Develop an intelligent recognition system to automatically identify material types and adjust laser parameters, achieving automation and intelligence in the cutting process.

4、 Control of heat affected zone during cutting process

The heat affected zone generated during laser cutting may have adverse effects on the performance of the battery case, such as causing material performance degradation, cracking, etc. Therefore, how to effectively control the heat affected zone is a key issue that needs to be addressed in the application of laser cutting machines.

Breakthrough in technical difficulties:

Adopting advanced cooling technology and thermal management strategies to effectively reduce heat accumulation during the cutting process.

Optimize laser cutting process parameters, such as reducing laser power, increasing cutting speed, etc., to reduce the range of heat affected zone.

5、 Improvement of stability and reliability of cutting equipment

The processing of new energy battery shells has extremely high requirements for the stability and reliability of equipment. As one of the key equipment, the stability and reliability of laser cutting machine directly affect the processing quality and production efficiency of battery cases.

Breakthrough in technical difficulties:

Strengthen equipment maintenance, regularly check the operation status of equipment, and ensure that the equipment is in the best working condition.

Adopting redundant design and fault warning system to improve equipment reliability and fault response capability.

In summary, laser cutting machines face many technical difficulties in the processing of new energy battery shells. However, by adopting high-precision laser cutting systems, developing efficient cutting processes, establishing material database systems, optimizing cutting process parameters, and strengthening equipment maintenance measures, we can effectively overcome these technical difficulties and provide more efficient, accurate, and reliable solutions for the processing of new energy battery cases.
