[0035] Among them, the movement of the first transverse rod 110 along the z-axis direction can be driven by a motor, the movement of the second transverse rod 120 along the x-axis direction can be driven by a motor, and the movement of the cutting knife assembly 200 along the y-axis direction can be driven by a motor; they will not be elaborated here.

[0036] The cutting knife assembly 200 includes a longitudinal hanging plate 210, a protective joint 220 and a cutter 230. The longitudinal hanging plate 210 is slidably connected to the slide rail 130 on the second transverse rod 120.

[0045] Further, the width of the annular groove 330 is greater than the width of the cutter 230, so as to ensure the smoothness of the movement of the cutter 230 in the annular groove 330, especially when the cutter 230 moves at the corner of the annular groove 330, the cutter 230 does not touch the inner wall of the annular groove 330.

[0046] Further, the bearing platform 300 further comprises a plurality of air suction holes 340, the plurality of air suction holes 340 are arranged on the center placing plate 310 and the edge annular placing plate 320, and the plurality of air suction holes 340 are used for adsorbing and fixing the glass substrate 410 and the film 420. By arranging the plurality of air suction holes 340, after the glass substrate 410 is placed on the bearing platform 300, air suction treatment is performed on the air suction holes 340, so that the glass substrate 410 can be stably placed on the bearing platform 300 and displacement does not occur during cutting.

[0047] Further, the plurality of air suction holes 340 are equidistantly arranged and arranged in a matrix on the center placing plate 310 and the edge annular placing plate 320.
