一种无线充覆盖膜防破损的压合设备
By using the expansion of air bladders in the pressing equipment to create a pressure gradient and directional exhaust mode, combined with the reinforcement mesh to limit the trajectory of the air bladders, the problems of uneven pressure and poor exhaust in the pressing equipment are solved, thus achieving the protection against damage and tight adhesion of the cover film.

AI Technical Summary
Existing membrane lamination equipment suffers from uneven pressure distribution, leading to damage and poor venting, resulting in air bubbles.
The airbag expansion using a drum-shaped pressing roller creates a pressure gradient. Combined with a directional exhaust mode, and reinforced with mesh on the drum side and in the drum to limit the airbag expansion trajectory, this ensures uniform pressure distribution and orderly gas discharge.
It effectively prevents damage to the cover film, reduces residual air bubbles, improves production continuity and economy, and ensures a tight bond between the cover film and the substrate.
