Abstract
The utility model relates to a detecting device, in particular to a detecting device for optical fiber coating abnormality, belonging to the technical field of optical fiber detection. The detecting device for the optical fiber coating abnormality comprises an optical fiber winder and a microscope, wherein the signal output end of the microscope is connected with the signal input end of a host; amicroscope stage is provided with a clamp holder which is provided with a through hole in the middle; and an optical fiber clamp is arranged in the clamp holder, therefore the image information of theoptical fiber coating can be collected by means of the microscope and output to the host, the detection information of the optical fiber coating can be obtained, and the abnormal phenomena of the optical fiber coating can be judged.
Description
Technical field
The utility model relates to a kind of pick-up unit, and especially a kind of fibre coating abnormal detector belongs to optical fiber detection technique field.
Background technology
Optical fiber technology is widely used in fields such as medical treatment, aviation, communication; the be not collided influence of unfavorable factors such as friction, moisture of the claimed optical fiber in many uses field of optical fiber (for example communication); fiber optic protecting method commonly used now is to smear at optical fiber surface to cover protective seam; but this fibre coating regular meeting in process of production produces unusual; for example have impurity, random stripe and bubble etc., fibre coating can influence performance behind the optical fiber cabling unusually.The abnormality detection of fibre coating is not applied in the optical fiber manufacturing industry as yet, only has a small amount of optical fiber manufacturing enterprise to pay attention to the unusual detection of fibre coating.The detection method that optical fiber manufacturing enterprise uses at present has multiple, a kind of method commonly used is optical fiber to be placed directly in microscopically detect by an unaided eye, can also utilize the additional function of other checkout equipment to detect in addition, these equipment all exist the optical fiber sample the detection limited length, detect problems such as inaccurate.Understand according to the applicant, the optical fiber industry still lacks the device that can detect unusually fibre coating accurately, easily so far.
The utility model content
The purpose of this utility model is: at the shortage of above-mentioned prior art, propose a kind of fibre coating abnormal detector that can detect fibre coating accurately, easily.
In order to reach above purpose, fibre coating abnormal detector of the present utility model comprises fibre optic winder and microscope, described microscopical signal output part connects the signal input part of main frame, its improvements are, have the gripping device of through hole in the middle of on described microscopical objective table, being provided with, in the described gripping device fiber clamp is installed.
Like this, just can collect the image information of fibre coating, and output to main frame, obtain the detection information of fibre coating, judge whether fibre coating exists abnormal occurrence by microscope.
Fibre coating abnormal detector of the present utility model adopts fiber clamp that optical fiber is accurately located, can obtain the coating information of the fiber segment of required detection by microscope quickly and accurately, and be transferred in the main frame by the image transmission line, thereby to fibre coating whether exist unusually, out-of-the way position and size make accurate judgement, in addition by rotating the handle of fibre optic winder, optical fiber can be moved in microscopical pandown, so just can obtain the coating information of whole optical fiber, solve the length restriction in the past detecting.

Embodiment
Embodiment one
The fibre coating abnormal detector of present embodiment, as shown in Figure 1, comprise fibre optic winder 2, microscope 4 and be arranged on optical fiber locator 3 on microscope 4 objective tables, the objective table of microscope 4 is a rectangular platform that can move along X, Y both direction, the adjusting button of X, Y direction is installed on it, and the signal output part of microscope 4 connects the signal input part of main frame 1.Extremely shown in Figure 4 as Fig. 2, optical fiber locator 3 comprises glassware 6, gripping device 7 and the fiber clamp 8 that is installed in the gripping device 7, glassware 6 is provided with the cross section and is circular groove, the gripping device 7 that the cross section is an annular is installed in it, the centre of gripping device 7 has through hole, fiber clamp 8 is complementary with shape of through holes, be provided with viewport 9 at the middle part of fiber clamp 8, viewport 9 is provided with pressing plate 10, pressing plate 10 is a transparent panel, by screw retention on fiber clamp 8, the middle part of fiber clamp 8 also is shaped on horizontal V-type groove 11, on gripping device 7, be shaped on the guide channel 12 corresponding, make optical fiber to enter easily in the V-type groove 11 by guide channel 12 with V-type groove 11.
During real work, in glassware 6, fill with earlier optical fiber matching fluid (refractive index of optical fiber matching fluid is determined according to the refractive index of tested optical fiber), do not produce bubble, end with testing fiber is fixed on the pay off rack 5 of fibre optic winder 2 again, the other end of optical fiber passes from optical fiber locator 3 along route guide channel 12, V-type groove 11, viewport 9, so that observe, optical fiber one end that passes sticks on the reel of fibre optic winder 2 with fiber orientation.Then, X, the Y direction of regulating the focal length of microscope 4 and adjusting objective table are regulated button, find target to be observed, observe fiber segment to be detected by the camera lens of microscope 4 and the viewport 9 on the fiber clamp 8, and signal is input to main frame 1, in the display screen of main frame 1, show the image of fiber segment coating to be detected, judge at last whether fibre coating exists abnormal occurrencies such as impurity, random stripe and bubble, further detect unusual size by image analysis software.In addition, can also make optical fiber moving by rotating the handle of fibre optic winder 2, thereby obtain the coating information of whole optical fiber in the pandown of microscope 4.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
