Description
The present invention relates to a cutting device used for manufacturing a flat panel display panel, and more particularly, to a transfer unit for a cutting device for cutting a mother substrate for a flat panel display panel, a cutting device having the same and a cutting method using the same.
In general, a plurality of flat panel display panels for displaying an image such as a liquid crystal display panel are manufactured at a time by using a large panel, that is, a mother substrate. In detail, the flat panel display panel includes an upper substrate and a lower substrate facing each other. The upper substrate and the lower substrate are formed through different mother substrates. That is, each of the upper substrate mother substrate and the lower substrate mother substrate is divided into a plurality of unit regions. In each unit region of the upper substrate mother substrate, an upper cell formed of thin layers for forming the upper substrate is formed. In each unit region of the lower substrate mother substrate, a lower cell formed of thin layers for forming the lower substrate is formed.
The upper substrate mother substrate and the lower substrate mother substrate, each of which the thin film layers are formed, are coupled to face each other, and the unit regions of the upper substrate mother substrate and the unit regions of the lower substrate mother substrate coincide with each other. The lower cell and the upper cell facing each other constitute one unit cell, and one unit cell constitutes one flat panel display panel. Two mother substrates coupled to each other are cut for each unit cell, thereby manufacturing a plurality of flat panel display panels.
As described above, in order to manufacture a plurality of flat panel display panels using a large mother substrate, a scribing process for cutting two bonded mother substrates by unit cell is required. The scribe process includes a method of cutting using a laser beam and a method of using a scribe wheel. In a method of cutting a mother substrate using a scribe wheel, the scribe wheel is brought into contact with the mother substrate and then moved along a cutting schedule line to form a scribe line having a groove having a predetermined depth on the surface of the mother substrate. In a method of cutting a mother substrate using a laser beam, a scribe line is formed by irradiating a laser beam along a cutting target line on an upper surface of the mother substrate.
Once the scribing process is complete, a braking process is needed to separate the mother substrate along the scribe line. In general, in the braking process, a braking bar is disposed on an upper surface of a mother substrate on which a scribe line is formed, and then the braking bar is pressed on the mother substrate to apply a physical impact to the mother substrate. The mother substrate propagates the cracks along the scribe line by the physical impact and is separated by unit cells. Substrates separated by unit cells, that is, unit substrates are transferred to the outside.
As such, the braking process separates a portion where the unit cell is not formed, that is, a cullet portion and a portion where the unit cell is formed. However, as the utilization efficiency of the mother substrate and the size of the flat panel display panel gradually increase, the distance between adjacent unit cells is gradually narrowing. In particular, each unit cell is provided with a sealant for coupling two mother substrates disposed up and down. Due to the adhesive component of the sealant and the reduction in the width of the collet part, a breaking failure occurs in which the collet part and the unit cell part are not cut to each other.
An object of the present invention is to provide a conveying unit for a cutting device that can improve the cutting efficiency.
It is also an object of the present invention to provide a cutting device capable of improving cutting efficiency.
It is also an object of the present invention to provide a cutting method using the cutting device described above.
A conveying unit for a cutting device according to one feature for realizing the above object of the present invention comprises a body and at least two receiving portions.
The receiving unit is installed on the rear surface of the body and separates the cutting object having the scribe line formed along the scribe line and receives and transports a specific portion from the cutting object.
Each receiving portion includes an adsorption portion and a pressurizing portion. An adsorption part vacuum-adsorbs the upper surface of the said cutting object. The pressurization part is installed adjacent to the adsorption part, and presses the collet region of the cutting object which is not received by the adsorption part in a braking step of separating the cutting object along the scribe line in a direction opposite to the adsorption direction of the adsorption part. do.
In addition, the cutting device according to one feature for realizing the above object of the present invention comprises a scribing unit and a breaking unit.
The scribing unit forms a scribing line on the surface of the mother substrate assembly to cut the mother substrate assembly to form a plurality of unit panels each forming a flat panel display panel. The braking unit includes a transfer unit which cuts the mother substrate assembly having the scribe line formed along the scribe line, separates each unit panel, and picks up and transfers each unit panel.
In particular, the transfer unit comprises a body and at least two receivers. The receiving part is provided on the back of the body, and has an adsorption part and a pressurizing part. The adsorption unit vacuum-adsorbs the upper surface of the mother substrate assembly. The pressurization unit is installed adjacent to the adsorption unit, and the collet region of the mother substrate assembly positioned outside the cell region forming the unit panel during the braking process of separating the mother substrate assembly along the scribe line. Pressurize in the direction opposite to the adsorption direction.
In addition, the cutting method according to one feature for realizing the above object of the present invention is as follows.
First, a scribe line is formed on the surface of the mother substrate assembly to cut the mother substrate assembly to form a plurality of unit panels each forming a flat panel display panel. The mother substrate assembly in which the scribe line is formed is cut along the scribe line and at the same time, the unit panel is received from the mother substrate assembly and drawn out.
According to the present invention described above, the transfer unit receives the portion to be received from the cutting object while performing the braking step of the cutting object, thereby improving the breaking efficiency and productivity.
