Abstract

This invention discloses an LED backlight brightness detection device and method, relating to the field of LED backlight detection technology. It includes a detection platform with a detector fixedly connected to its upper surface. A sliding groove is symmetrically formed on the upper surface of the detection platform. It also includes an alternating detection mechanism and an automatic adsorption mechanism. The alternating detection mechanism includes a rotating shaft rotatably connected to the center of the upper surface of the detection platform. A connecting plate is fitted onto the outer surface of the rotating shaft, and support plates are fixedly connected to both sides of the connecting plate. The alternating detection mechanism is used to continuously improve the sealing of LED backlight brightness detection, maintaining the sealing of the material during the LED backlight detection process and avoiding interference from external light sources that could affect the detection effect. The moving frame drives the rack plate and transmission gear to automatically link the rotating shaft, connecting plate, and other components, eliminating the need for manual operation and making the entire material conveying process smooth and efficient.
