Cable surface defect detection and classification device

Abstract

According to the cable surface defect detection and classification device provided by the invention, in the process, the cable is supported in the annular limiting groove of each limiting wheel. And the cable limiting unit can adjust the distance between limiting wheels which are arranged up and down, so that the cable surface defect detection and classification device can adapt to cables of different sizes, and the application range of the cable surface defect detection and classification device is widened. The two industrial cameras are used for comprehensively and finely shooting the cable passing through the detection mechanism, and the control mechanism is used for analyzing pictures transmitted by the two industrial cameras. When the surface layer of the cable goes wrong, the control mechanism controls the two cable bearing mechanisms to convey the faulted part of the cable to the vicinity of the cable folding and labeling machine, and the cable folding and labeling machine labels the vicinity of the faulted part of the cable. On one hand, the surface of the bundled to-be-detected cables is proved to have problems, and on the other hand, the parts with the problems are marked, so that later repair treatment is facilitated.

Pull handles 164 are provided on both sides of each end of the sliding carrier plate 162. The sliding carrier 162 is used to carry the cable reel 500. When the cable reel 500 is to be installed on the cable carrying mechanism 100, the cable reel 500 is first placed on the sliding carrier 162, and then the sliding carrier 162 is pushed to move along the slideway 102 by pulling the handle 164, so that the driving block 144 is inserted into the first driving groove 501 at one end of the cable reel 500, and the driving cylinder 152 drives the rotating block 156 to be inserted into the second driving groove 502 at the other end of the cable reel 500 through the driving slider 153, the rotating bearing 154, and the rotating rod 155, thereby completing the installation of the cable reel 500. In this way, the receiving assembly 160 further facilitates the installation and removal of the bundled cable reels 500 to be tested or the empty cable reels 500.

[0030] In order to improve the working stability of the receiving assembly 160, the cable bearing mechanism 100 further includes a height adjustment assembly 170. Two push plates 165 are arranged on the sliding carrier plate 162. A sliding groove 103 is provided on the top of the bearing platform 110. A sliding groove 104 is provided on the side wall of the bearing platform 110. One end of the sliding groove 103 is connected to the middle area of ​​the sliding groove 104.

The sliding column 175 is adapted to the sliding groove 103, one end of the sliding column 175 is inserted in the sliding groove 103 and is slidably connected to the bearing platform 110, and the other end of the sliding column 175 is connected to the middle area of ​​the bottom of the receiving block 161. The end of the sliding column 175 inserted in the sliding groove 103 is provided with a passive inclined surface, and the end of the sliding rod 174 inserted in the sliding groove 104 is provided with a driving inclined surface, and the passive inclined surface can slide and abut against the driving inclined surface. During operation, the cable reel 500 is first placed on the sliding carrier 162, so that each push plate 165 abuts against a wheel on the cable reel 500, and then the sliding carrier 162 is pushed to move along the slideway 102 by pulling the handle 164, so that the driving block 144 is inserted into the first driving groove 501 at one end of the cable reel 500, and the driving cylinder 152 drives the rotating block 156 to insert into the second driving groove 502 at the other end of the cable reel 500 through the driving slider 153, the rotating bearing 154, and the rotating rod 155, thereby completing the installation of the cable reel 500. After installation, the rotating motor 172 drives the sliding rod 174 to move backward along the sliding groove 104 through the rotating gear 173 and the linear gear 176. During the backward movement of the sliding rod 174, the sliding column 175 is driven to move downward along the sliding groove 103 to prevent the two push plates 165 from affecting the rotation of the cable reel 500. In this way, the working stability of the receiving assembly 160 is improved.
