Problems solved by technology

In the existing studies related to the balance of the disassembly line, there have been many multi-objective optimizations of the disassembly line with a fixed disassembly time, but these optimization processes are not equivalent to the actual manufacturing process, and the existing research has not considered the operator's participation in the disassembly process. The effect of line balance

Embodiment

[0112] The disassembly process of a certain type of coupling is analyzed and explained. The example contains 37 disassembly tasks. For these disassembly tasks, the disassembly tasks are classified according to the scheme shown in step 1), and the classification decision tree is as follows figure 2 shown.

[0113] figure 2 The tool condition 1 in means that the tools used can be disassembled manually or by robots. Tool condition 2 means that disassembly can only be done using robotic tools. Accuracy condition 1 indicates that the accuracy required for the disassembly task is relatively low, and accuracy condition 2 indicates that the accuracy required for the disassembly task is relatively high, and an operator is required to disassemble. Weight condition 1 means that the weight of the components involved in the disassembly task is small, and both humans and robots can be selected. Weight condition 2 indicates that the weight of the component is relatively large, requirin...

Abstract

The invention discloses a man-machine cooperation disassembly line balance optimization method based on a safety guarantee strategy. The method comprises the following steps of: 1) establishing a disassembly task classification model for disassembly tasks on a disassembly line according to attribute characteristics of the disassembly tasks, 2) establishing a disassembly task allocation scheme based on a safety guarantee strategy according to a classification result of the disassembly task classification model and a distance between a person and a robot disassembly operation point, 3) establishing a man-machine cooperation disassembly line optimization model taking the minimum disassembly idle time, the maximum demand index and the minimum disassembly cost as targets, and 4) solving a multi-objective optimization model to obtain a relatively optimal disassembly task allocation scheme and a relatively optimal disassembly task sequence. In combination with the disassembly task classification model, the safety of operators is ensured to the greatest extent, and the disassembly cost is minimized while the shortest disassembly time is ensured.

Description

technical field [0001] The invention relates to intelligent manufacturing technology, in particular to a method for optimizing the balance of a man-machine cooperative disassembly line based on a safety assurance strategy. Background technique [0002] Dismantling end-of-life products is an important step in remanufacturing. Compared with manual disassembly of scrapped products, the disassembly of robots has higher disassembly efficiency and stability than manual disassembly, but it lacks flexibility for scrapped products with different component structures. In the human-machine collaborative disassembly line, humans and industrial robots in each disassembly workstation cooperate to complete the disassembly task. Combining the characteristics of industrial robot disassembly and manual disassembly, the disassembly efficiency of human-machine cooperation is high and the flexibility of disassembly is not lacking. [0003] In the human-machine collaborative dismantling line, in...
