The application of industrial robots in the lithium battery industry is imminent

Lithium batteries are widely used in energy storage power systems, electric vehicles, military,special and other fields. Especially with the popularity of the electric vehicle market in recent years, the demand for lithium batteries continues to rise. And can the current situation in the lithium battery industry support these applications? At present, the degree of automation in the lithium battery industry is not high, production efficiency is low, and product stability is insufficient. Industrial robots are the weapon to solve this series of "pain points", and the application of industrial robots in the lithium battery industry is imminent.

Lithium battery process and industrial robot application

The lithium battery process includes coating, slitting, baking, winding, assembly, welding, liquid injection, chemical formation, volumetric, PACK assembly, etc. The lithium battery production line can actually use robots in each link, including single processes and processes the connection between the two. However, at present, the robots are used more in the four stages of assembly, welding, chemical conversion, and packaging of the outer packaging, and the application of other links has yet to be improved.

Introduction to industrial robots currently used in the lithium battery industry

At present, the most used robots in the lithium battery industry are linear module robots and scara robots, which are mainly used for handling and changing work in the production line. Among them, SCARA robot has advantages in realizing rapid transformation of products and replacing linear slides. In the production process of digital batteries, because of the variety of products, it is necessary to change frequently, and the amount of four-axis robots is relatively large.

The power battery products are relatively simple, but six-axis robots can be used for handling and packing at the rear end of the production line; at the front and rear ends of some equipment, six-axis or four-axis robots can be equipped for loading and unloading of products, and the load is relatively large. .

In the PACK module assembly line, the heavy-load six-axis robot performs module assembly work in the production line, and the arm length is relatively long. In some equipment enterprises, the AGV robot is also used for carrying work.

Industrial robot selection for lithium battery production line

When selecting a robot, it is necessary to consider the following factors: 1) weight bearing capacity; 2) working space; 3) degree of freedom, flexibility; 4) accuracy; 5) moving speed and field of use.

New energy vehicles will continue to maintain rapid growth in the next few years. In 2017, the demand for robots in the lithium battery industry exceeded 4,500 units. In the future, the application of industrial robots in the lithium battery industry will be further expanded to help the new growth of the lithium battery industry.
