摘要： A stiffener composite charge placement system (1100) is presented. The stiffener composite charge placement system comprises a longitudinal end effector (1104) having a first attachment point and a second attachment point; a first rotational arm (1108) having a first connector configured to connect to the first attachment point; a first movement system configured to move the first rotational arm within a manufacturing environment; a second rotational arm (1110) having a second connector configured to connect to the second attachment point; and a second movement system configured to move the second rotational arm within the manufacturing environment.

摘要： Systems and methods are provided for facilitating pick and placement of preforms. One aspect is a method for picking and placing a preform. The method includes placing an inner surface of a first caul plate into contact with a first side of a stringer preform, such that an outer surface of the first caul plate forms a first plane that is uniform along a length of the stringer preform, placing an inner surface of a second caul plate into contact with a second side of the stringer preform, such that an outer surface of the second caul plate forms a second plane that is parallel to the first plane along a length of the stringer preform, grasping the caul plates at the first plane and the second plane along the length of the stringer preform, and lifting the stringer preform together with the caul plates while maintaining the grasp.
