Abstract

The invention discloses an AOI indentation detection system and method. The AOI indentation detection system comprises a shell, a light splitting adjusting button, a polarization adjusting button, a TDI camera and a DIC prism. The DIC prism comprises a first prism and a second prism; the TDI camera and the DIC prism are arranged in the shell at intervals; the light splitting adjusting button is connected with the DIC prism and used for adjusting the distance between the DIC prism and the TDI camera. The polarization adjusting button is connected with at least one of the first prism and the second prism and used for adjusting the distance between the first prism and the second prism. The existing indentation detection technology mainly has the defects of large volume, high cost, low efficiency, unclear imaging, incapability of flexible adjustment and the like, but the method can realize flexible adjustment, utilizes the tiny change of the thickness of the prism to cause the tiny change of the optical path difference, generates a better interference effect, further realizes better user observation experience, and is suitable for popularization and application. And quantitative analysis with higher precision is facilitated.

Description

technical field [0001] The invention relates to the field of intelligent optical detection, in particular to an AOI indentation detection system and method. Background technique [0002] With the development of industrial modernization, traditional manual inspection can no longer meet the requirements of technological development, and visual intelligent inspection represented by AOI inspection has become the general trend. [0003] The full name of AOI is Automatic Optical Inspection, which is based on the optical principle to make the particles clearer through the ultra-high pixel lens to detect common defects in production. AOI testing is a new type of testing technology. At this stage, the domestic AOI testing equipment market is still in the stage of rapid growth. Domestic companies are gaining a firm foothold in the low-end market and actively seizing the high-end market. [0004] In the actual process of R&D and production, the existing AOI inspection technology still...
