Abstract

The present application relates to a device and method for product image quality detection, which has a high-brightness picture detection working condition, and includes an imaging mechanism, a platen, a polarizing assembly and a first driving mechanism, and the imaging mechanism has a shooting angle of view. The polarizing assembly is used to place the shooting angle. The polarizing assembly includes a fixed polarizer and a rotating polarizer. On the other side wall of the platen; the first driving mechanism is connected with the self-rotating polarizer, and is used for: driving the self-rotating polarizer to rotate around its own rotation axis when it is in the high-brightness picture detection working condition , to adjust the light transmittance between the fixed polarizer and the rotating polarizer. The application can solve the problems of low detection efficiency and large equipment volume in the related art.

Description

technical field [0001] This application relates to the technical field of appearance inspection based on AOI (Automated Optical Inspection), in particular to a device and method for product image quality inspection. Background technique [0002] With people's pursuit of the ultimate screen display effect, conventional display technology can no longer meet the needs of future development, and new display methods are gradually entering people's lives, such as the higher-tech Micro LED (micro light-emitting diode, grain size Between 50um and pitch within 1mm) and Mini LED. Compared with conventional LEDs (Lighting Emitting Diodes, or light-emitting diodes), LCDs, and OLEDs, Micro LEDs and Mini LEDs have excellent brightness, high luminous efficiency, low energy consumption, high response speed, high contrast, self-illumination, and long service life. The advantages of ultra-high resolution and color saturation are known as a new generation of display technology that disrupts t...
