Abstract

An integrated unit of light guide plate and reflection sheet consists of a contact roller and an operation platform. It features that contact roller is set at one side of platform, operation platform is used to realize accurate positioning when light guide plate fits on reflection sheet, contact roller is used to produce pressure on reflection sheet set at side of light guide plate to make reflection sheet fit on light guide plate.

Description

【Technical field】 [0001] The present invention relates to a liquid crystal display (Liquid Crystal Display, LCD) manufacturing device, in particular to a combination device. 【Background technique】 [0002] The backlight system (Backlight System) of LCD mainly includes light guide plate (Light Guide Plate, LGP), light source, reflector film (Reflector Film) and prism film and other components. At the light incident surface, the reflection sheet and the prism sheet are respectively placed near the bottom surface of the light guide plate and the light exit surface. In addition, in order to prevent light from leaking from the remaining sides of the light guide plate, a reflective sheet is also attached to the side of the light guide plate. [0003] In the prior art backlight system assembly production line, manual alignment and folding are used to attach the light guide plate and reflector. At the same time, its bonding efficiency is not high. 【Content of invention】 [0004...
