Description

Flexible substrate cutting device {APPARATUS FOR CUTTING FLEXIBLE BOARD}

The present invention relates to a flexible substrate cutting apparatus, and more particularly, to a flexible substrate cutting apparatus capable of precisely cutting a flexible substrate.

Recently, as the electronic display industry has rapidly developed in the semiconductor industry, a flat panel display (FPD) has begun to emerge. In addition, the flat panel display is used as a monitor of a TV or a computer, or a display device of a device such as a mobile phone, a PDA, a digital camera, and the like.

Types of flat panel displays include liquid crystal display (LCD) substrates, plasma display panel (PDP) substrates, field emission display (FED) substrates, and organic light emitting diodes (OLED) substrates.

Conventionally, since a substrate made of a material having brittleness such as glass or the like has been used as a substrate of a flat panel display, the flat panel display itself does not have flexibility.

However, recently, a flat display having flexibility has been developed, and in order to have flexibility, a flat substrate having a flexible material such as plastic must be used.

Meanwhile, in order to manufacture a substrate included in a flat panel display, a substrate having a desired size is manufactured from a substrate by cutting the substrate.

As an example of the conventional substrate manufacturing process, when the base substrate is made of a brittle material such as glass, a scribing device is used to form a scribe line on the base substrate according to the shape of the substrate of a desired size. Thereafter, the substrate was impacted to cut the substrate to a desired size, or the substrate on which the scribe line was formed was heated and cooled to diffuse vertical cracks extending from the scribe line in the vertical direction of the substrate to cut the substrate.

However, in the case of manufacturing a flexible substrate for a flat panel display, since the substrate itself is made of a flexible material, a scribe line is formed on a substrate as in the prior art, and the substrate is impacted to cut or heat and The scribing apparatus to cool and cut | disconnect has a problem that the board | substrate of a desired size cannot be manufactured from a base board.

Therefore, there is a need for research and development on a flexible substrate cutting device having a new structure capable of cutting a flexible substrate to a desired size. In particular, there is a need for a flexible substrate cutting device capable of precisely aligning a flexible substrate with a cutting member for cutting the same, and then precisely cutting the substrate to a desired size continuously.

Referring to the operation of the flexible substrate cutting apparatus according to the present invention configured as described above are as follows.

13 and 14 are plan views schematically illustrating operations of a flexible substrate cutting apparatus according to an embodiment of the present invention.

First, a cutting unit for mounting the base plate 100 to the support plate 310 of the stage unit 300 using a robot or the like and cutting the stage unit 300 using the stage transfer unit 400 ( To 500).

And, as shown in FIG. 13, the vision unit 600 checks whether the alignment mark 130 displayed on the base plate 100 matches the virtual cutting line 150, and if it matches, cuts work. If it does not match, transfer the stage unit 300 in the work line direction using the stage transfer unit 400, or the support plate 310 by using the drive unit 330 of the stage unit 300 By rotating, the alignment mark 130 and the virtual cutting line 150 coincide with each other.

When it is confirmed that the alignment mark 130 and the virtual cutting line 150 coincide with each other, the cutting operation unit 530 operates the cutting member 515 to cut the substrate 100. That is, the stage unit 300 and the base substrate 100 are moved along the work line to cut the base substrate 100 into the plurality of unit substrates 110 in one direction.

Then, in order to cut the substrate 100 cut in one direction again in the direction intersecting the cut direction, as shown in FIG. 14, the support plate 310 is rotated. Then, in the same manner as described above, after confirming the alignment of the alignment mark 130 and the virtual cutting line 150 is aligned, the stage unit 300 and the cut substrate 100 along the work line The substrate 100 is sequentially cut into a plurality of unit substrates 110 by moving.

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.
