Abstract
Description
Technical Field
[0001] This utility model belongs to the field of liquid crystal display device manufacturing technology, specifically a light guide plate adhesive bonding fixture. Background Technology
[0002] The light guide plate is a core optical component in liquid crystal display (LCD) devices. Its main function is to transform line light sources or point light sources (such as LED backlights) incident from the side into uniform surface light sources through optical design, thereby providing illumination for the LCD panel to achieve clear and bright image display. The light guide plate adhesive bonding fixture is a special tool used in LCD device manufacturing and related fields to assist in completing the work of bonding adhesive strips or adhesive layers to the light guide plate.
[0003] However, the following problems were found in the implementation of the relevant technologies:
[0004] Existing light guide plate adhesive application fixtures mostly use simple slots or fixed brackets for positioning, which cannot accurately adapt to light guide plates of different shapes and sizes. Misalignment is prone to occur during the adhesive application process. Even some fixtures with positioning components suffer from poor structural design, making it difficult to guarantee positioning stability. This leads to deviations in the adhesive strip's placement, affecting the optical performance of the light guide plate and subsequent display effects. Furthermore, most existing adhesive application fixtures do not adequately consider the needs of long-term use and high-frequency operation in their structural design, resulting in weak connections between components. The connection between the positioning post and the fixture body is not robust enough, easily loosening during repeated use and causing positioning failure. Utility Model Content
