Abstract

The embodiment of the invention discloses an automatic rivet feeding system and method based on robot vision, relates to the field of intelligent manufacturing, and can solve the problems that in theprior art, rivets are difficult to take out in a scattered mode, the rivet feeding efficiency is low, and more kinds of rivets cannot be conveyed. An industrial robot, a cover plate assembly, a rivetblowing mechanism, a detection disc, a vacuum generator, a valve group and a rivet storage disc are mounted on a fixture; the multifunctional end effector is composed of a flange plate, a support, anindustrial CCD camera, a laser displacement sensor, a spring, a stirring rod and a vacuum suction nozzle. The multifunctional end effector is connected with the tail end of the industrial robot through a flange plate; the bracket is used for fixing an element on the multifunctional end effector; the industrial CCD camera is installed right in front of the support and used for obtaining rivet images. The laser displacement sensor is installed on the side face of the support and used for measuring the depth of rivets. The vacuum suction nozzle is installed below the support and used for grabbingor putting rivets. The automatic nail feeding device is suitable for automatic rivet feeding in the aircraft manufacturing process.

Description

Technical field [0001] The invention relates to the aviation manufacturing direction in the field of intelligent manufacturing, and in particular to an automatic nail feeding system and method based on robot vision. Background technique [0002] In recent years, with the help of large domestic aircraft projects such as Yun-20 and C919, the domestic aircraft manufacturing industry has been rapidly upgraded. In the design of aircraft, the comprehensive application of MBD (Model Based Definition) technology has basically got rid of the previous paper drawings and the low-efficiency design model of one institute and one institute, and the design of aircraft has reached a world-class level. However, in the manufacturing process, there are still a large number of old equipment and old processes that need to be eliminated or upgraded, and the degree of intelligence and automation needs to be further improved. With the development and development of a new generation of aerospace product...
