Of course, the rotating adsorption plate 2 can also be rotatably mounted on the mounting frame 6.

[0046] The fixed adsorption plate 1 and the rotating adsorption plate 2 are respectively provided with adsorption structures for adsorbing the sheet. The adsorption structure may be a suction cup provided on the adsorption surface, or may be an adsorption hole provided on the fixed adsorption plate 1 and the rotating adsorption plate 2. Figure 2 As shown, a suction cup 8 is provided on the suction surface of the fixed suction plate 1 and the rotating suction plate 2, and a suction hole is provided that penetrates the fixed suction plate 1 (or the rotating suction plate) and the suction cup 8, and an suction strip 7 is provided on the side away from the suction surface, as shown in FIG. Figure 3 As shown, a gas passage connected to the adsorption hole is provided in the adsorption strip 7 for evacuating air so as to form a negative pressure in the adsorption hole to adsorb the sheet.

[0047] In this embodiment, in order to enable the transmission component 3 to drive the rotating adsorption plate 2 to rotate more stably, preferably, a guide structure for guiding the rotating adsorption plate 2 to rotate is respectively provided between the transmission component 3 and the rotating adsorption plates 2 on both sides.

[0048] Preferably, the guiding structure includes a guide groove 22 and a follower 31 moving along the guide groove 22, the guide groove 22 is arranged on one of the transmission component 3 and the rotating adsorption plate 2, and the follower 31 is arranged on the other of the transmission component 3 and the rotating adsorption plate 2.

[0050] Specifically, the rotating adsorption plate 2 is fixed with a guide block 21 on the side facing away from the adsorption surface, and the guide groove 22 is arranged on the guide block 21.

The rotation angle of the rotating adsorption plate 2 can be adjusted by adjusting the shape or size of the guide groove 22 and the stroke of the transmission component 3.

[0054] Technicians in the relevant technical field can understand that the connection relationship between the transmission component 3 and the rotating adsorption plate 2 is not limited to the connection relationship between the guide groove and the follower in the present embodiment.

The reset spring 9 is preferably a tension spring, one end of which is connected to the rotating adsorption plate 2, and the other end is connected to the mounting frame 6. When the rotating adsorption plate 2 rotates, the tension spring is pulled, and when the driving mechanism 4 drives the transmission component 3 to return to release the rotating adsorption plate 2, the rotating adsorption plate 2 is reset under the action of the tension spring.

[0056] To ensure that the adsorption surfaces of the rotating adsorption plate 2 and the fixed adsorption plate 1 are located in the same horizontal plane after the rotating adsorption plate 2 is reset, Figure 7 As shown, the film breaking device also includes a limiting component 10 disposed between the rotating adsorption plate 2 and the mounting frame 6 for limiting the resetting of the rotating adsorption plate 2.

[0064] The sheet breaking device is configured to break the sheet with the scratches so that the sheet breaks at the scratches.

[0065] In one embodiment of the sheet breaking system provided by the present invention, the conveying device can be a conveyor belt, and the marking device and the sheet breaking device are arranged along the conveying direction of the conveyor belt. When the sheet is conveyed by the conveyor belt, when it reaches the marking station, the marking device marks the sheet, and then when it is conveyed to the sheet breaking station, the sheet breaking device breaks it.

[0066] In another embodiment, the conveying device is a turntable, and the sheet can be rotated on the turntable to a marking station and a sheet breaking station, and the marking and sheet breaking operations are performed in sequence.

[0067] In addition, the conveying device can also be a robot, etc., which conveys the sheets to various workstations for marking and breaking operations.

[0068] In one embodiment, the connection between the lifting mechanism 100 and the sheet breaking device is as follows: Figure 7As shown, the lifting mechanism 100 is a lifting cylinder, the movable end of which is connected to the mounting frame 6, specifically to the horizontal plate 63 of the mounting frame 6, and the cylinder body of the lifting cylinder is connected to the frame, so that the lifting cylinder can drive the sheet breaking device to rise and fall relative to the frame, so that it can move in the direction close to the conveying device and away from the conveying device to pick up and place the sheet.
