Description

Technical Field

[0001] This utility model relates to the field of detection technology for series filters, specifically a detection device for locating defects in series multi-system filters. Background Technology

[0002] With the rapid development of communications, power electronics and industrial automation, multi-system series filters (such as LC filters, EMI filters, cascaded filters in digital signal processing, etc.) are widely used for noise suppression, signal purification and spectrum management. However, due to the high system complexity, component parameter drift or physical damage, local defects in series filters (such as capacitor failure, inductor saturation, poor contact, etc.) may lead to overall performance degradation or even system failure. Therefore, series filters need to be tested by testing devices during production and use.

[0003] Existing testing devices lack the function of marking multi-system cascaded filters when testing them. This results in defective multi-system cascaded filters being mixed with qualified ones, increasing the workload during subsequent sorting and making it inconvenient to sort the filters. Furthermore, the sorted multi-system cascaded filters lack the function of regional transport and organization, thus reducing the efficiency of the testing device in testing multi-system cascaded filters.

[0004] According to announcement number CN222337279U, a testing device for producing electromagnetic interference filters includes a workbench. A support frame is fixedly mounted on the top of the workbench. A first groove is formed on the support frame, and a first slider is slidably mounted within the first groove. A robotic arm is mounted at the bottom of the first slider. A drive assembly that drives the first slider to reciprocate is mounted on the support frame. A rotating shaft is symmetrically rotatably mounted on the support frame, and a gear is fixedly sleeved on the top of the rotating shaft. A first rack and a second rack are fixedly mounted on the first slider. A second groove is formed on the workbench, and a second lead screw is rotatably mounted within the second groove. A transmission assembly is provided between the second lead screw and the rotating shaft. Second sliders are threadedly connected to both sides of the second lead screw. Clamping plates are symmetrically mounted on the second lead screw, and springs are fixedly mounted between the clamping plates and the corresponding second sliders. Due to the buffering effect of the springs, the two clamping plates can hold filters of different sizes, enhancing the practicality of the entire device.

[0005] As described above, filters require testing during production and use. Existing testing devices lack the function of marking multi-system cascade filters, leading to defective multi-system cascade filters being mixed with qualified ones. This increases the workload during subsequent sorting, making it inconvenient to sort multi-system cascade filters. Furthermore, sorted multi-system cascade filters lack regional transport and organization functions, thus reducing the efficiency of the testing device in detecting multi-system cascade filters.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] This utility model provides, for example Figures 1-4 The device shown is a detection device for locating defects in series multi-system filters. It includes a conveyor frame 1 with first conveyor belts 2 installed at both ends. Two fixed frames 3 are fixedly connected to the first conveyor belts 2. One fixed frame 3 is equipped with a detection device 4 for detecting series multi-system filters, and the other fixed frame 3 is equipped with a marking machine 5 for marking defective series multi-system filters after detection. A sorting mechanism 6 is set at one end of the two first conveyor belts 2 facing each other. An adjustment mechanism 7 is installed at the lower end of the sorting mechanism 6 and is installed at the center of the conveyor frame 1. The conveyor frame 1 serves as the foundation of the device. The first conveyor belts 2 at both ends carry the detection device 4 and the marking machine 5, respectively. The fixed frames 3 are used to fix the equipment. The two first conveyor belts 2 run in opposite directions, transporting the filters to the sorting mechanism 6 for sorting. The opposing conveyor belts realize the continuity of the detection and marking process and improve efficiency.

[0025] Note: The testing equipment 4 involved in this utility model is a test instrument suitable for testing series multi-system filters, such as a vector network analyzer, a spectrum analyzer with a tracking source, and an impedance analyzer. These are all existing technical products, so their structural models and working principles are not described in detail in this article.

[0026] The center of the conveyor frame 1 is equipped with two second conveyor belts 8 that work with the sorting mechanism 6. The sorting mechanism 6 is located above the second conveyor belts 8. The second conveyor belts 8 can separate qualified and defective products after the series multi-system filter is detected and sorted, thereby transporting the series multi-system filter to different areas.

[0027] The sorting mechanism 6 includes a fixed plate 61, the lower surface of which is connected to the top of the adjusting mechanism 7. The fixed plate 61 is located at one end of the two conveyor belts facing each other. Support frames 62 are fixedly connected to both ends of the fixed plate 61 near the first conveyor belt 2. Robotic arms 63 are installed on the support frames 62. Sorting boxes 64 are snapped into the center of both sides of the fixed plate 61. The sorting boxes 64 are located above the second conveyor belt 8. The fixed plate 61 provides a sorting platform for the series multi-system filters. Then, the robotic arms 63 sort the marked defective series multi-system filters and qualified series multi-system filters into different sorting boxes 64, thereby improving sorting accuracy and efficiency.

[0028] A locking block 65 is fixedly connected to one side of the sorting box 64. An indicator mark 66 is provided on the surface of the locking block 65. A slot 67 is provided on the fixing plate 61 at the position corresponding to the locking block 65. One end of the locking block 65 is locked in the slot 67. The sorting box 64 can be quickly disassembled by fixing the locking block 65 to the slot 67 of the fixing plate 61. Therefore, it is convenient for the sorting box 64 to be conveyed on the second conveyor belt 8, reducing human intervention.

[0029] Positioning blocks 9 are fixedly connected to both ends of the support frame 62. Sliding sleeves 10 are embedded in the positioning blocks 9. Positioning rods 11 are slidably connected to the inner cavity of the sliding sleeves 10. The lower end of the positioning rods 11 is fixed to the conveyor frame 1. Vertical stable movement is achieved through the sliding cooperation between the positioning rods 11 and the sliding sleeves 10, ensuring that the robot arm 63 maintains accurate positioning during the sorting process and avoids shaking.

[0030] The adjusting mechanism 7 includes a connecting rod 71, the lower end of which is movably connected to the conveyor frame 1, and the upper end of which is movably connected to a connecting seat 72. The connecting seat 72 is fixed to the lower surface of the fixed plate 61. An electric push rod 73 is installed at the center of the connecting rod 71. The electric push rod 73 provides driving force, which can drive the upper rod 711 and the lower rod 712 in the connecting rod 71 to rotate around the connecting shaft 713, thereby adjusting the height of the fixed plate 61 so that the sorting box 64 can fall onto the second conveyor belt 8 for conveying, thus meeting the conveying requirements after sorting.

[0031] The connecting rod 71 includes an upper rod 711 and a lower rod 712. The connecting ends of the upper rod 711 and the lower rod 712 are movably connected to a connecting shaft 713. A connecting block 714 is fixedly connected to the center of the connecting shaft 713. An electric push rod 73 is mounted on the connecting block 714. The upper end of the upper rod 711 is movably connected to the connecting seat 72. The lower end of the lower rod 712 is fixedly connected to a rotating shaft 715. The two ends of the rotating shaft 715 are rotatably connected to the conveyor frame 1. The upper rod 711 is connected to the connecting seat 72, and the lower rod 712 is rotatably connected to the conveyor frame 1 through the rotating shaft 715. Therefore, when the electric push rod 73 pushes the connecting block 714, it drives the connecting rod 71 to extend and retract, thereby realizing the lifting and lowering of the sorting mechanism 6.

[0032] In practical use, the first conveyor belts 2 at both ends of the conveyor frame 1 are first equipped with the testing equipment 4 and the inkjet printer 5, respectively. The filter first enters the testing station, where the testing equipment 4 tests its performance. Subsequently, defective products are marked by the inkjet printer 5. The two first conveyor belts 2 run in opposite directions to ensure that the testing and marking processes are continuous, thereby improving production efficiency.

[0033] After testing, the filters are transported to the sorting mechanism 6, which includes a fixed plate 61, a robotic arm 63 and a sorting box 64. The robotic arm 63 grabs the filters according to the test results and puts the qualified and unqualified products into the corresponding sorting box 64 respectively. The sorting box 64 is located above the second conveyor belt 8 to realize automatic diversion, and qualified and unqualified products enter different conveying channels.

[0034] Below the sorting mechanism 6 is an adjustment mechanism 7, which is driven by an electric push rod 73 to extend and retract the connecting rod 71, thereby adjusting the height of the fixed plate 61 so that the sorting box 64 can be accurately connected to the second conveyor belt 8. This allows the sorted series multi-system filters to be transported to different areas via the second conveyor belt 8, thus realizing multi-station parallel operation of the testing device, reducing production time, and improving the working efficiency of the testing device and the portability of transporting series multi-system filters.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
