Description

Technical Field

[0001] This utility model relates to the field of surface mount inductor testing equipment, specifically a surface mount inductor testing device. Background Technology

[0002] Before shipment, surface mount inductors need to be inspected for appearance. The screening of good and bad products is mainly done manually. When inspectors are tired from visual inspection, errors are likely to occur in the screening of products. Good and bad products are often mixed up due to human factors. Therefore, high-definition cameras can be used to inspect surface mount inductors.

[0003] According to a patent document with publication number CN216622507U, a surface mount inductor testing device includes a mounting plate. Several support columns are fixedly connected to the lower surface of the mounting plate. A drive motor is fixedly mounted on the lower surface of the mounting plate. A connecting shaft is fixedly connected to the output end of the drive motor. A drive gear is fixedly connected to one end of the connecting shaft. The drive gear meshes with a driven gear. The radius of the drive gear is smaller than that of the driven gear. A rotating shaft is fixedly connected inside the driven gear. In use, by setting up the drive motor, its rotation drives the connecting shaft, drive gear, driven gear, rotating shaft, and testing stage to rotate. The smaller radius of the drive gear allows the driven gear to rotate at a lower speed than the drive gear, ultimately slowing down the testing stage's rotation speed. This facilitates adjustment and control of the testing stage's speed, preventing excessive speed and increased false positive rates. However, while this solution achieves speed control, it cannot simultaneously adjust the position and height of the surface mount inductor while adjusting the camera position, causing inconvenience in use. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a surface mount inductor testing device to solve the problems mentioned in the background section. This invention features a novel structure. In use, the lifting mechanism moves the light-shielding box downwards to the side of the fixed frame. The light-shielding box provides light shielding during testing, and supplementary lighting is provided by the camera's built-in supplementary light. By moving the light-shielding box downwards, the surface mount inductor can be pushed upwards to adjust to the required height.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surface mount inductor detection device, comprising a fixed base, a movable base movably mounted inside the fixed base, a movable plate movably mounted inside the movable base, a support plate fixed to the top of the fixed base, a limit plate movably mounted on the side of the support plate, a slider fixed to the bottom of the limit plate, a groove formed on the movable base, the slider movably mounted inside the groove, a lifting mechanism fixed inside the support plate, and a mounting base fixed to one end of the lifting mechanism.

[0006] Furthermore, a light-shielding box is movably mounted on the bottom of the mounting base, and a threaded tube and a positioning post are fixed on the top of the light-shielding box, while mounting holes and positioning holes are respectively opened on the bottom of the mounting base.

[0007] Furthermore, the threaded tube is movably installed inside the mounting hole, the positioning pin is movably installed inside the positioning hole, a fixing bolt is rotatably installed between the threaded tube and the mounting base, and a baffle and a camera are respectively fixed inside the light shield.

[0008] Furthermore, the movable seat has a limit groove on its side, and a limit block is movably installed inside the limit groove. One end of the limit block is fixed to the movable plate, and the limit block is installed inside the limit groove through a support mechanism. A protrusion is fixed on the movable plate.

[0009] Furthermore, a connecting groove is formed inside the support plate, and a connecting block is movably installed inside the connecting groove. One end of the connecting block is fixed to the limiting plate, and a tension mechanism is fixed between the connecting block and the connecting groove.

[0010] Furthermore, a fixing frame is movably mounted on the movable plate, the bottom of the fixing frame has a connecting hole, the movable plate has a fixing hole, a limit bolt is rotatably installed between the fixing hole and the connecting hole, and the movable plate has an opening.

[0011] Furthermore, a support plate is movably mounted inside the opening, a surface mount inductor is movably mounted on the support plate, and a movable column is fixed at the bottom of the support plate.

[0012] Furthermore, a limiting plate is fixed to one end of the movable column, a reset mechanism is fixed on the limiting plate, one end of the reset mechanism is fixed to the bottom of the support plate, and a friction pad is fixed on the inner wall of the opening, the friction pad being in contact with the movable column.

[0013] The beneficial effects of this utility model are: In use, the lifting mechanism moves the light-shielding box downwards to the side of the fixed frame. The light-shielding box provides light protection during testing, and the camera's built-in supplementary lighting provides illumination. The downward movement of the light-shielding box can push the surface-mount inductor upwards to adjust to the required height.

[0014] In this invention, after the light-shielding box is moved to the side of the fixed frame, the light-shielding box limits and fixes the movable plate through the fixed frame. Later, when the movable plate moves to one side and is pressed, the pressing causes the movable column to push the support plate upward and push the chip inductor out of the fixed frame, which facilitates quick material handling later.

[0015] In this utility model, after the limiting plate moves upward, the slider separates from the slide groove, and the movable plate can be quickly disassembled. After the movable plate is disassembled, the size of the fixing frame can be replaced. Different sizes of fixing frames limit and fix different sizes of surface mount inductors. Similarly, the size and shape of the light shielding box also change accordingly. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1 to 6 This utility model provides a technical solution: a patch inductor detection device, including a fixed base 1, a movable base 4 movably installed inside the fixed base 1, a movable plate 5 movably installed inside the movable base 4, a support plate 2 fixed to the top of the fixed base 1, a limit plate 3 movably installed on the side of the support plate 2, a slider 10 fixed to the bottom of the limit plate 3, a groove 9 opened on the movable base 4, and the slider 10 movably installed inside the groove 9. A lifting mechanism 6 is fixed inside the support plate 2, a mounting base 7 is fixed to one end of the lifting mechanism 6, a light shield 8 is movably installed at the bottom of the mounting base 7, a threaded tube 27 and a positioning post 28 are fixed to the top of the light shield 8, and mounting holes and positioning holes are opened at the bottom of the mounting base 7. The lifting mechanism 6 is a linear reciprocating electric push rod. The lifting mechanism 6 drives the mounting base 7 to move upward while controlling the up and down movement of the movable plate 5. The movement of the mounting base 7 and the movable plate 5 controls the distance between the patch inductor and the camera 25, which facilitates clearer data acquisition and detection later.

[0019] In this embodiment, the threaded tube 27 is movably installed inside the mounting hole, the positioning pin 28 is movably installed inside the positioning hole, and a fixing bolt 24 is rotatably installed between the threaded tube 27 and the mounting base 7. A baffle 26 and a camera 25 are fixed inside the light shield 8, respectively. A limit groove is opened on the side of the movable base 4, and a limit block 11 is movably installed inside the limit groove. One end of the limit block 11 is fixed to the movable plate 5. The limit block 11 is installed inside the limit groove through a support mechanism 12. A protrusion 14 is fixed on the movable plate 5. A connecting groove 21 is opened inside the support plate 2, and a connecting block 23 is movably installed inside the connecting groove 21. One end of the connecting block 23 is fixed to the limit plate 3. A tension mechanism 22 is fixed between the connecting block 23 and the connecting groove 21. Both the support mechanism 12 and the tension mechanism 22 are springs. The support mechanism 12 uses its own elasticity to make the movable plate 5 quickly return to its position.

[0020] In this embodiment, a fixing frame 13 is movably mounted on the movable plate 5. A connecting hole is opened at the bottom of the fixing frame 13. A fixing hole 15 is opened on the movable plate 5. A limit bolt is rotatably installed between the fixing hole 15 and the connecting hole. An opening 16 is opened on the movable plate 5. A support plate 17 is movably mounted inside the opening 16. A surface mount inductor is movably mounted on the support plate 17. A movable column 18 is fixed at the bottom of the support plate 17. A limit plate 20 is fixed at one end of the movable column 18. A reset mechanism 19 is fixed on the limit plate 20. One end of the reset mechanism 19 is fixed to the bottom of the support plate 17. A friction pad is fixed on the inner wall of the opening 16. The friction pad is in contact with the movable column 18. The reset mechanism 19 is a reset spring. After the movable plate 5 is released from pressure, the reset mechanism 19 pushes the limit plate 20 downward, causing the support plate 17 to move into the opening 16 for storage and return to its original position.

[0021] Working principle: In use, the movable seat 4 moves on the fixed seat 1 via the protrusion 14. One end of the slide groove 9 moves to the slider 10 for limiting. After the movable seat 4 moves, the fixed frame 13 is pulled outward, and the surface mount inductor is installed inside the fixed frame 13. The inner wall of the fixed frame 13 supports and limits the side of the surface mount inductor. The surface mount inductor is placed on the top of the support plate 17. Then, the movable seat 4 is pushed back to its original position. After the movable seat 4 returns to its original position, the fixed frame 13 moves to the bottom of the light shield 8. The lifting mechanism 6 is activated, which moves the mounting base 7. The lifting mechanism 6 is connected to an external switch via a wire. The external switch controls the extension and retraction of the lifting mechanism 6. The lifting mechanism 6 moves the light shield 8 to the bottom of the fixed frame 17. After the fixed frame 13 is in place, the baffle 26 moves to the top of the fixed frame 13. When the light shield 8 presses the movable plate 5 again, the movable plate 5 moves downward, and the bottom of the limiting plate 20 contacts the movable seat 4. With the movable plate 5 descending and the support plate 17 not moving, the patch inductor on the support plate 17 moves towards the camera 25, thereby completing the limiting and fixing of the movable plate 5 while adjusting the distance between the patch inductor and the camera 25, thus achieving better detection. After the detection is completed, the movable seat 4 drives the movable plate 5 to move outward. Pressing the movable plate 5 again, the support plate 17 pushes the patch inductor upward. After the patch inductor moves to the top of the fixed frame 13, it is convenient to quickly remove the patch inductor later.
