New energy battery manufacturers through the introduction of digital, intelligent technology into the production line of key processes and supply chain operations of key nodes, to improve the battery production and logistics operations of automation and intelligence, not only to improve working conditions, reduce the labor intensity of operators, but also improve production efficiency and product quality.best lithium ion battery machine company This is undoubtedly the future direction of new energy battery production, but also faces many technical challenges.

Intelligent logistics technology to help new energy development

In recent years, China's new energy automobile industry has been rapid development, in which the new energy battery production and manufacturing is one of the key core technologies. The initial production and assembly of new energy batteries, many links need to be completed manually, labor intensity and low efficiency.equipment for lithium battery assembly In addition, as the production of new energy batteries involves hazardous materials, the health of workers will be threatened. For example, in the production of battery pole rolls, the powder needs to be stirred, then coated, cold pressed, pre-slitting, die-cutting, slitting, winding, and finally assembled into a battery cell. If these production processes are completed manually, it is difficult to avoid the impact of powder on human health. For this reason, the manufacturer has specially designed an automatic loading device, so that the problems of manual operation can be avoided.

In addition, in the whole system of new energy battery production and assembly, there are many links that require the application of the latest logistics technology, such as workstation transportation. Workstation transportation is an important part of the entire production line, and its design structure directly affects the feasibility of battery packaging, product quality and production rhythm. According to the precision and flexibility requirements of workstation transportation, some use roller conveyor line transportation, some use AGV transportation. Some production lines adopt multi-station transportation, which is mainly realized by means of stacking roller conveyor: on the roller conveyor of modular production line, there are read/write heads, detection switches, checking devices, material blocking devices and so on. When transporting materials, the movement of the roller conveyor can be adjusted according to the requirements of each station during assembly to meet the requirements of each station during battery assembly.

It is worth mentioning that more and more robotic devices are beginning to appear in the production and logistics of new energy batteries. With the decline in the price of robots, robots in the production and logistics operations to replace the advantages of manual labor gradually appeared. The application of robots has the advantages of high precision, high reliability and production flexibility, which can greatly improve production efficiency and product quality. At the same time, the integration of robotics with artificial intelligence, automation, information technology and other new technologies is not only a prerequisite for the realization of unmanned chemical plants, but also a development trend for the intelligent upgrading of discrete manufacturing production lines such as new energy batteries in China.

Information and digital technology everywhere

The quality of new energy battery pack manufacturing and assembly directly affects the performance and even safety of new energy vehicles, so the quality requirements for new energy batteries are very strict, which makes the production, assembly and logistics of new energy batteries more and more dependent on informationization and digital technology. In addition, today's new energy battery single workshop pursues greater capacity, which requires more informationized production management system as support.

If we want to drive the whole process structure of new energy battery supply chain through digital technology, we need to establish a perfect digital information management system first, in which the top system is the company's ERP system, which is responsible for the management of documents such as purchase orders, sales orders, etc., and transmits the information of the documents downward to guide the execution of specific business, and at the same time, receives the result of the implementation of the WMS system for enterprise resource management; the middle system is the WMS system, which is positioned as the execution layer, and is responsible for the implementation of the WMS system. System, positioned as the implementation layer, is responsible for the overall process of warehousing logistics control, upward acceptance of the ERP system documents as the basis for implementation, downward transmission of specific implementation instructions, and acceptance of the results of the implementation of the library system, the final results of the data back to the ERP system, play a role in carrying on the role of the bottom; grass-roots system is mainly a warehousing center library system, positioned as the control layer, responsible for the library of the internal management as well as the integration of hardware and equipment The base system is mainly the warehouse center system, which is positioned as the control layer, responsible for the internal management of the warehouse and the integration of hardware and equipment, receiving the instructions from the WMS and carrying out specific picking actions, and at the same time, feeding back the execution results to the WMS.

In the entire system of new energy battery production, the digital supply chain needs to connect the material warehouse, production plant, semi-finished product warehouse and finished product warehouse. For example, in the case of digitally-driven plant logistics, the specific operations involved include the operation of automatic three-dimensional warehouses for raw materials, automatic three-dimensional warehouses for structural components, automatic three-dimensional warehouses for copper foils and automatic three-dimensional warehouses for semi-finished products, as well as the operation of raw materials to the workshop via AGVs, air routes, forklift trucks, and other means of transportation, and so on.

For the demand of quality control, a large amount of information needs to be confirmed immediately in the production process of new energy battery, mainly including: assembly performance, i.e., the traceability information of raw materials summarized in the production process of the product; process parameters, i.e., the parameter data related to the performance of the product in the production process; quality inspection information, i.e., the relevant records and codes of the quality inspection in the production process; step performance, i.e., the processing information of each process in the production process of the product Processing information; equipment parameters, that is, the product production process of equipment set parameters data; rework information, that is, the product defects rework after repair records. These all need digital technology to realize.
