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 film body on the surface of the OLED film and the bottom surface of the FILM film, the two are then bonded together; in the process of automatically attaching the FILM film to the OLED film, the following key technical problems need to be solved: 1. FILM and OLED When laminating, it needs to be laminated up and down. In the process of process design, it is necessary to tear off the film body directly from the bottom and top of the FILM and OLED; due to the limitation of the flexible characteristics of OLED and FILM, the OLED diaphragm and FILM diaphragm are in the process of tearing the film. During the process, it cannot be physically clamped and fixed, but can only be fixed by vacuum adsorption or adhesion. When the film to be torn is torn off from the OLED diaphragm and FILM diaphragm, the gap between the film body and the OLED diaphragm or FILM diaphragm The adhesive force will pull the diaphragm in the opposite direction, causing the diaphragm to fail to fix and interrupt the tearing film; therefore, in view of the tearing requirements of this kind of flexible diaphragm, it is necessary to effectively control the tension between the film body and the diaphragm during the tearing process, In order to improve the quality of the tear film; 2. One side of the FILM film is often connected with FPC. During the transfer and bonding process of the FILM film, affected by the gravity of the FPC itself, the FPC hangs down and bends to the FILM film tearing platform or OLED film On the film, it will cause damage to the FILM diaphragm and easily affect the placement or bonding of the FILM; 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 handling and bonding; 3. Flexible material The OLED needs to be fixed by vacuum support when tearing the film or laminating; when tearing the OLED film, it is necessary to tear the film body upward from one side, and gradually tear the film body from one side to the other. When tearing the film, the membrane body will pull the OLED diaphragm upwards, so that the OLED diaphragm on the side of the tearing film tends to lift upwards, which will cause the vacuum of the vacuum support platform to break, and a vacuum leak will occur, resulting in the position of the OLED diaphragm. 4. When the two bonding planes of the FILM film and the OLED film are bonded to each other, they are directly bonded on the whole surface through the traditional rigid bonding seat. After the bonding is completed, the two bonding planes Bubbles are very easy to appear between the 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 method that uses a height difference between the two ends of the FILM during bonding, and a sliding rolling structure in the middle. One side of the FILM film is rolled to the other side to replace plane contact bonding by line contact bonding to reduce bonding air bubbles
