Description

CCD automatic adjustment mechanism

technical field

The invention relates to a CCD automatic adjustment mechanism, which belongs to the field of adjustment mechanism equipment.

Background technique

In the prior art, limited by the principles of liquid crystal displays, almost all mainstream liquid crystal displays have a certain "light leakage" problem. Serious "light leakage" problems will affect the quality of the liquid crystal display. Therefore, after the finished product of the liquid crystal display, It is necessary to check whether it leaks light. In the prior art, it is all manual detection. Workers adjust the brightness and contrast of the liquid crystal display to the lowest value. Then, in a dark environment, with a black background, observe the liquid crystal display up and down with naked eyes. Whether there are obvious whitening phenomena on the left and right edges, whether there is light coming through the gaps in the display frame, and finally the workers give corresponding detection results according to the observed phenomena, but manual detection will be due to many factors. There are certain deviations in the detection results, which 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. At this time, an LCD light leakage detection mechanism is needed to quickly and accurately detect light leakage of LCD products. During the light leakage detection process, a CCD mechanism is required for photo detection. When using it, the upper and lower heights of the CCD need to be adjusted to make the CCD reach the standard operating position.
