1 and 2, the intelligent wire 100 includes a core wire 110, an insulating layer 120, a radio recognition tag 130, and an outer coating layer 140.

The core wire 110 is a conductor located at the center of the wire, and serves as a passage through which current flows, and an allowable current of the wire is determined according to its surface area. The core wire 110 may include one copper wire, a copper clad aluminum wire, or a stranded wire made by twisting a plurality of wires at a constant pitch.

The insulating layer 120 is installed to surround the core wire 110 and prevents leakage of current. As the material of the insulating layer 120, polyvinyl chloride (PVC), polyethylene (PE), crosslinked polyethylene (XLPE), nylon, rubber, or the like may be used. The insulating layer 120 may be formed in a manner that the insulating layer 120 is applied on the core wire 110 in a temperature atmosphere of about 170 ° C. to about 250 ° C. and then cured according to the insulating material.

The outer coating layer 140 is installed to simplify the wire laying operation while protecting the insulating layer 120 and the radio recognition tag 130. The outer coating layer 140 may be formed of a material similar to the insulating layer 120. For example, polyethylene, polyvinyl chloride, natural rubber, butyl rubber, ethylene propylene rubber, chloroprene rubber, or the like may be used as the material of the outer coating layer 140.

A radio recognition tag 130 is disposed between the insulating layer 120 and the outer coating layer 140.

The structure, arrangement, and form of the RFID tag 130 is for convenience of description and is not intended to limit the present invention to such structure, arrangement, or form.

An intelligent wire having a wireless identification tag will be described in more detail below.

4 is a flowchart illustrating a method of manufacturing an intelligent wire according to an embodiment of the present invention.

Referring to FIG. 4, in order to manufacture an intelligent wire, an insulating layer is first formed on a core wire (S410). For example, the insulating layer may be formed by applying and curing the liquid insulating material 740 through the nozzle 730 on the core wire 710 flowing into the inlet hole 720 in the insulating layer forming portion (FIG. 7).

Next, a wireless recognition tag is installed on the insulating layer (S420). The radio recognition tag may be installed directly on the insulating layer or mounted on a functional layer such as a tape.

Next, an outer coating layer is formed on the insulating layer provided with the radio recognition tag (S430).

In step S430 of forming the outer cladding layer, the temperature of the outer cladding material may adversely affect the RFID tag. More specifically, the outer coating layer material is melted at about 170 ° C. to about 250 ° C., although it depends on the type of material.

That is, the outer coating layer forming step, such as insulation process, bedding process, sheath process, etc., has a working temperature of up to about 170 ° C. or up to about 250 ° C., depending on the coating material, and the tubing process has a working temperature of up to about 150 ° C. Has As a result, the wire manufacturing process involves a situation in which the outer surface of the wire can be heated to a temperature range of about 170 ° C to about 250 ° C in each step.

On the other hand, most RFID tags typically operate at temperatures up to about 80 ° C. to less than about 150 ° C., and are easily damaged when exposed to temperatures above about 150 ° C.

Accordingly, the step 430 of forming the outer coating layer of the present embodiment and other heating accompanying the wire fabrication process is performed within a period of time, for example, within about 1 second, without substantial damage to the RFID tag attached or inserted into the wire. It is required to reduce the temperature of the wire material in contact with the tag to about 150 ° C. or less, preferably to reduce it to about 80 ° C. or less.

In other words, the step of forming the outer coating layer of the manufacturing method according to the present embodiment (S430) after applying the outer coating layer material on the insulating layer and the radio recognition tag and rapidly cooling the outer coating layer material to form the outer coating layer Include.

On the other hand, the above-mentioned rapid cooling temperature is described in consideration of the operating range of the current RFID tag, and if the heat resistance of the RFID tag is improved in the future, the process may be performed at a temperature higher than the aforementioned temperature.

5 and 6 will be described in detail with respect to the process of rapid cooling the outer coating layer formed.

5 is a view for explaining a process that can be employed in the manufacturing method of the intelligent wire according to an embodiment of the present invention. 6 is a view for explaining the main process that can be employed in the method of manufacturing an intelligent wire according to an embodiment of the present invention.

The RFID tag according to the present embodiment may be disposed on the insulator or the union through an association process or a shielding process in a state of being pre-mounted on a functional tape forming a functional layer in an electric wire. For example, as illustrated in FIG. 5, an intelligent wire 520 of an intermediate product may be manufactured using a functional tape 510 mounted with a radio recognition tag (not shown) in an association process or the like. The association process refers to a process of twisting a plurality of insulators having a core wire and an insulating layer according to a predetermined arrangement rule, and the shielding process refers to a process of winding copper wire braid, copper tape tape, and aluminum tape on the insulator or the union.

The intelligent wire 520 of the intermediate product described above refers to a wire on which a protective layer, such as an insulating layer or an outer covering layer, must be additionally formed. That is, the intelligent wire 520 of the intermediate product described above refers to the product of the intermediate process for manufacturing the intelligent wire of the finished product. In particular, the intelligent wire 520 of the intermediate product according to the present embodiment is manufactured while preventing the RFID tag from being damaged by the high temperature insulating material in the subsequent formation of the insulating coating layer. An example of a process for preventing damage to the RFID tag will be described in more detail below.

Referring to FIG. 6, the manufacturing apparatus according to the present exemplary embodiment is installed to rapidly cool the electric wire 120a coming from the discharge part 570 of the discharge head 560 of the insulating layer forming part 500. Here, the wire 120a may be regarded as having a insulating layer which is not yet completely cured after being applied on the core wire.

For the rapid cooling described above, the manufacturing apparatus of the present embodiment may include a refrigerant shower unit and / or a cooling bath 650.

The refrigerant shower unit includes a refrigerant storage unit 610, at least one refrigerant transfer pipe 620, and at least one refrigerant injection hole 630. The cooling tank 650 includes a tank 660 in which the refrigerant 670 is filled to a predetermined height, and pipes 680 and 690 for circulation of the refrigerant 670 between the tank 660 and the heat exchanger (not shown). do.

Although the cooling tank 650 of this embodiment is shown as being installed at the rear end of the refrigerant shower unit, it is merely for convenience of illustration, and the configuration of the present invention is not limited thereto.

For example, the cooling tank 650 may be installed as close to the insulating layer forming part 500 as possible to cool the wire 120a substantially simultaneously with the refrigerant shower part. As another example, a rapid cooling process of the wire 120a may be performed by arranging only the cooling tank 650 close to the rear end of the insulating layer forming unit 500.

In addition, without damaging the RFID tag mounted on an intelligent wire, it is necessary to rapidly cool the insulating material on the RFID tag and to form an insulating layer on the RFID tag. In the example, the type or temperature of the refrigerant may be set differently according to the insulating material of the insulating layer.

For example, water, air, helium, nitrogen, or a combination thereof may be used as the refrigerant. In the case of the water or air refrigerant, the temperature may be controlled at 0 ° C. or more and room temperature or less, but the refrigerant is used for rapid cooling. You can adjust the amount or feed rate.

In addition, in the manufacturing apparatus according to the present embodiment, it may be considered that the device for rapid cooling or a component including the same does not contact the refrigerant directly to the wire 120a, but such a configuration has a cooling effect as compared to the direct cooling method. Since it is separated, it may be employed as an auxiliary cooling means separately from the above-described refrigerant shower or cooling tank 650.

The RFID tag mounted on the intelligent wire according to an embodiment of the present invention may be directly mounted on the insulating layer, which will be described in detail below.

FIG. 8 is a view for explaining a discharge hole that may be employed in the method for manufacturing the intelligent wire of FIG. 7. FIG. 9 is a partial perspective view illustrating a wire structure of an intermediate product manufactured by the discharge hole of FIG. 8.

Referring to FIG. 7, a process of forming an inner insulation layer or an outer insulation layer (or an outer covering layer) of an intelligent wire may apply a liquid insulation material 740 on the core wire 710 through the nozzle 730 and insulate the insulation material 740. ) May be performed by extruding the coated core wire 710 into the discharge hole. Here, the discharge hole may correspond to the discharge hole formed in the discharge part 570 of the discharge head 560 of the insulating layer forming part 500 of FIG. 6.

The discharge head 860 has a screw fastening hole 862 for coupling with the body of the insulating layer forming part, and a discharge part 870 disposed at the center of the discharge head 860 so that a discharge hole 890 having a predetermined length is formed. It is provided.

A wireless recognition tag 930 may be disposed in the groove 922 of the insulating layer 920 formed by the above-described configuration, as shown in FIG. 9. The radio recognition tag 930 may correspond to the radio recognition tag 130 of FIG. 3.

In the insulating layer 920 surrounding the core wire 910, the width W of the groove 922 may be considerably smaller than the diameter of the insulating layer 920. For example, the width W of the groove 922 may be set in the range of about 1 mm to about 10 mm depending on the diameter of the insulating layer 920.

On the other hand, although not clearly shown in Figure 9, the cross section of the insulating layer 920 may be formed to have a substantially circular cross section while having a groove.

In this embodiment, after the radio recognition tag 930 is installed in the groove 922 of the insulation layer 920, another insulation layer or an outer coating layer covering the insulation layer 920 and the radio recognition tag 930 is formed. In this case, the rapid cooling process described above with reference to FIG. 6 may be introduced substantially the same in order to prevent the RFID tag 930 from being damaged by the high temperature insulating material in the subsequent process.

Next, a separate outer coating layer covering the RFID tag is partially formed (S1030). According to this step (S1030), the band or band-shaped outer coating layer is formed only for the radio recognition tag, thereby simplifying the process.

In particular, when damage to the RFID tag is expected when the outer coating layer is formed, the rapid cooling process may be performed after forming the strip or band-shaped outer coating layer similarly to the rapid cooling process described above with reference to FIG. 6. . Of course, the rapid cooling process may be omitted depending on the material of the strip or band-shaped outer coating layer.
