Then, the position of the two sets of L-shaped placement plates is adjusted by starting the second motor. Then, the positions can be adjusted to the appropriate positions according to the actual width of the flexible screen.

[0021] Then, the three sets of visual inspection modules on the inner side of the mobile ring seat move forward and backward above the curved flexible screen while also moving left and right to perform inspection operations;

[0022] When the inspection is completed, the lifting rod and two sets of L-shaped placement plates are reset, and at the same time, the three sets of movable ring seats move to one side of the flexible screen, making it convenient for the operator to remove the inspected flexible plane and replace it with a new flexible screen to be inspected.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] 1. The present invention starts the first motor to drive the reciprocating screw to rotate, so that the three groups of visual inspection modules on the inner side of the mobile ring seat move back and forth above the flexible screen while also moving left and right for inspection, which allows the visual inspection module to move at multiple angles.

For some minor defects, such as scratches and missing pixels, inspection from multiple angles can obtain more comprehensive image information, reduce the influence of factors such as light reflection and shadow occlusion on the inspection results, thereby more accurately identifying and locating defects and improving inspection accuracy.

[0025] 2. The present invention starts the electric push rod to lift the flexible screen from the middle. At this time, the second motor drives the bidirectional threaded rod to rotate, so that the two sets of L-shaped placement plates move closer to each other and continuously restrict the two ends of the flexible screen. Then, the visual inspection module on the mobile ring seat moves back and forth to continue detailed bending inspection operations on the flattened flexible screen, simulating that the flexible screen may be in different dynamic states in actual use, such as bending, folding, etc., and then utilizes the mobile performance of the visual inspection module to enable it to track the dynamic changes of the screen in real time, perform accurate inspections in different states, and ensure that the screen quality can be effectively evaluated in various usage scenarios.

[0026] 3. The present invention can start the second motor to move the two groups of L-shaped placement plates closer to each other, which can adjust the positions of the two groups of L-shaped placement plates, and then adjust them to the appropriate position according to the actual width of the flexible screen. Then, the threaded rod on the side baffle is rotated, and the limit baffle can be moved on the L-shaped placement plate. Then, it can be adjusted to the appropriate position according to the length of the flexible screen to be detected. It can be flexibly adjusted according to the specific size of the flexible screen, thereby ensuring that the detection range covers the entire screen surface, avoiding detection blind spots caused by mismatch between the screen size and the equipment, and improving the comprehensiveness of the detection. At the same time, the width and length of the flexible screen can be accurately adjusted to keep it in a stable position and posture during the detection process, so that the visual detection module on the device can accurately position and calibrate the flexible screen, thereby improving the accuracy and reliability of the detection, and ensuring the accuracy and consistency of the detection results.
