Problems solved by technology

[0003] The fiber threading process in the production of optical fiber connectors involves fiber threading, length fixing, glue injection and curing. The current production method of the existing technology is to manually fix the product on the tooling fixture, and then carry out fiber threading, Fixed length, glue injection and curing, so the performance parameters and size parameters of the product can only be guaranteed by the accuracy of the fixture and the proficiency of the workers

For fiber threading, if the accuracy of fixtures cannot be guaranteed, then the dimensional parameters of the product will not be guaranteed, or fiber breakage is prone to occur during assembly; for glue injection, the current method is to use hand-held Type glue injection machine for glue injection, the amount of glue is completely controlled by the workers according to their proficiency, so some of the produced products need secondary glue replenishment, or some glue quantity is too much and needs to be scraped

However, in the production process, the fixtures are worn for a long time, and the accuracy is difficult to be guaranteed for a long time. If the production time is longer, the fixtures will be worn more seriously. Therefore, it is time-consuming and laborious to maintain the fixtures for a long time; and this process is currently All manual operations are used, so the human factors in this process have a great influence, and the dimensional parameters cannot be accurately controlled; generally speaking, the optical connectors have relatively high requirements on performance parameters and dimensional parameters, so the wear and tear of the fixture and artificial Differences in factors lead to product performance changes and fluctuations, making it difficult to achieve product consistency

[0004] Comprehensive appeal, the current fiber threading process in the production of optical fiber connectors has low efficiency in the existing technology, frequent maintenance of fixtures and fixtures, large influence of artificial factors, difficult control of dimensional parameters and performance parameters, and difficulty in achieving product consistency, thus affecting optical fiber. The life of the connector and the successful coupling rate and other issues
