Abstract
Description
Technical Field
[0001] The invention relates to the technical field of insulator processing, in particular to an electronic tag and a preparation method thereof. Background Art
[0002] Electronic tags, also known as transponders or data carriers, are contactless sensing technologies that use radio frequency signals to identify labels, track items, and collect information. RFID technology has been widely used in logistics, air parcels, production lines, warehousing, sales channels, valuables, and biomedicine, among other industries.
[0003] Chinese patent CN201610735431.1 discloses an RFID electronic tag for metal, non-metal and liquid made by ceramic lamination, including a ground dielectric layer for improving identification performance, a ceramic layer laminated on the upper side of the ground dielectric layer, an antenna formed on the upper side of the ceramic layer, and a Tag chip placed on the upper side of the ceramic layer and electrically connected to the antenna. The Tag chip and the antenna are provided with an insulating layer outside. By utilizing a ceramic layer with a high dielectric constant, it is possible to make a very small Tag and reduce the size of the Tag.

[0038] The widespread use of electronic tags in the pharmaceutical industry faces a problem: after all the production process steps, the plastic bottles filled with medicines must pass through a 230°C heating device to fuse the tin foil with the plastic bottles and seal them before they can be put into storage. Since paper electronic tags are attached to plastic bottles and have many layers, after being exposed to a high temperature of 230°C and the heat of the antenna itself, the printed surface of the label melts and is damaged.
[0039] like Figure 1-2 As shown, this embodiment provides an electronic tag, including a surface material 1 and a backing paper 3 arranged opposite to each other, a colloid 2 and an antenna 4 are arranged between the surface material 1 and the backing paper 3, the antenna 4 is bonded to the bottom of the surface material 1, and a chip 5 is arranged on the side of the antenna 4 facing away from the surface material 1;
[0040] Colloid 2 is specifically a colloid made of acrylic polymer and rayon non-imitation cloth, and the ratio of acrylic polymer to rayon non-imitation cloth is 93-95:5-7;
[0041] The antenna 4 includes an annular ring 41, a trapezoidal notch is provided on one side of the annular ring 41, the chip 5 is arranged on the inner side of the notch of the annular ring 41, a connecting piece 44 is provided on the side of the annular ring 41 away from the annular ring 41, a group of rotating rings 42 are provided at both ends of the connecting piece 44, and the rotating ring 42 is connected to the sub-piece 43 at one end facing the ion sheet 43.
[0042] Specifically, the electronic tag only has the structure of the surface material 1, the antenna 4 and the backing paper 3, which effectively simplifies the structure of the electronic tag, so that the electronic tag can effectively avoid the problem of damage to the multi-layer structure after heating.
[0043] Furthermore, the surface material 1 is specifically a polyimide thermal transfer material, and the ratio of the acrylic polymer to the rayon non-imitation cloth is 94:6.
[0044] Specifically, acrylic polymer and rayon non-imitation cloth, when made into colloid according to this ratio, can fall off without solidifying at high temperature, and this colloid can ensure that the electronic tag has sufficient flexibility during use.
[0045] It will be appreciated that the total amount of the acrylic polymer and the rayon polyester is 100.
[0046] Furthermore, a metal layer is provided on the side of the antenna 4 facing away from the surface material 1 .
[0047] It should be noted that the metal layer can be tungsten or an alloy.
[0048] Furthermore, the two groups of rotating circles 42 are symmetrically arranged with respect to the annular ring 41 , and a plurality of grooves are arranged on the side of the sub-sheet 43 facing away from the surface material 1 .
[0049] Furthermore, a gap is formed between the rotating circles 42 , and the width of the gap is at least twice the width of the rotating circle 42 .
[0050] Specifically, by changing the original antenna structure and combining it with the special structure of the metal layer, the antenna's heat dissipation capacity can be effectively improved. At the same time, the deposited metal layer can also increase the antenna's strength.
[0051] The present invention also provides a method for preparing an electronic tag, which is used to prepare the above-mentioned electronic tag, comprising the following steps:
[0052] S1: Improve surface material 1, antenna raw material and adhesive;
[0053] S2: placing the antenna raw material on the surface material 1, and adding an adhesive between the antenna raw material and the surface material 1;
[0054] S3: Scanning the antenna raw material by a laser polishing machine to bond the antenna raw material to the surface material 1;
[0055] S4: solder the chip 5 to the antenna 4, and apply a layer of colloid 2 on the same side of the surface material 1 and the antenna 4;
[0056] S5: coating a layer of colloid 2 on one side of the backing paper 3, and pressing the surface material 1 coated with the colloid 2, the surface material 1 coated with the colloid 2 and the antenna 4;
[0057] S6: After die-cutting, an electronic label is obtained.
[0058] Furthermore, a 10-15A metal layer is deposited on one side of the antenna raw material mounting chip 5 , and a plurality of metal teeth are arranged on the outside of the sub-chip 43 .
[0059] Furthermore, the process of scanning the antenna raw material by the laser polishing machine in S3 is as follows:
[0060] S301: placing an adhesive on the surface material 1, and then placing the antenna raw material and the adhesive correspondingly;
[0061] S302: adjusting the parameters of the laser polishing machine, first scanning the sub-sheets 43 on both sides of the antenna raw material, so that the thickness of the metal layer deposited on the surface of the sub-sheet 43 becomes half of the original thickness after one scan, and then scanning out a plurality of parallel tooth marks;
[0062] S303: Scan the annular ring 41 and the rotating ring 42 in sequence to reduce the thickness of the metal layer deposited outside the annular ring 41 and the rotating ring 42 to one third of the original thickness.
[0063] Specifically, the antenna preparation process of this embodiment combines the antenna and the surface material 1 together and solidifies the adhesive with the temperature generated by laser scanning, which can effectively improve the production efficiency and positioning accuracy of the antenna. At the same time, after laser polishing, the original antenna surface becomes clean, thereby improving the bonding effect with the colloid.
[0064] Among them, the two groups of sub-sheets 43 are polished first, and the heat generated by polishing is used to bond the two groups of sub-sheets 43 to the surface material 1. At the same time, the two groups of sub-sheets 43 are laser polished for the second time, which effectively ensures the curing of the adhesive, completes the positioning of the antenna 4, and further ensures the polishing accuracy.
[0065] It should be noted that there is no adhesive between the rotating ring 42 and the surface material 1 , and the rotating ring 42 and the surface material 1 are pressed together so that the colloid 2 enters the gap between the rotating ring 42 and the surface material 1 .
[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
