Traditional metal cutting mold has long been adopted for battery electrode plate cutting of NEV. After being used for a long time, the cutter may wear, resulting in unstable process and poor cutting quality of the electrode plates. Picosecond laser cutting solves this problem, which not only improves product quality and working efficiency but also reduces comprehensive costs. Equipped with S&A ultrafast laser chiller that can keep long-term stable operation.
The fast-growing laser technology has infiltrated into all walks of life. With multiple advantages over the traditional process, the technology has brought efficient work and premium products for processing industry.
Traditional metal cutting mold has long been adopted for battery electrode plate cutting of new energy vehicles. Since metal mold punching needs to adjust the cutter according to electrode plate’s property and thickness, each cutting process takes a lot of time to test and adjust, resulting in the decreased efficiency. After being used for a long time, the cutter may wear, resulting in unstable process and poor cutting quality of the electrode plates.
At the early beginning, people also tried adopting picosecond cutting. But for the heat-affected zone and burr are relatively large after picosecond laser processing, it can not meet with the needs of battery manufacturers.
Picosecond laser technology solves the problem of electrode plate cutting
Due to the extremely narrow pulse width, picosecond laser can vaporize materials relying on its ultrahigh peak power. Different from nanosecond laser thermal processing, picosecond laser belongs to gasification ablation gas processing, without producing melt beads, and the processing edge is neat, which properly solves various pain points in the cutting of new energy battery pole pieces.
Advantages of picosecond laser cutting
1. Improve product quality and working efficiency
Based on the principle of mechanical occlusion, metal die-cutting is prone to defects and requires repeated debugging. The long-term work may result in wear and depressed rate of conforming product. It needs to replace the cutter and halt production for 2-3 days, so the work efficiency is low. However, picosecond laser cutting can stably work for a long time. Even if the material is thickened, there will be no equipment loss. For the thickened materials, you only need to improve 1-2 optical path system, which is very convenient and does not need to stop production, helping to improve efficiency.
2. Reduce comprehensive cost
The purchase cost of the picosecond laser is relatively high, but after long-term operation, the cost of using picosecond laser will be much lower than that of traditional metal cutting dies in terms of machine maintenance, production time and product quality.
The long-term stable operation of picosecond laser needs support from S&A ultrafast laser chiller
For a stable optical output, high production efficiency and reduced cost of your picosecond laser, you need to configure it with an ultrafast laser chiller. With temperature control precision up to ±0.1℃, S&A chillers can stabilize the optical output of the picosecond laser and optimize the cutting quality. Featured with easy operation, S&A ultrafast laser chiller comes with multiple settings and fault display functions. Alarm protection functions such as compressor delay protection, compressor over-current protection, flow rate alarm, ultrahigh and ultralow temperature alarms to further protect the laser device and water chiller. Multi-country power specification available. In compliance with ISO9001、CE、RoHS、REACH international standards. S&A laser chiller is a wonderful choice for cooling your laser equipment!
