pneumatic button battery sealing machine

CY-PN110-S pneumatic button battery sealer adopts cylinder drive to realize the encapsulation and dismantling process of button batteries. Standard configuration sealing die can be used for CR2016, CR2025, CR2032 and other diameter of 20mm series button battery sealing, after replacing the mold accessories can be used for other diameter button battery (such as CR2450, CR1620, etc.) to seal. Optional disassembly mold is used to completely disassemble the positive and negative battery shell after sealing the button battery, which is convenient to study and analyze the sample intake of the internal materials of the battery.

Product characteristics：

1. The cylinder drives the mold to seal the button battery, and the sealing pressure is controlled by manual valve;

2. Compact and light, can be easily placed in the glove box;

3. Compressed air or inert cylinder two ways of gas supply, compressed gas exhaust external connection can prevent damage to the glove box atmosphere;

4. Precision mold design ensures accurate and reliable sealing molding and excellent sealing quality;

5. Different molds can be configured to package and disassemble button batteries of different specifications, so as to achieve a multi-purpose machine;

6. Pure pneumatic operation, no electricity, easy to use;

Technical parameters：

Application case：

Experiment preparation：

Material preparation: Prepare an appropriate amount of positive material (such as manganese dioxide), negative material (such as lithium metal), diaphragm, electrolyte, positive and negative shell, etc.

Tools: In addition to the pneumatic button battery sealer, you also need to prepare gloves, scissors, rulers and other auxiliary tools.

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 operation area should be equipped with a ventilation system to prevent the accumulation of harmful gases.

Experimental procedure

Sealing operation

Material preparation:

Use an electronic scale to accurately weigh the required positive material, negative material and electrolyte.

The positive material and the negative material are placed in the positive and negative shell respectively.

Cut diaphragm to desired size and set aside.

Electrolyte injection:

Use a dropper or microinjector to inject an appropriate amount of electrolyte into the positive shell to ensure an even distribution of electrolyte.

Pay attention to control the amount of electrolyte injection to avoid too much or too little.

Assembly operation:

Place the cut diaphragm on the electrolyte of the positive shell to ensure that the diaphragm is flat and free of bubbles.

Place the negative housing over the positive housing, making sure the two are aligned.

Sealing operation:

Place the assembled battery on the workbench of the pneumatic button 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.

Set sealing parameters, including sealing pressure, sealing time, and sealing temperature. According to the battery specifications and sealing requirements, small batch tests can be carried out first and adjusted to the best state before being formally put into production.

Start the sealing procedure, and the pneumatic system will automatically seal the battery. Ensure that the positive and negative shells of the battery are tightly combined during the sealing process, and there is no leakage.

After the sealing is complete, the pneumatic system automatically returns and the battery is removed from the workbench.

Quality inspection:

Carefully check each piece of sealed button lithium battery to ensure that the positive and negative shells are tightly combined, no leakage, no bubbles, no cracks.

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 pneumatic button battery sealing machine, the company achieved the following results in the sealing process of button lithium batteries:

Improve the sealing quality: the high-precision pneumatic system and stable sealing device ensure that the positive and negative shell of the battery is tightly combined, reducing leakage and bubble phenomenon, and improving the sealing and consistency of the battery.

Enhanced consistency: Standardized operating processes and high-precision equipment ensure that the sealing effect of each battery is highly consistent, improving the consistency and stability 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.
