With developing rapidly for domestic and international auto industry, the requirement more and more higher to car light.As New pattern headlight long-and-short distant light weight
The lens of component are wanted, by increasingly extensive concern and popularization and application.Lens and support are welded with various ways, common are
Rivet hot weldering, ultrasonic bonding etc..Rivet hot weldering needs integrally to heat lens and support, easily produces thermal deformation, causes welding not
It is good.Ultrasonic welding is that high-frequency electrical energy is converted to high-frequency mechanical vibrational energy using supersonic transducer, under pressure,
Friction generates heat for lens and the generation of support contact surface, melts muscle melting engagement.It is high and super that face precision is melted in supersonic welding requirement
Sound wave there are certain requirements to welding material and operating environment, therefore use has certain limitation.
Lens and support use laser welding, its soldered precision size, firm welding, because not needing direct Contact welding fitting,
The consume and deformation of equipment can all minimize, and product stress without friction and thermal stress so that cause thermal damage and thermal deformation subtract significantly
It is small.The solderable material category of laser welding is big, and can also be bonded with each other various dissimilar materials, have a wide range of application.
Plastics laser welding uses robotic laser welding manner more at present, i.e., laser is arranged on robotic arm, control machine
Device hand-motion laser is run along solder side track, and the speed run by the power and mechanical hand that control laser is welded to control
Connect quality.This welding manner is higher to mechanical design requirements, and coordinated signals are complicated, and are easily produced in mechanical hand welding process
Stress deformation.
