Embodiment Construction

[0033] (1) Online testing equipment

[0034] The detection area includes a detection conveyor belt 4, a light source 1 located on the upper side of the detection conveyor belt, a discoloration detection camera 2, and a fading detection camera 3 located on the lower side of the detection conveyor belt.

[0035] The cut photochromic polyester film 5 is located on the conveyor belt. Preferably, the conveyor belt is provided with a static electricity generating device, which can make the conveyor belt carry static electricity, so that the film can be smoothly adsorbed on the conveyor belt, and the detection accuracy can be improved.

[0036] The light source is located on the upper side of the conveyor belt, and the number of light sources can be set according to the speed of the conveyor belt and the lighting time.

[0037] The discoloration detection camera is located on the upper side of the conveyor belt and at the end of the conveyor belt, and is used to capture the discolor...

Abstract

An on-line detection method for the optical properties of a photochromic film, comprising using a conveyor belt to transport a polyester film, irradiating and collecting a discolored image on the upper side of the conveyor belt, and fading and collecting the faded image on the lower side of the conveyor belt, and sending the image to an image recognition model In this way, the areas where the optical properties of the polyester film do not meet the requirements are marked on the line. The method has the advantages of convenient operation, high precision and fast detection speed, and can meet the strict requirements of on-line detection of production lines.

Description

technical field [0001] The content of the invention belongs to material science, and in particular, relates to an on-line detection method for optical properties of photochromic polyester film production lines. Background technique [0002] With the continuous development of science and technology and the progress of human society, people's requirements for material materials are also increasing. Among various new materials, photochromic materials are favored by researchers because of their reversible color changes under the irradiation of excitation light. It has huge application prospects in the fields of optical information storage, large-area data display, smart glass and military anti-counterfeiting. [0003] Photochromism is a product that changes into another color through a series of chemical reactions when a compound is irradiated by light of a certain wavelength; its absorption spectrum changes significantly due to the change of the molecular structure or electron...
