The invention discloses a tile laying device and a tile laying
robot. The tile laying device comprises a knocking mechanism, wherein the knocking mechanism comprises a flexible knocking part, a knocking driving part and an elastic element, the knocking driving part is arranged to be capable of driving the flexible striking part to stretch out and draw back to vertically knocking tiles laid on a to-be-operated surface, and the elastic element is arranged between the knocking driving part and the flexible knocking part and is used for providing elastic
restoring force for the flexible knocking part when the soft striking part is used for knocking the
ceramic tiles. When the striking driving piece of the tile laying device drives the flexible striking piece to knock the tiles, elastic
restoring force is provided for buffering through the elastic element, so that the tiles can be prevented from being knocked and damaged, and the phenomenon of hollowing of the tiles is reduced; and in addition, due to the fact that the flexible striking piece vertically knocks the tiles, the phenomenon that
tangential force is applied to the tiles, so that plane displacement of the tiles is caused is avoided, the
height difference among the tiles can be effectively guaranteed particularly when the tiles are laid on the wall surface, and the tile laying quality is improved.
