Zherong County, Fujian Province, is known as the "hometown of Chinese knives and scissors". Local craftsmen forge knives and scissors with pig iron and steel blades, and create three core processes: water grinding, quenching, and steel cutting. The sharpened scissors have sharp edges and are durable. Nowadays, Zherong Knife and Scissors has formed a product matrix of 25 varieties and hundreds of specifications, with an annual output of over 300 million knives and scissors. In the face of the global trend of intelligent transformation in the manufacturing industry, Fujian Mobile has deeply cooperated with Zherong Knife and Scissors Enterprise, using 5G, AI, and big data as core technologies to create a 5G digital workshop for the knife and scissors industry. Through an integrated architecture of "end management cloud use", the digitization of the entire production factor chain is achieved. In traditional scissor processing, manual processes account for over 50%, with high labor intensity, high dependence on worker skills and experience for process quality, and safety risks. Fujian Mobile has customized a digital technology transformation plan for Jinjian Scissors Co., Ltd. in Zherong County. A 5G private network has been set up in the factory to collect real-time status, parameters, and production capacity data of CNC grinding machines and other equipment. With the support of a comprehensive data management platform, a monitoring model has been configured to achieve full process data management, realizing digital visualization and proactive predictive maintenance of the workshop. At the same time, the use of digital spark machines, automatic welding machines and other equipment to promote automated processing reduces manual errors and labor intensity, and minimizes safety risks. At Zherong Zhengrong Hardware Company, a fully automatic production line for casting tool handles is working tirelessly - a 6-axis robot with independent movement and precise control of objects, a sand spraying machine with automatic adjustment of sand spraying volume and mode, a dewaxing kettle with internal heater and control system, an automatic wax injection machine, an automatic paste making machine are all producing wax paste. In addition, there are robot automatic shell making production lines, electric furnaces equipped with PLC programmable controllers, and other equipment that are all producing wax paste automatically. These digital production equipment are fully connected to the entire scissor production process through the 5G network in the factory area. It is worth mentioning that the manufacturing techniques of Zherong knives and scissors, as a provincial-level intangible cultural heritage, have long relied on the transmission of the core craftsmanship by craftsmen. In the future, with the help of digital technology, the exquisite skills of craftsmen will be transformed into storable and analyzable data assets. Young craftsmen can use digital twin technology to repeatedly simulate and practice traditional crafts in a virtual environment, shortening the learning cycle. The process parameters recorded in the cockpit of the data window also provide scientific basis for process improvement, allowing ancient intangible cultural heritage techniques to shine with new vitality and vigor in the new era. From the resounding sound on the anvil to the data flow in the cloud, 5G is no longer just cold code, but the key to bringing intangible cultural heritage skills to life and making old brands trendy.
