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. 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...

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 d
