The first motor 12 drives the reciprocating screw rod 11 to rotate, so that the movable frame 13 can move and drive the cutting head 18 to move forward and backward. The second motor 15 drives the first screw thread 14 to rotate, so that the movable block 16 can move under the action of the first screw thread 14 and drive the cutting head 18 to move left and right, so that the cutting head 18 can cut the optical glass;

[0024] A positioning mechanism is provided on the surface of the processing table 1, and the positioning mechanism includes a fixed block 2, which is fixedly connected to the upper surface of the processing table 1, and a forward and reverse screw 21 is movably connected to the inner side of the fixed block 2.

The surface of the movable rod 24 is movably connected to the limit plate 25. The moving block 23 can be driven to move by rotating the forward and reverse screws 21, and then the movable rod 24 can drive the limit plate 25 to move, so as to achieve the effect of positioning the optical glass through the limit plate 25, and can ensure the fixation of the optical glass during cutting, thereby achieving a better cutting effect.

[0025] Furthermore, the positioning mechanism also includes a first rubber pad 26, which is fixedly connected to one end of the limit plate 25 away from the movable rod 24, and the bottom end of the movable block 23 is fixedly connected to the limit block 27.

[0027] Furthermore, one end of the limit block 27 is fixedly connected to the moving block 23, and the other end of the limit block 27 is movably connected to the limit groove 28.

[0028] Furthermore, a pressing mechanism is provided on the surface of the limiting plate 25, and the pressing mechanism includes a connecting block 3, which is fixedly connected to the surface of the limiting plate 25, and the inner side of the connecting block 3 is threadedly connected to a second screw 31, and the bottom end of the second screw 31 is movably connected to a pressing plate 32, and the lower surface of the pressing plate 32 is fixedly connected to a second rubber pad 33, and the surface of the pressing plate 32 is fixedly connected to a slider 34, and a sliding groove 35 is provided on the surface of the limiting plate 25, and the rotation of the second screw 31 can drive the pressing plate 32 to move vertically, so that the pressing plate 32 can be moved downward to press the optical glass, so that the optical glass is more stable during cutting.

[0029] Furthermore, one end of the slider 34 is fixedly connected to the pressure plate 32, and the other end of the slider 34 is movably connected to the slide groove 35. Through the setting of the slider 34 and the slide groove 35, the pressure plate 32 can be limited, so that the pressure plate 32 can move vertically under the action of the second screw 31.

By moving the moving blocks 23 away from each other, the distance between the two groups of limit plates 25 is reduced, and the first rubber pad 26 is in contact with the surface of the optical glass, so that the limit plate 25 can limit the optical glass, and the optical glass can be fixed;

[0031] By rotating the second screw 31, the pressing plate 32 is limited by the slider 34 and the slide groove 35, and will move vertically under the action of the second screw 31, and then the slider 34 slides on the surface of the slide groove 35. By moving the pressing plate 32 downward and making the second rubber pad 33 contact the upper surface of the optical glass, the pressing plate 32 can press the optical glass, making the optical glass more stable during cutting.
