In order to solve the problems of direction identification and adjustment in the traditional feeding method of optical fiber connector ceramic ferrules, a fully automatic feeding system solution was proposed, and the core component of the system, the rotating platform was designed. The rotating platform uses a photoelectric detector to identify the two different end faces of the ceramic ferrule, and adjusts the ceramic ferrule to the correct direction through a rotating rod installed in the center of the rotating platform. The system can complete part identification, adjustment and feeding in one process, effectively solving the problem of feeding ceramic ferrules. The fully automatic feeding system was applied to the ceramic ferrule precision grinder and a production test was carried out. According to the statistical data of the test and the comparison before and after adopting the fully automatic feeding system, the use of this system can not only meet the production requirements of the parts, but also improve the production efficiency, reducing the labor force, and the product qualification rate is significantly improved. Meanwhile, the design of this system provides a reference for the design of feeding systems for similar products.
Due to the requirements of micro-hole processing of ceramic ferrules, the precision spindle of the micro-hole grinder was designed. In order to verify the rationality of the design, the finite element analysis software ANSYS Workbench was used to conduct finite element modeling of the spindle, and modal analysis was performed on the spindle. The first six orders of natural frequency, vibration shape, critical speed and other dynamic characteristics of the spindle were analyzed. According to the analysis results, the maximum working speed of the spindle is far lower than 75% of its first-order critical speed, effectively avoiding the resonance zone and verifying the rationality of the spindle design. At the same time, this research provides a reference for the design and simulation of similar products.
