Description

Technical Field

[0001] This invention belongs to the field of optical fiber processing technology, and in particular relates to an automatic wiping device for large-diameter multi-core optical fibers. Background Technology

[0002] After the optical fibers are bundled and polished at the branch ends, the fiber end face needs to be wiped to avoid the presence of stains. Then, the fiber end face is inserted into the end-of-line tester to check the condition of the fiber end face. Currently, the process requires one person to use paper and water (reagent or alcohol) to repeatedly wipe and plug and unplug the fiber until the end face is completely free of stains.

[0003] In the existing technology, cleaning the fiber end face mainly relies on manual operation. Wiping the end face requires a person with skilled skills and experience, which is time-consuming and labor-intensive. Repeated wiping may also damage the fiber end face, making it impossible to achieve an automatic and efficient wiping process.

[0004] At the same time, accurately locating and wiping stains on a single fiber in a multi-core fiber optic network also presents certain challenges.

[0005] Therefore, designing an automatic wiping device that can wipe the end face of optical fibers and remove stains from the end face of large-diameter optical fibers is a problem that needs to be solved by those working in this field. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic wiping device for large-diameter multi-core optical fibers. The fiber fixing mechanism is used to secure the optical fiber for subsequent end-face inspection, and the wiping mechanism is used to clean the stains on the end face of the optical fiber. By designing a sliding base, the fiber fixing mechanism and the wiping mechanism can be quickly switched. It can automatically clean the end face of the optical fiber after detecting stains, without the need for manual wiping, and has high wiping accuracy and high working efficiency.

The dirt on the fiber end face is collected by the image acquisition point of the end face detector through the light blocking ring 104, the acquisition port 103 and the positioning sleeve 203.

[0057] The reagent is drawn from the reagent box 402 by the micro pump body 401 and output to the wiping paper between the two guide roller groups 306 through the rigid thin tube 404, so that the wiping paper has the reagent used for cleaning.

[0058] After detecting the stain, the cylinder 5 controls the slide 102 to slide along the slide rail 101 until the wiping paper between the two guide rollers 306 is moved to the position of the stain. The pneumatic telescopic seat 301 is controlled to extend and drive the wiping paper to stick to the end face of the optical fiber. The micro motor 308 is controlled to drive the unwinding paper roll 304 and the rewinding paper roll 305 to run synchronously through the cooperation of the gear 307 and the toothed belt 309. At the same time, the micro motor 308 is continuously controlled to continuously rotate forward and reverse, so that the wiping paper and the end face of the optical fiber can wipe up and down, thus wiping the stain.

[0059] After the stains are wiped off, control cylinder 5 to reset, and then check again with the end face detector whether it is clean.
