Onboard cameras are essential for ADAS features such as rearview monitoring, 360-degree surround view, and automatic emergency braking. These camera modules require clear lenses, stable structures, and dust-free internal environments to ensure high-quality imaging. Any contamination, scratches, or deformation can affect image clarity and sensor performance. Traditional welding methods may generate particles that contaminate lenses, or cause thermal deformation that misaligns internal components. DaokeDao plastic laser welding produces particle-free, low-distortion welds that protect lenses and internal sensors from contamination and damage. The non-contact process avoids surface scratches on lenses, maintaining optical clarity. It achieves a hermetic seal that meets IP67 standards, preventing fogging and water ingress caused by moisture. Our laser systems feature advanced vision alignment technology, ensuring micron-level positioning accuracy to maintain the coaxiality of lenses and sensors. This precision is critical for ensuring accurate imaging and reliable ADAS performance. The process supports small, compact camera module designs, adapting to the limited space in vehicles. With fast cycle times and consistent quality, our systems support mass production, helping automotive camera manufacturers improve product reliability and imaging performance.
