Abstract

The invention provides a liquid crystal panel delamination detection device and method, the device comprising: a base, a mobile platform, a natural light source camera assembly, a first ultraviolet light source camera assembly, a second ultraviolet light source camera assembly, an upper light source assembly and a backlight Assemblies, the mobile carrier adopts an air-floating platform, and the mobile carrier is set above the base. The natural light source camera assembly, the upper light source assembly and the first ultraviolet light source camera assembly are all located on one side of the mobile carrier. The first ultraviolet light source camera assembly and the second The two ultraviolet light source camera components are symmetrically arranged with the liquid crystal panel as the axis, and the second ultraviolet light source camera component and the backlight source component are located on the other side of the liquid crystal panel; wherein, the upper light source component includes a first natural light source component and a first ultraviolet light source component, The backlight source assembly includes a second natural light source assembly and a second ultraviolet light source assembly. The invention can automatically distinguish the defects on the surface of the liquid crystal panel and the defects inside the liquid crystal panel, thereby improving the detection efficiency.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal panel delamination detection equipment, in particular to a liquid crystal panel delamination detection equipment and method. Background technique [0002] The typical composition of LCD (Liquid Crystal Display) liquid crystal screen is TP (Touch Panel, touch screen) glass, upper polarizer, color filter, liquid crystal layer, TFT (Thin Film Transistor, thin film transistor) substrate, lower polarizer from top to bottom and backlight. With the development of LCD technology, it has quickly become the leading role in the display market due to its characteristics of high resolution, small size, light weight, no radiation, flat panel and low power consumption. From mobile phones to portable game consoles, from industrial equipment to artificial LCD is ubiquitous in many fields such as operating platform to bank self-service equipment ATM (Automatic Teller Machine). Therefore, it becomes...
