Description

[0001] The present invention relates to a dummy glass remover,

More particularly, the present invention relates to a dummy glass removal apparatus for removing a dummy glass unnecessarily attached to a finally produced unit substrate more effectively, thereby eliminating inconvenience and troubles caused by manual operation And which can contribute to productivity improvement due to a reduction in tact time.

Recently, as the electronic display industry has rapidly developed in the semiconductor industry, a flat panel display (FPD) has begun to emerge.

A flat panel display (FPD) is thinner and lighter image display device than a cathode ray tube (CRT), which was conventionally used as a display in a TV or a computer monitor, and includes a liquid crystal display crystal display, a plasma display panel (PDP), and an organic light emitting diode (OLED).

Of such flat display devices (FPDs), OLEDs are cemented thin display devices that realize a color image by self-emission of organic materials, and have attracted attention as a promising display device of the next generation in that the structure is simple and the light efficiency is high.

OLEDs can be divided into passive PMOLEDs and active AMOLEDs depending on the driving method. In particular, AMOLED is a self-emissive display that has a faster response speed than conventional displays, has a natural color and low power consumption.

In addition, if AMOLED is applied to film rather than glass substrate, it can implement the technology of flexible display.

The manufacturing process of the OLED includes a pattern forming process, an organic thin film deposition process, a sealing process, and a bonding process in which a substrate having an organic thin film deposited thereon and a sealing process are attached to the substrate.

In the laminating process, a laminating process is performed in which a substrate having undergone a sealing process and a substrate having undergone a deposition process are adhered to each other. The substrate having undergone the sealing process becomes a lower plate and the substrate having undergone the vapor deposition process becomes a top plate.

The large-area original substrate formed in a state in which the upper plate and the lower plate are joined together is again cut into several to several tens of parts to form a unit substrate, and then an IC driver or the like is mounted on the pad portion of the unit substrate in a module process, Is released.

Accordingly, the step of manufacturing a substrate includes a cutting step for cutting (or scribing) a large-area original substrate into several to several tens unit substrates.

The cutting process for the original substrate is carried out through a separate system, usually through a cutting system, also called a scriber or scribe apparatus.

Such a cutting system generally includes a scribe unit for forming a scribe line on an original substrate and a brake unit for cutting the original substrate along a scribe line.

Through the cutting system, a scribe line is formed on the original substrate by the scribe unit, and then the original substrate is cut into a plurality of unit substrates along the scribe line through the break unit.

On the other hand, when the original substrate is cut into a plurality of unit substrates along the scribe line, it is general that unnecessary dummy glass should not be attached to the cut portions of the unit substrates.

However, there may be a dummy glass attached to the cut portion of the unit substrates for various reasons. In the past, there is no separate device for removing the dummy glass attached to the unit substrate, so that the dummy glass must be removed only by hand Which is inconvenient or troublesome, which leads to an increase in tact time and a decrease in productivity.

Hereinafter, the operation of the dummy glass removal apparatus according to the present embodiment will be described.

First, a plurality of seating stages 110, in which a cutting unit 200 sucks an original substrate, is sequentially tilted for the production of a unit substrate.

By tilting the seating stage 110, the original substrate is cut along the scribe line (see Figs. 14 and 15).

Next, the distance between the impact hands 310 is adjusted through the impact hand distance adjustment unit 320 of the impact unit 300 according to the size of the unit substrate or the dummy glass. At this time, the seating stage 110 can be moved so that the dummy glass is positioned right under the impact hand 310 through the seating stage moving unit 400 of the stage unit 100.

Next, the striking hand 310 is lowered and strikes the dummy glass, so that the dummy glass is removed from the unit substrate.

As described above, the dummy glass removing apparatus according to the present embodiment includes the striking hand interval adjusting unit 320 that adjusts the distance between the striking hands 310 in the striking unit 300, It is possible to easily adjust the separation distance between the impact hands 310 according to the size, thereby contributing to an improvement in productivity due to a reduction in tact time.

Although the present invention has been described in detail with reference to the above drawings, the scope of the scope of the present invention is not limited to the above-described drawings and description.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
