Positioning, fixed mount 320 is directly moved to X-axis instruction block 330 and can be achieved to screen with the position indicated by Y-axis instruction block 340
The batch detection of curtain, screen detection efficiency is high, registration.The missing inspection when method of screen detection can avoid sampling Detection
Problem screen flows to subsequent processing, finds the bad performance of screen or ray machine in advance, is easy to system integrated management, reduces rear end hair
Existing screen fraction defective, the wasting of resources is reduced, reduce product cost.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that come for one of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
