Abstract

The invention relates to the technical field of liquid crystal display panel manufacture, and discloses a liquid crystal display COF (chip on film) bonding semi-automatic device which comprises a vacuum absorption mechanism and a pressing mechanism. A gravity center of the vacuum absorption mechanism approaches to one side of the pressing mechanism, flatness of large-size liquid crystal displays is ensured, and the pressing mechanism comprises a printed circuit board pressing module and a flexible printed circuit board pressing module. According to the device, straightness of printed circuit boards is monitored by a first alignment camera, relative positions of the liquid crystal displays and the printed circuit boards are adjusted by a second alignment camera and a motor transmission control mechanism, relative positions of the liquid crystal displays and flexible printed circuit boards are adjusted by a flexible printed circuit board adjusting component, the device solves the problems that a Gate side and a Source side are difficultly and simultaneously pressed, large-size liquid crystal displays are difficultly pressed when the flatness of the liquid crystal displays is ensured,and position accuracy is difficultly ensured by manually adjusting the positions of the liquid crystal displays in the prior art.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel manufacturing, and discloses a liquid crystal display COF press semi-automatic equipment and a pressing process thereof. Background technique [0002] At present, LCD panels have been widely used. The imaging core of the LCD panel is a piece of laminated glass. The upper side of the glass is connected to process Source signals, commonly known as X modules; the side is connected to process Gate signals, commonly known as Y modules. [0003] The charges and control signals required for driving the pixels of the LCD panel come from the external printed circuit board (PCB), which needs to be transmitted to the LCD panel through the flexible circuit board COF (Chip On Film), that is, the flexible circuit board. One end of the connection is connected to the liquid crystal display LCD (Liquid Crystal Display), and the other end is connected to the printed circuit board. The liquid crystal d...
