The invention discloses a labeling machine which comprises an attaching production line and a jig return line. The attaching production line and the jig return line are arranged in a two-layer mode, lifting material tables are arranged at the two ends of the attaching production line and the jig return line for transferring conveyed jigs, more than one labeling station is arranged along the attaching production line, labeling devices are installed at all the stations, and all the labeling devices on the production line cooperate to complete the operation of labeling mobile shells. By means of the cooperation of the labeling devices on the production line, and labeling operation of auxiliary materials such as foam gum of the mobile shells can be completed at a time, each labeling device integrates the functions of label stripping and labeling, operation on two products can be conducted at a time, label stripping plates move forwards and backwards through stepping motors, and stability is good. The labeling machine has the advantages of being small in occupied area, high in precision, easy to operate, high in efficiency and the like.
