S3. Surface processing step, it comprises following two steps:

S3-1. The curved surface processing tool 22 moves from the first position p1 along the edge of the glass 6 past the second side 62 to the second position p2 (the path of the tool 22 is S1), and cuts off the curved surface The set depth and a set width of the edge of the glass 6 that the processing tool 22 passes through, the first position p1 is located at the first side 61 and is close to the second side 62, and the second position p2 is located at the third side side 63 and close to the second side 62;

S3-2. The curved surface processing tool 22 rises from the second position p2 by a set height and moves a set distance to the third position p3, and the curved surface processing tool 22 moves along the glass 6 from the third position p3. The edge moves to the fourth position p4 through the second side 62 (the path that the tool 22 passes is S2), and cuts off the set depth and the first set depth of the edge of the glass 6 that the curved surface processing tool 22 passes through. The third position p3 is located on the third side 63 and is closer to the fourth side 64 than the second position p2, and the fourth position p4 is located on the first side 61 and is closer to the fourth side than the first position p1 For the fourth side 64, the value of the set height is the same as the value of the set depth.

Afterwards, the curved surface processing tool 22 rises to a set height from the fourth position, and moves a set distance toward the inside of the glass to reach the next position, and then passes the second side 62 along the edge of the glass 6 to the third side 63 for cutting. The width of the glass is set, and the cycle is repeated, and the curved surface processing tool 22 is continuously raised. At one corner of the glass (near the second position p2), the position of the curved surface processing tool 22 is constantly approaching the inner side of the glass 6 until the curved surface The processing tool 22 reaches a certain position pn located on the fourth side 64, and the curved surface processing tool 22 passes through the second side 62 from this position to another position pn+1 opposite to this position of the fourth side 64. During the process, the fourth side A set width of 64 glass is also cut.

S4. The cutter shaft 5 drives the fourth cutter 4 to move upward to the second set height, and drives the fourth cutter 4 to cut a groove 641 at the fourth side 64 of the glass 6;

S5. The cutter shaft 5 drives the third cutter 3 to move down to the third set height, and drives the side of the third cutter 3 to move against the wall of the groove 641 to cut off the third part of the glass. set the width of the glass;

S6. The cutter shaft 5 drives the first cutter 1 to move down to the fourth set height, and drives the side of the first cutter 1 to stick to the edge of the glass 6 except the wall of the groove 641 Moving to cut off a fourth set width of glass of said glass 6 .

S7. Paste the baffle 642 on the upper surface 67 or the lower surface of the glass near the fourth side 64 (the other surface opposite to the upper surface 67), and the baffle 642 protrudes from the groove 641 ; Then, the polishing device polishes the edge of the glass 6, so that the walls of the groove 641 will not be polished by the polishing device to cause chipping.
