五大技术亮点介绍

Five technical highlights are introduced

01

行业先进复合切割腔体成型技术，破除“背板切粉尘堆积”、“悬空切高极耳抖动”顽疾

The industry's advanced composite cutting cavity forming technology eliminates the stubborn problems of "backboard cutting dust accumulation" and "suspended cutting high pole ear jitter"

行业内普遍使用的背板切技术和悬空切技术，切割极片时产生的熔珠、粉尘易堆积在背板上，长此以往易造成极片破损，影响良品率；悬空切针对高极耳、薄基材，抖动较大，容易造成激光离焦，出现连带现象，影响机器稼动率。利元亨创新式复合切割腔体成型技术，可兼容无废料边、叠片小间距极耳切割，节约来料成本；在粉尘抑制上，切割区域可达万级洁净标准，设备连续稳定运行72H，腔体无明显粉尘堆积；在极耳抖动抑制上，切割极耳高度≥55mm，60m/min运行时，极片抖动≤±0.3mm，极耳抖动小，除尘效率高。破除“背板切粉尘堆积” 、“和悬空切高极耳抖动”顽疾。

The back plate cutting technology and the suspended cutting technology commonly used in the industry, the molten beads and dust generated when cutting the electrode are easy to accumulate on the back plate, which will easily cause the electrode to be damaged in the long run, affecting the yield rate; the suspended cutting technology is aimed at high pole ears and thin substrates , The jitter is large, which is easy to cause the laser to defocus, and the associated phenomenon occurs, which affects the machine utilization rate. Lyric Robot's innovative composite cutting cavity forming technology is compatible with scrap-free edge, lamination and small-pitch tab cutting, saving the cost of incoming materials; in terms of dust suppression, the cutting area can reach the 10,000-level cleanliness standard, and the equipment runs continuously and stably for 72H , there is no obvious dust accumulation in the cavity; in terms of pole ear jitter suppression, the cutting pole ear height is greater than or equal to 55mm, and when running at 60m/min, the electrodejitter is less than or equal to ±0.3mm, the pole ear jitter is small, and the dust removal efficiency is high. Eliminate the stubborn ailments of "dust accumulation on the back panel cutting" and "jittering with the pole ear of the high-hanging cutting".
