Abstract

The invention provides optical detection equipment, and the equipment comprises a carrying platform which is configured to carry a to-be-detected product; a fixed supporting part located on the side face of the carrying platform; at least one line scanning camera arranged on the fixed supporting part, and configured to scan a to-be-shot area on the surface of the to-be-detected product along a preset scanning direction so as to acquire a corresponding image; and at least one light source arranged on the fixed supporting part, one-to-one correspondence with the line scanning cameras, and configured to illuminate positions shot by the corresponding line scanning camera.

Description

technical field [0001] The present disclosure relates to the display field, in particular to an optical detection device. Background technique [0002] With the development of display technology, display products have developed from traditional planar forms to curved surfaces, curved surfaces and even spherical surfaces. Due to the characteristics of the process and the product, there are many types of defects in non-planar areas and the detection is difficult. Conventional Automated Optical Inspection (AOI) equipment appears bright bands or pure black bands when shooting curved surfaces, and cannot clearly capture product defects. , resulting in quality problems. Contents of the invention [0003] The present disclosure aims to solve at least one of the technical problems existing in the prior art, and proposes an optical detection device. [0004] In a first aspect, an embodiment of the present disclosure provides an optical detection device, including: [0005] The c...
