The battery is not only applied to the energy storage power supply system of hydropower, thermal power, wind power and solar power station, but also widely applied to electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, military equipment, aerospace and other fields. With the continuous expansion of the application field of battery, the demand of its market is also increasing.

[0036] With the rapid development of battery technology, higher requirements are put forward for the safety and reliability of the battery. In the production process of the battery, the production equipment needs to be maintained frequently to ensure the production quality of the battery, and the safety of the operator in the maintenance process is also an important factor to be considered.
