AI Technical Summary

⚠Technical Problem

Existing technologies suffer from poor strip adhesion during the assembly of layered stacked parts, leading to cracks, vibration, and noise. Furthermore, frequent maintenance of sprayers and nozzles results in production downtime and increased costs.

⚗Method used

A combination of a die-cutting station and a gluing station is used. The glue is applied discretely to the surface of the strip by a synchronously moving gluing unit, avoiding the use of nozzles and pumps. The strip is glued by two-component or one-component glue.

🎯Benefits of technology

It improves the electrical performance of layered stacked components, reduces machine downtime and maintenance costs, and ensures a fast, clean, and efficient assembly process.
