A concrete example optical cable being carried out to strip operation is described below with reference to Fig. 1-5.
The first step: load optical cable
By operating personnel, the end of 1～18 cable to be denuded is put on optical cable plummer 10 successively, the outstanding length of optical cable 20 is controlled by a block 92 placing its front portion.Afterwards, will utilize optical cable clamp device 70 that optical cable 20 is compressed and fixed.
Second step: on optical cable plummer 10, laser instrument is set
The optical cable plummer 10 that carries optical cable is placed in to laser instrument objective table (corresponding to support 90).
The 3rd step: cut cable jacket 21
Start laser instrument cutting process, laser instrument objective table is cut movement of optical cables to time under laser instrument camera lens by initial Article 1 and is opened and launch laser, objective table continues carrying optical cable at the uniform velocity passes by laser beam, and movement velocity is generally in 50～150mm/ second, laser instrument is made up of the laser head of upper and lower two same models and function, while cutting, first launch continuous laser pulse by upper laser head (corresponding to upper laser instrument 31) or lower laser head (corresponding to lower laser instrument 32), the energy intensity of laser pulse is between 8～15W, the optical cable energy of general diameter 2.0mm low smoke and zero halogen is chosen as 10W left and right, optical cable will be by surface trimming at its cable jacket after laser pulse by optical cable plummer 10, complete bottom (now under laser head, camera lens the goes out laser) cutting to optical cable after being turned back by platform again after the cutting of first half optical cable.Now two demifacets up and down on the face of cylinder of every optical cable have all been cut two smooth otch, and this notch depth needs to control, and can find proper power by regulation and control laser instrument emissive power.
The 4th step: cable jacket 21 is peeled off
After each optical cable is cut on upper and lower both direction by laser instrument, by sheath clamp cutting edge (corresponding to the lower clamping section 72 of optical cable clamp device 70) by sheath be pulled away from the compression of briquetting (corresponding to the upper clamping section 71 of optical cable clamp device 70) all cut optical cable, be pulled away from by sheath the motion a (Fig. 3) that control gear (corresponding to clamp device driver 74) controls again and move to the left all cable jackets of being cut optical cable 21 are pulled away from, thereby complete automatically peeling off many cable jackets simultaneously.
The 5th step: aramid fiber (drawing corresponding to Kev) cutting
After completing the sheath of optical cable peeled off, optical cable carrying fixture will be turned right and be done translation motion (motion in Fig. 3 c), mobile 6～10mm, the object of translation is not change under the condition of laser instrument cutting track, make the cutting position of laser than the position relative reach 6～10mm on optical cable that previously cut sheath, this numerical value is exactly to retain the length of aramid fiber on optical cable, and concrete numerical value will be according to the model of the different joints of optical fibre and manufacturer and slightly different, generally in 7mm left and right.
After completing optical cable and retreating, laser instrument objective table will carry optical cable through a valve (corresponding to air jet system 60) of from top to bottom blowing, this valve all optical cable through process under it in blowing compressed air continuously all the time, the order ground of blowing is the aramid fiber of the optical cable through its below and 900um coat need to be separated, to facilitate the cutting of follow-up aramid fiber.The air pressure that blowing nozzle uses is about 2～4kg/cm
2.Aramid fiber (if the motion in Fig. 4 is d) by past blowing down completely separated with the optical cable of 900um part, is stuck in rectangular frame part 50 simultaneously and can not recovers position by the aramid fiber toward blowing down when through blowing nozzle; Now aramid fiber cut-out baffle plate 40 moves to the motion b as in Fig. 3 between 900um optical cable below and aramid fiber, and the object that adds this baffle plate is that catch will stop laser in order to avoid cut wound 900um optical cable coating layer in the process of cutting off aramid fiber.
The 6th step: take off optical cable plummer 10 from laser instrument objective table, complete this operation.
Utilize technical scheme of the present invention, at least can obtain one of following advantage:
Use cut to avoid loss and the plant maintenance of current plant equipment or peel manually cable instrument blade;
Realize and once shell many optical cables, improved production efficiency;
Use pressurized air to blow to 0.9mm optical fiber and the Kev pull portion of the optical cable of peelling off cable jacket, make Kev draw light separation, make cut Kev draw effective convenience.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can change these embodiment.The scope of application of the present invention is limited by claims and equivalent thereof.The scope of the present invention, should as the application claim defined is as the criterion.
