Rotary multi-environment AOI detecting device and method

Abstract

The invention discloses a rotary multi-environment AOI detecting device and a rotary multi-environment AOI detecting method. The rotary multi-environment AOI detecting device comprises a plurality ofscreen detecting stations, a detecting light source, a screen moving device, an image acquisition device and a data processing device, wherein each screen detecting station is configured to have different detection environments suitable for detecting specific screen defect types; the screen moving device moves detected screens to the screen detecting stations synchronously; the image acquisition device acquires all-station images of the detected screens at respective current screen detecting stations, so that each image contains a plurality of image regions corresponding to different screen detecting stations; the screen moving device moves the detected screens to the respective next screen detecting stations after each image acquisition; and the image acquisition device re-conducts the image acquisition in the next round of multiple detection environments until the detected screens traverse detection of the different detection environments. The rotary multi-environment AOI detecting device and the rotary multi-environment AOI detecting method greatly improve the utilization rate of the image acquisition regions, and reduce the requirements for image acquisition environments.

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 ...
