High-precision intelligent scanning system

The invention relates to the field of scanning equipment, in particular to a high-precision intelligent scanning system. The system comprises a supporting base, a first lifting mechanism is arranged on the supporting base, a scanning mechanism is arranged on the lower surface of the first lifting mechanism, and a second lifting mechanism is arranged in the scanning mechanism. A second threaded sleeve can be driven to rotate through a driving motor, the second threaded sleeve is matched with a second threaded rod to drive a fixing base to ascend and descend, meanwhile, the fixing base can drivea rotating rod to rotate through matching of a rack and a transmission gear, and when the rotating rod rotates, a lead screw can be driven to rotate through transmission between bevel gears; and thescrew rod is matched with the screw rod nut to control the opening of the baffle plate, so that the scanning range of the scanner can be controlled, characters with different sizes can be scanned moreconveniently, the scanned
