OLED flexible laminating device and laminating process thereof

Abstract

The invention discloses an OLED flexible laminating device and a laminating process thereof. The device comprises a laminating bracket, a laminating linear module, a laminating linear sliding seat, alaminating lifting motor, a laminating mounting seat, a laminating weight elimination cylinder, a laminating lifting seat and a laminating head, wherein the laminating bracket is arranged at the rearend of a frame; the laminating linear module is arranged on the upper part of the laminating bracket; the laminating linear sliding seat is arranged on the laminating linear module along the directionperpendicular to the laminating linear module; the laminating lifting motor is arranged on the upper part of the laminating linear sliding seat; the laminating mounting seat is arranged on the otherside of the laminating linear sliding seat, the laminating weight elimination cylinder is arranged in the laminating mounting seat, and the output end is connected with the laminating head; and the laminating lifting seat is slidably arranged on the side wall at one side of the laminating linear sliding seat. According to the scheme of the invention, the height difference forms at the two ends ofan adhesive film strip, so that the FILM membrane and an OLED membrane are in linear contact, laminating bubbles are effectively reduced, and the angle change during lamination of the FILM membrane iscontrolled through the up-down adjustable film pressing roller, so that the separation of the FILM membrane can be prevented.

Description

technical field [0001] The invention relates to the field of automatic manufacturing, in particular to an OLED flexible bonding device and a bonding process thereof. Background technique [0002] An OLED display is a display made of organic electroluminescent diodes. Since it also has self-luminous organic electroluminescent diodes, no backlight is required, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, wide operating temperature range, simple structure and manufacturing process, etc. , is considered to be the next-generation flat-panel display emerging application technology. OLED is a self-luminous material that does not need a backlight panel. At the same time, it has a wide viewing angle, uniform image quality, fast response speed, easy colorization, light emission can be achieved with a simple driving circuit, simple manufacturing process, and can be made into a flexible panel. In line with the principle of li...

Problems solved by technology

During the manufacturing process of the OLED display, it is necessary to attach a FILM film which is also flexible on its surface; and when the OLED film and the FILM film are supplied, the surface is attached with a protective film body, and the FILM film and the OLED film need to be separated before attaching the FILM film and the OLED film. After tearing off the surface of the OLED diaphragm and the film body on the bottom surface of the FILM diaphragm, the two are then bonded together; in the process of automatically pasting the FILM film on the OLED diaphragm, the following key technical problems need to be solved: 1. FILM diaphragm One side of the FPC is mostly connected to the FPC. During the transfer and bonding process of the FILM diaphragm, affected by the gravity of the FPC itself, the FPC hangs down and bends to the FILM tearing film platform or the OLED diaphragm, causing the FILM diaphragm to be damaged and easily affected. FILM placement or bonding; therefore, it is necessary to design an auxiliary holding structure for the FPC of the FILM diaphragm to ensure that it does not hang and bend during its handling and bonding; 2. The two bonding planes of the FILM diaphragm and the OLED diaphragm are mutually When bonding together, the entire surface is directly bonded through the traditional rigid bonding seat. After the bonding is completed, air bubbles are likely to appear between the two bonding planes, and the bonding quality cannot be effectively guaranteed; in view of the flexible and bendable characteristics of the FILM film, it is necessary to Design a way to form a height difference between the two ends of the FILM when laminating, and roll from one side of the FILM film to the other through the slidable rolling structure in the middle, so as to replace the planar contact lamination by line contact lamination, to achieve The purpose of reducing lamination air bubbles; 3. Use the adhesive film tape to adhere and fix the FILM diaphragm upwards, and when the FILM diaphragm is attached to the OLED diaphragm downwards, the FILM diaphragm is pressed downward by the laminating roller, and the film is removed from the adhesive film Peel off the tape and attach it to the OLED film; when the peeling angle of the FILM film from the mucous tape changes too much, it is easy to be directly detached from the mucous film, resulting in the position shift of the FILM film and the failure of bonding
