Detailed Description
To further understand the features and technical means of the present invention and to achieve the specific objects and functions. The invention relates to a processing method, which is described in detail in the following with reference to the accompanying drawings and specific embodiments,
referring to fig. 1 to 5, the present invention includes the steps of:
1) constructing a pre-treatment, main treatment and post-treatment disinfection system taking ultraviolet laser as a core; firstly, the handrail belt 7 passes through a pretreatment system consisting of dry warm air 13 blown by a blower 9 and a fine hairbrush 12 to carry out primary cleaning on the surface of the handrail belt. Then the hand strap 7 enters a main disinfection system consisting of two laser elliptical faculae to carry out ultraviolet laser irradiation disinfection. Finally, the handrail 7 is post-treated by a fine brush 12 and a spray 11 sprayed by a disinfection sprayer 10, and the disinfection and purification process is completed.
2) Constructing a double-light-spot disinfection optical system; the power 1 supplies power to the whole system, after the system is powered on, the ultraviolet laser generator emits continuous laser, the laser is split by the beam splitter 3, the split laser forms a laser beam parallel to the original laser after being reflected by the two reflectors 4, and the double laser beams are expanded once after passing through the beam expander 5.
