Description

Heater block mounting apparatus

The present invention relates to a heater block fixing device, and more particularly to a heater block fixing device that can facilitate the height adjustment and parallelism of the heater block.

Among the flat panel display devices, since the liquid crystal display device is a non-light emitting device that does not emit light by itself, a backlight device for providing a separate light source is required.

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

Referring to the general structure of the cold cathode fluorescent lamp 10, as shown in Figure 1, the bulb 11, which is a long glass tube, and the anode 12 and the cathode 13 are attached to both ends thereof, the two electrodes are the bulb It is comprised by the lead 16 formed in the both ends of (11). In addition, the inner wall of the bulb 11 is coated with a fluorescent material 14, and the inner space 15 of the bulb 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 bulb 21 are sealed, and electrodes 22 and 23 are formed to surround both ends of the lamp 20 from the outside. The external electrodes 22 and 23 form an electric field in the bulb 21 to discharge gas. In addition, a fluorescent material 24 is coated on the inner wall of the bulb 21, and the inner space 25 of the bulb is filled with a mixed gas such as mercury, argon, and neon.

In order to manufacture such a cold cathode fluorescent lamp or an external electrode fluorescent lamp, a fluorescent material is applied to the inside of the bulb by a fluorescent material coating device, and a process of firing and stabilizing it by a sintering device is inevitably performed.

The firing apparatus is completed by loading a bulb coated with a fluorescent material between the upper heater and the lower heater, heating and firing by the heaters, and then unloading the fired bulb.

However, since the bulb is a glass tube with a very thin thickness, the bulb may be damaged by hitting each other during loading and unloading. In particular, when the bulb is fired by the upper and lower heaters, the bulb is rotated in order to transmit heat evenly, and breakage of the bulb frequently occurs during such rotational movement.

Therefore, in order to solve this problem, as shown in Figure 3, the bulb (L) is inserted into the quartz tube (C) to be loaded, rotated, unloaded and fired. In this way, when the quartz tube C is used, not only the breakage of the bulb L can be prevented, but also a side effect of ensuring the continuity of the work. In FIG. 3, one bulb L is inserted into the quartz tube C, but it is generally advantageous to insert the three bulbs into the quartz tube to perform the process.

Looking at the configuration of the conventional fluorescent lamp firing apparatus with reference to Figure 4 in more detail. Conventional firing apparatus 100 is a quartz tube loading elevator 110, a loading unit (not shown) for loading the bulb (L) in the quartz tube (C), and the quartz tube (C) the upper heater ( A plurality of transfer blocks 130 to be transferred between the 121 and the lower heater 122, a rotary roller 141 for rotating the quartz tube (C) carried by the transfer block 130, and a quartz tube (C) ) And an unloading part (not shown) for unloading the bulb L fired from), and an elevator 150 for unloading the quartz tube bulb. The quartz tube descending on the unloading elevator 150 is transferred to the loading elevator 110 through the collecting conveyor 152 again. The upper heater 121 and the lower heater 122 is fixedly installed inside the heater block 120.

Here, the upper heater 121 and the lower heater 122 should be disposed close to the quartz tube (C) at an appropriate distance, in particular should be installed in parallel.

5 is an apparatus 200 for adjusting height and parallelism of the heater block 120. Referring to FIG. 2, the heater block 120 is supported by support members 220 fixed to inner walls of both sides of the frame 210. In addition, the heater block 120 supported by the support member 220 is adjusted in height and parallelism by the height adjustment bolt 230.

However, the work for adjusting the height and parallelism of the heater block 120 by the height adjustment bolt 230 is very difficult and time-consuming problem.

The present invention has been made to solve the above problems, the object of the present invention to provide a heater block fixing device that can facilitate the height adjustment and parallelism of the heater block.

In order to solve the above technical problem, a heater block fixing device according to the present invention includes a frame; A support member movably installed on both inner walls of the frame to support the heater block; And a driving source for elevating and driving the support member.

In addition, guide rails are formed on both inner walls of the frame, and the support member is preferably moved vertically along the guide rail.

In addition, it is preferable that a fixing means such as a fixing pin or fixing bolt for fixing the support member to the frame is further provided.

In addition, the drive source is preferably an air cylinder.

According to the present invention, there is an effect that can facilitate the height adjustment and parallelism of the heater block.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the heater block fixing apparatus according to the present invention.

Referring to FIG. 6, the heater block fixing device 300 according to the present invention includes a frame 310, a support member 330, and a driving source 320.

The frame 310 is provided with guide rails (not shown) in the vertical direction on both inner walls.

The support member 330 is a component for supporting the heater block 120 and is installed to be movable along guide rails formed on inner walls of both sides of the frame 310.

In addition, a driving source 320 for elevating the support member 330 is provided below the support member 330. In this embodiment, the driving source 320 is an air cylinder, and thus the support member 330 is lifted by the cylinder rod 321. However, alternatively, it can also be comprised by a motor etc. as a drive source.

In addition, fixing means (not shown) for fixing the support member 330 at a position set by the driving source 320 is provided. Although not shown, the fixing means may be fixing pins or fixing bolts penetrating both side walls of the frame 310.

Hereinafter, an operating state of the heater block fixing device 300 according to the present invention will be described with reference to FIG. 6.

First, the heater block 120 is placed on the support members 330 formed on both inner walls of the frame 310. In this state, one or both of the driving sources 320 are operated to raise or lower the supporting member 330 to adjust the height of the heater block 120 and the parallelism with the quartz tube.
