[0044] A clamping mechanism 60 is also provided between the punching device 30 and the bending device 40 to prevent the front end sheet material from rotating with the clamping rotating member 41. The clamping mechanism 60 is arranged on the first frame 71 close to the punching device 30. The clamping mechanism 60 includes pneumatic fingers, and the two fingers of the pneumatic fingers are respectively equipped with a first clamping jaw 61 and a second clamping jaw 62.

[0045] The cutting device 50 includes a cutting blade 51 disposed on the second frame 72. The cutting blade 51 is connected to a sixth driving mechanism for driving the cutting blade 51 to move. The sixth driving mechanism may be, but is not limited to, a cylinder.

[0046] The main workbench 70 is also provided with a transport robot 80 for transporting the cut finished products to a set position.

[0047] Working principle:

[0048] Loading: Stack the long strips of sheet materials in bundles on the bottom frame 111 of the loading rack 11, then the movable column 113 pushes the sheet materials close to the fixed column 112, the movable rack 16 moves and absorbs the top sheet materials to the roller 14 of the loading workbench 2 through the suction cup 161, the initial position of the chuck 15 is located at the end of the loading workbench 12, when the sheet materials are on the roller 4, the roller 4 drives the sheet materials to be transported forward, and when one end of the sheet materials exceeds the first movable seat 7 and the second movable seat 8, the first movable seat 16 moves. The movable seat 7 and the second movable seat 8 move closer to the middle so that the first vertical conveyor 71 and the second vertical conveyor roller 81 are close to the sheet material, which corrects the position of the sheet material and prevents the long sheet material from swinging when the chuck 5 drives the sheet material forward. Then the chuck 5 approaches the sheet material and clamps the other end of the long sheet material. During the movement of the chuck 15, the lifting frame 13 closest to the chuck 15 drives the roller 14 to descend. In this way, the lifting frame 13 descends in turn, which can support the sheet material while avoiding the chuck 15.

[0049] Laser printing and punching: The sheet material is conveyed to the conveying roller on the first frame 71. The laser printing device on the first frame 71 prints and marks at the set position. When punching is required, the pressing roller 32 descends to press the sheet material, and then the punching device 30 punches the sheet material.

[0050] Bending and cutting: The feeding mechanism at the front end guides the sheet material from the guide member 46 and passes it through the opened clamping rotating member 41 to the top of the lifting plate 42. In the initial state, the clamping rotating member 41 is in a horizontal state, and there is a certain distance between the second frame 72 and the third frame 73, and the lifting plate 42 is in a lowered state. When the plate is bent, the clamping mechanism 60 clamps the plate, and the lifting plate 42 rises. When flat bending is required, the holding rotating member 41 does not rotate, and then the inner rotating plate 421 rotates, so that one of the first roller 441 and the second roller 442 is close to the plate as a support, and then the outer rotating plate 422 rotates, and the bending plate driving roller 43 drives the plate to rotate; when vertical bending is required, the holding rotating member 41 rotates, and in the present invention, it rotates 90 degrees to make the plate vertical, and then the lifting plate 42 rises and the limiting groove 45 is aligned with the plate so that the plate is stuck in the limiting groove 45, and then the outer rotating plate 422 rotates, and the bending plate driving roller 43 drives the plate to rotate, and the first fulcrum 451 and the second fulcrum 452 are distributed on both sides of the limiting groove 45. The fulcrum on whichever side is rotated serves as the support point. Each time bending begins or ends, the lifting plate 42 rises or descends in coordination, and the lifting plate 42 rotates left or right accordingly during bending. When each bending is completed, the clamping mechanism 60 releases, the holding rotating member 41 holds the sheet material, and the second frame 72 moves a distance toward the third frame 73, so that the holding rotating member 41 holds the sheet material and feeds it relative to the lifting plate 42 a distance. The clamping mechanism 60 then clamps again to proceed to the next bending stage. After all bending is completed, the holding rotating member 41 drives the sheet material back to a horizontal state, and the cutting blade 51 of the second frame 72 cuts the product.

[0051] Arrangement: The third frame 73 returns to the initial position, and the transport robot 80 transports the products to a specific position and arranges them.

[0052] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
