LCD panel film pasting auxiliary mechanism

Abstract

The invention discloses an LCD panel film pasting auxiliary mechanism. The LCD panel film pasting auxiliary mechanism comprises a fixing platform and a frame. The frame is fixedly connected to the lower surface of the fixing platform through a spring. The bottom of the fixing platform is connected to a vacuum pump through a pipe. Two sides of the frame are respectively welded and fixed to the bottoms of side plates. First sliding rods are slidingly connected to first sliding sleeves. The tops of the first sliding sleeves are welded and fixed at the bottoms of ejector rods. The top ends of the ejector rods are welded and fixed on the two ends of an ejector plate. The lower surface of the ejector plate is orderly provided with a fixing rod, a scraper plate and a discharge roller. A LCD suction plate is adsorbed and fixed by negative pressure so that LCD plate shift in film pasting is prevented. The ejector plate is pushed manually to drive the scraper plate so that the film is automatically pasted. The LCD panel film pasting auxiliary mechanism has a fast film pasting rate. The spring can ensure load balance of the LCD plate so that film pasting effects are improved and bubbles are effectively avoided. The mechanism can fast cut a film, is easy to operate and improves film pasting quality and efficiency.

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
