Problems solved by technology

[0002] So far, the assembly of LED backlight modules has been done manually, with low precision and slow efficiency.
The LED backlight module has a multi-layer structure, reflective sheet, light guide plate, lower diffuser, prism sheet, composite film (or upper diffuser), etc. These components are all stacked directly, and it is inevitable that the components will be damaged during the assembly process. The occurrence of positional deviation will lead to various problems, such as difficult to clamp the plastic frame, film arch, light leakage, etc. These problems will lead to a decrease in production efficiency and seriously affect the quality of the backlight module
At the same time, manual assembly will also cause scratches on the diaphragm and electrostatic damage, which also affect the quality of the backlight

Abstract

A robot assembly line for an LED (Light Emitting Diode) backlight module relates to the assembly of the LED backlight module. The assembly of the conventional LED backlight is realized through manual operation, the efficiency is low, the accuracy is low, and the problems such as difficult clamping of a rubber frame, film arch, light leakage and the like are easy to occur. The invention is mainly characterized in that an air tube of a robot gripper adopts a vacuum suction manner and comprises eight independent vacuum air passages; the air tube of each assembling platform adopts a vacuum suction manner and comprises four vacuum air passages and three material platforms, each material platform can accommodate three small platforms, and each platform can be adjusted manually so as to position materials; an electrical control device adopts a PLC (Programmable Logic Controller); each colour touch screen is installed on a control cabinet; and each colour touch screen is positioned above each assembling platform respectively. The invention improves the assembling accuracy of parts, reduces the damage of films, improves the assembling efficiency, reduces the manual operation cost, and increases the production volume.
