AR fastener auxiliary assembly system and method based on projection display

Abstract

The invention discloses an AR fastener auxiliary assembly system and method based on projection display. The AR fastener auxiliary assembly system comprises a process database module, an AR intelligent guide module, an assembly detection module and an integrated control module. An abstract assembly guidance process is projected on an assembly operation site in an AR visualization mode, and an assembly result is detected and fed back in real time, so that the cognitive burden of operators is reduced, the assembly efficiency is improved, and the assembly error rate is reduced. According to the system and the method, the complex and abstract fastener assembly process information is subjected to AR visualization through the AR technology of projection display, is seamlessly fused in a physical assembly scene and is briefly and intuitively presented in front of an operator, and the requirements for the cognitive level and experience judgment ability of the assembly operator on the research and reading process are reduced.

Description

technical field [0001] The invention belongs to the field of AR technology, and in particular relates to an AR fastener auxiliary assembly system and method. Background technique [0002] Augmented reality (AR) is an emerging technology that "seamlessly" integrates the real world and the virtual world. In the intelligent manufacturing system, augmented reality technology provides a common way of interaction between man, machine and things, breaking the boundary between virtual objects and the real environment, and integrating people and manufacturing systems. In the manufacturing industry, augmented reality technology has obvious advantages and broad application prospects especially in the field of auxiliary assembly of complex products due to its uniqueness of combining virtual and real. [0003] In the high-end equipment manufacturing industry, the assembly link is an important part of the product life cycle, which is related to the quality, cost and performance of the pr...

AI Technical Summary

Problems solved by technology

However, this assembly process-oriented AR guidance method is suitable for product assembly scenarios where the number of identical parts is small, the structure is complex, there are many constraints, and the assembly sequence is strict. It is not suitable for batch assembly guidance of fasteners.

The fasteners in the same assembly step are completely interchangeable, and there is no strict assembly sequence requirement. The unit is a part group, and the system lacks a detection and feedback link, which causes discontinuity in the assembly process and affects operating efficiency.
