AI Technical Summary
The existing processing technology for mesh-type adhesive films results in poor flatness and high defect rate, as well as problems such as difficult coating curing, peeling, sticking, and microcracks in the battery cells.
The system employs a first pressure roller group and a second pressure roller group that are continuously arranged. The first pressure roller group forms a grid-like second adhesive film area, and the second pressure roller group fills the gaps in the grid to form the first adhesive film area, thus achieving one-piece molding, avoiding the need for printing coatings, and ensuring that the thickness of the adhesive film area is consistent.
It improves the flatness and yield of the mesh film, reduces production costs, avoids microcracks and coating peeling in the cells, and ensures that the cells are neat and uniform.
