Addressing the extreme demands for product consistency, process stability, and production efficiency in the industrial manufacturing sector, Wenzhou Yihe Intelligent Technology Co., Ltd. has launched a vision inspection system covering core processes such as metal processing, electronic assembly, and injection molding. Utilizing laser interferometry technology, it achieves precision part dimensional inspection accuracy of ±0.002mm. Combined with a self-developed multi-sensor fusion algorithm, it performs sub-micron-level quantitative analysis of gear tooth profile deviation and bearing raceway roughness (Ra≤0.1μm), meeting ISO 2768 tolerance standards. In the electronics manufacturing field, the 3D AOI inspection system uses structured light scanning to detect the coplanarity of BGA chip solder joints, achieving a height deviation recognition accuracy of ±5μm, helping companies like Huawei and OPPO reduce PCBA defect rates to below 0.1%. For the injection molding industry, it has devel
