AI Technical Summary
Existing soft-pack lithium battery liquid injection and packaging equipment suffers from low positioning accuracy, poor adaptability, low automation, unstable packaging quality, poor sealing, and lack of state detection and feedback mechanisms, resulting in poor battery consistency and safety.
The sealed shell structure is guided by a slide rail. Combined with a motor adjustment component, pressure switch and sensor, it can achieve precise adjustment and automatic control of the positioning seat spacing. The liquid injection is triggered by the cooperation of the stop block and pressure switch. The electric push rod and heating plate ensure the sealing quality. It is equipped with a sealing plate and sealing strip to improve the sealing performance. The status of the soft package is monitored in real time to avoid empty injection and volume difference.
It achieves precise positioning, strong adaptability, high degree of automation, stable packaging quality, and good sealing performance, reducing labor costs and material waste, and improving battery consistency and safety.
