Background
With the development of information technology, electronic products are more and more widely used, and many electronic products have specific shapes, so that the requirement of cutting to form shaped glass is met, and at the moment, the cutting process becomes one of the most critical processes.
Fig. 1 is a schematic diagram of a cutting method provided in the prior art. As shown in fig. 1, after the cutter wheel cuts the first cutting line 110, the cutter wheel decelerates and stops, moves to the start of the second cutting line 120, cuts the second cutting line 120, decelerates and stops, moves to the start of the third cutting line 130, and so on until all the cutting lines are cut. Although the method can avoid the damage of the cutter wheel and the damage of the glass corner, the cutter wheel needs to be frequently lifted and dropped because the end points are not continuous, which seriously influences the cutting efficiency of the glass.
Fig. 2 is a schematic diagram of another cutting method provided by the prior art. As shown in fig. 2, after the first cutting line 110 is cut, the cutter wheel rotates reversely to transit to the second cutting line 120 through an arc 100, and so on until all the cutting lines are cut. Although the method can avoid frequent lifting and falling of the cutter wheel, when the radius of the arc 100 is smaller, the cutting speed needs to be reduced to ensure the cutting quality; when the radius of the arc 100 is large, the occupied area is large, and the arc cannot be applied to glass having a small margin.

Fig. 8 is a flowchart of another cutting method according to an embodiment of the present invention, fig. 9 is a cutting trace of another glass cutting method according to an embodiment of the present invention, referring to fig. 8 and 9, where N is an even number, and the glass cutting method includes:
and S301, cutting the edge of the glass along the edge of the M1 th edge by using a cutter wheel.
And S302, after cutting to the end point of the M1 th edge, cutting to the starting end point of the M2 th edge along the first curve.
And S303, cutting the edge of the glass along the edge of the M2 th edge by using a cutter wheel.
And S304, cutting the edge of the glass along the N-1 th edge by using a cutter wheel.

And S305, cutting to the end point of the (N-1) th edge, and then cutting to the starting end point of the (N) th edge along the second curve.
Wherein, the starting end point of the Nth edge is coincident with the starting end point of the 1 st edge. In this step, referring to fig. 9, for example, after cutting to the end point of the 5 th edge, the 6 th edge 6 is not cut at the end point of the 5 th edge, but the start point of the 6 th edge 6 is set to coincide with the start point of the 1 st edge, and after cutting to the end point of the 5 th edge 5, the 6 th edge 6 is cut along the second curve Q2.
And S306, cutting the glass along the edge of the Nth edge by using a cutter wheel.

That is, the first sub-curve Q21 is tangent to the second sub-curve Q22 at the starting end point of the second sub-curve Q22. In the embodiment of the invention, because the starting endpoint of the Nth edge is arranged at the position which is overlapped with the starting endpoint of the 1 st edge, the cutting direction of the Nth edge is not consistent with the cutting direction of the (N-1) th edge any more, but the cutting direction is reversed, the second curve Q2 comprises the first sub-curve Q21 and the second sub-curve Q22, and the first sub-curve Q21 is tangent to the second sub-curve Q22 at the ending endpoint of the first sub-curve Q21, so that the smoothness of the movement track of the glass cut by the cutter wheel is facilitated when the cutting direction is reversed, and the cutting quality is ensured.

Exemplarily, referring to fig. 4, 9, 11, and 14, the first curve Q1, the second curve Q2, the third curve Q3, and the fourth curve Q4 are tangent to the edge. Therefore, after the edge is cut, when the edge is cut to the first curve Q1, the second curve Q2, the third curve Q3 and the fourth curve Q4, the edge can be smoothly transited to the first curve Q1, the second curve Q2, the third curve Q3 and the fourth curve Q4, and the quality of the cut glass is improved.

Fig. 14 shows a cutting trajectory of another glass cutting method according to an embodiment of the present invention, and referring to fig. 14, in the glass cutting method, a predetermined distance may be further cut along the extension line P1 of the starting end point to the starting end point, and/or a predetermined distance may be cut from the ending end point along the extension line P2 of the ending end point. In other embodiments, if the edge is a curve, the start end point extension line P1 may also be a tangent line of the edge at the start end point. In another embodiment, the end point extension line P2 may be a tangent line of the edge at the end point if the edge is a curve.
Illustratively, referring to fig. 14, before the starting end point of the 1 st edge 1, the glass is cut along the extension line P1 of the starting end point of the 1 st edge 1, and after the glass is cut to the starting end point of the 1 st edge 1, the glass is cut along the trajectory of the 1 st edge 1 to the ending end point of the 1 st edge 1, then the glass is cut along the extension line P2 of the ending end point of the 1 st edge 1, and then the glass is cut along the first curve (curve a1) to the starting end point of the 3 rd edge 3.
In the case where N is an even number, the following may be similarly provided: the start end point is cut by a preset distance along the start end point extension line P1, and/or the end point is cut by a preset distance along the end point extension line P2, which is not limited by the embodiment of the present invention.
Illustratively, referring to FIG. 14, first curve Q1 is tangent to start endpoint extension P1 and end endpoint extension P2. So that the start end point extension line P1 and the end point extension line P2 can smoothly transit to the first curve Q1, thereby improving the quality of cut glass. Based on the same reasoning, when the cutting trajectory includes the start endpoint extension line P1 and the end endpoint extension line P2 in fig. 9, 11 and 14, the second curve Q2, the third curve Q3 and the fourth curve Q4 may be tangent to the start endpoint extension line P1 and the end endpoint extension line P2, so that the start endpoint extension line P1 and the end endpoint extension line P2 may smoothly transit to the second curve Q2, the third curve Q3 and the fourth curve Q4, thereby improving the quality of the cut glass.
