Description

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 multiple pieces are not spliced ​​by gluing, but directly matched and placed. The processing and production of multiple pieces in each layer of the overall plate-shaped shielding plate is time-consuming and labor-intensive, and they need to be spliced ​​and stacked in sequence later.

The integrity of the cutting seam is inspected. If the cutting is broken, the full-angle suction head of the robotic arm robot 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 robot will suck it to the overall thickness inspection platform. The thickness inspection of each small plate raw material is completed through the multi-channel thickness inspection head in the width direction, and classified and screened within the controllable accuracy range. If the thickness exceeds the accuracy range, the full-angle suction head of the robotic arm robot will suck it to the defective thickness platform.

The small plate raw materials are sent to the flip conveyor belt, and the flip conveyor belt transports the small plate raw materials to the bottom of the flip frame. According to the thickness accuracy error values ​​of the four corners of the small plate raw material thickness detection, any small plate raw material is selectively sucked by the flip lifting suction head and flipped in the flip frame through the flip cylinder and the flip axis to avoid the problem of excessive error accumulation at the same angle of the small plate raw materials, which will cause the subsequent stacking error to be too large. The flipped small plate raw materials are sucked by the mechanical arm robot and placed on the feeding and coding roller conveyor belt on the flip conveyor belt to complete the coding and spraying, 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.

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 in the front-to-back direction between the front-to-back cutting positioning push plate and the rear cutting positioning push plate, and the second lifting cutting saw completes the cutting of the two sides of the square part;At the same time, the front long strip part is sucked to the third cutting opening position by the second cutting lifting suction head, sucked and placed until it is rotated 90 degrees at the same time, and the front long strip part is clamped in the front and rear directions between the front and rear positioning push plates for saw seam adjustment and cutting, and one side of the front long strip part in the length direction is cut to remove the middle saw seam size of the two sides of the rear square part. After loosening the clamping, the front long strip part with the cut seam size and the rear square part cut into two parts are sucked and sent to the trimming conveyor belt by the second cutting lifting suction head in turn, and the three pieces are sent to the first trimming seat in turn through the trimming conveyor belt to complete the trimming of the opposite sides, and then sent to the trimming transfer conveyor belt, where the trimming reversing lifting suction head is sucked and rotated 90 degrees, and sent to the second trimming seat to complete the trimming of the other two sides. After the trimming is completed, the front strip part is sucked and placed on the unloading access conveyor belt by the unloading lifting suction head. The two structures of the long strip part and the rear square part are blocked by the positioning combination baffle on the unloading access conveyor belt and spliced ​​into an integral structure in turn. After the unloading visual inspection camera detects the splicing, the three spliced ​​integral structures are sucked together at one time to the unloading stacking conveyor belt of the stacking lifting seat through the unloading lifting suction head. The front and rear, left and right positioning push plates are combined to position the three spliced ​​integral structures again and push them tightly. After the three spliced ​​integral structures cut from the same small plate raw material are stacked, the stacking lifting seat descends, and the three spliced ​​integral structures for the next small plate raw material are sent to the stacking adapter to connect the front and rear, left and right positioning push plates. After completing the multi-layer stacking, the stacking lifting seat drives the unloading stacking conveyor belt to rise to the unloading output conveyor belt and dock, completing the conveying and unloading output of multi-layer stacking at one time. The overall cutting production has a high degree of automation, and the cutting and stacking precision is high. ; BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The large plate raw material 1 of this production line is sucked by the feeding lifting suction head 19 of the feeding 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 plate raw material 1, so as to detect that the side thickness is within the accuracy range. Unqualified large plate raw materials 1 are sent to the defective raw material station 21 through the screening conveyor belt 20. Qualified large plate raw materials 1 continue to be sucked and sent to the large plate cutting device, and are sucked by the large plate cutting platform 29 that can be rotated and negatively adsorbed. Combined with the large plate front and rear positioning push plate 36 and the large plate The left and right positioning push plates 38 are positioned, and the large board cutting saw 32 completes the horizontal and vertical cutting into four 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, and the cutting detection visual detection head 41 detects the periphery of the cut small board raw materials 2. The broken side edges of the inspection and screening are sucked out by the robot arm robot 10, and the qualified ones 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 beam 47 to inspect the overall thickness of the small board raw materials 2. The unqualified ones are sucked and placed on the thickness defective platform 43, and the qualified ones are sucked and placed on the thickness good platform 44; the robot arm sucks the qualified small plate raw materials and sends them to the flip conveyor belt 49, and the four corners and four directions of the overall thickness of the plate are tested. If the qualified small plate raw materials are within the thickness accuracy range, due to the negative deviation of the thickness on one side, if they are stacked continuously, the subsequent stacking will produce a greater error and lead to unqualified stacking, which affects the shielding performance. It needs to be transported to the flip lifting cylinder 50 position on the flip conveyor belt 49, drive the flip frame 51 to go down the shelf, and flip the lifting suction head 54. After sucking in the small plate raw material, the flip cylinder 52 drives the flip lifting suction head 54 to rotate through the flip shaft 53 to turn the negative deviation side of the small plate raw material to the other side, and then the suction head of the mechanical arm robot sucks it back and puts it back into the flip conveyor belt for subsequent transportation to the coding roller conveyor belt 55 for connection. The front and rear positioning brackets 57 for coding are controlled to rise and position the rear side of the small plate raw material.

The front cutting positioning push plate 66 pushes it backward, and the rear cutting positioning push plate 70 pushes it forward to complete the positioning of the small plate material on the cutting platform. The first lifting cutting saw 69 cuts the small plate material into the front long strip part 3 and the rear square part. After the clamping positioning is released, the second cutting lifting suction head 74 sucks the front long strip portion 3 and the rear square portion and rotates them 90 degrees and then places them on the reversing platform 72, then sucks the rear square portion and places it on the second cutting opening 76, and after clamping and positioning, cuts the rear square portion into a rear square left side portion 4 and a rear square right side portion 5. At the same time, the second cutting lifting suction head 74 sucks the front long strip portion 4 and places it on the third cutting opening 79, and after clamping and positioning, cuts the side of the front long strip portion 3 to remove the rear square left side portion 4 and the rear square right side portion 5 and cuts the saw seam size. After the front long strip portion 3, the rear square left side portion 4, and the rear square right side portion 5 are cut, they are sucked and sent to the trimming conveyor belt 85 in sequence, and the trimming of the opposite sides and the other two sides is completed in sequence through the first and second trimming seats 86 and 90.

The front trimming introduction plate 105 and the trimming knife 106 correspond to the side edge introduction and edge trimming of the plate respectively, and the trimming stabilizing press head 109 is combined to press the upper and lower belts of the plate corresponding to the trimming position to ensure that the plate is not affected by the reaction force during trimming, and to avoid the problem of the plate moving up and down and forward and backward, which reduces the trimming accuracy. The trimmed plates are sent to the unloading conveyor belt 110 in sequence, and under the suction action of the unloading lifting suction head 114, combined with the positioning combination baffle 111 and the unloading visual detection camera 112, the front long strip portion 3, the rear square left side portion 4, and the rear square right side portion 5 are completely assembled into the structure of the small plate raw material (such as Figure 2 ), the unloading lifting suction head 114 completely sucks and unloads the material onto the 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. The unloading stacking conveyor belt 115 completes the placement of a small plate raw material structure on the stacking lifting seat 116, and after positioning, it descends to continue to stack the next small plate raw material structure, thereby completing the stacking of multiple small plate raw materials in sequence (such as Figure 1 ), after reaching the set number of stacking layers, the unloading stacking conveyor belt 115 rises to the height of the unloading output conveyor belt 119 to dock with it, and the completed stacked multi-layer small plate raw material structure is output through the unloading output conveyor belt 119.
