Description

Ionizer device {A IONIZER SYSTEM}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ionizer device, and more particularly, to an ionizer device that can easily change the direction of static electricity by simply adjusting a tip portion during electrostatic static electricity using the ionizer.

In general, a liquid crystal display device displays an image by injecting a liquid crystal between two substrates, and adjusting an amount of light transmission by adjusting an intensity of an electric field applied to the liquid crystal.

Such liquid crystal displays commonly generate static electricity in almost all processes through deposition, etching, and liquid crystal cell processes on a transparent glass substrate. It acts as a factor to reduce product defects and yields such as device breakdown and dielectric breakdown caused by (Electro StacticDamage).

Since these ESD phenomena are also numerous, it is difficult to quantify or classify them correctly.However, efforts to prevent and disperse static electricity by using a protection circuit or insertion of a diode or a shorting bar are continued. have.

If the static electricity is not removed, the yield of the product is greatly reduced. In particular, the quantity and sub inspection of the panel must be carefully prepared for the static electricity.

That is, when the panel is lit and visually inspected in the state where liquid crystal injection is completed, the inspector inspects the panels one by one to determine whether the panel is positive or negative. If the static electricity is locally charged on the surface of the panel, the liquid crystal may be turned on. When the charged part looks like a defect.

In other words, since the static electricity automatically disappears over time, the liquid crystal panel is actually a good product. However, since the stain is generated by the static electricity, it can be mistaken as if it is a bad product. It is.

In view of this, when the amount or negative judgment of the liquid crystal panel is performed, the inspector may judge that the stain is caused by a simple static electricity, even though the stain is caused by other defects in the spot where the stain is generated, not by a simple static electricity stain. This may result in judging the liquid crystal panel which is actually defective as good.

As a result, failure to deal fully with static electricity can have a major impact on product yield, and various approaches are being sought to remove static electricity.

1 is a diagram illustrating a liquid crystal display device having a shorting bar according to the related art. As shown in the drawing, the liquid crystal display device in which the shorting bar is formed adopts a structure in which a common short line 1 is provided outside the TFT array.

That is, the end of each data bus line 3 is shorted by the common short line 1, and each gate bus line 5 is also configured such that the end thereof is shorted by the common short line 1. do.

The common short line 1 may be electrically connected to each other to prevent a short between bus lines due to static electricity. At this time, after the manufacturing process of the liquid crystal display device is completed, the common short line 1 is removed by cutting the substrate 10 along the cutting line 7.

On the other hand, unlike the antistatic structure of the liquid crystal display device, the static electricity flowing into the antistatic object may be eliminated by direct charging of ions generated in the ionizer.

There are various types of ionizers called ionizers, depending on the application range. Among them, an AC-driven ionizer mainly used in liquid crystal displays will be described as an example.

2 is a view schematically showing the structure of a conventional ionizer device. As shown therein, the ionizer device discharges the high voltage transmitted from the main body portion 21 and the high voltage transferred from the main body portion 21 to generate a positive and negative ions. A plurality of tips 22 formed thereon; A tip connection unit (24) for fixing the tip (22) to the body portion (21); The tip 22 has a cylindrical shape to be inserted, and is configured to include a tip holder 23 for blowing gas (+) ions and (-) ions supplied from the tip 22.

In addition, the tip connection unit 24 and the tip holder 23 are coupled, and the tip holder 23 is formed with an air supply hole so that nitrogen gas or air can be supplied from the outside.

A high voltage generator (not shown) is provided inside the main body 21 so that when a high voltage is delivered to the tip, when electricity is discharged from air, positive and negative ions are periodically generated.

(+) Ions and (-) ions generated in the tip 22 approaches the static electricity elimination object 25 along the airflow to neutralize the static electricity.

In more detail, the antistatic material 25 is a process of scribing and breaking a cell to form a glass substrate in units of static electricity in the process of forming various patterns with a glass substrate of a liquid crystal display device. A lot of static electricity flows in.

Therefore, after forming various patterns on the glass substrate, the glass substrate is placed under the ionizer to remove static electricity generated in various manufacturing processes or after completing the scribe and break processes, on a cell-by-cell basis. The separated liquid crystal panel is positioned under the ionizer to remove static electricity introduced into the panel.

FIG. 3 is a view illustrating a blow direction of ions in an enlarged structure of portion A of FIG. 2. As shown therein, in the ionizer having the structure as described above, the tip holder 23 is formed in a structure fixed to the tip connecting unit 24 and cannot be easily changed in direction, from the tip 22. The generated positive and negative temperatures always flow in the same direction.

Therefore, in order to change the blow direction of the (+) ion and the (-) ion on the antistatic object 25, a problem arises in that the direction of the ions coming out of the ionizer is changed by moving the entire ionizer device.

SUMMARY OF THE INVENTION An object of the present invention is to provide an ionizer device that can easily change the direction of static electricity by simply adjusting a tip portion during electrostatic static electricity using the ionizer.
