汽车前照灯玻璃(散光镜)与映光(反射镜)的接合,长期以来沿用橡胶垫圈密封(采用机械包合工艺),见图1a。但是,采用机械包合工艺存在以下缺点:(1)当玻璃外缘超厚,反射镜齿边粘上滞漆,在包合时往往发生玻璃破碎,一般产生废品率达10～20%,严重时达50%以上,造成严重的经济损失;(2)由于机械力的作用,映光(反射镜)钢皮发生变形, Automotive headlight glass (astigmatism mirror) and the reflection (mirror) of the junction, has long been sealed with rubber gaskets (using mechanical inclusion process), shown in Figure 1a. However, the use of mechanical inclusion process has the following disadvantages: (1) When the outer edge of the glass is too thick and the mirror edge sticks to the lacquer, glass breakage often occurs during the cladding process, and the rejection rate is generally 10 to 20% When more than 50%, resulting in serious economic losses; (2) due to the role of mechanical force, Yingguang (mirror) steel deformation occurs,
