Description

Technical Field

[0001] The present invention relates to the technical field of wire harness detection, and in particular to a wire harness detection device for new energy vehicles. Background Art

[0002] New energy vehicle wiring harness refers to the general term for wires and connectors used in the electronic control system of new energy vehicles; it is an important component of new energy vehicles, responsible for transmitting signals, data and energy, and used to control all systems of new energy vehicles; the manufacturing technology and quality level of new energy vehicle wiring harnesses directly affect the performance, safety and reliability of new energy vehicles.

[0003] In order to ensure the quality and reliability of new energy vehicle wiring harnesses, strict inspection and testing are required; the inspection content includes the electrical performance, mechanical performance, environmental adaptability and other aspects of the wiring harness to ensure that the wiring harness can work normally under various conditions and meet the performance and safety requirements of the vehicle.

[0004] Patent application number CN202310469359.2 discloses a wiring harness detection device for new energy vehicles. The first detection mechanism of the invention drives the two lower pads to slide in different directions through the first motor to straighten the wiring harness. The second detection mechanism drives the polishing belt through the driving cylinder to lift the wiring harness upward, so as to observe whether there are small transverse cracks on the sheath of the wiring harness. The second detection mechanism drives the polishing belt to move radially along the wiring harness through the second motor at the same time, and the third motor drives the polishing belt to move transversely, which is used to test the wear resistance of the wiring harness sheath. At the same time, the transverse cracks, radial cracks and oblique cracks of the wiring harness sheath are more obvious. Then, the first detection mechanism continues to drive the two lower pads to slide and pull the wiring harness in different directions through the first motor to test the tensile strength of the wiring harness according to the test requirements.

DETAILED DESCRIPTION

[0034] In order to make the purpose, 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. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

[0035] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. When a mechanism is referred to as being "fixed to" another mechanism, it may be directly on the other mechanism or there may also be a centered mechanism. When a mechanism is considered to be "connected to" another mechanism, it may be directly connected to the other mechanism or there may be a centered mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it may be directly set on the other mechanism or there may be a centered mechanism at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0036] like Figures 1 to 9 As shown, the present invention is a wire harness detection device for new energy vehicles, comprising: a detection platform 1, a wire clamping claw 2 for clamping the wire harness, a moving mechanism 3 for driving the wire clamping claw 2 to move inside the detection platform 1; a pretreatment mechanism 4 for cleaning the surface of the clamped wire harness, and a detection mechanism 5 for detecting the cleaned wire harness;

[0037] The staff straightens the wire harness and fixes it inside the testing table 1 through the wire clamping claw 2. The wire clamping claw 2 then moves along the guide groove 34 driven by the moving mechanism 3, thereby moving the clamped wire harness to the pretreatment mechanism 4 and the testing mechanism 5 respectively, and the cables are first cleaned and then tested. It should be noted here that the clamping method of the wire clamping claw 2 for clamping the wire harness is a prior art, so it will not be elaborated here.

[0038] The moving mechanism 3 is composed of a motor 31, a threaded rod 32, a threaded sleeve 33, and a guide groove 34; the motor 31 is fixedly installed on the detection platform 1; the output shaft of the motor 31 is fixedly connected to the threaded rod 32; the threaded sleeve 33 is threadedly connected to the threaded rod 32; the guide groove 34 is provided on the back plate of the detection platform 1; the wire clamping claw 2 passes through the threaded sleeve 33 and is slidably installed in the guide groove 34; when the wire clamping claw 2 clamps the wire harness, the motor 31 is started, and the threaded rod 32 fixedly connected to the output shaft of the motor 31 rotates accordingly, and the threaded sleeve 33 rotates and moves axially along the threaded rod 32. Since the wire clamping claw 2 passes through the threaded sleeve 33 and is slidably installed in the guide groove 34, when the threaded sleeve 33 moves axially along the threaded rod 32, the wire clamping claw 2 will slide along the guide groove 34 under the push of the threaded sleeve 33.

[0039] It should be noted here that the guide groove 34 is divided into a detection groove 341 and a cleaning groove 342. The detection groove 341 is a straight groove parallel to each other, and the cleaning groove 342 is a gradually approaching inclined groove. When the wire clamping claw 2 is driven by the moving mechanism 3, it will first slide along the cleaning groove 342. Since the cleaning groove 342 is a gradually approaching inclined groove, the wire clamping claw 2 will gradually approach when sliding downward in the cleaning groove 342. Since the wire harness between the two wire clamping claws 2 is in a straightened state during the installation stage, when the wire clamping claws 2 gradually approach, the originally straightened wire harness will gradually bend downward in an arc shape, so that the wire harness can be immersed in the water tank 41.

[0040] The pretreatment mechanism 4 includes: a water tank 41 for soaking the wire harness, a dust baffle 42 slidably installed on the mouth of the water tank 41; a cleaning component for wiping and cleaning the soaked wire harness; when the wire harness needs to be pre-treated before detection, the wire clamping claws 2 will slide along the cleaning groove 342 under the drive of the moving mechanism 3, so that the wire harness between the two wire clamping claws 2 is in an arc shape until it is immersed in the water tank 41; it has the effect of flushing and dissolving the dust and stains attached to the wire harness; and then the water stains and stains on the soaked wire harness are finally wiped by the subsequent cleaning component to achieve a better cleaning effect and improve the accuracy of subsequent detection.

[0041] It should be added that the sealing detection assembly includes: a sealing chamber 56 fixedly mounted on one side of the detection platform 1, through which the wiring harness passes; an air pump for filling the sealing chamber 56 with high-pressure gas; when the wiring harness is immersed in the water tank 41, the wiring harness that is not immersed in water is passed through the sealing chamber 56, and the high-pressure air pump fills the sealing chamber 56 with gas to make the sealing chamber 56 in a high-pressure state;

[0042] Since the wiring harness passes through the sealing chamber 56, if there are gaps in the wiring harness sheathing and the sealing effect is poor, the airflow will pass through the cracks in the wiring harness sheathing under the influence of high pressure and flow out in the interlayer between the wiring harness sheathing and the wire core. If there are also cracks on the wiring harness immersed in water, the airflow will pass through the cracks to form tiny bubbles on the surface of the wiring harness. These bubbles will adhere to the wiring harness and continue to be generated with the leaking airflow. Therefore, the airtightness of the wiring harness can be detected by observing whether bubbles are generated in the wiring harness immersed in the water tank 41. It should be noted here that the water tank 41 is a water tank 41 made of transparent material.

[0043] By immersing the wiring harness in the water tank 41 through the above mechanism, not only can the dust and stains attached to the wiring harness be flushed and dissolved, but also the sealing performance of the wiring harness can be judged more quickly and intuitively by cooperating with the sealing assembly, thereby greatly reducing the time for disassembling the wiring harness to different testing instruments.

[0044] If the upper end of the water tank 41 is open and exposed, the inside of the water tank 41 will be covered with dust when not in use for a long time, and cleaning it when it is used again greatly increases the labor; and when in use, grinding residues from grinding the wire harness will fall into the water tank 41, which will increase the frequency of replacing the water in the water tank 41 and add unnecessary operating steps.

[0045] A driving assembly for moving the two dust baffles 42 away from each other as the clamping claw 2 moves downward along the guide groove 34; the driving assembly is composed of a slider 431 slidably mounted in the guide groove 34, a traction member 432, a fixed pulley 433 for changing the pulling direction of the traction member 432, and a scraping unit for scraping dust off the dust baffles 42 as the dust baffles 42 move;

[0046] One end of the traction member 432 is fixedly connected to the slider 431; the other end of the traction member 432 is fixedly connected to the dust shield 42; the middle part of the traction member 432 abuts against the fixed pulley 433;

[0047] The fixed pulley 433 is rotatably mounted on the side wall of the detection, and when the wire clamping claw 2 slides along the cleaning groove 342 through the above-mentioned mechanism, it will abut against the slider 431 slidably mounted in the guide groove 34, so that the slider 431 slides along the guide groove 34 with the wire clamping claw 2. It should be noted here that the slider 431 can only slide along the cleaning groove 342 in the guide groove 34; since the two ends of the traction member 432 are respectively fixedly connected to the slider 431 and the dust baffle 42, the dust baffle 42 is slidably mounted on the end of the water tank 41, and at the same time, by setting the fixed pulley 433, the slider 431 is pulled so as to adjust the force direction of the traction member 432 to a force direction that is convenient for the dust baffle 42 to move along the mouth of the water tank 41, so that when the wire clamping claw 2 moves along the cleaning groove When sliding downward, the slider 431 slides along the cleaning groove 342 with the wire clamping claw 2, and at the same time, the slider 431 pulls the dust baffle 42 to move toward each other along the mouth of the water tank 41 through the traction member 432, separating the two originally closed dust baffles 42, so that when the wire harness needs to be immersed in the water tank 41, the dust baffles 42 separate towards each other, so that the wire harness can just be immersed in the water tank 41. At the same time, when the immersed wire harness needs to be pulled out of the water tank 41, the wire clamping claw 2 slides in the opposite direction along the cleaning groove 342. At this time, the wire clamping claw 2 no longer presses the slider 431 downward, so that the dust baffle 42 is elastically connected to the side wall of the detection table 1 through a spring 435, causing the separated dust baffles 42 to move toward each other under the elastic force of the spring 435 until they are reset.

[0048] When the clamping claw 2 moves downward along the cleaning groove 342, it presses down the slider 431, so that the slider 431 pulls the traction member 432. Under the action of the fixed pulley 433 changing the pulling direction, the traction member 432 pulls the dust shield 42 to move to both sides of the water tank 41, so as to open the water tank 41 and immerse the wire harness in the water tank 41.

[0049] Therefore, through the above-mentioned mechanism, when the wire harness needs to be cleaned, the dust shield on the upper end of the water tank 41 can be separated, and when the wire harness does not need to be cleaned, the dust shield on the upper end of the water tank 41 can be closed. This prevents the inside of the water tank 41 from being filled with dust when the water tank 41 is not used for a long time, and requires cleaning when it is used again, which greatly increases the labor.

[0050] It should be emphasized here that since the wire clamping claw 2 and the slider 431 are both slidably installed in the guide groove 34, when the spring 1 435 drives the dust baffle 42 to reset, since the slider 431 cannot pass through the wire clamping claw 2, it can only move with the wire clamping claw 2 and move closely with the slider 431; therefore, when the wire clamping claw 2 slides in the opposite direction along the cleaning groove 342, the spring 1 435 cannot reset the dust baffle 42 at one time but follows the wire clamping claw 2 to reset it upward continuously until it closes; thereby preventing the dust baffle 42 from closing too quickly and clamping the wire harness. It should be explained here that the spring 1 435 is always in a compressed state, so that the traction member is consistently in a straightened state, so that when the wire clamping claw 2 stops abutting against the slider 431, it can move upward along the guide groove 3434.

[0051] Since grinding debris will be generated when the wire harness is tested for wear resistance, manual cleaning is often required on a regular basis. The cleaning process may require downtime and waiting, further affecting production progress.

[0052] The scraping unit is composed of a rack 4341 fixedly mounted on the top of the dust baffle 42 and moving with the dust baffle 42, a linkage 4342 that rotates with the movement of the rack 4341, a rack 2 4343 that moves with the rotation of the linkage 4342, a dust scraper 4344 fixedly mounted on the top of the rack 2 4343, and a reset spring 4345 that drives the dust scraper 4344 to reset. The patent installs the wear resistance detection mechanism above the dust baffle 42, so that the debris generated when the wear resistance detection of the wiring harness is performed will fall onto the dust baffle 42 with gravity; when the dust baffle 42 separates toward each other, the rack 1 4341 fixedly mounted on the dust baffle 42 drives the linkage 4342 to rotate, and when the linkage 4342 rotates, the rack 2 4343 engaged therewith They move upward successively. Since the scraper plate 4344 is fixedly installed on the top of the rack 2 4343, when the rack 2 4343 moves upward, the scraper plate 4344 moves upward away from the surface of the dust baffle plate 42, so that when the dust baffle plate 42 covered with debris is separated, the scraper plate 4344 is lifted upward without scraping the debris on the dust baffle plate 42. When the dust baffle plate 42 covered with debris is closed towards each other, the rack 1 4341 cannot drive the linkage 4342 to rotate. At this time, the scraper plate 4344 is immediately reset under the action of the reset spring 4345. When the dust baffle plate 42 covered with debris is gradually closed towards each other, the scraper plate 4344 will gather and scrape the debris on the dust baffle plate 42, thereby saving time for manual scraping and will not affect the detection progress.

[0053] An ash guide plate 4346 is also provided above the ash baffle plate 42; the ash guide plate 4346 is fixedly connected to the side wall of the inspection platform 1; the debris generated by grinding can be concentrated onto the ash baffle plate 42 under the guidance of the ash guide plate 4346 through the ash guide plate 4346, so as to facilitate the centralized cleaning of the ash baffle plate 42.

[0054] It should be noted here that the specific working principle of the linkage 4342 can be referred to Figure 5 The linkage member 4342 includes: a linkage shaft 43421 rotatably mounted on the side wall of the detection platform 1, a linkage gear 43422 fixedly sleeved on the outer edge of the linkage shaft 43421 and meshing with the rack 2 4343, a ratchet 43423 fixedly sleeved on the end of the linkage shaft 43421, a toothed ring 43424 sleeved on the outer edge of the ratchet 43423 and meshing with the rack 1 4341, and a hingedly mounted on the toothed ring 43424. The inner wall of the pawl 43425 meshes with the ratchet 43423; when the dust guard plate 42 is separated from each other, the rack 4341 drives the gear ring 43424 to rotate counterclockwise, and the pawl 43425 hingedly mounted on the outer edge of the gear ring 43424 abuts against the ratchet 43423 when rotating counterclockwise with the gear ring 43424, thereby driving the ratchet 43423 to rotate, and when the ratchet 43423 rotates, it drives the interlocking gear 43422 to rotate synchronously; and the interlocking gear 4342 2 meshing rack 2 4343 moves up and down accordingly; when the ash baffle 42 is closed towards each other, rack 1 4341 drives toothed ring 43424 to rotate clockwise, and when toothed ring 43424 rotates clockwise, ratchet 43425 hingedly mounted on the outer edge of toothed ring 43424 will not abut against ratchet 43423 when it rotates counterclockwise with toothed ring 43424, so that when the ash baffle 42 is closed towards each other, ratchet 43423 does not rotate, but due to the provision of driving ash scraper 43 The reset spring 4345 of 44 is reset. The reset spring 4345 will give a downward force to the rack 2 4343. When the dust guard plates 42 are closed towards each other, the ratchet 43423 can rotate freely on the connecting shaft 43421. Then when the toothed ring 43424 rotates clockwise, the rack 2 4343 drives the connecting gear 43422 to rotate counterclockwise. The ratchet 43425 on the toothed ring 43424 cannot abut against the ratchet 43423, thereby causing no motion interference.

[0055] When the wire clamping claw 2 moves downward along the cleaning tank driven by the moving mechanism 3, it will abut against the slider 431 slidably installed in the cleaning tank, and the slider 431 will pull the ash baffle plate 42 to open along the opposite side of the water tank 41. When the ash baffle plate 42 is opened, the ash scraper plate 4344 will move upward, and will not scrape the debris generated during the last detection into the water tank 41. When the wire clamping claw 2 moves in the opposite direction to drive the wiring harness away from the water tank 41, the ash baffle plate 42 moves toward each other, and the reset spring 4345 drives the ash hanging plate to reset immediately, so that the ash scraper plate 4344 is close to the ash baffle plate 42. When the ash baffle plate 42 moves toward each other, the ash scraper plate 4344 can gather and scrape off the debris of the ash baffle plate 42; it should be explained here that the ash baffle plate 42 can not only block the water tank 41 from dust entering the water tank 41, thereby reducing the number of times the water tank 41 is cleaned, but also can collect and clean the waste chips generated during the detection, thereby greatly improving work efficiency and safety.

[0056] The cleaning assembly includes: a rack 3 441 fixedly mounted on the back plate of the detection platform 1; a gear 2 442 meshing with the rack 3 441; the gear 2 442 is coaxially connected with the threaded rod 2 443; a limiting groove 444 is provided on the threaded sleeve 33; the threaded rod 2 443 is rotatably mounted in the limiting groove 444; a cleaning member 445 threadedly connected to the threaded rod 2 443, and the cleaning member 445 is limited by the limiting groove 444; when the clamping claw 2 slides from the cleaning groove 342 to the detection groove 341 under the drive of the moving mechanism 3, and moves upward along the detection groove 341, it will make The gear 2 442 installed on the threaded sleeve 33 is rotatably engaged with the rack 3 441 installed on the back plate of the detection platform 1, thereby driving the threaded rod 2 443 to rotate. Since the cleaning member 445 is threadedly connected with the threaded rod 2 443, when the threaded rod 2 443 rotates, the cleaning member 445 moves along the limiting groove 444. Since the limiting groove 444 is opened in the direction of straightening the wire harness, when the cleaning member 445 moves along the limiting groove 444, the cleaning member 445 can wipe the wire harness along the straightening direction, further clean the water stains and impurities sticking on the wire harness, improve the cleaning effect, and enhance the subsequent detection effect.

[0057] The detection mechanism 5 includes: a sealing detection component for performing sealing detection on the wire harness, and a crack detection component for performing crack detection on the cleaned wire harness; the crack detection component includes: a linear module 52 fixedly mounted on the back plate of the detection platform 1, and a grinding roller 53 driven by the linear module 52; when the crack detection component is required for the wire harness, it is only necessary to move the wire clamping claw 2 to the grinding roller 53 through the moving mechanism 3, and the wire harness stretched between the two wire clamping claws 2 contacts the grinding roller 53. At this time, the wire clamping claw 2 continues to move upward, so that the grinding roller 53 pushes the stretched wire harness into an arc shape, and then the linear module 52 moves horizontally along the wire harness to lift up each part of the wire harness, so as to facilitate observation of whether there are fine cracks on the sheathing layer of the wire harness.

[0058] A second driving motor 54 is fixedly connected to the grinding roller 53. When the grinding roller 53 pushes the wire harness into an arc shape, the second driving motor is started to drive the grinding roller 53 to rotate. The grinding roller 53 grinds the wire harness transversely to test the wear resistance of the wire harness sheath.
