Digitalization empowers "lighthouse factories" to illuminate home appliance manufacturing
2023-10-26
Among the global "lighthouse factories", China continues to rank first with a number of 50, of which 12 are home appliance enterprises, and the home appliance industry has become the industry with the highest number of selected companies; In 2022, the main business revenue of China's home appliance industry reached a new high, reaching 1.75 trillion yuan, making it still the world's largest producer and seller of home appliances; In the same year, the total R&D investment of 50 listed companies in home appliances exceeded 41.8 billion yuan, and the level of intelligent technology application was among the top in the world... As a traditional advantageous industry, in recent years, home appliance enterprises have increased their investment in automation and digitization, actively promoting the deep integration of new generation information technology and intelligent technology with traditional home appliance manufacturing, and embarked on the upgrade path from "manufacturing" to "intelligent manufacturing". Tick and Tick... In just 20 seconds, the reporter saw that a steel plate has completed more than ten processes such as cutting, punching, welding, bulging, flanging, pressing, and testing, transforming into an inner cylinder of a washing machine. Within a day, automated production lines constantly "eat" rolls of steel plates and various raw materials, "spit out" washing machines one by one to enter the end market and user households. This is not a magic trick, but a real production scene of the transformation of the home appliance industry's "smart manufacturing". In Haier's "lighthouse factory" located in Tianjin, this scene keeps happening. The inner cylinder is the core component of washing machines, and the factory's inner cylinder module production line is the world's first 5G interconnected inner cylinder module line. The stainless steel coil is automatically transmitted into the punching machine, and after 6 stamping operations, more than 3000 drainage holes with a size of only 2mm are punched. Subsequently, advanced laser welding technology "welded" the two ends of the steel plate together, transforming it into a barrel. It is said to be "welded dead" because the strength of the weld seam even exceeds the strength of the base material. Under this welding strength, the inner cylinder speed is increased from 800 rpm to 1600 rpm, providing users with the best dehydration and drying experience, while reducing the potential damage to clothing caused by large aperture. "Chen Yong, the information technology manager of Haier Tianjin Washing Machine Interconnection Factory, told reporters. At the same time, the "facade" of the washing machine - the outer shell - experienced a miraculous transformation journey. It was also operated by a mechanical arm from the steel plate coil entering the production line and sent to various production nodes, completing various processes from stamping, bending, riveting to powder spraying. The production time of the outer shell was also 2 seconds faster. Although the production rhythm of each component is different, they can perfectly 'meet' on the production line, thanks to the digital three-dimensional logistics distribution system. Chen Yong said that the cleverness of this logistics system lies in its ability to decompose weekly orders pre planned based on the final assembly, create daily order plans in advance, and sort them. The system automatically sends the required materials to the production line in advance according to the sorted orders. A certain amount of buffer area is set in the logistics system for each process, and the system will schedule in advance to ensure the continuity of production, so that the washing machine can walk off the production line with quality and quantity guaranteed and enter thousands of households. Haier Tianjin "Lighthouse Factory" is one of the representatives of the home appliance industry's increasingly "smart" manufacturing processes and achieving quality and efficiency improvement. Jiang Feng, Executive Chairman of the China Home Appliances Association, recently wrote that in the past five years, home appliance companies have increased their investment in automation and digitization, actively promoting the new generation of information technology and intelligence
