Description

UHF RFID grass label with enhanced washability Technical Field The utility model relates to the technical field of electronic tags, in particular to a UHF RFID linen tag with enhanced washability. Background Linen is commonly referred to by hotels, guesthouses, hospitals, etc. as towels, sheets, quilts, pillowcases, etc., and "linen labels" refer to labels used to identify linen. The UHF RFID technology is an ultrahigh frequency radio frequency identification technology, and has the characteristics of long identification distance, high data transmission rate, capability of identifying a plurality of tags at the same time and the like, wherein the working frequency range of the UHF RFID technology is in an ultrahigh frequency range. However, in the prior art, structural damage such as near field module displacement and material deformation exists in the repeated washing process of the UHF RFID linen label in a relatively complex washing environment (such as high temperature, high pressure and strong chemical washing), so that the structural stability and the reading effectiveness of the UHF RFID linen label are affected. Based on the reasons, the UHF RFID linen label with enhanced washability is designed, and the problems of structural strength and stability in a complex washing environment are realized by improving the whole material of the linen label and structurally adjusting the whole material of the linen label, so that the normal and repeated use of the UHF RFID linen label is ensured. Disclosure of utility model The utility model aims to overcome the defects of the prior art, and provides the UHF RFID linen label with enhanced washability, and the problems of structural strength and stability in a complex washing environment are realized by improving the overall material of the linen label and structurally adjusting the overall material of the linen label, so that the normal and repeated use of the UHF RFID linen label is ensured. In order to achieve the above purpose, the UHF RFID grass-laying label with enhanced washability comprises a substrate, wherein a near field module is arranged on the substrate, far field antennas are arranged on two sides of the near field module, the near field module is arranged in a circular coupling area formed in the middle of the far field antennas and is in non-contact with the near field module, the near field module is completely covered by a glue dripping layer, the thickness of the glue dripping layer is 1.5 mm-2 mm, and the coverage area of the glue dripping layer is in the circular coupling area formed in the middle of the far field antennas. The far-field antennas are symmetrically distributed on two sides of the near-field module. The substrate is a cloth-based substrate. The adhesive dropping layer is formed by adhesive dropping with the peel strength more than or equal to 8N/cm and the temperature resistant range of-40 ℃ to 190 ℃. The glue dropping layer is formed by hot melt glue dropping modified polyurethane glue dropping. The near field module includes a UHF chip. Compared with the prior art, the utility model has the following beneficial effects: According to the utility model, the flexible material is used as the base material, and the far-field antenna is firmly embedded into the base material through the sewing jacquard and hot pressing process, so that the position and shape of the far-field antenna are kept fixed. Meanwhile, the near-field module is fixed in the middle of the circle of the far-field antenna by adopting the dispensing precision of 0.2mm, a certain thickness of adhesive dripping layer is formed by using the adhesive dripping material with high peel strength and temperature resistance range, so that the near-field module is completely covered, the invasion of water vapor and chemical substances is isolated, the position of the near-field module on a substrate is protected from being stable, the performance is stable, and the requirement of repeated washing under a complex environment is further met.
