Description

Technical Field

[0001] This utility model relates to the field of circuit testing technology, and in particular to a circuit defect detection device. Background Technology

[0002] A circuit is a pathway formed by connecting wires and cables, capable of transmitting electrical energy and signals. It exists in power systems, electronic equipment, and communication networks. The quality and layout of circuits directly affect the stability and performance of the system. It is necessary to ensure good conductivity and reliable insulation, and avoid open circuits, short circuits, and aging problems to ensure the normal operation of equipment and electrical safety.

[0003] The circuit defect detection equipment integrates optical imaging and electrical testing technologies. The optical technology can capture surface defects of the circuit in high definition, while the electrical testing can detect hidden problems such as abnormal conduction. This allows the equipment to accurately identify open circuits, short circuits, and insulation damage defects in the circuit, ensuring circuit quality, improving product reliability, and providing key support for circuit quality control in the electronics and power industries.

[0004] In existing circuit defect detection equipment, optical inspection and power-on testing are performed independently and are difficult to synchronize. Optical imaging focuses on surface defect identification, while power-on testing focuses on electrical performance testing. The asynchrony of the two data can lead to missed detections. When power-on testing is abnormal, there is a lack of optical positioning, making it difficult to accurately locate physical defects. This not only reduces efficiency but also causes quality risks due to the separation of processes, and cannot meet the comprehensive inspection needs of high-precision circuits.

Detailed Implementation

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

[0034] Reference Figure 1 and Figure 6 An embodiment of this utility model provides a circuit defect detection device, including a workbench 1, a mounting frame 2 fixedly connected to the top of the workbench 1, a detection mechanism 3 provided on the inner top of the mounting frame 2, the detection mechanism 3 being used to detect the circuit, a conveying mechanism 4 being provided on both the front and rear sides of the top of the workbench 1, the conveying mechanism 4 being used to convey the circuit, and a clamping mechanism 5 being provided on the inner side of the conveying mechanism 4 for clamping the circuit or circuit board.

[0035] The testing mechanism 3 includes an integrated plate 301. The top of the integrated plate 301 is fixedly connected to the inner top of the mounting bracket 2. The bottom of the integrated plate 301 is fixedly connected to a telescopic rod 302. The output end of the telescopic rod 302 is fixedly connected to a spring damper 303. The bottom left and right sides of the integrated plate 301 are respectively fixedly connected to a high-definition camera 304 and an infrared scanner 305. The bottom of the spring damper 303 is fixedly connected to a battery block 306. The bottom of the battery block 306 is fixedly connected to a power-conducting needle 307. The high-definition camera 304, the infrared scanner 305 and the power-conducting needle 307 are integrated through the integrated plate 301. The telescopic rod 302 and the spring damper 303 can adjust and buffer the height of the power-conducting needle 307 contacting the circuit to be tested. The battery block 306 supplies power to the power-conducting needle 307, realizing the linkage between optical detection and power-conducting test. The bottom left and right ends of the integrated plate 301 are both fixedly connected to an illumination component 308.

[0036] Specifically, the testing unit 3 achieves efficient linkage between optical testing and power-on testing. The integrated board 301 serves as a carrier, tightly integrating the high-definition camera 304, the infrared scanner 305, and the power-on probe 307, breaking the limitations of the separation of functions in traditional testing equipment. The high-definition camera 304 is responsible for capturing microscopic defects such as cracks and gaps on the surface of the circuit, while the infrared scanner 305 can penetrate the surface of the circuit to detect internal structural defects or abnormal hot spots, thus completing comprehensive optical testing.

[0037] The adjustment and buffer system composed of telescopic rod 302 and spring damper 303 ensures that the energized needle 307 can contact the circuit to be tested with stable pressure. The telescopic rod 302 can adjust the height of the energized needle 307 according to the thickness and position parameters of the circuit to achieve precise positioning. The spring damper 303 absorbs the impact force through elastic deformation at the moment the energized needle 307 contacts the circuit, avoiding damage to the circuit due to excessive pressure, while ensuring the stability of the energized contact.

[0038] The battery storage block 306 acts as an independent power supply, providing a stable current to the power-on probe 307 to ensure the smooth conduction of the power-on test. During the testing process, optical inspection and power-on testing are carried out simultaneously. When the high-definition camera 304 or infrared scanner 305 detects a potential defect, the system immediately triggers electrical inspection. The power-on probe 307 is used to perform electrical performance testing on the corresponding location to determine whether there is a short circuit or open circuit problem. Conversely, if an abnormality is found during the power-on test, the optical inspection component can quickly perform a secondary scan of the area to achieve accurate location and qualitative analysis of the defect. This not only significantly improves the inspection efficiency but also effectively avoids missed detection problems caused by the separation of inspection links, providing a reliable guarantee for the quality control of the circuit.

[0039] Reference Figure 1 , Figure 3 and Figure 4The conveying mechanism 4 includes two mounting plates 401. The bottom of each mounting plate 401 is fixedly connected to the front and rear ends of the top left side of the workbench 1. A reduction motor 402 is fixedly connected to the top of each mounting plate 401. A threaded screw 403 is fixedly connected to the output end of each of the two reduction motors 402. A sliding block 404 is slidably connected to the outer side of each of the two threaded screws 403. A limit plate 405 is fixedly connected to the right end of each of the two threaded screws 403. A carrier box 406 is fixedly connected between adjacent sliding blocks 404. The conveying mechanism 4 is connected via two reduction motors 401 and 402. Motor 402 drives screw 403 to rotate, causing sliding block 404 to slide left and right along screw 403, thereby enabling automated conveying of carrier box 406. The conveying speed and position of carrier box 406 can be adjusted by controlling the start, stop and speed of geared motor 402. Limit plate 405 can prevent excessive displacement of sliding block 404, enabling independent conveying of different workpieces. Antistatic component 407 is provided on the top of both sliding blocks 404, and shock-absorbing support component 408 is provided between adjacent sliding blocks 404 and carrier box 406.

[0040] Specifically, the conveying mechanism 4 is driven and transmitted by two geared motors 402 to realize the automated and controllable conveying of the workpieces on the line. The two mounting plates 401 serve as a support base and are firmly fixed on the top left side of the workbench 1 to provide support for the entire conveying system. The geared motors 402 can precisely adjust the output speed and direction. The output shaft is directly connected to the threaded screw 403 to convert the rotational motion of the motor into linear motion.

[0041] The transmission pair consisting of the threaded screw 403 and the sliding block 404 has the characteristics of high transmission efficiency and high positioning accuracy. When the geared motor 402 drives the threaded screw 403 to rotate, the sliding block 404 moves linearly along the screw axis, which drives the bearing box 406 to achieve horizontal displacement. The two geared motors 402 operate with the same parameters to ensure that the bearing box 406 moves synchronously.

[0042] The limit plate 405 uses elastic buffer material. When the sliding block 404 reaches the end of its stroke, it can effectively limit the displacement and absorb the impact energy through elastic deformation, thus extending the service life of the equipment and providing an efficient and stable workpiece conveying solution for line defect detection equipment.

[0043] Reference Figure 1 , Figure 2 and Figure 4The antistatic component 407 includes two mounting boxes 4071. The bottom of each mounting box 4071 is fixedly connected to the top of two sliding blocks 404. An antistatic plate 4072 is fixedly connected inside each of the two sliding blocks 404 to prevent static electricity. The shock-absorbing support component 408 includes multiple rubber pads 4081. The adjacent sides of the multiple rubber pads 4081 are fixedly connected between the two sliding blocks 404 and the adjacent bearing box 406. A rubber rod 4082 is fixedly connected between the adjacent rubber pads 4081. A control module 8 is fixedly connected to the front side of the mounting frame 2. Shock-absorbing pillars 9 are fixedly connected to the four corners of the bottom of the workbench 1.

[0044] Specifically, the antistatic component 407 and the shock-absorbing support component 408 work together to significantly improve the stability and safety of the conveying mechanism 4. The two mounting boxes 4071 are fixed to the top of the sliding block 404. The built-in antistatic plate 4072 is made of high-performance conductive material, which can quickly conduct away the static electricity generated by the carrier box 406 during the conveying process, effectively avoiding damage to the electronic components of the circuit by static electricity and ensuring the accuracy and reliability of the circuit detection.

[0045] In the shock absorption support assembly 408, multiple rubber pads 4081 and rubber rods 4082 form an elastic buffer structure. The rubber pads 4081 have good flexibility and resilience, which can absorb the vibration generated by the bearing box 406 during start-up, stop and speed change, and reduce the impact of vibration on the circuit workpiece. The rubber rods 4082 enhance the support rigidity of the overall structure, and maintain the stable posture of the bearing box 406 while buffering the vibration, preventing the circuit from shifting or colliding due to vibration.

[0046] In addition, the control module 8 on the front side of the mounting frame 2 can precisely adjust the operating parameters of the geared motor 402 to achieve intelligent management of the conveying process. The shock-absorbing support 9 at the bottom of the workbench 1 further isolates external vibration sources, providing a stable working environment for the entire detection system, so that the conveying mechanism 4 can improve the smoothness and reliability of operation while ensuring the safety of the line.

[0047] Reference Figure 4 , Figure 5 and Figure 6The mounting bracket 2 has a mounting groove 6 on its rear side. A fan 7 is fixedly connected inside the mounting groove 6 for dust removal. The clamping mechanism 5 includes multiple threaded rods 502. The outer sides of the multiple threaded rods 502 are respectively threaded to the left and right sides of the carrier box 406. A knob 501 is fixedly connected to the left end of the threaded rod 502 at the rear end of the left side. A silicone clamping block 504 is fixedly connected to the right end of the threaded rod 502. Two mounting pads 503 are fixedly connected to the left and right sides of the carrier box 406 for clamping the circuit or circuit board. The lighting component 308 includes two battery blocks 3081. The tops of the two battery blocks 3081 are fixedly connected to the bottom left and right ends of the integrated board 301. Diffuser lamps 3082 are fixedly connected to the bottom of the two battery blocks 3081.

[0048] Specifically, a fan 7 is embedded in the mounting slot 6 on the rear side of the mounting bracket 2. By blowing air in a directional manner, the dust and debris generated during the testing process are blown out of the working area in a timely manner, preventing foreign objects from adhering to the circuit under test or the testing equipment, effectively reducing the false judgment rate caused by impurities, and ensuring the accuracy of the test results.

[0049] The clamping mechanism 5 uses a modular design to achieve stable fixation of circuits and circuit boards of different specifications. Multiple threaded rods 502 pass through the left and right sides of the carrier box 406. By rotating the knob 501, the threaded rods 502 are driven to move axially, which drives the silicone clamping block 504 to achieve tightness adjustment. The silicone clamping block 504 has high surface friction and soft texture, which can firmly clamp the circuit and avoid scratching or damaging the circuit surface. The mounting pad 503 plays a positioning and auxiliary support role, ensuring that the circuit maintains a stable posture during transportation and testing, and preventing the testing accuracy from being affected by shaking.

[0050] The lighting component 308 adopts a dual-light source layout, with two battery blocks 3081 independently powered to ensure that the diffused light 3082 emits light continuously and stably. The diffused light 3082 evenly scatters light to the detection area, eliminating shadow blind spots. Together with the high-definition camera 304 and the infrared scanner 305, it can clearly capture the subtle defects on the circuit surface, improve the clarity and reliability of optical detection, and provide good lighting conditions for the accurate identification of circuit defects.

[0051] Working principle: During operation, the circuit or circuit board is placed in the carrier box 406 of the conveying mechanism 4. The control module 8 regulates the reduction motor 402, which drives the threaded screw 403 to rotate, causing the sliding block 404 to move along the screw, thereby driving the carrier box 406 to convey the workpiece according to the set path and speed. After the knob 501 of the clamping mechanism 5 is rotated, the threaded rod 502 drives the silicone clamping block 504 to clamp the workpiece. The mounting pad 503 assists in positioning and ensures the stability of the workpiece during conveying.

[0052] When the workpiece enters the inspection area, the inspection mechanism 3 starts working. The lighting component 308 at the bottom of the integrated board 301 is powered by the battery block 3081, so that the diffused lamp 3082 provides uniform illumination, creating conditions for optical inspection. The high-definition camera 304 and the infrared scanner 305 start working. The former captures surface defects of the circuit, and the latter penetrates the surface to detect internal defects, thus completing the optical inspection. At the same time, the telescopic rod 302 adjusts the height of the energized needle 307 according to the thickness of the workpiece, the spring damper 303 buffers the contact pressure, and the battery block 306 powers the energized needle 307 to realize the power-on test. The optical and power-on tests are linked. When the optical inspection finds a potential defect, the electrical inspection is immediately triggered to judge the electrical performance. If the power-on test is abnormal, the optical secondary scan is triggered in reverse to accurately locate the problem.

[0053] During the conveying process, the antistatic plate 4072 of the antistatic component 407 continuously conducts static electricity away to protect the circuit components. The rubber pads 4081 and rubber rods 4082 of the shock-absorbing support component 408 absorb vibrations to ensure smooth conveying of the workpiece. The fan 7 on the rear side of the mounting frame 2 runs continuously to blow away dust and debris in the detection area, reducing false detections. The shock-absorbing support column 9 at the bottom of the workbench 1 isolates external vibration interference. Together with the control module 8, it precisely regulates each component to ensure stable operation of the equipment and ultimately achieves efficient and accurate detection of circuit defects.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
