Description

Technical Field

[0001] The utility model relates to the technical field of spark testing machines, in particular to a spark testing machine which can automatically imprint marks on defective parts of cables. Background Art

[0002] The spark tester is an online detection device placed on the wire receiving part during the production of wires and cables. Its main function is to use frequency voltage to detect whether the wire products have copper leakage, broken skin, surface impurities, insulation withstand voltage, etc. The spark tester will periodically load the set voltage value onto the insulation wire according to a certain rule, while the conductor part is grounded. In this way, a voltage difference is formed between the conductor and the insulation surface, so that whether the insulation layer is defective can be detected, so that the wire and cable products can be qualified before leaving the factory.

[0003] In the existing technology, the spark tester can detect defects such as breakdown and copper leakage on the outside of the cable, but it cannot accurately determine the exact location of the spark defect. Employees can only manually mark the defective cable when the spark machine alarm sounds based on their feelings. They cannot accurately determine the spark defect area, which can easily lead to the product not being able to 100% determine whether it is a spark defect area, easily causing defective products to flow into the subsequent processes, and there is also the possibility of misjudging the defective area, resulting in cable waste and loss. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a spark testing machine that can automatically imprint marks on defective parts of cables, so as to solve the problem that the existing technology cannot accurately judge the spark defective area, which easily leads to the inability to 100% judge whether the product is a spark defective area, easily causing defective products to flow into the subsequent process, and there is also a technical problem that misjudgment of the defective product area leads to waste and loss of cables.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spark testing machine for automatically imprinting marks on defective parts of cables, comprising a control box, a detection box, and a visual detection module. The detection box is provided with an outlet, the visual detection module is connected to the control circuit in the control box, a connecting ring is fixed to the outside of the outlet of the detection box, a fixing ring is fixed to the side of the connecting ring away from the detection box, at least one screw is passed through the fixing ring, a bevel gear is provided on the rod body of the screw located outside the fixing ring, a connecting ring is fixed inside the bevel gear, at least one limit block is provided on the connecting ring along its radial direction, a limit groove is provided on the rod body of the screw matching the limit block, and a marking head is provided at the end of the screw located inside the fixing ring; the detection box is also provided with a drive assembly connected to the control circuit in the control box, the drive assembly is connected to the bevel gear for driving the screw to rotate relative to the fixing ring when the visual detection module detects sparks in the cable inside the detection box.

[0006] By adopting the above technical solution, the cable passes through the inside of the detection box for inspection, and then passes through the fixed ring for discharge. When the visual inspection module detects that a spark occurs in the cable inside the detection box, it sends a signal. At this time, the control circuit in the control box receives this signal and controls the drive component to drive the bevel gear to rotate. The bevel gear then drives the screw to extend, so that the marking head at the end of the screw squeezes and marks the spark-occurring part of the cable, thereby avoiding the problem of staff having to manually mark the spark-occurring part of the cable, greatly improving the detection quality of the cable, and at the same time improving the overall work efficiency, and the use effect is better.

[0007] Furthermore, at least one lifting frame is slidably connected to the connecting ring, and a power transmission roller is provided at the end of the lifting frame located inside the connecting ring.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] The following describes an embodiment of the present invention based on its overall structure.

[0021] A spark tester that automatically imprints marks on defective parts of cables, such as Figure 1-4As shown, it includes a control box 1, a detection box 2, and a visual detection module. The visual detection module is connected to the control circuit in the control box 1. The detection box 2 is provided with an outlet. The cable 5 is located inside the detection box 2 and one end is discharged from the outlet of the detection box 2. A connecting ring 3 is fixed to the outside of the outlet of the detection box 2, and a fixing ring 4 is fixed to one side of the connecting ring 3. The top and bottom ends of the fixing ring 4 are both threadedly connected to the screw rod 6. The outsides of the two sets of screw rods 6 are both provided with bevel gears 8. The bevel gears 8 are fixed with connecting rings 9 inside. The connecting rings 9 have limit blocks 10 extending into the interior of the screw rod 6 fixed at both ends. The screw rod 6 has limit slots 11 at both ends that cooperate with the limit blocks 10. The ends of the two sets of screw rods 6 are both fixed with marking heads 7 corresponding to the cables 5. When the visual inspection module detects that sparks occur in the cables inside the inspection box 2, it sends a signal to the control circuit in the control box 1. At this time, after receiving the signal, the control circuit in the control box 1 controls the drive assembly to drive the bevel gear 8 to rotate, and the bevel gear 8 then drives the screw 6 to extend, so that the marking heads 7 at the ends of the two sets of screws 6 squeeze and mark the sparking parts of the cable 5, thereby avoiding the problem of the staff having to manually mark the sparking parts of the cable 5, greatly improving the inspection quality of the cable 5, and at the same time improving the overall work efficiency, and the use effect is better.

[0022] In addition, the top and bottom ends of the connecting ring 3 are slidably connected to lifting frames 16, and the ends of both lifting frames 16 are equipped with power transmission rollers 17 that cooperate with the cable 5. The ends of the two sets of screws 6 are fixed to fixed plates 12, and a tooth plate 19 is fixed to one side of the fixed plate 12. The top and bottom of one side of the connecting ring 3 are rotatably connected to lifting gears 18 that mesh with the tooth plate 19, and the top side of the lifting frames 16 is provided with a tooth groove that meshes with the lifting gear 18. When the marking head 7 begins to mark the sparking part of the cable 5, the two sets of power transmission rollers 17 simultaneously disengage from the cable 5, that is, they no longer transport the cable 5. This makes the marking process of the marking head 7 on the cable 5 more stable and avoids deviation and interference.

[0023] See also Figure 2 The outside of the fixed ring 4 is movably connected with a bevel gear ring 13 that meshes with the two sets of bevel gears 8. A motor 14 is installed at one end of the connecting ring 3, and a driving gear 15 that meshes with the bevel gear ring 13 is fixed to the output end of the motor 14. The outside of the bevel gear ring 13 is provided with an external tooth groove that meshes with the drive gear 15, and the inside of the bevel gear ring 13 is provided with an internal tooth groove that meshes with the bevel gear 8. The utility model is provided with the above structure, in which the motor 14 plays an overall driving role, so that the two sets of marking heads 7 can simultaneously perform synchronous extrusion marking on the bottom and top of the cable 5.

[0024] See also Figure 2 and Figure 4The connecting ring 3 and the two sets of lifting gears 18 are movably connected through the support frame 20, and the lifting gears 18 and the support frame 20 are rotatably connected through bearings. By setting the above structure, the utility model plays a role of supporting the lifting gears 18.

[0025] The working principle of the utility model is as follows: when in use, the power is turned on, the cable 5 passes through the inside of the detection box 2 for detection, and then passes through the fixing ring 4 for discharge; the conductive core or shield of the cable 5 is grounded, and the cable 5 passes through the high-voltage electrode inside the detection box 2 at a certain speed, so that the insulation layer or sheath layer is subjected to high-voltage test. The high voltage will generate an electric field between the electrodes. When the electric field strength exceeds the insulation strength of the tested material, the electric field will induce electric shock breakdown and form spark discharge. Bright sparks will be generated during spark discharge. The characteristics of the sparks, such as shape, color, length and frequency, will be affected by the insulation performance of the material. According to the observed spark characteristics, It is determined whether the electrical insulation performance of the tested material is qualified, so that it is identified and detected by the visual inspection module, and then a signal is sent to the control circuit in the control box 1. The control circuit in the control box 1 controls the motor 14 to work according to the signal. The motor 14 drives the bevel gear 8 to rotate through the driving gear 15, so that the bevel gear 8 drives the screw 6 to extend, so that the marking heads 7 at the ends of the two sets of screws 6 squeeze and mark the sparking parts of the cable 5, thereby avoiding the problem that the staff needs to manually mark the sparking parts of the cable 5, greatly improving the detection quality of the cable 5, and at the same time improving the overall work efficiency, and the use effect is better.

[0026] Furthermore, when the two sets of bevel gears 8 rotate, the screw 6 is driven to rotate through the connecting ring 9 and the limit block 10. Since the screw 6 and the fixing ring 4 are threadedly connected, the screw 6 rotates and moves radially relative to the fixing ring 4, so that the marking head 7 can extrude and mark the surface of the cable 5.

[0027] Furthermore, a limiting groove 11 is provided inside the screw 6 to cooperate with the limiting block 10 , so that when the screw 6 rotates and extends, the rotation of the bevel gear 8 is not affected.

[0028] Furthermore, when the screw 6 moves relative to the inside of the fixed ring 4, the tooth plate 19 is driven to move through the fixed plate 12. Since the tooth plate 19 and the lifting frame 16 are engaged through the lifting gear 18, when the tooth plate 19 descends, the lifting frame 16 drives the power transmission roller 17 to rise. In other words, at this time, the power transmission roller 17 is disengaged from the transmission of the cable 5.

[0029] In summary, when the marking head 7 starts to mark the sparking part of the cable 5, the two sets of power transmission rollers 17 are separated from the cable 5 at the same time, that is, the cable 5 is no longer transported at this time, which makes the marking process of the marking head 7 on the cable 5 more stable and avoids offset and interference.

The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
