    Product Details

    　　1. Equipment introduction


    　　The equipment disassembles the battery cells after the OCV test is completed, and after entering the encapsulating machine, they undergo code scanning/weighing/thickness measurement/covering/folding/sticking of insulation meson/appearance inspection/automatic blanking.
