The seventh embodiment:
different from the sixth specific embodiment, in the winding type cable skin detection device of the present embodiment, the speed measurement system 8 is installed outside the carrying box 2, and is located between the auxiliary bracket 9 and the detection system 7, so as to measure the movement speed of the passing cable.
The working principle is as follows:
before the wound cable skin detection device is used, a cable to be detected is wound on a winding wheel 3g, and the winding wheel 3g of the cable to be detected is mounted on a winding system 3 at the rear end after winding, wherein the winding wheel 3g is called as a winding wheel 3g1 to be detected; an empty reel 3g is then mounted on the front end winding system 3, referred to herein as the measured reel 3g 2.
One end of the tested cable 10 is taken out from the reel 3g1 to be tested and is penetrated into the detection system 7 through the auxiliary wheel 9b of the auxiliary bracket 9 close to the rear end; the cable 10 passes through the U-shaped notch of the detection end cover 7e on one side into the detection box 7d, then passes through the U-shaped notch of the detection end cover 7e on the other side, passes through the auxiliary wheel 9b of the auxiliary bracket 9 close to the front end, bypasses 3 wire guide wheels 6g of the wire guide system 6, and then is fixed on the detected wire winding wheel 3g 2. The two auxiliary supports 9 are adjusted to proper positions, so that the cables 10 just penetrate into and penetrate out of the U-shaped notches of the detection end covers 7e at the two ends, and the smooth operation of the cables 10 in the detection process is guaranteed.
The operator performs manual inspection of the cable 10 that has been drawn off from the reel under test 3g1, because the cable 10 that has passed through the inspection system 7 during the threading phase can no longer be inspected by the inspection system 7, by which manual inspection quality problems in the skin of the section of cable 10 can be avoided.
Relevant detection parameters such as the respective attributes of the front and rear reel rotation speeds and respective threshold values for detection judgment are set according to the color and diameter of the cable 10, and then the start button of the control buttons 5 is pressed to start the detection process of the cable 10.
When the detected cable 10 passes through the detection box 7d, the 3 detection cameras 7c which are sequentially arranged at intervals of 120 degrees in the circumferential direction can acquire images of the skin of the cable 10 from 3 directions, the acquired data are transmitted to the control unit in the touch system 4, and whether the skin is defective or not is judged through an algorithm program.
The speed measuring system 8 detects the running speed of the cable 10, the cable 10 runs under the traction of the reel 3g2 with the front end tested and the matching rotation of the reel 3g1 with the rear end tested, so that the running speed of the tested cable 10 needs to be measured in real time, the rotating speed of the corresponding lead motor 6c is adjusted, the speeds of the front reel and the rear reel are matched, and the situation that the testing effect is influenced by the fact that the tested cable 10 is too loose in the testing system 7 or the cable is broken due to the fact that the tested cable is too tight is avoided.
The lead system 6 is used for ensuring that the cable 10 is uniformly wound on the tested reel 3g2, the lead motor 6c drives the lead sliding block 6h to move through a lead screw nut pair formed by the lead screw shaft 6i and the lead screw nut 6m, the positive and negative rotation of the lead motor 6c can be converted into the reciprocating motion of the lead sliding block 6h, and then the cable 10 is uniformly wound on the tested reel 3g2, so that the winding quality is ensured.
If the detection system 7 finds that the outer skin of the cable 10 has quality problems such as incomplete damage and the like in the detection process, the control system of the touch system 4 gives out sound and light alarms, stops the rotation of the reel 3g1 to be detected and the reel 3g2 to be detected, and waits for the detection and treatment of an operator. When the problem is eliminated, the operator presses the start button of the control buttons 5 again to continue the detection process of the cable 10.
When the speed measured by the speed measuring system 8 is zero, the detection of the cable 10 of the reel 3g1 to be detected is judged to be finished, the control unit in the touch system 4 can give out an audible and visual alarm to prompt an operator to press a stop button in the control buttons 5, and then the new reel 3g1 to be detected and the tested reel 3g2 are replaced so as to carry out the cable detection of a new round. If the wound cable skin detection device suddenly fails in the working process, an operator can press an emergency stop button in the control buttons 5 to prevent further damage to the equipment or the detected cable 10.
