Generally, cutting into a unit glass panel is performed by forming a scribe line on the surface of the glass panel with a cutter having a hardness higher than that of glass, and propagating a crack along the scribe line .

As an example of a scribing assembly for performing the scribing process, there is a belt conveyor type scribing assembly (hereinafter referred to as "the prior art"). Referring to FIGS. 1 to 3, It is as follows.

As shown, the prior art scribing assembly comprises a transport unit 10 and a scribing unit 20.

The conveying unit 10 uses a roller conveyor or the like as a part to which a glass panel (mother board 1) is loaded and aligned in advance and conveyed to a subsequent scribing area.

The scribing unit 20 includes a scribing head support 22 for guiding the movement of the scribing head 21, a conveyance belt 23 for conveying the glass panel 1, And a glass chuck unit 24 for holding the panel 1 at a rear end in the conveying direction.

As shown in Fig. 2, the glass chuck unit 24 is an essential component for preventing the shake of the glass panel 1 during conveyance and for forming an accurate scribing line.

The scribing head 21 is connected to the upper substrate (any one of the color filter substrate and the thin film transistor array substrate) and the lower substrate (the other of the color filter substrate and the thin film transistor array substrate) One head) and the lower head are installed together so as to scribe each of them.

The conveyance belt 23 and the glass chuck unit 24 move the glass panel 1 in the conveying direction (Y-axis direction) in the state where the scribing head support table 22 is stopped, The scribing line is formed on the upper and lower sides of the glass panel 1 and then the scribing line is formed along the longitudinal direction of the scribing head support 22 in a state where the conveying belt 23 is stopped, The scribing head is moved to form a scribing line in a direction (X axis) orthogonal to the transport direction.

Then, the glass panel 1 on which the scribing process has been completed is conveyed to a subsequent braking zone and is braked by the braking unit 50 shown in the figure.

However, even if the glass panel 1 is gripped by the glass chuck unit 24, the glass panel 1 is uniformly supported over the entire area due to the characteristics of the conveyor belt 23, Therefore, there is a disadvantage that the uniform load is not applied to the surface of the glass panel when the scribing is performed, thereby deteriorating the quality.

3, when the projections 23a sandwiching the grooves of the drive roller 27 are formed on the inner surface of the conveyance belt 23, the projections 23 23a rise up from the groove and cause the glass panel 1 to swing up and down, which adversely affects the scribing quality.

The scribing head 200 may be a scribing module that includes not only a scribing head but also a cutter and a lifting and transporting mechanism. In addition, an upper head and a lower head are provided on the upper and lower portions of the glass panel so that the upper substrate and the lower substrate of the lapped glass panel can be simultaneously scribed.

The scribing head support 300 guides the movement of the glass panel 100 in the horizontal direction Y. The scribing head support 300 may include a linear motion guide (not shown) and a linear motor.

The glass chuck unit 400 serves as a component for gripping the rear end of the glass panel 100 with reference to the transport direction, while preventing the glass panel 100 from shaking to the left and right.

4 and 5, the glass chuck unit 400 includes a glass chuck unit main body 410 arranged in the horizontal direction at the upper portion of the glass panel, and a glass chuck unit main body 410 installed at the glass chuck unit main body 410 A plurality of glass chucks 420 for gripping the rear end of the glass panel 100 with respect to the transport direction and a glass chuck unit moving unit 430 for moving the glass chuck unit body 410 in the transport direction of the glass panel .

The glass chuck unit main body 410 is connected to the glass chuck unit moving part 430 by being extended in the horizontal direction (X axis) as a part where the plurality of glass chucks 420 are detachably coupled. A plurality of glass chucks 420 coupled to the glass chuck unit main body 410 and the glass chuck unit main body 410 can move along the transport direction (Y axis) by the operation of the glass chuck unit moving part 430 .

The glass chucks 420 are coupled to the glass chuck unit body 410 such that the glass chucks 420 are spaced apart from one another along the horizontal direction.

A plurality of air injection holes 500 are formed at the bottoms of the first transfer part F1 and the second transfer part F2. In order to float the glass panel 100 without bending, it is preferable that the air injection holes 500 are uniformly formed on the bottom surface of the imaginary plane to which the glass panel 100 is transferred.

The portion R where the air injection hole 500 is formed in the first transfer portion F1 or the second transfer portion F2 may be uniformly distributed over the entire area of the glass panel 100 to be transferred, And may be arranged in a plurality of rows with a predetermined interval C therebetween.

Particularly, the lengthwise direction of the gap C is made to coincide with the conveying direction of the glass chuck 420, and the portion of the glass panel 100 which is covered by the glass chuck 420, It is desirable to eliminate the portion that makes the force non-uniform.

A nozzle (not shown) for spraying high-pressure air, a hose or cable connected to the nozzle, and an air tank may be disposed below the air injection hole 500.

A conveying roller or a guide belt 600 is installed on both sides of the first conveying unit F1 and the second conveying unit F2.

It is preferable that the conveying roller or the guide belt 600 guides both sides of the glass panel 100 to be conveyed for scribing or completed and scribed to maintain a predetermined alignment state.

That is, according to the embodiment of the present invention, when the actual glass panel 100 is scribed while the glass chuck 420 grasps, the conveying roller or the guide belt 600 contacts the glass panel 100 When the glass panel 100 is brought in or scribed for scribing and is conveyed, the conveyance roller or the guide belt 600 is rotated while both sides of the glass panel 100 are rotated So that the alignment state can be maintained satisfactorily.

For this purpose, it is preferable that a displacement driving device 800 is installed on the conveying roller or the guide belt 600 so that the conveying roller or the guide belt 600 can be displaced by a predetermined amount in the transverse direction. In this case, the displacement driving device 800 may be constituted by a pneumatic or hydraulic cylinder or a gear device.

On the other hand, a glass panel transfer part 700 is disposed in a previous stage of the first transfer part F1 in which the air injection hole is formed. The transport unit 700 may include a timing belt, a general roller type conveyor, or a belt type conveyor. The timing belt has no slip and a relatively accurate rotation ratio can be obtained, so that the speed can be accurately matched with the conveyance roller or the guide belt 600, which will be described later.

Hereinafter, the operation of the scribing assembly according to the present invention will be described.

First, the glass panel 100 is precisely conveyed from the conveying unit 700 having the timing belt.

When the glass panel 100 to be transferred enters the region R where the air injection hole 500 formed in the first transfer part F1 is formed, air is blown onto the lower surface of the glass panel 100, The conveying rollers or the guide belts rotating on both sides of the rear glass panel are brought into contact with each other and the precise conveyance is performed until the rear end of the glass panel in the conveying direction reaches the position of the glass chuck 420.

In this case, the linear velocity of the timing belt needs to be kept equal to the linear velocity of the conveyance roller or the guide belt.

Next, the glass chuck 420 descends to grip the rear end of the glass panel 100 with reference to the transport direction. Since a plurality of glass chucks 420 are provided on the glass chuck unit main body 410 along the lateral direction orthogonal to the conveyance direction, the gripping force acting on the glass panel 100 can be dispersed, and in particular, The gripping force can be maintained evenly.

Next, the glass chuck unit 400 scribes the transport direction (Y axis) by the scribing head 200 while transferring the glass panel without restricting both sides of the glass panel 100 .

When the glass panel 100 is scribed along the conveying direction, the glass chuck unit 400 grasps the glass panel 100, so that the conveying roller or the guide belt 600 supports the side surface of the glass panel no need. When the side surface of the glass panel 100 is supported, it may act as a frictional resistance, so that accurate scribing may not be performed.

In order to separate the conveying roller or the guide belt 600 from both sides of the glass panel 100, a displacement driving device 800 such as a pneumatic cylinder or a hydraulic cylinder may be used.

Subsequently, the scribing head 200 moves in the lateral direction along the scribing head support 300 while performing the stepwise displacement of the glass panel 100 along the conveying direction (Y axis) to perform scribing.

Finally, on both sides of the scraped glass panel 100, the rotating conveying roller or the guide belt 600 is brought into contact again and conveyed to a breaking zone where the breaking process is performed. It is necessary to keep the linear velocity of the conveying roller or the guide belt 600 equal to the linear velocity of the breaking zone belt.

Although the preferred embodiments of the present invention have been described in detail, it should be understood that the technical scope of the present invention is not limited to the above-described embodiments, and various modifications and variations may be made within the scope of the following claims.
