Description

Technical Field

[0001] This invention relates to the field of wiring harness testing technology, and more specifically to an automotive wiring harness testing device. Background Technology

[0002] Automotive wiring harnesses are crucial components that ensure the efficient transmission of electrical energy and signals within a vehicle. Their main structure includes bundled wires and multiple connectors at the ends. To ensure the stability of their electrical and mechanical performance, comprehensive testing of the appearance, electrical performance, and mechanical performance of automotive wiring harnesses is required before they are put into use.

[0003] For example, Chinese patent CN118654827B discloses a wiring harness testing device for new energy vehicles. This device, by setting a pre-treatment mechanism, washes and dissolves the dust and dirt attached to the wiring harness, allowing for a faster and more intuitive assessment of the wiring harness's sealing performance, and greatly reducing the time required to disassemble the wiring harness onto different testing instruments.

[0004] However, automotive wiring harnesses require multiple tests, and both this equipment and the currently commonly used testing methods require removing the wiring harnesses to be tested first, placing the subsequent wiring harnesses on the testing table, and then they can be tested, which results in low testing efficiency.

[0005] Based on this, the present invention designs an automotive wiring harness testing device to solve the above problems. Summary of the Invention

[0012] Furthermore, the moving module includes a hydraulic cylinder, a guide rail, and a moving plate.

[0017] Compared to existing technologies, the advantages of this invention are as follows: After the operator removes the tested wire harness, they place it on the wire harness support platform, connecting the wire harness connector to the movable support module. Then, the striking module causes the floating support plate to vibrate on the moving end of the conveying mechanism, thereby causing the wire harness to vibrate through the wire harness support platform and the movable support module, achieving vibration testing of the wire harness. The conveying mechanism then moves the wire harness to the testing station via the floating support plate, the wire harness support platform, and the movable support module. At the testing station, the electrical testing module moves, connecting with the conductive module on the movable support module, and then the clamping module clamps the wire harness. First, the movable support module moves the wire harness connector to perform a pull-out force test on the connector, holding the position for a certain time (e.g., 30 seconds), after which the movable support module resets. Then, an external electrical testing device is activated, connecting the wire harness to the device via the electrical testing module, continuity module, and movable support module. The device then tests the electrical performance of the wire harness. During this process, the wire harness becomes conductive. The wire harness support platform and clamping module, in conjunction with the insulation testing module, detect any leakage current in the wire harness. Simultaneously, loading / unloading and vibration testing of the wire harness are performed at the loading / unloading station on the other side of the machine, thus improving testing efficiency.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0023] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 An automotive wiring harness testing device includes a machine base 1 and a testing mechanism 4. The two sides of machine 1 are symmetrically set as loading and unloading stations, and the middle of machine 1 is set as an inspection station.

[0024] The machine base 1 is equipped with a conveying mechanism 2, and the moving end of the conveying mechanism 2 is equipped with two sets of wire harness support mechanisms 3 for supporting and fixing the wire harness. like Figure 2 As shown, the wire harness support mechanism 3 includes a floating support plate 31, a wire harness support platform 32, and a movable support module 33; the floating support plate 31 is installed on the moving end of the conveying mechanism 2, the wire harness support platform 32 for supporting and fixing the wire harness is installed on the floating support plate 31, and multiple sets of movable support modules 33 for connecting and fixing the connectors of the wire harness are installed on the floating support plate 31. like Figure 3 As shown, the testing mechanism 4 includes a continuity module 41, an electrical testing module 42, a clamping module 43, an insulation testing module 44, and a striking module 45. The continuity module 41 is installed on the movable support module 33 and the floating support plate 31. The electrical testing module 42 is located on the lower side of the machine base 1 and is connected to the wire harness line through the continuity module 41, the movable support module 33, and the wire harness connector. The clamping module 43 is installed on the upper side of the machine base 1, and an insulation testing module 44 for performing insulation testing on the wire harness is installed on the clamping module 43. The electrical testing module 42 and the clamping module 43 are located at the testing station. The striking module 45 is installed on the machine base 1 at the loading and unloading station. The electrical testing module 42 is connected to external electrical testing equipment.

[0025] In this embodiment, when the automotive wiring harness testing equipment is working normally, at the loading and unloading station on one side, the operator takes out the tested wiring harness and places it on the wiring harness support platform 32, connecting the wiring harness connector to the movable support module 33. Then, the striking module 45 drives the floating support plate 31 to vibrate on the moving end of the conveying mechanism 2, thereby causing the wiring harness to vibrate through the wiring harness support platform 32 and the movable support module 33, achieving vibration testing of the wiring harness. Then, the conveying mechanism 2 moves the wiring harness to the testing station through the floating support plate 31, the wiring harness support platform 32, and the movable support module 33. At the testing station, the electrical testing module 42 moves, connecting the electrical testing module 42 to the conductive module 41 on the movable support module 33. Then, the clamping module 43 clamps the wire harness. At this time, the movable support module 33 moves the wire harness connector to perform a pull-out force test on the wire harness connector, which is held for a certain period of time, such as thirty seconds, and then the movable support module 33 resets. At this time, the external electrical testing equipment is started, and the wire harness is connected to the external electrical testing equipment through the electrical testing module 42, the conduction module 41 and the movable support module 33. The electrical performance of the wire harness is tested by the external electrical testing equipment. During this process, the wire harness is conductive. The wire harness support platform 32 and the clamping module 43 work together with the insulation testing module 44 to detect whether there is leakage in the wire harness. During this process, the loading and unloading of the wire harness and vibration testing are carried out simultaneously at the loading and unloading station on the other side of the machine 1, thereby improving the testing efficiency.

[0026] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figure 2 As shown, the conveying mechanism 2 includes a guide rail 21, a transmission assembly 22, a conveying motor 23, a positioning baffle 24, and a moving frame 25. The guide rail 21 is symmetrically and fixedly installed on the machine base 1, and the moving frame 25 is slidably connected to the guide rail 21 on both sides. The conveying motor 23 is fixedly installed on the lower side of the machine base 1, and the output end of the conveying motor 23 is fixedly connected to the power input end of the transmission assembly 22. The moving frame 25 is fixedly connected to the power output end of the transmission assembly 22. Positioning baffles 24 for positioning the moving frame 25 are symmetrically and fixedly installed on the machine base 1. The transmission assembly 22 is a synchronous belt and synchronous pulley transmission structure. The power input end of the transmission assembly 22 is the synchronous pulley, and the power output end of the transmission assembly 22 is the synchronous belt. like Figure 6 and Figure 7 As shown, multiple sets of slide rods 311 are symmetrically fixedly installed on the lower side of the floating support plate 31. The slide rods 311 are slidably connected to the movable frame 25. A spring 312 is provided on the outer sleeve of the slide rod 311. One end of the spring 312 is fixedly connected to the floating support plate 31, and the other end of the spring 312 is fixedly connected to the movable frame 25. A conductive carrier plate 321 is fixedly installed on the wire harness support platform 32, and the conductive carrier plate 321 is provided with a conformal groove for limiting the wire harness. The movable support module 33 includes a movable module and a connecting module. The movable module is installed on the floating support carrier plate 31, and the connecting module is installed on the movable end of the movable module. The moving module includes a hydraulic cylinder 331, a guide rail 332, and a moving plate 333. The hydraulic cylinder 331 is fixedly mounted on the floating support plate 31, and the guide rail 332 is fixedly mounted on the floating support plate 31.

The communication module includes a connector 334, which is fixedly mounted on a movable plate 333. The connector 334 has a slot 335 for engaging with a wire harness connector and a connection slot 336 for inserting with a wire harness connector.

[0027] In this embodiment, when the conveying mechanism 2 and the wire harness support mechanism 3 are working normally, the conveying motor 23 drives the moving frame 25 to move through the transmission component 22. The moving frame 25 moves horizontally under the limiting action of the guide rail 21 until the moving frame 25 contacts the positioning baffle 24. During this process, the two sets of floating support plates 31 on the moving frame 25 are moved alternately to the testing station. At the loading and unloading station, the wire harness is placed in the conformal groove on the conductive plate 321, and the wire harness plug is inserted into the connector 334 in sequence. Then, the striking module 45 is activated. The striking module 45 causes the floating support plate 31 to vibrate under the limiting action of the sliding rod 311 and the spring 312 on the lower side of the floating support plate 31 and the floating support action. This achieves the vibration test of the wire harness. Then, the conveying motor 23 drives the moving frame 25 to move through the transmission component 22, thereby moving the wire harness to the testing station through the floating support plate 31 and the wire harness support platform 32. At the testing station, the electrical testing module 42 lifts the floating support plate 31 upwards. At this time, the electrical testing module 42 is connected to the wire harness through the conduction module 41 and the connector 334. The clamping module 43 clamps the wire harness, and then the hydraulic cylinder 331 drives the moving plate 333 to move horizontally under the limiting action of the guide rail 332, thereby driving the wire harness connector to move through the connector 334. The hydraulic cylinder 331 applies a constant tensile force for thirty seconds, and then the hydraulic cylinder 331 drives the moving plate 333 and the connector 334 to reset, thereby driving the wire harness connector to reset, completing the pull-out force test.

Multiple lower connecting blocks 425 are fixedly installed on the first guide rods 424, and the lower connecting blocks 425 are aligned with the upper connecting block 412. The lower connecting blocks 425 are electrically connected to external electrical testing equipment. The clamping module 43 includes an upper support frame 431, a cylinder 432, a second guide rod 433, a third movable plate 434, and a pressure plate 435. The upper support frame 431 is fixedly installed on the machine base 1. The cylinder 432 is fixedly installed on the upper support frame 431. The third movable plate 434 is fixedly installed at the output end of the cylinder 432. Multiple second guide rods 433 are symmetrically fixedly installed on the third movable plate 434. The second guide rods 433 are slidably connected to the upper support frame 431. The pressure plate 435 is fixedly installed on the lower side of the third movable plate 434. The pressure plate 435 has a conformal groove that matches the wire harness. The pressure plate 435 is made of conductive metal. The insulation detection module 44 includes a multimeter 441, a first connecting plate 442, and a second connecting plate 443. The multimeter 441 is fixedly mounted on a third movable plate 434. The first connecting plate 442 is symmetrically mounted on the third movable plate 434. The multimeter 441 is electrically connected to the first connecting plate 442. The second connecting plate 443 is symmetrically mounted on a conductive carrier plate 321. The second connecting plate 443 is aligned with the first connecting plate 442. The striking module 45 includes a striking motor 451, a striking plate 452, and an extension plate 453. The striking motor 451 is fixedly installed on the machine base 1, the striking plate 452 is fixedly installed at the output end of the striking motor 451, and the extension plate 453 is fixedly installed on the side of the floating support plate 31.

[0029] In this embodiment, when the conduction module 41, electrical detection module 42, clamping module 43, insulation detection module 44, and striking module 45 are working normally, after the wire harness is loaded at the loading and unloading station, the striking motor 451 is started to drive the striking plate 452 to rotate, and the striking plate 452 strikes the extension plate 453 on the floating support plate 31; under the limiting of the sliding rod 311 and the spring 312 on the lower side of the floating support plate 31, the floating support plate 31 vibrates; thus realizing the vibration test of the wire harness. At the testing station, hydraulic cylinder 422 on the lower support frame 421 drives moving plate 423 to move vertically under the limiting action of guide rod 424, thereby driving lower connecting block 425 on guide rod 424 to move vertically until lower connecting block 425 contacts upper connecting block 412. At this time, external electrical testing equipment is electrically connected to the wire harness through lower connecting block 425, upper connecting block 412, conductive plate 411, and connector 334. Cylinder 432 drives moving plate 434 to move, and moving plate 434 moves vertically under the limiting action of guide rod 433, thereby driving pressure plate 435 to move vertically. The wire harness is pressed by the conformal groove on the lower side of pressure plate 435. The full contact of the wire harness is achieved through the cooperation of pressure plate 435 and conductive carrier plate 321. After passing the pull-out force test, external electrical testing equipment is started to test the electrical performance of the wire harness. Simultaneously, when the pressure plate 435 presses the wire harness, the connecting plate 442 on the moving plate 3 434 and the connecting plate 443 on the conductive carrier plate 321 come into contact; the wire harness is conductive, and if the outer insulation of the wire harness fails, the current will flow into the multimeter 441 through the conductive carrier plate 321, the tapping plate 452, the connecting plate 442 and the connecting plate 443; the multimeter 441 can be used to detect whether there is leakage in the wire harness.
