Description

Technical Field

[0001] The utility model relates to the technical field of soft-pack battery core processing, in particular to a core rubber material film tearing component for soft-pack batteries. Background Art

[0002] In the production process of battery modules for soft-pack batteries, battery cells are combined in a stacked manner to form a complete battery module. In order to ensure the structural stability and thermal management performance between the battery cells, each battery cell needs to be glued before stacking. The gluing process usually includes loading, gluing, and film tearing. Among them, the film tearing process is the key link in the gluing process, which affects the bonding quality of the glue and the reliability of the battery cell stacking. In the existing technology, the film tearing after the battery cell is glued is usually completed manually or semi-automatically. Among them, manual film tearing has the problems of low efficiency and poor consistency, and the adhesive layer is easily damaged or residual film pieces are left due to uneven force during the operation, affecting the bonding strength of the battery cell parts. Although semi-automatic film tearing can improve some efficiency, some processes still require manual intervention, which restricts production efficiency and process consistency, and it is difficult to meet the needs of large-scale mass production.
