断される。Conventionally, when only one plate glass of a liquid crystal cell formed by laminating two plate glasses is broken,
As shown in FIG. 5A, first, a score line 105 is formed on the surface of the sheet glass 102 to be broken among the two sheet glasses 101 and 102 constituting the liquid crystal cell 100. Next, the liquid crystal cell 100 is turned so that the surface on which the score line 105 is formed faces downward.
Is mounted on the mounting table 110 via the rubber sheet 111.
Then, as shown in FIG. 5B, a pressing bar 115 is pressed against the upper surface of the plate glass 101 corresponding to the score line 105 and pressed downward, and the plate glass 1 is passed through the plate glass 101.
02 is pressed downward. Then, the sheet glass 102 is curved so as to protrude downward, and the score line 105 is forcibly opened, thereby generating a crack 105 extending from the score line 105 toward the inner surface of the sheet glass 102. The crack 105a extends to the inner surface of the glass sheet 102, thereby breaking the glass sheet 102.

Inevitably, the sheet glass 101 is also curved. For this reason,
When the transparent electrode is formed on the inner surface of the plate glass 101 like the liquid crystal cell 100, there is a possibility that the transparent electrode may be adversely affected.

A linear concave groove 11 is formed on the upper surface (installation surface) 10a of the zero. The width of the concave groove 11 is wider than the engraved line 105. In particular, when the liquid crystal cell 100 is placed on the upper surface 10a, a predetermined range (allowing the bending deformation necessary for breaking is allowed) on both sides of the engraved line 105 of the plate glass 102.

The depth of the concave groove 11 is such that even when a member corresponding to the concave groove 11 of the glass sheet 102 is bent downward when the glass sheet 102 is broken, the portion does not contact the bottom surface of the concave groove 11. Dimensions are set. Although the length of the concave groove 11 is appropriately set according to the length of the score line 105, as is apparent from FIG. 2, it is set slightly shorter than the width of the sheet glass 102 to be broken.

As will be described later, a vacuum suction device 20 is connected to the vacuum suction hole 15.
Thereby, the inside of the concave groove 11 is vacuum-suctioned through the vacuum suction hole 15 and the vacuum suction groove 14.

The suction source pipe 18 is connected to a large-capacity vacuum tank (vacuum source) 19 via a second electromagnetic valve (open / close valve) V2. The internal volume of the vacuum tank 19 is set to be much larger than the internal volume of the concave groove 11 so that the inside of the concave groove 11 can be instantaneously evacuated to a high degree of vacuum. In addition, the vacuum tank 19 is always maintained at a high degree of vacuum by a vacuum pump (not shown). The first and second electromagnetic valves V1, V2 are alternately opened and closed by a valve control device (not shown).

00 is mounted on the upper surface 10 a of the mounting table 10 via the O-ring 13. In this case, the positioning is performed such that the score line 105 formed in the sheet glass 102 is located at the center in the width direction of the concave groove 11 and is parallel to the concave groove 11.

０２の両側部も確実に破断される。In this state, the first electromagnetic valve V1 and the second electromagnetic valve V2 are repeatedly opened and closed alternately in a short cycle by the valve control device. When the second electromagnetic valve V2 is opened with the first electromagnetic valve V1 closed, the inside of the concave groove 11 is vacuum-sucked by the vacuum tank 19. Then
Due to the negative pressure in the concave groove 11, a portion of the plate glass 102 facing the concave groove 11 is pulled downward, and is curved so as to protrude downward around the portion where the score line 105 is formed. As a result, the score line 105 is forcibly opened, and the score line 1 is opened.
Cracks extending from 05 toward the inner surface of the sheet glass 102 occur. On the other hand, when the second electromagnetic valve V2 is closed and the first electromagnetic valve V1 is opened, the atmosphere is introduced into the concave groove 11, and the sheet glass 102 returns to the original flat state.
By repeating this, a force for breaking acts on the glass sheet 102 in a vibrating manner, whereby the glass sheet 102 is broken from the score line 105. Although both sides of the sheet glass 102 are separated from the groove 11, the engraved line 15
The cracks generated from the portion of the plate glass facing the concave groove 11 extend toward both ends of the scored line 15, so that the plate glass 1
02 are also reliably broken.

ることができる。In the above-mentioned breaking device B1, a negative pressure is applied only to the sheet glass 102 to be broken.
The breaking force hardly acts on the sheet glass 101. Therefore, the glass sheet 102 can be easily broken. Further, since the breaking force hardly acts on the sheet glass 101, even if a transparent electrode or the like is formed on the inner surface of the sheet glass 101, there is no adverse effect on it. In particular, this breaking device B1
Then, the inside of the concave groove 11 is instantaneously vacuum-evacuated to a high degree of vacuum by a large-capacity vacuum tank 19, so that the
02 can be instantaneously applied with a shocking suction force, and the adverse effect on the sheet glass 101 can be almost completely eliminated.

In the above embodiment, the mounting table 10 is installed with the upper surface 10a facing upward, but the upper surface 10a may be oriented in any direction. In addition, although the case where one of the liquid crystal cells 100 including the two glass sheets 101 and 102 is broken is shown, it is needless to say that the single glass sheet can be broken. Further, the shape and size of the concave groove 11 are not limited to the above-described embodiment, but are desirably changed as appropriate according to the shape of the target glass sheet, the length of the score line, and the like. Further, the vacuum suction in the concave groove 11 and the introduction into the atmosphere are alternately repeated. However, when the thickness of the sheet glass 102 to be broken is small, or when the depth of the score line 105 is deep, It is also possible to rupture sufficiently by only one vacuum suction, and in such a case, it is unnecessary to introduce the atmosphere into the concave groove 11. In other words, by repeatedly applying a negative pressure to the glass sheet 102 as described above, a thick glass sheet or a thin glass sheet having a small score line can be easily broken. Further, by connecting the concave groove 11 to a high-pressure tank filled with a pressurized gas, a negative pressure and a positive pressure may be applied to the plate glass 102 alternately.
