Description

Lead wire welding apparatus using copper oxide ducted wire and lead wire produced therefrom {Lead wire fusion weld construction by using Cu2O Dumet and the Lead Wire}

The present invention relates to a welding apparatus for lead wires using Cu ₂ O Dumet wires and lead wires produced therefrom for use as lead wires for lighting lamps, incandescent lamps, fluorescent lamps, and electron tubes. Nickel wire wound by bobbin or the like is supplied from one side, copper wire is supplied from the other side, and a copper oxide oxide dumet wire whose surface is coated with a copper oxide layer from one side is supplied, so that each nickel wire and copper wire are cut to a predetermined length. The lead is finished by the pick-up loading means of the center in the state in which the copper oxide duct metal line is cut to a predetermined length, but welded by arc welding by ultra high pressure by welding means in a state of being horizontally arranged in a line. In order to obtain a wire, the bulb corresponding to the bulb or the electron tube of each lamp may be connected to the center of the lead wire. East layer dew metseon the present invention relates to lead-wire welding apparatus and a lead wire produced therefrom using the cuprous oxide layer dew metseon to completely prevent the leakage phenomenon that occurs in the handling of glass and sealed.

In general, the term "deumet wire" means to be used as a lead wire of an electric bulb or an electron tube as described above. An iron-nickel (Fe-Ni) alloy (containing about 45% nickel) ) Is made of copper wire coated on the surface with core wire.

The use of the iron-nickel alloy in this way is intended to equal the thermal expansion coefficient of the sealing glass and the coating of copper is a technique generally performed to increase the adhesion with the glass, and aids in the sealing. It is obtained by immersing in boric acid solution before use and heating it to around 100 ° C.

In addition, the Dumet wires require the general characteristics of the glass-sealing co-metal to be sealed with the glass of the electrode or the electrode tube, firstly, the thermal expansion coefficient is within the same range as the thermal expansion coefficient of the glass in a certain temperature range, and Fifth, it should not cause the change of state such as the change of thermal expansion rate in the specific temperature range. Third, the adhesion with oxide film necessary for sealing with glass should be strong. Fourth, welding, soldering, plating, and machining should be performed easily. The characteristics such as low electrical resistance and good electrical conductivity are required.

Dummet wire according to the characteristics required as described above is produced by the two kinds of wires with different properties are welded on both sides to produce a finished lead wire, it is drawn into the conduit, that is, inside the glass tube and connected to the filament to conduct electricity Nickel wire to allow light to be expressed, copper wire to be connected to the terminal supplied with power to the lower end of the glass tube, and dummet wire to be placed between the nickel wire and the copper wire to achieve excellent sealing with the glass tube. In this configuration, each of the nickel wire, the dumet wire, and the copper wire are subjected to ultra-high pressure arc welding by a separate welding device to obtain a unified lead wire.

Here, the nickel wire is iron-nickel (Fe-Ni) content is usually composed of 58% of iron (Fe) and 42% of nickel (Ni), the type of dumet wire is changed according to the copper (Cu) compounding ratio.

That is, according to the addition ratio of copper (Cu) to the above mixing ratio of iron (Fe) and nickel (Ni) can be divided into lead wires that are usually used five kinds of ductet wire, A, B, D, boron-free Dummet, nickel-plated Dummet will be described as follows. (The above name is used to classify according to the addition ratio of iron and nickel and copper in the industry.)

A Dumet wire consists of 42% of nickel (Ni) and 58% of iron (Fe), and copper (Cu) is added in an amount of 20 to 25% by weight, and the surface is obtained by boron oxidation. The coefficient of thermal expansion is similar to that of glass. Therefore, it is used for a lead wire for a light bulb, a lead wire for neon signs, a fluorescent wire lead wire, a silicon diode lead wire, and the like, which require reliability.

B Dummet wire consists of 42% of nickel (Ni) and 58% of iron (Fe), and copper (Cu) is added in an amount of 23 to 28% by weight, the surface of which is obtained by oxidizing boron. The dummet line used by the.

D Dumet's wire consists of 42% of nickel (Ni) and 58% of iron (Fe), and copper (Cu) is added in 14 to 19% by weight, and the surface is obtained by boron oxidation. Closely enhanced Dumet, suitable for thin glass applications, is mainly used for lead wires for silicon diodes and lead wires for electronic components.

The boron-free Dumet wire has 20 to 25% by weight of copper (Cu) added to the same mixing ratio of iron and nickel. Dumet Inbar, which removes the cuprous oxide film from the surface of the above A Dumet wire, has excellent weldability with other materials. It is used as an outer lead line.

Nickel-plated Dumet wire is added with 20-25% by weight of copper to the same compounding ratio of iron and nickel, and its surface is nickel-plated with a thickness of 1.5-4.0 μm. It is used as a lead wire for instrument panel light bulbs.

The present application is to provide a lead wire welding apparatus for producing and producing lead wires mainly using the A, B, D Dumet wires, such as the above.

First, in the case of the Dumet wire, the coating thickness at the time of the coating treatment has a great influence on the stability of the product and the weldability with the glass tube, and there is a problem that the defective rate is increased.

That is to say again, the nickel wire entering the glass tube and the copper wire connected to the terminal, and the dummet wire connected between the nickel wire and the copper wire, all of the inner core wire is made of nickel-iron alloy, and the copper wire is the outer surface of the core wire as described above. Copper was coated at the same mixing ratio, and the Dumet wire was obtained by coating a copper oxide layer on the outer surface of the core wire with copper.

According to the coating thickness of the copper oxide layer on the surface of the ductime wire obtained in this way, the reliability and stability of the product can be secured, and the defective rate can be reduced so that a leak phenomenon or the like does not occur when sealing the inner surface of the electrode tube.

As described above, the thickness of the cuprous oxide layer surface-treated outside the dumet line is presently 0.4 µm thick, 0.4-0.8 µm thick, 0.8-1.2 µm thick, and 1.2-1.8 µm thick. And the one having a thickness of 1.8 µm or more, and having a dumet line according to the thickness thereof, the type is classified according to the color appearing on the outer surface when sealing with glass.

Figure 6 shows a cross-sectional view of such a dumet line.

Reference numeral a denotes a core wire made of a nickel-iron alloy, reference numeral b denotes copper coated on the core wire, and reference numeral c denotes a copper oxide layer.

Hereinafter, in the present invention, a cuprous oxide layer coated with a cuprous oxide layer is collectively referred to as a dummed wire.

Therefore, in the related art, such a ducted line may be classified into various types according to the color expressed by suture with glass. Such a change may be changed depending on the thickness of the copper oxide layer coated on the outer circumferential surface of the ducted line. It is known that the use of a dumet wire in which the thickness of the copper oxide layer of the dumet wire is within a range of 1.712 to 1.881 μm is most favorable for sealing with glass tubes such as an electron tube, and a defect rate is known to decrease.

The present invention has a dumet wire in which the thickness of the cuprous oxide layer is in the range of 1.712 to 1.881 μm as described above, and the dumet wire for obtaining a unified dumet wire by ultra-high pressure arc welding treatment of copper wire and nickel wire on both sides thereof, respectively.
