Description

An RFID tag encapsulation structure Technical Field

[0001] This utility model relates to the field of electronic tag technology, and in particular to an RFID tag packaging structure. Background Technology

[0002] RFID (Radio Frequency Identification) tags are data carriers used for item identification, with information storage mechanisms, capable of receiving electromagnetic field modulation signals from readers and returning response signals. They are commonly referred to as electronic tags, and can also be called radio frequency cards, radio frequency tags, radio frequency labels, etc. They, together with readers, constitute the hardware core of an RFID system.

[0003] Existing RFID tags are typically made by heating, pressing and punching an inner layer of INLAY sheet and two PVC materials on the top and bottom. When the chip protrudes above the antenna plane, the PVC material seals around the antenna during lamination, preventing the chip from being squeezed and thus avoiding crushing.

[0004] Although this laminated packaging structure is relatively tight, the edges of the two PVC materials are glued together, making it difficult to disassemble and repair when the chip or antenna is damaged, thus reducing the maintainability of the RFID tag. Summary of the Invention

[0005] Therefore, the purpose of this utility model is to provide an RFID tag packaging structure that allows for easy disassembly of the RFID tag.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides an RFID tag packaging structure, including a shell, a middle material assembly, a first elastic layer, a protective layer, a retaining buckle, and a cover. The shell has a receiving cavity and an opening communicating with the receiving cavity. The middle material assembly is disposed in the receiving cavity. The first elastic layer is located in the receiving cavity and covers the middle material assembly. The protective layer is located in the receiving cavity and covers the first elastic layer. The peripheral surface of the protective layer is sealed to the side wall of the receiving cavity. The retaining buckle is elastically rotatably disposed on the shell. Multiple retaining buckles are provided and are spaced apart circumferentially along the opening. The cover closes the opening. When the cover closes the opening, the cover abuts against the retaining buckle until it presses against the surface of the protective layer facing the opening.

[0008] In addition, the RFID tag packaging structure described above according to this utility model may also have the following additional technical features:

[0009] Furthermore, the RFID tag's encapsulation structure also includes a second elastic layer, which is located in the accommodating cavity and abuts against the bottom of the accommodating cavity, with the material assembly sandwiched between the first elastic layer and the second elastic layer.

[0010] Furthermore, both the first elastic layer and the second elastic layer are made of rubber material.

[0011] Furthermore, the portion of the housing corresponding to the first elastic layer and the second elastic layer is recessed inward to form a snap-fit ​​portion.

[0012] Furthermore, the portion of the bayonet located within the accommodating cavity is flat, so as to simultaneously press against a portion of the peripheral surface of the first elastic layer and the second elastic layer.

[0013] Furthermore, the pressure buckle includes an arc-shaped plate, a rotating shaft, and a torsion spring. The rotating shaft is connected to one end of the arc-shaped plate and is pivotally connected to the housing. The torsion spring is sleeved on the rotating shaft, with one end of the torsion spring abutting against the arc-shaped plate and the other end abutting against the housing.

[0014] Furthermore, the protective layer includes a first sealing cover and a second sealing cover that interlock with each other. The first sealing cover has a groove that engages with the end of the arc-shaped plate away from the rotating shaft.

[0015] Furthermore, the first sealing cover has an annular groove on the side near the second sealing cover, and the second sealing cover has a retaining ring that matches the groove; or the second sealing cover has an annular groove on the side near the first sealing cover, and the first sealing cover has a retaining ring that matches the groove.

[0016] Furthermore, the first sealing cover and / or the second sealing cover have an annular groove on their circumferential surface, and a sealing ring is provided in the annular groove.

[0017] Furthermore, the housing is threadedly connected to the cover.

[0018] The beneficial effects of this invention include at least the following: When the cover is opened, the retaining buckle is positioned outside the opening under the elastic force, thus preventing it from interfering with the opening and facilitating the removal and installation of the intermediate material component; when the cover is closed, the cover pushes one end of the retaining buckle to rotate relative to the housing and towards the inside of the opening until the other end of the retaining buckle presses against the upper surface of the protective layer, thereby compacting the intermediate material component, the first elastic layer, and the protective layer, ensuring good airtightness. Furthermore, the first elastic layer provides a certain degree of cushioning and shock absorption, thus protecting the intermediate material component to some extent. Attached Figure Description

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0026] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please refer to Figures 1 to 3 for an RFID tag packaging structure provided by this utility model, which includes a shell 100, a middle material component 200, a first elastic layer 300, a protective layer 400, a pressure buckle 500, and a cover 600.

[0029] Specifically, the housing 100 has a receiving cavity 110, and the housing 100 has an opening 120 communicating with the receiving cavity 110. The intermediate material assembly 200 is disposed in the receiving cavity 110. The first elastic layer 300 is located in the receiving cavity 110 and covers the intermediate material assembly 200, providing shock absorption and protection for the chip and antenna in the intermediate material assembly 200. The protective layer 400 is located in the receiving cavity 110 and covers the first elastic layer 300, with the peripheral surface of the protective layer 400 being flush with the receiving cavity 110. The sidewall of the 0 is sealed to prevent moisture and dust in the air from entering the space where the material assembly 200 is placed. The pressure buckle 500 is elastically rotatably mounted on the housing. Multiple pressure buckles 500 are provided and are spaced apart circumferentially along the opening 120. The cover 600 covers the opening to protect the components inside the accommodating cavity 110. At the same time, the cover 600 also plays a fixing role. For example, an adhesive layer is provided on the outer surface of the cover 600 to fix the RFID tag to the work object.

[0030] In this embodiment, when the cover 600 is not covering the opening 120, the pressure buckle 500 is located outside the opening 120 under the elastic force, so that the pressure buckle 500 will not interfere with the opening 120, which facilitates the installation of the middle material assembly 200, the first elastic layer 300 and the protective layer 400 into the accommodating cavity 110; when the cover 600 covers the opening 120, the cover 600 pushes one end of the pressure buckle 500 to rotate relative to the housing 100 and rotate towards the inside of the opening 120 until the other end of the pressure buckle 500 presses against the upper surface of the protective layer 400.

[0031] To avoid hard contact between the middle material component 200 and the bottom of the accommodating cavity 110, in some optional embodiments, as shown in FIG2, the RFID tag encapsulation structure further includes a second elastic layer 700. The second elastic layer 700 is located inside the accommodating cavity 110 and abuts against the bottom of the accommodating cavity 110. The middle material component 200 is sandwiched between the first elastic layer 300 and the second elastic layer 700, thereby achieving full protection for the middle material component 200.

[0032] In some optional embodiments, the first elastic layer 300 and the second elastic layer 700 are both made of rubber material. The flexibility of the rubber material allows the first elastic layer 300 and the second elastic layer 700 to adapt to the shape of the chip and antenna in the intermediate material assembly 200, while also providing good shock absorption for the chip and antenna in the intermediate material assembly 200.

[0033] To prevent the first elastic layer 300 and the second elastic layer 700 from moving radially, in some optional embodiments, as shown in Figures 1 and 2, the housing 100 is recessed inward at the portion corresponding to the first elastic layer 300 and the second elastic layer 700 to form a latch 130. The space formed by the inward compression of the latch 130 can, to a certain extent, restrict the radial movement of the first elastic layer 300 and the second elastic layer 700.

[0034] In some alternative embodiments, as shown in FIG2, the portion of the latch 130 located within the receiving cavity 110 is flat. The flat latch 130 simultaneously presses against a portion of the circumferential surface of the first elastic layer 300 and the second elastic layer 700, thereby further restricting the radial movement of the first elastic layer 300 and the second elastic layer 700.

[0035] In some optional embodiments, as shown in FIG3, the pressure buckle 500 includes an arc-shaped plate 510, a rotating shaft 520, and a torsion spring 530. A rotating seat 140 is provided on the housing 100, and the rotating shaft 520 passes through the rotating seat 140, so that the rotating shaft 520 can rotate on the rotating seat 140. The rotating shaft 520 is fixedly connected to one end of the arc-shaped plate 510, and the torsion spring 530 is sleeved on the rotating shaft 520. One end of the torsion spring 530 abuts against the arc-shaped plate 510. For example, a limiting groove for limiting the end of the torsion spring 530 can be provided on the arc-shaped plate 510. The other end of the torsion spring 530 abuts against the rotating seat 140. For example, a limiting groove for limiting the end of the torsion spring 530 can be provided on the rotating seat 140.

[0036] In this embodiment, when the cover 600 is not covering the opening 120, under the elastic force generated by the torsion spring 530, the arc plate 510 rotates to the outside of the opening 120. In this way, the arc plate 510 will not interfere with the opening 120, making it convenient to install the middle material assembly 200, the first elastic layer 300, and the protective layer 400 into the accommodating cavity 110. When the cover 600 covers the opening 120, the cover 600 presses the arc plate 510 downward, causing the arc plate 510 to rotate to the inside of the opening 120 until the other end of the arc plate 510 is tightly pressed against the upper surface of the protective layer 400. At this time, if the cover 600 is opened, under the elastic force generated by the torsion spring 530, the arc plate 510 will immediately rotate to the outside of the opening 120.

[0037] To prevent positional deviation of the protective layer 400 when the other end of the curved plate 510 is firmly pressed against the upper surface of the protective layer 400, and to avoid positional deviation of the protective layer 400, in some optional embodiments, as shown in FIG2, the protective layer 400 includes a first sealing cap 410 and a second sealing cap 420 that interlock with each other. The first sealing cap 410 is provided with a groove 411, which is engaged with the end of the curved plate 510 away from the rotating shaft 520. By providing the first sealing cap 410 and the second sealing cap 420, it is convenient to assemble the protective layer 400 by stacking. At the same time, when one of the sealing caps is damaged, only the corresponding one needs to be replaced, without replacing the entire protective layer 400, thus reducing manufacturing costs.

[0038] In some optional embodiments, as shown in FIG2, the first sealing cover 410 has an annular groove 412 on the side near the second sealing cover 420, and the second sealing cover 420 has a retaining ring 421 that matches the groove 412, thereby achieving a locking connection between the two and preventing relative sliding between the first sealing cover 410 and the second sealing cover 420. It is understood that the second sealing cover 420 may also have an annular groove 412 on the side near the first sealing cover 410, and the first sealing cover 410 may have a retaining ring 421 that matches the groove 412.

[0039] To prevent external moisture and dust from entering the space containing the intermediate material assembly 200 from the edges of the first sealing cover 410 and the second sealing cover 420, in some optional embodiments, an annular groove (not shown in the figures) is provided on the circumferential surface of the first sealing cover 410, and a sealing ring (not shown in the figures), such as a rubber sealing ring, is provided in the annular groove. It is understood that an annular groove can also be provided on the circumferential surface of the second sealing cover 420, or both the first and second sealing covers 410 can be provided simultaneously. This ensures good sealing between the edge of the first sealing cover 410 and the sidewall of the receiving cavity 110, or good sealing between the edge of the second sealing cover 420 and the sidewall of the receiving cavity 110, or good sealing between the edges of both the first and second sealing covers 410 and the sidewall of the receiving cavity 110.

[0040] In some optional embodiments, the housing 100 and the cover 600 are threadedly connected. Specifically, an external thread can be provided on the outside of the housing 100, and a corresponding internal thread can be provided on the inside of the cover 600. Optionally, the housing 100 can be rectangular, circular, or other shapes, and the cover 600 can also be rectangular, circular, or other shapes.
