Benefiting from the continuous expansion demand of the lithium battery industry, the sales of robots in the lithium battery industry have shown a rapid growth trend. According to the data of the High-tech Robot Industry Research Institute (GGII), in 2021, the sales volume of industrial robots (six-axis and SCARA robots) in China's lithium battery industry will be 19,700 units, a year-on-year increase of 98.18%, of which 9,255 six-axis robots will be sold, a year-on-year increase of 102.61%.

A multi-joint robot is defined as a robot with multiple rotating joints in the arm, which is generally composed of a column and a large and small arm. The more axes (joints), the higher the degree of freedom. More than 6 axes are redundant degrees of freedom, of which 4- 6-axis is the most common.

 

Specifically, multi-joint robots have two main characteristics:

01

It has a large load range, ranging from less than 1KG to 2-3 tons, which can meet the load requirements of various tasks.

02

It has a large working range and can be suitable for almost any trajectory or angle of work.

 

At present, the processes that multi-joint robots are involved in in the production of lithium batteries are mainly concentrated in the middle and back stages, and the modules and PACK links are the most used, including handling, loading and unloading, gluing, stacking, welding, sorting, Cleaning, boxing, locking, testing, packaging and other links.

From the perspective of application scenarios

 

From the perspective of application scenarios, the field of power lithium batteries is the "highland" for the application of multi-joint robots in the lithium battery industry. , module assembly, module fastening and other specific application procedures have been implemented. In the field of digital lithium batteries, due to the variety of battery products, frequent replacement is required, and SCARA is used in a relatively large amount. In some scenarios, collaborative robots have also been introduced, and multi-joint robots are used. less.

From the point of view of entering enterprises

 

From the point of view of the enterprises entering the bureau, the multi-joint robots currently used in the lithium battery industry are mostly foreign-brand robots. Even though there are fewer domestic enterprises, in the foreseeable future, the lithium battery industry that is still expanding is already multi-joint robots. One of the "blue oceans" of competition.

From a specific trend

 

From the perspective of specific trends, in the next few years, the multi-joint robots used in the lithium battery industry may show the following characteristics:

 

01

Robots must be reconfigurable and reusable: in addition to focusing on traditional quality, cost, flexibility and efficiency, they must respond quickly to the market, resist various disturbances, and be reconfigurable and reusable. promote.

02

Self-awareness and self-adaptation: Robots need to have self-awareness, self-adaptation, self-compensation, and self-adjustment to the production environment.

03

High stability and high reliability: In the lithium battery industry, production stoppages and failures are very sensitive, so multi-joint robots must not only have high stability and reliability, but also be able to achieve predictive automatic problem tracing, as well as zero defect, Zero-failure capability.

04

Industry customization: Customize exclusive robots according to the battery production process, and develop special industrial robots for the processes that multi-joint robots have not penetrated in the lithium battery industry.

05

High cost performance: The cost pressure of the lithium battery industry chain is high, and the automated production line has a large investment at one time. The cost performance of robots is a key point for the lithium battery industry to consider.
