[0038] Working principle:

[0039] During operation, the laminating return line suction plate machine 1 sucks the laminating plate to be disassembled onto the transmission device 2, and the transmission device 2 transports the laminating plate to be disassembled into the cutting device 3.

[0040] The cutting device 3 can adjust the distance between the cutting worktables 32 through the cross slide 324 according to the layout spacing of the laminating plate.

[0041] When the laminating plate to be disassembled is transported to the cutting working range of the cutter 331, the electric roller 322 of the cutting worktable 32 retracts into the cutting worktable 32 through the air jack 323, and the laminating plate is fixed by the anti-slip pads on the surface of the cover plate 321 of the cutting worktable 32 and the anti-slip pads of the fixing plate 332. After the cutter 331 completes the cutting work through the telescopic movement of the first cylinder 334, the waste copper foil at the edge of the laminating plate falls into the waste collection box 34. The electric roller 322 of the cutting worktable 32 extends through the air jack 323, and the electric roller 322 transports the laminating plate to the conveyor 42 of the plate receiving device 4, thereby effectively completing the cutting and conveying of the materials, further reducing the use of manual labor, and making the equipment more convenient during cutting.

[0042] The moving suction plate device 43 of the plate receiving device 4 sucks the laminating plate on the conveyor 42 through the suction cup holder 436. After the suction cup holder 436 of the moving suction plate device 43 sucks the laminating plate, it moves above the temporary storage table 5 and places the laminating plate on the bearing table 54. After the materials are cut, the various parts in the equipment cooperate with each other, enabling the equipment to form an integrated cutting, thereby further reducing artificial damage, making the quality of the materials higher and the cutting efficiency faster during the cutting process, and further improving the practicability and convenience of the equipment.
