AI Technical Summary

Technical Problem

Existing protective film laminating equipment is prone to problems such as stretching deformation, damage, wrinkles, and lamination position deviation when processing different materials, which affects the lamination accuracy and effect.

Method used

The system combines a negative pressure mechanism with infrared monitoring equipment. A negative pressure fan extracts air from the bottom of the protective film to reduce air bubbles, while an electric push rod and a swing cylinder eliminate wrinkles to ensure precise bonding. At the same time, the infrared monitoring equipment monitors and adjusts wrinkles in real time, and bonding rollers and a conveyor belt ensure smooth transport.

Benefits of technology

It effectively eliminates wrinkles and bubbles, improves the accuracy and quality of protective film application, reduces material damage, and enhances equipment maintenance efficiency.
