Description

Technical Field

[0001] The present invention relates to the field of automated production assistance technology, in particular to a production assistance device based on an MCU controller. Background Art

[0002] Microcontroller unit, also known as single-chip microcomputer or single-chip microcomputer, is a computer that appropriately reduces the frequency and specifications of the central processor, and integrates memory, counter (Timer), USB, A / D conversion, UART, PLC, DMA and other peripheral interfaces, and even LCD drive circuits on a single chip to form a chip-level computer, which can be used for different combination control for different applications. MCU can be seen in mobile phones, PC peripherals, remote controls, automotive electronics, industrial stepper motors, robot arm control, etc. According to the characteristics of single-chip microcomputers, the application of single-chip microcomputers is divided into single-machine application and multi-machine application. In an application system, only one single-chip microcomputer is used, which is called a single-machine application. The single-machine application range of single-chip microcomputers includes: measurement and control system. Single-chip microcomputers can be used to form various less complex industrial control systems, adaptive control systems, data acquisition systems, etc., to achieve the purpose of measurement and control; intelligent instruments. Using single-chip microcomputers to transform the original measurement and control instruments promotes the development of instruments in the direction of digitalization, intelligence, multi-function, integration, and flexibility.

[0003] The projection technology used in the existing projection positioning tooling solutions is limited by the hardware configuration. Therefore, projection parameters such as projection distance and projection ratio are customized according to the actual application environment, and the projection distance or image size can only be adjusted within a limited range; the machine vision inspection system is susceptible to environmental interference (such as shadows, bright spots, etc.), and has corresponding requirements for the integrated environment. For special application environments, auxiliary components may be added, otherwise it will lead to misjudgment during the inspection process. After searching, it is found that the typical production auxiliary device in the prior art is the production auxiliary system and device based on industrial vision and projection technology, which is published in CN117596374A. The software automatically renders and generates graphics based on the product and process information entered by the user. The projector provides users with the most intuitive graphic experience through a digital interface. In response to the user's operation process, the visual module and the system control module work in coordination to capture the user's working status in real time, and judge whether the operation meets the requirements. The system will quickly and accurately correct the user's erroneous operations. Its main feature is to build a virtual image that conforms to the human cognitive model in accordance with the actual parameters and process requirements of the workpiece by constructing a visual module and a standardized software platform. During the overall use process, the software and the visual module are connected to the system server in real time, and the actual working status of the operator will be fully supervised and guided. It can be used in industrial production and intelligent manufacturing and other applications, so that the system can replace the traditional assembly mode.

[0004] In summary, the projection technology used in existing production auxiliary devices is limited by hardware configuration and software performance, that is, the loading process has a low degree of intelligence, and it is not convenient to quickly adjust the position according to the actual situation, that is, the guidance of the staff. On the other hand, most of the existing production auxiliary devices only have one detection process, which makes it easy for cheating behaviors such as product replacement to occur during the work process. In view of the above problems, it is necessary to improve the existing equipment. Summary of the invention
