Technical field
The present invention relates to the production equipment in liquid crystal display manufacturing process, more particularly to a kind of polarizer sheet sticking detection dress
Put, also set up the polaroid attaching device for including the polarizer sheet sticking detection means.
Background technology
Thin Film Transistor-LCD (TFT-LCD, Thin Film Transistor-Liquid Crystal
Display) technique can be divided into three big flows, and first paragraph is the technique of array base palte and color membrane substrates, and second segment is orientation, liquid crystal
Filling and sealing panel process；3rd section of LCD MODULE then for polaroid, backlight and panel sectional.
In a liquid crystal display, polaroid is one of indispensable constituent components, and its purposes is that do not have script partially
The light of polarity, produces polarization, is transformed into polar biased light, therefore, and liquid crystal display can just utilize this polar biased light, add liquid crystal point
The sub torque characteristic of itself, come control light by whether and color presentation.Normally, array base palte and color membrane substrates
To after box, it is necessary to upper polaroid and down polaroid be attached respectively on array base palte and color membrane substrates, because polaroid is transparent
And its thickness very little, the situation for often occurring leakage patch polaroid.At present, the interception that polaroid is not pasted with is mainly included
Two inspection operations：
First, the visual examination process after polarizer sheet sticking process, checks for attaching polaroid using artificial visual.Due to
In the manufacturing process of liquid crystal display, automaticity is very high, in order to ensure the fluency of technological process and consider reduction people
The problem of work cost, the process can not 100% carry out visual examination, typically using fixed cycle inspect by random samples by the way of, for example
Inspect out 1 by random samples for every 200 and carry out artificial visual examination.Therefore, the inspection of the process has the possibility of missing inspection, causes not attach
The semi-finished product of polaroid are flowed into subsequent processing.
2nd, lighting test process, shows that signal causes display module display picture by applying, can detect not attach
There is the display module of polaroid.Lighting test is all carried out in the process to all display modules, i.e., 100% carries out lighting survey
Examination.However, if detection has carried out bulk production when not attaching polaroid in attaching process above in the process,
It was found that when be batch abnormalities, not only cause capacity loss, also greatly increase production cost.
Therefore, prior art has yet to be improved and developed.
The content of the invention
In view of the deficiency that prior art is present, can in real time simultaneously the invention provides a kind of polarizer sheet sticking detection means
