MES system features for the Lion cell quality control
1. Process automatically control product quality:
in the process of the testing process, or operation station, according to the parameters set by the system, it can inspect the product in the production and judge the product is normal or abnormal automatically , if in the process of coating , the β/X ray can inspect the coating thickness then make the feedback to the controller system to realize closed-loop control to ensure the consistency of the coating thickness , the appearance of the CCD inspection pole piece and select out the NG appearance pole piece, X-Ray facilities autofilter the NG lamination cover, Hi-Pot and low insulation test inspect and autofilter NG products, CCD inspects the core pole ear folding welding and assembling packaging effect, automatic injection line by weighing the automatic scan code to ensure injection fluid volume, in the batteries aging and formation procedure，it can be according to the curve data to determine the quality of the product, the OCV test automatic screening of K value (self-discharge) bad product, etc.
2. Automatic assembly can be realized for the cells matching : in order to reduce the influence of "barrel effect" on the electrical performance of the battery group by combining the cell capacity, OCV, ACIR, DCIR and other information in the manufacturing process, the data range of each parameter is set by the system, and the battery is automatically grouped by the bar code or two-dimensional code on the surface of the cell aluminum plastic film. After grouping the cells, according to the requirements of the number of series-parallel cells in the battery pack, the system "packs" and produces the barcode of the battery pack, so as to realize the automatic grade-by-level link and traceability of "the battery cell -- the battery pack".
