The present invention relates to a fluorescent lamp electrode coupling device. In detail, the supply / transfer of the fluorescent lamp is uniformly performed within the working period, and the fluorescent lamp electrode coupling device for improving the stability and productivity of the work by performing the operation of simultaneously bonding the electrodes on both sides of the fluorescent lamp. It is about.

It is an image display device used in notebooks, monitors, liquid crystal televisions, etc., and liquid crystal display devices such as LCDs are different from light emitting flat panel displays such as EL (Elector Luminescent) and PDP (Plasma Display Panel). Since it does not emit light by itself, it requires a separate light source.

As such a light source, the LCD is applied with a surface light source member of a BLU (Back Light Unit) or FLU (Front Light Unit). In particular, the BLU forms a surface light source at the rear of the liquid crystal panel in which the liquid crystal material is filled, so that the image formed by the liquid crystal material can be visually confirmed. Here, in order to configure the surface light source, a light guide plate which reflects light from the inside to be emitted to the liquid crystal panel side, and is used as a light source for generating light on one side of the light guide plate, CCFL (Cold Cathode Flourscent Lamp), EEFL Fluorescent lamps such as (External Electrode Flourscent Lamp) are installed.

In the fluorescent lamp applied as described above, electrodes are installed at both ends thereof, and when voltage is applied through the electrode, the fluorescent material coated inside the lamp tube is discharged to generate light.

Such a fluorescent lamp is manufactured by coating a fluorescent material inside a lamp tube made of glass material and bonding electrodes to both ends of the coated lamp tube. Particularly, in order to couple the electrodes to both sides of the lamp tube, the electrode is put on both sides of the lamp tube coated with a fluorescent material, and the lamp tube is fixed by heating and pressurizing the lamp tube at the point where the injected electrode is located, and then heating. The pressurized point is cut to complete the lamp tube.

In order to perform the above-described process of completing the lamp tube is applied to the transfer device in the working section is installed a plurality of holders that can hold the lamp tube on the outer periphery of the turntable. That is, the lamp tube fixed by the holder is conveyed in the working section by the turntable, and the fluorescent lamp electrodes are arranged by arranging respective devices for inputting electrodes, heating and pressing, cutting, and discharging the electrodes on the line of the transfer section. The coupling device is configured.

In the conventional electrode coupling device as described above, because the holder is holding the lamp tube mainly in the vertical direction, the process of joining the electrodes for the stability of the coupling operation is performed at the lower side of the device (although the operation of the upper side is possible. Instability of the device and excessive fabrication of the device by various fixtures for fixing the coupling device). Therefore, the lamp tube is to be held again to change the up and down direction by the operator after the operation of the electrode is coupled to the lower side and then the electrode coupling operation must be performed.

As a result, the electrode coupling device causes the trouble of having to re-hold the lamp tube by the operator. In addition, the electrode coupling device has a problem of significantly lowering productivity because the speed of work is greatly delayed by the reholding process.

The present invention has been invented to solve the above problems, the lamp tube is maintained in the horizontal direction when performing the operation to combine the electrode to ensure that the operation is performed in a state that is supplied / transported with a uniform supply amount to ensure the stability of the operation And, it is an object of the present invention to provide an electrode coupling device that can be performed more quickly by the process of inserting the electrodes on both sides of the lamp tube supplied / transported in the horizontal direction at the same time.
