Description

Method for cutting glass and cutting device

The present invention relates to a method of cutting glass and a cutting apparatus, and more particularly to a cutting method and a cutting apparatus for cutting a strengthened glass substrate.

At present, glass substrates are widely used in various parts of electronic products, such as screens, touch panels, and housings. In order to prevent the glass substrate from being scratched or easily broken, the glass substrate generally used for electronic products needs to be strengthened. As shown in FIG. 1, the strengthened glass substrate 1 includes a stretched layer 11 and at least one compressive layer 12 formed on the outer side of the stretched layer 11. The tensile layer 11 has a tensile internal stress, and the compression layer 12 has a compressive internal stress. The stress distribution is such that the outer layer of the strengthened glass substrate 1 is not easily broken even if it is subjected to a shallow scratch caused by an external force, but the glass substrate is strengthened. 1 is also difficult to cut, so special tools and equipment are required for cutting. Referring to FIGS. 1 and 2A, in general, the tempered glass substrate 1 has a large size and needs to be cut into a glass product 10 required for various home appliances or electronic products.

A method of cutting a conventional tempered glass substrate 1 is described below. In the first step, the tempered glass substrate 1 is scribed in advance on one of the edges 13 of the tempered glass substrate 1 along a predetermined dicing line 201 as shown in FIG. 2A. Here, the depth of the tempered glass substrate 1 needs to exceed the thickness of the compression layer 12, so that the tempered glass substrate 1 is naturally split into the plurality of sub-substrates 1A due to the tensile internal stress of the tensile layer 11, as shown in FIG. 2B. After the first step, an external force may be applied to bend the strengthened glass substrate 1 to assist in strengthening the splitting of the glass substrate 1 into the plurality of sub-substrates 1A.

In the second step, a predetermined cutting line 202 for cutting the sub-substrate 1A of the tempered glass substrate 1 into a desired size is prepared, which is a predetermined cutting line 202 as shown in FIG. 2B, and is self-reinforcing when actually scribing. A point on the other edge 13 of the sub-substrate 1A of the glass substrate 1 is scored along the arrow toward the predetermined cutting line 202 of the sub-substrate 1A, so that the scribe line will extend along the predetermined plurality of edges of the respective tempered glass products 10, and The shape of the glass product 10 is engraved around.

After the second step described above, as shown in FIG. 2B, the conventional cutting method is characterized in that the tempered glass product 10 is more easily removed, and in the third step, the plurality of predetermined cutting lines 203 are scored on the ear piece 14 to make the ear The material 14 is easily separated into a plurality of pieces for manual splitting. The predetermined cutting line 203 is in contact with the predetermined cutting line 202 and the edge 13.

Similarly, the depth of the sub-substrate 1A in which the tempered glass substrate 1 is scribed also exceeds the thickness of the compression layer 12, so that the sub-substrate 1A of the tempered glass substrate 1 is easily split naturally into a plurality of glass products by the tensile internal stress of the tensile layer 11. , as shown in Figure 2C.

The conventional cutting method scribes the inside of the strengthened glass substrate 1 or the sub-substrate 1A from the edge 13 of the strengthened glass substrate 1 or the sub-substrate 1A. Therefore, when the tempered glass substrate 1 is to be cut into a plurality of glass products 10, the tempered glass substrate 1 is first scribed and cut into the sub-substrate 1A in accordance with the first step. Therefore, time must be wasted in the pre-cutting step that is not directly used to cut the glass product 10. Further, in the second step, the scribe cut must extend from the edge 13 of the sub-substrate 1A along the predetermined cut line 202, and then extend along the plurality of edges of the respective tempered glass products 10. After the second step, the sub-substrate 1A is easily split naturally from the edge 13 along the predetermined cutting line 202, separating the glass product 10 from the plurality of ear pieces 14. After the third step, the sub-substrate 1A is more easily split naturally along the predetermined cutting line 202 and the predetermined cutting line 203, making the glass product 10 easier to separate from the plurality of ear pieces 14.

After the glass product 10 is completely separated from the ear material 14, the relative position of the glass product 10 to the ear material 14 is easily offset, and it is difficult to accurately transport the glass product 10 to the correct destination position using an automated conveying device. Therefore, it is very difficult to carry out automation engineering using conventional methods.

Therefore, how to overcome the conventional method of cutting a tempered glass substrate, which has a long cutting time and is difficult to fully automate, is an important issue in the industry.

It is an object of the present invention to provide a cutting method suitable for cutting a tempered glass substrate to form a plurality of glass products and a cutting apparatus using the same, which can save cutting time and be easier to automate.

To achieve the above object, the cutting method of the present invention comprises the following steps. In the step (a), the tempered glass substrate is scribed along the plurality of first predetermined cutting lines. Each of the first predetermined cutting lines extends along a plurality of edges of the respective glass products and exits all of the predetermined cutting lines on the strengthened glass substrate and the plurality of edges of the strengthened glass substrate. In step (b), the glass product is taken out from the strengthened glass substrate.

To achieve the above object, the cutting apparatus of the present invention comprises a cutting tool and a removal tool. The cutting tool is used to scribe the strengthened glass substrate along a plurality of first predetermined cutting lines. Each of the first predetermined cutting lines extends along a plurality of edges of each of the glass products and exits all of the predetermined cutting lines on the strengthened glass substrate and the plurality of edges of the strengthened glass substrate. The removal tool is used to remove the glass product from the strengthened glass substrate.

First, please refer to the tempered glass substrate 1 of FIG. 1 , which comprises a tensile layer 11 , at least one compression layer 12 formed on the outer side of the tensile layer 11 , and a plurality of edges 13 . Among them, the stretched layer 11 has a tensile internal stress, and the compressed layer 12 has a compressive internal stress.

A first embodiment of the cutting method of the present invention is illustrated in Figures 3A through 3C, which is adapted to cut a tempered glass substrate 1 to form a plurality of glass products 10. As shown in FIG. 3A, the glass product 10 may be arranged on the strengthened glass substrate 1 as a matrix having any number of rows and columns, or may be other arrangements; however, the cutting method of the present invention does not need to be previously The tempered glass substrate 1 is cut into a plurality of sub-substrates 1A to form an edge for cutting an individual glass product 10 (such as a predetermined dicing line 201), and the sub-substrate 1A is cut into a glass product 10.

The first embodiment of the cutting method of the present invention is described in detail below. As shown in FIG. 3A, first, the tempered glass substrate 1 is scribed along a plurality of first predetermined cutting lines 301. Each of the first predetermined cutting lines 301 extends along the plurality of edges of the respective glass products 10 and leaves all of the predetermined cutting lines on the strengthened glass substrate 1 and the edges 13 of the strengthened glass substrate 1. That is, a gap is left between each of the first predetermined cutting lines 301 and the other predetermined cutting lines on all of the strengthened glass substrates 1 and the edges 13 of the strengthened glass substrate 1.

Wherein, the depth of the tempered glass substrate 1 along the first predetermined cutting line 301 is preferably greater than the thickness of the compression layer 12, so that the tempered glass substrate 1 is cut along the first predetermined due to the tensile internal stress of the tensile layer 11. Line 301 naturally splits into a plurality of glass products 10. At this point, however, the split plurality of glass products 10 have not been able to be displaced relative to each other with respect to the ear pieces 14', since the ear pieces 14' are formed to surround the glass product 10 and have an uninterrupted shape.

As shown in FIG. 3A, in order to assist in taking out the glass product 10 from the strengthened glass substrate 1, the cutting method of the present invention can further remove all the first predetermined cutting lines 301 and strengthen the adjacent glass sheets 10 before taking out the glass product 10 from the strengthened glass substrate 1. The plurality of second predetermined cutting lines 302 of the edges 13 of the glass substrate 1 are scribed to strengthen the glass substrate 1. That is, a gap is left between all of the second predetermined cutting lines 302 and all of the first predetermined cutting lines 301 and the edges 13 of the strengthened glass substrate 1.

After the first predetermined cutting line 301 and the second predetermined cutting line 302 are scribed on the strengthened glass substrate 1, since there are no conventional techniques on the plurality of ear materials 14' surrounding the glass product 10 and formed on the strengthened glass substrate 1, The edge 13 of the glass substrate 1 is scored inwardly, so that the ear material 14' and the glass product 10 are not separated from each other, and the glass product 10 is still supported by the ear material 14' and does not leave the strengthened glass substrate 1. Therefore, even if the first predetermined cutting line 301 is scribed on the tempered glass substrate 1, even after the second predetermined cutting line 302 is further scribed, at this time, the reinforced glass substrate 1 is not subjected to the ear material 14' and the glass product 10 Dispersed, it is still suitable for transportation to other process equipment using automated equipment.

Thereafter, the tempered glass substrate 1 scribed along the first predetermined cutting line 301 and the second predetermined cutting line 302 is transported to another place for processing in the next process, that is, the glass product 10 is taken out from the tempered glass substrate 1. Wherein, as shown in FIG. 3B, the second predetermined cutting line 302 facilitates the step of separating the plurality of ear materials 14' formed around the glass product 10 and formed on the strengthened glass substrate 1 in the step of taking out the glass product 10 from the strengthened glass substrate 1. The shape of the ear piece as shown is such that it is easier to remove the glass product 10. The shape of the removed glass product 10 is as shown in Fig. 3C.

Since the tempered glass substrate 1 has high hardness, it is quite difficult to cut.

In one embodiment, the corners of the plurality of glass products 10 cut from the tempered glass substrate 1 are rounded, so that the corners of the first predetermined cutting line 301 are a plurality of rounded corners 301A. In this embodiment, the imaginary line extending in the direction of the second predetermined cutting line 302 may pass through the plurality of centers 301B of the corresponding rounded corners 301A of the first predetermined cutting line 301.

As shown in FIG. 3A, one of the plurality of straight line segments not parallel to the first predetermined cutting line 301 may be defined on the strengthened glass substrate 1 in a first direction 3A and a second direction 3B, and the second predetermined cutting line 302 is parallel to At least one of the first direction 3A and the second direction 3B extends and is distributed between the first predetermined cutting line 301 and the edge 13 of the strengthened glass substrate 1. At this time, the imaginary line extending in the direction of the second predetermined cutting line 302 still passes through the plural center 301B of the adjacent corresponding rounded corner 301A. Therefore, the second predetermined cutting line 302 of the present embodiment forms a complex X shape.

However, in other embodiments, all of the second predetermined cutting lines 302 may extend only parallel to the first direction 3A or the second direction 3B, or the direction of extension thereof does not pass through the corresponding rounded corner 301A of the adjacent first predetermined cutting line 301. The plural center 301B.
