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...
