System integration of industrial robots is an important part of integrating industrial robot ontology into downstream application scenarios. The industrial robot system integrator provides application solutions for downstream end customers, and is responsible for the secondary development of industrial robot applications and the integration of peripheral automation supporting equipment. Compared with industrial robot body manufacturers, industrial robot system integrators also need to have product design capabilities, process understanding of end customer application needs, relevant project experience in the application industry, etc., and provide standardized and personalized complete sets of equipment that can adapt to different application fields.

There are mainly three modes of industrial robot integration: Japan, Europe and the United States. In the Japanese model, the industrial robot ontology and integration are completely separated. The manufacturer of the industrial robot ontology is only responsible for manufacturing the industrial robot ontology, and its subsidiaries or social engineering companies conduct system integration; The European model is that the manufacturing and integration of industrial robots are completed by ontology manufacturers; The American model is that industrial robot companies purchase brand industrial robots, conduct system integration by themselves, and deliver them to downstream customers. At present, China's industrial robot industry is closer to the U.S. model. We purchase industrial robot machines from abroad, and develop solutions that meet production needs according to the needs of different industries or customers. The business form is mainly based on large-scale projects (integration of key equipment production lines, such as industrial robot work island) and the transformation of the factory production line, upgrading and networking of existing equipment, and providing system design, complete system, equipment integration, EPC engineering and other services in industrial control, transmission, communication, production and management information. This is mainly because the first two modes require manufacturers of industrial robots to occupy a large share of the market.
