Film pressing device and film pressing method

Abstract

The invention provides a film pressing device and a film pressing method, which are used for pasting a film layer on a substrate. The lamination device includes: a stage for carrying and transporting the substrate; a coating part for covering the film layer on the surface of the substrate; rolling on the substrate covered with the film layer for paving and removing The first roll of bubble treatment; the deformable layer arranged on the first roll, the deformable layer can be deformed to change the roll-pressed dot pattern on the outer peripheral surface of the first roll, so that the roll-pressed dot of the first roll The pattern matches the surface of the substrate; an alignment structure for aligning the substrate and the first roll. In the present invention, since a deformable deformation layer is provided on the first roller, the deformation of the deformation layer causes the rolling dot pattern on the outer surface of the first roller to match the surface of the substrate, so that when passing through the first roller When the wheel rolls and paves the surface of the substrate covered with a film layer to remove bubbles, the force on each area of ​​the substrate surface is uniform, reducing the existence of film bubbles and improving the quality of the film.

Description

technical field [0001] The invention relates to a substrate manufacturing device, in particular to a lamination device and a lamination method. Background technique [0002] AMOLED (Active-matrix organic light emitting diode, active matrix organic light emitting diode or active matrix organic light emitting diode) has a wide viewing angle, high resolution, high brightness, fast response, low energy consumption, self-illumination, ultra-thin And other characteristics, known as the third generation of display technology revolution. [0003] Usually, the substrate of the AMOLED display panel is formed by pasting the AMOLED film layer on the substrate to be filmed by an AMOLED laminating machine. Existing AMOLED laminators mainly include: a stage for carrying and conveying the substrate to be laminated; an equalizing roller arranged above the stage; a glue roller for coating an adhesive layer on the substrate; and, The AMOLED film layer is coated on the coating part on the sur...

AI Technical Summary

Problems solved by technology

[0005] The surface flatness of each area of ​​the surface of the substrate to be filmed is not uniform, so that after the AMOLED film layer is pressed on the substrate coated with the adhesive layer, when it is rolled by the uniform pressure roller, it will be due to uniformity. The pressure between the pressure roller and the surface of the substrate is uneven, which leads to problems such as bubbles in the film, which affects the quality of the film
