However, in the liquid crystal panel dividing line 900 described above with reference to FIGS. 45 to 54, since the liquid crystal mother panel 908 must be scribed and broken for each side, the processing time becomes long and the installation area of the device also increases. There is a problem of doing.

Further, since it is necessary to invert the liquid crystal mother panel 908 after scribing, there is a problem that the alignment of the liquid crystal mother panel 908 is required again.

Furthermore, two glass substrates are used so that the fragment 916 generated when the A-side substrate 910 is divided by the break device 902 is not left behind or falls during transportation and causes line trouble. An adhesive seal 915 for bonding must be provided between the two glass substrates. Therefore, there is a problem that extra man-hours are required to manufacture the liquid crystal mother panel 908 itself, and the cost of the liquid crystal mother panel 908 increases because the amount of the sealing material used increases.

The scribe device 950 described above with reference to FIG. 55 requires a separate break device for dividing the liquid crystal mother panel 908 scribed by the scribe device 950, and further, the liquid crystal mother panel 908 scribed by the scribe device 950. There is a problem that a reversing device that inverts and supplies the break device is required separately.<patcit num="1"><text>Japanese Unexamined Patent Publication No. 9-278473</text></patcit>

The scribe portion 103 is moved along a direction perpendicular to the paper surface so as not to get in the way, and is not shown in FIGS. 10 to 13.

Referring to FIG. 11, the catcher 32 grips one end of the liquid crystal mother panel 8. Then, the cutter wheel tip 104 scribes the glass substrate 10A along the scheduled scribe line S4.

Referring to FIG. 12, the catcher 32 releases one end of the liquid crystal mother panel 8 and retracts rearward, which is the right direction in FIG. The suction pad 37 provided in the capture mechanism 31 sucks the fragment 64 separated from the liquid crystal mother panel 8 along the scheduled scribe line S2 by the cutter wheel tip 104.

Referring to FIG. 13, the suction pad 37 sucking the piece 64 moves upward or backward, which is the right direction in FIG. In this way, the cutter wheel tip 104 removes the fragment 64 separated from the liquid crystal mother panel 8.

Next, the operation of scribing the scribing lines S3, S4, and S5 in the region 62 shown in FIG. 5 will be described. Referring to FIG. 14, the suction pad 25 of the suction transfer mechanism 2 is a liquid crystal mother so that a preset scribe line S5 on the liquid crystal mother panel 8 is located between the cutter wheel tip 104 and the cutter wheel tip 105.

With reference to FIG. 1 again, the conveyor 15 conveys and positions the liquid crystal mother panel 8A mounted by the catcher 32 to the downstream positioning position. The rotary table 16 rotates the liquid crystal mother panel 8A positioned at the positioning position by 90 degrees. The liquid crystal panel dividing device 1A divides the liquid crystal mother panel 8A into the liquid crystal panel 9 by the same operation as the operation of the liquid crystal panel dividing device 1 described above. The liquid crystal panel 9 divided by the liquid crystal panel dividing device 1A is carried out to the product stock 18 by the material removing robot 17.

Although a liquid crystal panel has been described as an example of a bonded brittle material substrate in which two brittle material substrates are bonded together, the present invention is not limited to this. For example, the present invention is also applied to a flat display panel such as a plasma display panel or an organic EL display panel in which glass substrates are bonded to each other, and a semiconductor substrate in which a glass substrate is bonded to a silicon substrate, a sapphire substrate, or the like. Can be done. The same applies to the second and third embodiments described later.

Further, an example is shown in which the liquid crystal panel dividing device 1 divides the liquid crystal mother panel 8A separated from the liquid crystal mother panel 8 into the liquid crystal panel 9, but the present invention is not limited to this. The liquid crystal mother panel 8A separated from the liquid crystal mother panel 8 by the liquid crystal panel dividing device 1 may be conveyed to the liquid crystal injection device in the next step by the capture mechanism 31.

Further, an example is shown in which the liquid crystal panel 8 divided by the liquid crystal panel dividing device 1A is carried out to the product stock, but the catcher 31A provided in the liquid crystal panel dividing device 1A conveys the divided liquid crystal panel 8 to the inspection device, the liquid crystal injection device, etc. You may.
