[0002] The IoT-based hardware testing equipment for electronic information engineering is an intelligent system that integrates IoT technology, multi-dimensional sensing technology, edge computing, artificial intelligence, and traditional electronic testing techniques. Its core objective is to solve problems in traditional hardware testing such as incomplete single-point testing, data lag, heavy reliance on manual labor, and difficulty in fault early warning. It enables full lifecycle monitoring, high-precision testing, intelligent fault diagnosis, and predictive maintenance of various hardware components (such as circuit boards, chips, industrial motors, and smart terminal modules) in the field of electronic information engineering, providing efficient and reliable testing support for scenarios such as electronic manufacturing, industrial production, and smart terminal R&D.

[0003] The core functions of electronic hardware devices rely on circuit boards. If a circuit board malfunctions, it can affect the performance of the device or even cause the system to crash.

Detailed Implementation

[0012] 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.

[0013] Example 1, please refer to Figures 1-3 This invention provides a technical solution: a hardware testing device for electronic information engineering based on the Internet of Things, comprising: The testing platform 1 has a loading platform 2 fixedly connected to its side, a unloading platform 4 fixedly connected to the side of the testing platform 1 away from the loading platform 2, a control panel 6 fixedly connected to the side of the unloading platform 4, a unloading component 5 fixedly connected to the top of the unloading platform 4, a testing head 8 fixedly connected to the middle of the top of the testing platform 1, and a conveyor belt 9 rotatably connected to the top of the testing platform 1, the loading platform 2 and the unloading platform 4, with placement grooves evenly opened on the conveyor belt 9. The feeding component 3 is used to feed circuit boards. The top of the feeding component 3 is fixedly connected to the top of the feeding table 2 and the top of the inspection table 1. Contact component 7 is used to perform contact cleaning work on the conveyor belt 9. The side of the contact component 7 is fixedly connected to the inner side of the inspection table 1. Please see Figure 4 The feeding component 3 includes a fixed frame 31. The two sides of the bottom of the fixed frame 31 are fixedly connected to the top of the detection table 1 and the feeding table 2. A transmission mechanism 32 is fixedly connected to the top of the fixed frame 31. A slider 33 is slidably connected to the top of the fixed frame 31. The slider 33 is connected to the output end of the transmission mechanism 32. A suction cup claw mechanism 34 is fixedly connected to the bottom of the slider 33. An air blowing mechanism 35 is fixedly connected to both sides of the slider 33. The suction cup claw mechanism 34 at the 2nd loading platform is activated to perform negative pressure suction and grip the circuit board on the platform to ensure that the board is stable and does not fall off. The suction cup claw mechanism 34 is fixedly connected to the slider 33. The transmission mechanism 32 drives the slider 33 to move in a direction along the fixed frame 31, thereby driving the attracted circuit board to be transported synchronously towards the detection table 1. As the slider 33 moves along the fixed frame 31 toward the test table 1, the slider 33 is linked to the air blowing mechanism 35 to start synchronously. The air blowing mechanism 35 sprays air into the area of ​​the conveyor belt 9 of the test table 1 to clean the surface of the circuit board that is about to be placed or is already on the conveyor belt 9, removing dust, debris and other impurities, and avoiding interference from foreign objects in subsequent testing. After the slider 33 drives the suction cup claw mechanism 34 to move to the designated position of the conveyor belt 9 of the inspection table 1, the suction cup claw releases the negative pressure and puts the circuit board into the placement groove of the conveyor belt 9. The placement groove limits and fixes the circuit board, completing the loading process and preparing for subsequent inspection. Please see Figure 5The air blowing mechanism 35 includes two piston rods 355 and two piston cylinders 357. A baffle 353 is fixedly connected to one end of each piston rod 355. A piston block 356 is fixedly connected to the end of each piston rod 355 away from the baffle 353. A slide rod 352 is slidably connected to the end of each piston rod 355 near the baffle 353. A connecting block 351 is fixedly connected to the other end of each slide rod 352. Both connecting blocks 351 are fixedly connected to both sides of the slider 33. The sides of the connecting blocks 351 are slidably connected to the inner side of the fixing frame 31. A sleeve is fitted on the slide rod 352. There is a first spring 354, one end of the first spring 354 is fixedly connected to the baffle 353, and the other end of the first spring 354 is fixedly connected to the side of the connecting block 351. The sides of the two piston cylinders 357 are fixedly connected to the inner side of the fixing frame 31. One end of the piston cylinder 357 is fixedly connected to an air cylinder 358. The air cylinder 358 is located above the conveyor belt 9 in the detection table 1. The bottom of the air cylinder 358 is evenly provided with air grooves 359. The sides of the piston rod 355 and the piston block 356 are slidably connected to the inner side of the piston cylinder 357. When the transmission mechanism 32 drives the slider 33 to move along the fixed frame 31 toward the detection table 1, it will synchronously drive the connecting blocks 351 on both sides of the slider 33 to move in the same direction. When the connecting block 351 moves, it will drive the slide rod 352 connected to it to move synchronously. At this time, the connecting block 351 will squeeze the first spring 354 sleeved on the slide rod 352. As the connecting block 351 continues to move, the slide rod 352 will slide into the piston rod 355. The connecting block 351 drives the piston rod 355 to move along the axis of the piston cylinder 357 through the slide rod 352 baffle 353. When the piston block 356 moves inside the piston cylinder 357, it compresses the gas inside the cylinder and forces it into the gas cylinder 358. Since the bottom of the air cylinder 358 is evenly provided with air grooves 359, the compressed gas can be evenly sprayed out through the air grooves 359 and directly act on the surface of the circuit board to be tested on the conveyor belt 9. The evenly distributed air grooves 359 can form an airflow covering the entire surface of the circuit board, avoiding cleaning dead corners, ensuring that dust, debris and other impurities are thoroughly blown away, preventing foreign objects from obstructing and interfering with signal acquisition during testing, and improving the accuracy and stability of test data. Example 2, please refer to Figure 6-7Based on Embodiment 1, the present invention provides a technical solution: the contact component 7 includes a bracket 71, the side of the bracket 71 is fixedly connected to the inner side of the detection table 1, the middle of the bracket 71 is fixedly connected to a contact shell 72, the bottom of the contact shell 72 is fixedly connected to a suction machine 75, the top of the suction machine 75 is fixedly connected to a mesh plate 76, the top of the mesh plate 76 is uniformly provided with wiping mechanisms 78, the top of the mesh plate 76 is fixedly connected to a collection shell 77, the top of the collection shell 77 is fixedly connected to a mesh plate 73, the sides of both the mesh plate 73 and the mesh plate 76 are fixedly connected to the inner side of the contact shell 72, and the top of the mesh plate 73 is slidably connected to a cleaning mechanism 74; When the conveyor belt 9 of the testing platform 1 is rotating normally, the cleaning mechanism 74 inside the contact housing 72 always keeps in contact with the side of the conveyor belt 9 and moves synchronously with the conveyor belt 9 to thoroughly clean the surface of the conveyor belt 9 and the opening placement groove. While the cleaning mechanism 74 is cleaning the side of the conveyor belt 9, the suction machine 75 is turned on. The negative pressure suction generated by the suction machine 75 when it is working sucks the impurities stripped off by the cleaning mechanism 74 into the collection housing 77, preventing the impurities from floating and spreading around the conveyor belt 9 and avoiding the problem of dust adhering to the circuit board again after cleaning. The suction generated by the aspirator 75 will drive the wiping mechanism 78 inside the collection housing 77 to rotate automatically; The rotating wiping mechanism 78 can make contact friction with the bottom of the first mesh plate 73 and the top of the second mesh plate 76 respectively, and clean the mesh holes of the two mesh plates in real time. To prevent impurities from clogging the mesh openings of mesh plate 1 73 and mesh plate 2 76, avoid ventilation problems caused by mesh blockage, and ensure that the negative pressure suction of the suction machine 75 remains stable. Impurities sucked into the collection shell 77 are intercepted between mesh plate 1 73 and mesh plate 2 76, achieving centralized collection of impurities; Please see Figure 8 The wiping mechanism 78 includes a wiping shaft 781, the top of which is rotatably connected to the bottom of the first mesh plate 73, the bottom of which is rotatably connected to the top of the second mesh plate 76, the top of the wiping rod 783 located above the wiping shaft 781 is in contact with the bottom of the first mesh plate 73, the bottom of the wiping rod 783 located below the wiping shaft 781 is in contact with the top of the second mesh plate 76, a guide vane 782 is fixedly connected to the middle of the side of the wiping shaft 781, and wiping rods 783 are fixedly connected to both the upper and lower sides of the wiping shaft 781. Square grooves 784 are evenly provided on the side of the wiping rods 783. When the inhaler 75 starts inhalation, the negative pressure it generates will cause the airflow inside the collection housing 77 to flow in a specific direction. When the airflow passes through the guide vane 782, it will transfer kinetic energy to the guide vane 782, driving the guide vane 782 to drive the wiping shaft 781 to rotate between the bottom of the first mesh plate 73 and the top of the second mesh plate 76; As the wiping shaft 781 rotates, it will simultaneously drive the wiping rods 783 on its upper and lower sides to rotate with the shaft; The wiping rod 783 has square grooves 784 evenly distributed on its side to enhance the friction cleaning ability; The upper wiping rod 783 contacts and rotates against the bottom of the mesh plate 73, which can scrape away the dust and debris clogging the mesh of the mesh plate 73 in real time, avoid the problem of poor ventilation caused by the mesh clogging, and ensure that the negative pressure suction of the suction machine 75 is always stably transmitted and the impurity collection efficiency does not decrease. The lower wiping rod 783 contacts and rotates with the top of the second mesh plate 76. Through continuous sweeping action, it prevents dust from accumulating locally on the surface of the second mesh plate 76 and reduces the risk of mesh plate deformation caused by excessive local dust accumulation. Please see Figure 9 The cleaning mechanism 74 includes a cleaning frame 741. Connecting shafts 742 are evenly arranged at the bottom of the cleaning frame 741. The top of the connecting shafts 742 is fixedly connected to the bottom of the cleaning frame 741. The bottom of the connecting shafts 742 is slidably connected to the top of the mesh plate 73. A second spring 743 is sleeved on the connecting shafts 742. The top of the second spring 743 is fixedly connected to the bottom of the cleaning frame 741. The bottom of the second spring 743 is fixedly connected to the top of the mesh plate 73. Cleaning cylinders 744 are rotatably connected to both sides of the top of the cleaning frame 741. The side of the cleaning cylinder 744 contacts the side of the conveyor belt 9. A scraping component 745 is fixedly connected to the middle of the top of the cleaning frame 741. When the conveyor belt 9 rotates normally during the inspection process, the cleaning frame 741 drives the cleaning cylinders 744 on both sides of it to contact the side of the conveyor belt 9 and move with the conveyor belt 9, so as to realize the synchronous linkage of cleaning when the conveyor belt 9 rotates. The cleaning cylinder 744 has evenly spaced slots on its side. These slots can scrape away dust and debris from the side of the conveyor belt 9 like comb teeth, preventing impurities from accumulating on the side of the conveyor belt 9 and ensuring the smooth operation of the conveyor belt 9. Meanwhile, the placement slots on the conveyor belt 9 used to fix the circuit boards will come into contact with the scraping component 745 in the middle of the cleaning frame 741 during rotation. The scraping component 745 can penetrate deep into the inner wall of the placement slot to clean the dust, solder fragments and other impurities remaining in the slot, solving the problem of dirt and grime accumulating in the placement slot and preventing impurities from adhering to the bottom of the board when it is placed in later. The bottom of the cleaning frame 741 is evenly provided with connecting shafts 742. The connecting shafts 742 not only provide stable support for the cleaning frame 741, but the second spring 743 sleeved on its outer side can also continuously apply an upward supporting force to the cleaning frame 741 through the tensile elastic force. When the conveyor belt 9 experiences slight wear, uneven thickness, or small vibrations during operation due to long-term use, the second spring 743 can adaptively adjust the height of the cleaning frame 741 through its own elastic deformation to ensure that the cleaning cylinder 744 always abuts against the side of the conveyor belt 9. The elastic support of the second spring 743 can also buffer the contact pressure between the cleaning cylinder 744, the scraping component 745 and the conveyor belt 9, and avoid rigid collisions that could cause wear on the conveyor belt 9 or the cleaning components. Please see Figure 10 The scraping assembly 745 includes two round rods 7451. The bottom of the round rods 7451 is slidably connected to the top of the cleaning frame 741. A connecting frame 7452 is fixedly connected to the top of the round rods 7451. A third spring 7453 is sleeved on the round rods 7451. The top of the third spring 7453 is fixedly connected to the bottom of the connecting frame 7452. The bottom of the third spring 7453 is fixedly connected to the top of the cleaning frame 741. A rotating shaft 7454 is rotatably connected to the inner side of the connecting frame 7452. Scrapers 7455 are fixedly connected to both sides of the rotating shaft 7454. The side of the scraper 7455 is in contact with the side of the conveyor belt 9. When the cleaning cylinder 744 contacts and cleans the side of the conveyor belt 9, the continuous movement of the conveyor belt 9 will cause the evenly opened placement grooves on it to gradually come into contact with the scraper 7455. The lengths of the scraper 7455 and the connecting shaft 742 are perfectly matched with the opening length of the placement groove, ensuring that the scraper 7455 covers the inner length of the placement groove and avoiding dead corners that cannot be cleaned at both ends due to size mismatch. This allows the scraper 7455 to thoroughly scrape off dust, debris and other impurities attached to the groove when it moves in contact with the placement groove, preventing impurities from accumulating in the groove for a long time and causing unstable support or bottom contamination problems when the circuit board is placed later. During the process of scraper 7455 contacting the inner side of the placement groove, scraper 7455 will be driven by the friction of the groove wall to rotate shaft 7454 flexibly within connecting frame 7452: The rotating design can convert the sliding friction between the scraper 7455 and the inner side of the trough into rolling friction, which can not only reduce the wear on the inner side of the conveyor belt 9 placed in the trough, but also prevent the scraper 7455 from deforming due to hard friction. Meanwhile, the round rods 7451 symmetrically arranged at the bottom of the connecting frame 7452 and the third spring 7453 sleeved on the round rods 7451 will continuously apply elastic force to the connecting frame 7452; When the conveyor belt 9 vibrates, deforms slightly, or has tiny burrs on the edge of the placement trough, the third spring 7453 can adaptively adjust the position and contact pressure of the scraper 7455 through its own elastic deformation, ensuring that the scraper 7455 always abuts against the inside of the placement trough, so that the impurities will not be scraped incompletely due to insufficient pressure, nor will the trough or scraper 7455 be damaged due to excessive pressure. This structure ensures efficient cleaning of the sides of the conveyor belt 9 by the cleaning cylinder 744, while simultaneously completing deep cleaning of the inside of the placement trough. The dual cleaning actions work together to reduce the overall impurity residue rate of the conveyor belt 9 and the trough, providing a reliable guarantee for the accurate placement of the circuit board and interference-free testing. Specific workflow: The circuit boards to be tested are placed sequentially on the conveyor belt 9 of the loading platform 2, and the conveyor belt 9 moves the circuit boards. At the same time, the control panel 6 is operated to start the feeding component 3. The feeding component 3 places the circuit boards one by one into the placement slot of the conveyor belt 9 of the inspection table 1, so as to realize the rapid positioning of the circuit boards and avoid deviation during the conveying process. The conveyor belt 9 of the inspection table 1 drives the circuit board to move continuously. When the circuit board passes the inspection head 8, the inspection head 8 performs a full-area scan on it; on the one hand, it captures images of each solder joint, and on the other hand, it collects the shape, color and polarity data of the components. The pre-processed detection data is encrypted and transmitted to the cloud to ensure real-time transmission; then the cloud AI model identifies the defects, compares the electrical parameters with preset thresholds, and marks the location of the defects. After the inspection is completed, the unloading component 5 picks up the circuit board and moves it to the unloading platform 4 conveyor belt 9, thus completing the circuit board unloading process. During the rotation of the conveyor belt 9 on the testing platform 1, when it passes the contact component 7, the contact component 7 will clean the side of the conveyor belt 9 to prevent dust and impurities from accumulating in the placement slot of the conveyor belt 9, and to prevent dust from adhering when the circuit board is placed, which would lead to testing deviation.
