Automatic film pasting device for LCD display screen

Abstract

The invention discloses an automatic film pasting device for an LCD display screen. The automatic film pasting device comprises a conveying assembly, a conveying belt is arranged in the conveying assembly, a clamp assembly is arranged on the conveying belt, the clamp assembly comprises a clamp bottom plate, a clamping plate is arranged on the clamp bottom plate, the LCD display screen is arrangedin the clamping plate, and a film pasting assembly is arranged on one side of the conveying assembly; and the film pasting assembly comprises a film collecting rotating shaft and a film discharging rotating shaft, film pressing rotating shafts distributed in an array mode are arranged on the conveying belt, first air cylinders distributed in an array mode are arranged below the film pressing rotating shafts, and a pressing-fit assembly is arranged on one side of the film pasting assembly. The automatic film pasting device is reliable in structure and practical in function, the LCD display screen is convenient and simple to fix during film pasting, a static electricity eliminating rod and a magnetic rod are arranged in the film pasting assembly, static electricity can be effectively eliminated before film pasting, powdery and granular ferromagnetic impurities are removed, the film pasting speed is high, automatic design is adopted, errors are small, the labor cost is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of LCD display screens, in particular to an automatic film sticking device for LCD display screens. Background technique [0002] LCD display is an active matrix liquid crystal display driven by thin film transistors. It mainly uses current to stimulate liquid crystal molecules to generate points, lines, and surfaces to form a picture with the back lamp tube. IPS, TFT, and SLCD are all subcategories of LCD. Under the action of an electric field, the LCD display uses the change in the alignment direction of the liquid crystal molecules to change the light transmittance of the external light source to complete the electro-optical conversion, and then uses the different excitations of the R, G, and B three primary color signals to pass the red, green , blue three-color filter film, complete color reproduction in time domain and space domain, thin body, save space Space, power saving, no high temperature, it is a low po...

AI Technical Summary

Problems solved by technology

Before packing the LCD display screen, a protective film needs to be pasted on the glass surface. The existing film pasting device is slow in efficiency, prone to size deviation and ferromagnetic impurity pollution, and there is no static elimination device when pasting the film. In view of this situation, a LCD is proposed Display automatic film sticking device
