 especially reflected in:

Core technology: The Lyric AVI inspection machine equipped with high-precision cameras and self-developed photometric 3D reconstruction technology, can accurately identify more than 50 kinds of subtle defects, including pinholes, liquid leakage, packaging damage and other defects, and has a self-learning function, with the accumulation of data to optimise the inspection model, to improve the recognition accuracy to the industry's leading level.

Million level database and advanced algorithms: The Lyric AVI inspection machine adopts 2D, 2.5D and 3D comprehensive inspection scheme to accurately quantify the defect information, and through the million-level defect database and industry-advanced AI+CV algorithm system, it achieves fast and accurate detection of all kinds of battery cell defects.

Real-time monitoring and intelligent decision-making: The system monitors production yield changes in real time, supplemented by detailed statistical analysis and MES system traceability functions, providing strong data support for production line process optimisation and intelligent quality control, and helping the enterprise to achieve continuous improvement of yield.

New Defect Response Mechanism: In the face of new defect challenges, the Lyric AVI inspection machine has established a rapid response process. Once a sufficient number of new defect samples are acquired, the AI model can be updated to the field within 60 minutes and ensure that defects that are consistently judged as NG by multiple visual inspectors can be stably detected without interrupting production when updating the model.

[AVI detection machine function configuration and performance parameters]
Equipment layout and functions: The Lyric The AVI inspection machine is responsible for the automatic loading of cells, inspection for cosmetic defects, and sorting and discharging of cells according to OK and re-inspection standards. With a footprint of approximately 3500mm x 2500mm x 2600mm, the machine can be operated efficiently by a single operator.

Key Performance Indicators: The machine strictly controls the Major leakage rate to 0% and sets a clear threshold for the minor leakage rate to ensure that the inspection results are better than manual inspection. At the same time, the over detection rate of the equipment is also strictly limited to ensure the fair judgement of each piece of battery cell.Lyric AVI inspection machine has excellent automation capability and up to 32PPM production capacity, and the equipment downtime rate is less than 3%, which demonstrates the excellent reliability and stability.

The Lyric AVI inspection machine shows obvious advantages in automation level, inspection tempo, defect detection types, leakage and over detection control, and compatibility with special application scenarios such as soft-packed CE cells. Especially based on the strong support of the multi-million database, Lyric AVI inspection machine in the field of data-driven intelligent inspection is far ahead.

【 Addressing customer pain points and creating value】
Precision testing and full chain quality control: The Lyric AVI inspection machine applies high-precision camera and self-developed photometric stereo 3D reconstruction technology to carry out comprehensive and detailed inspection on the battery cell, effectively capturing minute defects and greatly improving the accuracy of inspection. Meanwhile, through the standardised and automated quality inspection process, it prevents the circulation of defective products at the source, which strongly strengthens the enterprise's quality management in the whole process from raw materials to finished products, and guarantees the reliable and uniform quality of the battery cell.

Intelligent quality management: Integration of intelligent data management and feedback systems, real-time recording and categorisation of test results, automatic generation of detailed reports, to facilitate enterprises to track the source of the problem, optimise the process and prevent batch quality problems. With the help of big data analysis, we can quickly adjust and optimise the parameters of production lines to achieve real-time prevention and continuous improvement.

High-efficiency production, optimising cost and efficiency: With its innovative and flexible design and easy integration features, the AVI inspection machine from Lee & Young successfully realises automated loading, accurate inspection and intelligent screening of battery cells, significantly reducing manual intervention, optimising the overall production pace, effectively reducing work intensity, and effectively promoting the implementation of lean production and the goal of zero error. It also plays an active role in cost saving by avoiding the cost of maintenance and return due to production problems, and its excellent high-speed and accurate inspection performance also improves the overall production line efficiency, ultimately providing customers with substantial economic benefits.
