cylindrical battery sealing machine

CY-510B cylindrical battery sealing machine is driven by hydraulic jack to realize the packaging process of cylindrical battery. The standard configuration mold can be used to seal 18650 batteries. After replacing the mold, it can seal φ10mm-φ50mm, L20mm-L140mm cylindrical batteries (such as 4680, etc.).

Product characteristics:

1. The manual hydraulic cylinder drives the mold to seal the cylinder battery, and the operation of the strengthening handle saves labor;

2. Small and light, it can be easily used in the glove box controlled by water and oxygen through the transition bin;

3. Precision mold design ensures accurate and reliable sealing molding, excellent sealing quality and long service life;

4. Selection of different molds can package different specifications of cylindrical batteries, to achieve a multi-purpose machine;

5. Good sealing, can pass professional testing;

6. Pure manual operation, no electricity and gas, easy to use.

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 sealer, prepare auxiliary tools such as gloves, scissors, and rulers.

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. The operating area should be equipped with an inert gas (such as argon) protection system to prevent the battery from reacting with air contact.

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 the battery specifications and sealing requirements, set the sealing parameters of the cylinder battery sealing machine, including sealing temperature, sealing time and sealing 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 workbench of the cylindrical battery sealer to ensure the correct and stable position of the battery.

Adjust the fixture to keep the battery in place and avoid moving during the sealing process.

Sealing operation:

Start the sealing procedure, and the sealing device will automatically seal the opening of the battery.

Ensure that the sealing line is continuous, smooth and free of bubbles. When the sealing is complete, the sealing device automatically returns.

Check the sealed battery to ensure that the sealing line is not leaky or burnt.

Quality inspection:

Carefully check each piece of sealed cylindrical lithium battery to ensure that the sealing line has no leakage seal, no bubbles, no burning and other undesirable phenomena.

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 sealing on battery performance.

Result analysis

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

Improve the sealing quality: The high-precision sealing system ensures the continuity and flatness of the sealing line, reduces the leakage sealing and bubble phenomenon, and improves the sealing and consistency of the battery.

Enhanced safety: The high quality seal 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 sealing 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.
