High-end manufacturing quality inspection upgrade is imminent, and traditional visual solutions encounter technical ceilings
As semiconductor manufacturing processes break through to 3nm and below nodes, the lithium electrode sheet cutting accuracy is required to reach ±5μm, and the photovoltaic film thickness uniformity error needs to be controlled within ±1%. The limitations of traditional industrial visual inspection solutions are becoming increasingly prominent. When a memory chip packaging and testing plant uses a 5-megapixel camera to detect BGA solder joints, the missed detection rate of void defects below 50μm is as high as 12%, resulting in an 8% increase in the early failure rate of terminal products; the pole sheet cutting production line of a power lithium battery company is forced to adopt a random inspection mode due to the insufficient response speed of the traditional visual system (detection speed <200fps) and cannot match the 150m/min high-speed production line, burying quality risks.
Three major technological breakthroughs to build a new system of industrial visual inspection technology
Optical system innovation: a leap from "two-dimensional detection" to "three-dimensional characterization"
3D measurement engine: industrial implementation of nano-scale morphology analysis
The built-in laser triangulation module can achieve a 3D height measurement accuracy of ±50nm. In photovoltaic perovskite film inspection, the system calculates the thickness uniformity error by scanning the nano-level fluctuations on the film surface, and improves the accuracy of film quality determination from 85% to 99.2% compared with the traditional conductivity indirect measurement method. After a display panel manufacturer adopted this system, the Mura (uneven brightness) defect detection rate of OLED screens increased by 40%, and the yield increased from 88% to 95%, saving more than 50 million yuan in annual costs.
Lithium electrode sheet: the quality gatekeeper in high-speed production
After a power lithium battery company deployed the system on the electrode sheet cutting production line, it achieved full-size detection at a speed of 150m/min. The system's "dynamic distortion compensation" technology corrects image deformation in high-speed motion in real time, making the detection rate of electrode edge burrs (required to be <20μm) reach 99.8%, an increase of 30% over traditional solutions. At the same time, by analyzing the thickness fluctuation of the electrode coating, the system provides optimization suggestions for the coating process, which increases the thickness uniformity of the electrode from ±3% to ±1.5%, and extends the battery cycle life by 15%.
Technology leads the future: from visual detection to intelligent manufacturing hub
The launch of Microview RS-A1300-GM60-M00 is not only a product upgrade, but also a reconstruction of the industrial quality inspection system. The system seamlessly connects with MES and ERP systems through open API interfaces, and has become a data hub for intelligent manufacturing. In a certain intelligent factory, visual inspection data accounts for 45% of production big data, providing core decision-making basis for process optimization, equipment maintenance, and supply chain management. The relevant person in charge of Microview said: "We are building a full-chain quality control ecosystem of 'detection-analysis-optimization-prediction'. In the future, we will use digital twins and edge AI technologies to achieve a leap from 'post-detection' to 'pre-prevention'."Email us
