800W Ultrasonic Welder for Solid Cell Production

Ⅰ、Introduction

This 800W ultrasonic welding machine for solid cell tab welding. It can be used in glove box. For welding pure aluminum strip 0.10mm + pure aluminum foil 0.012-0.018mm (within 20 layers). For welding pure nickel strip 0.10mm + copper foil 0.012-0.018mm (within 20 layers).

Ⅱ、Equipment size
1. Size of the spot welder high power generator ( LxWxH ): 550mm x300mm x550mm

2. Size of the spot welder head (topmost: LxWxH): 480mm x200mm x380mm

3. All measuring instruments on the equipment use metric units

Ⅲ、Working principle

Mainly composed of ultrasonic generators, transducers, molds, pneumatic components, racks, etc. The working principle is that the transducer converts the ultrasonic frequency high-power oscillation signal into corresponding frequency mechanical energy, which is applied to the interface of the metal sheet to be welded, causing instantaneous heat generation at the junction of the metal sheet, and then activating the particles in the metal lattice, causing the molecules at the junction of the metal sheet to penetrate each other and fuse together.

Ⅳ、Function

*This product is used for welding between aluminum foil and aluminum tabs, and between copper foil and copper plated nickel or nickel tabs

*The tab welding method is horizontal, and the welding surface life is ≥ 100000 times;

*Welding head standard, made of imported powder alloy, with a welding point height of 0-50mm, with straight or beige patterns on the upper welding head and mesh patterns on the lower mold. The height between the welding surface and the welding head is adjustable from 0 to 50mm, and there are 4 welding surfaces available for the welding head.

*The transducer can withstand a power of 800 watts

*The built-in frequency of the ultrasonic generator is adjustable, the switching power supply is constant voltage and current (constant amplitude), and the amplitude is stepless adjustable;
