LCD panel film pasting auxiliary mechanism

Abstract

The invention discloses an auxiliary mechanism for sticking film on an LCD panel, which includes a fixed table and a frame, the frame is fixedly connected to the lower surface of the fixed table through springs, the bottom of the fixed table is connected to a vacuum pump through a pipeline, and the machine The two sides of the frame are respectively welded and fixed to the bottom of the side plate, and the first sliding sleeve is slidably connected to the first sliding rod, and the top of the first sliding sleeve is welded and fixed to the bottom end of the ejector rod, and the ejector rod The top of the top plate is welded and fixed to the two ends of the top plate, and the lower surface of the top plate is sequentially equipped with a fixed rod, a scraper and a discharge roller. The invention absorbs and fixes the LCD board through negative pressure to prevent the LCD board from shifting during the film sticking process. Pushing the top plate by the handle can drive the scraper to automatically carry out the film sticking, the film sticking speed is fast, and the force balance on the LCD plate can be ensured by the spring to improve the film sticking effect , effectively avoid the generation of air bubbles, can quickly cut the film, easy to operate, and improve the quality and efficiency of the film.

Description

technical field [0001] The invention belongs to the technical field of film sticking devices, and in particular relates to an auxiliary mechanism for film sticking of an LCD panel. Background technique [0002] The structure of the LCD is to place a liquid crystal cell between two parallel glass substrates, set a TFT (thin film transistor) on the lower substrate glass, and set a color filter on the upper substrate glass, and control the liquid crystal molecules by changing the signal and voltage on the TFT. Rotate the direction, so as to achieve the purpose of controlling whether the polarized light of each pixel is emitted or not to achieve the display purpose. In order to protect the LCD panel, a layer of protective film is usually pasted on the surface of the LCD. The existing film sticking mechanism usually fixes the LCD panel by clamping and fixing, which is easy to damage the LCD panel. When equalizing, it cannot be automatically balanced, resulting in air bubbles in ...

In order to protect the LCD panel, a layer of protective film is usually pasted on the surface of the LCD. The existing film sticking mechanism usually fixes the LCD panel by clamping and fixing, which is easy to damage the LCD panel. When equalizing, it cannot be automatically balanced, resulting in the existence of air bubbles in the film, which affects the quality of the film
