Abstract

The invention relates to a device and method for product image quality detection. The device has a high-brightness image detection working condition, and the device comprises an imaging mechanism, a platen, a polarization assembly and a first driving mechanism; the imaging mechanism has a shooting visual angle, the polarization assembly is used for being arranged at the shooting visual angle, and the polarization assembly comprises a fixed polaroid and a self-rotating polaroid, the fixed polaroid is fixed on one side wall surface of the platen, and the self-rotating polaroid is rotationally connected to the other side wall surface of the platen; and the first driving mechanism is connected with the autorotation polaroid and is used for driving the autorotation polaroid to rotate around a rotating shaft of the autorotation polaroid in a high-brightness picture detection working condition so as to adjust the light transmittance between the fixed polaroid and the autorotation polaroid. According to the invention, the problems of low detection efficiency and large equipment size in the prior art can be solved.

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...
