[0014] An automobile wire harness detection method includes the following steps: S1: First, place the wire harness inside the clamping groove so that the plug-in ends of the wire harness are respectively located outside the two moving blocks. By controlling the detection motor to start, drive the two moving blocks to move towards the direction of the first socket until the plug-in ends at both ends of the wire harness are inserted into the two first sockets. Then, the wire harness can be powered on and tested by starting the power supply box. S2: During the process of the two moving blocks moving towards the two sockets 1, it is also possible to conduct a tensile test on the ductility of the wire harness, and at the same time, it is also possible to conduct a strength test on the plug-in ends at both ends of the wire harness, thereby achieving the purpose of being able to conduct tensile and plug-in end strength tests on the wire harness synchronously during the power-on detection process, and the test results can be displayed through a display; S3: When an abnormality occurs during the power-on detection of the wire harness, the temperature of the wire harness will continue to rise. When the temperature reaches the threshold of the temperature sensor, the magnet block 1 is powered off, the elastic piece loses the adsorption of the magnet block 1, rebounds towards the direction of the connecting plate 2, drives the force generated by the contact post and the connecting plate 2 to move, separates the socket 2 from the inside of the socket 1, and achieves the purpose of automatically powering off the wire harness, thereby ensuring the safety of the test; S4: The temperature sensor senses the temperature of the wire harness. When the temperature of the wire harness reaches the threshold set by the temperature sensor, the two electromagnets 2 are controlled to be powered off through the connecting plate 2. The two wedge plates can move rapidly towards the direction of the mounting bracket under the action of the spring, drive the movable plate 2 to move towards the wire harness, insert the puncture needle into the inside of the wire harness, and make contact with the conductive wire inside the wire harness, so that the residual power inside the wire harness is transmitted through the puncture needle and the conductive wire into the inside of the conductive seat, and finally discharged outward through the conductive seat, achieving the purpose of being able to release the residual power inside the wire harness after the wire harness is powered off.

[0015] The beneficial effects of an automotive wire harness detection device provided by the present invention include: 1. By setting up a test component, during the process of starting the detection motor, it can drive the gear 1 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 the gear 2 are opposite, so that the two moving blocks move towards the socket 1 until the plug-in ends at both ends of the wire harness are inserted into the two sockets 1. The wire harness is powered on and tested by starting the power supply box. During the process of the two moving blocks moving towards the two sockets 1, it is also possible to conduct a tensile test on the ductility of the wire harness, and at the same time, it is also possible to conduct a strength test on the plug-in ends at both ends of the wire harness, thereby achieving the purpose of being able to conduct tensile and plug-in end strength tests on the wire harness synchronously during the power-on detection process, and the test results can be displayed through a display, replacing the existing single test method, thereby greatly increasing the overall practicality of the device.

[0016] 2. By setting up a sensing drive component, when an abnormality occurs during the power-on detection of the wire harness, that is, after an abnormality occurs when the wire harness is powered on, the temperature of the wire harness will continuously rise. When the temperature reaches the threshold of the temperature sensor, the power supply to the first magnet block can be cut off. After the first magnet block is powered off, the elastic piece loses the adsorption of the first magnet block and can rebound towards the direction of the second connecting plate, thereby driving the abutting column to generate a force for moving the second connecting plate, and further being able to separate the second socket from the inside of the first socket. That is, when an abnormality occurs during the power-on test, the wire harness can be automatically powered off, thereby ensuring the safety of the test.

[0017] 3. By setting up a cleaning component, when the bottom surface of the first movable plate touches and presses the touch switch, the feeding motor can be controlled to start, driving the wire inlet groove to rotate one circle inside the wire storage box, so that the wire harness in the placement groove can be transported into the inside of the wire guide hopper, and then enter the outer surface of the guide plate through the transportation of the wire guide hopper and slide to the C-shaped frame. By controlling the rotation of the feeding motor through the touch switch, the purpose of automatic feeding can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0021] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figures 1 - 11, the present invention provides a technical solution: an automotive wire harness detection device, including a main chassis 1, a top plate 2 is fixedly installed on the top surface of the main chassis 1, both ends of the top surface of the top plate 2 are fixedly installed with detection frames 3, a socket one 4 is fixedly installed inside the detection frame 3, a power supply box 5 is arranged on one side of each detection frame 3, a connecting wire 6 is fixedly connected to one side of the power supply box 5, a socket two 7 is fixedly installed at one end of the connecting wire 6, and the socket two 7 is inserted inside the socket one 4. A detection table 8 is fixedly installed between the two sockets one 4, a detection mechanism 9 is arranged inside the detection table 8, a wire harness 10 is placed inside the detection mechanism 9, a feeding component 12 is arranged on the top surface of the main chassis 1, and a display 13 is arranged on one side of the feeding component 12; When testing the wire harness 10, only the wire harness 10 to be detected needs to be uniformly placed inside the feeding component 12, and then the feeding component 12 can discharge the wire harness 10 for visual detection. And the wire harness 10 is cleaned by the cleaning component 14 to prevent residual dust on the plug joints of the wire harness 10 from affecting the subsequent test. During the test process, multiple tests such as power-on test and tensile test can be carried out on the wire harness 10, and the test results and test data are displayed in real time through the display 13, so as to realize the test operation of the wire harness 10.

[0023] The detection mechanism 9 includes a test component and a sensing drive component. The test component includes a through groove 901, an H-shaped frame 902 is fixedly installed inside the through groove 901, sliding groove frames 903 are fixedly installed at both ends of the H-shaped frame 902, T-shaped frames 904 are movably clamped inside the sliding groove frames 903, moving blocks 905 are fixedly installed at the tops of the T-shaped frames 904, and the test component is arranged for testing the wire harness 10; A detection motor 907 is fixedly installed inside the main chassis 1, a gear one 908 is fixedly installed at the output end of the detection motor 907, a connecting plate one 913 is fixedly installed on the bottom surface of the T-shaped frame 904, a socket frame 912 is fixedly installed on the bottom surface of the connecting plate one 913, threaded rods 911 are threadedly sleeved inside the socket frames 912, a connecting shaft 909 is fixedly connected between the two threaded rods 911, a gear two 910 is fixedly installed on the outer surface of the connecting shaft 909, the gear two 910 meshes with the gear one 908, a clamping groove 906 is opened on the top surface of the sliding groove frame 903, and both ends of the wire harness 10 are respectively clamped inside the two clamping grooves 906. A C-shaped frame 917 is fixedly installed on one side surface of the movable plate one 921, a cross plate 918 is fixedly installed at one end of the C-shaped frame 917, a temperature sensor 920 is fixedly installed on the top surface of the cross plate 918, and anti-disengagement plates 919 are fixedly installed at both ends of the cross plate 918.

[0024] During operation, in the process of testing the wire harness 10, first place the wire harness 10 inside the clamping groove 906 so that the plug ends of the wire harness 10 are respectively located outside the two moving blocks 905. Then, start the detection motor 907 by control. During the startup process of the detection motor 907, it can drive the first gear 908 to rotate. During the rotation of the first gear 908, it can drive the connecting shaft 909 to rotate under the action of the second gear 910, thereby driving the threaded rods 911 at both ends of the connecting shaft 909 to rotate. Moreover, the threaded directions of the threaded rods 911 at both ends of the second gear 910 are opposite. Therefore, when the detection motor 907 rotates, it can drive the two socket frames 912 to move in opposite directions under the action of the threads, thereby driving the two moving blocks 905 to move towards the first socket 4 until the plug ends at both ends of the wire harness 10 are inserted into the two first sockets 4. Then, the wire harness 10 can be powered on and tested by starting the power supply box 5. And, during the movement of the two moving blocks 905 towards the two first sockets 4, the extensibility of the wire harness 10 can also be subjected to a tensile test, and at the same time, the strength of the plug ends at both ends of the wire harness 10 can also be tested. Thus, it realizes that during the power-on detection of the wire harness 10, the tensile test and the plug end strength test can be carried out synchronously, and the test results can be displayed through the display 13, replacing the existing single test method, thereby greatly increasing the overall practicality of the device.

[0025] Moreover, during the test, that is, when the two moving blocks 905 move towards both ends, the test data is the data after the wire harness 10 is stretched, that is, after the wire harness 10 is stretched and then powered on for testing, which can better simulate the harsh environment during the actual use of the wire harness 10, improve the test intensity of the wire harness 10, that is, contribute to the improvement of the quality of the wire harness 10 in the quality room after the test, thereby improving the safety of the wire harness 10 after it is put into use.

[0026] The above test process is a sampling test, that is, multiple representative wire harnesses 10 are selected for testing, and the tested wire harnesses 10 are numbered separately to represent a batch of wire harnesses 10.

[0027] Through the provided C-shaped frame 917, during the process of the two connecting plates 913 moving in opposite directions, the movable plate 921 and the movable plate 924 can be driven to move downward under the action of the inclined plate 916, thereby driving the C-shaped frame 917 mounted on one side surface of the movable plate 921 to move downward synchronously. Furthermore, the anti-disengagement plates 919 at both ends of the C-shaped frame 917 are driven to move downward, enabling the anti-disengagement plates 919 to be clamped into the interior of the clamping groove 906 to limit the wire harness 10, thus ensuring the stability during subsequent stretching and power-on testing processes, and preventing the wire harness 10 from disengaging from the interior of the clamping groove 906 during the testing process. Moreover, during the downward movement of the C-shaped frame 917, the temperature sensor 920 can also be driven to move downward synchronously. After the insertion end of the wire harness 10 is inserted into the interior of the socket 4, the sensing end of the temperature sensor 920 is in contact with the outer surface of the wire harness 10, enabling real-time monitoring of the temperature during the power-on testing of the wire harness 10 to ensure the safety of the wire harness 10 during the power-on testing, and the monitored real-time temperature will be displayed on the display 13.

[0028] The sensing and driving assembly includes a temperature sensor 920 and a movable plate 921. Above the movable plate 921, there is a movable plate 924. Between the movable plate 921 and the movable plate 924, there are two wedge plates 927. On the opposite surfaces of the two wedge plates 927, electromagnets 928 are fixedly installed. Both electromagnets 928 are electrically connected to the temperature sensor 920. The setting of the sensing and driving assembly is used for grounding and powering on the wire harness 10. On the bottom surface of the socket 7, a connecting plate 20 is fixedly installed. On one side surface of the detection frame 3, a fixing block 15 and a fixing block 16 are fixedly installed. A spring piece 18 is installed between the fixing block 15 and the fixing block 16. On one side surface of the detection frame 3, a magnet block 17 is fixedly installed. The magnet block 17 is located between the fixing block 15 and the fixing block 16, and the magnet block 17 is electrically connected to the temperature sensor 920. On one side surface of the connecting plate 20, a resisting post 19 is fixedly installed. One end of the resisting post 19 is in contact with one side surface of the spring piece 18.

[0029] During operation, when an abnormality occurs during the power-on detection of the wire harness 10, that is, after an abnormality occurs during the power-on of the wire harness 10, the temperature of the wire harness 10 will continuously rise. When the temperature reaches the threshold of the temperature sensor 920, the magnet block 17 can be powered off. After the magnet block 17 is powered off, the spring piece 18 loses the adsorption of the magnet block 17 and can rebound towards the direction of the connecting plate 20, thereby driving the resisting post 19 and the connecting plate 20 to generate a force for movement, and further enabling the socket 7 to be disengaged from the interior of the socket 4. That is, when an abnormality occurs during the power-on test, the wire harness 10 can be automatically powered off, thus ensuring the safety of the test.

[0030] On one side surface of the first connecting plate 913, supports 914 are fixedly installed. Inside the H-shaped frame 902, two limit pins 937 are fixedly installed. Inside the H-shaped frame 902, there are two clamping plates 915. Inside both of the two clamping plates 915, limit grooves 936 are formed. The clamping plates 915 are movably clamped inside the H-shaped frame 902 through the limit grooves 936. An inclined plate 916 is movably connected between the clamping plate 915 and the support 914. The first movable plate 921 is fixedly installed on the top surface of the clamping plate 915. An installation frame 922 is fixedly installed on the top surface of the first movable plate 921. An insertion frame 923 is movably inserted inside the installation frame 922. The second movable plate 924 is fixedly installed on the top surface of the insertion frame 923. Installation seats 925 are fixedly installed on the opposite surfaces of the second movable plate 924 and the first movable plate 921. Rollers 926 are installed inside the installation seats 925. A wedge plate 927 is clamped between the two opposite installation seats 925, and the outer surface of the roller 926 is in contact with the inclined surface of the wedge plate 927. Insulating plates 933 are fixedly installed at one end of the wedge plate 927. A spring 934 is fixedly connected between the side surface of the insulating plate 933 and the side surface of the installation frame 922. A conductive cylinder 929 is fixedly installed inside the second movable plate 924. A puncture needle 930 is fixedly installed at the top end of the conductive cylinder 929. A conductive seat 931 is fixedly installed on the top surface of the first movable plate 921. A conductive wire 932 is connected between the conductive seat 931 and the conductive cylinder 929.

[0031] During operation, through the arranged movable plate II 924 and movable plate I 921, the middle part of the wire harness 10 can be supported during the placement process of the wire harness 10, so that the middle part of the wire harness 10 can stay on the top of the movable plate II 924 and will not drop too much downward. Moreover, after the wire harness 10 is gradually straightened driven by the moving block 905, it moves away from the top of the movable plate II 924 and is located directly above the puncture needle 930. During the power-on test process, the temperature sensor 920 senses the temperature of the wire harness 10. When the temperature of the wire harness 10 reaches the threshold value set by the temperature sensor 920, the two electromagnets II 928 can be controlled to power off through the connecting plate II 20. When the two electromagnets II 928 are powered off, the two wedge plates 927 can quickly move towards the mounting frame 922 under the action of the spring 934, thereby driving the movable plate II 924 to move towards the wire harness 10, that is, quickly move upward, insert the puncture needle 930 into the interior of the wire harness 10, and make contact with the copper wire inside the wire harness 10, so that the residual electricity inside the wire harness 10 is transmitted through the puncture needle 930 and the conducting wire 932 into the interior of the conducting seat 931, and finally discharged outward through the conducting seat 931, thus ensuring the purpose of releasing the residual electricity inside the wire harness 10 after the wire harness 10 is powered off, avoiding secondary damage to the wire harness 10 caused by the residual electricity inside the wire harness 10 during the process of taking out the wire harness 10, affecting the accuracy of subsequent problem query, and also ensuring the safety of the operator.

A plurality of cameras 22 are fixedly installed on the bottom surface of the external connection plate 21.

[0033] During operation, when the first wire harness 10 is being detected, that is, after the C-shaped frame 917 moves downward, it can drive the first movable plate 921 to move downward. After both ends of the wire harness 10 are inserted into the first socket 4, the bottom surface of the first movable plate 921 contacts and presses the touch switch 935, which can control the feeding motor 1202 to start. During the startup process of the feeding motor 1202, it can drive the rotating shaft 1207 to rotate, thereby driving the wire inlet groove 1209 to rotate one circle inside the wire storage box 1201 until the touch switch 935 is touched again. When the roller 1208 rotates one circle, it can transfer the wire harness 10 in the placement groove 1205 into the wire guide hopper 1206, and through the conveyance of the wire guide hopper 1206, it enters the outer surface of the guide plate 1204 and slides to the C-shaped frame 917. Since during the test of the previous wire harness 10, it can cause the C-shaped frame 917 to move downward, thereby driving the external connection plate 21 to move downward, enabling the camera 22 on the bottom surface of the external connection plate 21 to closely photograph the outer surface of the wire harness 10, thus realizing the detection of the appearance of the wire harness 10, and the detection result can be transmitted to the display 13 for display. Moreover, by controlling the rotation of the feeding motor 1202 through the touch switch 935, the purpose of automatic feeding can also be achieved, avoiding the problem of multiple wire harnesses 10 to be tested being stacked together and getting disordered.

[0034] A cleaning component 14 is arranged inside the main chassis 1. The cleaning component 14 includes a box body 1404. An airbag 1406 is installed inside the box body 1404. A clamping groove 1405 is formed on the top surface of the box body 1404. A push plate 1407 is movably clamped inside the box body 1404. The push plate 1407 is located on one side of the airbag 1406. A connecting column 1408 is fixedly installed on the top surface of the push plate 1407. The connecting column 1408 is movably clamped inside the clamping groove 1405.

Air outlet frames 1401 are fixedly installed at both ends of the top surface of the detection table 8. The air outlet frames 1401 are located on one side of the guide plate 1204. An air outlet pipe 1402 is fixedly connected to one side surface of the air outlet frame 1401.

A one-way valve 1410 is fixedly installed on the outer surface of the gas inlet pipe 1409.

[0035] During operation, when the two socket frames 912 move in opposite directions, they can synchronously drive the connection column 1408 and the push plate 1407 to move, thereby squeezing the airbag 1406. During the squeezing process, the gas inside the airbag 1406 can be transmitted into the inside of the air outlet pipe 1402, and finally enter the inside of the air outlet frame 1401 through the transportation of the air outlet pipe 1402. Finally, it is sprayed out from the air outlet frame 1401 towards the insertion end of the wire harness 10, blowing away the dust inside the insertion end of the wire harness 10, thus achieving the purpose of automatically cleaning the insertion end of the wire harness 10, and it can also automatically clean the outer surface of the wire harness 10, thereby ensuring the accuracy of the subsequent test data of the wire harness 10, and it can also ensure that the wire harness 10 is clearer during the appearance inspection.

[0036] An automobile wire harness detection method includes the following steps: S1: First, place the wire harness 10 inside the clamping groove 906, so that the insertion ends of the wire harness 10 are respectively located outside the two moving blocks 905. By controlling the detection motor 907 to start, drive the two moving blocks 905 to move towards the direction of the socket one 4 until the insertion ends at both ends of the wire harness 10 are inserted into the two sockets one 4. Then, the wire harness 10 can be powered on and tested by starting the power supply box 5. S2: During the process of the two moving blocks 905 moving towards the two sockets one 4, the extensibility of the wire harness 10 can also be stretched and tested, and at the same time, the strength of the insertion ends at both ends of the wire harness 10 can also be tested. Thus, during the power-on detection of the wire harness 10, the stretching and the strength of the insertion ends can be synchronously tested, and the test results can be displayed on the display 13. S3: When an abnormality occurs during the power-on detection of the wire harness 10, the temperature of the wire harness 10 will continuously rise. When the temperature reaches the threshold of the temperature sensor 920, the magnet block one 17 is powered off, and the elastic piece 18 loses the adsorption of the magnet block one 17 and rebounds towards the direction of the connecting plate two 20, driving the force generated by the contact post 19 and the connecting plate two 20 to move, disengaging the socket two 7 from the inside of the socket one 4, achieving the purpose of automatically powering off the wire harness 10, thereby ensuring the safety of the test. S4: The temperature of the wire harness 10 is sensed by the temperature sensor 920. When the temperature of the wire harness 10 reaches the threshold set by the temperature sensor 920, the two electromagnets two 928 are controlled to cut off the power through the connecting plate two 20. The two wedge plates 927 can quickly move towards the mounting bracket 922 under the action of the spring 934, driving the movable plate two 924 to move towards the wire harness 10, inserting the puncture needle 930 into the interior of the wire harness 10, making contact with the conductive wire inside the wire harness 10, so that the residual power inside the wire harness 10 is transmitted 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 the purpose of releasing the residual power inside the wire harness 10 after the wire harness 10 is powered off.

[0037] Specifically, the working process or working principle of the wire harness 10 detection device and detection method is as follows: When in use, during the startup process of the detection motor 907, it can drive the gear one 908 to rotate, driving the threaded rods 911 at both ends of the connecting shaft 909 to rotate. Moreover, the threaded directions of the threaded rods 911 at both ends of the gear two 910 are opposite, causing the two moving blocks 905 to move towards the socket one 4 until the plug-in ends at both ends of the wire harness 10 are inserted into the two sockets one 4. The wire harness 10 is powered on and tested by starting the power supply box 5. During the movement of the two moving blocks 905 towards the two sockets one 4, the extensibility of the wire harness 10 can also be subjected to a tensile test, and at the same time, the strength of the plug-in ends at both ends of the wire harness 10 can be tested. Thus, the purpose of being able to synchronously perform tensile and plug-in end strength tests on the wire harness 10 during the power-on detection process is achieved, and the test results can be displayed through the display 13, replacing the existing single test means, thereby greatly increasing the overall practicality of the device. When an abnormality occurs during the power-on detection of the wire harness 10, that is, when an abnormality occurs after the wire harness 10 is powered on, the temperature of the wire harness 10 will continuously rise. After the temperature reaches the threshold of the temperature sensor 920, the electromagnet block one 17 can be powered off. After the electromagnet block one 17 is powered off, the elastic piece 18 loses the adsorption of the electromagnet block one 17 and can rebound towards the connecting plate two 20, thereby driving the contact post 19 to generate a force for movement with the connecting plate two 20, and further being able to disconnect the socket two 7 from the interior of the socket one 4. That is, when an abnormality occurs during the power-on test, the purpose of automatically powering off the wire harness 10 can be achieved, thereby ensuring the safety of the test. When the bottom surface of the movable plate one 921 touches and presses the touch switch 935, it can control the feeding motor 1202 to start, driving the wire inlet groove 1209 to rotate one circle inside the wire storage box 1201, being able to transmit the wire harness 10 inside the placement groove 1205 into the interior of the wire guide hopper 1206, and being conveyed by the wire guide hopper 1206 to the outer surface of the guide plate 1204 and sliding to the C-shaped frame 917. Controlling the rotation of the feeding motor 1202 through the touch switch 935 can achieve the purpose of automatic feeding.

[0038] It should be noted that the air outlet pipe 1402 is a device or equipment existing in the prior art, or a device or equipment that can be realized by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they will not be elaborated in detail.
