AI Technical Summary
Technical Problem
The detection of pupil height and pupil distance in existing finished eyeglasses relies on manual measurement, which is inefficient, costly, and prone to human error.
Method used
Using lens inspection equipment, parallel light is projected onto the lens through an imaging system. The size scale on the projection screen and the inspection device automatically identify the pupil height and pupil distance of the lens, reducing manual intervention.
Benefits of technology
It enables rapid and accurate detection of pupil height and pupil distance, improving detection efficiency, reducing human error, and avoiding the risk of lens scratches.

Abstract
The invention discloses lens detection equipment, and relates to the technical field of lens detection, the lens detection equipment comprises a placing station, the placing station is used for placing finished glasses towards a first direction, and the lens detection equipment comprises a projection screen, an imaging system and a detection device; the projection screen is arranged towards the placing station in the first direction, and the projection screen is provided with size scales; the imaging system is used for irradiating parallel light towards the placing station along a first direction, enabling the irradiation area of the parallel light to at least cover a plurality of detection key points of lenses of the finished glasses, and projecting images of the finished glasses to the projection screen in equal proportion; and the detection device is used for detecting the pupil height and / or pupil distance of the lens according to the size scale of the projection screen and the overlapped image of the plurality of detection key points. By projecting the image of the finished glasses to the projection screen with the size scales in equal proportion, the detection device can quickly detect the pupil height and the pupil distance of the lenses according to the overlapped image, and the detection efficiency is improved.
