The invention discloses an intelligent label printing and pasting all-in-one machine. The intelligent label printing and pasting all-in-one machine comprises an intelligent electronic label reader-writer device and a full-automatic visual scanning and labeling device. The intelligent label reader-writer device comprises a first adsorption part, a label supply part to be pasted, a first feeding boxbody and a control unit. A spray gun for spraying glue to the bottom of a label is arranged on the bottom of the first feeding box body, and the control unit controls the first adsorption part to suck and discharge and move the label. The full-automatic visual scanning and labeling device comprises a second adsorption part, a transportation platform, and a sensor for detecting materials on the transportation platform. The control unit controls the second adsorption part adsorb the label sprayed with glue from the intelligent label reader-writer device, and controls the angle and the moving position of the adsorption surface of the second adsorption part to rotate. The intelligent label printing and pasting all-in-one machine has the advantages that the automation degree of the whole process of the work of the intelligent label printing and pasting all-in-one machine is high, and the error rate is effectively reduced.
