Description

Technical Field

[0001] This utility model relates to the field of electronic component testing technology, and in particular to an electronic component appearance defect detection device. Background Technology

[0002] Electronic components, also known as electronic parts, are the foundation of electronic products and can be considered the basic elements in electronic circuits. Electronic components all have injection-molded parts and metal conductive parts, and the appearance requirements for these parts are high. For example, the outer surface must be flat and smooth, and there must be no surface pits or edge defects. Therefore, after the electronic components are manufactured, in order to prevent defective products from entering the market, the final processing step is to inspect the appearance of the electronic components and identify defective products.

[0003] In the existing technology, when inspecting the appearance defects of electronic components, the detectors used to inspect the electronic components are mostly installed in a fixed position on the appearance defect inspection device. It is inconvenient to change the position and height of the detectors, which means that only the top or side of the electronic component can be inspected, and other surfaces of the electronic component cannot be inspected. At this time, the staff needs to rotate and adjust the electronic component, which reduces the efficiency of the appearance inspection of electronic components and reduces the practicality of the appearance defect inspection device.

[0031] Reference Figures 1 to 7 This utility model provides an electronic component appearance defect detection device, including a mounting frame 1 and a conveyor belt 2.

A rotating frame 11 is fixedly installed at the bottom end of the drive rod 10. Detectors 12 are fixedly installed on the inner wall of the rotating frame 11. There are three detectors 12, which are respectively fixedly installed on the inner wall of the top and the inner walls on both sides of the rotating frame 11. A fixed column 13 is fixedly installed on the upper surface of the rotating frame 11. A locking block 14 is fixedly installed at the top of the fixed column 13. A slide rail 15 is fixedly installed on the inner wall of the top of the movable frame 4. The fixed column 13 and the locking block 14 are slidably connected to the inner wall of the slide rail 15.

[0032] To adjust the height of detector 12, drive blocks 5 are fixedly installed on the outer walls of both ends of the movable frame 4. A servo motor 6 is fixedly installed on the upper surface of one fixed frame 3. A threaded rotating rod 7 is fixedly installed at the output end of the servo motor 6. The threaded rotating rod 7 passes through the upper surface of the fixed frame 3. The bottom end of the threaded rotating rod 7 is rotatably connected to the inner wall of the bottom end of the fixed frame 3. One drive block 5 is threadedly connected to the outer surface of the threaded rotating rod 7. A limit rod 8 is fixedly installed on the inner wall of the other fixed frame 3. The other drive block 5 is slidably connected to the outer surface of the limit rod 8.

[0033] By setting up a mounting frame 1, a conveyor belt 2, a fixed frame 3, a movable frame 4, a drive block 5, a servo motor 6, a threaded rotating rod 7, a limit rod 8, a drive motor 9, a drive rod 10, a rotating frame 11, a detector 12, a fixed column 13, a locking block 14, and a slide rail 15, the position and height of the detector 12 can be adjusted. This allows multiple surfaces of electronic components to be inspected without the need for manual adjustment, improving the efficiency of electronic component appearance inspection and enhancing the practicality of the appearance defect detection device.

[0034] The upper surface of the mounting frame 1 is provided with a positioning component, which includes a mounting plate 16 and a movable sleeve 17. There are two mounting plates 16 and two movable sleeves 17. The two mounting plates 16 are fixedly installed on the upper surfaces of the same end of the mounting frame 1. The two movable sleeves 17 are rotatably connected to the opposite side walls of the two mounting plates 16. An extension plate 18 is slidably connected to the inner wall of the movable sleeve 17. A limit block 19 is fixedly installed on the side wall of the extension plate 18 away from the mounting plate 16. A limit groove is opened on the side wall of the movable sleeve 17 away from the mounting plate 16. The limit block 19 is slidably connected to the inner wall of the limit groove. A threaded slide rod 20 is slidably connected to the side wall of the two mounting plates 16 away from each other. The threaded slide rod 20 passes through one side of the mounting plate 16 and extends to the other side of the mounting plate 16. A rotating block 21 is rotatably connected to the side wall of the two mounting plates 16 away from each other. The rotating block 21 is threadedly connected to the outer surface of the threaded slide rod 20. The end of the threaded slide rod 20 near the conveyor belt 2 is rotatably connected to the extension plate 18.

[0035] By setting up mounting plate 16, movable sleeve 17, extension plate 18, limiting block 19, threaded slide bar 20 and rotating block 21, the function of adjusting the position of electronic components placed on conveyor belt 2 is realized. By adjusting the position of electronic components, the electronic components can be placed in the middle position of conveyor belt 2 when they are being inspected, thus making the inspection of electronic components more comprehensive and convenient. On the basis of the original, the practicality of the appearance defect inspection device is further improved.

[0036] Working principle: Before inspecting the appearance of electronic components using the appearance defect detection device, the size of the electronic components is observed. When widening the angle between the movable sleeve 17 and the mounting plate 16, the two rotating blocks 21 are rotated. When the rotating blocks 21 rotate, the threaded slide rod 20 extends towards the conveyor belt 2 under the action of the threaded hole. During the extension of the threaded slide rod 20, the movable sleeve 17 is rotated away from the mounting plate 16 by driving the extension plate 18. At the same time, the extension plate 18 slides outward from the inside of the movable sleeve 17. When the two extension plates 18 reach the appropriate position, the rotating blocks 21 are stopped, and the widening of the angle between the movable sleeve 17 and the mounting plate 16 is completed. By reversing the above operation, the angle between the movable sleeve 17 and the mounting plate 16 can be narrowed.

[0037] Before using the appearance defect detection device to inspect the appearance of electronic components, the electronic components are placed on the conveyor belt 2. The conveyor belt 2 slowly moves the electronic components toward the detector 12. The positioning component adjusts the position of the electronic components so that they are in the middle of the conveyor belt 2. When the electronic components reach directly below the detector 12, the drive motor 9 is started. When the drive motor 9 runs, it drives the rotating frame 11 to rotate through the drive rod 10. At the same time, the fixed column 13 and the locking block 14 slide inside the slide rail 15. When the rotating frame 11 rotates, the detector 12, which is installed on the inner wall of the rotating frame 11, rotates outside the electronic components to perform external appearance inspection of the electronic components.

[0038] When adjusting the height of detector 12, servo motor 6 is started. When servo motor 6 runs, it drives threaded rod 7 to rotate. When threaded rod 7 rotates, under the action of threaded hole, driving block 5 slides up or down along the outer surface of limit rod 8, and at the same time drives movable frame 4 to move up or down, thereby adjusting the height of detector 12.

[0039] 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.
