Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of radio frequency tags, and in particular relates to an RFID tag structure for managing glasses. Background Art
[0002] Radio frequency identification tags have been widely used in the retail and inventory counting of market products, but there are still some scenarios where it is impossible to completely avoid metal interference.
[0003] There are many types of eyeglass frames used in eyewear retail products, including full metal frames, semi-metal frames, and plastic frames. Conventional RFID tags have problems with shielding and reflection of communication signals in a metal backing environment. If anti-metal tags are used, firstly, the field pattern of the tag will have a half-field failure problem, causing the signal reading device to be unable to communicate with the RF signal at certain angles. Secondly, the cost of anti-metal tags is 5 to 10 times that of ordinary tags. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide an RFID tag structure for managing glasses, which is used to solve the technical problems in the prior art that the communication signals of conventional RFID tags in a metal backing environment will be shielded and reflected, and if anti-metal tags are used, there will be field type half-field failure and high cost.
[0005] The utility model solves the above technical problems with the following technical solutions: an RFID tag structure for managing glasses, comprising:
[0006] A face material, wherein at least two stress release holes are formed on the face material, and at least two of the stress release holes are simultaneously located on the same horizontal line or the same vertical line of the face material, and at least two of the stress release holes are used to allow the strips on the glasses to pass through;
[0007] An antenna, the antenna being disposed on the surface of the surface material, the antenna being adjacent to or intersecting the strip;
[0008] When the antenna intersects with the strip, the communication area of the antenna does not overlap with the strip in space, and the reflection area of the antenna overlaps with the strip in space;
[0009] A chip is arranged in the communication area of the antenna.
[0010] The utility model fixes the surface material on the strip of glasses through the stress release hole, so that the surface material can be kept flat and will not bend or deform to interfere with the signal; and the communication area of the antenna will not be interfered by the strip, and the communication effect will not be affected.
[0011] Further: when the antenna is adjacent to the strip, the reflection area of the antenna is arranged on both sides of the communication area, and the reflection area is a symmetrical dipole antenna arm;
[0012] When the antenna intersects with the strip, the reflection area of the antenna is arranged on one side of the communication area, and the reflection area is a sheet-shaped antenna arm.
[0013] The beneficial effects of adopting this step are as follows: when the strip is made of non-metallic material, a tag structure in which the antenna is adjacent to the strip is used, and the dipole antenna arm of the antenna itself is used to amplify the communication signal, which can generate a stronger signal and facilitate the reader to simultaneously receive communication signals from a large number of glasses; when the strip is made of metal, the reflective area of the antenna is used to couple with the strip to achieve the purpose of enhancing the communication signal, which also facilitates the reader to simultaneously receive communication signals from a large number of glasses.
[0014] Furthermore: the stress release hole is a triangular, circular, square or rice-shaped knife structure.
[0015] The beneficial effect of adopting this step is that the strip passes through the stress release hole, and the surface material is fixed on the strip.
[0016] Furthermore, the stress release hole may be a slot hole, the slot hole is located at the edge of the surface material, and at least one crack is formed from each slot hole to the edge of the surface material.
[0017] The beneficial effect of adopting this step is that the slot hole allows the strip to be inserted from the crack without having to extend it from one end.
[0018] Furthermore: the surface material is made of coated paper, PP synthetic paper or polyethylene.
[0019] The beneficial effects of adopting this step are: the above-mentioned material has high strength and good durability, which is convenient for long-term storage and application of radio frequency tags.
[0020] The beneficial effects of the utility model are:
[0021] There are at least two label plane release structure designs on the surface of the RFID tag (i.e. stress release holes, which keep the surface material of the RFID tag in a flat state). The antenna itself or the antenna reflection area is coupled with the back object to achieve secondary gain of the RF signal, thereby achieving the effect of amplifying the tag RF communication signal. It can identify more than 100 eyewear products. At the same time, the plane release structure design solves the problem of interference in the reading signal of the metal frame group, avoids damage and falling of the label caused by multiple trial wear, and enhances the comfort and satisfaction of customers trying on the products.

[0033] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.
[0034] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.
[0035] Example
[0036] like Figure 1 to Figure 4 As shown, the utility model provides an RFID tag structure for managing glasses, including:
[0037] A surface material 1, wherein at least two stress release holes 11 are formed on the surface material 1, and at least two of the stress release holes 11 are simultaneously located on the same horizontal line or the same vertical line of the surface material 1, and at least two of the stress release holes 11 are used to allow a strip 3 on the glasses to pass through, and the strip 3 is generally a structure of glasses such as the temples of the glasses or a horizontal strip connecting two frames;
[0038] Antenna 2, the antenna 2 is arranged on the surface of the surface material 1, and the antenna 2 is adjacent to or intersects with the strip 3;
[0039] When the antenna 2 intersects with the strip 3, the communication area 21 of the antenna 2 does not overlap with the strip 3 in space, and the reflection area 22 of the antenna 2 overlaps with the strip 3 in space;
[0040] The chip is arranged in the communication area 21 of the antenna 2 .
[0041] The utility model fixes the surface material 1 on the strip 3 of the glasses through the stress release hole 11, so that the surface material 1 can remain flat and will not bend or deform to cause signal interference; and the communication area 21 of the antenna 2 will not be interfered by the strip 3, and will not affect the communication effect.
[0042] On the basis of the above technical solution, when the antenna 2 is adjacent to the strip 3, the reflection area 22 of the antenna 2 is arranged on both sides of the communication area 21, and the reflection area 22 is a symmetrical dipole antenna arm;
[0043] When the antenna 2 intersects with the strip 3 , the reflection area 22 of the antenna 2 is arranged on one side of the communication area 21 , and the reflection area 22 is a sheet-shaped antenna arm.
[0044] When the strip 3 is made of non-metallic material, a tag structure in which the antenna 2 is adjacent to the strip 3 is used, and the dipole antenna arm of the antenna 2 itself is used to amplify the communication signal, which can generate a stronger signal and facilitate the reader to simultaneously receive communication signals from a large number of glasses; when the strip 3 is made of metal, the reflective area 22 of the antenna 2 is used to couple with the strip 3 to achieve the purpose of enhancing the communication signal, which also facilitates the reader to simultaneously receive communication signals from a large number of glasses.
[0045] like Figure 5 and Figure 6 As shown, based on the above technical solution, the stress release hole 11 is a triangular, circular, square or rice-shaped knife structure.
[0046] The strip 3 passes through the stress release hole 11 to fix the surface material 1 on the strip 3; the rice-shaped knife structure does not remove the material of the surface material 1 itself, but only forms open perforations. The material of the rice-shaped knife structure can limit the surface material 1 from sliding on the strip 3, so that the label will not cause damage or displacement of the product due to trial wearing or trial use after being hung on the eyewear product.
[0047] On the basis of the above technical solution, the stress release hole 11 can also be a slot hole, which is located at the edge of the surface material 1, and each of the slot holes has at least one crack opened to the edge of the surface material 1.
[0048] The slot hole allows the strip 3 to be inserted from the gap without having to be inserted from one end. This structure is suitable for connecting the RFID tag to the horizontal strip connecting the two frames.
[0049] On the basis of the above technical solution, the surface material 1 is made of coated paper, PP synthetic paper or polyethylene.
[0050] The above materials have high strength and good durability, which facilitates the long-term storage and application of radio frequency tags.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
