Application of industrial robots in the lithium battery industry

For the industrial lithium battery industry that has continued to heat up in recent years, 'machine substitution' seems more urgent. Behind the current prosperity of the lithium battery equipment industry, there are still 'pain points' such as low efficiency, poor stability, and low automation. And this contradiction is exactly the opportunity that triggered the explosion of robot applications. The demand for the development of industrial robots in the lithium battery industry Lithium batteries are widely used in energy storage power systems, electric vehicles, military, aviation and other fields. Especially with the booming electric vehicle market in recent years, the demand for lithium batteries has continued to rise. And can the current situation of the lithium battery industry support these applications? According to relevant investigations, the current level of automation in the lithium battery industry is not high, production efficiency is low, and product stability is insufficient. Industrial robots are a sharp weapon to solve this series of 'pain pointsFrom the input of raw materials to the output of PACK, the equipment involved is roughly summarized as follows. It should be noted that not every lithium battery manufacturer has adopted the equipment listed below, but has some choices based on the company’s own situation. For example, most of the batteries are still semi-automatic equipment or manual processing in the later stages of cell production and the PACK stage. The degree of automation is low, especially in the stages of packaging, testing, and warehousing. The editor of Cuneng Electric believes that the application opportunities of industrial robots from the front stage of lithium battery cell production to the lamination/winding stage are slim. From the lamination blanking stage to the battery cell packaging stage, the opportunities for industrial robots mainly lie in the connection between the equipment. Use Cartesian coordinates or SCARA for connection, and during the packaging and storage stage, SCARA and light-load multi-joint industrial robots may be appropriately considered. The selection of industrial robots for the lithium battery production line. When selecting the robots, the following factors need to be considered: 1) holding capacity; 2) working space; 3) degree of freedom and flexibility; 4) accuracy; 5) moving speed and field of use . The application of industrial robots in the lithium battery industry will be further expanded. By combining robot technology with lithium battery production technology, the automation and intelligence of the lithium battery production line can be greatly improved, the production efficiency and product quality will be improved, and the lithium battery production enterprises will be driven to develop technology. Upgrade and transformation. At the same time, integration with intelligent manufacturing technologies such as artificial intelligence technology, automation, and information technology is not only a prerequisite for the realization of unmanned chemical factories, but also the future development trend of domestic discrete manufacturing production lines such as lithium batteries. The lithium battery manufacturing process includes coating, slitting, baking, winding, assembly, welding, liquid injection, chemical conversion, sub-capacity, PACK assembly, etc. Each link of the lithium battery production line can actually use robots, including single processes and processes. Between the convergence. However, robots are currently used more in the four links of assembly, welding, chemical conversion, and outer packaging Pack assembly lines, while the application of other links needs to be explored and improved. For this reason, some relevant companies are currently doing a comprehensive upgrade of production line automation and digitalization. Let the robot penetrate into all aspects of the lithium battery manufacturing process. At present, the most commonly used robots in the lithium battery industry are linear modular robots and SCARA robots, which are mainly used for handling and changing in the production line. Among them, SCARA robots have advantages in achieving rapid product transformation and replacing linear sliding tables. In the production process of digital batteries, because of the variety of products, frequent changes are required, and the use of four-axis robots is relatively large. The power lithium battery product is relatively single, but six-axis robots can be used for handling and packing at the back end of the production line; at the front and back ends of some equipment, six-axis or four-axis robots can be equipped for loading and unloading of products. Load comparison Big. In the PACK module assembly line, heavy-duty six-axis robots perform module assembly work in the production line, and the arm length is relatively long; and in some equipment companies, AGV robots are also used for handling. Nowadays, lithium batteries are developing in the direction of safety and standardization. The high-precision, high-efficiency, serialization and high-automation production lines of equipment will become the general direction of the development of the industry; at the same time, it is necessary to reduce labor costs and improve equipment automation and unmanned Prerequisite, digital intelligence is also the core competitiveness of enterprises to minimize security risks and losses. According to relevant data, in 2018, the demand for robots in the lithium battery industry exceeded 4,500. In the next few years, new energy vehicles will continue to maintain rapid growth, and the demand for lithium batteries is still strong. It is expected that the application of robots on lithium battery production lines will further expand in the future. , Helping the new growth of the lithium battery industry. Summary: The application of industrial robots in the power lithium battery industry has been relatively mature. Customers' production capacity has been significantly expanded and they are very satisfied with the product quality. I believe that the power lithium battery industry will live up to expectations and bring greater benefits to everyone.
