New energy vehicles have become a phenomenal topic in 2025, especially with the recent issues surrounding autonomous driving and safety, making new energy vehicles a hot topic of discussion among everyone.

Today's technology truly changes with each passing day, constantly transforming people's lifestyles. However, the prerequisite for greater efficiency and intelligence will always be "safety". As the basic core of new energy vehicle battery packs, any defect in the cells can pose a fatal danger to the entire system. Zhengtu's new energy cell coating appearance inspection equipment strives to provide "world-class precision inspection" to safeguard the appearance quality of cells!

Part.01

Focusight Cell Coating Appearance Inspection Equipment FS-PD

This equipment is Focusight's fully automatic inspection device for the appearance of new energy prismatic/blade cells after coating, spraying, and UV treatment. Through 2D/2.5D/3D imaging technology, combined with independently developed AI software and Zhengtu's new energy cell inspection model, it realizes six-sided appearance defect detection, process traceability, and repair. By cleaning fixed positions such as explosion-proof valves/poles, it reduces the proportion of removable defects caused by processes (liquid injection/welding) and improves overall yield. At the same time, it traces and locates the links where process defects (such as coating bubbles) occur according to report tracing, guides process improvement, and improves process yield. It can be equipped with a defect repair module to repair defects such as bubbles and pole scratches.

Product Features

Efficient and Easy-to-Change Transmission Mechanism

Adopting alternating/loop line transmission mechanism, product changeover adopts replacement grippers, module components, rapid adjustment of flow channels, and simple adjustment of visual modules.

Highly Compatible System Imaging

Compatible with prismatic, blade cell coating, spraying, UV processes; covers the top surface (including poles, plastic rings, explosion-proof valves, QR codes, top patches), large surfaces, narrow surfaces, bottom surfaces, 8 edges, folded edges and corners, and window areas of the product.

Comprehensive Detection of Typical Defects

Using 2D/2.5D/3D imaging technology to conduct full-coverage imaging of the six-sided appearance of the cell, with the ability to identify and distinguish soft/hard foreign objects in the film, explosion-proof valve electrolyte, explosion-proof valve aluminum foil deformation, edge pits/damage/bubbles and other key pain point defects.

Part.03

Precision Inspection

Independent R&D: Core algorithms, software, and defect models are all independently designed and developed by Zhengtu.

Differentiation between height defects and non-height defects on film surface.

Focusight's proprietary imaging system for distinguishing soft and hard foreign objects in the film, with a discrimination rate of 99%.

Million-level film defect library AI model, covering over 98% of defects.

Explosion-proof valve electrolyte detection: Capable of imaging transparent electrolytes without missed detection.

Compatible with matte/glossy, square/circular/hexagonal/octagonal, fixed processing textures and other pole imaging and detection.

Repairable and reworkable of NG products: Classifies detected NG products to achieve diversion and blanking of repairable and reworkable defects.
