Description

RFID radio frequency chip

Technical Field

The utility model relates to the technical field of radio frequency chips, in particular to an RFID radio frequency chip.

Background

RFID radio frequency chips are physical carriers of Electronic Product Codes (EPC), attached to trackable items, and identify and read and write them, and can identify specific targets and read and write related data by radio signals without establishing mechanical or optical contact between the identification system and the specific targets.

The RFID radio frequency chip used at present lacks good protection shielding assembly for the chip obtains bad good information protection during not using, and lacks the part of pasting, is unfavorable for personnel to paste according to the user demand at will. To this end, we propose an RFID radio frequency chip.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims to provide an RFID radio frequency chip which can effectively solve the problems in the background technology.

In order to achieve the purpose, the utility model adopts the technical scheme that:

the RFID radio frequency chip comprises a substrate, an RFID chip, a shielding film, a frame type double-sided adhesive tape and an acrylic plate, wherein the substrate comprises a hard PVC film and a PVC membrane, and the RFID chip is positioned between the PVC film and the PVC membrane.

Furthermore, the outer side of the PVC membrane of the substrate is glued and connected with a frame-shaped double-faced adhesive tape.

Furthermore, a shielding film is pasted on the frame type double-sided adhesive tape.

Further, the shielding film comprises a PVC dustproof film and a red copper sheet.

Further, an acrylic plate is arranged on the back of the substrate in an adhesive mode.

Compared with the prior art, the utility model has the following beneficial effects:

1. personnel pass through the subassembly that substrate, RFID chip, shielding film, frame type double faced adhesive tape pasted and ya keli board is constituteed, realize providing RFID radio frequency chip for personnel, and the shielding film that pastes through frame type double faced adhesive tape is used for pasting to frame type double faced adhesive tape and covers dustproof, and when whole RFID radio frequency chip need paste the use to the foreign object, personnel torn the shielding film that frame type double faced adhesive tape pasted, makes the substrate can paste the foreign object.

2. Through the setting of red copper sheet, when whole RFID radio frequency chip does not use, provide the shielding layer to RFID radio frequency chip both sides, make external equipment can't discern the ya keli board to the RFID chip and can help personnel to write the mark through the marker pen, make the coming and going personnel can understand directly perceivedly, whole RFID radio frequency chip is stable in utilization and safe, it possesses good shielding protective component, shield the RFID chip during not using, in order to avoid outside reading equipment to get at will and read, and good gluing mechanism is provided, help personnel according to the user demand, paste the connection with the chip to external equipment, greatly increased use's flexibility, higher practicality has.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

As shown in fig. 1-5, an RFID radio frequency chip includes a substrate 1, an RFID chip 2, a shielding film 6, a frame-shaped double-sided adhesive tape 5, and an acrylic plate 9, where the substrate 1 includes a rigid PVC base sheet 3 and a PVC membrane 4, the RFID chip 2 is located between the PVC base sheet 3 and the PVC membrane 4, and the PVC base sheet 3 and the PVC membrane 4 are connected by vacuum-pumping and hot-pressing.

Wherein, the outer side of the PVC membrane 4 of the substrate 1 is provided with a frame-shaped double-sided adhesive tape 5 in an adhesive way; the frame-shaped double-sided adhesive tape 5 is convenient for personnel to stick the substrate 1 to foreign matters.

Wherein, a shielding film 6 is pasted on the frame type double-sided adhesive tape 5; the shielding film 6 on the frame-shaped double-sided adhesive tape 5 is used for pasting and covering the frame-shaped double-sided adhesive tape 5 for dust prevention, and when the whole RFID radio frequency chip needs to paste and use a foreign object, a person tears down the shielding film 6 on the frame-shaped double-sided adhesive tape 5, so that the substrate 1 can paste the foreign object.

The shielding film 6 comprises a PVC dustproof film 7 and a red copper sheet 8, the thickness of the red copper sheet 8 is 0.2cm, and the PVC dustproof film 7 is connected with the red copper sheet 8 in an adhesive manner; through the setting of red copper sheet 8, when whole RFID radio frequency chip did not use, provide the shielding layer to RFID radio frequency chip both sides, make external equipment unable discernment RFID chip 2.

The back of the substrate 1 is glued with an acrylic plate 9, a shielding film 6 is adhered to the acrylic plate 9 inside the substrate 1, and the acrylic plate 9 is made of an opaque acrylic material; the acrylic plate 9 can help people to write and mark through a marking pen, so that the coming and going people can visually know.

It should be noted that the utility model is an RFID radio frequency chip, when working, personnel attach the required data to the RFID chip 2 by using the electromagnetic field which is adjusted to the radio frequency, when using, personnel carry out hot pressing protection to the two sides of the RFID chip 2 through the substrate 1 which is composed of the hard PVC bottom sheet 3 and the PVC membrane 4, the shielding film 6 on the frame-shaped double-sided adhesive tape 5 is used for pasting and dust prevention of the frame-shaped double-sided adhesive tape 5, when the whole RFID radio frequency chip needs to be pasted to a foreign object, a person tears off the shielding film 6 on the frame-shaped double-sided adhesive tape 5 to enable the substrate 1 to be capable of pasting the foreign object, and through the arrangement of the red copper sheet 8, when the whole RFID radio frequency chip is not used, provide the shielding layer to RFID radio frequency chip both sides, make external equipment can't discern the ya keli board 9 to RFID chip 2 and can help personnel to write the mark through the marker pen, make the personnel of coming and going can understand directly perceivedly.
