The “AI Quality Inspection Revolution” on the PACK production line: How far is it from “post-production sampling inspection” to “real-time full inspection”?
In lithium battery PACK in the production process, welding quality is the key process that determines the consistency and safety of battery pack. Traditional production lines rely on manual visual inspection and offline sampling inspection, which not only has low efficiency, but also is difficult to find micron-level welding defects.
AI visual inspection system is changing this situation. In the welding process of energy storage PACK, CCD visual positioning and automatic welding technology can improve the consistency of key connection parts. More advanced solutions are equipped with OCT detection technology in welding and 3D + 2D visual detection technology after welding, combined with deep learning algorithm to realize comprehensive and accurate detection of complex welding quality. The whole line beat of some production lines has reached 43 seconds/PACK, covering the seven key processes of fuzzy grasping, film sticking into the box, screw gasket for twisting, blocking Press fitting, electrical testing docking, leakage test and upper cover tightening.
The core value of these technologies is not to "show off skills", but to change quality control from "after-the-fact discovery" to "real-time blocking". A virtual welding spot may not expose problems during factory inspection, but it may evolve into increased internal resistance, local overheating or even thermal runaway after half a year of use by the customer. AI visual inspection can identify anomalies and automatically distribute NG products at the moment of welding, reducing the outflow rate of defective products from the source.
Dongguan Juneng New Energy Technology Co., Ltd. is equipped with full-automatic laser welding equipment and AI visual inspection system in the manufacturing base, covering cell feeding, cell scanning code, gluing inspection, welding quality inspection and other key processes, upload all process data to the MES system for tracing the entire process. The incoming inspection process performs full inspection and capacity separation for cell and capacity deviation control.Within 1%.
For equipment manufacturers, when evaluating the manufacturing capability of PACK factory, a question worthy of attention is: Is your welding quality inspection random inspection or full inspection? Can the test data be traced back to each cell? Suppliers who can answer this question are usually more trustworthy than those who only say "we have automated production lines.
