Production process 8- baking
In the UPS (uninterruptible power supply) production process, baking is an important step after the battery unit packaging, the main purpose is to remove the water inside the battery, prevent battery short circuit and improve the safety of the battery. The following are the main steps and process requirements of the baking process:
main content
Preparation work
Before baking, it is necessary to clean the baking box, remove the dust and foreign matter in the box and baking clip, and prevent the dust from entering the inside of the battery cell during baking.
Trial run
Open the main baking power switch, and vacuum valve, compressed gas valve. After baking, enter the main operation interface, press manual operation to enter the manual operation interface; Display layer number and select button corresponding to each layer oven: heating, vacuum, nitrogen filling; Select vacuum, first test vacuum the oven, vacuum when the vacuum reaches -90KPA, then fill nitrogen, to check whether the equipment vacuum and nitrogen filling operation is normal.
Start heating
After baking confirmation, enter the manual operation interface; Activate the oven heating button to heat the oven.
Bake
Put the battery into the baking box for baking. There are two kinds of baking methods, contact baking and hot air circulation baking; Hot air circulation baking is to heat the gas through the heating unit, and then heat the battery through the circulation system.
Process inspection
During the baking process, the temperature and pressure in the baking box should be checked regularly to ensure that it is within the specified range.
Charge and discharge nitrogen
As needed, nitrogen is charged and vented during the baking process to maintain a dry environment and remove moisture.
Process record
The whole baking process is recorded in detail, including temperature, pressure, time and other data.
To complete heat treatment
When the heat treatment time is up, turn off the oven and stop heating. After the oven cools to a safe temperature, you can open the oven door and take out the heat treated lithium battery.
Cleaning and maintenance
After the heat treatment is completed, clean the oven and working area in time to ensure the normal use of the oven and extend the life.
CONCLUSION
The baking process is an important part of the battery manufacturing process, its purpose is mainly to ensure the stability of the battery performance, safety and extend the service life. By removing the water, impurities and gases inside the battery, as well as heat treating and curing the materials inside the battery, the performance and safety of the battery can be significantly improved. In practical applications, the parameters of vacuum baking need to be adjusted according to the specific battery type and specifications to ensure the quality and performance of the battery.
