Rotating mechanism is Z-type rocking bar, and one end of the Z-type rocking bar is fixedly connected with the rotary shaft.
8. the test method that a kind of quickly detection AR glass surface is stained with grey performance, it is characterised in that: the test method is using power 1
It is carried out to test device described in 7 any one, comprising the following steps:
Step S1, the sample of dust by the drying of constant weight is fitted into container, and sample of dust capacity is made to account for overall vessel volume
30%-60%, then weighed with assay balance to equipped with the container of sample of dust, total weight X1, spare；
Step S2, AR glass to be detected is installed to clamping plate, then rotating mechanism drives clamping plate to rotate around rotary shaft
So that AR glass is in horizontality, and make the surface to be measured of AR glass downward；Then, sample of dust will be equipped with using magnet
Container is fixed on the surface to be measured of AR glass, and the open end of container is towards the surface to be measured of AR glass, to guarantee container and AR
Glass surfacing to be measured fully contacts；
Step S3, centered on container, AR glass is driven to do 360 degree rotation by rotating mechanism, it is fast after rotation speed is first slow, make
Sample of dust in container can be contacted with the surface to be measured of AR glass completely；
Step S4, so that AR glass is back to horizontality after the completion of rotation, then vertically remove container, it is avoided to wait for AR glass
It surveys surface and opposite sliding occurs；
Step S5, it is weighed using assay balance to the container equipped with remaining sample of dust, total weight X2, and calculate appearance
Device before testing after weightless M=X1-X2；Then calculate unit area AR glass surface absorption sample of dust quality be
M/A, wherein A indicates the opening area of container；
Step S6, step S1 to S5 is repeated, is repeatedly tested under the same conditions, the average value of M/A is taken, AR glass can be characterized
It is stained with grey performance in glass surface.
9. the test method that a kind of quickly detection AR glass surface according to claim 8 is stained with grey performance, it is characterised in that:
In step S3, AR glass does 360 degree rotation 3-4 weeks, and the rotation speed before AR glass surface is completely covered in sample of dust
For (8-12) °/S, the rotation speed after AR glass surface is completely covered in sample of dust is (40-60) °/S.
10. a kind of quickly detection AR glass surface according to claim 8 is stained with the test method of grey performance, feature exists
In: the average particle size of sample of dust >=200 mesh, test temperature are 23~27 DEG C, and humidity is less than 50%RH.
