BACKGROUND OF THE INVENTION The market demand for RFID tags in China has formed a scale and the demand is increasing. The RFID tag antenna is a key technology for RFID tags. Radio frequency identification tag antenna design and manufacturing technology is also becoming more and more diverse. Not only etching/stamping antennas, printed antennas and wound antennas, new antenna fabrication methods are emerging. The hot stamping label of the antenna obtained by the hot stamping and cold foiling process is a new form, but the antenna surface is not wear-resistant, the chip part is prominent, and the surface needs to be re-applied with a protective layer, which is currently only applied to Paper use.

This form of construction, due to the presence of the release layer (3), is a typical non-durable label. Plastic products are a durable product, how to use the matching RFID tags, the label form mentioned above is not suitable. In order to solve the problem that the RFID tag can be firmly attached to the plastic product, the label can be reused for a long time and the label is not easily dropped. It is the long-term uninterrupted innovation of many people. The common feature of [Radio Frequency Identification In-Mold Forming Label] with application number 200410078355. 9 and [Radio Frequency Identification In-Mold Forming Method and Product] with application number 200710086104. 9 is to make the same base as plastic products. The RFID tag shape is embedded in a plastic mold and molded into a plastic to form an article. This method solves the problem that the labels in plastic products are not durable. But how to make it: First, form the "first molding die", find the appropriate "substrate" and install the "radio frequency identification tag" to make the embedded substrate and RFID tag. Into the shape, a robot inserts the embedded shape of the RFID tag into a "second molding die" and becomes a new one by injection molding, extrusion molding, hollow molding, and the like.

"plastic products". Achieving radio frequency identification tags in plastic products can be "prevented from being improperly damaged" into a durable product. Among them, although the manufacturing process of RFID tags is not innovative, the embedded shape of RFID tags is an innovation. Among them, the material of the selected substrate is similar to that of the plastic material, and can achieve "similar compatibility" with the molten plastic under high temperature conditions. For the purpose of "similar compatibility", the application number is 200880101767. The patented label for [radio frequency identification tags, molded products and related methods] uses a splicing method to obtain a substrate for RFID tags of the same material as plastic. The above-mentioned process for fabricating the substrate of the RFID tag is complicated, and even the method of the slit method adopted for the substrate of the [RF identification tag, molded product and related method] of the application number 200880101767. 6 has high mechanical value. Significantly increased costs. In spite of this, it is necessary to embed the RFID tag in the plastic part to ensure that the bonding strength with the plastic product forms a whole. The radio frequency identification tag contained in the plastic product is obtained, and various information can be tracked, and the information in the label can be read by the instrument, and like the plastic product, it can be used repeatedly and has excellent durability. This kind of embedding method must pre-produce the embedded shape of the RFID tag, which requires labor and materials. At the same time, the embedded shape of the RFID tag must be placed into the injection mold by the robot during the injection molding, which prolongs the molding time of the plastic and costs a high cost. . The widespread use of RFID tags in plastic products is limited.

The above process steps can also form a thermally stable coating layer or a metal layer of the antenna portion on the dielectric layer on which the oxide-protected hologram pattern surface is plated. The printing of the ink graphic with the graphic RFID tag can print other thermal inks, including the electric eye recognition black mark, while printing the heat stable layer or the transparent pigment heat stable coating ink.

The process of printing the ink on the surface of the antenna in the RFID-containing antenna layer of the present invention may also be: printing an insulating ink, a conductive ink and/or an ordinary ink on the surface of the antenna metal layer, on the surface of the antenna metal layer The printed ink portion may be the same size as the antenna metal layer portion, or may be larger than the antenna metal layer portion and covered to the surface of the protective layer.

The invention discloses a method for implanting a plastic article with a graphic RFID tag in a roll, which is under the action of the heat and the injection pressure of the molten plastic molding process between 120-300 ° C in the mold cavity of the injection molding machine, including the graphic RF The adhesive tape of the identification label is adhered to the plastic article by heat, and is gradually contained in the plastic molded article by the plastic, and is separated from the process of peeling off the PET base film layer.

The invention comprises a graphic radio frequency identification tag, and carries one-by-one graphic identification tag. The RFID-containing label prepared by the invention is sent to the injection mold cavity one by one through the film feeding machine and the injection molding operation procedure of the injection molding machine, and the heat and pressure of the molten plastic when the injection molding machine is used for injection molding. It is easy to implant the RFID tag with RFID on the surface of the plastic product, which does not take up the injection time and saves human resources. It saves the trouble of inserting the RFID tag into a single shape by the original patent, and saves the trouble of the original patent selection of the same material as the plastic material. The surface resin of the protective layer after the plastic product is implanted, especially the UV resin layer, not only protects the surface of the plastic substrate, but also protects the radio frequency identification hologram label embedded in the plastic product. In this way, the graphic RFID tag embedded in the plastic product can be used repeatedly like the plastic product, and can be used repeatedly without falling off, thereby achieving the management of the radio frequency identification function of the plastic product and the appearance of the label and the plastic product. Anti-counterfeiting and decorative, durability. The invention will be further described with reference to the accompanying drawings. In order to achieve the wide application of the RFID tag in the plastic article, the RFID-containing RFID tag in the implantable plastic product of the present invention is a laser embossing holography process, a printing process, and vacuum plating. Process, washing process, injection molding process, combined with RFID tag function, with a release PET base film as a carrier layer, a protective layer, containing hologram At least one of the radio frequency identification antenna layer and the radio frequency identification chip layer, the thermal stability layer, and the adhesive layer of the graphic image, the ink graphic, and the metal image become a multi-structured radio frequency identification tag and are wound into a roll. The most basic structural layer of the cross-section of the RFID tag with the pattern text is shown in Figure 1. The antenna and the image in the RFID-containing antenna layer are adhered to the protective layer, wherein the pattern characters are at least one of a hologram pattern, an ink graphic, and a metal graphic.

The invention relates to a method for manufacturing a graphic RFID tag in an implantable plastic article, and selecting a PET base having a thickness of 20-60 μππ on the surface and having a release force suitable for implanting the RFID tag of the present invention into a plastic product. Membrane layer. For this reason, it is the easiest way to select a surface layer of the protective coating layer that is larger than the surface tension of the surface layer of the PET-based film. The surface tension of the surface layer of the PET-free film layer without surface treatment is 40 mN / m or less. Therefore, if the surface tension of the protective coating layer is selected to be larger than the tension of the surface layer of the PET film which is not surface-treated, the planting can be achieved under certain conditions. The invention of the present invention in the process of entering a plastic article can be used for the purpose of separating the PET base film layer. However, not all selected protective layers meet the above requirements. For this reason, materials such as wax, silicone oil, and resin are pre-coated on the surface of the PET base film layer to change the surface tension and increase the release force to accommodate more protective layer materials. If most of the thermosetting resin protective layer, UV resin protective layer and PET base film constitute the RFID-containing label of the present invention, the release force required for the process of implanting the plastic product needs to be in the PET base film. A material such as wax, silicone oil, or resin is preliminarily coated on the surface of the layer.

The method for manufacturing the graphic RFID tag in the implantable plastic article of the invention adopts a PET base film with release force, and a coating layer is used thereon to obtain a protective layer, and the protective layer is printed on the protective layer. The vacuum plating process, the water washing process, etc., forming the antenna thermal stabilization layer and the antenna metal layer are a feature of the present invention, and the process steps are as follows: making an electro-optical identification mark pattern gravure plate roll, and making a part other than the shape of the antenna Gravure plate roll, making a gravure roll for the antenna part. The gravure printing process is selected, and the electric eye recognition mark ink, the water-soluble ink except the antenna pattern, and the heat stable paint of the antenna part are gravure printed on the protective layer. Since the water-soluble ink retains the portion of the antenna during printing, the heat-stabilized coating of the antenna portion printed on the back is limited by the antenna portion to be retained, and the excess heat-stable coating can only cover the water-soluble ink layer. In actual production, taking into account the error of the printing machine set, the size of the antenna pattern part of the heat-stabilized coating should be larger than the size of the antenna pattern part that has been taken. 0.1 mm to ensure the antenna thermal stable coating layer after washing. The portion overlaps with the metal layer portion, that is, the coverage of the heat-stable coating layer is not lost in the antenna portion. as shown in picture 2. Among them, 12-20 is the water-washing ink layer. In fact, the antenna part of the 12-20 water-washing ink is the hot-stabilized coating layer of the antenna, and 12-25 is the electric eye calibration marking mark during injection molding. After printing the water-washed ink and the heat-stable paint, the roll of the PET film is placed in a vacuum plating machine and plated with a metal layer. After the vacuum metallization layer, the heat-stabilized coating attached to the washing ink and the metal particles on the vacuum plating are evenly distributed on the surface of the dry-solid washing ink, which is blocked by the titanium dioxide, silica, and kaolin particles contained in the washing ink. The heat-stable coating, the metal particles attached to the surface layer of the water-soluble ink, and the protective layer are not adhered. Thus, the water-washing ink dissolves in the aqueous solution and carries away the heat-stable coating material and metal particles attached thereto, leaving only the heat-stable layer and the metal layer which are tightly adhered to the antenna portion above the protective layer. As shown in Figure 3, 12-11 is the antenna metal pattern after washing, 12-12 is the non-antenna metal image, and 12-25 is the electric eye identification mark. In actual production, the antenna metal layer of 12-11 is also included. The same thermal stability layer as the antenna. The metal layer containing the radio frequency identification antenna can also form a thermal stable coating layer and a metal layer of the antenna portion on the surface of the hologram pattern on the surface of the protective layer after the oxide dielectric protective layer is plated. The oxide dielectric layer on the vacuum plating may be a metal oxide such as aluminum oxide or a non-metal oxide such as silicon dioxide or the like. As shown in Figures 7, 8.

As seen in Figure 3, the formation of a metal graphic containing a radio frequency identification tag can form a metal graphic of 12-12 while forming the antenna metal layer 12-11. The thermal stability coating printed on the antenna part of the reservation is a high transparent coating layer, which ensures that the metal layer on the vacuum plating maintains the high transparent brightness of the antenna metal layer under high temperature injection molding conditions. High adhesion to the metal layer of the antenna; high transparent coating layer, also has good adhesion protection on the surface of the hologram pattern or the dielectric layer without degrading the display effect of the hologram; high transparent coating layer, adding appropriate amount of transparency The pigment, as a clear dye coating ink for the metal layer of the antenna portion, adds metallic color to the metal antenna. The thermal stability layer also has the injection pressure and heat to withstand the molten plastic, and protects the stability of the RF identification chip and the antenna. Therefore, it is also used as a heat stable layer that must be applied before the adhesion layer is applied. The thermal stability layer of 1 to 15 ensures the firmness of the RF identification chip and the metal antenna. The heat stable layer having the above characteristics is selected from a material mainly composed of a thermosetting acrylic resin, an alkyd resin, a polyester resin and an aliphatic curing agent. When the heat stabilizing layer is selected as the intermediate layer between the protective layer and the antenna metal layer, in order to make the heat stable layer covering the water-soluble ink easy to be carried away by the water-washing ink, the ratio of the curing agent can be appropriately increased. When the protection RF chip is firmly bonded to the antenna, the ratio of the curing agent can be appropriately reduced. The vacuum plating process can be carried out by vacuum evaporation or vacuum sputtering. Art. The density of the metal layer obtained in one time by the vacuum sputtering process is relatively good. The surface of the washed metal layer of the antenna is directly laser-molded to form a hologram antenna, which is a method for obtaining a hologram antenna. As shown in Fig. 4, 12-11 is the antenna metal layer, and 12-41 is the hologram pattern effect surface of the direct laser molding. Obtaining a hologram-patterned metal antenna, it is also possible to adopt a release-resisting PET base film layer on which a protective layer is obtained by a coating printing process, and a full or partial hologram pattern is formed on the surface of the protective layer by a laser molding process. Or forming a hologram pattern between the anti-counterfeiting and the decorative phase, and then adopting a printing process, a water washing process, and a vacuum plating process to form an antenna thermal stability layer and a metal layer, which are displayed under the antenna thermal stability layer, the metal layer and the non-metal layer, The different effects of the hologram pattern are another method of the present invention, and the process is as follows: selecting a gravure printing process, making an gravure printing plate of the electric eye recognition mark pattern, and making a gravure printing plate of a water-soluble ink pattern other than the shape of the antenna, A pattern gravure plate for making metal parts of the antenna. On the protective layer of the existing hologram pattern, the electric eye recognition mark ink is divided and printed, and the water-soluble ink except the antenna pattern is printed on the antenna metal heat stable paint layer coating. Refer to Figure 2

After printing the water-washing ink and the heat-stable coating layer, the rolled PET film was placed in a vacuum plating machine and plated with a metal layer. After the vacuum metallization layer, the heat-stable coating attached to the surface layer of the water-soluble ink and the metal particles on the vacuum evaporation are evenly distributed on the surface of the dry-solid water washing ink, because the washing ink contains titanium dioxide, silica, kaolin particles. The barrier prevents the heat-stable coating, metal particles attached to the water-soluble ink from adhering to the protective layer. In this way, the water-washing ink dissolves in the aqueous solution and carries away the heat-stable coating and metal particles attached thereto, leaving only the antenna thermal stability layer and the metal layer which are tightly adhered to the protective layer. The hologram pattern of the antenna metal layer and the hologram pattern without the antenna metal layer are shown in Fig. 5. The laser embossed hologram pattern on the surface of the protective layer 11 is shown on the surface of the antenna metal layer of 12-11. The hologram pattern of 12-41, the surface of the non-metal layer shows the hologram pattern after 12-42 molding. The laser-molded resin layer is further printed on the surface of the protective layer, and then the hologram pattern is laser-embossed on the surface of the laser-molded resin layer, and then the water-washing ink and the heat-stabilized coating are printed in portions, and the metal layer is vacuum-plated, and the water-washing ink is removed by water washing. And thermally stable coatings, metal particles, forming a holographic pattern antenna, which is another form of obtaining a hologram pattern on the protective layer. As shown in Figure 6. After vacuum-depositing the oxide dielectric layer on the hologram surface of the protective layer or the laser-molded resin layer, the ink-washing ink and the heat-stabilized coating are printed in portions, and the metal layer is vacuum-plated, and the washing ink is removed by water washing. Thermally stable coatings, metal particles, form a holographic pattern antenna, which is another form of obtaining hologram patterns on the protective layer. As shown in Figures 7, 8. In order to protect the presence of the hologram pattern displayed by the non-metal layer, the metal oxide dielectric layer may be vacuum-plated to protect the hologram pattern from being removed or attenuated by the ink or the coating on the subsequent printing. 14 in the figure is a dielectric layer. The hologram pattern of the metal antenna in the RFID-containing antenna layer of the present invention may be a decorative hologram pattern, a special security hologram pattern, or a hologram pattern with decoration and anti-counterfeiting. The hologram pattern effect can be combined with various processes using a laser molding process to obtain various effects.

The process steps of the ink graphic on the printed radio frequency identification antenna layer of the present invention may also take many forms.

On the top of the protective layer, the heat-stabilized coating ink with suitable transparent pigment is printed on the exposed antenna part, and the metallic color effect is obtained under the metal antenna hologram pattern, which not only increases the decorative effect, but also Can strengthen the anti-counterfeiting effect. 12-24 in Figure 8 is a thermal-stabilized coating ink with a suitable clear pigment, which together with a 12-11 metal antenna layer provides a holographic pattern of 12-44 metallic color. The process steps are as follows: A water-soluble ink layer on the surface of the protective layer is printed on the surface of the protective layer, that is, the water-soluble ink is not printed on the antenna portion. A thermally stable coating ink layer with a suitable transparent pigment at the antenna portion is printed on the surface of the protective layer aligned with the removed antenna portion, allowing a layer of thermally stable coating ink with a small amount of transparent pigment to cover the surface layer of the water-soluble ink. The metal layer is vacuum plated. Dissolving and removing the water-soluble ink layer and the heat-stable coating ink layer and the metal layer of the transparent pigment attached to the water-soluble ink in an aqueous solution, obtaining the radio frequency identification antenna metal layer and the transparent color heat-stable coating ink of the same portion of the antenna Floor. The clear color of the transparent color heat stable coating ink can have a wide variety of colors. For example, when the transparent pigment is yellow, under the metal aluminum layer, a golden metallic luster is displayed. and many more.

Printing of ink graphics containing graphic RFID tags can be used to print other thermal inks, including electronic eye recognition black marks, while printing thermal stability or transparent pigment thermal stability coating inks.

The above printing process can be on the surface of the protective layer or on the surface of the oxide dielectric layer.

As shown in Figure 7, the 12-12 non-antenna metal layer and the 12-11 antenna metal layer are set together. 12-41 hologram pattern, 12-22 ink layer set off the 12-43 hologram pattern effect, 12-42 14 oxide medium layer protection against the hologram pattern effect, different.

As shown in Fig. 8, the ink pattern of 12-22 shows the hologram effect of 12-43, and the 12-12 metal pattern layer shows the hologram effect of 12-41's own metal color, 12-11 Together with 12-24, it shows the hologram pattern effect of 12-44 non-self-metal color and the 12-42 hologram pattern displayed by the dielectric layer 14, and each has its own characteristics.

As shown in Figure 12, the 12-23 ink can eliminate the hologram pattern, which is displayed with the 12-43 hologram pattern of the 12-22 ink graphic, 12-12, 12-11 and 15 layers. The 12-41 hologram pattern and the 12-42 hologram pattern that is not set off are also the new graphic appearance effect.

The process of printing the ink image in the RFID-containing antenna of the present invention may also be: when the antenna technology requires, the insulating ink and the conductive ink are printed on the surface of the antenna metal layer, and the image is further completed. Technical requirements for radio frequency identification antennas. The printed portion is also overlaid on the protective or dielectric layer.

The above printed insulating ink is intended to insulate the conductive ink from the reprinted contact with the antenna metal layer. Therefore, the printed portion of the insulating ink should be larger than the conductive ink portion, as shown in FIG. When the conductive ink is required to be connected to the antenna metal layer, the insulating ink should be left blank to meet the technical requirements of the RFID-containing antenna. The cross-sectional structure is shown in Fig. 10. The printing process can be either a screen printing method or a gravure printing method. After printing the insulating ink and the conductive ink, other ink images can be printed on the same layer, as shown in FIG. 11, after the insulating ink 12-21 and the conductive ink 12-13 are printed on the 12-11 metal antenna plan. , then print the label 12-22 ordinary ink or other graphic ink.

In actual production, the position of the hologram pattern, the position of the ink graphic, and the position of the metal graphic, as long as it does not affect the technical requirements of the radio frequency identification antenna, can be formed on the upper and/or below the antenna metal layer according to customer requirements. Hologram pattern, ink graphic, metal graphic. In particular, while making the antenna heat stable layer and the metal layer, the conductive ink is printed, and other non-antenna metal images, hologram patterns, and ink images are produced. There are many forms and they cannot be expressed one by one.

If the antenna metal layer of the present invention fails to reach the thickness of the technical requirements of the radio frequency identification antenna, in order to ensure excellent electrical conductivity, the thickness of the attached metal layer can be increased by slowing down the vacuum plating speed of the PET film. In order to ensure that the electrical conductivity meets the technical requirements of the RFID-containing antenna. After the metal layer is formed for the first time, the metal of the same material as the first layer or the metal of the different material may be vacuum-plated again to increase the thickness of the antenna metal layer and improve the conductive effect. For example, after the vacuum evaporation process, the metal layer can be evaporated. Re-evaporation The same metal material on the first vapor deposition, such as the first vacuum evaporation metal layer is aluminum, and the metal layer on the vapor deposition may also be an aluminum layer, or copper of a different metal material may be used. The effect cross section of the metal layer plated twice is shown in FIG. The metal layer of the vacuum plating may be aluminum, copper or silver. It is preferable that the secondary vapor deposition method of aluminum and the primary vacuum sputtering method of silver and copper can obtain good electrical conductivity. After the completion of the process of the metal antenna layer and the printing process in the RFID-containing antenna, the specific position set by the RFID tag technology is adhered to the RFID chip layer by using a well-known general-purpose chip pasting machine, and the radio frequency identification chip layer is included. The antenna metal layers are identified to form a radio frequency identification antenna. After the completion of the graphic-containing RFID chip and the thermal stability of the protective layer, the adhesive layer is applied, and then the material selection of the adhesive layer is determined by the plastic material. For example, the plastic material is ABS, and the glue used is ABS glue. The label film after the adhesive layer is applied, inspected, cut into small rolls by a slitting process, and then packaged into a product. The method for embedding the RFID tag in the plastic article of the present invention is: The graphic RFID tag carries the heat of the molten plastic molding process and the injection pressure of more than 2kg\cm2 under the pressure of 120-300 ° C in the injection molding cavity of the plastic injection molding machine, followed by the RFID tag The glue is adhered to the plastic product by heat, and the plastic is gradually contained in the plastic molded product, and is separated from the PET base film layer. The inventor has proved that the injection pressure is affected by factors such as the shape of the plastic product, the amount of single injection, and the mechanical characteristics. As long as the injection pressure is greater than 2kg\cm2, the adhesive with the RFID tag can be easily adhered. The plastic product is separated from the PET base film layer.

The specific process steps are as follows: 1. Place a roll of the graphic RFID tag on the plastic injection mold 31, pass through the plastic molding cavity of 33, and place it under the plastic injection mold 32. The film collecting device is as shown in FIG. 2. Through the photoelectric device and mechanical matching, the calibration mark 12-25 is determined and fixed in the cavity, corresponding to the position of the label 20 required for the plastic molded product after injection molding, and the mold is closed, as shown in Fig. 14. 3. Close the mold, injection into 34 plastic materials with a melting temperature of 120-300 ° C, in the plastic molding process, the adhesive in the graphic RFID tag 20 is adhered to 34 plastic products. , the graphic RFID tag is gradually implanted into the plastic product to achieve the desired product structure. As shown in Figure 15. 4. Remove the plastic product containing the graphic RF identification tag 41. As shown in Figure 16.
