Abstract
The present invention relates to a fluorescent lamp bulb aligning device, the fluorescent lamp bulb aligning device according to the present invention, the device for aligning the bulb before supplying the sealed bulb to the exhaust, comprising: a loading conveyor for transporting the sealed bulb; Alignment means for aligning the bulb transferred through the loading conveyor in a direction perpendicular to a traveling direction of the loading conveyor; And an unloading conveyor for supplying the aligned bulbs to the exhaust machine.
According to the present invention, when sealing the other end of the bulb, the bulb is moved in the direction perpendicular to the moving direction of the bulb so as to be located on the same line without being reversed by a separate reversal robot, thereby preventing bulb damage due to volume reduction of the equipment and impact. It can be effective.

The present invention relates to a fluorescent lamp bulb aligning device, and more particularly, in the sealing of the other end of the bulb by transferring the bulb in the direction perpendicular to the moving direction of the bulb so that the bulb is located on the same line without inverting by a separate inverting robot. The present invention relates to a bulb alignment device of a fluorescent lamp that can prevent bulb damage due to volume reduction and impact.
In general, liquid crystal display (LCD) devices that are spotlighted in flat panel display devices include a backlight device that provides a separate light source because they are non-light emitting devices that do not emit light by themselves.
The general requirements of such a backlight are high brightness, high efficiency, uniformity of brightness, long life, thinness, low weight, and low cost. In the case of notebook PCs, high efficiency long life lamps are required to reduce power consumption, and backlights for monitors and TVs require high brightness.
As the backlight device, 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.
As shown in FIG. 1, the general structure of the cold cathode
Meanwhile, as illustrated in FIG. 2, the external electrode
In the case of manufacturing such a cold cathode fluorescent lamp or an external electrode fluorescent lamp, a similar process is performed, but a minute part undergoes a different process. In each manufacturing process, the sealing process of vacuuming the inside of the fluorescent lamp and filling gas therein, and the sealing process of removing unnecessary parts while maintaining the sealing state in the completed fluorescent lamp, which are necessary in the manufacturing process, Since the fluorescent lamps are different for each manufacturing method, they will be described briefly here.
The cold-cathode fluorescent lamp and the external electrode fluorescent lamp are divided into two parts, and the external electrode fluorescent lamp is divided into the case of using beads and the case of not using them.
First, in the case of a cold cathode fluorescent lamp, a bead process is performed to form the
Thereafter, after completing another process such as filling the gas into the
On the other hand, the external electrode fluorescent lamp undergoes a different process from the cold cathode fluorescent lamp because the electrode is formed on the outer surface of the glass tube. First, let's look at the case of not using beads. If no beads are used, no bead process is necessary.
Therefore, as shown in Fig. 4a, the sealing process proceeds from the beginning. In this sealing process, first, one end portion of the
Next, in the thread cutting process, as shown in FIG. 4B, the cutting portion of the
On the other hand, when the external electrode fluorescent lamp is manufactured using the beads, a bead process is required. However, unlike the cold-cathode fluorescent lamp, in this case, since the beads do not act as electrodes, they simply serve to help seal the sealing process of the glass tube. Accordingly, as shown in FIG. 5A, the external electrode fluorescent lamp is manufactured in the shape of the
Next, in the sealing process, as shown in FIG. 5B, the

However, when the bulb B is inverted by rotating in the vertical direction, the volume of the equipment increases, and when the bulb B is inverted, the bulb B is separated from the
The present invention has been made to solve the above-mentioned problems, the object of the present invention is to transfer the cylinder in the direction perpendicular to the direction of movement so as to be located on the same line without inverting the bulb when sealing the other end of the bulb by the volume reduction and impact of the equipment The present invention provides a bulb alignment device for a fluorescent lamp that can prevent bulb damage.
In order to achieve the above object, the present invention provides an apparatus for aligning the bulb before supplying the sealed bulb to the exhaust, comprising: a loading conveyor for transporting the sealed bulb; Alignment means for aligning the bulb transferred through the loading conveyor in a direction perpendicular to a traveling direction of the loading conveyor; And an unloading conveyor for supplying the aligned bulbs to the exhauster. When sealing the other end of the bulb with one end sealed as in the prior art, the bulb which has one end sealed without rotating the bulb is reversed. By pushing the bulb horizontally in the direction perpendicular to the movement direction of the bulb toward the stopper provided in the exhauster direction, each bulb is positioned on the same line, thereby reducing the equipment cost due to the volume reduction of the equipment and preventing damage to the bulb. desirable.
