Description

Technical Field

[0001] The utility model relates to the field of wire harness preparation, in particular to a metal wire harness braiding breakage detection device. Background Art

[0002] The wire core of a wire harness is usually formed by twisting multiple metal wires. During processing, multiple metal wires are usually led out from the wire bundle separately, and then twisted by cable twisting equipment to form a finished wire core. If any metal wire breaks during this process, it will cause quality defects in the finished wire core, and in severe cases, the finished product will be scrapped. Therefore, it is necessary to monitor the metal wires.

[0003] At present, a Chinese invention patent application with publication number CN107068299A discloses a wire break detection device for cable twisting equipment and a method for wire break detection and judgment, including a first detection unit, a second detection unit, a microcontroller and a sensing module. The wire break detection device does not need to set parameters and can obtain the actual number of single wires of the twisted wire by itself. When the number of single wires decreases, it is determined to be a wire break.

[0004] A previous wire breakage detection device and wire breakage detection and judgment method for cable twisting equipment disclosed a scheme for monitoring wire breakage of metal wires. However, when in use, it is necessary to compare the number of single wires of the twisted wire detected by the second detection unit in each week during the multiple rotations of the second turntable, and determine the wire breakage after obtaining the difference value. With this scheme, after the wire breakage result is obtained, the equipment continues to run for a period of time, and the wire breakage result cannot be fed back in time. Utility Model Content

[0005] The utility model aims to provide a metal wire harness braided wire breakage detection device, which has the advantage of being able to provide timely feedback when the metal wire breaks.

[0006] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides the following technical solutions: a metal wire harness braided wire breakage detection device, comprising:

[0007] A support frame mounted on the cable twisting device, wherein a plurality of wire rollers loaded with metal wires are rotatably connected to the support frame;

[0008] A plurality of detection members arranged one by one corresponding to the wire rollers, used to monitor the rotation of the wire rollers and trigger a sensing signal in real time when the wire rollers rotate; and

[0009] The controller is respectively connected with each of the detection components by electrical signals, receives the induction signals sent by the detection components, and judges that the metal wire is broken when no induction signal from any detection component is received, thereby controlling the device to stop running.

[0010] Through the above technical scheme, the cable twisting equipment will draw the metal wires from the wire roller when twisting the metal wires into a wire core, thereby pulling the wire roller to rotate. When the wire roller rotates, the detection element triggers the sensing signal in real time and sends the sensing signal to the controller, which receives the electrical signal and monitors the signal sending of each detection element. Once the detection element corresponding to a wire roller no longer sends an electrical signal, it indicates that the metal wire led out of the wire roller is no longer connected to the cable twisting equipment, which means that the metal wire is broken. This scheme monitors the rotation status of each wire roller in real time, and can promptly feedback to the controller when the metal wire is broken, so that the equipment can be stopped in time for easy maintenance.

[0011] In an embodiment of the present invention, the detection element is configured as an encoder, a photoelectric sensor or a pressure sensor.

[0012] Through the above technical solution, the encoder, photoelectric sensor or press sensor triggers the sensing signal and sends it to the controller.

[0013] In one embodiment of the utility model, it also includes a plurality of turntables rotatably connected to the support frame, and a fixing assembly for mounting a wire roller so that the turntable and the wire roller are relatively fixed is provided on the turntable, and the detection member detects the rotation of the turntable.

[0014] Through the above technical solution, when replacing the metal wire, it is only necessary to remove the wire roller from the turntable, and then fix the new wire roller on the turntable through the fixing component, which makes it convenient to replace the wire roller.

[0015] In one embodiment of the present invention, the fixing assembly includes:

[0016] A locking screw is fixed to the turntable, and the line roller is sleeved on the locking screw; and a locking nut is threadedly connected to the locking screw, and the locking nut and the turntable apply extrusion force to the line roller and use friction force to fix the line roller and the turntable relatively.

[0017] Through the above technical solution, the wire roller is sleeved on the locking screw, and then the locking nut is tightened. The locking nut and the turntable together squeeze and fix the wire roller, and the fixation is convenient and quick.

[0018] As described above, the metal wire harness braided wire breakage detection device of the present invention has the following beneficial effects:

[0019] When twisting the metal wires into a wire core, the cable twisting equipment will draw the metal wires from the wire roller, thereby driving the wire roller to rotate. When the wire roller rotates, the detection element triggers the sensing signal in real time and sends the sensing signal to the controller. The controller receives the electrical signal and monitors the signal sending of each detection element. Once the detection element corresponding to a certain wire roller no longer sends an electrical signal, it indicates that the metal wire led out of the wire roller is no longer connected to the cable twisting equipment, which means that the metal wire is broken. This solution monitors the rotation status of each wire roller in real time, and can promptly feedback to the controller when the metal wire is broken, so that the equipment can be stopped in time for easy maintenance.

It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0024] Example 1

[0025] See also Figure 1 The utility model provides a metal wire harness braided wire break detection device, comprising:

[0026] A support frame 1 is installed on the cable twisting device by screws, and the upper surface of the support frame 1 is set as a horizontal plane. A plurality of turntables 4 are set on the upper surface of the support frame 1. The turntables 4 are rotatably connected to the support frame 1 through a rotating shaft. The number of turntables 4 is the same as the number of metal wires required to be used.

[0027] See also Figure 1, also includes a wire roller 2 containing a metal wire and a fixing component 5 for fixing the wire roller 2 on a turntable 4. The number of wire rollers 2 and the number of fixing components 5 are the same as the number of turntables 4. The wire roller 2 includes a cylindrical body and baffles fixed at both ends of the cylinder. The metal wire is wound around the cylinder. The metal wire is drawn out from the wire roller 2 and enters the cable twisting equipment. The fixing component 5 includes: a locking screw 6 welded and fixed to the turntable 4, and the wire roller 2 is sleeved on the locking screw 6; and a locking nut 7 threadedly connected to the locking screw 6. After the locking nut 7 is tightened, it applies an extrusion force to the wire roller 2 with the turntable 4, and uses friction to relatively fix the wire roller 2 and the turntable 4, so that the metal wire is pulled by the cable twisting equipment and the wire roller 2 drives the turntable 4 to rotate.

[0028] See also Figure 1 , and also includes a plurality of detection members 3 which are arranged one by one corresponding to the line rollers 2, and are used to monitor the rotation of the line rollers 2 and trigger induction signals in real time when the line rollers 2 rotate. In this embodiment, the detection member 3 is arranged as an encoder, and the encoder monitors the rotation of the turntable 4 and sends a signal in real time when the turntable 4 rotates.

[0029] See also Figure 1 , and also includes a controller, which is electrically connected to each detection component 3, receives the induction signal sent by the detection component 3, and determines that the metal wire is broken when no induction signal from any detection component 3 is received, and then controls the device to stop running.

[0030] When twisting the metal wires into a wire core, the cable twisting device of the utility model will draw the metal wires from the wire roller 2, thereby pulling the wire roller 2 to rotate. When the wire roller 2 rotates, the detection component 3 triggers the sensing signal in real time and sends the sensing signal to the controller, which controls the receiving electrical signal and monitors the signal sending status of each detection component 3. Once the detection component 3 corresponding to a certain wire roller 2 no longer sends an electrical signal, it indicates that the metal wire led out of the wire roller 2 is no longer connected to the cable twisting device, which means that the metal wire is broken. This solution monitors the rotation status of each wire roller 2 in real time, and can promptly feedback to the controller when the metal wire is broken, so that the equipment can be stopped in time for easy maintenance.
