clear and distinct! Application of 355nm UV Laser in Electric Toothbrush Marking

In recent years, Chinese people have gradually paid more attention to oral health, and the oral health consumer market has become increasingly broad. Among them, in the field of oral cleaning, the shipment of electric toothbrushes has increased year by year. More than 300 brands of electric toothbrushes.

However, behind the many electric toothbrush brands, in fact, the price of the products varies greatly, and the quality varies. In order to further highlight the brand value and improve the anti-counterfeiting function of the product, the surface of the electric toothbrush case can be marked with a QR code and information such as brand logo, model, model, specification, etc., so that it has the meaning of anti-counterfeiting, traceability, marketing, and anti-tampering. The implementation cost is low, the promotion is easy, and the identification is easy.

The method of pasting the QR code label is obviously not suitable for the use environment such as electric toothbrushes that need to be repeatedly contacted with water, and the method of ink spraying will gradually become blurred over time. Only laser marking can achieve permanent marking, which is irreversible and irreversible, effectively avoiding the possibility of marking being tampered with, and the marking is clear and beautiful.

The shell of the electric toothbrush is mainly made of plastic. The RFH 355 nm UV nanosecond laser has the advantages of short wavelength characteristics and high material absorption rate, which can realize "cold" processing of plastic materials, and the pulse width of <25ns is often too late for heat. The transfer to the outer area of ​​the mark stops, and the heat affected zone is very small when marking, the surface will not be scorched or carbonized, and the grade of the mark will be improved. And its high beam quality (M2<1.2), coupled with the easy focusing characteristics of 355nm ultraviolet light, the diameter of the spot after focusing is very small, reaching the micron level, and the peak power is high, which can instantly vaporize the plastic surface material, thereby leaving a mark, In addition, the marked lines are more delicate, the edges are smooth, and the high-quality two-dimensional code or one-dimensional code is easier to be recognized by the scanning device.

Considering that the electric toothbrush head has a certain service life, it is often necessary to replace the toothbrush head regularly after a period of use to ensure the oral cleaning effect. At this time, the 355nm ultraviolet nanosecond laser can also be used to mark the matching model and other information in the downloaded area of ​​the toothbrush head. The effect is outstanding, and the efficient use of laser marking on the electric toothbrush production line can be realized.
