The invention discloses a method for automatically adjusting a plastering thicknessand a plastering
robot. The method comprises the steps of S1, establishing a reference
laser surface parallel to a wall surface of a wall; S2, respectively setting a
light sensing device and a push-pull linkage device on the left and right ends of a plastering
machine head; S3,defining a
light spot initial positionof each
light sensing device; S4, conducting real-time collection of the
light spot real-time position of the
light sensing device in the operation process of the plastering
machine head; S5, calculating the deviation data between the real-time position of each
light spot and the initial position of eachlight spot; S6, converting the deviation data into posture adjustment data of the plastering
machine head; S7, according to the posture adjustment data, controlling the push-pull linkage device to adjust the posture of the plastering machine head, so that the plastering machine head and the reference
laser surface are kept parallel; the method can achieve the plastering machine head real-time dynamic adjustment, do not need manual intervention, be capable of automatic calculation of the thickness, have short adjustment time and high precision, can greatly improve the efficiency of construction work, and effectively ensure the thickness of the plastering and the flatness of the working wall surface.
