Description

一种切割定位式光纤熔接装置 技术领域
[0001] 本发明涉及光纤熔接技术领域， 具体涉及一种切割定位式光纤熔接装置。
背景技术
[0002] 光纤熔接机是一种靠放出电弧形成的高温将两头光纤熔化， 同时运用准直原理平缓 推进， 以实现光纤模场的耦合的通信工程设备， 被广泛用于通信工程施工、 维护、 通信设备 生产制造中。 上世纪 70 年代第一台光纤熔接机诞生于德国西门子公司， 当时采用的是乙炔 火焰熔接， 逐渐发展到依靠显微镜观察光纤接续端面 （经切割后端面） 在三维空间 （X、 Y、 ζ轴） 的位置并手动调整使其精度对准， 达到要求后在电极放电型成的高温空间内继续推进 (Ζ轴方向） 一段距离使接续部位达到熔融状态并接续在一起。 上世纪 80 年代后期至现在， 经过不断的技术演进， CCD 成像及其成像后的图型分析技术取代了人工显微观察， 步进电 机及其高精度推进技术也取代了手工调校对准， 随着单片机性能的不断提高及其相关技术的 不断演进光纤熔接机的性能、 速度以得到很大程度提高。 充分的市场竞争也导致了设备的价 格从上世纪 90年代 30-40万人民币每台的价格降到目前 2-6万人民币的价格。
[0003] 目前市场上大约有 7-8种品牌的光纤熔接机， 其工作原理和使用过程基本上是一样的， 即
( 1 ) 准备光纤端面。 在熔接前通过光纤切割刀来制备切面垂直于轴线的端面， 只有这样才 能在接续过程中以端面为界面完成对准。
[0004] (2) 放置光纤接续。 将切割后的光纤放在熔接机的 V型槽中， 压上夹具， 后按下接 续键， 系统通过镜头和 CCD 获取光纤的三维图像， 并据此分析和指导熔接机的机械系统调 节光纤位置相向移动， 当光纤端面之间的间隙合适后停止移动， 设定初始间隙， 熔接机测量， 并显示切割角度。 在初始间隙设定完成后， 开始执行纤芯或包层对准， 然后熔接机减小间隙 (最后的间隙设定）， 高压放电产生的电弧将左边光纤熔到右边光纤中， 最后微处理器计算 损耗并将数值显示在显示器上， 接续完成。
[0005] 本发明是对申请号为 2012100953322.X 专利的进一步地改进， 在申请号为
2012100953322.X 的专利中待接光纤由定位机构固定定位， 待接光纤交叉斜放置在定位机构 中的光纤定位总成上， 切割后的光纤依靠光纤自身应力回位对准。 这种仅依靠光纤自身应力 回位对准的方式， 光纤不易对准。
[0006] 本发明结构简单、 性能可靠、 具有很好的成本优势， 特别适用于光纤到户工程施工。 发明内容 [0007] 针对上述现有技术， 本发明的目的在于提供一种切割定位式光纤熔接机， 其旨在解 决切割后的待熔接光纤对位不准确， 影响到熔接质量的问题。
[0008] 为了解决上述技术问题， 本发明采用如下技术方案：
一种切割定位式光纤熔接装置， 其特征在于， 包括主体载体以及设置在主体载体上的滑块总 成、 Z轴馈入组件、 击锤组件、 压锤组件、 光纤定位组件， 所述光纤定位组件由光纤定位座、 铰接在光纤定位座上的光纤压夹、 设置在光纤定位座间的两块胶垫和设置在击锤组件上配合 光纤定位座间的胶垫使用的两块胶垫构成， 所述光纤定位座包括左光纤定位座和右光纤定位 座， 其上都设有 V型沟道， 待熔接光纤放置在 V型沟道内和胶垫上， 放置在胶垫上的光纤 段经上下两组胶垫固定。
[0009] 进一步地， 所述 Z 轴馈入组件在熔接光纤时， 为了避免切割后两端光纤端面相互接 触造成端面损伤， 先将切割后的光纤拉开， 在放电熔接前再馈入补偿。
[0010] 所述 z轴馈入组件至少包含有微位移器， 使光纤定位座移动并带动光纤轴向移动。
[0011] 进一步地， 所述滑块总成包括滑块载体、 切割刀片、 位置调节支架、 V型槽和安装在 V 型槽上的电极， 所述切割刀片设置在滑块载体上， 所述 V 型槽设置在位置调节支架上， 位置调节支架与滑块载体固定。
[0012] 进一步地， 所述压锤组件包括压锤、 压锤安装座、 弹簧， 所述压锤安装座安装在主 体载体上且与滑块总成处于同一轴线上， 所述压锤经弹簧的弹力将待熔光纤压在 V 型槽上。
[0013] 进一步地， 所述光纤定位座为了适应不同规格型号的光纤以及光纤成端结构的接续， 在接续前应更换成对应的光纤定位座， 每套成品熔接机配置了常用的型号光纤定位座。
[0014] 所述压锤经手动控制动作或经电动控制动作。
[0015] 切割定位式光纤熔接装置， 还包括电气控制系统， 该电气控制系统主要由 CPU、 位 置传感器、 微位移器、 放电电极、 电极放电控制模块、 高压线圈和辅助功能模块构成； 位置 传感器设置在切割并熔接光纤的滑块总成上， 微位移器与 CPU连接， 安装在光纤压夹处， 放电电极全部安装在滑块总成上， 电极放电控制模块与 CPU连接， 控制放电电极放电， 高 压线圈与电源模块连接， 给放电电极供电， 电源模块与 CPU连接。
[0016] 进一步地， 所述位置传感器将放电对准待熔光纤的位置信号传输至 CPU, CPU 分析 处理后使微位移器上光纤在 Z轴方向上馈入一定距离的同时； CPU指令电极放电控制模块 控制高压线圈为放电供电， 熔接光纤。
[0017] 本发明的原理为： 在切割前将两段清洁后的需接续光纤相向布放在同一轴线上， 利 用击锤组件上的胶垫和光纤压夹间的胶垫配合以及光纤压夹固定光纤， 滑动总成滑动一次同 时划伤两根光纤随后经击锤组件击断上述待接续光纤完成切割， 压锤组件中的压锤将切割好 的光纤压紧固定在 V型槽上；
熔接时待熔接光纤经 z轴馈入组件在切割光纤完成光纤在击锤作用下尚未归为时， 为了避免 切割后的光纤端面彼此由于触碰， 破坏端面先拉开一段距离， 在放电熔接前再馈入补偿， 这 样保证了熔接质量； 滑块总成将 V 型槽、 切割刀片和滑块集成为整体结构， 这样使待熔接 光纤对准更为准确； 由于整个作业过程是在滑块总成内进行的， 利用滑块总成本身精度在 X、 Y轴方向能满足接续要求。
[0018] 综上所述， 本发明能快速便捷的将两根未切割的光纤处理成为在 X\Y\Z 轴三维空间 内满足放电接续前的要求的光纤， 这种状态下的光纤只需要按照事先设定的放电参数和电极 放电时的 Ζ轴馈入参数执行就能完成光纤接续。 发明人经过多次试验， 经测试这些接续点的 合格率不低于 92%， 因此， 这种光纤接续方式完全能满足现有工程需求。 值得注意的是， 整 个接续过程并没有传统的光学镜头和 CCD以及图像处理系统参与。
与现有技术相比， 本发明的有益效果表现在：
一、 摒弃以获取动态接续图像并以分析此图像的方式驱动调芯熔接的方式， 而是利用滑块总 成的精度定位光纤， 在切割前将两段清洁后的需接续光纤相向布放在同一轴线的光纤定位座 的 V 型沟道内， 一次同时划伤两根光纤随后击断上述需接续光纤完成切割， 切割击断后的 微弯光纤段在压锤作用下压在滑块总成上的 V 型槽内， 由此达到既切割了光纤又使切割后 光纤在 V 型槽、 压锤和胶垫配合的作用下对准的效果， 经放电和端面的推进完成光纤熔接; 二、 利用光纤切割形成的光纤端面位置经 Z轴馈入组件先行拉开， 在放电熔接时再补偿， 这 样有效保证了熔接质量； 利用滑块总成上 V 型槽精度满足了光纤放电接续前的条件， 省去 了大量的机电设备， 大大精简了现有光纤熔接机结构， 结构更简单， 降低了生产成本； 并降 低了成本减少了作业程序， 实现了真正的单人操作。
