Detailed Description
In order to more clearly illustrate the present invention, preferred embodiments are described in detail below with reference to the accompanying drawings. Referring to fig. 1 to 4, a tag 100 and a reading device 200 according to a preferred embodiment of the present invention are shown.
The tag 100 has a tag body 10, a connecting element, and a wireless radio frequency identification element 30. The tag body 10 has a first surface 10a and a second surface 10b opposite to each other, and a through hole 10c. Wherein the through hole 10c penetrates the first surface 10a and the second surface 10b.
The connecting element is a rivet 20 made of metal for connecting the tag body 10 and the RFID element 30. The rivet 20 has a head and a body connected to the head, and the body has an outer diameter smaller than the outer diameter of the head. After the body of the rivet 20 is inserted through the through hole 10c from the first surface 10a, the head of the rivet 20 is abutted against the first surface 10a of the tag body 10, and the portion of the body exposed outside the through hole 10c is pressed by a pressing device (not shown), so that the body is radially expanded and deformed to be abutted against the second surface 10b of the tag body 10. The portions of the head and body that are compressively deformed constitute the first and second enlarged portions 22 and 24, respectively, in this embodiment, while the portions of the body that are located in the perforations 10c and that are not compressively deformed constitute the neck portions 26 in this embodiment. Wherein the top edge of the first enlarged portion 22 is concavely formed with a receiving hole 22a.
The rfid device 30 includes a main body 32 and an electronic component 34 disposed in the main body 32. The main body 32 is inserted into the accommodating hole 22a, and has a maximum width of not more than 10 mm and a maximum height of not more than 10 mm. The body 32 has a top section 321 and a bottom section 322 opposite each other, and a middle section 323 connecting the top section 321 and the bottom section 322. The outer diameter of the main body 32 gradually expands from the free end surface of the top section 321 to the free end surface of the bottom section 322 toward the middle section 323. In this way, when the bottom section 322 of the main body 32 faces the accommodating hole 22a and is plugged into the accommodating hole 22a, the middle section 323 of the main body 32 is attached to the wall of the accommodating hole 22a, so that the main body 32 is stably located in the accommodating hole 22a and is not easy to fall off. The body 32 in this embodiment is made of plastic including, but not limited to, nylon and engineering plastic.
The electronic component 34 is located in the top section 321 of the main body 32, and when the near field communication chip of the electronic component 34 is triggered, the information stored in the chip can be transmitted, or the signal can be received and stored in the chip.
The reading device 200 has a housing 40, a reading head 50 and a circuit board 60. The housing 40 includes a base 42 and a shell 44. The housing 44 is coupled to the base 42 and has a receiving slot 45. As shown in fig. 3 and 4, the accommodating groove 45 is formed by recessing downwards from the upper surface of the housing 44, and the groove shape of the accommodating groove 45 is designed according to the partial outline shape of the tag 100, and the accommodating groove 45 has a main positioning groove section 452, a first auxiliary positioning groove section 454 and a second auxiliary positioning groove section 456. The main detent section 452 defines a long axis A1 and a short axis A2. The main positioning groove section 452 has two opposite long groove walls 452a in the long axial direction A1, two opposite short groove walls 452b in the short axial direction A2, and each long groove wall 452a is adjacent to each short groove wall 452 b. The first auxiliary positioning groove section 454 and the second auxiliary positioning groove section 456 are respectively positioned on the two long groove walls 452a and are communicated with the main positioning groove section 452.
Wherein the channel of the main detent section 452 corresponds to at least a partial contour shape of the swing ticket body 10; the grooves of the first auxiliary positioning groove section 454 correspond to at least a partial contour of the first enlarged portion 22, and the grooves of the second auxiliary positioning groove section 456 correspond to at least a partial contour of the second enlarged portion 24.
The reading head 50 is disposed on a supporting wall 422 inside the housing 40, and the transmitting end of the reading head 50 faces the sidewall of the first auxiliary positioning slot 454. The circuit board 60 is disposed on the inner bottom surface of the base 42, and electrically connects the read head 50 and an external computer system (not shown). When the reading head 50 is in signal connection with the RFID element 30, the external computer system and the RFID element 30 can exchange data for subsequent application.
The reading device 200 further comprises a display lamp 70. The display lamp 70 is disposed on the housing 40 and partially exposed to the outside, and the display lamp 70 is electrically connected to the circuit board 60. When the reading head 50 is in signal connection with the RFID device 30, the display lamp 70 will be turned on to help identify whether the RFID device 30 is in signal connection with the reading head 50.
With continued reference to fig. 4, when the tag 100 is inserted into the accommodating groove 45, the tag body 10 is located in the main positioning groove section 452, the lower edge of the first enlarged portion 22 abuts against the groove bottom of the first auxiliary positioning groove section 454, and the lower edge of the second enlarged portion 24 abuts against the second auxiliary positioning groove section 456, so that the rfid 30 will correspond to the signaling end point of the read head 50, so that the read head 50 and the rfid 30 can be accurately connected in a signal manner, thereby ensuring the stability of the message exchange process. Therefore, the user only needs to insert the tag 100 into the accommodating groove 45 of the reading device 200 to complete positioning, and the dedicated data page of the rfid 30 is established in the external computer system in the state that the reading head 50 is connected with the rfid 30 by signals, so that the initial database establishment process of the rfid is more convenient.
It should be noted that the tag 100 is not limited to being positioned against the slot wall of the first auxiliary positioning slot section 454 and the slot wall of the second auxiliary positioning slot section 456. As shown in fig. 5, in other practical applications, the tag body 10 can be abutted against the bottom of the main positioning slot 452 to achieve the positioning effect, so that the rfid device 30 corresponds to the transmitting end of the reader 50, but is not limited thereto.
The above description is only of the preferred embodiments of the present invention, and all equivalent changes in the specification and claims should be construed to be included in the scope of the present invention.
