Introduction

As the automotive industry rapidly advances alongside security technology, onboard cameras have become increasingly prevalent, evolving into essential components for traffic safety. Serving as critical elements of the smart driving sensory layer, the reliability of vehicle cameras significantly influences the user’s driving experience. A major challenge has been ensuring these cameras are waterproof, as poor sealing can lead to water ingress, causing screen blackouts and blurred images. Positioned externally, these cameras must withstand harsh environmental conditions, including exposure to sun, rain, and car wash jets. Therefore, sealing and waterproofing are crucial. This article explores the application of Han’s Laser aluminum casing laser welding system designed to address these challenges.

Application Background

Traditional vehicle cameras use screws to attach the front and rear casings with a sealing ring to prevent water ingress. However, this method can lead to detachment and unstable sealing in various environmental conditions, impacting the camera’s functionality. Currently, the preferred method is laser welding, which creates a sealed joint at the casing interface, effectively preventing water entry.
