Technical parameters：  

Application case

Experiment preparation

Material preparation: Prepare a certain number of standard size positive and negative slurry coating foil to ensure uniform coating and no impurities.

Tool preparation: In addition to the cutting and folding machine, you also need to prepare the early production equipment such as the coating machine and drying furnace, and the subsequent winding machine and liquid injection machine.

Environmental preparation: Ensure that the temperature and humidity conditions in the production workshop meet the process requirements to avoid the impact of dust and other pollutants.

Experimental procedure

Electrode coating and drying: First, use the coating machine to evenly apply the positive and negative electrode slurry on the aluminum foil or copper foil, and then send it to the drying furnace to remove the solvent and form a dry electrode sheet.

Pretreatment of the pole sheet: cut the dried pole sheet into an appropriate size for subsequent processing.

Pole slice cutting and laminating:

The pre-treated pole slices are put into the cutting and folding machine, and the position is automatically calibrated by the visual recognition system on the device.

Start the cutting program, according to the set size parameters, using precision tools to quickly and accurately complete the cutting operation of the pole piece.

Then, the device automatically switches to the laminated mode, and the cut pole sheet is stacked neatly by the manipulator in accordance with the predetermined number of layers and sequence to form the required cell structure.

Quality inspection: After each batch of cutting and lamination, random samples are selected for appearance inspection and size measurement to ensure that the edges of all pole pieces are neat and the interlayer alignment is good.

Cell assembly: the qualified pole sheet group is sent into the winding machine, and the diaphragm is rolled together to make a cylindrical cell, and the subsequent packaging, liquid injection and other processes.

Result analysis

Through the introduction of the cutting and folding machine, the company achieved the following improvements in the production process of the 18650 cylindrical lithium battery:

Improve production efficiency: The highly automated cutting and folding machine greatly reduces the processing time of pole slices and improves the speed of the overall production line.

Enhanced product consistency: The high precision and stability of the equipment ensure the quality of each pole piece and reduce differences caused by human factors.

Reduced production costs: Compared to traditional manual operations, automated equipment reduces the need for manpower, while reducing the rate of scrap due to incorrect operation.
