Intrinsic safety design method for collaborative robot

Abstract

The invention relates to the field of collaborative robots, in particular to an intrinsic safety design method for a collaborative robot. The intrinsic safety design method for the collaborative robot comprises the following steps of: 1, analyzing a working performance of the collaborative robot; 2, designing an upper layer of the collaborative robot; 3, performing risk analysis on the collaborative robot, and determining a safety risk type and a safety evaluation index; 4, performing correlation analysis on the working performance and the safety performance of the robot, and determining indexes having coupling influence on the working performance and the safety performance of the collaborative robot; 5, establishing a man-machine interaction impact model, drawing a human body biomechanics limit index-based danger level safety table, and determining a coupling index parameter range according to the safety table; and 6, according to the coupling index parameter range obtained in the step 5, performing safety design on the basis of the collaborative robot optimized in the step 2. According to the intrinsic safety design method for the collaborative robot provided by the invention, the safety performance indexes and the working performance indexes of the mutually coupled collaborative robots can be balanced and maximized at the same time.

Description

technical field [0001] The invention relates to the field of collaborative robots, in particular to an intrinsically safe design method for collaborative robots. Background technique [0002] Collaborative robots refer to robots that can directly interact with humans in a designated collaborative area. Collaborative robots break through the limitation of human-machine separation, and they share the workspace with humans, which is suitable for human-machine collaborative tasks in unstructured environments and improves the automation level of small and medium-sized enterprises. [0003] Different from traditional industrial robots that pursue maximum performance and work in a closed structure environment, collaborative robots need to seek maximum performance under the constraints of safety, that is, the safety of physical human-computer interaction, and how to achieve collaboration at the same time Maximizing the working performance and safety performance of robots is the dif...

[0003] Different from traditional industrial robots that pursue maximum performance and work in a closed structure environment, collaborative robots need to seek maximum performance under the constraints of safety, that is, the safety of physical human-computer interaction, and how to achieve collaboration at the same time Maximizing the working performance and safety performance of robots is the difficulty in the design of collaborative robots at present. In the existing technology, there are few researches on the safety design of collaborative robots, and most of them only focus on the analysis and evaluation of injury risks and the analysis of influencing factors of physical human-computer interaction.
