[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example: Figures 1-3 As shown, the present invention provides a technical solution for a new energy vehicle wiring harness insulation performance testing device with a feeding function. The testing device includes a mounting frame 1, on which a feeding plate 2, a testing platform 3, and a testing instrument 4 are mounted. The feeding plate 2 is equipped with a control panel 5, a conveying component 6, a vision detector 11, and a first module slide rail 7. A first slider 8 is slidably mounted on the first module slide rail 7. A second module slide rail 9 is mounted on the first slider 8. A second slider 10 is mounted on the second module slide rail 9. A rotating cylinder 12 is mounted on the second slider 10. Several support rods 13 are mounted on the rotating cylinder 12. Telescopic cylinders 14 are mounted at the ends of the support rods 13. Mechanical claws 15 are mounted at the lower ends of the telescopic cylinders 14. A testing insertion hole 16 is provided on the testing platform 3.

[0035] The control panel 5 is electrically connected to the vision detector 11, the conveyor 6, the first module slide rail 7, the second module slide rail 9, the rotary cylinder 12, the telescopic cylinder 14, and the mechanical gripper 15. The control panel 5 is responsible for coordinating the entire inspection process.

[0036] When the inspection begins, the control panel 5 controls the conveyor 6 to transport the wire harness to be inspected. When the wire harness passes the vision detector 11, the vision detector 11 detects the position of the interface terminal and transmits the position information back to the control panel 5. Based on the feedback information, the control panel 5 controls the first slider 8 to slide along the first module slide rail 7 and the second slider 10 to slide along the second module slide rail 9. The rotating cylinder 12 drives the support rod 13 to rotate, so that the mechanical claw 15 is suspended above the interface terminal. Then, the telescopic cylinder 14 is controlled to extend, driving the mechanical claw 15 to approach and grab the interface terminal. Subsequently, the interface terminal is inserted into the detection socket 16, and the inspection instrument 4 is started to perform the inspection.

[0037] Vehicle wiring harnesses typically consist of multiple interface terminals. The visual detector 11 and the mechanical gripper 15 work together to ensure the accurate connection and detection of these terminals, enabling automatic and accurate feeding, improving detection efficiency and ensuring detection accuracy.

[0038] The testing platform 3 has a discharge port 17.

[0039] After the test is completed, the tester 4 records the test data, and the control panel 5 controls the mechanical claw 15 to pull the wire harness out of the test position and discharge the tested wire harness from the discharge port 17. This facilitates material unloading and improves the automation level of the test device. Wire harness testing often uses high-voltage current. Improving the automation level can avoid injury to the testing personnel, improve testing efficiency, and reduce the risk factor of testing.

[0040] A cleaning component 18 and a drain component 19 are provided at the test socket 16. The cleaning component 18 cleans the test connection before each test, and the drain component 19 removes the dust accumulated in the cleaning component 18.

[0041] like Figures 3-4 and Figures 6-8 As shown, the cleaning assembly 18 includes a mounting slot 1801, a first micro motor 1802, a drive gear 1803, a driven gear ring 1804, an air duct slot 1805, an air inlet pipe 1806, a jet nozzle 1807, a mounting base 1808, a detection socket 1809, an air ring 1810, an air delivery pipe 1811, and an air pump 1812;

[0042] The testing platform 3 has a mounting slot 1801, in which a first micro motor 1802, a drive gear 1803, and a driven gear ring 1804 are installed. The output shaft of the first micro motor 1802 is connected to the drive gear 1803, and the drive gear 1803 meshes with the driven gear ring 1804. The driven gear ring 1804 is coaxial with the testing socket 16. The testing platform 3 has an air pipe slot 1805, in which an air inlet pipe 1806 is installed inside the driven gear ring 1804. An air nozzle 1807 is installed on the side of the air inlet pipe 1806 away from the driven gear ring 1804, which is placed in the air pipe groove 1805. A mounting base 1808 is installed at the lower end of the detection socket 16. A detection socket 1809 is installed on the mounting base 1808. An air ring 1810 is rotatably installed in the mounting groove 1801. An air passage is provided inside the air ring 1810. The air passage is connected to the air inlet of the air inlet pipe 1806. An air pump 1812 is installed in the mounting frame 1. The air pump 1812 is connected to the air ring 1810 through an air supply pipe 1811.

[0043] The probes of the test socket need to form a tight electrical connection with the wire harness terminals. Contaminants such as dust, oil, and metal oxide layers can form an insulating layer or a high-resistance layer between the probes and terminals, affecting the test results.

[0044] Before the control panel 5 controls the mechanical gripper 15 to insert the wire harness terminal into the detection socket 16, the control panel 5 controls the first micro motor 1802 and the air pump 1812 to start. Initially, the nozzle 1807 is located at the center of the detection socket 16. After the first micro motor 1802 starts, it drives the drive gear 1803 to rotate. The drive gear 1803, through gear meshing, drives the driven gear ring 1804 to rotate. As the driven gear ring 1804 rotates, it drives the air intake pipe 1806 to move outward along the air pipe groove 1805, and the air is released. The nozzle 1807 moves outward synchronously, while the air pump 1812 delivers gas to the nozzle 1807 through the air supply pipe 1811, air ring 1810 and air inlet pipe 1806. As the nozzle 1807 moves outward, it simultaneously sprays gas to purge the detection socket 1809 and remove impurities. The gas carries the impurities and flows towards the bottom of the detection socket 1809. By cleaning the detection socket 1809 with gas, contaminants are removed, ensuring the reliability of the electrical connection, thereby ensuring the accuracy and reliability of the test results.

[0045] The connection between the intake pipe 1806 and the driven gear ring 1804 is hinged.

[0046] When the driven gear ring 1804 drives the intake pipe 1806 to move, the angle of the intake pipe 1806 relative to the driven gear ring 1804 will change due to the limiting effect of the air pipe groove 1805. The hinge can ensure that the driven gear ring 1804 drives the intake pipe 1806 to move normally and avoid jamming.

[0047] The 1807 nozzle is dual-headed, meaning it sprays air from both the top and bottom simultaneously. This effectively prevents suspended particles in the air from naturally settling into the cleaned socket during the insertion and removal process, forming an air curtain to prevent the clean socket from being contaminated by the air.

[0048] like Figures 3-5 As shown, the sewage discharge assembly 19 includes a conical shell 1901, a filter screen 1902, a motor base 1903, a cleaning scraper 1904, a second micro motor 1905, a rotating rod 1906, a sealing block 1907, a threaded slide 1908, a limiting block 1909, a connecting block 1910, a negative pressure pipe 1911, and a sewage discharge tank 1912;

[0049] A conical shell 1901 is installed below the mounting base 1808. A filter screen 1902 is installed inside the conical shell 1901. A motor base 1903 is installed at the lower end of the conical shell 1901. A second micro motor 1905 is installed on the motor base 1903. A rotating rod 1906 is installed on the output shaft inside the second micro motor 1905. A sealing block 1907 is slidably connected to the rotating rod 1906. A connecting block 1910 is installed on the sealing block 1907. A cleaning scraper 1904 is installed on the 1910, a threaded groove 1908 is opened on the motor base 1903, a limiting block 1909 is set on the sealing block 1907, the limiting block 1909 is embedded in the threaded groove 1908, a negative pressure pipe 1911 is installed on the air supply pipe 1811, the negative pressure pipe 1911 connects the air supply pipe 1811 and the cavity between the filter screen 1902 and the conical shell 1901, and a sewage discharge groove 1912 is opened on the motor base 1903.

[0050] The sealing block 1907 is an inverted cone shape that is narrower at the top and wider at the bottom. The connecting block 1910 and the sealing block 1907 are slidably connected in the vertical direction, that is, the connecting block 1910 can slide up and down relative to the sealing block 1907, but cannot slide horizontally relative to it. The cleaning scraper 1904 is attached to the filter screen 1902.

[0051] The upper and lower ends of the threaded groove 1908 are both annular grooves parallel to the middle spiral section. The lower end of the sealing block 1907 is connected to the motor base 1903 through the tightening spring 1913.

[0052] The negative pressure pipe 1911 is a one-way gas pipe, and gas can only flow from the negative pressure pipe 1911 to the gas delivery pipe 1811;

[0053] When the air pump 1812 supplies air to the air inlet pipe 1806, the air flow in the air supply pipe 1811 creates a negative pressure in the negative pressure pipe 1911, which creates suction on the cavity between the filter screen 1902 and the conical shell 1901. This prevents backflow of impurities caused by the gas above the mounting base 1808, and facilitates better exhaust of gas from below. In the initial state, the sealing block 1907 blocks the lower port of the conical shell 1901, which can prevent external impurities from entering from below. When air passes through the filter screen 1902, impurities will adhere to the filter screen 1902. Clean air enters the jet nozzle 1807 with the clean gas from the air pump 1812 for cleaning.

[0054] A pressure detector is installed inside the negative pressure pipe 1911. When too many impurities accumulate on the filter screen 1902, forming a filter cake, the gas flow is obstructed. At this time, the pressure detector detects an increase in the air pressure in the negative pressure pipe 1911 and sends an electrical signal to start the second micro motor 1905. The second micro motor 1905 drives the sealing block 1907 to rotate through the rotating rod 1906. During rotation, the limiting block 1909 is limited by the threaded slide groove 1908. The sealing block 1907 is driven by the limiting block 1909 to slide downward along the threaded slide groove 1908. When the limiting block 1909 slides to the bottom of the threaded slide groove 1908, it rotates within the threaded slide groove 1908. When the sealing block 1907 rotates, it drives the cleaning scraper 1904 through the connecting block 1910 to clean the accumulated impurities on the filter screen 1902.

[0055] After cleaning, the second micro motor 1905 reverses, causing the sealing block 1907 to reset and seal.

[0056] When the sealing block 1907 moves down, the sealing block 1907 will no longer block the area below the conical shell 1901. The debris cleaned by the cleaning scraper 1904 will be discharged from below the conical shell 1901 and discharged from the drain trough 1912 along the inclined surface of the sealing block 1907.

[0057] When the sealing block 1907 is blocking and sealing the lower end of the conical shell 1901, the top spring 1913 is in an extended state and exerts a downward pressure on the sealing block 1907. When the second micro motor 1905 drives the sealing block 1907 to move downward, the top spring 1913 exerts a downward pulling force on the sealing block 1907, so that the limit block 1909 can smoothly move the spiral section of the spiral groove downward.

[0058] The upper and lower ends of the threaded groove 1908 are both annular grooves parallel to the middle spiral section. The lower parallel section ensures that the rotation of the sealing block 1907 and the rotation and cleaning of the cleaning scraper 1904 are not affected when the sealing block 1907 moves down. The upper parallel section prevents the motor from not stopping in time and causing motion interference when the sealing block 1907 moves up.

[0059] Working principle of the invention:

[0060] When the inspection begins, the control panel 5 controls the conveyor 6 to transport the wire harness to be inspected. When the wire harness passes the vision detector 11, the vision detector 11 detects the position of the interface terminal and transmits the position information back to the control panel 5. Based on the feedback information, the control panel 5 controls the first slider 8 to slide along the first module slide bar and the second slider 10 to slide along the second module slide rail 9. The rotating cylinder 12 drives the support rod 13 to rotate, so that the mechanical claw 15 is suspended above the interface terminal. Then, the telescopic cylinder 14 is controlled to extend, driving the mechanical claw 15 to approach and grab the interface terminal. Subsequently, the interface terminal is inserted into the inspection socket 16, and the inspection instrument 4 is started to perform the inspection.

[0061] Vehicle wiring harnesses typically have multiple interface terminals. Therefore, the visual detector 11 and the mechanical gripper 15 work together to ensure the accurate connection and detection of multiple terminals, thereby achieving automatic and accurate feeding, improving detection efficiency and ensuring detection accuracy.

[0062] The probes of the test socket need to form a tight electrical connection with the wire harness terminals. Contaminants such as dust, oil, and metal oxide layers can form an insulating layer or a high-resistance layer between the probes and terminals, affecting the test results.

[0063] Before the control panel 5 controls the mechanical gripper 15 to insert the wire harness terminal into the detection socket 16, the control panel 5 controls the first micro motor 1802 and the air pump 1812 to start. In the initial state, the air nozzle 1807 is located at the center of the spatial detection socket 16. After the first micro motor 1802 starts, it drives the drive gear 1803 to rotate. The drive gear 1803 drives the driven gear ring 1804 to rotate through gear meshing. When the driven gear ring 1804 rotates, it drives the air intake pipe 1806 to move outward along the air pipe groove 1805. The nozzle 1807 moves outward synchronously, while the air pump 1812 delivers gas to the nozzle 1807 through the air supply pipe 1811, air ring 1810, and air inlet pipe 1806. As the nozzle 1807 moves outward, it simultaneously blows gas to purge the test socket and remove impurities. The gas carries the impurities and flows towards the bottom of the test socket 1809. By cleaning the test socket 1809 with gas, contaminants are removed, ensuring the reliability of the electrical connection and thus ensuring the accuracy and reliability of the test results.

[0064] When the air pump 1812 supplies air to the air inlet pipe 1806, the air flow in the air supply pipe 1811 creates a negative pressure in the negative pressure pipe 1911, which creates suction on the cavity between the filter screen 1902 and the conical shell 1901. This prevents backflow of gas above the mounting base 1808, which would cause impurities to flow back and facilitates better exhaust of gas from below. In the initial state, the sealing block 1907 blocks the lower port of the conical shell 1901, which can prevent external impurities from entering from below. When air passes through the filter screen 1902, impurities will adhere to the filter screen 1902. Clean air enters the jet nozzle 1807 with the clean gas from the air pump 1812 for cleaning, improving air filtration efficiency and ensuring gas flow.

[0065] When too many impurities accumulate on the filter screen 1902, forming a filter cake, the gas flow is obstructed. At this time, the air pressure detector detects an increase in the air pressure in the negative pressure pipe 1911. The air pressure detector sends an electrical signal to start the second micro motor 1905. The second micro motor 1905 drives the sealing block 1907 to rotate through the rotating rod 1906. During rotation, the limiting block 1909 is limited by the spiral groove. The sealing block 1907 is driven by the limiting block 1909 to slide down along the spiral groove. When the limiting block 1909 slides to the bottom of the spiral groove, it rotates in the spiral groove. When the sealing block 1907 rotates, it drives the cleaning scraper 1904 through the connecting block 1910 to clean the accumulated impurities on the filter screen 1902.

[0066] After cleaning, the second micro motor 1905 reverses, causing the sealing block 1907 to reset and seal.

[0067] When the sealing block 1907 moves down, the sealing block 1907 will no longer block the area below the conical shell 1901. The debris cleaned by the cleaning scraper 1904 will be discharged from below the conical shell 1901 and discharged from the drain trough 1912 along the inclined surface of the sealing block 1907.

[0068] When the sealing block 1907 is blocking and sealing the lower end of the conical shell 1901, the top spring 1913 is in an extended state and exerts a downward pressure on the sealing block 1907. When the second micro motor 1905 drives the sealing block 1907 to move downward, the top spring 1913 exerts a downward pulling force on the sealing block 1907, so that the limit block 1909 can smoothly move the spiral section of the spiral groove downward.

[0069] The upper and lower ends of the threaded groove 1908 are both annular grooves parallel to the middle spiral section. The lower parallel section ensures that the rotation of the sealing block 1907 and the rotation and cleaning of the cleaning scraper 1904 are not affected when the sealing block 1907 moves down. The upper parallel section prevents the motor from not stopping in time and causing motion interference when the sealing block 1907 moves up.

[0070] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
