DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filament fixing device for a halogen lamp used for automating the assembly of a halogen lamp.

[0002]

2. Description of the Related Art A conventional method of fixing a filament of a halogen lamp will be described below.

[0003] As shown in FIGS. 4 and 5, a filament 6 of a halogen lamp is tightly fixed by a fixing wire 7 and fixed.

A method for fixing the filament 6 with the fixing wire 7 will be described below. The coiled portion of the filament 6 is passed through the curved portion having an opening through which the filament 6 of the fixing wire 7 can be passed, and then fixed by a jig 8 or manually as shown in FIG. The filament 6 is crimped so that the filament 6 cannot pass through the opening of the wire 7, and the filament 6 is narrowed and fixed by the fixing wire 7.

[0005]

However, in the above-described conventional configuration, since the fixing wire 7 is positioned parallel to the axis of the filament 6, a part of the coil portion of the filament 6 is partially bent. In order to pass through the part, complicated movement is required, automation is difficult, and it is necessary to manually depend on it. In addition, when the fixing line 7 is swaged, the filament 6 itself is damaged by the fixing line 7. There was a problem that sometimes attached.

An object of the present invention is to solve the above-mentioned conventional problems, and to provide a filament fixing device for a halogen lamp which can automate a process of fixing a filament and does not damage a filament by swaging a fixing wire. Aim.

[0007]

In order to achieve this object, a halogen lamp filament fixing device according to the present invention is provided.
The fixing wire having a curved shape and having a caulked portion for fixing the filament through the coiled filament of the halogen lamp from the opening, the surface constituted by the caulked portion is formed by winding the coil of the coiled filament.
It includes a clamp unit to position in a state of being substantially the same angle inclination as the inclination angle of the filament wire to be formed, a configuration with a caulking fixation line crimping unit caulking portion of the fixed line from the direction perpendicular to the axis of the filament ing.

[0008]

According to this structure, the filament is supplied straight, and the fixed wire is swaged while maintaining a certain clearance between the filament and the filament.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 3, a surface provided on the fixed wire 2 and having an opening through which the filament 1 can pass and constituted by a curved caulking portion 2 a is formed by winding a coil of the filament 1. Fira
The fixed line 2 is fixed so as to be in a state of being inclined at substantially the same angle as the inclination angle of the ment wire .

In the drawing, reference numeral 3 denotes a fixed wire chuck, 4 denotes a suction chuck for the filament 1, and 5 denotes a swaging claw arranged so as to be able to swage in a direction perpendicular to the axis of the filament 1.

The operation of the filament fixing device for a halogen lamp configured as described above will be described.
First, the swaged portion 2a of the fixed wire 2 is formed by winding the coil of the filament 1 on the surface formed by the swaged portion 2a.
The filament wire is fixed by the fixed wire chuck 3 so as to be inclined at substantially the same angle as the inclination angle of the filament wire to be formed . Next, the filament 1 is supplied from above the plane of the paper in FIG. Furthermore, the caulking portion 2a of the fixed wire 2 is caulked by the caulking claw 5 in a direction perpendicular to the axis of the filament 1, so that the clearance is maintained between the filament 1 and the fixed wire 2 without rapidly squeezing the caulking portion 2a. While caulking, the filament 1 is fixed upward so as not to come off from the caulked portion 2a of the fixing wire 2.

As described above, according to this embodiment, the fixed line 2
The swaged portion 2a is formed by winding the coil of the filament 1 on the surface defined by the swaged portion 2a.
By fixing the filament 1 so as to be inclined at substantially the same angle as the inclination angle of the filament wire, the supply of the filament 1 can be simplified, and the supply of the filament 1 to the fixing wire 2 can be easily automated. Also, by caulking the fixed line 2 in a direction perpendicular to the axis of the filament 1, the filament 1 itself is not narrowed by the fixed line 2, while leaving a slight gap between the filament 1 and the fixed line 2. Can be regulated, the occurrence of scratches on the filament 1 due to caulking is eliminated, and high-quality assembling becomes possible.

[0013]

According to the present invention, the fixed wire is formed by a filament whose surface constituted by the swaged portion is formed by coil winding of the filament.
In the process of fixing the filament, the clamp unit is provided so as to be inclined at substantially the same angle as the inclination angle of the filament wire, and the fixing line caulking unit for caulking the fixing line from a direction perpendicular to the axis of the filament. An object of the present invention is to realize an excellent filament fixing device for a halogen lamp which can be automated and does not damage the filament.
