Abstract

The invention discloses a detection device for an optical long-focus light-resistant film, and relates to the field of light-resistant film detection.The detection device comprises a light-shielding shell, a reflection detection device is installed on the upper side in the shell, a screen changing device is installed on the lower side in the shell, a clamping device is installed between the reflection detection device and the screen changing device, and the light-resistant film is clamped on the clamping device; four rollers are arranged in the clamping device, the clamping device can roll when clamping an anti-light film, so that the anti-light film is unfolded more smoothly, the detection accuracy can be improved, the rollers are driven to rotate by the unfolding power of the rollers in the clamping device, a driving link can be saved, and the detection efficiency is improved. The control complexity is reduced, and the working process is simplified.

Description

technical field [0001] The invention relates to the field of light-resistant film detection, in particular to a detection device for an optical telephoto light-resistant film. Background technique [0002] AG anti-glare series protective film (abbreviated as AG film) is a new type of frosted film developed and improved on the basis of ordinary frosted film. Features, widely used by the public in the current market, the AG film adopts a three-layer structure, the surface layer is a frosted layer, which can effectively resist fingerprints, and it is not easy to leave marks when touched by fingers; even if sweat and stains are left, just wipe it with your hands It can be cleaned to ensure the visual effect of the device screen surface to the greatest extent. [0003] According to the characteristics of the anti-glare series protective film, add light-absorbing materials, and then use the refraction principle and reflection technology to make a telephoto optical anti-light film...
