AI Technical Summary
Existing lithium battery cap welding devices have difficulty clamping lithium batteries of different sizes, resulting in poor welding stability. Furthermore, gaps may occur when clamping larger batteries, affecting the welding effect.
The design incorporates a combination of base, support column, top plate, disc, sleeve, electric telescopic rod, arc bar, support rod, electric telescopic column, cross bar, pressure welding ring, and drive components. Through the coordinated operation of multiple sets of electric telescopic rods and drive components, it achieves stable clamping of lithium batteries and caps of different sizes. Furthermore, the L-shaped rod and pressure block press the center of the cap before welding, improving welding stability.
It improves the versatility and stability of pressure welding, enhances welding efficiency and quality, adapts to lithium batteries and caps of different sizes, and ensures the stability and safety of the welding process.
