Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hot pressing equipment, in particular to a high-efficiency hot pressing equipment for a light guide plate. Background Art
[0002] The light guide plate is an important component in the backlight module of the LCD screen. Its main function is to transform the LED line light source set on the side of the LCD screen into a surface light source. The principle of the light guide plate is to use the circular or square dots (ink dots, hot pressing dots, injection molding dots) on the bottom of the light guide plate to destroy the total reflection of the LED light source. When the LED light is directed to the dots, it will be reflected in all directions, the total reflection is destroyed, and the light is emitted from the front of the light guide plate. Thus, the purpose of transforming the LED line light source into a surface light source is achieved.
[0003] The common light guide plate hot pressing device on the market now adopts roller hot pressing. During roller hot pressing, the light guide plate is easily displaced and thus affects the finished product. In addition, the current hot pressing equipment performs hot pressing once and then takes out and re-places the light guide plate for hot pressing. This has a slow hot pressing speed and low production efficiency. Utility Model Content
