Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims to the benefit of priority from Chinese Application No. 202411583469.2 with a filing date of Nov. 7, 2024. The content of the aforementioned applications, including any intervening amendments thereto, are incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to the technical field of optical fiber jumper grinding, in particular to an automatic grinding line for grinding MPO (multi-fiber push on) optical fiber jumper. BACKGROUND The polishing of MPO (multi-fiber push on) optical fiber jumper is generally divided into five processes namely degumming, coarse grinding, fine grinding, fiber drawing, and polishing. In each process, separate grinding fixtures need to be assembled and grounding or polishing performs on a separate optical fiber grinding machine. However, due to the pigtail of the MPO optical fiber jumper is long, the weight of a reel of MPO optical fiber jumper can generally reach 50-100KG, thus, when using separate optical fiber grinding machine for grinding or polishing, it is necessary to disassemble the grinding fixture to clean the end face of the MPO optical fiber jumper after the grinding or polishing is completed, then the grinding fixture is assembled on optical fiber grinding machine of the next process to continue grinding. As the pigtail of the MPO optical fiber jumper is heavy, the turnover of the MPO optical fiber jumper during grinding is inconvenient, thereby lowing the grinding efficiency. SUMMARY In order to solve the above technical problems, the purpose of the present disclosure is to provide an automatic grinding line for grinding MPO optical fiber jumper.
