Technical Breakthroughs of Non-Standard Automation Equipment: 5 Core Technologies and Future Evolution Directions

Introduction: When Precision Demands Break Through the “Human Eye Limit”—How Technology Reshapes the Boundaries of Non-Standard Equipment

In new energy battery production, the alignment precision of pole piece lamination needs to be controlled within ±0.02mm (about 1/3 of a human hair), a physical limit for traditional mechanical positioning. A leading battery enterprise introduced “binocular vision guidance + force-controlled servo” technology, using algorithms to rectify lamination deviations in real-time, increasing the yield rate from 92% to 99.8%. This confirms a fact: the core competitiveness of non-standard automation essentially lies in the “dimensionality reduction strike” of technological breakthroughs. This article decomposes 5 core technologies to reveal how they break through the boundaries of production capacity, precision, and flexibility.
