The Technology of the Industry丨Lyric Ultrasonic Welding Equipment Constructs the Ultimate Solution for "High-Precision Welding"!

In power battery tab welding, a mere 0.1mm deviation can cause a sharp decline in cell performance; in 120-layer copper foil welding, just 0.1% energy fluctuation may trigger over-welding risks. In the Industry 4.0 era, precision is the lifeline.

Lyric Ultrasonic Welding Technology delivers the ultimate " High-Precision Welding " solution for new energy, semiconductor and automotive manufacturing industries, with its three core advantages: micron-level precision control, AI-powered intelligent monitoring and full-scenario adaptability.

The Lyric ultrasonic welding machine has achieved breakthroughs in multiple core technologies and realized stable and reliable welding spots.

The horizontal welding machine TL20B-6.2 features an original dual-rail frame. Under a high pressure of 3000N, the backward displacement of the welding head is less than or equal to 0.02mm, thus solving the precision problem in the industry. 

More Stable Frame: The triple-unit mounting node adopts dual-guide support to prevent welding head tilting. Under a welding pressure of 3000N, the tilting displacement of the welding head is ≤0.02mm.

Higher Positioning Accuracy: The unique pneumatic circuit design optimizes the position control accuracy of cylinder drive, achieving a positioning accuracy of 0.01mm.

Faster Speed:

The addition of a buffer device to the vertical movement mechanism allows the triple-unit system to operate at higher speeds while ensuring welding quality. Maximum single-station cycle rate: 20 PPM.

Longer Lifespan:

Equipped with a 4-sided welding head, the total service life exceeds 500,000 cycles.

Broader Applications:

By replacing the tooth profiles of the welding head and base, the system can adapt to various pre-welding and final-welding scenarios for battery cell tabs.

The high-speed welder HSP20B-6.2 achieves 1-second faster per weld cycle, with single-station throughput reaching 20 PPM (parts per minute) – delivering 30% productivity boost.

Key Features: Combines the flexibility of pneumatic actuation with the rigidity of servo drive, enhancing speed while preventing foil cracking caused by rigid impact.

Applications: Welding of tabs for prismatic aluminum-shell battery cells, welding of tabs for pouch battery cells, welding of tabs for blade battery cells, welding of tabs for solid-state batteries, terminal welding for wire harnesses.

Single welding operation is 1 second faster than conventional welders.

The direct-pressure welder VS20B-6.2 shatters industry limits with 8,000W peak power, achieving single-pass penetration on 120-layer copper foils (62mm×12mm weld area) while maintaining multi-material compatibility (copper/aluminum foils). This revolutionizes the conventional two-pass approach for large weld areas!

Capable of welding 120 layers of 36×10mm + 3mm nickel-plated copper TABs at 8,150W power, delivering excellent weld quality.

Features a 62×12mm weld imprint design with uniform amplitude distribution validated by simulation analysis.

Features: It adopts a two-point support full-wavelength welding head design, which enables one-time welding for materials with a size of 62mm x 12mm and 120 layers of copper foil.

Large area: The area of the welding region is 62mm x 12mm.

High power: The power can reach up to 8000W.

One-time welding: It can be formed by welding once, without the need for a second welding.

Lyric’s 3rd-Gen Ultrasonic Welder integrates adaptive voltage & air pressure technology for stable output, structural optimization for rapid response and enhanced efficiency, and multi-layer safety protection for operational reliability. Powered by AI-driven algorithms, it enables real-time weld quality monitoring and intelligent process optimization.

Enhanced Stability: Voltage Adaptive Control + PFC ensures consistent output power unaffected by grid fluctuations. Pressure Adaptive System + Constant Amplitude Technology maintains stable amplitude output across varying pressure conditions.

• Higher Speed: Proprietary frame structure, buffering system, and pneumatic circuit design drastically improve response time. Achieves <3-second welding cycles, significantly boosting production efficiency.

• Enhanced Safety: It supports the dual-control mode of welding depth and welding energy, effectively preventing incomplete welding and over-welding. It also has functions such as real-time monitoring of the collapse ratio, anti-empty welding, anti-hand-pressing, trigger position monitoring, automatic tracking of anti-temperature drift frequency and anti-wrinkle, ensuring the safety of operations.

• Advanced Intelligence: Based on AI model inference technology, it realizes the real-time monitoring of welding quality and the analysis of production process capabilities, comprehensively improving the intelligent level of the equipment and the controllability of the process.
