Technical Field

[0001] The invention relates to the field of automatic production lines for cutting plates, in particular to an automatic slitting production line for shielding plates. Background Art

[0002] In some nuclear industries and military environments, a multi-layer shielding structure is required for protection. The existing shielding structure uses multiple layers of shielding plates stacked together. Each layer of shielding plates needs to be cut into multiple pieces according to the design size and spliced into an overall plate shape.

The integrity of the cutting seam is inspected. If the cutting is found to be broken, the full-angle suction head of the robotic arm of the robotic arm will suck it to the defective area of the cutting inspection. If the inspection is qualified, the full-angle suction head of the robotic arm of the robotic arm will suck it to the overall thickness inspection platform. The thickness inspection of each small plate raw material is completed by the multi-channel thickness inspection head in the width direction, and classified and screened within the controllable accuracy range. If the thickness accuracy range is exceeded, the full-angle suction head of the robotic arm of the robotic arm will suck it to the defective thickness platform. If the thickness accuracy range is within, it will be placed on the good thickness platform and sucked by the robotic arm robot. The small plate materials are sent to the flip conveyor belt, which transports the small plate materials to the bottom of the flip rack. According to the thickness accuracy error values of the four corners of the small plate materials detected, any small plate materials are selectively sucked by the flip lifting suction head and flipped in the flip rack through the flip cylinder and the flip axis to avoid the problem of excessive error accumulation at the same angle of the small plate materials, which may cause excessive error in subsequent stacking. The flipped small plate materials are sucked by the robotic arm robot and placed on the feeding and coding roller conveyor belt on the flip conveyor belt to complete coding and inkjet coding, and then fed to the cutting feed conveyor belt through the coding roller conveyor belt, and sent to the cutting platform under the suction of the first cutting lifting suction head. On the top, the small plate raw material is fed and positioned and clamped in combination with the front-cutting positioning push plate facing backward and the front-cutting positioning push plates facing forward, and the first lifting cutting saw completes the first cutting of the small plate raw material, and the small plate raw material is divided into two structures of the front long strip part and the rear square part. After the cutting is completed, the positioning and clamping are released, and the two structures are sucked onto the reversing platform by the first cutting lifting suction head, and the rear square part is sucked to the second cutting opening position by the second cutting lifting suction head, and the suction is released until the rotation of 90 degrees is completed at the same time, and the rear square part is clamped between the front-cutting positioning push plate and the rear-cutting positioning push plate in the front-to-back direction, and the second lifting cutting saw completes the cutting on both sides of the square part;Meanwhile, the front long strip part is sucked to the position of the third cutting opening by the second cutting lifting suction head, and is sucked and placed while rotating 90 degrees at the same time. The front long strip part is clamped in the front and rear positioning push plates for saw seam adjustment before and after cutting in the front and rear directions. After cutting off the middle saw seam size on both sides of the square part after cutting off one side in the length direction of the front long strip part, and loosening the clamping, the front long strip part with the cut saw seam size and the rear square part cut into two parts are successively sucked by the second cutting lifting suction head and sent to the trimming conveyor belt. The three pieces are successively sent to the first trimming seat through the trimming conveyor belt to complete trimming of the opposite two sides, and then sent to the trimming transfer conveyor belt, where they are sucked and rotated 90 degrees by the trimming reversing lifting suction head and sent to the second trimming seat to complete trimming of the other two sides. After trimming, they are sucked by the blanking lifting suction head and placed on the blanking access conveyor belt. The two structures of the front long strip part and the rear square part are successively blocked by the positioning and combining baffle on the blanking access conveyor belt and spliced into an integral structure. After the splicing is completed by detecting with the blanking vision detection camera, the three spliced integral structures are sucked at one time by the blanking lifting suction head and placed on the blanking stacking conveyor belt of the stacking lifting seat. The front, rear, left, and right positioning push plates for stacking are combined to reposition and push the three spliced integral structures to be closely spliced. After the stacking lifting seat stacks the three spliced integral structures cut from the same small plate raw material, it descends, and the three spliced integral structures of the next small plate raw material are sent to the front, rear, left, and right positioning push plates for stacking and adaptation docking. After completing multi-layer stacking, the stacking lifting seat drives the blanking stacking conveyor belt to rise to the blanking output conveyor belt and dock, and completes the conveying and blanking output of multi-layer stacking at one time. The overall cutting production has a high degree of automation and high cutting and stacking accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

The front part of the blanking access conveyor belt 110 is connected to the rear part of the second edge trimming seat 90. A positioning combination baffle 111 is erected with a gap above the rear part of the blanking access conveyor belt 110.

The conveying direction of the blanking stacking conveyor belt is on the side opposite to the stacking left and right positioning push plates and is butted against the blanking output conveyor belt 119.

[0059] The large board raw material 1 of this production line is sucked by the feeding lifting suction head 19 of the feeding and screening device 6 and placed on the side thickness detection device 7. The side detection rotating cylinder rotates the side detection frame 27 so that the infrared detection head 28 corresponds to the side of the large board raw material 1, thereby detecting that the side thickness is within the precision range. The unqualified large board raw material 1 is sent out to the defective raw material station 21 through the screening conveyor belt 20. The qualified large board raw material 1 continues to be sucked and sent to the large board cutting device, and is sucked and held by the rotatable negative pressure adsorption large board cutting platform 29. Combined with the front and rear positioning push plates 36 and the left and right positioning push plates 38 of the large board for positioning, the large board cutting saw 32 completes the horizontal and vertical cutting into four equal small board raw materials 2; the cut small board raw materials 2 are sent to the cutting detection platform 40 along the cutting detection conveyor belt 39. The cutting detection vision detection head 41 detects the periphery of the cut small board raw materials 2. The small board raw materials with side collapses detected and screened are sucked and sent out by the robotic arm 10. The qualified ones after detection are sucked and sent to the overall thickness detection table 45. Multiple thickness detection heads 48 move along the thickness detection track with the thickness detection cross beam 47 to detect the overall thickness of the small board raw materials 2. The unqualified ones after detection are sucked and placed on the thickness defective platform 43, and the ones with qualified thickness are sucked and placed on the thickness good product platform 44; the robotic arm sucks the qualified small board raw materials and sends them to the flipping conveyor belt 49. According to the thickness of the four corners and four directions of the overall thickness detection of this board, if the small board raw materials are qualified within the thickness precision range, due to the negative deviation of the single-side thickness, if they are continuously stacked, greater errors will be generated in subsequent stacking, resulting in unqualified stacking and affecting the shielding performance. It is necessary to be transported to the position of the flipping lifting cylinder 50 on the flipping conveyor belt 49, drive the flipping frame 51 to lower the frame. After the flipping lifting suction head 54 sucks and holds the small board raw material, the flipping cylinder 52 drives the flipping lifting suction head 54 to rotate through the flipping shaft 53 to turn the negative deviation side of the small board raw material to the other side, and then the suction head of the robotic arm sucks and places it back on the flipping conveyor belt and is subsequently transported to be connected to the coding roller shaft conveyor belt 55. Control the rising of the coding front and rear positioning brackets 57 to position the rear side of the small board raw material, and combine with the lifting of the coding left and right positioning brackets 59 to lift the left and right positioning columns 60. Driven by the opposite movement of the coding left and right bidirectional cylinder guide rails 61, the small board raw material is centered and positioned in the left and right directions, and the coding and inkjet printer 56 is used for inkjet marking.

[0060] The small plate raw materials after inkjet marking are continuously sent to the lower part of the front end of the cutting row frame 62, sucked by the first cutting lifting suction head 65 and placed at the position of the first cutting opening 68 of the cutting platform 63. The cutting pre-positioning push plate 66 in front of it pushes backward, and the cutting front and rear positioning push plate 70 behind it pushes forward to complete the positioning of the small plate raw materials on the cutting platform. The first lifting cutting saw 69 cuts the small plate raw materials into a front long strip part 3 and a rear square part. After loosening the clamping and positioning, the second cutting lifting suction head 74 sucks and rotates the front long strip part 3 and the rear square part by 90 degrees and places them on the reversing platform 72, then sucks the rear square part and places it on the second cutting opening 76. After the same clamping and positioning, the rear square part is cut into a rear square left part 4 and a rear square right part 5. At the same time, the second cutting lifting suction head 74 sucks the front long strip part 4 and places it on the third cutting opening 79. After the same clamping and positioning, the side of the front long strip part 3 is cut to remove the cutting saw slot dimensions of the rear square left part 4 and the rear square right part 5. After the cutting of the front long strip part 3, the rear square left part 4, and the rear square right part 5 is completed, they are successively sucked and sent to the trimming conveyor belt 85, and the first and second trimming seats 86 and 90 complete the trimming of the opposite two sides and the other two sides in sequence. The trimming is conveyed through the conveying gap 98. At the same time, the knife seat 104 elastically abuts against the side of the plate. The front trimming guide plate 105 and the trimming knife 106 respectively guide and trim the side of the plate at the cutting edge. The trimming stable pressure head 109 corresponds to the trimming position to press the belt above and below the plate to ensure that the plate is not affected by the reaction force during trimming and avoid the problem of the reduction of trimming accuracy caused by the up and down and front and back movement of the plate. The trimmed plate is successively sent to the blanking access conveyor belt 110, and under the suction action of the blanking lifting suction head 114, combined with the positioning combination baffle 111 and the blanking vision detection camera 112, the front long strip part 3, the rear square left part 4, and the rear square right part 5 are completely assembled into the structure of the small plate raw materials (such as Figure 2 ), the blanking lifting suction head 114 completely sucks and places it on the blanking stacking conveyor belt 115, and is pushed and positioned by the stacking front and rear positioning push plates 117 and the stacking left and right positioning push plates 118. After the blanking stacking conveyor belt 115 completes the placement and positioning of a small plate raw material structure on the stacking lifting seat 116, it descends to continue stacking the next small plate raw material structure, so as to successively complete the stacking of multiple small plate raw materials (such as Figure 1 ), after reaching the set stacking layer number, the blanking stacking conveyor belt 115 rises to the height of the blanking output conveyor belt 119 for docking, and the stacked multi-layer small plate raw material structures are output through the blanking output conveyor belt 119.

[0061] In this embodiment, the angle of the cutting saw is adjusted according to the assembly angle of the front long strip part 3, the rear square left part 4, and the rear square right part 5.
