A kind of rotary multi-environment aoi detection device and method

Abstract

A rotary multi-environment AOI detection device and method, the device includes a plurality of screen detection stations, detection light source, screen moving device, image acquisition device and data processing device, each screen detection station is configured with a specific The screen moving device will move the screen under test to each screen detection station synchronously, and the image acquisition device will perform full-station image acquisition on the screen under test at the respective current screen detection stations, so that each Each image contains a plurality of image areas respectively corresponding to different screen detection stations. After each image acquisition is completed, the screen moving device moves the screen under test to the respective next screen detection station, and the image acquisition device performs the next screen detection station again. Image acquisition in multiple detection environments, until the screen under test traverses the detection of different detection environments. The invention greatly improves the utilization rate of the image acquisition area, and reduces the requirement on the image acquisition environment.

Description

technical field [0001] The invention relates to optical detection technology, in particular to a rotary multi-environment automatic optical detection (AOI) detection device and method. Background technique [0002] The single-camera multi-station mobile phone screen detection device integrates the image acquisition environment of multiple stations into a single image acquisition platform. Compared with the multi-camera screen inspection device, it has the following advantages: the number of cameras is reduced, which can reduce the failure rate of equipment, and correspondingly improve the robustness of the overall equipment; the interaction process between cameras is removed, and the overall inspection process is reduced. The disadvantage is that, due to the need to keep the image acquisition environment of each station the same, in the strip lighting environment, a longer light source is required, and, in the state of pressure film sealing, because the pressure required by ...
