Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a glass cutting device for cutting two laminated glass plates.

[0002]

[Prior art]

 For example, in a liquid crystal cell, two glass substrates each having a transparent electrode formed on the opposite surface are pasted together with a sealing material, and liquid crystal is sealed between both glass substrates inside the sealing material. There is. In such a liquid crystal cell manufacturing method, for example, two relatively large glass plates for forming a plurality of glass substrates are prepared, and a predetermined process such as a transparent electrode forming process or a sealing material forming process is performed. After passing through the pre-process, the two glass plates are bonded together, and the two bonded glass plates are cut before or after the liquid crystal injection process, thereby manufacturing a plurality of liquid crystal cells. There is a way.

By the way, in a conventional glass cutting device for cutting two glass plates that have been bonded together, first, a scribing part is used to scratch the surface of one of the two glass plates located above. Insert a scribe line, then flip the two glass plates upside down by the reversing part, and then, by the impact part, one of the two glass plates located on the upper side of the two glass plates located on the lower side to the surface side. A glass plate is given an impact, which causes one of the glass plates to be cut along the scribe line, and then the moving part moves the two glass plates, followed by another scribe part, an inversion part, and an impact part. By doing so, the other glass plate is cut along the scribe line.

[0004]

[Problems to be solved by the device]

 However, in such a conventional glass cutting device, a total of two processing lines including a scribing part, a reversing part, and an impacting part are separately arranged on both sides of the moving part, so that an installation space is required. There was a problem that not only the size increased, but also the equipment cost increased. An object of the present invention is to provide a glass cutting device that can reduce the installation space and the facility cost.

Next, the moving table 6 is further moved rightward in FIG. 1 by a predetermined distance, and the two glass plates 11 are positioned at predetermined positions of the impact portion 5, as shown in FIG. Then, the impact part 5 is activated at a predetermined timing, and the piston rod 22a of the cylinder 22 is projected, so that the resin cylindrical rod 24 provided on the lower end surface of the impact member 23 causes one of the two glass plates 11 to An impact is applied from the surface side of the other glass plate located on the upper side to one glass plate located on the lower side, whereby one of the two glass plates 11 located on the lower side is marked with a marking line. Cut along. After this, the piston rod 22a of the cylinder 22 retracts. When there are a plurality of marking lines, the moving table 6 is intermittently moved rightward in FIG. 1 by a predetermined distance, and while the moving table 6 is stopped, a shock is applied to the two moving sheets. One of the glass plates located below the glass plate 11 will be cut along the scribe line.

Next, the moving table 6 is moved leftward in FIG. 1 by a predetermined distance to position the two glass plates 11 at predetermined positions on the scribing section 4.
