Manufacturing industry is an important field of technological innovation and efficiency improvement. "5g + industrial Internet" is an important starting point to promote the digital transformation of manufacturing industry. In recent years, in the field of manufacturing, the application scenario of "5g + industrial Internet" has been expanding, which has greatly promoted the digital transformation of the industry, improved the production efficiency and product quality of enterprises, and injected new momentum into the development of the industry. What if the production equipment fails? Operators can get real-time guidance by wearing 5g + Ar (augmented reality) glasses, collecting on-site video and contacting experts remotely. Do you need manual inspection one by one to ensure product quality? Through the camera installed on the equipment, it can directly detect whether the products have surface defects, and detect the assembly quality at the same time, with high accuracy and fast speed... In the manufacturing field, with the promotion and application of "5g + industrial Internet", the scene of on-site auxiliary assembly, machine vision quality inspection and factory intelligent logistics has been continuously expanded, and the results brought to enterprise production and manufacturing have gradually appeared, It has greatly promoted the digital transformation of the industry. On site auxiliary assembly, accurate and efficient product assembly "Di, di..." in Shandong Qingdao Haier central air conditioning interconnection factory, the equipment failure alarm sounded. Production line leader Zhao Lianhui quickly logged into the system, wore 5g + Ar glasses and was a remote connection technical expert. "What if the red light keeps flashing?" Zhao Lianhui asked. The technical expert looked at the video collected at the glasses end, gave voice guidance in the whole process, cooperated with AR image marking, and successfully eliminated the fault. "In the past, in the process of assembling electronic equipment, if there was a fault, we needed to contact experts and ask them to go to the site for maintenance. The communication efficiency was low and the labor cost was high. During this period, the equipment was shut down and waiting, which would also delay the assembly progress," Zhao Lianhui said. In view of this pain point, Haier proposed 5g + Ar remote cooperation scheme. Relying on 5g network and its own real-time remote cooperation platform, it can realize rapid remote diagnosis and processing of equipment faults and virtual assembly auxiliary guidance without stopping and waiting, which is worry-saving and efficient. "Ar production scenario requires higher network bandwidth and lower network delay, and 5g network just meets the demand," said Yang Weixin, factory manufacturing director. "In recent years, the updating and iteration of electronic equipment products is fast, the components are more precise, and the operation is more difficult. Before assembly, we can only read the guidance video or manual first, and then operate. It takes a lot of time and is prone to errors," Zhao Lianhui said, "Now, after receiving simple training, enterprise employees can go to work quickly. The operation guide is hidden in the glasses. Wear 5g + Ar glasses, and the operation guide will be presented in the form of 3D virtual screen. If you want to inquire about the specific installation steps, just touch the virtual interface with your hand." "After the implementation of 5g + Ar scheme, not only the assembly time is shortened, but also the assembly error rate is reduced and the product quality is optimized." Yang Weixin introduced. With the help of 5g network technology, Haier central air conditioning interconnection factory has completed the application of eight types of AR, AI (artificial intelligence) and other machine vision scenes, and the factory assembly efficiency is improved by 30% and the quality is optimized by 7%. Machine vision quality inspection to ensure production safety and stability In the huge workshop, on the display screen of the control room, the quality data of stator punching used for the magnetic circuit of the generator were fed back in real time, and the staff stared at the data in front of them. Suddenly, a data alarm message that did not meet the quality requirements appeared on the display screen. Then, the staff operated on site, analyzed the causes and adjusted the parameters of the corresponding automatic production machine After a while, the product quality data on the display returns to normal. Dongfang Electric Machinery Co., Ltd., located in Deyang, Sichuan Province, this intelligent workshop in the power generation equipment industry has recently attracted a lot of attention. The so-called stator punching refers to the stator core of large generator, which is an important part of motor magnetic circuit. With the help of "5g + industrial Internet", this intelligent workshop integrates many application scenarios such as machine vision quality inspection, production site monitoring, equipment fault diagnosis and so on. Sitting in a clean and tidy control room, Leng Zhi, the director of Dongfang Electric punching and shearing branch, told reporters: "in the past, we used to run the production line every day to check the production progress. Now all the work in the intelligent workshop is completed by automatic equipment. The employees have changed from high-intensity manual operators to 'commanders' and' supervisors'." "After the unified network management of all equipment on the production line, you can master the equipment and production situation in real time, track and trace, and improve product quality and production process." Leng Zhi said that through the cameras installed on various equipment, it can directly detect whether the stator stamping has surface defects, such as scratches and pits, and can also detect the assembly quality. It has the advantages of high accuracy, high speed and high stability. In the production base of Midea microwave and cleaning division in Shunde District, Foshan, Guangdong, 5g network coverage has been realized indoors and outdoors in the 500000 square meter park. In the final assembly workshop, a "mechanical brain" called programmable logic controller (PLC) will be installed in each process , the operator can send remote control commands to the machine through 5g network, and the rapid assembly of one oven and microwave oven is realized on the automatic production line. On the furnace box assembly line, the AI quality inspection system can complete all steps from high-definition photo shooting, uploading analysis to outputting quality inspection results every two seconds. After the application of 5g + AI quality inspection technology, reminders can be sent at the first time for details such as missing screws. The efficiency of the whole quality inspection process is improved by 7% and the false inspection rate is less than 0.5%. Large bandwidth, wide connection, high speed and low delay... 5g network enables a large amount of data to flow smoothly, and greatly reduces the difficulty of workflow and data connection in various factories, workshops and production lines. Zhou Xiaoling, director of information technology of Midea Group, said: "These massive data are equivalent to a virtual factory. Through big data analysis, we can quickly monitor the abnormal problems in the whole production and deal with them in advance, so as to ensure the safety and stability of production." Intelligent logistics in the plant area can optimize the process and save time and effort In the factory area of Jabil Electronics (Wuxi) Co., Ltd. in Wuxi high tech Zone, Jiangsu Province, piles of electronic raw materials that have just arrived at the factory are arranged in turn and "move forward" orderly on the conveyor belt. Then, the materials enter the "belly" of a machine equipped with a camera device. Their label information - where they come from, how they are made, where they are going, etc. are read out and labeled with the company's unique information label, just like a portable ID card. With the "ID card", electronic raw materials can be warehoused. This process is also intelligent: under the system command, they "transfer" to the conveyor belt once or several times, "take" the "forklift elevator" shuttling in the three-dimensional warehouse and "rest" at their designated positions. This warehousing process is much faster than manual. According to the production plan of the plant, the next day, the blue and white intelligent transporters came to pick up these electronic raw materials to the production workshop. These driverless intelligent transporters are a new generation of products in the 5g application scenario - they do not need tracks, do not lay two-dimensional codes, and accurately locate through central control and triangular positioning methods, so that they can go their own way, do not disturb each other, and can work well Keep a safe distance from obstacles through lidar sensors. When it comes to shipping, intelligent delivery vehicles can show their skills. They connect back and forth between the finished product area and the delivery area according to the designed route, which can not only realize the intelligent delivery of finished products such as first in first out, but also automatically "fork" the standard parts with the same size, specification and packaging into the large truck for packing, saving time and effort. The supporting technologies behind these application scenarios are actually not so complex. Shu Peng, general manager of Jabil electronics, introduced that the plant control center in the plant is the brain, and "5g + industrial Internet" is the skeleton. Using new technologies, it can control and process multi-channel data in real time, so as to improve the quality and efficiency of the plant. In the factory control center, through the large glass window, the reporter saw 16 large screens embedded in one wall of the room. Here, by reading the "identity" information, the whole life cycle from raw materials entering the factory to finished products leaving the factory and after-sales can be effectively tracked. It is reported that after the application of "5g + industrial Internet", in the intelligent logistics link of Jabil electronics, the automatic handling efficiency is increased by 50%, the three-dimensional storage efficiency is increased by 30%, and the efficiency of the whole plant is increased by more than 10%.
