The present invention relates to a transfer quartz tube, and more particularly, to a transfer quartz tube that can be prevented from being damaged by a bump even if the interconnection is separated from the transfer position during the transfer process of the quartz tube.

LCD devices, which are being spotlighted in flat panel display devices, include non-light emitting devices that do not emit light by themselves, and thus include a backlight device that provides a separate light source.

In such a backlight device, a fluorescent lamp having a diameter of several mm is used. Cold fluorescent lamps (Cold Cathode Fluorescent Lamp) and external electrode fluorescent lamps (External Electrode Fluorescent Lamp) are used as the fluorescent lamps.

As shown in FIG. 1, the general structure of the cold cathode fluorescent lamp 10 is provided with two electrodes, a long glass tube 11 and an anode 12 and a cathode 13 attached to both ends thereof, and two electrodes. Is connected to the lead 16 is formed on both ends of the glass tube (11). In addition, a fluorescent substance 14 is coated on the inner wall of the glass tube 11, and the inner space 15 of the glass tube is filled with a mixed gas such as mercury, argon, and neon.

Meanwhile, as shown in FIG. 2, the external electrode fluorescent lamp 20 has a structure in which both ends of the glass tube 21 are sealed, and electrodes 22 and 23 are formed to surround both ends of the lamp from the outside. The electric field is discharged by forming an electric field in the glass tube 21 by (22, 23). In addition, the inner wall of the glass tube 21 is coated with a fluorescent material 24, the interior space 25 of the glass tube is filled with a mixed gas such as mercury, argon, neon.

In the case of manufacturing such a cold cathode fluorescent lamp or an external electrode fluorescent lamp, a process of applying a fluorescent material to the inside of the glass tube and firing and stabilizing it is indispensable. In this process, the fluorescent lamp baking apparatus performs a process of stabilizing heating and firing the fluorescent material applied to the inside of the glass tube.

In the fluorescent lamp baking apparatus, in order to prevent the surface of the fluorescent lamp L from being damaged and to ensure the continuity of the work, as shown in FIG. 4, the fluorescent lamp L is inserted into the quartz tube C. The firing process is carried out in a state.

The fluorescent lamp baking apparatus 100, as shown in Figure 4, the heating unit 110; Consisting of the transfer block 120, quartz tube rotating unit 130. The heating unit 110 is a component for heating the fluorescent lamp passing through the inside to a high temperature to fire the fluorescent lamp applied to the inner surface of the lamp.

The heating unit 110 includes a lower heating plate 112 disposed below and an upper heating plate 114 disposed above. In this case, the lower heating plate 112 and the upper heating plate 114 are disposed at a predetermined interval, and are fired while the fluorescent lamp is moved to a space between the lower heating plate and the upper heating plate.

In addition, the transfer block unit 120 includes a plurality of holders 122 for accommodating the quartz tube C. The transfer block unit 120 is arranged at regular intervals to transfer the quartz tube in a block unit in a trajectory motion. Doing.

The quartz tube rotating unit 130 is to rotate the quartz tube transferred from the transfer block unit 120 by a roller (not shown) to uniformly heat the quartz tube.

Therefore, the transfer block unit 120 transfers the quartz tube C to the quartz tube rotating unit 130 in block units, and the quartz tube rotating unit 130 rotates a plurality of quartz tubes C to uniformly heat the same. This is done. Then, at the position where the lamp is loaded, the lamp loading unit (not shown) inserts a new fluorescent lamp to be fired into the quartz tube C into the quartz tube, and at the position where the lamp is unloaded, the lamp unloading unit (not shown). H) discharge the fluorescent lamp inside the quartz tube and unload it to the outside.

In general, as shown in FIG. 5, the transfer block part 120 takes a trajectory that passes between the upper and lower heating plates 112 and 114 and returns to the loading position.

Then, the hot air is sprayed from one side of the quartz tube C passing through the heating unit 110 by the quartz tube rotating unit 130 to the other side to supply hot air into the quartz tube. The quartz tube (C) is moved by a predetermined pitch in accordance with a predetermined time interval and stays for a predetermined time at each position and then moves to the next position.

However, the quartz tube is very thin and relatively long, so that the quartz tube stored in the holder is separated from the holder during the transfer process, or the quartz tubes adjacent to each other in the quartz tube rotating part are separated from each other in a fixed position. As a result, the quartz tube is easily broken, leading to breakage of the fluorescent lamp located in the quartz tube. In addition, there was a problem that the overall delay due to quartz tube breakage.

The present invention has been made to solve the above problems, an object of the present invention is to provide a quartz tube for transport that can be prevented from being broken by a bump even if the interconnection is separated from the transport position during the transport process of the quartz tube In providing.

The present invention has the following configuration to achieve the above object.

A heating unit for forming a heating zone of the present invention, a transfer block unit for loading a fluorescent lamp into the heating unit while the fluorescent lamp is mounted on the quartz tube, and a quartz rotating the quartz tube loaded by the transfer block unit. A fluorescent lamp baking apparatus configured to rotate a fluorescent material on the inner wall surface of the fluorescent lamp, the tube rotating part comprising: a cap formed to surround an outer circumferential surface of the quartz tube to prevent damage due to interference between the quartz tubes; Characterized in that made.

In addition, the cap is located at both ends of the quartz tube.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

The fluorescent lamp baking apparatus 200 according to the present embodiment shown in FIG. 6 or 7 is composed of a heating unit 210, a transfer block unit 220, and a quartz tube rotating unit 230 as in the related art. In addition, since the heating unit 210 has heating plates 212 and 214 disposed on the upper and lower sides thereof, the detailed description thereof will be omitted.

Meanwhile, the quartz tube C is made of a heat-resistant material, and has a hollow tube shape, and thus the length of the transfer block part 220 and the quartz tube rotating part 230 in a state in which the lamp L is inserted therein. It is settled and conveyed along the direction. And the cap 240 is wrapped around the outer periphery of the sunset tube (C), which is the quartz tube rotating part (2) during the transfer of the quartz tube (C) by the transfer block 220 and the quartz tube rotating part 230 This is to prevent the quartz tubes from being separated from each other and collided with each other and damaged by delaying the process flow and damaging the lamp L inserted into the quartz tube C.

And it is preferable to place the cap 240 at both ends of the quartz tube (C). This is placed in the transfer block 220 and the quartz tube rotating portion 230 through the cap 240, the heating of the quartz tube (C) is hindered by the cap 240 when heated by the heating portion 210 To prevent this. In addition, the cap 240 is the same material as the quartz tube, but the heat damage is minimized when heated by the heating portion, the quartz tube (C) is shocked when the separation from the transfer block 220 and the quartz tube rotating part 230 Use absorbent materials.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

According to the transfer quartz tube of the present invention, there is an effect that can be prevented from being damaged by a collision even if the interconnection is separated from the transfer position during the transfer process of the quartz tube.
