Wire presence and breakage detection mechanism

Abstract

This utility model relates to the field of cable manufacturing technology, specifically disclosing a cable presence and damage detection mechanism. The mechanism involves passing the cable through a threading hole. When the left and right clamps close and tighten, the pressure rollers on the left and right clamps compress the cable. Pulling the cable through these rollers allows it to pass between them. If the cable insulation is damaged, the pressure rollers transmit an electrical signal through the damaged area, thus detecting cable damage. If no cable is found between the pressure rollers after detection, the clamping action causes the pressure rollers to contact each other, transmitting an electrical signal and indicating that the cable detection is complete.

Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to a cable presence and damage detection mechanism. Background Technology

[0002] During the production and unloading process, cables need to be inspected after production. The outside of the cable is usually wrapped with an insulation layer. Before production and unloading, the insulation layer of the newly produced cable needs to be inspected for damage to prevent electrical accidents caused by cables with damaged insulation layers in actual use. The current cable insulation layer damage inspection generally requires workers to pull the cable out from the cable winding roller while checking whether the cable insulation layer is damaged. The entire cable insulation layer damage inspection requires a large amount of manpower and the detection efficiency is also poor.

[0003] The technical problem to be solved by this application is: to design an efficient and automatic detection mechanism for the presence, absence, and damage of lines. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a highly efficient and automatic detection mechanism for the presence, absence and damage of wires.

[0005] The technical solution adopted by this utility model is as follows: a wire presence and damage detection mechanism, including a left clamp and a right clamp, a wire hole for wires to pass through is provided between the left clamp and the right clamp, the left clamp and the right clamp are respectively provided with corresponding wire pressing wheels, and carbon brushes that contact the wire pressing wheels for transmitting electrical signals are respectively provided inside the left clamp and the right clamp.

[0006] In some embodiments, the left gripper is provided with a left U-shaped fork, and the right gripper is provided with a right U-shaped fork, with the left and right U-shaped forks being arranged alternately.

[0007] In some embodiments, the left U-shaped fork has a left central groove and the right U-shaped fork has a right central groove. After the left U-shaped fork and the right U-shaped fork overlap, a threading hole is formed between the left central groove and the right central groove.

[0008] In some embodiments, both the left and right grippers are provided with mounting grooves, and the pressing wheels on the left and right grippers are respectively installed in the mounting grooves of the left and right grippers. The bottom of the pressing wheel on the left gripper is rotatably connected to the left gripper, and the bottom of the pressing wheel on the right gripper is rotatably connected to the right gripper.

[0009] In some embodiments, the left and right grippers are provided with connecting baffles on the side away from the pressure roller, and a connecting strip is provided between the carbon brush and the connecting baffles.

[0010] In some embodiments, a spring is provided between the carbon brush and the connecting baffle, the spring being sleeved on the connecting strip and in a compressed state.

[0011] This invention has the following technical effects: The left and right jaws are each equipped with corresponding pressure rollers, and a through-hole for cable passage is provided between the left and right jaws. The interiors of the left and right jaws each have carbon brushes that contact the pressure rollers for transmitting electrical signals. When the cable passes through the through-hole and the left and right jaws close tightly, the pressure rollers on the left and right jaws compress the cable. Pulling the cable through the pressure rollers causes it to pass between them. If the cable insulation is damaged, the two pressure rollers will transmit an electrical signal through the damaged area, thus detecting whether the cable is damaged. If the cable inspection is complete and there is no cable between the two pressure rollers, the pressure rollers of the left and right jaws will contact each other due to the clamping action, also transmitting an electrical signal, indicating that the cable inspection is complete.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-2This utility model provides a technical solution: a cable presence / absence and damage detection mechanism, including a left gripper 1 and a right gripper 2. A cable-passing hole 3 is provided between the left gripper 1 and the right gripper 2. The left gripper 1 and the right gripper 2 are respectively equipped with corresponding pressure rollers 4. When cable damage detection is required, the cable is passed through the cable-passing hole 3 and between the two pressure rollers 4, causing the left gripper 1 and the right gripper 2 to close and clamp together. At this time, the pressure rollers 4 on the left gripper 1 and the right gripper 2 clamp the cable. When the cable is pulled out, because the cable is clamped by the pressure rollers 4 on both sides, as the cable is pulled out, the cable drives the pressure rollers 4 to rotate. If the cable insulation layer is damaged... If the cable is damaged, the damaged layer will act as a medium to transmit electrical signals between the two pressure rollers 4, indicating that the cable insulation layer is damaged. In order to enable the transmission of electrical signals between the two pressure rollers 4, the left jaw 1 and the right jaw 2 are respectively equipped with carbon brushes 5 that contact the pressure rollers 4 for transmitting electrical signals. The carbon brushes 5 of the left jaw 1 and the right jaw 2 are connected to the external electrical testing system. If the entire roll of cable is pulled out, there is no cable between the two pressure rollers 4. However, as the left jaw 1 and the right jaw 2 close and clamp each other, the pressure rollers 4 on the left jaw 1 and the right jaw 2 will contact each other to achieve the transmission of electrical signals, indicating that the cable test is complete and there is no cable between the two pressure rollers 4.

[0016] The left gripper 1 is provided with a left U-shaped fork 10, and the right gripper 2 is provided with a right U-shaped fork 20. The left U-shaped fork 10 and the right U-shaped fork 20 are staggered so that the left gripper 1 and the right gripper 2 can close and clamp each other. The left U-shaped fork 10 is provided with a left central groove 11, and the right U-shaped fork 20 is provided with a right central groove 21. When the left gripper 1 and the right gripper 2 close and clamp each other, the left U-shaped fork 10 and the right U-shaped fork 20 can overlap each other so that a wire hole 3 is formed between the left central groove 11 and the right central groove 21.

[0017] In order to enable the two pressure rollers 4 to rotate when the cable is clamped by the pressure rollers 4 and the cable is pulled out, the left clamp 1 and the right clamp 2 are also provided with mounting grooves 6. The pressure rollers 4 on the left clamp 1 and the right clamp 2 are respectively installed in the mounting grooves 6 of the left clamp 1 and the right clamp 2. The bottom of the pressure roller 4 on the left clamp 1 is rotatably connected to the left clamp 1, and the bottom of the pressure roller 4 on the right clamp 2 is rotatably connected to the right clamp 2.

[0018] In order to enable the carbon brush 5 to contact the pressure roller 4, a connecting baffle 7 is provided on the side of the left clamp 1 and the right clamp 2 away from the pressure roller 4. A connecting strip 8 is provided between the carbon brush 5 and the connecting baffle 7. A spring 9 is provided between the carbon brush 5 and the connecting baffle 7. The spring 9 is sleeved on the connecting strip 8 and is in a compressed state. The compressed spring 9, due to its own rebound force, pushes the carbon brush 5 to contact the pressure roller 4, thereby facilitating the transmission of electrical signals.

[0019] The working principle of this utility model is as follows: Corresponding wire-pressing rollers 4 are provided on the left jaw 1 and right jaw 2, and a wire-passing hole 3 is provided between the left jaw 1 and right jaw 2 for cable passage. Carbon brushes 5, which contact the wire-pressing rollers 4, are provided inside the left jaw 1 and right jaw 2 to transmit electrical signals. When the cable passes through the wire-passing hole 3 and the left jaw 1 and right jaw 2 are closed and clamped together, the wire-pressing rollers 4 on the left jaw 1 and right jaw 2 will squeeze the cable. Pulling the cable allows it to pass between the two wire-pressing rollers 4. If the cable insulation is damaged, the two wire-pressing rollers 4 will transmit electrical signals through the damaged area, thus detecting whether the cable is damaged. If the cable detection is complete and there is no cable between the two wire-pressing rollers 4, the clamping of the left jaw 1 and right jaw 2 will cause the wire-pressing rollers 4 to contact each other, also transmitting electrical signals, indicating that the cable detection is complete.

[0020] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
