- X-ray 24 ppm
- X-ray accuracy 60 μm
Shunyuan Laser welding machines
Subsidiary Shunyuan Laser, founded in 2015, builds laser welding, cutting, marking and cleaning systems for batteries, photovoltaics and automotive parts. The EV battery seal pin welder reaches 150 mm/s, top cover sealing welding 250 mm/s, and the precise laser welder repeats to ±0.02 mm.
- Seal pin welding 150 mm/s
- Top cover welding 250 mm/s
- Repeatability ±0.02 mm
- Laser cleaning and cutting
Selecting a Lyric Robot line by cell type
A line is chosen by cell format and production stage.
For prismatic cells there is an assembly line with 124 workstations and 8 kW laser welding; for cylindrical cells a line from 300 ppm for cells 40–46 mm in diameter and 70–170 mm long; for pouch cells winding machines at 3000 mm/s line speed and cutting and stacking machines with ±0.15 mm accuracy.
The chain is completed by formation and capacity grading machines (20 ppm), X-ray stack inspection and Module & Pack lines with 85–95 % automation on the module line. The manufacturer also runs module line projects for overseas customers in the USA and Poland.
Other Lyric Robot product lines
Besides battery lines, Lyric Robot builds three-in-one e-motor assembly lines, fuel cell stack assembly lines with ±0.1 mm stacking accuracy and photovoltaic equipment, including PERC laser grooving equipment.
Laser welding, cutting, marking and cleaning come from subsidiary Shunyuan Laser; formation, grading, OCV and DCIR equipment from subsidiary Shunshi.
