Problems solved by technology

[0009] Another object of the present invention is to provide a new type of heat-pressed light guide plate device. The technical problem to be solved is to improve the traditional mold by increasing the alignment line of the mold structure, which is limited by the size of the template. Due to the problem of changing different molds at the same time due to different sizes, it is more suitable for practical use

Abstract

The invention discloses a hot-pressing light guide plate device which comprises a mould structure and a stamping device. The mould structure includes a male mould and a female mould, wherein the male mould positioned above the mould structure is provided with a cushioning element and a mould plate; the cushioning element is positioned between the male mould and the mould plate, the female mould is opposite to the male mould, and the stamping device is connected on the male mould. Due to a light guide substrate (the surface of the light guide substrate is right opposite to that of the mould plate) arranged on the heating female mould, the male mould generates displacement to press against the female mould by utilizing a stamping force produced by the stamping device, so as to lead the mould structure to be in the vacuum state from the air suction state; meanwhile, the mould plate is pressed on the surface of the light guide substrate by the cushioning pressure produced by the cushioning element and the stamping force produced by the stamping device.

Description

technical field [0001] The invention relates to a heat-pressing device, in particular to a heat-pressing light guide plate device. Background technique [0002] The backlight module (Back Light Module) is one of the key components of the LCD panel, and the light guide plate in the backlight module that improves the brightness of the panel, controls the brightness uniformity, and guides the light direction is one of the important components that affect the light efficiency. The process (that is, the process, which is referred to as the process in this article) can be divided into printing and non-printing. The printing is to use screen printing (SiO 2 and TiO 2 ) The printing material is coated on the bottom surface of the light guide plate, destroying the total reflection condition of the incident light, so that the light can be evenly emitted from the light guide plate. Non-printing methods include injection molding and hot pressing methods, and non-printing methods includ...
