Abstract

The invention discloses an AOI (automatic optic inspection) device. The AOI device comprises a support, a camera mounted at the upper part of the support and a front light generation mechanism mounted below the camera, wherein the front light generation mechanism comprises a hollow barrel, a hollow bracket fixed at the lower part of the barrel, light sources arranged on the bracket and a dome arranged above the barrel, and a through hole corresponding to a lens of the camera is arranged in the center of the upper part of the dome. The AOI device is simple in structure, the dome scatters colored light generated by the lower light sources, compound light uniform in all directions is formed through repeated reflection in the barrel, so that light irradiating on a battery piece located below the barrel is consistent in all directions, the camera captures a clear picture, and the detection result is more accurate.

Description

【Technical field】 [0001] The invention relates to the technical field of solar energy devices, in particular to an AOI detection device with simple structure and capable of releasing uniform colored light. 【Background technique】 [0002] Solar cell is an energy-saving component with silicon as the main material. Surface defects may appear during its processing and transportation, which will seriously affect the performance and life of solar cells. Therefore, solar cells must be optically inspected to identify tiny cracks or uneven colors on the surface, so as to find and deal with problematic products in time. In the prior art, the color detection of solar cells is accomplished by an automatic optical inspection (Automatic Optic Inspection, referred to as AOI) device. The core of the inspection system is to provide uniform illumination in all directions, so that the appearance of the product can be clearly captured by the camera. In the past equipment, it is more complicat...
