Description

Technical Field

[0001] The present invention relates to the field of automated manufacturing, and in particular to a fully automatic flexible screen laminating machine. Background Art

[0002] Flat-panel display devices are the human-computer interaction medium that displays text and images. They primarily consist of a display module, backlight module, and touchscreen module. The display module, in turn, comprises components such as the display panel, polarizers, driver IC, PCB, and FPC. Flat-panel display production is divided into the front-end array, boxing, and back-end module assembly processes. The front-end process produces the display panel, while the back-end process assembles the display panel, polarizers, backlight module, touchscreen module, and other components into a flat-panel display device. Front-end production equipment is currently primarily supplied by Japanese, Korean, and American companies and is largely unavailable domestically. However, a few domestic companies have achieved breakthroughs in back-end production equipment and are gradually replacing imported equipment. The display panel, the primary component for display functions, requires polarizers to be attached to both sides of the panel to form a display device. LCD panels require a polarizer on each of the top and bottom sides, while OLED panels require a polarizer on the top to achieve directional light transmission.

[0003] The OCA bonding process for flexible OLEDs presents the following technical difficulties in actual production: 1. The automated polarizer lamination process involves loading the flexible OLED, removing the OLED film, loading the polarizer, detecting multiple polarizers, initial positioning, removing the polarizer, and automated lamination. 2. The tearing method involved in the automated OLED and polarizer film tearing process. 3. The rapid, removable installation and fastening of the roll-bonded film. 4. During the roll-bonded film tearing process, the film can be stretched while the film is being pulled, causing the flexible OLED to shift position. Summary of the Invention

The lower side of the inclined limit plate is connected to the auxiliary support block and extends obliquely upward. A transition arc surface is provided between the inclined limit plate and the auxiliary support block. The auxiliary cylinder drives the auxiliary slide to drive the auxiliary support block and the inclined limit plate to move linearly, which can clamp the easy-tear sticker between the adhesive roller and the transition arc surface, thereby realizing the action of tearing off the film body using the easy-tear sticker. When tearing the film, while the adhesive roller or the easy-tear sticker adheres to the film body on the surface of the flexible OLED, the inclined limit plate presses down on the film body. While the adhesive roller moves linearly along the film body to tear it off, the inclined limit plate remains in a downward pressure state, thereby reducing the situation where the flexible OLED is pulled out of position and causes position displacement due to film tearing, and effectively improving the film tearing quality.
