Description

Technical Field

[0001] The present invention relates to a structure improvement technology of an IPC classification G09F display label or nameplate and a G06K recording carrier-related self-adhesive logistics label, in particular to an ultra-thin portable multi-layer logistics electronic label. Background Art

[0002] At present, the widely used detachable electronic tags are mainly composed of three layers, namely the base paper, the middle layer and the surface material. The middle layer or the support can be a 20-80um film, 30-100gsm coated paper, glassine or other paper. The three layers of materials are glued and compounded and then die-cut to form a detachable electronic logistics label.

[0003] In addition, the application of electronic tag technology in the logistics field is also developing rapidly. Electronic tags are also called radio frequency tags, transponders, and data carriers; electronic tags are the carriers of RFID technology, and the operating frequencies include 125KHZ, 13.56MHz, 915MHz, 2.45GHz, and 5.8GHz. The most basic electronic tag system consists of three parts: Tag: It consists of coupling elements and chips. Each tag has a unique electronic code. High-capacity electronic tags have user-writable storage space and are attached to objects to identify target objects; Reader: A device that reads tag information and can be designed as handheld or fixed; Antenna: It transmits radio frequency signals between tags and readers. The readers that usually match electronic tags are also called readout devices, scanners, readers, communicators, and readers. In addition to the readout function, readers may also have the function of wirelessly rewriting data. The spatial contactless coupling of radio frequency signals between electronic tags and readers is realized through coupling elements; in the coupling channel, energy transfer and data exchange are realized according to the timing relationship.

[0004] There are few publicly available technical documents on this machine.

[0005] Chinese patent application 201810281556.0 filed by Shanghai Jinlonghao Printing Co., Ltd. provides a BOPP portable logistics label and a production process thereof, wherein the logistics label comprises a customer label and a stub label, and the logistics label comprises, from top to bottom, a thin thermal paper, a polyacrylic acid glue layer, BOPP, a hot-melt pressure-sensitive adhesive layer, a silicone oil layer and a glassine base paper; during production, silicone oil, hot-melt pressure-sensitive adhesive, composite BOPP, polyacrylic acid glue and composite thermal paper are applied to the glassine base paper through a silicon coating device.

[0006] Chinese patent application 201821381142.7 filed by Shanghai Hongtao Paper Products Co., Ltd. discloses a high and low temperature resistant logistics RFID electronic tag, including a surface material, an electronic chip layer and a base material that are compositely formed from top to bottom. The surface material is made of 0.072mm thick self-adhesive coated paper or 0.05mm thick PET film or 0.05mm thick PI film; the electronic chip layer is composed of an RFID chip and an antenna layer, and the RFID chip is hot-pressed on the upper surface of the antenna layer by glue; the antenna layer uses an aluminum foil etched antenna; the base material is glassine paper; the electronic chip layer is laminated on the upper surface of the base material through a glue layer; the surface material is laminated on the upper surface of the electronic chip layer; the glue layer uses permanent acrylic glue. The high and low temperature resistant logistics RFID electronic tag of the present invention can be used normally at temperatures between -60°C and 300°C, ensuring the adhesion function of the RFID tag and realizing the visual management of assets in the logistics process.

[0007] From a more detailed structural point of view, the detachable electronic tag structure actually has as many as six to eight layers. The large number of structural layers and the complexity lead to complex production processes, cumbersome processing, and low production efficiency. On the other hand, from the perspective of resource consumption, as well as manufacturing and application cost accounting, the middle layer is a full-width lamination, or the middle layer uses a full-width film or paper, which consumes more ecological and environmental resources and has high economic costs. From the perspective of the final application, the overall label is thick, has high stiffness, poor compliance, and is not conducive to portability. Summary of the invention

[0026] The principle of the present invention is that after the RFID module 8 embedded in the back of the label printing paper 2 enters the magnetic field, it receives the radio frequency signal sent by the reader, and uses the energy obtained by the induced current to send out the product information stored in the chip, namely PassiveTag, passive tag or passive tag, or actively send a signal of a certain frequency, namely ActiveTag, active tag or active tag; after the reader reads and decodes the information, it is sent to the central information system for relevant data processing. The RFID module 8 has a read / write unit, a memory, an electronic transceiver and an antenna structure. The reader or reading device that cooperates with it sends electromagnetic pulses through the antenna, and the transceiver receives these pulses and sends the stored information to the reader as a response. In fact, this is a non-contact reading, writing or deleting process of the data in the memory of the RFID module 8.

[0027] The present invention is also suitable for harsh logistics environments and is insensitive to moisture, dirt and mechanical impact. In addition, it also adapts to the development trend of artificial intelligence automatic logistics, that is, the importance of labeling visual concise information gives way to the electronic storage data information of the RFID module 8.
