technical parameters：

Electric source	Single-phase AC220V±10%, frequency 50Hz, power 0.3KW
Air source	0.5-0.8MPa compressed air or high-pressure cylinders (high-pressure cylinders are normally used after 1.3-1.5MPa depressurized) Pay attention to; 1. The normal steel shell wall thickness is less than 0.4mm, and the air pressure is 0.5-0.8MPa. In special cases, the wall thickness is greater than 0.4mm, and the material is relatively hard, 0.8-1.2MPa air source is optional. 2. Different steel shell air pressure Settings are different, the pressure will not roll when the pressure is small, and the pressure will roll out when the pressure is large (the pressure has been adjusted before the factory can meet 95% of the steel shell, and then adjust the pressure in special circumstances)

Application case：

Experiment preparation

Material preparation: Prepare an appropriate amount of assembled cylindrical lithium battery semi-finished products, including the battery that has completed the assembly of positive and negative electrode pieces, electrolyte injection and initial packaging.

Tools: In addition to the cylindrical battery roller, prepare auxiliary tools such as gloves, scissors, and ruler.

Environment preparation: Ensure that the operation area is clean and dust-free, and that the temperature and humidity meet the technical requirements to avoid the impact of static electricity and dust.

Experimental procedure

Battery pretreatment:

The assembled cylindrical lithium battery semi-finished product is placed on the operating table to check whether there is leakage or other defects.

Confirm the initial packaging effect of the battery, and ensure that the aluminum shell fits well with the internal components of the battery, without bubbles and leaky sealing.

Parameter setting:

According to battery specifications and groove requirements, set the groove parameters of cylindrical battery rolling machine, including groove depth, groove speed and groove pressure.

It can be tested in small batches first and adjusted to the best state before being formally put into production.

Battery loading:

Place the battery on the work table of the cylindrical battery rolling machine to ensure the correct and stable position of the battery.

Adjust the fixture so that the battery is held in place to avoid moving during the rolling groove.

Rolling groove operation:

Start the rolling slot program, and the rolling slot device will automatically roll the battery housing.

Ensure that the depth and shape of the rolling groove meet the requirements, and the rolling groove line is continuous, smooth, and without burrs.

After the rolling groove is completed, the rolling groove device automatically returns and the battery is removed from the workbench.

Quality inspection:

Carefully check the cylindrical lithium battery after each rolling groove to ensure that the rolling groove line has no burr, no crack, no deformation.

Use tools such as microscopes and thickness gauges for detailed inspection and record relevant data.

Performance test:

Some samples were randomly selected for charge-discharge cycle test to evaluate the key indicators such as capacity retention rate and internal resistance.

Record the test results and analyze the effect of the rolling groove on the battery performance.

Result analysis

Through the use of cylindrical battery rolling machine, the company has achieved the following results in the rolling process of cylindrical lithium batteries:

Improve the quality of the rolling groove: The high-precision rolling groove system ensures that the depth and shape of the rolling groove are consistent, reducing burrs and cracks, and improving the fixing and sealing of the internal components of the battery.

Enhanced safety: The high-quality rolling groove reduces the safety risks of the battery in the charge and discharge process, and improves the safety of the battery.

Improve production efficiency: The automated all-in-one design significantly shortens the rolling slot time, improves production efficiency and reduces labor costs.

Reduce the rate of defective products: standardized operation process and high-precision equipment reduce the error caused by human operation and reduce the rate of defective products.
