【摘要】：进入九十年代以来,随着因特网技术的发展,对传输频宽的要求也快速的增加,这就使光通讯产业得到了快速的发展。目前,国家正在加快建设以光纤为主体的大容量数字通信干线,大容量光缆通信以覆盖全国,光纤已成为通信网络的重要传输媒介。目前世界的通信业务经光纤传输的大约占到60%-80%,但从整体的光纤通信水平来看,光纤通信的还具有很大的发展潜力,其产业的发展速度仍然很快,高速发展的光纤通信网络为电子元件的应用的发展提供了广阔的空间。而作为光纤通信的重要应用部件的光纤接头也得到了长足的发展,作为光纤接头的核心部件的陶瓷插针和陶瓷套简的需求量也是非常巨大的。据报道,世界通信市场上每月大概需要3000万只陶瓷插针,但其实际的市场生产能力只有2000万只,缺口大约是30%,与其配套的陶瓷套筒也是处在这个水平。世界市场对陶瓷套筒的巨大需求决定了对陶瓷套筒的开发具有很巨大的多方面的意义,从而具有自主产权的陶瓷套筒生产技术的研发的成功就能够取得巨大的经济效益；因此经济适用的相关生产设备、检测设备的研制成功将使能够保证成功研制将大大缩短新品种陶瓷套筒的研发周期,陶瓷套筒的孔径测量分选系统的研究对开发氧化锆陶瓷套筒的孔径的测量检测将会具有很重要的现实意义。本文主要研究薄壁陶瓷元件孔径测量分选系统,根据系统生产的工艺要求,提出了以工业触摸屏为现场人机界面,以西门子S7-200PLC为核心控制器,通过PLC控制步进电机,驱动精密线性模组及滚珠丝杠副,实现陶瓷套筒的测量分选的方案。本文首先设计了陶瓷套筒测量分选系统的总体结构,根据具体要求和实际情况,将系统分为上料部分、测量部分、分选部分以及测量控制软件部分,并分别介绍了各部分的原理及实现方法。本文根据套筒的结构及系统工作的实际情况,选择振动料斗上料的方式,并设计了振动排序以及防堵塞结构,是陶瓷元件以一定的姿态进入到测量装置中。在测量装置中,利用压力传感器测量陶瓷套筒与探针分离的过程中所产生的插拔力不同,间接反映陶瓷套简内径不同,从而将陶瓷套筒分为不同的等级。分选机构则是通过步进电机带动导料筒转动,从而将内径不同的套筒分选到相应的分选槽中。本系统通过触摸屏实现系统的启动、停止以及点动调试,并在触摸屏上实现各个等级的套筒数量的统计以及当天生产量的统计。并通过ANSYS软件,对陶瓷套筒在测量分选过程中的应力和变形情况进行分析,确保测量过程元件所受的应力在陶瓷套筒所允许的应力范围内,即测量分选过程不会对陶瓷套筒产生破坏。
[Abstract]:Since the 1990s, with the development of Internet technology, the requirement of transmission bandwidth has been increasing rapidly, which has made the optical communication industry develop rapidly. The country is speeding up the construction of a large capacity digital communication trunk line with optical fiber as the main body, and large capacity optical cable communications to cover the whole country. Optical fiber has become an important transmission medium in communication networks. At present, about 60%-80% of the world's communication services are transmitted through optical fibers. However, judging from the overall level of optical fiber communication, optical fiber communication still has great potential for development. The rapid development of optical fiber communication network provides a wide space for the application of electronic components. As an important application component of optical fiber communication, optical fiber connector has also been greatly developed. The demand for ceramic pins and ceramic jackets, which are the core components of fiber optic connectors, is also enormous. It is reported that about 30 million ceramic pins are needed in the world communications market every month, but the actual market capacity is only 20 million. The gap is about 30%, and the matching ceramic sleeve is also at this level. The huge demand for ceramic sleeve in the world market determines that the development of ceramic sleeve is of great significance in many aspects. Thus, the success of the research and development of ceramic sleeve production technology with independent property rights can achieve great economic benefits. The successful development of the testing equipment will make it possible to ensure that the successful development of the new type of ceramic sleeve will greatly shorten the research and development cycle. The study of the aperture measurement and sorting system of ceramic sleeve will be of great practical significance for the development of the measurement and detection of the aperture of zirconia ceramic sleeve. According to the process requirements of the system, the industrial touch screen is used as the field man-machine interface and Siemens S7-200PLC as the core controller. The stepper motor is controlled by PLC to drive the precision linear module and the ball screw pair. This paper first designs the overall structure of the ceramic sleeve measuring and sorting system. According to the specific requirements and the actual situation, the system is divided into feeding part and measuring part. The principle and realization method of each part are introduced respectively. According to the structure of the sleeve and the actual working condition of the system, the way of feeding the vibrating hopper is selected in this paper. The vibration sorting and anti-clogging structure are designed. The ceramic element enters the measuring device with a certain attitude. In the measuring device, the insertion force produced in the process of separating the ceramic sleeve from the probe by using the pressure sensor is different. Indirectly reflecting the different internal diameter of the ceramic sleeve, the ceramic sleeve is divided into different grades. The sorting mechanism is driven by the stepper motor to drive the guide tube to rotate. Thus the sleeve with different inner diameter is sorted into the corresponding sorting slot. The system realizes the system start, stop and point debugging through the touch screen. On the touch screen, the statistics of the number of sleeve and the daily production are realized. The stress and deformation of ceramic sleeve in the process of measuring and sorting are analyzed by ANSYS software. Ensure that the stress of the measuring process element is within the allowable stress range of the ceramic sleeve, that is, the measuring and sorting process will not damage the ceramic sleeve.
