[0033] When in use, firstly, the adjusting cylinder 23 is started by the control computer 2 so that the adjusting cylinder 23 is completely retracted, and then the movable plate 21 drives the movable block 20 to slide along the slide groove 5 through the adjusting plate 34, and then the automobile wiring harness is inserted into the power plug slot 19, and the adjusting cylinder 23 is started by the control computer 2 so that the adjusting cylinder 23 is extended, and the adjusting plate 34 is pushed to slide to both sides, and then the movable plate 21 is slid to both sides, so that the movable block 20 slides outward along the inner surface of the slide groove 5 until the automobile wiring harness is in a straight state, and then the adjusting cylinder 23 can be closed, and then the detection rotating block 18 is powered to the automobile wiring harness through the control computer 2, and the power supply current and power supply voltage are adjusted by the control computer 2 so that the power supply current and power supply voltage reach the maximum current and voltage of the automobile wiring harness, and the automobile wiring harness is operated for a period of time under the current and voltage to determine whether the automobile wiring harness meets the voltage level of the automobile using the automobile wiring harness, and at the same time, whether the automobile wiring harness exceeds the maximum temperature it can withstand under the current, and the data obtained by the detection is displayed by the control computer 2 to determine whether the automobile wiring harness meets the standard;

[0034] When the voltage level of the automobile wiring harness does not meet the regulations or the operating temperature of the automobile wiring harness exceeds the maximum temperature that the automobile wiring harness can withstand under the current, the automobile wiring harness is a defective product and needs to be repaired or destroyed and re-produced.

[0036] Reference Figure 1-Figure 7 , a detection semicircular ring 9 is arranged on the top of the detection platform 1, and a leakage detection column 10 is installed inside the detection semicircular ring 9. The leakage detection column 10 is arranged in a ring array along the central axis of the hollow cylinder composed of two detection semicircular rings 9, and the number of the leakage detection columns 10 is twelve. The leakage detection column 10 is electrically connected to the control computer 2, and the leakage detection column 10 is controlled by the control computer 2. The leakage detection column 10 is in contact with the outer surface of the automobile wiring harness to detect whether the automobile wiring harness has leakage. It also includes a servo motor 3 arranged at the end of the detection platform 1, and the servo motor 3 is connected to the control computer 2. Computer 2 is electrically connected, and the servo motor 3 is controlled by the control computer 2. The output end of the servo motor 3 is fixedly connected with a threaded rotating rod 4, and the threaded rotating rod 4 passes through the movable block 20. The threaded rotating rod 4 is connected with a slider 6 through a thread. The slider 6 is slidably connected to the inside of the slide groove 5. The top of the slider 6 is fixedly connected with a fixed slide 7, and a clamping cylinder 8 is installed on the fixed slide 7. The clamping cylinder 8 is electrically connected to the control computer 2 and is controlled by the control computer 2. The fixed slide 7 is slidably connected to the top of the detection table 1, and the detection semicircular ring 9 is installed at the output end of the clamping cylinder 8.

[0037] After the automobile wiring harness is plugged into the powered plug slot 19, the automobile wiring harness can be placed between the detection semicircular rings 9, and then the clamping cylinder 8 is started by the control computer 2 to make the clamping cylinder 8 fully extended, so that the detection semicircular ring 9 wraps the automobile wiring harness. At this time, the leakage detection column 10 is in contact with the automobile wiring harness. When detecting whether the automobile wiring harness has leakage, the servo motor 3 is started by the control computer 2 so that the servo motor 3 drives the threaded rotating rod 4 to rotate, thereby making the slider 6 slide along the inner surface of the slide groove 5. The sliding of the slider 6 will drive the fixed slide 7 to slide, and then drive the detection semicircular ring 9 to slide through the clamping cylinder 8. , so that the leakage detection column 10 slides along the outer surface of the automobile wiring harness. When the detection semicircular ring 9 slides to contact the detection rotating block 18 on one side, the control computer 2 will automatically switch the rotation direction of the servo motor 3, so that the detection semicircular ring 9 contacts the detection rotating block 18 on the other side, until the leakage detection column 10 performs a full range of detection on the automobile wiring harness in the horizontal direction, and performs a horizontal leakage detection on the outer surface of the automobile wiring harness. When the leakage detection column 10 detects that the automobile wiring harness has leakage, the leakage detection column 10 sends the detected data to the control computer 2, and the control computer 2 records the leakage position;

[0038] The back and forth sliding of the leakage detection column 10 can perform horizontal all-round detection on whether the automobile wiring harness has leakage, thereby ensuring that the automobile wiring harness meets the production requirements and ensuring the safety of the electrical system of the automobile using the automobile wiring harness.

[0039] Reference Figure 2 , Figure 4 , Figure 8 , also includes a transmission shaft 15 rotatably connected to the movable plate 21, the top of the transmission shaft 15 is fixedly connected to the third bevel gear 16, and the bottom of the transmission shaft 15 is fixedly connected to the second bevel gear 14, wherein a fourth bevel gear 17 is fixedly connected to the detection rotating block 18, and the fourth bevel gear 17 is meshed with the third bevel gear 16, a movable groove 11 is provided on the threaded rotating rod 4, and a groove is provided in the movable block 20, and the first bevel gear 13 is rotatably connected in the groove, and a limiting slide 12 is fixedly connected in the first bevel gear 13, the movable groove 11 and the limiting slide 12 are both set to a cross shape, and the two are adapted to each other, the limiting slide 12 is slidably connected to the movable groove 11, and the second bevel gear 14 is meshed with the first bevel gear 13.

[0040] When the movable plate 21 is adjusting its position, the movable plate 21 will drive the first bevel gear 13 to move, so that the limiting slide 12 slides along the movable groove 11 until the movable plate 21 is adjusted to a suitable position. In the process of performing leakage detection on the automobile wiring harness, the rotation of the threaded rotating rod 4 will drive the first bevel gear 13 to rotate through the movable groove 11 and the limiting slide 12, thereby causing the second bevel gear 14 to rotate. The rotation of the second bevel gear 14 will drive the third bevel gear 16 to rotate through the transmission shaft 15, and the rotation of the third bevel gear 16 will drive the detection through the fourth bevel gear 17. The rotating block 18 rotates, and the detection rotating blocks 18 on both sides rotate synchronously at the same speed (the synchronous and same-speed rotation of the detection rotating block 18 prevents the automobile wiring harness from having torque, which causes the outer surface of the automobile wiring harness to be uneven, and causes the leakage detection column 10 to be unable to contact the leakage part of the outer surface of the automobile wiring harness. The synchronous and same-speed rotation can eliminate this hidden danger, so that the leakage detection column 10 can contact the leakage part of the automobile wiring harness, thereby ensuring the accuracy of leakage detection), thereby driving the automobile wiring harness to rotate. During the rotation of the automobile wiring harness, the leakage detection column 10 is in a horizontal movement state;

[0041] Thereby, the leakage detection column 10 can perform leakage detection on the entire circular surface and horizontal direction of the automobile wiring harness, realize all-round leakage detection of the automobile wiring harness, expand the detection range, and ensure the accuracy of detection. Through leakage detection, possible defects or damages in the automobile wiring harness can be discovered and repaired in time, thereby ensuring the normal operation and service life of the automobile using the automobile wiring harness, and at the same time helping to prevent potential safety risks in advance, and can detect whether the insulation layer of the automobile wiring harness is aging, thereby ensuring the safety and reliability of the automobile wiring harness.

[0042] Reference Figure 1-Figure 7, also includes a piston cylinder 24 fixedly connected to both ends of the detection platform 1, a piston plate 26 is slidably connected inside the piston cylinder 24, an air inlet hole 25 is provided at the bottom of the piston cylinder 24, a one-way valve is provided in the air inlet hole 25, so that the piston cylinder 24 can only draw outside air into the piston cylinder 24 through the air inlet hole 25, an exhaust hose 27 is fixedly connected to the top of the piston cylinder 24, a one-way valve is provided in the exhaust hose 27, so that the air in the piston cylinder 24 can only be discharged through the exhaust hose 27, and an injection hose 29 is fixedly connected to the end of the exhaust hose 27 away from the piston cylinder 24, wherein an air injection chamber 30 is provided inside the side wall of the detection semicircular ring 9, a cleaning brush 31 is fixedly connected to the inner surface of the detection semicircular ring 9, and the cleaning brush 31 is arranged at both ends of the inner surface of the detection semicircular ring 9, and the leakage detection column 10 is provided Between the cleaning bristles 31, the jet hole 32 is arranged at the position where the cleaning bristles 31 are fixedly connected to the detection semicircular ring 9, and the jet hole 32 is arranged between adjacent cleaning bristles 31.

The top of the movable plate 21 is fixedly connected with a guide ring 28, the exhaust hose 27 passes through the guide ring 28 and is slidably connected to the guide ring 28. Through the setting of the guide ring 28, the exhaust hose 27 is prevented from being entangled when the detection semicircular ring 9 moves back and forth, which affects the efficiency of the leakage detection of the automobile wiring harness.

[0043] When the detection semicircular ring 9 is in the process of horizontal movement, the cleaning bristles 31 will clean the outer surface of the automobile wiring harness. At the same time, since the automobile wiring harness is in a rotating state when the detection semicircular ring 9 is in the horizontal movement state, the cleaning bristles 31 can clean the outer surface of the automobile wiring harness in an all-round manner;

[0044] Therefore, the leakage detection column 10 can detect the entire circular surface of the automobile wiring harness, realize all-round leakage detection of the automobile wiring harness, expand the detection range, and ensure the detection accuracy;

[0045] During the rotation of the threaded rotating rod 4, the piston plate 26 will slide back and forth along the inner surface of the piston cylinder 24 under the action of the reciprocating thread wire 33, so that the piston cylinder 24 at one end draws external air into the piston cylinder 24 through the air inlet hole 25, and the piston cylinder 24 at the other end will squeeze the air inside into the exhaust hose 27 under the action of the piston plate 26, and then enter the jet air chamber 30 through the air injection hose 29, and act on the outer surface of the automobile wiring harness through the jet hole 32, and cooperate with the cleaning bristles 31 to clean the dust and other impurities in the worn parts of the automobile wiring harness to prevent dust and other impurities from adhering to the worn parts of the automobile wiring harness, resulting in the leakage current cannot be detected by the leakage detection column 10 and affecting the detection accuracy. At the same time, the automobile wiring harness can be cooled to prevent leakage in the leakage part of the automobile wiring harness, which will cause the automobile wiring harness to heat up and locally burn due to hot melting, resulting in the worn automobile wiring harness being unable to be repaired, increasing the production burden and affecting the safety of automobile wiring harness detection.

[0046] The working principle of the automotive wiring harness detection device after the detection is completed is as follows:

[0047] By controlling the computer 2 to turn off the servo motor 3, and then starting the clamping cylinder 8 to make the clamping cylinder 8 fully retracted, so that the detection semicircular ring 9 cannot wrap the automobile wiring harness, and then starting the adjusting cylinder 23 to make the adjusting cylinder 23 fully retracted, and then driving the movable plate 21 to slide in the adjacent direction through the adjusting plate 34, the automobile wiring harness can be removed from the powered plug slot 19, and the detection of the automobile wiring harness is completed. When detecting the next automobile wiring harness, repeat the above operation.
