Lithium production process is more complex, each production link involves a lot of special equipment, industrial robots, mobile robots, machine vision and other automation equipment to further enhance the automation of lithium production, intelligent degree, to ensure the production of lithium batteries with safety, reliability and better consistency and straight-through yield.

Today we will talk about the important role that AGV/AMR is gradually playing in the production of lithium batteries.

First of all, we need to understand the specific process logistics involved in lithium battery production, lithium battery production process mainly includes the first stage of the process, the middle process and the last stage of the process.

1, the previous process

The previous process mainly refers to the production of stage pieces, which mainly includes four links: mixing, coating, rolling and scuttling. In the production of lithium batteries, the previous process is very important, accounting for more than 40% of the entire battery production process. The unpacking, handling, rewinding and line side transfer of incoming materials can be replaced by AGV/AMR.

First of all, in the lithium raw material warehouse, lithium raw materials are mainly stored in the form of tons of bags. Even if the application of semi-automatic equipment, the labor intensity of people is still very large, and some scenarios have a certain risk of mechanical damage. At this time, the application of AGV/AMR can effectively solve the above problems, reduce the labor intensity of personnel, and improve the handling efficiency.

Secondly, the automatic loading and unloading of the coating, rolling and scuttering machine in the previous process can use AMR with high docking accuracy to complete the unmanned accurate docking, but the model needs to be customized according to the specific scenario of the customer; At the same time, the handling frequency of raw materials and polar coils is high, which has high requirements for AMR scheduling, rhythm and accuracy. AMR needs to deal with a large rate of environmental change, complex human-machine mixing, high cleanliness environment, these different levels of challenges. This also puts a high requirement on the technology and product reliability of AMR manufacturers.

2, the middle process

The middle process mainly includes the winding/lamination of the cell and the cell injection. In the core making process, the traditional mode is manually loading and unloading and docking with the winding laminator, which not only cannot guarantee efficiency, but also has safety risks, and more importantly, it is insufficient flexibility.

The use of AGV/AMR automatic handling and docking can solve the above problems, which can not only meet the requirements of accurate docking, adapt to a high and clean environment, but also cross regions and cross floors. With AMR’s high precision, high environmental awareness, high flexibility and high efficiency, it helps unmanned loading and unloading, handling automation, packaging automation and intelligent warehousing and logistics.

3. Back-end process

The back-end process mainly includes packaging, chemical composition, testing and sorting, module assembly, PACK assembly and finished product storage. At this stage, there are more processes involved, and AGV/AMR can play a role in the transfer and connection between different processes, so that each process can be more orderly and efficient flow. This is especially reflected in the Pack line at the back end and the finished product storage link, where standard load AMR and heavy load AMR and forklift AMR play an important role in this link, greatly reducing the artificial pressure.

In the past two years, the iteration of lithium battery technology has been accelerating, the process is complex, and CTP technology 3.0, blade battery, short knife battery, 4680 cylinder battery, and different module design structure have prompted the development of the lithium battery industry automation production line to differentiation and flexibility.

Due to the different types of demand, orders often appear in the form of multiple batches and small batches, at this time, the highly flexible mobile robot AMR+ software system platform can precisely adapt to this change, in response to the changing market demand, more flexible production line layout, more efficient and rapid rhythm, lithium battery manufacturing will be automated, intelligent and flexible direction.
