Technological application achievements continue to emerge, helping the digital transformation of manufacturing industry, focusing on "5G + Industrial Internet"

Manufacturing is an important area of ​​technological innovation and efficiency improvement, and "5G + Industrial Internet" is an important starting point to promote the digital transformation of manufacturing. In recent years, in the manufacturing field, the application scenarios of "5G + Industrial Internet" have been continuously expanded, 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 should I do if the production equipment fails? Operators put on 5G+AR (augmented reality) glasses, capture live video, and remotely contact experts for real-time guidance. Do you need to manually check one by one to ensure product quality? Through the camera installed on the equipment, it can directly detect whether the product has surface defects, and at the same time detect the assembly quality, with high accuracy and fast speed... In the manufacturing field, with the promotion and application of "5G + Industrial Internet", on-site assisted assembly, machine vision Scenarios such as quality inspection and intelligent logistics in the factory area have been continuously expanded, and the results brought by the production and manufacturing of enterprises have gradually emerged, which has greatly promoted the digital transformation of the industry.
On-site auxiliary assembly, product assembly is accurate and efficient
"Di, di..." At the Haier central air-conditioning interconnection factory in Qingdao, Shandong, the equipment failure alarm sounded. Zhao Lianhui, the head of the production line, quickly logged into the system, put on 5G+AR glasses, and remotely connected a technical expert. "What should I do if the red indicator light keeps flashing?" Zhao Lianhui asked. The technical experts watched the video collected by the glasses, gave voice guidance throughout the process, and cooperated with AR image markers to successfully eliminate 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 come to the site for maintenance. The communication efficiency is low and the labor cost is high. During this period, the equipment will be shut down and waiting, and the assembly progress will be delayed." Zhao Lianhui said . In response to this pain point, Haier proposed a 5G+AR remote collaboration solution, relying on the 5G network and its own real-time remote collaboration platform, to achieve rapid remote diagnosis and processing of equipment failures, virtual assembly assistance guidance, without downtime and waiting, worry-free and efficient. "AR production scenarios require higher network bandwidth and lower network latency, and the 5G network just meets the requirements." said Yang Weixin, director of factory manufacturing.
"In recent years, electronic equipment products have been updated and iterated quickly, the components are more precise, and the operation is more difficult. Before doing assembly, we could only watch the instruction video or manual first, and then operate it, which takes a lot of time and is prone to errors. Zhao Lianhui said, "Nowadays, after receiving simple training, the employees of the enterprise can start work quickly. The operation guide is hidden in the glasses. Wearing the 5G+AR glasses, the operation guide will be presented in front of the eyes in the form of a 3D virtual screen. If you want to check the details The installation steps, just touch the virtual interface with your hand.”
"After the implementation of the 5G+AR solution, it not only shortens the assembly time, but also reduces the assembly error rate and optimizes product quality." Yang Weixin introduced. With the help of 5G network technology, Haier's central air-conditioning interconnected factory has completed the application of 8 types of AR, AI (artificial intelligence) and other machine vision scenarios, increasing factory assembly efficiency by 30% and optimizing quality 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 real-time feedback of the quality data of each stator punching piece used for the magnetic circuit of the generator, and the staff are staring at the various data in front of them. Suddenly, a data alarm message that does not meet the quality requirements appears on the display. Immediately, the staff operated on-site, analyzed the reasons, and adjusted various parameters of the corresponding automated production machines. After a while, the product quality data on the display returned to normal.
In Dongfang Electric Co., Ltd. located in Deyang, Sichuan, this intelligent workshop in the power generation equipment industry has recently attracted the attention of many people. The so-called stator punch refers to the stator core of a large generator, which is an important part of the magnetic circuit of the motor. With the help of "5G + Industrial Internet", this intelligent workshop integrates multiple application scenarios such as machine vision quality inspection, production site monitoring, and equipment fault diagnosis. Sitting in the clean and tidy control room, Leng Zhi, director of the punching and shearing branch of Dongfang Motor, told reporters: "In the past, I ran the production line every day to check the production progress. Now all the work in the intelligent workshop is completed by automated equipment. of manual operators transformed into 'commanders' and 'supervisors'."
"After the unified network management of all equipment on the production line, the equipment and production conditions can be grasped in real time, and the product quality and production process can be tracked and traced to improve product quality and production process." Leng Zhi said that through the cameras installed on each equipment, it is possible to directly detect whether the stator punching is not. There are surface defects, such as scratches, pits, etc., and it can also detect the quality of the assembly, which has the advantages of high accuracy, fast speed, and high stability. In the production base of Midea Microwave and Cleaning Division in Shunde District, Foshan, Guangdong, the 500,000-square-meter park has achieved 5G network coverage both indoors and outdoors. In the assembly workshop, a "mechanical brain" called a programmable logic controller (PLC) will be installed on each process. The operator can remotely control the machine through the 5G network, and ovens and microwave ovens are on the automated production line. Fast assembly is achieved.
On the furnace box assembly line, the AI ​​quality inspection system can complete all steps from taking high-definition photos, uploading and analyzing to outputting quality inspection results every two seconds. After the application of 5G+AI quality inspection technology, even the smallest details such as missing screws can be reminded immediately. The efficiency of the entire quality inspection process is increased by 7%, and the false detection rate is less than 0.5%. Large bandwidth, wide connection, high speed, low latency... 5G networks enable the smooth flow of large amounts of data, greatly reducing the difficulty of workflow and data connection in factories, workshops, and production lines. Zhou Xiaoling, director of information technology at Midea Group, said: "These massive amounts of data are equivalent to a virtual factory. Through big data analysis, abnormal problems in the entire production can be quickly monitored and processed in advance to ensure the safety and stability of production."
Intelligent logistics in the factory area, optimizing the process to save time and effort
In the factory area of ​​Jabil Electronics (Wuxi) Co., Ltd. in Wuxi High-tech Zone, Jiangsu, stacks of electronic raw materials that have just arrived at the factory are arranged one after another, and they "walk forward" in an orderly manner on the conveyor belt. Subsequently, the material enters a machine "belly" equipped with a camera device. Their label information—where they came from, how they were made, where they’re going, etc.—was all read out, and each was labeled with the company’s unique information, like an ID card to carry around. With the "ID card", electronic raw materials can be put into storage. This process is also smart: under the system's instructions, they "transfer" the conveyor belt once or several times, "ride" the "forklift elevator" that shuttles through the three-dimensional warehouse, and come to their designated positions to "rest". This warehousing process is much faster than manual labor.
According to the production plan of the factory, the next day, blue and white smart delivery vehicles will pick up these electronic raw materials to the production workshop. These unmanned intelligent transport vehicles are a new generation of products in the 5G application scenario - no need for tracks, no QR codes, and precise positioning through central control and triangulation methods to achieve their own way without disturbing each other. It can also maintain a safe distance from obstacles through lidar sensors.
When it comes to shipping, smart delivery vehicles can also show their talents. They connect back and forth between the finished product area and the outgoing area according to the designed route, which can not only realize the intelligent outgoing of finished products such as FIFO, but also automatically “fork” the standard goods with the same size, specification and packaging into the warehouse. Packing in large trucks saves time and effort. The supporting technologies behind these application scenarios are actually not that complicated. According to Shu Peng, general manager of Jabil Electronics, the factory control center located in the factory area is the brain, and the "5G + Industrial Internet" is the skeleton. Using new technologies, it can control and process multiple data channels in real time, and achieve a double improvement in the quality and efficiency of the factory area.
In the factory control center, through the large glass windows, the reporter saw 16 large screens inlaid on one wall of the room. Here, by reading the "identity" information, the entire life cycle from the entry of raw materials to the delivery of finished products, and after-sales can be effectively tracked. According to reports, after the application of "5G + Industrial Internet", in the intelligent logistics link of Jabil Electronics, the efficiency of automatic handling has increased by 50%, the efficiency of three-dimensional storage has increased by 30%, and the efficiency of the entire plant has been increased by more than 10%.
