Description

Technical Field

[0001] This invention belongs to the field of high-speed wire harness appearance defect detection technology, and in particular relates to an online detection device for high-speed wire harness appearance defects. Background Technology

[0002] High-speed wire harnesses, also known as high-speed data harnesses, refer to wire harnesses with high-speed data transmission capabilities. They are often used as an important component for high-speed data transmission between various electronic devices, such as computer peripherals, radio and communication equipment, and aerospace equipment.

[0003] In the production process of high-speed wire harnesses, it is necessary to inspect their appearance to determine whether there are defects such as protrusions, dents, or damage on their outer walls, preventing these defects from affecting the overall quality of the high-speed wire harness. Currently, existing online inspection devices for appearance defects in high-speed wire harnesses can only detect multiple defects in practical applications, but cannot pinpoint the exact location of the defects or mark them. This forces subsequent maintenance work to invest more effort in locating the defects, thus negatively impacting the convenience of subsequent maintenance. Therefore, we provide an online inspection device for appearance defects in high-speed wire harnesses to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide an online detection device for appearance defects in high-speed wire harnesses. By setting up detection, marking, and drying components, the device first operates the detection component to detect appearance defects on the main body. Then, a spur gear drives a gear ring to rotate, causing the first spray head to rotate and evenly spray paint onto the defective areas. Simultaneously, a turntable drives a connecting column to rotate, causing a magnetic rod to move back and forth within a spiral coil, generating an induced current that drives a ring-shaped heated metal mesh plate. A fan generates hot air to accelerate paint drying, preventing wet paint from contaminating other parts of the high-speed wire harness's outer wall, thus avoiding any impact on quality. The device automatically marks the defective areas, facilitating subsequent maintenance. This invention solves the problem that existing online detection devices for appearance defects in high-speed wire harnesses can only detect multiple defects but cannot pinpoint their exact locations or mark them. This forces subsequent maintenance work to invest more effort in locating the defects, negatively impacting the convenience of maintenance.

[0016] 2.

[0021] 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.

[0022] Example 1, please refer to Figure 1-12 This invention provides the following technical solution: an online detection device for appearance defects in high-speed wire harnesses, comprising a winding assembly 1, a straightening assembly 2 disposed on the winding assembly 1, a detection assembly 3 disposed on the top of the winding assembly 1 and located on one side of the straightening assembly 2, a marking assembly 4 disposed on the winding assembly 1 adjacent to the detection assembly 3, a driving assembly 5 disposed on the winding assembly 1, a triggering assembly 6 disposed on the winding assembly 1, a collecting assembly 7 disposed on the winding assembly 1 below the marking assembly 4, a drying assembly 8 disposed on the top of the collecting assembly 7, and a meter counting assembly 9 disposed on the top of the collecting assembly 7 and located on one side of the drying assembly 8; the winding assembly 1 is used for releasing and... The components include: a winding component for easy inspection of the high-speed wiring harness for visual defects; a straightening component 2 to keep the high-speed wiring harness straight during inspection; an inspection component 3 to detect visual defects in the high-speed wiring harness; a marking component 4 to mark the defects on the outer wall of the high-speed wiring harness with paint; a drive component 5 to provide power for the operation of the straightening component 2 and the marking component 4; a collection component 7 to recycle and reuse excess paint; a drying component 8 to dry the paint at the defects; a trigger component 6 to generate electricity using the power of the marking component 4 to provide power for heating the drying component 8; and a meter counting component 9 to record the location of defects for accurate subsequent locating and maintenance.

[0023] The winding assembly 1 includes a base 101, with first vertical plates 102 symmetrically fixedly connected to the top of the base 101. A release roller 103 is rotatably connected between the two first vertical plates 102. Second vertical plates 104 are symmetrically fixedly connected to the top of the base 101, and a winding roller 105 is rotatably connected between the second vertical plates 104. A high-speed wire harness is wound around the outer wall of the release roller 103, with one end of the high-speed wire harness away from the release roller 103 wound around the winding roller 105. A first motor 106 is fixedly connected to one side of one of the second vertical plates 104, and the output end of the first motor 106 is fixedly connected to the output shaft of the winding roller 105. The top of the base 101 is symmetrically fixedly connected to the first vertical plate 104. The third upright plate 107 is fixedly connected to the base 101. A guide horn tube 108 is fixedly connected through one side of the third upright plate 107. The two guide horn tubes 108 are arranged in opposite directions. A control box 109 is fixedly connected to the top of the base 101. The straightening assembly 2 includes a first L-shaped plate 201 fixedly connected to one side of one of the third upright plates 107. A first rotating shaft 202 distributed on the outside of the high-speed wire harness is symmetrically rotatably connected to the inner side of the first L-shaped plate 201. A first guide roller 203 in contact with the high-speed wire harness is fixedly connected to the end of the first rotating shaft 202. A worm gear 204 is fixedly connected to the outer wall of the first rotating shaft 202.

[0024] The operation process of this embodiment is as follows: First, the high-speed wire harness installed on the release roller 103 is passed through two symmetrically arranged guide horn tubes 108 in sequence, and then through two parallel first guide rollers 203 to ensure that the wire harness travels smoothly and without obstruction. Next, the starting end of the high-speed wire harness is firmly wound and fixed to the surface of the take-up roller 105 to prepare for the subsequent take-up operation. Then, by starting the first motor 106, the take-up roller 105 is driven to rotate at a uniform speed in a set direction, thereby gradually winding the high-speed wire harness neatly and tightly onto the take-up roller 105. By reasonably setting the structure of two guide horn tubes 108 with opposite orientations and symmetrical positions, it is effectively ensured that the high-speed wire harness will not have positional shifts or tension fluctuations during continuous winding due to the gradual decrease in the diameter of the wire on the release roller 103 and the gradual increase in the diameter of the wire on the take-up roller 105. This significantly enhances the stability of the system operation and provides a reliable guarantee for subsequent high-precision detection. At the same time, the two worm gears 204 are synchronously controlled to rotate at a predetermined speed, which in turn drives the two first guide rollers 203 to move in coordination through the first rotating shaft 202. The rotation direction of the first guide rollers 203 is opposite to the winding direction of the high-speed wire harness. This design allows the first guide rollers 203 to apply a moderate reaction force to the high-speed wire harness in the opposite direction to the winding direction, so that the high-speed wire harness section between the two guide horn tubes 108 is always kept taut and straight, effectively avoiding slack or vibration, and further improving the accuracy and reliability of the subsequent inspection process.

[0025] Example 2, please refer to Figure 1-12 This second embodiment is an improvement on the first embodiment as follows: the detection component 3 includes a first support plate 301 fixedly connected to the top of the base 101, a hexagonal frame 302 fixedly connected to the top of the first support plate 301, a mounting block 303 fixedly connected to the bottom of the hexagonal frame 302, two sets of first vertical plates 304 symmetrically fixedly connected to the top of the mounting block 303, a second guide roller 305 rotatably connected between the two first vertical plates 304 and in contact with the outer wall of the high-speed wire harness, a first CMOS camera 306 fixedly connected to the top of the mounting block 303 and located between the two second guide rollers 305, and a second CMOS camera 307 symmetrically fixedly connected to the inner wall of the hexagonal frame 302 and located above the two second guide rollers 305.

[0026] The marking component 4 includes a second L-shaped plate 401 fixedly connected to the top of the base 101. A first annular plate 402 is fixedly connected to the end of the second L-shaped plate 401. An annular groove 403 is formed on the inner wall of the first annular plate 402. A gear ring 404 is rotatably connected to the inner wall of the annular groove 403. A first annular tube 405 is fixedly connected to the inner wall of the gear ring 404. A plurality of first nozzles 406 are evenly connected to the outer wall of the first annular tube 405. A slot 407 communicating with the annular groove 403 is formed on the outer wall of the first annular plate 402. An annular guide groove 408 is formed on one outer side of the first annular plate 402. An arc-shaped plate 409 is slidably connected to the inner wall of the annular guide groove 408. A paint tank 410 is fixedly connected to one side of the arc-shaped plate 409. A first pump body is installed inside the paint tank 410. A through-type nozzle is fixedly connected to the output end of the first pump body. A conduit 411 extends to the outside of the paint tank 410 and is connected to the first annular pipe 405. A feed pipe 412 is connected to the top of the paint tank 410, and a solenoid valve 413 is installed on the outer wall of the feed pipe 412. The drive assembly 5 includes a second motor 501 fixedly connected to an inner side adjacent to the first L-shaped plate 201. A worm gear 502 is fixedly connected to the output end of the second motor 501. The worm gear 502 meshes synchronously with two worm wheels 204. A spur gear 503 is fixedly connected to the outer wall of the worm gear 502 and meshes with a gear ring 404. A turntable 504 is fixedly connected to the end of the worm gear 502. A connecting post 505 is fixedly connected to one side of the turntable 504 off-center. A first fixing plate 506 located between the spur gear 503 and the turntable 504 is rotatably connected to the outer wall of the worm gear 502.

[0027] The operation process of this embodiment is as follows: By precisely controlling the simultaneous activation and collaborative operation of the first CMOS camera 306 and two second CMOS cameras 307, these three sets of cameras are stably installed on the periphery of the high-speed wire harness in a triangular layout structure. This ensures that the system can efficiently and from multiple angles quickly acquire and detect images of the outer surface of the wire harness as it continuously passes through the detection component 3. Based on the acquired image data, the system can analyze in real time whether there are appearance defects such as protrusions or depressions on the outer wall of the high-speed wire harness. Once a defect is identified on the surface of the high-speed wire harness, in the section where the high-speed wire harness continues to be transported to the marking component 4, the system first injects special marking paint with a clear contrast to the color of the high-speed wire harness body into the paint tank 410. Then, the first pump body is activated to stably pump the paint into the first annular pipe 405. Finally, the paint is precisely sprayed onto the defect location on the outer wall of the high-speed wire harness through the first nozzle 406, thereby completing the clear marking of the defect area.

[0028] Simultaneously, by controlling the second motor 501 to drive the worm 502 to rotate, the worm 502 meshes with the two worm wheels 204 to achieve synchronous and unidirectional rotation of the two worm wheels 204, providing a stable and reliable power output for the system. During this process, the worm 502 also drives the spur gear 503 to rotate, and the spur gear 503 meshes with the gear ring 404, thereby driving the gear ring 404, the first annular tube 405, and the first nozzle 406 to rotate as a whole. With the help of the continuously rotating first nozzle 406, the paint can be evenly and continuously sprayed on the outer surface of the high-speed wire harness, which not only improves the uniformity of the marking coverage but also significantly enhances the visual recognition effect of the defect marking.

[0029] Example 3, please refer to Figure 1-12 This embodiment three is an improvement on the first embodiment as follows: the triggering component 6 includes a second support plate 601 fixedly connected to the top of the base 101, a first support plate 602 fixedly connected to the top of the second support plate 601, the first support plate 602 being fixedly connected to the first fixing plate 506, a spiral coil 603 fixedly connected to the top of the first support plate 602, a guide rod 604 symmetrically fixedly connected to the first support plate 602, a baffle 605 fixedly connected to the top of the guide rod 604; an ear plate 606 is slidably connected to the outer wall of the guide rod, a rectangular frame 607 slidably sleeved on the connecting post 505 is fixedly connected between the two ear plates 606, an extension rod 608 is fixedly connected to the bottom of the rectangular frame 607, and a magnetic rod 609 that is inserted and engaged with the spiral coil 603 is fixedly connected to the bottom of the extension rod 608.

[0030] The collection assembly 7 includes a third support plate 701 fixedly connected to the top of the base 101, a second support plate 702 fixedly connected between the two third support plates 701, a collection box 703 fixedly connected to the top of the second support plate 702, a collection pipe 704 connected to the top of the collection box 703, an arc-shaped collection box 705 fixedly sleeved on the outer wall of the collection pipe 704, a connecting plate 706 fixedly connected between the arc-shaped collection box 705 and the second L-shaped plate 401, a conveying pipe 707 adapted to the feed pipe 412 connected to one outer side of the collection box 703, a second pump body inside the collection box 703, and the output end of the second pump body fixedly connected to the conveying pipe 707.

[0031] The drying assembly 8 includes a second fixing plate 801 fixedly connected to the top of the second tray 702. A second annular plate 808 is fixedly connected to the top of the second fixing plate 801. A second annular tube 802 is fixedly connected to the inner wall of the second annular plate 808. A plurality of second nozzles 803 are uniformly connected to the outer wall of the second annular tube 802. An L-shaped top plate 804 is fixedly connected to one side of the second fixing plate 801. A fan 805 is fixedly connected to the top of the L-shaped top plate 804. An air supply pipe 806 is fixedly connected to the output end of the fan 805. The air supply pipe 806 passes through the second annular plate 808 and is connected to the second annular tube 802. An annular heating metal mesh plate 807 is fixedly connected to the inner wall of the air supply pipe 806. The annular heating metal mesh plate 807 is connected to the spiral coil 603 by a wire.

[0032] The operation process of this embodiment is as follows: Excess paint sprayed on the high-speed wire harness will flow downward along the equipment structure and eventually collect in the arc-shaped collection box 705. Subsequently, the paint is further introduced into the collection tank 703 for temporary storage through the connected collection pipe 704. When the amount of paint in the collection tank 703 reaches a certain amount, the system will start the second pump to pump the accumulated paint back to the paint tank 410 (during this process, the delivery pipe 707 needs to be manually connected to the feed pipe 412), thereby realizing the effective recycling and reuse of paint. This process significantly reduces paint waste, while reducing production costs and improving resource utilization efficiency. On the other hand, the system drives the turntable 504 to rotate by controlling the rotation of the worm gear 502. The movement of the turntable 504 further drives the connecting column 505 to perform circular motion. During the rotation of the connecting column 505, it drives the rectangular frame 607 to move up and down reciprocally. The movement of the rectangular frame 607 is transmitted to the magnetic rod 609 through the extension rod 608, causing it to continuously move up and down reciprocally inside the spiral coil 603. The movement of the magnetic rod 609 causes the spiral coil 603 to continuously cut the magnetic field lines, thereby generating an induced current. The generated current is transmitted to the annular heating metal mesh plate 807 through the wire, causing it to heat up.

[0033] After the high-speed wire harness is coated at the defects on its outer wall, it is transported to the drying assembly 8 for processing. The system controls the fan 805 to start, accelerating the surrounding airflow. The air is heated as it flows through the annular heated metal mesh plate 807, forming a stable hot airflow. The hot air is blown directionally onto the painted surface of the high-speed wire harness through the second nozzle 803, significantly accelerating the drying speed of the paint. This measure effectively prevents undried paint from contaminating the outer wall of other parts of the high-speed wire harness during the winding process, thus ensuring the overall quality and appearance consistency of the high-speed wire harness.

[0034] Example 4, please refer to Figure 1-12This fourth embodiment is an improvement on the first embodiment as follows: the meter counting component 9 includes a pad 901 fixedly connected to the top of the second support plate 702, a U-shaped plate 902 fixedly connected to the top of the pad 901, a second rotating shaft 903 rotatably connected between the two inner sides of the U-shaped plate 902, a roller 904 in contact with the high-speed wiring harness fixedly connected to the outer wall of the second rotating shaft 903, a meter counter 905 fixedly connected to one outer side of the U-shaped plate 902, the output end of the meter counter 905 fixedly connected to the second rotating shaft 903, and a color collector 906 fixedly connected to the top of the U-shaped plate 902; a PLC controller is installed inside the control box 109, and the PLC controller is electrically connected to the first motor 106, the second motor 501, the solenoid valve 413, the first pump body, the second pump body, the first CMOS camera 306, the second CMOS camera 307, the fan 805, the meter counter 905, and the color collector 906 through wires.

[0035] The operation process of this embodiment is as follows: When the high-speed wire harness stably passes through the metering component 9 in a precise production process, its outer wall is in continuous contact with the roller 904 in the component, and the roller 904 is driven to rotate smoothly by friction. The rotational motion of the roller 904 is transmitted to the output shaft of the meter counter 905 through a mechanical connection, so that it rotates synchronously, thereby realizing the accurate measurement of the winding length of the high-speed wire harness. At the same time, the color acquisition instrument 906 installed next to the component performs high-precision acquisition of the marked color areas on the surface of the high-speed wire harness in real time, accurately identifies the color information, and synchronously records the specific position coordinates of each mark. This series of coordinated working processes provides an important basis and convenience for quickly and accurately locating the defect marks when maintaining and inspecting the high-speed wire harness in the future.
