The present invention relates to a fluorescent lamp manufacturing apparatus and method that can easily manufacture a fluorescent lamp, and in particular, to mass-produce a fluorescent lamp having an external electrode in a simple process.

In general, a cold cathode fluorescent lamp (CCFL) is filled with a certain amount of gas and mercury for driving the light emission of a lamp inside a glass tube coated with a fluorescent material on an inner wall thereof, and two electrodes are provided inside both ends of the tube. Formed structure.

In the light emitting action of the lamp, when a high voltage is applied to the two electrodes, electrons existing in the tube move toward the electrode (anode) and collide with each other to emit secondary electrons. The electrons collide with mercury atoms inside the tube to emit ultraviolet rays of about 253.7 nm, and the ultraviolet rays excite fluorescent materials to emit visible light.

Briefly describing the series of processes for the manufacture of the cold cathode fluorescent lamp, a process of coating the phosphor inside the glass tube (coating) and sintering the coated phosphor (baking), and exhausting and sealing the inside of the glass tube It consists of exhausts / sealings.

In the exhaust and sealing process, after evacuating the inside of the glass tube, a predetermined amount of argon gas and mercury are respectively injected, and the open end side of the glass tube is sealed as heat.

At this time, the mercury injected into the glass tube directly affects the driving and emission quality of the lamp, so that mercury liquor such as mercury capsule method, amalgam method, mercury alloy method, etc. can be improved by the high quality mercury injection quality. For example, the mercury capsule method is difficult to encapsulate liquid mercury, and the amalgam method is a melting point of solid amalgam particles such as Bi-In-Hg and Zn-Hg. Since this is relatively low, approximately 100 to 200 °, there is a problem of easily evaporating in a sealing or exhaust process.

In addition, the mercury alloy method is applicable to glass tubes having a relatively large diameter because a metal ring coated with mercury and a getter material is installed inside the glass tube, but is applied to a compact fluorescent lamp having a small diameter or a cold cathode tube for an LCD backlight. Difficult to do Problems with these mercury injection methods are mostly generated in the process for injecting mercury into the glass tube.

Therefore, a representative mercury injection method that improves the disadvantages of the above methods is the Republic of Korea Patent Publication No. 10-2004-0035060 published in April 29, 2004 patent application.

The fluorescent lamp manufacturing method using the mercury distributor is briefly described, for a fluorescent lamp containing mercury-getter material in a cup-shaped nickel or stainless container with a bottom portion of 1.0 mm to 4.0 mm in diameter and 1.0 mm to 5. mm in length. A mercury distributor is used to form a shrinkage in the exhaust pipe so that the mercury distributor does not enter the discharge tube, and after the exhaust, the mercury distributor is heated at a high frequency to inject mercury.

In particular, in the above method, the mercury distributor is installed so as not to be installed inside the glass tube, but to be hung on the contraction side formed on the section of the exhaust tube. By cutting the shrinkage portion in which the mercury distributor is located in the exhaust pipe, the mercury capsule method, the amalgam method, and the mercury alloy method may solve the problems in operation and processes.

However, the fluorescent lamp manufacturing method according to the prior art, since the mercury injecting operation is performed through the step of installing and removing the mercury distributor on the exhaust pipe side of the glass tube each time, such a process for exhausting the general fluorescent lamp manufacturing and To build a system to be linked with a series of processes such as gas injection sealing, not only is the structure complicated, but also requires excessive cost and time for manufacturing and maintenance. In particular, the mercury injection process of the above-described method is difficult to obtain a satisfactory work efficiency and productivity, etc., there is a limit to producing a large amount of lamps.

In addition, the conventional fluorescent lamp manufacturing method has a structure that is limited only to the manufacture of a cold cathode fluorescent lamp in which the electrode is formed inside the glass tube due to the mercury injection process. For example, the electrode is formed outside both ends of the glass tube and the cold cathode fluorescent lamp In addition to improving the luminous quality compared to the lamp, high-value fluorescence such as the External Electrode Fluorescent Lamp, which is known to be lighter in weight, significantly reduced in size, and excellent in lamp life, power consumption, and assembly compatibility. Since it is difficult to apply to the manufacture of lamps, it is difficult to expect satisfactory work compatibility and equipment efficiency.

In the step S1 of forming the chamber atmosphere, first, the glass tubes G are respectively inserted into and received at the holder 14 side of the cassette 4, and then the docking plate 16 fixing the holders 14. May be mounted on the chamber 2 side in the same direction as in FIG. 8.

At this time, the glass tube (G) accommodated in the holder 14 side is coated and sintered phosphor (P) inside the tube in a well-known method as shown in Figure 5, in the air approximately 1000 ?? To 1200 ?? It is heated in a range so that only one end is sealed in the same direction as shown in the drawing, the open end is protruded a predetermined portion from the docking plate 16 side, as shown in Figure 3 the heating hole of the heating plate 26 (28) The state is set inside.
