Pressure Control Optimization And System Design Of Laser Welding For Reversing Camera

Plastic laser welding is an efficient,accurate,and non-destructive welding method.The application of plastic laser welding technology is widespread,particularly in the automotive,electronic,medical,and other industries.Reversing cameras are increasingly being used thanks to the popularity of smart automobiles,but it is also clear that businesses need plastic laser welding technology.China is currently still developing its automated plastic laser technology and welding apparatus,and the ability of reversing cameras to weld is also advancing.While welding,pressure can be regulated to fulfill sealing requirements,protecting reversing cameras from water vapor,dust,etc.The design of the welding system and pressure optimization control are the two areas from which this paper performs research and design.The following is the content of the primary work and research:(1)Examine the main welding techniques,the reversing camera welding quality influencing factors,and the laser welding process flow.Determine the controlled object,analyze the controlled object,establish a mathematical model,clarify the control requirements and functions of the system,and propose a complete system plan.(2)In an effort to address the issues of significant time delay,nonlinearity,and timevarying pressure systems,Create a pressure system controller based on the PID control theory,the Sparrow Search Algorithm(SSA),and Dynamic Matrix Control(DMC),In MATLAB,simulation experiments are conducted on classic PID control methods,SSA-PID control strategies,DMC predictive control strategies,and SSA-DMC-PID joint control strategies,The outcomes demonstrate that the joint SSA-DMC-PID control technique provides the best control effect,quickest response time,least overshoot,and strongest resilience.(3)Create and implement the system plan based on the reversing camera’s production needs and the laser welding process flow.The hardware architecture of the system is provided by the design scheme,and hardware selection and control system circuit design are carried out in accordance with the system hardware architecture.On the basis of software functional requirements,create the entire system software.(4)Onsite commissioning should be done in the welding shop.Debugging issues should be resolved till they satisfy the reversing camera’s plastic laser welding system’s control specifications.The end result demonstrates that the laser welding pressure system for reversing cameras based on the SSA algorithm can better meet the production requirements.The laser welding equipment for reversing cameras is designed with a reasonable structure,a stable and reliable system,and some practical application value.
