A light guide plate assembly device

Abstract

The invention relates to the technical field of auxiliary devices for machining electronic products, in particular to a light guide plate assembling device. The light guide plate assembling device comprises an installation frame, a printed circuit board (PCB) mechanism arranged on the installation frame, a light guide plate manipulator arranged on one side of the PCB mechanism, and a pressing mechanism used for pressing a PCB and a light guide plate together. The PCB mechanism comprises a rotary base, a first rotary platform, a second rotary platform and a rotation driving device, wherein both the first rotary platform and the second rotary platform are arranged on the rotary base, and the rotation driving device is used for driving the rotary base to rotate. During practical application, the PCB is placed on the first rotary platform, the first rotary platform is rotated to the second rotary platform by the rotation driving device, and the second rotary platform is rotated to the position of the PCB at the same time; the light guide plate manipulator grabs the light guide plate and assembles the light guide plate and the PCB together in a butt joint mode, and then the PCB and the light guide plate are tightly pressed through the pressing mechanism. The light guide plate assembling device is compact in structure; automatic assembly is adopted, so that the labor cost is reduced, the assembling efficiency is improved, and the light guide plate assembling device has extremely high practicability.

Description

technical field [0001] The invention relates to the technical field of electronic product processing auxiliary devices, in particular to a light guide plate assembly device. Background technique [0002] Backlights are widely used in touch screens, LCD / LCM, mobile phones, tablet computers, GPS, solar cells and other industries, and generally include light bars, light guide plates, diffusion films, enhancement films, and black and white films. [0003] In the backlight assembly process, the light guide plate and the PCB (light strip) are generally assembled first, and then the light guide plate with the PCB installed and the semi-finished backlight source are assembled. In the traditional process, the assembly of the light guide plate and PCB is manually operated, the labor intensity of the workers is high, the assembly accuracy is poor, and the efficiency is low. Different operators have different levels of assembly products, which makes it difficult to unify the quality of ...
