Maintenance and replacement of optical fiber laser hand-held welding head lens

Maintenance and replacement of protective mirrors

The welding effect is not good, but the welding protection mirror is normal, and there is a burning spot detected by the optometry

When the lens is damaged, it is usually caused by the contamination of the collimating protective lens or the focusing protective lens. At this time, after-sales personnel are required to check whether the lens has burning spots. Before inspection, wipe the exterior with a lint-free cloth dipped in alcohol.

The disassembly and assembly of the welding protection mirror, the disassembly method is shown in the following figure

Welding protection mirror drawer structure diagram, as follows:

Maintenance and replacement of collimator lenses

Remove 3 screws one by one, disassemble and assemble the lens wrench, remove the collimating protective lens and the collimating lens for maintenance and maintenance, pay attention to the direction of the collimating lens when installing, do not install it in reverse, and the convex side faces the nozzle.

Cleaning of the collimator

① Use tools: clean cotton swabs, isopropyl alcohol, and fill with dry and pure compressed air.

② Spray isopropyl alcohol onto the dust-free swab.

③ Gently pinch the side edge of the lens with your left thumb and index finger.

④ Hold the dust-free swab in the right hand, and gently wipe from bottom to top or from left to right in a single direction.

Wipe the front and back sides of the lens, and blow the surface of the lens with filled dry and pure compressed air to make sure

Confirm that there is no foreign matter on the lens surface after cleaning.

⑤ The cleaned collimating lens must be installed in the collimating lens holder as soon as possible and inserted into the welding head.

Maintenance and replacement of focusing lens

Remove the two parts in turn, remove and install the lens wrench and remove the focusing lens for maintenance and maintenance. When installing, pay attention to the direction of the focusing lens, do not install it backwards, and the convex side faces the optical fiber.

Cleaning of the focusing lens

① Use tools: clean cotton swabs, isopropyl alcohol, and fill with dry and pure compressed air.

② Spray isopropyl alcohol onto the dust-free swab.

③ Gently pinch the side edge of the lens with your left thumb and index finger.

④ Hold the dust-free swab in the right hand, and gently wipe from bottom to top or from left to right in a single direction.

Wipe the front and back sides of the lens, and blow the surface of the lens with filled dry and pure compressed air to make sure

Confirm that there is no foreign matter on the lens surface after cleaning.

⑤ After cleaning, the focusing lens must be installed in the focusing lens holder as soon as possible, and the whole welding process must be completed.
