Defect detecting device used for air-blowing mini-type optical cable jacket surface

Abstract

The invention relates to a defect detection device used for an air-blowing mini-type optical cable jacket surface. The defect detection device used for the air-blowing mini-type optical cable jacket surface comprises a detection seat sleeve. The detection seat sleeve is composed of an upper seat sleeve and a lower sleeve in a half-and-half opening and closing mode. Cable penetrating through holes are formed in the middles of the upper seat sleeve and the lower seat sleeve. One sides of the upper seat sleeve and the lower seat sleeve are connected in a hinged mode through a tensioner. Half-and-half sizing dies are arranged at the front ends and / or the rear ends of the upper seat sleeve and the lower seat sleeve in an installation mode. Contact alarm switches are arranged on the other sides of the upper seat sleeve and the lower seat sleeve in a configured mode. An aberration reflecting type detector is arranged in an installation mode on the circumference, along the cable penetrating through holes, of the detection seat sleeve. The defect detection device used for the air-blowing mini-type optical cable jacket surface has the advantages that due to the device is installed in a production process of a air-blowing mini-type optical cable, the whole segment length is detected, the defects of the optical cable surface can be effectively detected, detection precision is high, risks of air-blowing construction are avoided, due to adoption of the aberration reflecting type detector, the possible defects on each position of the air-blowing mini-type optical cable surface can be detected, precision is high, and therefore detection omission to small material dropping points of the mini-type optical cable is avoided. According to the detection seat sleeve, a structure of the upper seat sleeve and the lower seat sleeve in a half-and-half opening and closing mode is adopted, and use and installation are convenient to achieve.

Description

technical field [0001] The invention relates to a sheath surface defect detection device used in the production process of air-blown micro-optical cables. Background technique [0002] With the continuous development of optical communication networks, pipeline resources are becoming more and more scarce, and micro-optical cables laid by air blowing are more and more widely used. Compared with ordinary optical cables, air-blown micro-optical cables have small diameter, light weight, thin sheath wall thickness, and the minimum thickness is only 0.3mm. , the optical cable needs to pass through a sealing ring with a certain diameter, and it is required to be able to withstand the air blowing pressure of 12bar. If there is a small bulge in the cable sheath, it may cause the cable to fail to pass through the sealing ring and cause the cable to break, or because there are micropores on the surface of the sheath. All will cause the gas to enter the cable core from the stripping poi...

Problems solved by technology

For air-blown micro-optical cables with thinner wall thickness, if the defect point is small, it has little effect on the diameter. This kind of through-beam detection system is difficult to inspect. serious
