Removing detection system of the invention is for carrying out removing detection to liquid crystal display panel 90.Referring to Fig. 3, the liquid crystal surface
Plate 90 includes the first substrate 91 being oppositely arranged and the second substrate 92, the frame glue between first substrate 91 and the second substrate 92
93 and between frame glue 93 and the second substrate 92 using polyimide material make alignment film 94.First substrate 91 and
One in the second substrate 92 is color membrane substrates, another is thin film transistor base plate, is with Fig. 3 to embodiment shown in Fig. 7
Example carries out the detailed process of removing detection using removing detection system of the invention to liquid crystal display panel 90 are as follows:
Firstly, referring to Fig. 4, frame glue 93 and the second substrate 92 are removed, the position shape of the corresponding frame glue 93 of the second substrate 92
At stripping area 921.In the embodiment shown in fig. 4, when being removed frame glue 93 and the second substrate 92, actual removing circle
Face is between frame glue 93 and alignment film 94 namely frame glue 93 is removed with alignment film 94, and alignment film 94 stays in 92 table of the second substrate
Face.In other embodiments of the invention, when being removed frame glue 93 and the second substrate 92, interface is removed there is also practical
Between the second substrate 92 and alignment film 94 namely the case where alignment film 94 stays in 93 surface of frame glue.
Then, referring to Fig. 5, by the second substrate 92 be placed on heating microscope carrier 21 on, make the second substrate 92 with frame glue 93

From otherwise judgement alignment film 94 and frame glue 93 are removed.In the embodiment shown in fig. 7, due to the stripping area 921 of the second substrate 92
On no longer there is alignment film 94, therefore the collected figure of first time Image Acquisition institute is carried out to the stripping area of the second substrate 92 921
Alignment film 94 is not present as in, so that the obtained image of first time Image Acquisition and the image that second of Image Acquisition obtains are different
It causes, determines that frame glue 93 and alignment film 94 are removed namely actual removing interface is between frame glue 93 and alignment film 94 accordingly, and
In other embodiments of the invention, if alignment film 94 stays in 93 table of frame glue after being removed frame glue 93 and the second substrate 92
Face, then alignment film is not present in first time Image Acquisition institute's acquired image and second of Image Acquisition institute acquired image
94, image is consistent, determine accordingly alignment film 94 and the second substrate 92 remove namely actual removing interface be located at alignment film 94 and
Between the second substrate 92, thus when the liquid crystal display panel to narrow frame carries out removing detection, even if frame glue is Chong Die with alignment film, according to
The old removing position that can efficiently and accurately judge liquid crystal display panel, in order to be provided for the improvement of subsequent material interface adhesion
Specific direction.
