The present invention relates to a device for baking a fluorescent lamp coated with a fluorescent material, and more particularly, when the quartz lamp rotates to uniformly heat the quartz tube containing the fluorescent lamp, the quartz tube is moved out of position and adjacent to the quartz. The present invention relates to a fluorescent lamp baking apparatus for preventing collision with a 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 firing apparatus is performed to stabilize the heating and firing of the fluorescent material applied to the inside of the glass tube.

The fluorescent lamp baking apparatus 100, as shown in Figure 3, 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 so that the quartz block C can be transported in qualitative motion in blocks. Doing.

The quartz tube rotating unit 130 rotates the quartz tube transferred from the transfer block unit 120 by a roller (not shown) and uniformly heats the quartz tube by the heating unit 110.

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. 5, the fluorescent lamp L is inserted into the quartz tube C. The firing process is carried out in a state. Therefore, the transfer block unit 120 transfers the quartz tube C to the quartz tube rotating unit 130 in blocks, 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. 3, 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 housed in the seating groove is separated from the seating groove 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. This caused the quartz tube to be easily broken, leading to a breakdown of the fluorescent lamp located in the quartz tube. In addition, there was a problem that the entire process is delayed due to the failure of the quartz tube.

In addition, the foreign matter penetrated into the bearing O-ring caused friction between the rotating roller and the bearing, which prevented the smooth rotation of the quartz tube, which caused a limitation in the transfer of the quartz tube. Due to the problem that it is difficult to precisely transfer the quartz tube, the separation of the quartz tube occurs, which leads to breakage of the quartz tube.

The present invention has been made to solve the above problems, an object of the present invention is to rotate the quartz tube containing a fluorescent lamp to uniformly heat, the quartz tube is out of position and adjacent to the quartz tube The present invention provides a fluorescent lamp fluorescent lamp baking apparatus for preventing a collision.

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

An apparatus for baking a fluorescent lamp coated with a fluorescent material of the present invention, comprising: a transfer block having a plurality of mounting grooves formed to seat a quartz tube in which the fluorescent lamp is accommodated; A kiln for heating the quartz tube conveyed by the transfer block; And a quartz tube rotating part rotating the fluorescent lamp so that the fluorescent lamp is uniformly heated in the seating groove.

In addition, the transfer block is to load the quartz tube to the quartz tube rotating part through a trajectory movement.

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 embodiment of the present invention shown in FIG. 6 or FIG. 7 is composed of a firing furnace 210, a transfer block 220, and a quartz tube rotating part 230 as in the related art. In addition, since the firing furnace 210 is formed in the same configuration as that of the heating plates 212 and 214 located on the upper and lower sides thereof, a detailed description thereof will be omitted.

Here, the transfer block 220 is provided with a plurality of mounting grooves 222 that are open in the vertical direction. The seating groove 222 has a vertical length greater than the diameter of the quartz tube C, and the width direction thereof is equal to or larger than the diameter of the quartz tube C. When the quartz tube C transferred by the transfer block 220 is separated from the quartz tube rotating part 230 and transferred in blocks, the quartz tube C is completely inserted into the seating groove 222 and loaded, and the quartz tube rotating part ( In order to prevent the detachment of the quartz tube when the quartz tube (C) is rotated by the quartz tube rotating part 230 so that the seating groove 222 is positioned in the state wrapped around the quartz tube (C) when placed in 230 to be.

For example, the loading of the quartz tube (C) is in close contact with the bottom surface of the seating groove 222 is loaded by the trajectory movement of the transfer block, but is seated in the quartz tube rotating part 230 to seat the seating groove 222 By rotating in a state wrapped in the quartz tube, it is possible not only to prevent the respective quartz tubes from interfering with each other and to be broken, but also to prevent the quartz tube from leaving the quartz tube rotating part.

Hereinafter, the operational state of the present invention will be described with reference to FIGS. 8 to 10.

Referring to FIG. 8, the transfer block 220 is positioned below the quartz tube rotating part 230. At this time, the seating groove 222 of the transfer block 220 is the quartz block that the transfer block 220 rises in the empty state and moves upwards of the quartz tube rotating part 230 and is placed in the quartz tube rotating part 230. (C) is to be placed in the seating groove 222. At this time, the mounting groove 222 has a longer vertical length than the quartz tube (C), so that the quartz tube (C) is completely inserted into the mounting groove (222).

Next, referring to FIG. 9, the raised transfer block 220 loads the quartz tube C in a state where the quartz tube C is inserted into the seating groove 222. In this case, the quartz tube rotating part 230 is continuously rotating even if the quartz tube C rises.

Next, referring to FIG. 10, the transfer block 220 descends while the quartz tube C is inserted, and the quartz block C is placed in the quartz tube rotating part 230. The upper end of 220 is overlapped with the quartz tube rotating part 220 so as to be positioned horizontally or on the upper surface of the quartz tube rotating part 230, and the seating groove 222 is alternately disposed with the quartz tube rotating part so that the quartz tube rotating part is disposed. It encloses the quartz tube inside and enables heating. That is, the quartz tube C inserted into the transfer block 220 is continuously placed inside the seating groove 222 in the process of being heated by the kiln, and the transfer block 220 is lifted and loaded to load the quartz tube only during transfer. By doing so, the quartz tube C is prevented from being separated from the quartz tube rotating part 230 during the rotation heating by the quartz tube rotating part 230.

For example, when the transfer block 220 is moved vertically and horizontally in the upper portion of the quartz tube rotating part 230 by a trajectory movement, the transfer block 220 is transferred while the quartz tube C is inserted into the seating groove 222, and the quartz tube C is moved. During heating, the quartz tube rotating part 230 and the transfer block are positioned on the same line so that the quartz tube C is rotated and heated in the seating groove 222. When the heating is completed, the transfer block 220 is quartz. The quartz tube C placed in the quartz tube rotating part 230 is lifted and transferred to the upper side of the quartz tube rotating part 230 through a trajectory movement that moves vertically and horizontally in the downward direction of the tube rotating part 230. It is possible to prevent the quartz tube rotated and heated in a state from being separated by the rotational force of the quartz tube rotating part 230 or the quartz tubes are damaged by interfering with each other.
