LCD plate film-attaching assisting mechanism

Abstract

The invention discloses an LCD plate film-attaching assisting mechanism which comprises a fixing table and a rack. The upper portion of the rack is fixedly connected to the lower surface of the fixingtable through springs. The bottom of the fixing table is connected to a vacuum pump through a pipeline. The two sides of the rack are welded and fixed to the bottoms of side plates correspondingly. First sliding bars are in sliding connection with first sliding sleeves correspondingly. The tops of the first sliding sleeves are welded and fixed to the bottom ends of top rods correspondingly. The top ends of the top rods are welded and fixed to the two ends of a top plate correspondingly. A fixed rod, a scraping plate and a discharging roller are mounted on the lower surface of the top plate insequence. According to the LCD plate film-attaching assisting mechanism provided by the invention, LCD plates are adsorbed and fixed through negative pressure, shifting of the LCD plates during film-attaching is prevented, the scraping plate can be driven to perform film-attaching automatically by pushing the top plate through a handle, the film-attaching speed is high, it can be guaranteed thatthe LCD plates are balanced in stressing through the springs, the film-attaching effect is improved, air bubbles are effectively prevented from being generated, attaching film can be fast cut, operation is convenient, and the film-attaching quality and efficiency are improved.

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
