Automatic membrane tearing device of OLED membrane and membrane tearing process thereof

Abstract

The invention discloses an automatic membrane tearing device of an OLED membrane and a membrane tearing process thereof. The automatic membrane tearing device comprises a first adhesive tape pull-outassembly, an OLED membrane tearing assembly and a waste membrane collecting assembly. The first adhesive tape pull-out assembly is arranged in mounting space at the front end of a rack and is used forpulling a coiled first membrane-tearing adhesive tape out. The OLED membrane tearing assembly is arranged above the first adhesive tape pull-out assembly in a linearly sliding manner and extends horizontally above an OLED adsorption and transfer platform. The first membrane-tearing adhesive tape passes through the OLED membrane tearing assembly and has the adhesive surface facing down, so that the first membrane-tearing adhesive tape is adhered to and fixed with the surface membrane body of the OLED membrane. The OLED membrane tearing assembly drives the first membrane-tearing adhesive tape to make linear movement, so that the first membrane-tearing adhesive tape is torn from the surface of the OLED membrane; and the angle of tearing of the first membrane-tearing adhesive tape from the membrane body is controlled by a first membrane-tearing plate. Therefore, problems of surface membrane tearing of the flexible membrane, adsorption stability of membrane tearing, membrane body angle change control in membrane tearing, and automatic separation of the membrane body after membrane tearing are solved.

Description

technical field [0001] The invention relates to the field of automatic manufacturing, in particular to an OLED film automatic film tearing device and a film tearing 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.

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, 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 film and FILM film cannot be physically removed during the film tearing process. Clipping and fixing can only be fixed by vacuum adsorption or adhesion, and when the film body to be torn is torn off from the OLED diaphragm and FILM diaphragm, the adhesion between the film body and the OLED diaphragm or FILM diaphragm will decrease. Pulling the diaphragm in the opposite direction will cause the diaphragm to fail to fix and interrupt the tearing film; therefore, in view of the tearing film 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, so as to improve the tearing effect of the film. Quality; 2. OLEDs made of flexible materials need to be fixed by vacuum support when tearing off the film or laminating; The body is torn off to the other side. When the film is torn off, the film body pulls 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 to break and cause vacuum leakage. , resulting in the offset of the position of the OLED diaphragm; 3. When tearing off the film body on the surface of the OLED diaphragm with a tear-off tape, it is necessary to adhere and fix the film body to be torn off by the tear-off tape, and remove the film body from the LOED diaphragm Tear off, the torn film body adheres to the tear film tape, in order to facilitate the tear film tape to tear off the film again or to rewind and recycle, the film body attached to it needs to be removed
