Product Description Battery Pouch Cell Electrode Production Assembly Line Lamination Stacking MachineDevice function:Battery Pouch Cell Electrode Production Assembly Line Lamination Stacking Machine is mainly used for zigzag lamination of square lithium-ion power battery cells.Refer Picture For Lithium Electric Z Shape Laminating Machine:Workflow:The diaphragm is automatically unwound, and introduced into the lamination table through the roller with constant tension. The lamination table drives the diaphragm to move back and forth. The suction cups take out the positive and negative plates from the feed tank respectively. After CCD positioning correction, they are placed on the lamination table.Once it achieves a pre-set number of layers, the diaphragm is thermally cut off (leaving a small amount of tailings). And then the cells are transferred to the gluing mechanism by the manipulator; After that, the glued cells will be transferred to the stacking platform by the manipulator.The process flow chart is as follows:Equipment features:1.Diaphragm: active unwinding; tension control; diaphragm positioning correction; diaphragm de-static; diaphragm alignment accuracy from sides: ±0.3mm (head and tail alignment ±0.5mm);2.High precision: Through precise positioning process for the pole pieces, the overall lamination accuracy for each piece is guaranteed to reach ±0.3mm (alignment accuracy for adjacent pole pieces: ±0.2mm);Alignment accuracy between pole piece and diaphragm: center deviation ±0.2mm.3.High efficiency: lamination speed can reach 0.5-0.6s/piece (for double station, excluding auxiliary time 13s);4.Anti-dust protection: an anti-dust protection mechanism is installed in the material box and at a pre-positioning location;5.Reliability: The equipment module is fixed with positioning pins;6.Excess-cell/ Less-cell Fool-proof Mechanism:once an emergency situation with excess-cell/ less-cell loading happens, the system will accurately detect and alarm through the ultrasonic sensor meanwhile activate the emergency stop function automatically, which can effectively prevent more than required cells from being stacked into the battery.7.Incoming pole pieces detection: The four corners of the pole piece and the pole lugs are detected by CCD to identify missing/folded corners.When any NG pole piece is identified, the system will automatically alarm and stop.;8.The material box for pole pieces, the lamination table and the suction piece are all equipped with dust removal devices, and all dust is centrally treated;Equipment parameters:ItemSpecificationDimensionsL3200 x W1700 x H2000mm (dimensions are for your reference only, subject to specific design)Weight/LoadAbout 4000KG;
