Description

Technical Field

[0001] The utility model relates to the field technology of soft-pack lithium battery processing, in particular to a top-side sealing and liquid injection integrated machine. Background Art

[0002] With the shortage of energy and the pressure of environmental protection in the world, large-capacity power batteries have gradually become the main body of power supply. Among them, lithium batteries, as green batteries, have gradually become the first choice for power supply market applications because they do not cause secondary pollution and have no memory effect.

[0003] The top and side sealing process is of great importance in the production process of soft-pack lithium batteries. It is not only the first step in battery assembly, but also the expansion process has a great impact on the subsequent battery performance. The packaging process is to manually place the battery core → fold the aluminum-plastic film in half → side sealing → top sealing → corner sealing; From the above processes, it can be seen that the existing power soft-pack lithium battery packaging production process has the following defects: 1. The aluminum-plastic film needs to be transported and loaded and unloaded for many times, and the production equipment is shut down and the waiting time is long; 2. Workers need to carry out multiple handling and loading and unloading operations on the battery packaging, which is labor-intensive; 3. After multiple handling and loading and unloading operations, the quality is unstable, the production efficiency is low, and the labor cost is high; 4. The production equipment is scattered, covers a large area, and requires a large factory area;

[0004] The second is the liquid injection process, which involves manual feeding → manual handling → liquid injection. After the liquid injection is completed, the material is discharged by manual handling. Some processes are completed by manual shell and machine cooperation. The production efficiency is slow and large-scale production cannot be carried out. Later, multiple different independent equipment were used on the market to achieve this. Although fully automated assembly can be achieved, intermediate products need to be transferred between different equipment, which consumes a lot of manpower and material resources. The operation and control are troublesome. At the same time, multiple equipment take up a large space in the workshop and are troublesome to manage.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
