LCD light leakage detection mechanism

Abstract

The invention relates to an LCD light leakage detection mechanism. A lifting adjusting mechanism and a rotating disc mechanism are installed on a bottom plate. Carrier devices are installed on the rotating disc mechanism. A CCD supporting bottom plate of a CCD adjusting mechanism is connected with nuts on a left lead screw and a right lead screw of the lifting adjusting mechanism. The CCD supporting bottom plate of the CCD adjusting mechanism is fixedly connected with an upper seal box of a seal box mechanism through four reinforcement ribs, the CCD adjusting mechanism is used for adjusting the vertical height of a CCD, the seal box mechanism is used for guaranteeing that an LCD is always in a closed and light-proof environment, and the lifting adjusting mechanism is used for adjusting the vertical height of the CCD adjusting mechanism and the seal box mechanism. A taking and placing station and a detection station are arranged on a rotating disc of the rotating mechanism, the carrier devices are installed on both the stations respectively, the two stations can achieve continuous detection, and whether the LCD leaks light or not is detected through CCD photographing. The LCD light leakage detection mechanism is simple in structure, convenient to operate and capable of rapidly and accurately detecting whether the LCD leaks light or not.

Description

Technical field: [0001] The invention relates to the field of detection mechanism equipment, and more particularly to an LCD light leakage detection mechanism. Background technique: [0002] Limited by the principle of liquid crystal display, almost all mainstream liquid crystal displays will have a certain "light leakage" problem. Serious "light leakage" problems can affect the quality of the LCD display. Therefore, after the liquid crystal display is produced, it needs to be checked for light leakage. In the prior art, it is all manual detection. Workers adjust the LCD's brightness and contrast to the lowest possible values. Then, in a dark environment, with black as the background, observe with the naked eye whether the upper, lower, left, and right edges of the LCD display have obvious whitening phenomenon, and whether there is light leaking through the gaps in the display frame. Finally, workers give corresponding test results according to the observed phenomenon. ...

Problems solved by technology

[0003] However, due to various factors, manual inspection will lead to certain deviations in the inspection results, which will affect the production efficiency and increase the production cost of the company.

At the same time, the manual detection operation is inconvenient, the speed is slow, the workers are prone to fatigue, and the work efficiency is low.
