Multi-station single-vision AOI (automatic optic inspection) detection platform and detection method for flexible displays screens

Abstract

The invention belongs to the field of flexible electronic product detection associated equipment and discloses a multi-station single-vision AOI (automatic optic inspection) detection platform for flexible displays screens. The platform comprises a feeding and discharging manipulator, an up looking camera, a detection bottom board, an outer cover, a camera guide rail frame, a detection camera, a light emitting component and the like. The feeding and discharging manipulator and the up looking camera are matched mutually to guarantee that to-be-detected flexible display screens are correctly put in detection plates on the detection bottom board. The outer cover is used for providing a hermetical space for detection conditions. The camera guide rail frame and the detection camera are matched mutually to realize high-precision acquisition of front images and lateral images in different angles of the flexible display screens under the action of rotation of the detection plates. The invention further discloses a corresponding detection method. By the multi-station single-vision AOI detection platform and the detection method for the flexible displays screens, a whole multi-station flexible display screen detection process can be executed through one camera. In addition, compared with existing equipment, the platform has advantages of high precision, high efficiency, convenience in operation, high reliability, high adaptability and the like.

Description

technical field [0001] The invention belongs to the field of equipment related to the detection of flexible electronic products, and more specifically relates to a flexible display screen multi-station single-vision AOI detection platform and a detection method thereof. Background technique [0002] In recent years, with the rapid development of smart terminals, people's demand for large screens and portability of smart terminals has become increasingly strong. The development of flexible display technology and the application of flexible display screens bring more choices to the appearance changes of smart terminal products. At the same time, it is of positive significance to alleviate the contradiction of reduced portability caused by the gradual increase in terminal screen size, which is conducive to maintaining the smart terminal market. Sustained dynamic development. [0003] In the inspection process of flexible display screens, dead pixels, dark spots, bright spots, ...

Problems solved by technology

However, further studies have shown that although this method avoids the low reliability brought by the naked eye, it often needs to use multiple cameras to collect the front, side and other images of the flexible display screen during operation, and to detect them through a large number of image comparisons. Whether the flexible display is defective; Correspondingly, the use of multiple cameras will not only greatly increase the cost of detection equipment and increase the difficulty of operation, but also these parameters are easy to change compared with each other, which is often proved in practice. The quality of the collected images has a greater impact, thereby reducing the final detection accuracy
