Research on Arm of an Improved Palletizing Robot with Parallel Four-bar Linkage

Objective: to study the mechanical properties of the arm structure of palletizing robot with parallel four-bar linkage, and whether it can meet the requirements of higher and higher load and motion speed of palletizing robot in automatic packaging production line. Methods: in this paper, the arm structure of parallel four-bar palletizing robot is analyzed, and its strength is simulated by ANSYS finite element analysis software. Results: the stress nephogram of forearm and rear arm was obtained, the maximum stress value of forearm was 38.4mpa, the maximum displacement was 0.9mm, the maximum stress value of rear arm was 10.7Mpa, the maximum displacement was 0.02mm. Conclusion: the maximum deformation and maximum stress of the forearm and the rear boom can meet the design requirements through the cloud image analysis, which proves that the parallel four-bar arm structure can meet the large bearing capacity, which provides a theoretical basis for the design of the arm structure of the palletizing robot.
