AI Technical Summary

Problems solved by technology

[0006] 1. After the problem is detected, there is no picture, and manual judgment cannot be made
[0007] 2. Since the laser is a parallel light source, using two or three sets of lasers will produce blind spots, and using more sensors will bring additional costs and blind spots cannot be avoided

Embodiment Construction

[0043] image 3 is a side view of the blemish detector. Figure 4 is the front view of the defect detector. Such as image 3 , Figure 4 As shown, the defect detector includes a detection area, an image acquisition unit and a supporting component.

[0044] The detection area includes a columnar hollow cable channel 1 . The cable 6 passes through the cable channel 1 during detection.

[0045]The image acquisition unit includes a light source 2 , a camera 3 and a display 4 . The light source 2 is fixed on the inner wall of the cable channel 1 . The light source 2 can be a point light source or a ring light source. It is cheaper to use a point light, and better to illuminate it with a ring light. In this embodiment, two sets of ring light sources with uniform light emission are used, one set is fixed at the entrance of the cable channel 1, and the other set is fixed at the exit of the cable channel. Figure 5 It is a schematic diagram of the light emission of the ring li...

Abstract

The invention discloses a cable protective jacket surface defect detector and a detection method thereof. The defect detector comprises a detection region, an image acquisition unit and a supporting part, wherein the detection region comprises a columnar hollow cable channel; the image acquisition unit comprises a light source, a plurality of cameras and a display; the light source is fixed on an inner wall of the cable channel; the light source is an annular light source or a dot-shaped light source; the plurality of cameras are uniformly fixed at the periphery of the cable channel at intervals; camera lenses are aligned to the axis direction of the cable channel; the cameras are connected with a gigabit network card in an industrial personal computer through a category 6 enhanced network cable; and the supporting part is arranged under the detection region. The cable protective jacket surface defect detector can be used for detecting the following defects of a cable protective jacket: (1) convex bulges; (2) concave pits and exposed cables, and peeling; (3) non-uniform diameters; and (4) scratches of tubular products and bar materials. The cable protective jacket surface defect detector has a wide detection region and is very practical, and the working efficiency and the product yield of cable protective jacket manufacturers can be effectively improved.

Description

technical field [0001] The invention relates to a cable sheath detection technology, in particular to a cable sheath surface flaw detector and a detection method thereof. Background technique [0002] Surface defects such as bulges, pits, exposed lines, peeling, scratches, and uneven thickness are prone to appear on the surface of the sheath of cables, optical cables, and cable products during production. [0003] Since the sheath production line is the last production process of optical cables, cables, and cables, due to the existing technical characteristics, that is, the production line has a high production speed and a high degree of automation, the optical cable sheath is easily defective during the production process. If it cannot be directly Detecting and eliminating defects during production will directly affect the product quality of optical cables and cables. Later, they will be transferred to customers and cause quality complaints, which will bring great losses to...
