In the process of year-end after-sales visit to Wanwa users, Chuangxin staff found that some users had caused external pollution to the laser output head and cutting head due to improper operation methods when installing and replacing Wanwa laser output heads. If the cleaning is not carried out in time, the dust falls on the cutting head lens, causing the lens burning point and burn through, and in serious cases, causing the crystal burning point inside the ten thousand watt laser head.

It is hereby recommended that all users correctly install and clean the ten thousand watt LOE laser output head, and form the habit of timely cleaning, which will help extend the service life of the laser output head and improve the processing effect.

1 - Prepare cleaning tools

Proper cleaning and installation of the ten thousand watt laser output head can ensure long-term and efficient processing

2 - Take out the integrated LOE ten thousand watt output head

Generally, LOE products have three states:

1 - Separately packed LOE: open the packing box (Figure 1), take out the whole LOE from the box and place it in the inspection area;

2 - LOE installed on the whole machine: remove the front metal parts of LOE from the whole machine (Fig. 2) and place them in the inspection area;

3 - LOE installed on the cutting head: Remove the front metal part of the LOE from the cutting head (Fig. 3), place it in the inspection area, and directly follow step 3.

matters needing attention:

1 In the process of taking, it is necessary to protect the front-end metal parts and the back-end optical fiber, and it is not allowed to collide with the ground or other hard objects;

2 After the LOE is removed from the cutting head, the assembly surface of the cutting head shall be sealed and dust-proof as soon as possible, and the rubber ring shall not be loosened.

3 - Inspect the protective film of ten thousand watt output head

Rotate and remove the dust cap (Fig. 4). Visually inspect the outer surface of the green protective film. If dirt or foreign matters are found, clean it with a dust-free cloth dipped in alcohol. Slightly tear off the protective film (Fig. 5) and visually inspect the inner surface. If dirt is found, the protective film shall be scrapped. If no dirt is found, one side of the protective film shall be pasted on a clean table or other areas for standby (Fig. 6).

Note: When pasting the protective film, try to reduce the pasting area so that it can be reused later.

4 - Inspect the cleanliness of 10,000 watt LOE metal parts

Visually inspect the metal part surface at the port edge, the inner wall of the port, and the metal step surface at the crystal edge in sequence under the light. If the port edge is dirty, clean it with a dust-free cloth dipped in alcohol (Figure 7); If the inner wall of the port and the step surface are found to be dirty, according to the shape and location of the dirt, use a round or pointed cotton swab to clean it with alcohol (Figure 8 and Figure 9). If some foreign matters are found to be too small to be cleaned, they can be cleaned under a microscope or CCD.

matters needing attention:

1 The finger cover must be worn. In the cleaning process, if the finger cover, dust-free cloth and cotton swab are found dirty, they should be replaced in time;

2 The cotton swab shall be used with moderate force to avoid cotton yarn or debris due to friction.

5 - Inspect the cleanliness of 10000 watt LOE crystal

1 - Turn on the display and CCD switch, adjust the scale to "0.7" (Fig. 10), adjust the brightness of the LED light, and then fix the LOE in the tooling and lock it (Fig. 11). Adjust the CCD focal length to ensure that the entire crystal end face is clearly visible;

2 - Check the cleanliness of the entire crystal end face on the screen. If dust or foreign matters are found, use a round headed cotton swab dipped in alcohol for cleaning. When using the cotton swab, pay attention to wiping in a straight line in one direction (Fig. 12) with gentle force. Rotate the cotton swab 180 times each time and continue to wipe on the other side. After wiping twice, the cotton swab shall be scrapped. It is not allowed to circle or wipe back and forth to prevent dust particles from polluting other areas or directly scratching the surface of the cotton swab;

3 - After cleaning, confirm again under the CCD whether the dust or foreign matter has been completely removed, and no residual alcohol seal or other movable foreign matter is allowed.

Note: If there is no CCD equipment on site, it can be set at 20 × Inspect and clean the crystal end face under the microscope.

6 - Connection and installation of ten thousand watt LOE output head and cutting head

1 - Visually inspect the cutting head assembly area and the rubber ring surface. If any foreign matters are found, clean them with a dust-free cloth dipped in alcohol;

2 - According to the assembly requirements, install the qualified LOE back to the cutting head and lock the screws to complete the assembly (Figure 13, Figure 14, Figure 15).

3 - If it is not necessary to assemble the cutting head, seal the LOE port with a clean protective film, install and lock the dust cap, and finally put the LOE back in place.
