Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and in particular to an automatic cable detection device and a detection method. Background Art

[0002] The main production processes of cables include wire drawing, twisting, insulation extrusion, drying and degassing. In actual production, the cable core may be exposed due to paint leakage. The prevention of this situation is mostly manual visual inspection, which has poor detection effect. After searching, the Chinese invention patent publication number CN112461761A discloses an automatic cable detection device, including a winding piece, a support piece, a detection piece and a marking piece. The winding piece cooperates with the support piece, and the detection piece is fixedly connected to the support piece. The detection piece includes a camera unit, a light source, an ammeter and a detection base. The light source is fixedly connected to the detection base, the detection base is fixedly connected to the support piece, and the ammeter cooperates with the winding piece. The present invention also discloses a detection method, including the automatic cable detection device described above, and also includes the following steps: starting the detection piece and the winding piece; transmitting a signal after detecting an abnormality; starting the camera unit; starting the marking piece. On the basis of the prior art, a detection device is proposed, which utilizes the principle of electrifying a metal brush and utilizes a small LED light electrically connected to the metal brush, thereby effectively improving the practicality of the detection device. A detection method is also proposed, which utilizes the detection method coordinated with the detection device to effectively improve the detection effect. However, when the above-mentioned device is in use, since only a single detection component is provided, and since the cable cannot be rotated during transportation, the device cannot completely detect all positions of the cable, which may result in missed detections. At the same time, the above-mentioned application document uses marking to mark and detect the parts where the paint is missing. Then, since the cable is energized during the detection process, leakage may occur during the detection process, which is dangerous. In addition, since the marking liquid after winding may adhere to other areas of the cable, confusion may occur during subsequent manual repairs. Therefore, how to reasonably solve this problem is what we need to consider. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose an automatic cable detection device and detection method.

[0019] Among them, each of the two rotating cylinders 15 is provided with a conveying assembly, which includes a second rotating gear 29 arranged on the rotating shaft of the upper guide wheel 28, and a one-way bearing is arranged between the second rotating gear 29 and the rotating shaft of the upper guide wheel 28. A transverse groove 26 is arranged on the front side of the transverse plate 17, and a moving block 21 is arranged in the transverse groove 26. The moving block 21 is slidably connected to the inner wall of the transverse groove 26, and the moving block 21 is elastically connected to the rear inner wall of the transverse groove 26 through a first spring 20.

The touch delay switch 3 is connected in series with the corresponding first spring 20 in the loop, and the two touch delay switches 3 are connected in parallel in the loop.

[0020] The present invention also provides a cable automatic detection method, comprising the following steps: S1: First, the cable to be tested is fixed on the conveying roller 4, and then a traction rope is fixed on one end of the cable. The traction rope is passed through two rotating drums 15 in sequence and then fixed on the winding roller 5. Then, the cable is energized, and the driving motor 19 is started at this time to rotate the winding roller 5, so that the cable is driven to move through the traction rope and wound on the winding roller 5 at the same time; S2: During the winding process, the output shaft of the winding roller 5 drives the first rotating rod 7 to rotate through the transmission, thereby driving the corresponding two rotating cylinders 15 to rotate through the two first rotating gears 10, so that the multiple detection sheets 16 are in contact with the side wall of the cable, thereby continuously detecting various parts of the cable, so as to detect whether there are leaking points in the cable; S3: When a cable outlet leakage point is detected, the electromagnet 22 is energized, and the arc block 30 moves forward to stick one end of the electrical tape on the cable. The leakage area is wrapped by the movement of the cable and the rotation of the electrical tape, thereby avoiding the occurrence of unexpected cable outlet accidents during detection and marking the leakage point. S4: When the tape is wrapped to a certain length, the electrical tape can be cut short, and then the delay switch 3 is touched, so that the rack 27 moves back and drives the guide wheel 28 located above to rotate, thereby transporting the electrical tape downward, so as to facilitate wrapping the leakage point next time.

[0021] The functional principle of the present invention can be explained by the following operation mode: first, the cable to be detected is fixed on the conveying roller 4, and then a traction rope is fixed at one end of the cable, and the traction rope is passed through two rotating drums 15 in sequence and then fixed on the winding roller 5, and then the cable is energized, and the driving motor 19 is started at this time, so that the winding roller 5 rotates, thereby driving the cable to move through the traction rope and winding on the winding roller 5 at the same time; During the winding process, the output shaft of the winding roller 5 drives the second rotating rod 18 to rotate through the transmission assembly. Since the two bevel gears are in meshing state, the second rotating rod 18 drives the first rotating rod 7 to rotate, and then drives the two first rotating gears 10 to rotate (since the radius of the rotating wheel on the winding roller 5 is five times the radius of the rotating wheel on the second rotating rod 18, the rotation speed of the second rotating rod 18 and the first rotating rod 7 is faster than the rotation speed of the winding roller 5, so that the cable moves to the right at a slower speed). The two first rotating gears 10 drive the corresponding two rotating cylinders 15 to rotate, so that the corresponding two detection pieces 16 are driven to rotate, so that the lower ends of the multiple detection pieces 16 contact the outer wall of the cable and make a circular motion around the cable, so as to continuously detect various parts of the cable, so as to detect whether there are leaking points in the cable; The detection sheet 16 is provided with two tiny electric contacts, and the two contacts are electrically connected to the two ends of the electromagnet 22 through a wire. When one of the detection sheets 16 contacts the leaking point of the cable, the electromagnet 22 is energized. After the electromagnet 22 is energized, a repulsive force is generated on the slider 25, so that the slider 25 drives the connecting rod and the arc block 30 to move forward, and squeezes the sticky side of the electrical tape onto the cable (because the leaking point is generally very small, the electromagnet 22 is energized for a very short time, so that when the electromagnet 22 is powered off, , under the elastic action of the second spring 24, the slider 25 drives the arc block 30 to move backward, and at this time the electrical tape is already tightly adhered to the cable). Since the electrical tape is installed on the rotating cylinder 15, the electrical tape will rotate with the rotating cylinder 15, and then the electrical tape will be wrapped on the outer wall of the cable. Since the cable is always in a state of moving to the right, a spiral wrapping layer is formed on the cable, thereby wrapping the leaking point. On the one hand, it can avoid dangerous situations during the detection process, and on the other hand, it can better mark the leaking point. When the wrapped area reaches a certain length, the staff can cut the electrical tape below the guide wheel 28 at the bottom, which means that the marking is completed. Then the staff can touch the corresponding touch delay switch 3 to energize the corresponding first spring 20. According to the electromagnetic effect, each coil will generate a differential magnetic field, and the directions of the magnetic fields generated by every two adjacent coils are opposite. Every two adjacent coils generate mutual attraction, so that the first spring 20 contracts and drives the moving block 21 to move backward. At this time, the rack 27 moves backward and then meshes with the second rotating gear 29, so that the second rotating gear 29 drives the guide wheel 28 located above to rotate. Since the surface of the guide wheel 28 is relatively rough, the guide wheel 28 transports the electrical tape downward for easy use next time. After a period of time, the first spring 20 is powered off, so that under the elastic action of the first spring 20, the moving block 21 drives the rack 27 to move back. Due to the setting of the one-way bearing, when the rack 27 moves back, the second rotating gear 29 will not drive the guide wheel 28 to rotate. When the rack 27 moves back to its original position, the rack 27 is not engaged with the second rotating gear 29. At this time, when the electrical tape is subsequently wound, the electrical tape drives the guide wheel 28 and the second rotating gear 29 to rotate, but will not drive the rack 27 to move.

[0022] Compared with the prior art, in the setting of cable leakage points, the detection pieces 16 can be in contact with all parts of the outer wall of the cable through the rotation of multiple detection pieces 16, thereby ensuring the detection effect. At the same time, due to the setting of two detection components, the occurrence of detection omissions can be further reduced. By setting the winding component, when a leakage point is detected, the electrical tape will be wrapped around the cable leakage point, so that no leakage will occur after winding on the winding roller 5, thereby avoiding unexpected situations during the detection process and marking the leakage point.

[0023] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
