A light guide plate heavy pressure high temperature baking device

Abstract

The invention relates to the high-tech field of backlight modules, in particular to a heavy-pressure high-temperature baking device for a light guide plate, comprising weights, tempered glass, a light guide plate and a bottom plate of a constant temperature box. Distributed tempered glass and light guide plate, the light guide plate is arranged under the tempered glass, and two symmetrically distributed support platforms are fixedly connected to the bottom plate of the incubator. Under the premise that the light plate preparation process is basically unchanged, adding a high-temperature baking process for the light guide plate before hot pressing can effectively restore the warped raw material to a zero-warp state, greatly reducing the scrapping probability of the raw material and reducing the cost of light guide plate preparation. cost.

Description

technical field [0001] The invention relates to the high-tech field of a backlight module, in particular to a heavy-pressure high-temperature baking device for a light guide plate. Background technique [0002] The existing backlight system is mainly composed of a light source, a reflective film, a light guide plate, a double-layer cross prism and other structures. Based on the development trend of structural integration, thinning and low cost, many scientific research institutions and manufacturers at home and abroad have adopted the method of reducing the thickness of the light guide plate to reduce the cost, and can achieve the performance indicators. [0003] The mainstream of the existing light guide plate process is the hot pressing process, using methyl methacrylate (PMMA), commonly known as plexiglass, optical grade PMMA is a synthetic organic plastic with high transparency, light weight, low price, and easy molding. The mainstream material commonly used in the ligh...

Problems solved by technology

[0004] The semi-finished raw materials after cutting often warp irregularly due to the long storage time. The thinner the thickness, the easier it is to warp, which will bring serious black and white shadows during the hot pressing process, or the misalignment of the hot pressing screen and other undesirable phenomena.

As a result, these raw materials cannot be used, resulting in large-scale scrapping and greatly increasing the processing cost of the light guide plate. For this reason, we provide a light guide plate heavy-pressure high-temperature baking process and its device
