Welding robots are industrial robots that perform welding (including cutting and spraying). Welding robots have opened up a new direction in automation, namely flexible automation, also known as programmable automation. With the development of electronic technology, computer technology, numerical control and robotics, automatic welding robot technology has become increasingly mature since being put into production since the 1960s. The temperature in Chinalco Ruimin's aluminum coil welding environment is high, not suitable for welding workers to stay on site for a long time, so welding robots are introduced. The welding robot is equipped with intelligent automatic welding function for cold-worked workpieces of different specifications, and on the basis of the supporting welding process package, the welding process package applicable to the company's cold-worked welded workpieces is created, thereby realizing intelligent and automatic 24-hour unmanned welding operation. Without any hardware modifications, the welding robot imitates and reproduces every operation taught with high precision. The welding robot can now perform the same tasks as a skilled welder with improved accuracy and productivity, working nonstop day and night. Welding robots have the following six advantages: (1) Producing stable and reliable welding quality; (2) Robots can work for a long time in environments that are not suitable for humans, such as high temperature, noisy, toxic, vacuum, underwater, and radioactive environments; (3) Reducing the requirements for welders’ operating skills; (4) Allowing single piece or small batch automatic welding; (5) Significantly shortening the production preparation cycle for product re-modeling or replacement, reducing the cost in the investment of equipment; (6) Providing possibility for the realization of fully automated welding production - the implementation of flexible welding production lines - in the future;

Laser etching refers to a process in which a focused laser is directed at the surface of a hard object to create an etch. Fine precision and little damage to the etched object are benefits of laser etching. The temperature of aluminum coils in the hot rolling workshop can reach 300°C after rolling, making it unsafe for workers to work there for an extended period of time. In addition, because of the requirements for the aluminum coils’ manufacturing process, the ink marking is prone to coming off, leading to unclear marking that reduces the productivity of the product's subsequent processing. Chinalco Ruimin has purchased a new laser etching machine for marking information on aluminum coils. The laser marking system for aluminum coils solves the problems caused by high temperatures, requires no consumables, has low running costs, is reliable, has low maintenance costs, and reduces labor costs at the same time. The laser marking system marks clearly and beautifully and causes no peeling off. It reduces the risk of marking incorrect information by operators and improves the accuracy of aluminum coil information. It improves the automation and intelligence of production. Laser etching technology has a wide range of applications in electronics, optoelectronics, microelectronics, aerospace and aviation. The principle of the technology is to use the high energy density of the laser beam to heat the material surface locally to the evaporation temperature to cause a chemical reaction or physical change on its surface, thereby realizing the processing of the material surface. Laser etching technology has the advantages of non-contact processing, high precision, high efficiency, no pollution, etc. It can be used to process various materials, such as metals, non-metals, semiconductors and the like.

Aluminum panel painting is a kind of aluminum alloy cultural product developed by laser printing technology, digital ink printing technology and thermal transfer printing technology. Chinalco Ruimin actively develops aluminum alloy cultural derivatives through image authorization, limited reproduction, agency and other forms. Aluminum panel painting is featured by good effect, high color saturation, high surface gloss, fastness, colorfast, etc. It can maintain the original appearance of calligraphy and painting for a long time, and can also anodize aluminum plates of different colors to make calligraphy and painting, and improve the beauty of calligraphy and painting. It can be widely used in art collections, murals, interior decorations, wedding photos, photographs, decorative paintings, advertising signs, medals and the like.

Digital twin is an integrated simulation process that makes full use of data such as physical model, sensor update, and operation history, and completes mapping in virtual space to reflect the whole life cycle process of the corresponding physical equipment. Factories are simulated in the virtual space, and the real parameters are transmitted to the actual plant construction. The product can be widely used in industrial production, and has significant advantages in the optimization and adjustment of industrial manufacturing processes and the maintenance and management of industrial equipment. Besides, it can greatly enhance the efficiency of industrial production, reduce the waste of personnel, energy and resources, monitor the status and operation of the equipment in real time through the digital simulation of the equipment to detect anomalies and failures in advance and timely carry out maintenance and processing, thereby avoiding production interruptions and losses.

Manufacturing execution system (MES) is a set of production information management system for the workshop execution level of manufacturing enterprises. MES can create a solid, reliable, comprehensive and feasible manufacturing collaborative management platform for enterprises. Chinalco Ruimin has developed a Manufacturing Execution System (MES) suitable for the non-ferrous metal processing industry, which can plan and organize production and business activities in a reasonable and effective manner and make production and business activities coordinated and orderly based on various resource situations and business process information related to manufacturing execution, achieving efficient control and management throughout the entire production process. Through the system, enterprises achieve paperless production, effectively improving labor and production efficiency, improving product quality, and enhancing flexible manufacturing capacity.

Automatic Guided Vehicle (AGV) is an industrial vehicle that loads goods by automatic or manual means, travels automatically to a designated place according to a set route, and then loads and unloads the goods by automatic or manual means. Chinalco Ruimin realizes unmanned transportation of materials between multiple equipment and areas via AGVs. The laser detection technology is used to locate and detect obstacles, determine the route of AGV and ensure the safety of on-site personnel. The interconnection between multiple systems (MES system, AGV scheduling system, logistics management system, WMS system) centered on MES system is built to achieve digital and paperless operation in workshops. Through the wireless terminal PDA, the field personnel can assign tasks wirelessly. A set of complex transport lines integrating crane, AGV and man-machine interaction is built to improve production efficiency.
