[0002] In the automotive manufacturing and repair field, the wiring harness of the automotive electrical box assembly is a key component of the electrical system, and its quality and safety are directly related to the performance and reliability of the entire vehicle. Once the insulation layer of the wiring harness is damaged, it is very easy to cause leakage. Therefore, it is essential to conduct comprehensive and accurate leakage detection on the wiring harness of the automotive electrical box assembly.

[0003] Existing testing devices are not suitable for flexibly and comprehensively detecting leakage current based on the actual length of the wiring harness when testing automotive electrical box assembly wiring harnesses. In actual testing, due to the varying lengths of the wiring harnesses, fixed testing devices cannot provide full coverage testing, resulting in some areas of the wiring harness not being effectively tested.

Beneficial effects

[0016] 1. This invention, by incorporating a proximity sensor and a metal plate, enables the control module B to reverse the drive motor when the auxiliary plate approaches the limit seat, causing the drive screw to move the drive seat in the opposite direction. Simultaneously, the double-ended screw C and the scale plate allow adjustment of the distance between the two sets of limit seats according to the specific length of the wire harness.

[0017] 2. This invention, by incorporating a magnetic ring and a Hall sensor, enables the magnetic field generated at the leakage location of the wire harness to influence the magnetic field of the magnetic ring when the magnetic ring moves to that location. The Hall sensor detects the change in the magnetic field of the magnetic ring, thereby enabling the detection of the leakage location of the wire harness. Simultaneously, the Hall sensor transmits the leakage signal to the control module B through the data acquisition module. The control module B then controls the drive motor to cut off the power and controls the laser marking head to accurately mark the leakage location.

[0018] 3. This invention, through the double-headed screw B and the adjusting seat, allows for convenient adjustment of the spacing and position of the clamping plates according to the thickness of the wire harness; at the same time, the anti-slip pad ensures that the wire harness is stably clamped without causing damage; this flexible clamping and adjustment method improves the adaptability of the device to different types of wire harnesses and makes operation more convenient.

[0019] 4. This invention, by providing a double-headed screw A and a movable frame, enables the clamping structure to drive the two ends of the wire harness to move in opposite directions, allowing the wire harness to unfold horizontally; simultaneously, when the clamping plate pulls the two ends of the wire harness through the anti-slip pad, the clamping plate can squeeze the pressure sensor through the rubber column; thus, it can conveniently control the pulling force on the two ends of the wire harness; ensuring that the pulling force is always within a suitable range, avoiding damage to the wire harness due to excessive pulling force or failure to fully unfold the wire harness due to insufficient pulling force.

[0045] Example 3: Please refer to Figures 6 to 8As shown: Based on Embodiments 1 and 2, the detection mechanism 5 includes: a detection frame 501, a control module B502, a data acquisition module 503, a timing module 504, a detection seat 505, a magnetic ring 506, and a Hall sensor 507; the detection frame 501 is fixedly mounted on the top of the drive seat 405; the control module B502 is fixedly mounted on the outside of the detection frame 501 and is electrically connected to the drive motor 403; the data acquisition module 503 is fixedly mounted on the outside of the detection frame 501 and is electrically connected to the proximity sensor 408, and is also electrically connected to the control module B502; the timing module 504 is fixedly mounted on the outside of the detection frame 501 and is electrically connected to the control module B502; the detection seat 505 is fixedly mounted on the top outside of the detection frame 501; the magnetic ring 506 is fixedly mounted on the detection seat 505.

[0046] The specific usage and function of this embodiment are as follows: In this invention, when in use, the two ends of the wire harness are placed between the two sets of clamping plates 302 respectively, and the wire harness is passed through the magnetic ring 506; then, the double-ended screw B203 is rotated by handwheel, and the double-ended screw B203 drives the adjusting seat 204 to slide within the adjusting frame 201. The adjusting seat 204 drives the clamping plate 302 to move through the adjusting frame 205, the fixing rod 206, and the sliding seat 301; so that the clamping plate 302 clamps and fixes the two ends of the wire harness through the anti-slip pad 303; the auxiliary motor 103 is started, and the auxiliary motor 103 drives the double-ended screw A102 to rotate. The double-ended screw A102 drives the clamping structure 3 to move horizontally through the two sets of moving frames 104, so that the wire harness is clamped and fixed. The two ends of the wire harness move in opposite directions, thus allowing the wire harness to unfold horizontally. During the unfolding process, the clamping plate 302 pulls the two ends of the wire harness through the anti-slip pad 303. The clamping plate 302 will squeeze the pressure sensor 208 through the rubber column 304. The pressure sensor 208 transmits the pressure signal to the control module A202 in real time. When the pressure value reaches the predetermined value, the control module A202 will control the auxiliary motor 103 to cut off the power, so that the moving frame 104 stops moving. This ensures that the pulling force is moderate, which can unfold the wire harness horizontally without damaging it. Then, the double-ended screw C406 is rotated by the handwheel. The double-ended screw C406 drives the two sets of limit seats 407 to move in opposite directions on the support platform 1. By observing the support... The scale plate 105 on the support platform 1 adjusts the two sets of limiting seats 407 to appropriate positions, so that the distance between the two sets of limiting seats 407 matches the length of the wiring harness; then, the power is connected to the wiring harness of the automotive electrical box assembly, putting it into a powered-on state; the drive motor 403 is started to drive the drive screw 402 to rotate, and the drive screw 402 drives the drive seat 405 to move horizontally through the guide rod 404, so that the detection frame 501 drives the magnetic ring 506 to move horizontally outside the wiring harness through the detection seat 505; when the magnetic ring 506 moves to the location of the wiring harness leakage, the change in current generated by the leakage will cause a change in the magnetic field at that location, and the Hall sensor 507 can sensitively detect the magnetic field around the magnetic ring 506. The system detects the leakage current and transmits the leakage signal to the data acquisition module 503. The data acquisition module 503 processes the received leakage signal and transmits it to the control module B502. Upon receiving the leakage signal, the control module B502 immediately de-energizes the drive motor 403, stopping the detection mechanism 5. Then, the control module B502 controls the laser marking head 602 to accurately mark the leakage location. The laser marking head 602 emits a laser beam, leaving a clear mark at the leakage location. Simultaneously, the control module B502 controls the timing module 504 to start timing. After the timing ends, the control module B502 restarts the drive motor 403, enabling the detection of the next leakage location.Simultaneously, the auxiliary plate 409 moves together with the drive base 405. When the metal plates 4010 on both sides of the auxiliary plate 409 approach the proximity sensor 408 at the top of the limit base 407, the proximity sensor 408 transmits a signal to the data acquisition module 503. The data acquisition module 503 then transmits the signal to the control module B502. The control module B502 controls the drive motor 403 to reverse, causing the drive base 405 to move in the opposite direction. This achieves the reciprocating movement of the detection mechanism 5 outside the wire harness, ensuring comprehensive inspection of the wire harness.
