[0040] When the automobile sheet metal mold needs to be deburred, and when the automobile sheet metal mold moves between the surfaces of the four second conveying rollers 9, the two second motors 17 are stopped, and then the first motor 13 is started to rotate the threaded shaft 12. The rotation of the threaded shaft 12 causes the inverted I-shaped slider 11 to move downward, and the downward movement of the inverted I-shaped slider 11 drives the adjustment plate 8, the second conveying roller 9 and the automobile sheet metal mold to move downward; and the downward movement of the second conveying roller 9 drives the first worm gear 15 to move downward, and the downward movement of the first worm gear 15 is separated from the worm 18;

[0042] The rotation of one of the rotating shafts 24 causes the five rotating shafts 24 to rotate synchronously in the same direction through the first sprocket 30, the second sprocket and the chain 31, and finally causes the five rotating shafts 24 to drive the five bearing plates 4 to rotate 180 degrees through the connecting block 25, and finally causes the five bearing plates 4 to flip to the upper part of the grinding groove 3 and combine into a table for placing the automobile sheet metal mold;

[0043] At the same time, the adjustment plate 8, the second conveying roller 9 and the automobile sheet metal mold move downward to the inside of the grinding groove 3, and the second conveying roller 9 moves to the bottom of the carrying plate 4 through the gap between the two adjacent carrying plates 4 through the notch, and the automobile sheet metal mold is blocked between the tops of the carrying plates 4 through the limit of the carrying plates 4;

[0044] By installing a robotic arm at both ends of the top of the device base 1 and installing an electric grinder at the end of the robotic arm, the electric grinder can be driven by the rotation, extension and horizontal adjustment of the robotic arm to perform burr grinding operations on the automobile sheet metal mold on the surface of the supporting plate 4, and the grinding debris will be concentrated on the surface of the supporting plate 4.

[0045] Working principle: by starting the two second motors 17, the two worm gears 18 are rotated, and the rotation of the two worm gears 18 will drive the first worm gear 15 and the second worm gear 16 meshing with them to rotate, so that all the first worm gears 15 and the second worm gears 16 rotate in the same direction, and the first worm gears 15 and the second worm gears 16 rotating in the same direction can effectively convey and move the automobile sheet metal mold, and the rotation of the first worm gear 15 and the second worm gear 16 will drive the second conveying roller 9 and the first conveying roller 7 to rotate, and the second conveying roller 9 and the first conveying roller 7 located at the same horizontal height can process, convey and move the automobile sheet metal mold, thereby improving the convenience of processing, conveying and moving the automobile sheet metal mold.

[0046] When the first conveying roller 7 and the second conveying roller 9 are located at the same height and rotate, they can convey and move the automobile sheet metal mold. At this time, the carrying plate 4 is attached. Figure 2 and Figure 4 As shown in the middle of the grinding groove 3 and in contact with the cleaning roller brush 5, the debris on the carrier plate 4 will fall into the inside of the grinding groove 3, and the debris stuck on the carrier plate 4 will not fall, and the debris on the carrier plate 4 can be cleaned by the reciprocating movement and rotation of the cleaning roller brush 5;

[0047] During cleaning, the first conveying roller 7 and the second conveying roller 9 are located at the same height and rotate to convey and move the automobile sheet metal mold, and the rotation of one of the worm gears 18 drives the first bevel gear 32 to rotate, and the rotation of the first bevel gear 32 will transmit the second bevel gear 34 to drive the first rotating shaft 33 and the third bevel gear 35 to rotate, and the rotation of the third bevel gear 35 will transmit the large bevel gear 37 to drive the second rotating shaft 36 to rotate, and the rotation of the second rotating shaft 36 will drive the two first adjusting arms 38 to rotate, and the rotation of the two first adjusting arms 38 will drive the second adjusting arms 39 to reciprocate, and the reciprocating movement of the two second adjusting arms 39 will drive the two inverted T-shaped sliders 41 to reciprocate inside the two sliding transverse grooves 40, and the reciprocating movement of the two inverted T-shaped sliders 41 will drive the cleaning roller brush 5 to move;

[0048] The movement of the cleaning roller brush 5 will drive the adjusting gear 42 to roll on the surface of the second tooth plate 43 and drive the cleaning roller brush 5 to rotate, so that the cleaning roller brush 5 can rotate during the reciprocating movement. The reciprocating and rotating cleaning roller brush 5 can clean the debris stuck on the supporting plate 4, so that the debris is concentrated in the internal collection box of the collection groove 6 through the grinding groove 3.

[0049] When the automobile sheet metal mold needs to be deburred, and when the automobile sheet metal mold moves between the surfaces of the four second conveying rollers 9, the two second motors 17 are stopped, and then the first motor 13 is started to rotate the threaded shaft 12. The rotation of the threaded shaft 12 causes the inverted I-shaped slider 11 to move downward, and the downward movement of the inverted I-shaped slider 11 drives the adjustment plate 8, the second conveying roller 9 and the automobile sheet metal mold to move downward; and the downward movement of the second conveying roller 9 drives the first worm gear 15 to move downward, and the downward movement of the first worm gear 15 is separated from the worm 18;

[0050] At the same time, the downward movement of the inverted I-shaped slider 11 will also drive the fixed block 19, the vertical plate 20, the first tooth plate 22 and the expansion slot 23 to move downward, and the downward movement of the first tooth plate 22 will cause the first gear 26 to roll and rotate on its surface, and the rotation of the first gear 26 will drive one of the rotating shafts 24 to rotate, so that the block 27 rotates inside the expansion slot 23 and moves up relatively inside the expansion slot 23 and the inverted convex vertical slot 21; when the first gear 26 is separated from the first tooth plate 22, the block 27 rotates 180 degrees and moves up to the inside of the inverted convex vertical slot 21, at which time one side of the block 27 will slide in contact with one side of the inverted convex vertical slot 21, so that the rotating shaft 24 can remain stable and will not rotate;

[0051] The rotation of one of the rotating shafts 24 causes the five rotating shafts 24 to rotate synchronously in the same direction through the first sprocket 30, the second sprocket and the chain 31, and finally causes the five rotating shafts 24 to drive the five bearing plates 4 to rotate 180 degrees through the connecting block 25, and finally causes the five bearing plates 4 to flip to the upper part of the grinding groove 3 and combine into a table for placing the automobile sheet metal mold;

[0052] At the same time, the adjustment plate 8, the second conveying roller 9 and the automobile sheet metal mold move downward to the inside of the grinding groove 3, and the second conveying roller 9 moves to the bottom of the carrying plate 4 through the gap between the two adjacent carrying plates 4 through the notch, and the automobile sheet metal mold is blocked between the tops of the carrying plates 4 through the limit of the carrying plates 4;

[0053] By installing a robotic arm at both ends of the top of the device base 1 and installing an electric grinder at the end of the robotic arm, the electric grinder can be driven by the rotation, extension and horizontal adjustment of the robotic arm to perform burr grinding operations on the automobile sheet metal mold on the surface of the supporting plate 4, and the grinding debris will be concentrated on the surface of the supporting plate 4.

[0054] After the burr grinding operation is completed, the first motor 13 is started in the reverse direction to move the second conveying roller 9 upward to lift and move the processed automobile sheet metal mold on the top of the carrying plate 4 upward, so that the second conveying roller 9 moves upward to be flush with the first conveying roller 7, and then the processed automobile sheet metal mold is conveyed and moved by starting the two second motors 17, and the unprocessed automobile sheet metal mold is conveyed and moved to the second conveying roller 9 at the same time;

[0055] By starting the first motor 13 in reverse, the carrier plate 4 is eventually turned over 180 degrees to face downward, and the cleaning roller brush 5 moves back and forth and rotates to clean the debris on the carrier plate 4 .
