The winding action of the roller module will cause the ceramic sheet to be disconnected at the cut, so as to continuously complete the cutting of the ceramic sheet. The half-cutting mechanism in the technical solution can effectively reduce the generation of debris and avoid stress deformation at the cutting end.

[0026] As mentioned above, the roll module includes a winding roll 9, an unwinding roll 10, and a plurality of supporting rolls 11 for supporting the ceramic sheet, wherein the winding roll 9 and the unwinding roll 10 are driven by a servo motor. The winding roll 9 and the unwinding roll 10 are driven by the servo motor.

[0027] The above, such as Figure 1 As shown, the half-cutting tool includes a knife rod 2021 and a disc cutter 2022 rotatably connected to the knife rod 2021. The disc cutter 2022 is used for rolling cutting, which can avoid the heat generated by friction from being concentrated at a fixed position on the disc cutter 2022, thereby increasing the service life of the disc cutter 2022.

[0028] The above, such as Figure 1 As shown, the driving module includes a first servo slide 3 and a second servo slide 4 which are perpendicular to each other, wherein the second servo slide 4 is arranged on a slider on the first servo slide 3, and the half-cutter module is arranged on a slider on the second servo slide 4. The first servo slide 3 can drive the second servo slide 4 and the half-cutter module to move horizontally, and the second servo slide 4 can drive the half-cutter module to move vertically, which can improve the efficiency of cutting pieces and make the direction of cutting pieces more accurate.

[0029] In this embodiment, a suction fixing part 101 connected to a negative pressure air source is provided on the horizontal workbench 1. The suction fixing part 101 includes a plurality of holes arranged in an array and connected to a negative pressure air source.

[0032] Furthermore, two guide shafts 5 are arranged on the horizontal workbench 1 in the horizontal direction, and an open shaft seat 6 is slidably sleeved on each guide shaft 5, and a support shaft 7 is passed through the two open shaft seats 6, and a support plate 8 capable of supporting the ceramic sheet in the horizontal direction is sleeved on the outer periphery of the support shaft 7 seat, such as Figure 1 As shown, the open-type shaft seat 6 is provided with a through hole and a threaded hole passing through its opening. After the bolt passes through the through hole and is screwed to the threaded hole, the force between the open-type shaft seat 6 and the outer periphery of the guide shaft 5 or the support shaft 7 can be strengthened by tightening the bolt, thereby fixing the position of the open-type shaft seat 6 on the guide shaft 5 and fixing the position of the support shaft 7, so that the position of the support plate 8 in the horizontal direction can be adjusted so that the support plate 8 can support the ceramic sheet.

[0033] Working principle: first, place the ceramic sheet on the horizontal workbench 1, and use the limit block 102 to preliminarily limit the position of the ceramic sheet on the horizontal workbench 1, and then connect the negative pressure air source of the suction fixing part 101 to fix the ceramic sheet on the horizontal workbench 1 by vacuum adsorption, and then drive the first servo slide 3 and the second servo slide 4 in coordination to make the half-cutting tool move from one edge of the ceramic sheet to the other edge. The half-cutting tool will leave a scratch of a certain depth on the ceramic sheet, and the PET film tape will not be cut off. It is transmitted through the roller module, and the ceramic sheet is disconnected at the cut of the tool to complete the cutting of the ceramic sheet. The half-cutting mechanism in this technical solution can effectively reduce the generation of debris and avoid stress deformation at the cutting end.
