基于PC的光纤端帽熔接控制装置 Fiber end cap welding control apparatus PC

技术领域 FIELD

[0001] 本发明属于激光技术领域,尤其涉及一种光纤端帽熔接控制装置,本发明主要用于制作大功率传能光纤,大功率传能光纤制作中的核心技术是光纤端帽的熔接。 [0001] The present invention belongs to the field of laser technology, and particularly to an optical fiber end cap welding control apparatus, the present invention is mainly for the production of high-power laser delivery fiber, the core technology of optical power transfer can produce the optical fiber is welded end cap. 本发明主要涉及光纤与大尺寸石英端帽熔接装置的控制系统搭建。 The present invention relates to a control system and large-sized quartz fiber welding device end cap structures.

背景技术 Background technique

[0002] 高功率激光光纤传输存在以下待解决问题:1、光纤芯径很细,高功率激光通过透镜聚焦进入光纤,光纤端面的功率密度极高,光纤很容易损坏,所以要求光纤端面无任何损伤及污染,要求极为苛刻;2、光纤端面面积很小,不容易进行镀膜处理,激光进入无镀膜光纤端面存在较大的损耗,会产生更多损坏光纤的热量;3、裸光纤两端头在安装、拆卸过程中强度低,加持很不方便。 [0002] High power laser optical transmission The unresolved problems: 1, the fiber core diameter is very small, high power laser into the optical fiber through the lens is focused, very high power density of the fiber end faces, optical fibers are easily damaged, it requires no fiber end damage and pollution, the most demanding; 2, fiber end area is small and hard coating processing, laser light enters the fiber end face without coating there is a large loss heat is generated more damaging the fiber; 3, head bare fiber ends low intensity installation, removal, blessing inconvenient.

[0003] 通过在光纤两端熔接大尺寸阶梯型光纤端帽,并在端帽两端进行镀膜处理可完全解决光纤端面功率密度高、损耗大及不方便加持的问题。 [0003] completely address the high power density through the fiber end faces at both ends of the fiber optical splice large stepped end caps, and end caps at both ends of the coating process, a large and inconvenient to loss problem blessing.

[0004] 高功率传能光纤是光纤耦合输出固体激光器及光纤激光器的必备器件,因此大尺寸阶梯型光纤端帽熔接装置的开发有很大实际意义。 [0004] High-power laser delivery fiber is a fiber-coupled solid-state laser and a fiber laser device essential, so the development of a large-sized optical fiber end cap stepped welding apparatus has a great practical significance.

[0005]目前国内外光纤熔接系统主要应用于光纤与光纤熔接,或者光纤与直径2_以下的石英端帽熔接,并不能用于光纤与大尺寸石英端帽熔接,同时普通熔接机的工作原理也不适合将光纤与大直径石英端帽的熔接。 [0005] It is mainly used in domestic and optical fiber splicing system and fiber splice or fiber diameter of less 2_ fused quartz end cap, and can not be used with a large-sized quartz fiber end cap weld, while the principle of the ordinary welding machine not suitable for large-diameter optical fiber with fused quartz end cap.

[0006] 本发明为了解决光纤与大尺寸端帽的熔接搭建了大尺寸阶梯型光纤端帽熔接装置,为获得精准的熔接效果,该装置采用自动化控制程序进行控制。 [0006] In order to solve the large size of the fiber and the end cap weld build large stepped end cap fiber welding apparatus, welding to obtain accurate results, the apparatus uses a control program for controlling the automation. 本发明根据光纤与大尺寸石英端帽熔接机理,其熔接过程可分为预热过程、熔接过程与冷却过程三个阶段,熔接过程的三个阶段依次顺序执行且各阶段激光功率不等。 According to the present invention an optical fiber with a large-sized mechanism fused quartz end cap, which can be divided into pre-fusion process, fusion process and cooling process in three stages, the three stages of the fusion process are sequentially performed and the order of the various stages of the laser power range. 而目前激光加工设备采用的控制系统在加工过程中激光功率均保持恒定值,即无法实现时时在线调节。 And the control system is currently employed in the laser processing apparatus processing a laser power value are kept constant, i.e., adjustment can not be achieved always online.
