Abstract

The invention provides a polarization angle adjusting device and a finished box detection method. The device comprises a light emitting part, a mounting part and a polarization part, wherein the mounting part is fixed on the light emitting part; the polarization part is rotatably mounted on the mounting part. When the polarization angle adjusting device provided by the invention works, a worker can rotate the polarization part to adjust an polarization angle of the polarization part, so that a polarizer polarization angle which is the same as a friction alignment angle of a cylindrical lens substrate; a polarizer does not need to be repeatedly replaced, and the adjustment efficiency of the alignment angle is effectively improved.

Description

technical field [0001] The invention relates to the technical field of polarization adjustment, in particular to a polarization angle adjustment device and a box-forming detection method. Background technique [0002] In the 2D and 3D box manufacturing process, the box is composed of the upper cover substrate and the lower column lens substrate, so that the best picture can be observed when the box is inspected in the macro inspection machine (to find the most possible error point) , will place a polarizer with polarization directions perpendicular to each other on the upper and lower substrates, and the polarizer corresponding to the lower column lens substrate will be attached to the upper surface of the backlight, or attached to an acrylic plate with good light transmission Covering the backlight, the polarization angle of the polarizer needs to be consistent with the rubbing alignment angle of the cylindrical lens substrate. [0003] The backlight is the LED light, and ...
