Abstract

The embodiment of the invention relates to the technical field of automatic assembly, and discloses a method and device of robot automatic assembly based on multisensor fusion. The invention solves the problemsthatthe positioning range of a system is small, the positioning precision is not accurate and the detection information is incompletein the prior art, according to the technical scheme, thesystem comprises an upper computer system, an industrial robot, a clamping system, a multisensor system and to-be-assembled bodies, wherein the upper computer system is used for acquiring measurementdata of the multisensor system and performing calculation, planning the movement of the robot according to acalculation result and feeding back the movement of the robot to the industrial robot; the industrial robot is used for conveying the to-be-assembled bodies,the clamping system is used for clamping the to-be-assembled bodies,and the multisensor system is used for obtaining the pose relationship and contact force information among the assembly bodies. According to the method and the device, the assembly process is planned according to theaccurate detection of the multisensor fusedmulti-parameter data of the to-be-assembled bodies, so that high-precision automatic assembly of acomplex large body is realized, the system positioning range is expanded, and the positioning precision is improved.

Description

technical field [0001] The invention relates to the technical field of automatic assembly, in particular to a method and device for automatic assembly of a robot based on multi-sensor fusion. Background technique [0002] The robot automatic assembly system is widely used in automobile manufacturing, home appliance production, logistics and warehousing and other fields due to its advantages of high transfer accuracy, long working cycle, good stability, and adaptability to extreme environments.
