Method of controlling the coating thickness at the painting robots

摘要

PROBLEM TO BE SOLVED: To provide a method for controlling a coating film thickness by which the film thickness at an overlap part of the coatings is optimized in the coating by a coating robot. ;SOLUTION: The arm of a coating robot is moved in a specified direction, and a coating material is sprayed from a spray nozzle provided at the tip of the arm in accordance with a film thickness profile expressed by a quadratic function when overlap coating is conducted while the direction is sifted to a direction orthogonal to the coating direction by a specified distance, the coating is performed with the overlap width W at the overlap part T₃ at which the value obtained by substracting the minimum thickness from the maximum thickness among the thickness UP in the center of the one film thickness profile F₁, the thickness UQ in the profile F₁ corresponding to the edge of the other film thickness profile F₂ and the total thickness UR of both profiles at the crossing between the profiles F₁ and F₂ is minimized.;COPYRIGHT: (C)1999,JPO
