Description

TECHNICAL FIELD

[0001] The utility model relates to the field of insulating cover film processing and handling, and particularly relates to an insulating cover film laminating device with dust removal function. BACKGROUND

[0002] An insulating cover film is a kind of film material with electrical insulation properties, mainly used for isolating current, preventing short circuit or protecting specific surfaces.

[0003] The cover film is prone to static electricity during unwinding, adsorbing tiny dust (especially particles with a particle size of less than or equal to 5 microns) in the environment, resulting in foreign matter in the laminated interface and causing defects such as air bubbles and delamination. The existing equipment lacks effective dust removal means and often relies on environmental purification or manual wiping, which has low dust removal efficiency and is difficult to eliminate static interference. For example, in high-cleanliness scenarios such as 5G high-frequency substrates and optical display modules, interface contamination directly reduces the insulation performance and yield of products, resulting in increased yield loss. In addition, there are local thickness differences on the surface of flexible substrates (such as FPC circuit boards), such as solder joints and adhesive layers. The traditional fixed pressure roller cannot dynamically adjust the pressure, which may easily cause deformation of the substrate due to excessive pressure or poor adhesion due to insufficient pressure. If the adhesion strength is uneven, it may lead to a decrease in product reliability, especially for the adhesion of curved film materials, which has low qualification rate.
