Abstract

The invention discloses a laser stripping method applied to an automobile lamp and belongs to the technical field of laser stripping. The stripping method includes the main stripping processes that firstly, automobile lamp paint spraying treatment is conducted; secondly, acid treatment is conducted; thirdly, nano bombard treatment is conducted; and fourthly, auxiairy laser stripping is conducted.Nano particles reducing laser energy are added during bombard treatment, a sucrose auxiliary solution is extruded during laser stripping, and therefore the damage of laser to an automobile lamp is further reduced. By means of the adopted laser stripping method, the laser stripping efficiency can be effectively improved, in addition, an automobile lamp base material is protected, and the damage rate of the automobile lamp base material is reduced during laser stripping.

Description

technical field [0001] The invention relates to the technical field of laser stripping, in particular to a laser stripping method applied to vehicle lights. Background technique [0002] From the invention of the car to the present, the car lamp integrates the appearance and lighting function, occupying a place in the function of the whole vehicle. With the development of the times and the transformation of the automotive industry, car lights are surpassing traditional lighting needs. With the improvement of people's income level, people's consumption concepts and travel methods have undergone major changes. When choosing a car, more consumers not only pay attention to its performance, but also pay more attention to the appearance of the car. Car lights are to cars what eyes are to people. The use of car lights is not only directly related to safe driving, but also the shape of car lights will affect the appearance of the whole car. Therefore, car lights have two functions:...
