The wiring harness is an important part of the vehicle electrical system and is responsible for power transmission and signal transmission. It involves the power supply and control of multiple components such as the engine, headlights, air conditioning, electric windows, and seat adjustment. Therefore, its quality directly affects the performance and safety of the car.

[0017] A method for detecting an automobile wiring harness comprises the following steps:

[0018] S1: First, place the wiring harness inside the clamping groove so that the plug-in ends of the wiring harness are located outside the two moving blocks. By controlling the detection motor to start, the two moving blocks are driven to move toward the direction of socket 1 until the plug-in ends at both ends of the wiring harness are plugged into the inside of the two sockets. Then, the wiring harness can be powered on and tested by starting the power box.

[0019] S2: When the two moving blocks move toward the two sockets, the ductility of the wiring harness can be stretched and the strength of the plug ends at both ends of the wiring harness can be tested. This allows the wiring harness to be stretched and the strength of the plug ends to be tested simultaneously during power-on testing, and the test results can be displayed on the display.

[0020] S3: When an abnormality occurs in the wiring harness during power-on detection, the temperature of the wiring harness will continue to rise. When the temperature reaches the threshold of the temperature sensor, the power to magnet block 1 is cut off. The spring loses the adsorption of magnet block 1 and rebounds toward connecting plate 2, driving the support column and connecting plate 2 to generate a force of movement, separating socket 2 from the interior of socket 1, and automatically cutting off the power to the wiring harness, thereby ensuring the safety of the test;

[0021] S4: The temperature of the wiring harness is sensed by the temperature sensor. When the temperature of the wiring harness reaches the threshold set by the temperature sensor, the two electromagnets are controlled to be de-energized through the connecting plate 2. The two wedge plates can quickly move toward the mounting frame under the action of the spring, driving the movable plate 2 to move toward the wiring harness. The puncture needle is inserted into the interior of the wiring harness and contacts the conductive wire inside the wiring harness, so that the residual electricity inside the wiring harness is transferred through the puncture needle and the conductive wire to the interior of the conductive seat, and finally discharged outward through the conductive seat, ensuring that the residual electricity inside the wiring harness can be released after the wiring harness is powered off.

[0022] The present invention provides an automobile wiring harness detection device, which has the following beneficial effects:

[0023] 1. By setting up a test component, during the process of detecting the start-up of the motor, it can drive gear one to rotate, drive the threaded rods at both ends of the connecting shaft to rotate, and the threaded directions of the threaded rods at both ends of gear two are opposite, so that the two moving blocks move toward the direction of socket one until the plug-in ends at both ends of the wiring harness are plugged into the inside of the two sockets. The wiring harness is powered on and tested by starting the power box. In the process of the two moving blocks moving toward the two sockets, the ductility of the wiring harness can also be stretched and tested. At the same time, the strength of the plug-in ends at both ends of the wiring harness can also be tested, thereby achieving the purpose of synchronously performing stretching and plug-in end strength tests on the wiring harness during the power-on detection process, and the test results can be displayed on the display, replacing the existing single testing method, thereby greatly increasing the overall practicality of the device.

[0024] 2. By setting up a sensor drive component, when an abnormality occurs in the wiring harness during the power-on detection process, that is, when an abnormality occurs after the wiring harness is powered on, the temperature of the wiring harness will continue to rise. When the temperature reaches the threshold of the temperature sensor, the power to magnet block one can be cut off. When magnet block one is powered off, the shrapnel loses the adsorption of magnet block one and can rebound toward the direction of connecting plate two, thereby driving the anti-pillar and connecting plate two to generate a force for movement, and then socket two can be separated from the inside of socket one. That is, when an abnormality occurs during the power-on test, the wiring harness can be automatically powered off, thereby ensuring the safety of the test.

[0025] 3. By setting up a cleaning component, the bottom surface of the movable plate 1 contacts and presses the touch switch, which can control the start of the discharge motor, drive the wire feed trough to rotate one circle inside the wire storage box, and can transfer the wire harness inside the placement trough to the inside of the wire bucket, and then be transported by the wire bucket to the outer surface of the guide plate and slide to the C-shaped frame. The rotation of the discharge motor is controlled by the touch switch to achieve the purpose of automatic unloading. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0040] Reference Figures 1-11 The present invention provides a technical solution: an automobile wiring harness detection device, comprising a main box 1, a top plate 2 is fixedly mounted on the top surface of the main box 1, detection frames 3 are fixedly mounted on both ends of the top surface of the top plate 2, a socket 1 4 is fixedly mounted inside the detection frame 3, a power box 5 is provided on one side of the detection frame 3, a connecting line 6 is fixedly connected to one side of the power box 5, a socket 2 7 is fixedly mounted on one end of the connecting line 6, the socket 2 7 is plugged into the inside of the socket 1 4, a detection table 8 is fixedly mounted between the two sockets 1 4, a detection mechanism 9 is provided on the inner side of the detection table 8, a wiring harness 10 is placed inside the detection mechanism 9, a material discharge component 12 is provided on the top surface of the main box 1, and a display 13 is provided on one side of the material discharge component 12;

[0041] When testing the wiring harness 10, it is only necessary to place the wiring harness 10 to be tested uniformly inside the discharge component 12, and then the wiring harness 10 can be discharged through the discharge component 12 for visual inspection, and the wiring harness 10 is cleaned by the cleaning component 14. Dust remaining on the plug connector of the wiring harness 10 will affect subsequent tests. During the test process, the wiring harness 10 can be subjected to multiple tests such as power-on test and stretch test, and the test results and test data are displayed in real time through the display 13, thereby realizing the testing operation of the wiring harness 10.

[0042] The detection mechanism 9 includes a test assembly and a sensor drive assembly. The test assembly includes a through slot 901. An H-shaped frame 902 is fixedly installed inside the through slot 901. Both ends of the H-shaped frame 902 are fixedly installed with a slide frame 903. The slide frame 903 is movably connected to a T-shaped frame 904 inside. The top of the T-shaped frame 904 is fixedly installed with a moving block 905. The setting of the test assembly is used to test the wiring harness 10.

[0043] A detection motor 907 is fixedly installed inside the main case 1, and a gear 1 908 is fixedly installed on the output end of the detection motor 907. A connecting plate 1 913 is fixedly installed on the bottom surface of the T-frame 904, and a socket frame 912 is fixedly installed on the bottom surface of the connecting plate 1 913. The interior of the socket frame 912 is threadedly sleeved with a threaded rod 911, and a connecting shaft 909 is fixedly connected between the two threaded rods 911. Gear 2 910 is fixedly installed on the outer surface of the connecting shaft 909, and gear 2 910 and gear 1 908 are meshed with each other. A clamping groove 906 is provided on the top surface of the slide frame 903, and the two ends of the wiring harness 10 are respectively clamped in the inside of the two clamping grooves 906. A C-frame 917 is fixedly installed on the side surface of the movable plate 1 921, and a horizontal plate 918 is fixedly installed on one end of the C-frame 917. The temperature sensor 920 is fixedly installed on the top surface of the horizontal plate 918, and anti-slip plates 919 are fixedly installed at both ends of the horizontal plate 918.

[0044] During operation, when testing the wiring harness 10, first place the wiring harness 10 inside the clamping groove 906 so that the plug-in ends of the wiring harness 10 are respectively located outside the two moving blocks 905, and then control the detection motor 907 to start. During the start-up of the detection motor 907, it can drive gear 1 908 to rotate. During the rotation of gear 1 908, it can drive the connecting shaft 909 to rotate under the action of gear 2 910, thereby driving the threaded rods 911 at both ends of the connecting shaft 909 to rotate, and the threaded rods 911 at both ends of gear 2 910 have opposite thread directions. Therefore, when the detection motor 907 rotates, it can drive the two socket frames 912 toward each other under the action of the thread. The two movable blocks 905 move in opposite directions, thereby driving the two movable blocks 905 to move toward the socket 4 until the plug-in ends at both ends of the wiring harness 10 are plugged into the inside of the two sockets 4. The wiring harness 10 can be powered on by starting the power box 5. Moreover, in the process of the two movable blocks 905 moving toward the two sockets 4, the ductility of the wiring harness 10 can be stretched and tested, and the strength of the plug-in ends at both ends of the wiring harness 10 can be tested. This realizes the simultaneous tensile and plug-in end strength tests of the wiring harness 10 during the power-on detection process, and the test results can be displayed on the display 13, replacing the existing single testing method, thereby greatly increasing the overall practicality of the device.

[0045] Moreover, during the test, that is, when the two movable blocks 905 move toward both ends, the test data is the data after the wire harness 10 is stretched, that is, the power-on test is performed after the wire harness 10 is stretched, which can better simulate the harsh environment of the wire harness 10 during actual use and improve the test strength of the wire harness 10, that is, it is helpful to improve the quality of the wire harness 10 after the test, thereby improving the safety of the wire harness 10 after it is put into use.

[0046] The above-mentioned testing process is a sampling test, that is, a plurality of representative wiring harnesses 10 are selected for testing, and the tested wiring harnesses 10 are individually numbered to represent a batch of wiring harnesses 10 .

[0047] By setting the C-shaped frame 917, when the two connecting plates 1 913 move in opposite directions, the movable plate 1 921 and the movable plate 2 924 can be driven downward by the action of the inclined plate 916, thereby driving the C-shaped frame 917 installed on one side surface of the movable plate 1 921 to move downward synchronously, and then driving the anti-slip plates 919 at both ends of the C-shaped frame 917 to move downward, so that the anti-slip plates 919 are clamped into the inside of the clamping groove 906, limiting the wiring harness 10, thereby ensuring stability during subsequent stretching and power-on testing. This ensures that the wiring harness 10 will not be detached from the inside of the clamping groove 906 during the test, and when the C-frame 917 moves downward, it can also synchronously drive the temperature sensor 920 to move downward. When the plug-in end of the wiring harness 10 is plugged into the inside of the socket 4, the sensing end of the temperature sensor 920 fits into the outer surface of the wiring harness 10, and the temperature of the wiring harness 10 during the power-on test can be monitored in real time to ensure the safety of the wiring harness 10 during the power-on test, and the monitored real-time temperature will be displayed on the display 13.

[0048] The sensing and driving assembly includes a temperature sensor 920 and a movable plate 1 921. A movable plate 2 924 is provided above the movable plate 1 921. Two wedge plates 927 are provided between the movable plates 1 921 and 924. Electromagnet 2 928 is fixedly mounted on the opposite surfaces of the two wedge plates 927. Both electromagnets 928 are electrically connected to the temperature sensor 920. The sensing and driving assembly is configured to energize the ground of the wiring harness 10.

[0049] A connecting plate 20 is fixedly installed on the bottom surface of the socket 2 7, a fixed block 15 and a fixed block 2 16 are fixedly installed on one side surface of the detection frame 3, a spring piece 18 is installed between the fixed block 15 and the fixed block 2 16, a magnet block 17 is fixedly installed on one side surface of the detection frame 3, the magnet block 17 is located between the fixed block 15 and the fixed block 2 16, the magnet block 17 is electrically connected to the temperature sensor 920, a support column 19 is fixedly installed on one side surface of the connecting plate 20, one end of the support column 19 is in contact with one side surface of the spring piece 18.

[0050] During operation, when an abnormality occurs in the wiring harness 10 during the power-on detection process, that is, when an abnormality occurs after the wiring harness 10 is powered on, the temperature of the wiring harness 10 will continue to rise. When the temperature reaches the threshold of the temperature sensor 920, the magnet block 17 can be powered off. When the magnet block 17 is powered off, the spring 18 loses the adsorption of the magnet block 17 and can rebound toward the direction of the connecting plate 2 20, thereby driving the support column 19 and the connecting plate 2 20 to generate a force for movement, and then the socket 2 7 can be separated from the inside of the socket 1 4. That is, when an abnormality occurs during the power-on test, the wiring harness 10 can be automatically powered off, thereby ensuring the safety of the test.

[0051] A support 914 is fixedly installed on one side surface of the connecting plate 1 913, two limit pins 937 are fixedly installed inside the H-shaped frame 902, two clamping plates 915 are provided inside the H-shaped frame 902, and limit slots 936 are provided inside the two clamping plates 915. The clamping plates 915 are movably clamped to the inside of the H-shaped frame 902 through the limit slots 936, and an inclined plate 916 is movably connected between the clamping plates 915 and the support 914. The movable plate 1 921 is fixedly installed on the top surface of the clamping plate 915, and a mounting frame 922 is fixedly installed on the top surface of the movable plate 1 921. The interior of the mounting frame 922 is movably plugged with a plug-in frame 923. The movable plate 2 924 is fixedly installed on the top surface of the plug-in frame 923. The movable plate 2 924 is fixedly installed on the top surface of the plug-in frame 923. 24 and the opposite surface of the movable plate 1 921 are fixedly installed with mounting seats 925, and rollers 926 are installed inside the mounting seats 925. The wedge plate 927 is clamped between the two opposite mounting seats 925, and the outer surface of the roller 926 fits with the inclined surface of the wedge plate 927. An insulating plate 933 is fixedly installed on one end of the wedge plate 927, and a spring 934 is fixedly connected between one side surface of the insulating plate 933 and one side surface of the mounting frame 922. A conductive tube 929 is fixedly installed inside the movable plate 2 924, and a puncture needle 930 is fixedly installed on the top of the conductive tube 929. A conductive seat 931 is fixedly installed on the top surface of the movable plate 1 921, and a conductive wire 932 is connected between the conductive seat 931 and the conductive tube 929.

[0052] During operation, the movable plate 2 924 and the movable plate 1 921 can support the middle part of the wiring harness 10 during the placement of the wiring harness 10, so that the middle part of the wiring harness 10 can stay on the top of the movable plate 2 924 and will not fall down too much. Moreover, as the wiring harness 10 is gradually straightened by the moving block 905, it moves away from the top of the movable plate 2 924 and is located directly above the puncture needle 930. During the power-on test, the temperature sensor 920 senses the temperature of the wiring harness 10. When the temperature of the wiring harness 10 reaches the threshold set by the temperature sensor 920, the two electromagnets 2 928 can be controlled to be de-energized through the connecting plate 20. When the two electromagnets 2 928 are de-energized, the two wedge plates 927 can be re-energized by the spring 9 Under the action of 34, it moves rapidly toward the mounting bracket 922, thereby driving the movable plate 2 924 to move toward the direction of the wiring harness 10, that is, it moves upward rapidly, inserting the puncture needle 930 into the interior of the wiring harness 10, and making contact with the copper wire inside the wiring harness 10, so that the residual electricity inside the wiring harness 10 is transferred through the puncture needle 930 and the conductive wire 932 into the interior of the conductive seat 931, and finally discharged outward through the conductive seat 931, thereby ensuring that the residual electricity inside the wiring harness 10 can be released after the wiring harness 10 is powered off, avoiding the residual electricity inside the wiring harness 10 from causing secondary damage to the wiring harness 10 during the process of removing the wiring harness 10, affecting the accuracy of subsequent query problems, and also ensuring the safety of the operator.

[0054] During operation, when the first wire harness 10 is being tested, that is, after the C-shaped frame 917 moves downward, it can drive the movable plate 1 921 to move downward. After the two ends of the wire harness 10 are plugged into the inside of the socket 1 4, the bottom surface of the movable plate 1 921 contacts and presses the touch switch 935, which can control the start of the discharge motor 1202.

During the squeezing process, the gas inside the airbag 1406 can be transmitted to the inside of the air outlet pipe 1402, and finally transported into the inside of the air outlet frame 1401 through the air outlet pipe 1402, and finally sprayed toward the plug-in end of the wiring harness 10 through the air outlet frame 1401, blowing away the dust inside the plug-in end of the wiring harness 10, thereby achieving the purpose of automatically cleaning the plug-in end of the wiring harness 10, and can also automatically clean the outer surface of the wiring harness 10, thereby ensuring the accuracy of subsequent test data of the wiring harness 10, and can also ensure that the wiring harness 10 can be clearer during appearance inspection.

[0057] A method for detecting an automobile wiring harness comprises the following steps:

[0058] S1: First, place the wiring harness 10 inside the clamping groove 906 so that the plug-in ends of the wiring harness 10 are respectively located outside the two moving blocks 905. By controlling the detection motor 907 to start, the two moving blocks 905 are driven to move toward the socket 4 until the plug-in ends at both ends of the wiring harness 10 are plugged into the inside of the two sockets 4. Then, the wiring harness 10 can be powered on and tested by starting the power box 5.

[0059] S2: During the movement of the two moving blocks 905 toward the two sockets 4, the ductility of the wiring harness 10 can be tensile tested, and the strength of the plug ends at both ends of the wiring harness 10 can be tested simultaneously, thereby achieving the simultaneous tensile and plug end strength tests of the wiring harness 10 during the power-on test, and the test results can be displayed on the display 13;

[0060] S3: When an abnormality occurs in the wiring harness 10 during the power-on test, the temperature of the wiring harness 10 will continue to rise. When the temperature reaches the threshold of the temperature sensor 920, the power to the magnet block 17 is cut off, and the spring 18 loses the adsorption of the magnet block 17 and rebounds toward the connecting plate 20, driving the support column 19 and the connecting plate 2 to generate a force to move, separating the socket 2 7 from the interior of the socket 1 4, and automatically cutting off the power to the wiring harness 10, thereby ensuring the safety of the test;

[0061] S4: The temperature of the wiring harness 10 is sensed by the temperature sensor 920. When the temperature of the wiring harness 10 reaches the threshold set by the temperature sensor 920, the two electromagnets 2 928 are controlled to be powered off through the connecting plate 20. The two wedge plates 927 can quickly move toward the mounting bracket 922 under the action of the spring 934, driving the movable plate 2 924 to move toward the wiring harness 10, and inserting the puncture needle 930 into the interior of the wiring harness 10 to contact the conductive wire inside the wiring harness 10, so that the residual electricity inside the wiring harness 10 is transferred through the puncture needle 930 and the conductive wire 932 into the interior of the conductive seat 931, and finally discharged outward through the conductive seat 931, ensuring that the residual electricity inside the wiring harness 10 can be released after the wiring harness 10 is powered off.

[0062] Specifically, the working process or working principle of the detection device and detection method of the wiring harness 10 is as follows: when in use, during the process of starting the detection motor 907, it can drive the gear 1 908 to rotate, drive the threaded rods 911 at both ends of the connecting shaft 909 to rotate, and the threaded rods 911 at both ends of the gear 2 910 have opposite thread directions, so that the two moving blocks 905 move toward the direction of the socket 1 4 until the plug-in ends at both ends of the wiring harness 10 are plugged into the inside of the two sockets 1 4, and the wiring harness 10 is powered on by starting the power box 5. During the movement of the two moving blocks 905 toward the two sockets 1 4, the ductility of the wiring harness 10 can also be stretched and tested, and the strength of the plug-in ends at both ends of the wiring harness 10 can also be tested, thereby achieving the purpose of being able to perform tensile and plug-in end strength tests on the wiring harness 10 simultaneously during the power-on detection process, and the test results can be displayed on the display 13, replacing the existing single testing method, thereby greatly increasing the overall practicality of the device. When an abnormality occurs in the power-on detection process of the wiring harness 10, that is, when the wiring harness 1 0 After an abnormality occurs during power-on, the temperature of the wiring harness 10 will continue to rise. When the temperature reaches the threshold of the temperature sensor 920, the magnet block 17 can be powered off. When the magnet block 17 is powered off, the shrapnel 18 loses the adsorption of the magnet block 17 and can rebound toward the direction of the connecting plate 20, thereby driving the support column 19 and the connecting plate 20 to generate a force for movement, thereby being able to separate the socket 2 7 from the inside of the socket 1 4. That is, when an abnormality occurs during the power-on test, the wiring harness 10 can be automatically powered off, thereby To ensure the safety of the test, the bottom surface of the movable plate 921 contacts and presses the touch switch 935, which can control the start of the discharge motor 1202, driving the wire feed slot 1209 to rotate one circle inside the wire storage box 1201, and can transfer the wire harness 10 inside the placement slot 1205 to the inside of the wire bucket 1206, and the wire bucket 1206 transports it to the outer surface of the guide plate 1204, and slides to the C-type frame 917. The rotation of the discharge motor 1202 is controlled by the touch switch 935 to achieve the purpose of automatic unloading.

Its power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
