I. Background knowledge

The automotive industry is a high-tech industry with a relatively high degree of automation, and many advanced automation technologies have been successfully applied to various production processes in the industry. Many aspects of automobile manufacturing have achieved unmanned operation, which requires a reliable detection technology to verify the correctness of each assembly and the eligibility of assembly parts.

Machine vision is deployed in a variety of industrial and consumer applications to bring efficiency, innovation, and advances in automation. Compared with the traditional detection methods, machine vision detection has a strong ability to adapt to the harsh environment of the industrial production site, has a higher cost performance, universal industrial interface and relatively high fault tolerance and security.Among them, the automotive industry is one of the earliest industries to adopt automated machine vision technology.The application of machine vision technology has run through the whole automobile manufacturing process, including the development from the initial quality inspection of raw materials to the 100% on-line measurement of automobile parts, and then the control of welding, gluing, punching and other processes in the manufacturing process, and finally the quality control of the body assembly and the whole vehicle leaving the factory.

二、Process flow of automobile industry

The production process of automobile is a very complex and huge industrial production, involving many types of workshops and types of work. Briefly speaking, automobile production mainly includes six parts: stamping, welding, painting, power assembly, assembly and testing.

First: Stamping process (producing various body stamping parts)

Second: Welding process (welding various body stamping parts into a finished body)

The third: painting process (to prevent the body from rusting, so that the body has a beautiful appearance)

Fourth: Powertrain process (production and assembly of engine and gearbox through forging)

Fifth: Final assembly process (assemble the body, chassis and interior parts together to form a complete car)

Sixth: Inspection process (potential quality problems in the production and assembly process are found, and unqualified products are rejected as far as possible)
