The principle of fiber cleaning machine

The principle of fiber cleaning machine mainly varies depending on the cleaning technology used. Here are several common principles of fiber cleaning machines:

1、 High pressure airflow or high-pressure water flow cleaning

This is the most basic and common cleaning method for fiber cleaning machines. Its working principle is to spray high-pressure air or water onto the surface of the optical fiber through a nozzle, and use impact and friction to remove dirt and impurities from the surface of the optical fiber. This method is simple and direct, and can effectively clean most of the dirt on the surface of the optical fiber.

2、 Ultrasonic cleaning

Ultrasonic cleaning machines have been widely used in fiber laser cleaning. The principle is to use the sound wave energy generated by ultrasonic vibration to transmit to the cleaning solution in a high-frequency transformation mode with tens of thousands of compressions and depressurizations per second. This high-frequency vibration can cause microbubbles in the cleaning solution to rapidly expand and close, generating strong shock waves and microjets, thereby removing dirt from the surface of the optical fiber. Ultrasonic cleaning has the advantages of high efficiency, precision, and no damage, especially suitable for cleaning hard to reach parts such as fine seams and micropores in fiber lasers.

3、 Laser cleaning

The nanosecond fiber laser cleaning machine utilizes the principle of thermal expansion and contraction generated by laser irradiation on the surface of the substrate to strip, crush or vaporize surface contaminants, thereby achieving the cleaning effect. This method has the advantages of no chemical reagents, no media, no water, easy installation, operation, and automation. Meanwhile, laser cleaning can precisely control the cleaning area and depth, causing minimal damage to the surface of the optical fiber.

4、 Liquid+gas cleaning

Some high-end fiber cleaning machines, such as the Offsoon Pro fiber end face cleaning machine, use a liquid+gas cleaning principle. The cleaning solution can quickly dissolve the stains on the fiber end face, and then the dust-free gas sprayed will blow away the cleaning solution together with the oil stains. This approach combines the advantages of liquid and gas, enabling more efficient cleaning of fiber end faces while protecting them from damage.

In summary, there are various principles of fiber cleaning machines, and the choice of which principle depends on specific cleaning needs and factors such as the material and shape of the fiber optic. In practical applications, appropriate cleaning methods and equipment should be selected according to specific situations.
