Abstract
A method and system for automatic assembly of a curved surface part are provided. First, a space coordinate system is established, and a first unit normal vector of the space coordinate system is determined. Then, coordinates of three measurement points on the surface of a curved surface part in the space coordinate system are acquired; and a second unit normal vector to the surface of the curved surface part are determined according to the coordinates of the measurement points. Finally, a rotation angle of the end effector is calculated according to the first unit normal vector and the second unit normal vector; and the end effector is adjusted according to the rotation angle, such that a third unit normal vector of the end effector after adjustment coincides with the second unit normal vector. The method and system enhance the automatic assembly quality of the curved surface part.
