Background

Sheet materials such as polarizers, ultra-thin spectacle lenses, laminated composite sheets, etc. are used as important elements in displays, for example, in order to make displays bright and clear. Because the sheet material can not be easily identified with naked eyes in the polarization direction, in order to solve the problem, the common method is as follows: when the sheet material is manufactured, a certain area of the corner of the release film of the sheet material is printed with colorful patterns or characters for identifying the polarization direction, which are called vector printing.

In the production process of the polaroid, surface defects (foreign matters, bubbles, scratches and the like) and vector printing defects of the polaroid need to be detected through visual inspection equipment so as to obtain qualified flaky materials, because the deflection angle and direction of the polaroid cannot be identified by naked eyes, the traditional method always adopts manual vector printing and automatic Mark before the flaky materials are used, but the pasting procedure of the polaroid is a consistent operation, if part of the polaroids are inverted or the feeding direction is wrong, the yield of the whole production output can be reduced, the manufacturing cost is improved, and therefore effective feeding detection needs to be carried out on the flaky materials before the use.
