Description
Technical Field
The utility model relates to a spool, in particular to a spool with an RFID tag function.
Background
At present, in many industries, metal spool wheels are used, the use quantity is huge, the spool wheels can be reused, and when the spool wheels are used for counting the quantity and managing the entering and exiting of the warehouse, the spool wheels have a relatively troublesome problem. At present, the method is better to count the data by an ultrahigh frequency RFID technology.
It is common practice to attach finished RFID tags to flanges on metal spool. However, this approach has many limitations; firstly, an anti-metal label is needed, and because the anti-metal label needs a certain volume and thickness, the metal spool is usually stacked together in use and transportation, so that the anti-metal label is damaged due to collision or the anti-metal label signal cannot be radiated out due to stacking, and the label cannot be collected by reading equipment.
Therefore, a new spool with RFID tag function is needed.
Disclosure of Invention
In order to solve the defects in the prior art, the utility model aims to provide the spool with the RFID tag function.
In order to achieve the above object, the present utility model adopts the following technical scheme:
the spool with the RFID tag function is characterized in that at least one metal slot is arranged on the wheel body of the spool, and the metal slot is used for lap joint with a pin of an RFID chip and is used as a slot antenna of the RFID chip to receive and transmit wireless signals.
Pins of the RFID chip are respectively overlapped with two sides of the metal seam through metal expansion pins.
The wheel body comprises a shaft column and flange plates arranged at two ends of the shaft column.
Further, the metal seam is arranged on the outer side surface or the inner side surface of the shaft post.
Still further, the metal slit is disposed along an axial direction.
Further, the metal seam is arranged on the outer side surface or the inner side surface of the flange plate.
Still further, the inner side surface of the flange plate comprises an inner shaft post and an outer shaft post.
Still further, the metal slits are provided in a radial direction.
The utility model has the advantages that:
according to the spool with the RFID tag function, based on the wheel body, the metal seam arranged at the shaft column or the flange plate is used as a slot antenna with the RFID tag to receive and transmit wireless signals, so that the RFID tag and the wheel body are integrally arranged; and can be according to the demand, based on the shape of wheel body, the position of change metal seam for RFID chip obtains the protection, in order to prevent to be damaged in the use of I-shaped wheel, prolongs its life.
The spool with the RFID tag function has the advantages of simple structure, convenience in use, certain concealment in RFID tag arrangement, strong durability, strong practicability and wide applicability.

Fig. 1 is a schematic view of a structure in which a metal seam is formed in a shaft column (fig. a is an outer side surface, and fig. b is an inner side surface).
FIG. 2 is a schematic view of a flange with metal slits (outer side of FIG. c and inner side of the shaft column of FIG. b)
Fig. 3 is a schematic structural view of a metal expansion foot.
The meaning of the symbols in the drawings is as follows: 1. the RFID device comprises a flange plate, 2, a shaft column, 3, a metal seam, 4, an RFID chip, 5, pins, 6 and a metal expansion pin.
Detailed Description
The utility model is described in detail below with reference to the drawings and the specific embodiments.
Spool with RFID tag function, RFID tag is made up of RFID chip 4 and RFID tag antenna; the RFID tag antenna is a slot antenna, namely a metal slot 3 arranged on the wheel body of the spool, as shown in fig. 3, and pins 5 of the RFID chip 4 are respectively overlapped on two sides of the metal slot 3 through metal expansion pins 6 to form the RFID tag.
The RFID chip 4 may be a silicon die or a chip subjected to plastic encapsulation.
The metal extension feet are made of metal materials, and can be metal films such as aluminum and copper, metal sheets and metal blocks. The main function of the antenna is to contact and fix the slot antenna, so that two pins 5 of the RFID chip 4 are contacted with the slot antenna.
The pins 5 and the metal extension pins of the RFID chip 4 may be glued with conductive glue, soldered or connected with metal wires.
The metal slot 3 formed on the wheel body has a certain length and width, and the size of the metal slot meets the requirement of a slot antenna. The position of the slit can be determined according to the reading direction of the RFID device and the butt joint mode.
The spool consists of a shaft column 2 and flange plates 1 arranged at two ends of the shaft column 2; according to the use requirement, the metal seam 3 can be arranged at the shaft post 2 or the flange plate 1, and specifically:
as shown in fig. 1 (a), the metal slit 3 is provided on the outer side surface of the shaft post 2 along the axial direction of the shaft post 2;
as shown in fig. 1 (b), the metal slit 3 is provided on the inner side surface of the column 2 along the axial direction of the column 2;
as shown in fig. 2 (c), the metal slit 3 is provided on the outer side surface of the flange 1 in the radial direction;
as shown in fig. 2 (d), the metal slit 3 is provided on the inner surface of the flange 1 in the radial direction and is located in the pedestal 2.
The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be appreciated by persons skilled in the art that the above embodiments are not intended to limit the utility model in any way, and that all technical solutions obtained by means of equivalent substitutions or equivalent transformations fall within the scope of the utility model.
