Abstract

The invention relates to a display screen detection device. The display screen detection device comprises a camera detection mechanism and a display screen detection jig. The camera detection mechanism comprises a camera mounting rack, a main camera and at least two auxiliary cameras, wherein a photographing area is prearranged at the bottom of the camera mounting rack, the main camera is arranged above the photographing area, and the auxiliary cameras are distributed on the periphery of the photographing area. The display screen detection jig comprises a jig body arranged under the photographing area, a light-emitting module, a detection probe group and a signal connector, wherein the surface of the jig body is provided with a display screen accommodating cavity, the light-emitting module is arranged at the bottom of the display screen accommodating cavity, the detection probe group is arranged on one side of the display screen accommodating cavity, and the signal connector is fixed to the jig body and is connected with the light-emitting module and the detection probe group. When display screen detection is performed, the display screen accommodating cavity is located in the shooting ranges of the main camera and the auxiliary cameras through the photographing area. By the adoption of the the camera detection mechanism and the display screen detection jig, the detection accuracy can be improved, and the problems of artificial secondary damage and relatively inaccurate detection results caused by manual detection are avoided.

Description

technical field [0001] The invention relates to a detection device, in particular to a display screen detection device. Background technique [0002] In the inspection process of electronic product display screens such as mobile phone screens, dead pixels, dark spots, bright spots, cracks and scratches are the most unfavorable factors affecting the yield of display screens. Therefore, dead pixels, dark spots, bright spots, cracks and The detection of scratches is extremely important, and the detection equipment used in the detection process is also very important. Through the control of the detection equipment, the yield and quality of the products can be well ensured. [0003] One of the current detection methods for dead pixels, dark spots, bright spots, cracks and scratches is to observe with naked eyes by inspectors with the aid of equipment similar to a magnifying glass. This kind of manual detection method, on the one hand, the detection effect is not accurate, on the...
