It comprehensively covers mainstream high-demand scenarios, including autonomous driving perception, surround-view parking, in-cabin safety monitoring, and blind-spot detection, and supports on-demand customization to achieve flexible, mixed-model production on a single AA line.

II. Industry Bottlenecks: Automotive Camera Mass Production Faces Multiple Real-World Challenges

Currently, visual perception modules like binocular and trifocal cameras are exploding in popularity within the autonomous driving sector, surging market demand for scale. However, as modules iterate toward higher pixel counts, multi-lens setups, and ultra-wide angles, the shortcomings of traditional production lines have completely come to a head: difficulty in mixed-model production, substandard precision, and persistently high costs. Mass production capacity cannot keep pace with the speed of product iterations, trapping enterprises in a dilemma.

Key challenges include:

● Manufacturing scalability constraints: Difficulty in supporting multi-product mixed-line production under fast iteration cycles, resulting in limited throughput flexibility

● Precision and stability issues: AA misalignment, equipment fluctuation, and thermal variation lead to rework and yield loss in mass production

● Process fragmentation: Inconsistent workflows and non-standardized process integration reduce overall production reliability

Under the industry trends of high product variety, small batches, and rapid iteration, traditional production lines can no longer support automotive-grade mass production requirements. How can the industry break through this impasse?

Targeting these core industry pain points, Yanding has leveraged its deep technical expertise in optical testing and precision assembly. By achieving complete self-reliance in core technologies, Yanding combined its self-developed collimators, high-speed frame grabbers, and core AA algorithms to launch an integrated, flexible AA active alignment production line. The equipment can flexibly configure the optimal optical environment and process parameters based on lens characteristics, stably enabling the mixed-model production of various module types, including binocular, trifocal, and ultra-wide-angle cameras. It solves the bottlenecks of high precision, high stability, and high adaptability through hard-core technology.

From plasma cleaning, white field pre-testing, and high-precision glue dispensing, to AA active alignment and dual-stage curing, Yanding has connected the critical steps of the AA process chain. This achieves highly efficient collaboration across production sections, reduces quality losses, and solves the challenge of multi-variety mixed-model production with the advantages of low investment, high efficiency, and high yield, helping high-end automotive visual perception modules scale up stably and smoothly.
