The operating principle of the object scanning device in the present embodiment is as follows:

assuming that fig. 4 is the paper taking and placing device 8 in an initial state, when scanning is needed, a batch of paper to be scanned is arranged in order and then vertically stacked on the taking part conveyor belt 910, and then the reversing motor forwards drives the pressing cam 817 and the positioning cam 816 to rotate forwards (the positions of the two cams are staggered), because two pulleys 814 are arranged at two corners of the triangular disc 818, the positions of the two pulleys 814 are also staggered, and can always be in sliding contact with the edges of the pressing cam 817 and the positioning cam 816, respectively, under the rotation of the pressing cam 817 and the positioning cam 816, the triangular disc 818 also rotates forwards at an angle of 30 degrees, so that the rotating main rod 88 rotates forwards, the rotating range only needs 30 degrees to complete one reversing action of the paper taking and placing device 8, the rotating main rod 88 forwards drives the rotating auxiliary rod 87 to rotate forwards, the rotating auxiliary rod 87 forwards pulls the rotating middle block 86, and the middle block 86 rotates to pull the overturning sliding rod 83 and the power-assisted main rod 85 to rotate forwards, and simultaneously under the matching action of the auxiliary traction rod 89, the main traction rod 810 hinged on the auxiliary power rod 811 and the overturning rod 819, the overturning sliding rod 83 rotates forwards by 90 degrees around the rotating block 84, so that the positioning plate 820 can rotate forwards by 90 degrees, and the telescopic rod 82 and the suction cup 81 are driven to rotate forwards by 90 degrees, and simultaneously along with the forward rotation of the overturning sliding rod 83, the whole suction cup 81 mechanism can be moved to the position above the part taking conveyor belt 910 of the part taking conveyor mechanism, at the moment, the suction cup 81 is perpendicular to the part taking conveyor belt 910, then the telescopic rod 82 stretches out to drive the suction cup 81 to move to one piece of the outermost paper to be scanned on the part taking conveyor belt 910, the suction cup 81 adsorbs the paper to be scanned, then.

The reversing motor reversely rotates to drive the

positioning cams

817 and 816 to reversely rotate, the triangular disc 818 is also reversely rotated at an angle of 30 degrees through the action of the two pulleys 814, thereby causing the rotation master rod 88 to rotate reversely, driving the rotation slave rod 87 to rotate reversely, the reverse rotation of the rotation slave rod 87 pulls the rotation intermediate block 86 to rotate reversely, the turning middle block 86 pulls the turning sliding rod 83 and the power-assisted main rod 85 to rotate reversely, and simultaneously, under the matching action of the auxiliary pulling rod 89, the main pulling rod 810 and the turning rod 819 which are hinged on the auxiliary power-assisted rod 811, the turning sliding rod 83 rotates reversely by 90 degrees around the turning block 84, so that the positioning plate 820 can be rotated reversely by 90 degrees, thereby drive telescopic link 82 and sucking disc 81 reversal 90, simultaneously along with the reversal of upset slide bar 83, also can be with whole sucking disc 81 mechanism move to the transparent board 42 of placing of scanning region on, sucking disc 81 and transparent board 42 of placing are parallel this moment, as the initial condition of fig. 4 promptly. When the positioning plate 820 rotates reversely by 90 °, after the telescopic rod 82 extends to the paper to be scanned on the suction cup 81 and contacts the transparent placing plate 42, the suction cup 81 stops sucking, and after the sucked paper to be scanned is loosened to the transparent placing plate 42, the telescopic rod 82 retracts to start scanning the paper to be scanned on the transparent placing plate 42.

Then the first motor 45 drives the gear 44 to rotate forward, the gear 44 and the rack 43 are meshed for transmission, the transparent placing plate 42 enters a scanning area along the conveying guide rail 41, after the transparent placing plate enters the scanning area, the paper to be scanned on the transparent placing plate 42 is just positioned between the upper scanning probe 11 and the lower scanning probe 12, and then the upper scanning probe 11 and the lower scanning probe 12 start to perform non-contact scanning on the front and back sides of the paper to be scanned; after the scanning is finished, the upper scanning probe 11 and the lower scanning probe 12 stop scanning, the first motor 45 drives the gear 44 to rotate reversely, the gear 44 is meshed with the rack 43, and the transparent placing plate 42 moves out of the scanning area along the conveying guide rail 41.

The switching push rod 92 is then extended to move the placing conveyor and the pickup conveyor upward as a whole, and stops when the placing base plate 93 moves to the position where the pickup base plate 97 was located before.

Then, in the same manner as above, the paper taking and placing device 8 absorbs the scanned paper on the transparent placing plate 42 by the suction cup 81, vertically moves the paper above the placing conveyor belt 94 and between the side baffles 96 on both sides, and then the suction cup 81 stops absorbing and then extends and pushes down the paper by controlling the telescopic rod 82, so that the paper is tiled on the placing conveyor belt 94 and conveyed out by the placing conveyor belt 94.

Then the switching push rod 92 is shortened, the placing and conveying mechanism and the picking conveying mechanism are integrally moved downwards, the whole process is stopped when the picking bottom plate 97 moves to the position of the placing bottom plate 93 before, then the telescopic rod 82 is extended, meanwhile, after the sucking disc 81 opens the paper to be scanned which is adsorbed on the picking conveying belt 910 and is positioned at the forefront between the picking side baffles 91 at the two sides, the paper is transmitted to the transparent placing plate 42 in the same way for the second scanning.

When the extension length of the telescopic rod 82 is not enough to enable the suction cup 81 to suck the paper to be scanned on the pickup conveyor belt 910, the pickup conveyor belt 910 can convey the paper to be scanned on the pickup conveyor belt 910 for a certain distance forward.

When the sucking disc 81 adsorbs and takes out the paper to be scanned on the pickup conveyor belt 910, the page shifting sheets 99 on the inner walls of the pickup side baffles 91 on the two sides can disperse the paper to be scanned adsorbed together, so as to prevent the paper from being adsorbed more than two sheets at one time, and when the paper to be scanned is moved out from the inlet ends of the pickup side baffles 91 on the two sides, the pickup stoppers 98 on the two sides can block the paper to be scanned behind, so as to prevent the paper from inclining forwards and falling down. When the scanned paper moves into the side baffles 96 from the inlet ends of the side baffles 96, the correcting blocks 95 at the two sides can adjust the directions of the two sides of the scanned paper, so that the scanned paper is always in a state of being right side up when being pushed down by the telescopic rod 82 to the conveyor belt 94.

Aiming at old or wrinkled paper, the scanning rendering lamp 13 can be turned on through the controller in the scanning process to adjust different brightness and light positions, so that the problems of old, wrinkling and the like are solved, and the scanning effect is better.
