汽车灯罩与灯体装配连接方式

摘要

汽车灯罩与灯体装配连接的质量直接关系到整个灯具的质量。根据灯罩与灯体不同材料组合的形式，文章介绍了粘胶连接式、热板焊接式、超声波焊接式、激光焊接式和摩擦焊接式5种连接方式及其优缺点，指出超声波焊接和激光焊接能够较好地达到气密性和外观要求。在未来灯具装配中，主要利用热塑性塑料分子链扩散进行塑料零件焊接，粘胶粘接将被超声波焊接、激光焊接和热板焊接等方式取代。%The assembly quality of automotive lamp hood and lamp body is directly related to the whole lamp quality. Based on The different material combination of lamp hood and body, five kinds of connection modes-viscose bonding, hot plate welding. uhrasonie wehting, laser welding and friction welding as well as advantage and disadvantage are introduced, It is indicated thai uhrasonie welding anTI laser wehling can meet the requirements of air tightness and appearance. In the future lamp assembly, thermoplaslie plastics molecular chain diffusion is used in plastic parts welding. And viscose bonding will be subs|ituted by uhrasonie welding, laser welding and hot plate welding.
