Abstract

The invention relates to the technical field of lenses, and discloses an automatic focusing detection system which comprises a detection device and a carrying device, the detection device comprises a detection box body, a relay lens, an image card distance adjusting device and a light-emitting component, the relay lens is arranged in the detection box body, the image side end of the relay lens faces the outside of the detection box body, and the object side end of the relay lens faces the inside of the detection box body; the graphic card distance adjusting device is arranged in the detection box body and used for installing a detection graphic card and adjusting the distance between the detection graphic card and the object side end of the relay lens, the light-emitting component is arranged in the box body and used for providing light for the detection graphic card, and the carrying equipment is arranged on one side of the detection equipment and used for carrying the detection graphic card. The carrying equipment is used for moving the to-be-detected material to a detection position, and the detection position is that the imaging optical axis of the to-be-detected material coincides with the optical axis of the relay lens, and the object side end of the to-be-detected material faces the position of the image side end of the relay lens. By adopting the automatic focusing detection system provided by the embodiment of the invention, the labor cost can be saved, and the detection precision is improved.

Description

technical field [0001] The present invention relates to the technical field of lenses, in particular to an automatic focus detection system. Background technique [0002] Electronic devices on the market (such as mobile phones, tablets, etc.) generally use auto-focus camera modules. The camera modules need to perform auto-focus detection before leaving the factory to ensure a high yield. When detecting the automatic focusing of the camera module, detection charts at different distances are usually taken under different brightness conditions, so as to determine whether the automatic focusing of the camera module meets the requirements through the obtained image information. [0003] However, the current autofocus detection of the camera module is semi-automatic, which requires manual participation in the detection, with high labor costs and low detection accuracy. SUMMARY OF THE INVENTION [0004] The embodiment of the invention discloses an automatic focus detection syste...
