The UV laser engraves the graphics and text on the surface of the lithium battery without damaging the battery

Lithium battery manufacturer customers buy 10 355nm UV lasers at one time

Lithium cell is a type of battery that uses lithium metal or lithium alloy as the positive/negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream.

Lithium batteries are widely used in a series of electronic devices such as mobile phones and digital cameras, and their surface needs to be engraved with clearly visible information and text. The RFH 355 ultraviolet laser, jointly created by professors at home and abroad, can engrave the required characters and patterns on the surface of the lithium battery during marking, but it will not damage the important performance of the lithium battery itself. And in the process of using the lithium battery, it may be aging, or it may be easy to generate heat, but it will not make the words and patterns on these markings distorted or blurred in the slightest.

Recently, Mr. Li, a lithium battery manufacturer, purchased 10 RFH 355nm ultraviolet lasers specifically for marking the surface of lithium batteries. Mr. Li said that the ink jet coding method has been used before, but it is easy to cause uneven ink marks, not beautiful enough, deformation of the inner surface, easy to be altered, not environmentally friendly, and frequent replacement of consumables is required. Therefore, it is now fully switched to UV laser marking mode.

Ultraviolet laser marking is to use the laser thermal effect to ablate the surface material of the object, thereby leaving a permanent mark. It has the advantages of non-contact marking, low cost, no consumables, good permanence, no deformation, no pollution, high speed, high stability, and high precision engraving.

The power range of S9 series pulsed ultraviolet solid-state lasers developed and produced by RFH is 3W-10W. The focused spot is extremely small, and the processing heat-affected zone is small, and there is almost no damage caused by heat, so it is called a cold light source. Because of the small heat-affected area of ​​the UV laser, there is no thermal effect, which avoids deformation or scorching when processing plastics.

"Small size", "±0.002mm high precision", "high power stability", and "high cost performance" are the core advantages of RFH S9 UV lasers.

Compared with products of the same type, S9 series lasers are smaller in size, exquisitely designed, and more stable in light output. The compact design is not only simple to save space and convenient to move, it can also prevent users from making large optical paths, which greatly reduces production and processing costs.

The new S9 has excellent quality and strong competitiveness. The laser has a wavelength of 354.7nm and a wide range of repetition frequency (single pulse to 200kHz), which can be better absorbed by the material and is less destructive to the material. The superior beam quality (M2<1.2) can be strictly guaranteed in all frequency ranges; the pulse width is <20ns@30k, and the heat-affected area during processing is extremely small.

The S9 series also adopts unique Q-adjusting control technology, and uses fully digital intelligent power supply to control the operation. It is easy to operate and comes with an internal cavity self-purification system, which has a longer life, more stable operation and low maintenance cost.

The powerful after-sales guarantee system guarantees your continuous high-quality production. This series can be widely used in electronic product marking, electrical appliance shell marking, consumer electronics micro-processing and other fields.
