High-Precision Alignment and Lamination of Automotive Windshields and PVD Films

The method of bidirectional alignment lamination of PVD film and glass includes the following steps: the alignment platform module drives the film on the alignment platform tray to move left or right and forward or backward to a certain position, exposing the adjacent sides of the film and the adjacent sides of the glass relative to the film; camera takes a photo; the bidirectional alignment lamination mechanism records the position of the adjacent sides of the film and the position of the adjacent sides of the glass relative to the film through the camera; the position deviation between the film and the glass is calculated based on the film edge and glass edge recorded by the camera; finally, the alignment platform module aligns the center of the film with the center of the glass.

Simple adjustment:
Just need to make sure the film and glass appear in the camera,
The alignment accuracy is not significantly affected after the camera moves
Fixed glass:
During and after alignment, the glass does not move,
Reducing errors caused by movement
Simple coordinate integration:
Coordinate integration is simple,
There is no error in coordinate integration
Separate photography:
The camera takes photos of the film
and glass separately without interference
