignment of the metal plate 1 during the riveting process. An engineering plastic sheet 6 is also provided between the back of the RFID tag layer 2 and the rubber sheet 5. The engineering plastic sheet 6 is made of rigid materials such as ABS and PC, which can increase the bending strength of the RFID tag layer 2 by 2-3 times, effectively resisting the longitudinal bending force generated by the deformation of the metal plate 1 during the riveting process.

[0028] The RFID radio frequency tag layer 2 is an RFID electronic tag inlay. This anti-deformation metal nameplate tag can effectively protect the extremely thin inlay, which is easily damaged by external forces, by using a three-layer protective structure consisting of an embedded through groove 301, a rubber sheet 5, and an engineering plastic sheet 6, while retaining the original structural advantages.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
