The present invention relates to a torch assembly and a fluorescent lamp manufacturing apparatus using the same, which can manufacture a large amount of fluorescent lamps, and in particular, the sealing operation of the glass tube for lamp manufacturing is simple and can greatly reduce the time required.

In general, a fluorescent lamp includes a cold cathode fluorescent lamp (CCFL) in which an electrode is disposed inside a glass tube and an external electrode fluorescent lamp (EEFL) in which an electrode is disposed outside the glass tube. These fluorescent lamps are filled with a certain amount of gas and mercury for driving the light emission in a glass tube coated with a fluorescent material on the inner wall, and two electrodes are formed inside or outside the glass tube.

When the fluorescent lamps apply a high voltage to the two electrodes, electrons present in the glass tube move toward the electrode (anode) and collide with each other, thereby discharging secondary electrons, and the discharge flows through the glass tube. The electrons and mercury atoms collide with each other to emit ultraviolet rays of approximately 253.7 nm, and the ultraviolet rays excite the fluorescent material to emit visible light.

Briefly describing the series of processes for the manufacture of the fluorescent lamp, the coating of the phosphor in the glass tube for manufacturing the lamp (coating), the process of baking the coated phosphor (baking), and the exhaust of the inside of the glass tube for lamp manufacturing Sealing and sealing.

The sealing process is to inject a predetermined amount of argon gas and mercury for driving the light emission of the lamp in the state in which the inside of the glass tube is evacuated before sealing the glass tube for lamp manufacturing, and then the open end side of the glass tube is heated and sealed with a heater or the like. Let's do it.

As a method of injecting mercury into the glass tube, mercury capsule method, amalgam method, mercury alloy method, etc. are mainly used. The mercury capsule method is complicated to encapsulate liquid mercury, and the amalgam method is Bi-In. Since the melting point of the solid amalgam particles, such as -Hg, Zn-Hg, etc. is relatively low from 100 ° C to 200 ° C, there is a problem of easily evaporating in the sealing or exhaust process, the mercury alloy method is a Since separate metal rings coated with mercury and getter material can be installed, it can be applied to glass tubes with relatively large diameters, but satisfactory work compatibility can be expected for the manufacture of compact fluorescent lamps with small diameters or fluorescent lamps for backlights of LCDs. none.

As described above, a satisfactory heating efficiency is difficult to obtain in a structure in which the glass tube is sealed while indirectly heating due to the heat conduction action by the heat generation of the heater, so that excessive time is required during the sealing treatment.

Next, the fluorescent lamp manufacturing process using the fluorescent lamp manufacturing apparatus according to the present invention having the above structure will be described in detail.

Figure 9a is a preferred overall process for manufacturing a fluorescent lamp, a process (S1) for mounting a plurality of glass tubes in a sealed atmosphere corresponding to the processing space of the chamber, and through the processing space to exhaust the gas and mercury inside the glass tubes It includes the step (S2) of sealing in the injected state.

In the step (S1) of mounting the glass tube, the cassette 4, that is, the upper plate 18, is placed in the chamber as shown in FIG. 2 in the state in which a plurality of glass tubes G are stacked on the cassette 4 side, respectively. (2) is placed on the lower side and then mounted using the fixture (26).

At this time, the glass tubes (G) are coated with a phosphor therein and baked, and then heated in the air at a temperature range of about 1000 ° C. to 1200 ° C. in the air so that only one end of the glass tube G is sealed, and the opposite opening side faces upward. The cassette 4 is stacked on the side of the cassette 4 so as to be fitted.

In addition, a predetermined amount of mercury particles (A) is contained in the processing space (C) of the chamber (2) as shown in FIG. 10 on the second guide passage (H2) side of the adjusting means (6).

The exhausting step S2-1 is performed in a state where the first guide passage H1 of the adjusting means 6 is located in the processing space C as shown in FIG. 10.

That is, in the state as described above, the foreign matter or residual gas of the glass tube G is removed by the exhaust pipe L1 while being discharged through the processing space C, and the processing space ( C) Inside is a vacuum atmosphere.

In the exhaust operation as described above, the heating means 44 generates heat in a temperature range of approximately 300 ° C. to 350 ° C. in a state in which a plurality of heat generating members 46 are respectively positioned between the glass tubes G. The exhaust work inside the glass tube G is made more smooth.

Argon gas of a predetermined amount is supplied into the glass tube (G) through the gas pipe (L2) in the state positioned together. When the gas injection is completed, the gas pipe L2 is again blocked by the valve.

The mercury injection step (S2-3) is to move the adjusting means (6) in the processing space (C) so that the second guide passage (H2) to the opening side end of the glass tube (G) as shown in FIG. When the state is moved to correspond, the mercury particles (A) contained in the second guide passage (H2) side is dropped into the glass tube (G).

And, if the glass tube (G) is sealed by the above process, mercury introduced into the sealed glass tube (G) by using the heat generating members 46 of the heating means 44 installed on the fixed plate 30 side. Particles A are evaporated.

That is, while the heat generating members 46 are heated in a state located between the sealed glass tubes G, the mercury particles A introduced into the glass tubes G are inside the sealed glass tubes G. Evaporates evenly.

When the processes are completed as described above, the process space C is converted from the vacuum state to the atmospheric pressure state by operating the pressure control valve installed on the chamber 2 side, and then the cassette 4 on the chamber 2 side. You just need to separate
