The invention discloses an assembly line structure for drying platy stones. The assembly line structure comprises a material track for transferring stones and also comprises an electric heating body (3), wherein the center of the electric heating body (3) is a hollow channel (4); the middle section of the material track is placed in the hollow channel (4); a heating wire is arranged on the inner wall of the electric heating body (3); a plate overturning mechanism is arranged at the input end of the material track for supporting stone plates; a plate overturning mechanism is also arranged at the output end of the material track for unloading the stone plates; a leaning rack (1) is arranged one side of the plate overturning mechanism; and a plurality of transfer rollers (6) are arranged on the material track. The plate overturning mechanisms are used for supporting the to-be-dried stone plates before the stone plates are dried and unloading the stone plates after the stone plates are dried; the stone plates need not to be unloaded manually, so that that the assembly line is simple to operation; in addition, when the stone plate is dried, the whole stone plate is located in the hollowchannel of the electric heating body, and the four surfaces of the stone plate can be dried at the same time, so that the drying efficiency is high.
