Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of super high frequency radio frequency antenna, specifically, it relates to a copper wire sewing thread antenna super high frequency laundry label. BACKGROUND

[0002] Laundry labels have wide application in laundry shops, high-grade clothes, school uniforms, special clothes, clothes production management, product tracking, warehouse inventory and the like. However, the existing various laundry labels have different defects.

[0003] 1. Defects of carbon fiber super high frequency laundry label

[0004] Traditional laundry labels mostly adopt carbon fiber to make antennas, which can resist washing, folding, pressing and high temperature, and meet the technical requirements of the laundry industry. However, the traditional carbon fiber antenna laundry label has various defects, which affects the popularization and application in the laundry industry.

[0005] (1) Since the carbon fiber has low conductivity, multiple carbon fibers need to be combined to make an antenna, and the carbon fiber has high price and large consumption, which leads to extremely high cost of laundry label materials.

[0006] (2) The process of making a radio frequency antenna from carbon fiber is complex. First, multiple carbon fibers are wound into a sinusoidal wave shape, and then sewing thread is used to fix it. The production efficiency is low, and the manufacturing cost is high.

[0007] (3) The radio frequency resonant cavity of the carbon fiber super high frequency laundry label is a double-sided PCB board structure. The upper and lower copper foils of the PCB board are chemically etched to form two independent small antenna rings, and then the two small antenna rings are connected in series through the plated holes on the upper and lower layers of the PCB board to form a double-coil resonant cavity. Then, the chip is encapsulated to form a series resonant cavity, and then the epoxy resin is encapsulated to form an integrated PCB double-coil radio frequency resonant cavity assembly. The thickness of the PCB double-coil radio frequency resonant cavity assembly is close to 2mm.

[0008] Obviously, the process of the carbon fiber super high frequency laundry label is complex, the appearance flatness is poor, and the manufacturing cost is high.

[0009] (4) The laundry industry is a low-profit industry, and the carbon fiber antenna laundry label has high price, which becomes the biggest resistance to the popularization and application of radio frequency technology in the laundry industry and linen industry. Therefore, many laundry enterprises and linen enterprises have not used radio frequency technology.

[0010] 2. Defects of silica gel super high frequency laundry label

[0011] The silicon gel super high frequency laundry tag adopts PET aluminum foil chemical etching process to manufacture the antenna, and the cost of the antenna is only 1 / 8 of the cost of the carbon fiber antenna, but the cost of the silicon gel packaging into the tag is also high, the total cost is similar to the cost of the carbon fiber super high frequency laundry tag, and the radio frequency performance is unstable, so the super high frequency laundry tag cannot be popularized and applied.

[0012] 3. Defects of sewing installation of the carbon fiber antenna radio frequency laundry tag

[0013] Currently, the radio frequency laundry tag is sewn on the garment by using the sewing installation process, which is time-consuming and brings a lot of workload to the garment management and laundry factory.

[0014] 4. Defects of the adhesive installation process

[0015] In the adhesive installation process, the hot melt adhesive is pre-coated on the bottom surface of the cloth radio frequency laundry tag, and then the radio frequency laundry tag with the pre-coated hot melt adhesive is pressed on the garment by using a hot press head or a high temperature electric iron, after the hot melt adhesive is melted, the power is turned off, when the temperature of the hot melt adhesive decreases, the electric iron is removed, and the radio frequency laundry tag is pasted and fixed on the garment. The defect is that the operation requires strictness, otherwise the service life stability and consistency of the laundry tag and the garment are poor, which brings trouble to the laundry operation process.

[0016] Therefore, the garment industry needs a super high frequency laundry tag which is washable, foldable, high temperature resistant, low in price, and easy and reliable to install on the garment. Content of the utility model

[0048] The utility model will be further described below in combination with the drawings and embodiments:

[0049] As Figs. 1a to 2b shown, the utility model discloses a copper wire sewing thread antenna ultra-high frequency laundry label to overcome the low service life of the existing laundry label, unstable radio frequency performance, high raw material and processing cost, great processing difficulty, time and labor consuming and inconvenient management and other defects.

[0050] The copper wire sewing thread antenna ultra-high frequency laundry label comprises a label cloth, a double-loop radio frequency resonant cavity assembly 10, a copper wire sewing thread sewn ultra-high frequency antenna 50 and a common sewing thread suture 40. Therefore, the copper wire sewing thread antenna ultra-high frequency laundry label has the characteristics of small size, thin thickness, light weight and easy installation.

[0051] 1, label cloth

[0052] The label cloth comprises a laundry label bottom layer high-temperature-resistant cloth 20 and a laundry label upper layer high-temperature-resistant cloth 30.

[0053] The laundry label bottom layer high-temperature-resistant cloth 20 and the laundry label upper layer high-temperature-resistant cloth 30 are both made of washable and high-temperature-resistant materials. After the double-loop radio frequency resonant cavity assembly 10 is installed on the laundry label bottom layer high-temperature-resistant cloth 20, the laundry label upper layer high-temperature-resistant cloth 20 can be compounded.

[0054] 2, double-loop radio frequency resonant cavity assembly

[0055] The double-loop radio frequency resonant cavity assembly 10 is installed between the laundry label bottom layer high-temperature-resistant cloth 20 and the laundry label upper layer high-temperature-resistant cloth 30. The double-loop radio frequency resonant cavity assembly 10 comprises a PET bottom film 17, a micro double-loop radio frequency resonant cavity, an ultra-high frequency chip 13 and a solid high-temperature resin.

[0058] (2) Micro double-loop radio frequency resonant cavity and ultra-high frequency chip

[0059] The micro double-loop radio frequency resonant cavity comprises two micro coils, a chip packaging site and a short circuit line 13-1. The two micro coils, the chip packaging site and the short circuit line 13-1 are all formed by etching an aluminum foil.

[0060] The short circuit line 13-1 connects two micro coils in series and passes through the chip packaging position. Specifically, the two micro coils are the double-coil type radio frequency resonant cavity outer ring aluminum foil 11 and the double-coil type radio frequency resonant cavity inner ring aluminum foil 12. The short circuit line 13-1 connects one end point of the double-coil type radio frequency resonant cavity outer ring aluminum foil 11 and one end point of the double-coil type radio frequency resonant cavity inner ring aluminum foil 12. The other end point of the double-coil type radio frequency resonant cavity outer ring aluminum foil 11 and the other end point of the double-coil type radio frequency resonant cavity inner ring aluminum foil 12 are the packaging feet of the chip and the resonant cavity connection position 13-2.
