Preferably, the mounting module 100 is located below the glass plate G, and can support the glass plate G from the bottom to the top. In such an embodiment, the glass plate G may be seated on top of the mounting module 100.

Here, the mounting module 100 can move the glass plate G mounted thereon. That is, the mounting module 100 can support the glass plate G in a state in which the mounted glass plate G is moved. For example, as shown in FIG. 2, the mounting module 100 may include a plurality of rollers, and a glass plate G may be mounted on the rollers. The mounting module 100 can move the glass plate G mounted on the upper part through the rotation of the rollers in the horizontal direction as indicated by an arrow a in Fig.

As described above, the mounting module 100 may be implemented as a roller so as to move the mounted glass plate G, but the mounting module 100 may move the glass plate G mounted thereon variously. For example, the mounting module 100 has a conveyor belt, and a glass plate G is mounted on the conveyor belt, so that the glass plate G can be moved.

It is needless to say that the mounting module 100 may support the glass plate G while the glass plate G is fixed in place without being moved.

That is, the load applying pin 220 has a contact area smaller than the entire area of the glass plate, and pressure can be applied to a part of the glass plate through movement in the vertical direction as indicated by the direction e1 in the drawing.

In this case, the load can be applied by the load applying pin 220 while the glass plate is not moved and fixed. At this time, the load applying pin 220 can apply a load to various portions of the glass sheet through horizontal movement as indicated by e2 and e3 in the figure. Or the load applying pin 220 moves only in the vertical direction (e1 direction) in a state where the seat is fixed, and a load is applied to various parts of the glass plate by moving the glass plate by the mounting module 100 It is possible.

9 is a view schematically showing a configuration of a glass plate defect detecting apparatus including a load applying module 200 according to another embodiment of the present invention.

10 is a side view schematically showing a configuration of a glass plate defect detection apparatus including a sensing module 300 according to an embodiment of the present invention.

The sensing module 300 senses whether or not there is damage to the glass plate to which the load is applied by the load application module 200. According to the present invention, since a load is applied to the glass plate by the load application module 200, the defective glass plate can be damaged. The sensing module 300 senses the damage when the glass plate is damaged due to the load application of the load application module 200.

Here, the sensing module 300 may include a light emitting unit that emits a light wave of a predetermined wavelength to a glass plate, and a light receiving unit that receives a light wave reflected from the glass plate.

However, the present invention is not necessarily limited to these embodiments, and the sensing module 300 can detect whether the glass plate is damaged in various ways.

Preferably, when the glass plate is damaged by the sensing module 300, the load applying module 200 may be configured to release the load applying operation to the glass plate. For example, if the sensing module 300 senses damage to the glass plate while the load application module 200 is applying a load to the glass plate, such damage detection information is transmitted from the sensing module 300 to the load application module 300. [ (200). Then, the load application module 200 can immediately move away from the glass plate so that no load is applied to the glass plate.

According to this embodiment, it is possible to prevent complete breakage of a defective glass plate, thereby preventing glass plate fragments or the like caused by breakage from adhering to or scattering from the load application module 200. That is, even if the glass plate is damaged due to the load, if the load is continuously applied to the glass plate, the glass plate may be broken, and debris generated during the damage may be adhered to the load application module 200, Other components of the glass or the glass plate may be damaged. Particularly, if the debris or the like attached to the load application module 200 is not removed, the glass plate may be damaged even if the glass plate is free from defects when a load is applied to the next glass plate.
