Description

Technical Field

[0001] This invention belongs to the field of visual inspection technology, specifically an AOI visual inspection device for surface scratches on electronic components. Background Technology

[0002] AOI (Automated Optical Inspection) is an automated inspection technology widely used in manufacturing. It utilizes optical systems (such as high-definition cameras and professional lenses) and advanced image processing algorithms to automatically and non-contactly inspect surface defects, deviations, or other non-conformities during product manufacturing. Its core lies in using a carefully designed lighting system (such as high-angle side lighting, coaxial lighting, and ring lighting) to highlight minute features or defects on the surface of the object being inspected. A high-performance camera then captures the image, which undergoes a series of preprocessing steps (such as noise reduction and enhancement). The captured image is then compared with standards (such as predefined acceptable samples or rules) using template matching, rule comparison, or more advanced machine learning and deep learning algorithms to quickly and accurately determine whether the product is acceptable. AOI inspection not only significantly improves inspection efficiency and accuracy, reduces the subjectivity and fatigue of manual inspection, but also provides real-time feedback on inspection results and can even be linked with production lines to automatically reject non-conforming products and adjust process parameters. It is an important means to improve product quality, reduce production costs, and achieve intelligent manufacturing, and is widely used in electronics, semiconductors, automobiles, displays, and many other fields.

[0003] The existing patents (publication number: CN206684031U) for AOI visual inspection ring light source detection mechanism and (publication number: CN206684026U) for AOI visual inspection diffuse reflection shadowless light source detection mechanism both fail to allow for the flipping of components during use for comprehensive inspection, and also fail to allow for the unloading of components after inspection, thus reducing the performance of the inspection equipment. Therefore, improvements are needed to address these issues. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: an AOI visual inspection device for surface scratches of electronic components, comprising a mounting platform, wherein a first fixing plate and a second fixing plate are fixedly mounted at one end of the top of the mounting platform, a flipping component is mounted between the middle of the first fixing plate and the second fixing plate, a flipping adjustment motor connected to the flipping component is mounted on one side of the second fixing plate, an electronic component body is provided at the end of the flipping component away from the flipping adjustment motor, a rotatable adjustment column is mounted on the top of the mounting platform, a lifting component that can be raised and lowered is mounted on the upper part of the adjustment column, and a clamping and unloading component is mounted at one end of the lifting component.

[0005] Preferably, the flipping component includes a fixed tube fixedly installed on the other side of the second fixed plate, a rotating shaft connected to the output end of the flipping adjustment motor is movably inserted inside the fixed tube, a through circular hole is opened in the middle of the first fixed plate, a bearing is installed inside the through circular hole, a circular plate is fixedly installed on the inner ring of the bearing, and the other end of the rotating shaft passes through the axis of the circular plate and is fixedly connected to the circular plate.

[0007] Preferably, the surface of the fixed tube is provided with a slanted groove, and two insert rods are symmetrically and movably installed through the circular plate. One end of each insert rod is rotatably mounted with a roller, and both rollers are installed inside the slanted groove. The other end of each insert rod is fixedly mounted with a vertical plate, and a pair of support plates are symmetrically fixedly mounted on the lower part of one side of each of the two vertical plates. One pair of support plates provides drag support for the electronic component body.

[0008] Preferably, the installation platform has an inner cavity in the middle, and an unloading and transporting motor is installed inside the inner cavity. An adjusting shaft is fixedly installed at the output end of the unloading and transporting motor. The top of the adjusting shaft moves through the installation platform and is fixedly connected to the bottom of the adjusting column. A vertical groove is opened on the surface of the adjusting column, and a slide rod is fixedly installed inside the vertical groove. A return spring is sleeved on the lower part of the slide rod.

[0009] Preferably, the lifting component includes a slider, which is movably sleeved on the surface of the slide rod and slidably installed inside the vertical groove. The two ends of the return spring are fixedly connected to the bottom of the slider and the bottom of the vertical groove, respectively. An inverted U-shaped frame is fixedly installed at one end of the slider, and an I-shaped block is slidably installed in the middle of the inverted U-shaped frame. An electric telescopic rod is installed in the middle of one end of the slider, and the telescopic end of the electric telescopic rod is fixedly connected to the middle of the I-shaped block.

[0010] Preferably, a vertical mounting plate is fixedly installed on one side of the top of the mounting platform, and a top plate is fixedly installed on one side of the vertical mounting plate. The top of the adjusting column is rotatably connected to the bottom of the top plate, and semi-circular extrusion blocks are symmetrically fixedly installed on the bottom of the top plate through the adjusting column. One of the semi-circular extrusion blocks contacts the top of the slider, causing the slider to compress the reset spring.

[0011] Preferably, the clamping and unloading component includes a connecting rod rotatably connected to both ends of the I-beam block, two pairs of adjusting arms rotatably connected to both sides of the inverted U-shaped frame via a movable shaft, connecting rods rotatably connected to both sides of the upper and lower parts of the I-beam block, a rotating bar fixedly installed on one side of one of the four pairs of adjusting arms closest to the connecting rod, one end of each of the four connecting rods rotatably connected to one end of each of the four rotating bars, and mounting blocks connected between the two pairs of adjusting arms at the same position on both sides of the inverted U-shaped frame via a movable shaft, with clamping blocks fixedly installed on one end of each of the two mounting blocks on opposite sides.

[0012] Preferably, a conveyor belt is installed at the other end of the top of the installation platform.

[0013] Compared with the prior art, the beneficial effects of the present invention are: (1) This AOI visual inspection device has an automatic flipping structure and an automatic clamping and unloading structure. The automatic flipping structure can effectively flip the component, so that scratch detection can be performed on both sides of the component, thereby effectively improving the inspection efficiency. The automatic clamping and unloading structure can unload the component after the inspection is completed, thereby effectively improving the performance of the equipment. (2) After the surface inspection of the upper part of the electronic component body is completed, the rotating shaft and the through circular plate are rotated by starting the flipping adjustment motor. The rotation of the rotating shaft will drive the fixed horizontal plate to flip 180°, and the rotation of the through circular plate will drive the two vertical plates and the two pairs of support plates to flip 180° simultaneously through the two insert rods; the rotation of the two insert rods will drive the two rollers to roll and move inside the inclined groove to exchange positions. The rolling movement of the two rollers will drive the two insert rods to move synchronously. The movement of the two insert rods will drive the two vertical plates and the two pairs of support plates to move, thereby The two pairs of trays are swapped; finally, the fixed horizontal plate drives the electronic component body to rotate 180°, and at the same time, the two pairs of trays also rotate and swap positions. At this time, the pair of trays originally located at the top of the fixed horizontal plate rotates and moves with the fixed horizontal plate to support the electronic component body. The side of the electronic component body that is not detected rotates upward, and the pair of trays originally located at the bottom of the fixed horizontal plate rotates and moves with the fixed horizontal plate to separate from the electronic component body. This allows the side of the electronic component body that is not detected to rotate 180° upward without obstruction, so that the other side can be fully visually inspected for scratches by the CCD camera. (3) The electronic component body is clamped and fixed by two clamping blocks. Then, by starting the unloading and conveying motor, the adjusting shaft drives the adjusting column to rotate 180°. The 180° rotation of the adjusting column will drive the slider, the inverted U-shaped frame, the two clamping blocks and the electronic component body clamped and fixed between the two clamping blocks to rotate. When the slider rotates, it will separate from the semi-circular extrusion block. Then, the elastic restoring force of the reset spring will cause the slider to move upward on the surface of the slide rod and inside the vertical groove. The upward rotation of the slider will drive the inverted U-shaped frame, the two clamping blocks and the electronic component body clamped and fixed between the two clamping blocks to rotate and move upward, so that the electronic component body moves out from the inside of the inverted convex placement slot. Then, the electronic component body is rotated 180° for adjustment. Then, the electronic component body to be tested can be placed inside the inverted convex placement slot again. (4) When the two clamping blocks clamp and fix the tested electronic component body and lift and rotate 180°, the electronic component body will move to the top of the conveyor belt. During the process of the slider rotating to the side of the conveyor belt, the other semi-circular extrusion block will contact the top of the slider, causing the slider to move down and compress the reset spring. The downward movement of the slider will drive the electronic component body to move down to the surface of the conveyor belt through the two clamping blocks. Then, by starting the electric telescopic rod to retract, the electric telescopic rod will drive the I-beam block to slide. The movement of the I-beam block will drive the two mounting blocks to unfold through the four linkage rods, four rotating bars and four pairs of adjusting arms. The unfolding of the two mounting blocks will drive the two clamping blocks to unfold, thereby placing the electronic component body on the surface of the conveyor belt for conveying. When it is necessary to unload again, the above steps can be reversed. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] Example 1, by Figures 1 to 7 The present invention includes an installation platform 1. A first fixing plate 2 and a second fixing plate 3 are fixedly installed at one end of the top of the installation platform 1. A flipping component 4 is installed between the middle of the first fixing plate 2 and the second fixing plate 3. A flipping adjustment motor 5 connected to the flipping component 4 is installed on one side of the second fixing plate 3. An electronic component body 6 is provided at the end of the flipping component 4 away from the flipping adjustment motor 5. A rotatable adjustment column 7 is installed on the top of the installation platform 1. A lifting component 8 that can be raised and lowered is installed on the upper part of the adjustment column 7. A clamping and unloading component 9 is installed at one end of the lifting component 8. The electronic component body 6 can be clamped by the clamping and unloading component 9.

[0018] The flipping component 4 includes a fixed tube 10 fixedly installed on the other side of the second fixed plate 3. A rotating shaft 11 connected to the output end of the flipping adjustment motor 5 is movably inserted inside the fixed tube 10. A through circular hole 12 is opened in the middle of the first fixed plate 2. A bearing 13 is installed inside the through circular hole 12. A circular plate 14 is fixedly installed on the inner ring of the bearing 13. The other end of the rotating shaft 11 passes through the axis of the circular plate 14 and is fixedly connected to the circular plate 14, thereby enabling effective rotation adjustment.

[0019] A fixed horizontal plate 15 is fixedly installed at the end of the rotating shaft 11 away from the flipping adjustment motor 5. An inverted convex placement slot 16 is provided at the end of the fixed horizontal plate 15 away from the rotating shaft 11, and the electronic component body 6 is located inside the inverted convex placement slot 16. A slanted groove 17 is provided on the surface of the fixed tube 10. Two insert rods 18 are symmetrically and movably installed through the circular plate 14. Rollers 19 are rotatably mounted at one end of each insert rod 18, and both rollers 19 are installed inside the slanted groove 17, as shown in the attached diagram. Figure 3 As shown, the two rollers 19 are located at the two farthest points inside the inclined groove 17. The other ends of the two insert rods 18 are each fixedly installed with a vertical plate 20. A pair of support plates 21 are symmetrically fixedly installed on the lower part of one side of each of the two vertical plates 20. The two pairs of support plates 21 are staggered at the top and bottom of the fixed horizontal plate 15. The two pairs of support plates 21 can be effectively staggered by the inclined groove 17 and the rollers 19. The distance between the inner sides of each pair of support plates 21 is less than the width inside the inverted convex placement slot 16. One pair of support plates 21 provides drag support for the electronic component body 6, thereby effectively providing drag support for the electronic component body 6.

[0020] Specifically, as shown in the attached diagram. Figure 3 As shown, two pairs of trays 21 are staggered at the top and bottom of the fixed horizontal plate 15. The pair of trays 21 at the bottom of the fixed horizontal plate 15 can effectively support and drag the electronic component body 6 inside the inverted convex placement slot 16, so that the upper part of the electronic component body 6 is completely exposed without obstruction, so that the surface of the upper part of the electronic component body 6 can be fully visually inspected for scratches by a CCD camera. After the surface of the upper part of the electronic component body 6 is inspected, the rotating shaft 11 and the through circular plate 14 are rotated by starting the flipping adjustment motor 5. The rotation of the rotating shaft 11 will drive the fixed horizontal plate 15 to perform a 180° flipping adjustment, while the rotation of the through circular plate 14 will drive the two vertical plates 20 and the two pairs of support plates 21 to perform a 180° flipping adjustment simultaneously through the two insert rods 18. The rotation of the two insert rods 18 will cause the two rollers 19 to roll and move inside the inclined groove 17 and exchange positions. The rolling movement of the two rollers 19 will cause the two insert rods 18 to move synchronously. The movement of the two insert rods 18 will cause the two vertical plates 20 and the two pairs of support plates 21 to move, thereby causing the two pairs of support plates 21 to exchange positions. Finally, the fixed horizontal plate 15 will cause the electronic component body 6 to rotate 180°. At the same time, the two pairs of support plates 21 will also rotate and exchange positions. At this time, the pair of support plates 21 originally located at the top of the fixed horizontal plate 15 will rotate and move with the fixed horizontal plate 15 to support the electronic component body 6. The side of the electronic component body 6 that is not detected will rotate 180° upwards. The pair of support plates 21 originally located at the bottom of the fixed horizontal plate 15 will rotate and move with the fixed horizontal plate 15 and separate from the electronic component body 6. This will allow the side of the electronic component body 6 that is not detected to rotate 180° upwards without obstruction, so that the other side can be fully visually inspected for scratches by the CCD camera. By rotating the fixed horizontal plate 15 and flipping and exchanging the positions of the two pairs of trays 21, scratch detection can be effectively performed on both sides of the electronic component body 6.

[0021] In Example 2, based on Example 1, an inner cavity 22 is provided in the middle of the mounting platform 1. An unloading and transporting motor 23 is installed inside the inner cavity 22. An adjusting shaft 24 is fixedly installed at the output end of the unloading and transporting motor 23. The top of the adjusting shaft 24 movably passes through the mounting platform 1 and is fixedly connected to the bottom of the adjusting column 7. A vertical groove 25 is provided on the surface of the adjusting column 7. A slide rod 26 is fixedly installed inside the vertical groove 25. A return spring 27 is sleeved on the lower part of the slide rod 26, so that the adjusting column 7 can be effectively rotated and adjusted.

[0022] The lifting component 8 includes a slider 28, which is movably sleeved on the surface of the slide rod 26 and slidably installed inside the vertical groove 25. The two ends of the return spring 27 are fixedly connected to the bottom of the slider 28 and the bottom of the vertical groove 25, respectively. An inverted U-shaped frame 29 is fixedly installed at one end of the slider 28. An I-shaped block 30 is slidably installed in the middle of the inverted U-shaped frame 29. An electric telescopic rod 31 is installed in the middle of one end of the slider 28. The telescopic end of the electric telescopic rod 31 is fixedly connected to the middle of the I-shaped block 30.

[0023] A mounting plate 37 is fixedly installed on one side of the top of the mounting platform 1, and a top plate 38 is fixedly installed on one side of the mounting plate 37. The top of the adjusting column 7 is rotatably connected to the bottom of the top plate 38, and a semi-circular pressing block 40 is symmetrically fixedly installed on the bottom of the top plate 38 through the adjusting column 7. One of the semi-circular pressing blocks 40 contacts the top of the slider 28, causing the slider 28 to compress the return spring 27, thereby effectively adjusting the lifting height.

[0024] The clamping and unloading component 9 includes connecting rods 30 rotatably connected to both ends of the I-beam block 30. Two pairs of adjusting arms 33 are rotatably connected to both sides of the inverted U-shaped frame 29 via movable shafts. Connecting rods 32 are rotatably connected to both sides of the upper and lower parts of the I-beam block 30. A rotating bar 34 is fixedly installed on one side of one of the four pairs of adjusting arms 33 closest to the connecting rod 32. One end of each of the four connecting rods 32 is rotatably connected to one end of each of the four rotating bars 34. Two pairs of adjusting arms 33 on the same side of the inverted U-shaped frame 29 are symmetrically arranged via movable shafts. Mounting blocks 35 are connected between two pairs of adjusting arms 33 at the same position on both sides of the inverted U-shaped frame 29 via movable shafts. Clamping blocks 36 are fixedly installed on one end of each of the two mounting blocks 35 on opposite sides. The electronic component body 6 is clamped between the two clamping blocks 36, thereby enabling effective clamping and disassembly operations of the electronic component body 6.

[0025] Specific details are attached. Figure 5 and Figure 6 As shown, the electronic component body 6 is clamped and fixed by two clamping blocks 36. Then, by starting the unloading and transporting motor 23, the adjusting shaft 24 drives the adjusting column 7 to rotate 180°. The 180° rotation of the adjusting column 7 will drive the slider 28, the inverted U-shaped frame 29, the two clamping blocks 36 and the electronic component body 6 clamped and fixed between the two clamping blocks 36 to rotate. When the slider 28 rotates, it separates from the semi-circular pressing block 40. Then, the elastic restoring force of the return spring 27 causes the slider 28 to move upward on the surface of the slide bar 26 and inside the vertical groove 25. The upward rotation of the slider 28 will drive the inverted U-shaped frame 29, the two clamping blocks 36, and the electronic component body 6 clamped and fixed between the two clamping blocks 36 to rotate and move upward, thereby moving the electronic component body 6 out of the inverted convex placement slot 16. Then, the electronic component body 6 is rotated 180° for adjustment. Then, the electronic component body 6 to be tested can be placed again inside the inverted convex placement slot 16.

[0026] In Example 3, based on Example 2, a conveyor belt 41 is installed at the other end of the top of the mounting platform 1. The conveyor belt 41 can achieve conveying on both sides through a forward and reverse motor. On the other side of the top of the mounting platform 1, at both ends of the conveyor belt 41, there are qualified conveying lines and unqualified conveying lines respectively. The forward and reverse rotation of the conveyor belt 41 can separately convey the detected qualified electronic component bodies 6 and unqualified electronic component bodies 6. A CCD camera is installed on the upper part of one side of the mounting vertical plate 37, located directly above the inverted convex placement slot 16. The CCD camera can effectively detect surface scratches on the electronic component bodies 6. At the same time, a controller connected to the CCD camera is installed on the mounting vertical plate 37. The controller is also connected to the flipping adjustment motor 5, the unloading and handling motor 23, the electric telescopic rod 31, and the conveyor belt 41. The controller can judge the detected structure, and then control the flipping adjustment motor 5, the unloading and handling motor 23, the electric telescopic rod 31, and the conveyor belt 41 to adjust according to the detection results. Specifically, when the two clamping blocks 36 clamp and fix the tested electronic component body 6 and lift and rotate it 180°, the electronic component body 6 will move to the top of the conveyor belt 41. As the slider 28 rotates to one side of the conveyor belt 41, the other semi-circular extrusion block 40 will contact the top of the slider 28, causing the slider 28 to move down and compress the reset spring 27. The downward movement of the slider 28 will drive the electronic component body 6 to move down to the surface of the conveyor belt 41 through the two clamping blocks 36. Then, by activating the retraction of the electric telescopic rod 31, the electric telescopic rod 31 drives the I-beam block 30 to slide. The movement of the I-beam block 30, through the four connecting rods 32, the four rotating bars 34, and the four pairs of adjusting arms 33, will drive the two mounting blocks 35 to unfold. The unfolding of the two mounting blocks 35 will drive the two clamping blocks 36 to unfold, thereby placing the electronic component body 6 on the surface of the conveyor belt 41 for conveying. When unloading is required again, the above steps can be reversed.

[0027] This AOI visual inspection device features an automatic flipping structure and an automatic clamping and unloading structure. The automatic flipping structure effectively flips the components, allowing scratch inspection to be performed on both sides, thus significantly improving inspection efficiency. The automatic clamping and unloading structure unloads the components after inspection, thereby enhancing the device's performance. Furthermore, this AOI visual inspection device has a simple structural design, is easy to use, and its flipping and clamping / unloading operations are stable and reliable. Its performance meets the requirements for AOI visual inspection of surface scratches on electronic components.
