Description

Technical Field

[0001] This utility model relates to the technical field of transparent drawer inspection equipment, specifically a multi-directional inspection device for transparent drawers based on visual inspection. Background Technology

[0002] As a core component of home and industrial storage systems, the quality defects of transparent drawers (such as bubbles, scratches, and deformation) directly affect their sealing performance and service life. However, traditional visual inspection technologies have significant limitations in their adaptability to transparent materials. Drawer-type workpieces have hollow structures and multiple inner walls, making it impossible to cover critical areas such as internal cavities and side wall seams from a single viewing angle. Although existing devices can achieve basic multi-angle coverage through combinations of upward and downward shooting units, they lack the ability to collaboratively image three-dimensional cavities, resulting in a high rate of missed detection for scratches or impurities at the bottom of cavities.

[0003] For example, the light shield integration scheme proposed by the visual inspection machine disclosed in patent CN221782141U for convenient multi-directional inspection achieves surface scanning by deploying multiple sets of CCD cameras on the top and side walls. However, the camera angle adjustment relies on mechanical guide rails, which cannot adapt to drawers of different sizes in real time. At the same time, frequent camera movement and adjustment can easily damage the internal structure due to shaking, reducing its service life. More importantly, the angle between the bottom surface of the hollow drawer and the side wall forms an imaging blind spot. Even with the addition of a top corner camera, a blind spot still exists. To address these issues, we provide a transparent drawer multi-directional inspection device based on visual inspection. Utility Model Content

[0004] The purpose of this invention is to provide a multi-directional inspection device for transparent drawers based on visual inspection, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A vision-based multi-directional inspection device for transparent drawers includes a frame with a platform fixed on it. A support base for placing the transparent drawer is slidably mounted on the platform. A first reflector and a second reflector, rotatable 360°, are sequentially mounted above the platform from right to left. A first camera is mounted at each end of the frame to capture images of the inner sidewall and bottom surface of the transparent drawer reflected by the first reflector. A second camera is mounted on each side of the frame to capture images of the inner sidewall and bottom surface of the transparent drawer reflected by the second reflector. The support base is linked to the first and second reflectors via a linkage structure; as the support base moves, it causes the first and second reflectors to rotate continuously.

[0006] The above-described vision-based multi-directional inspection device for transparent drawers includes a drive mechanism on the frame for moving a support base. The drive mechanism includes a cylinder fixed on the frame, a piston rod at the output end of the cylinder, and a connecting plate fixedly connected to the bottom of the support base at the end of the piston rod.

[0007] The aforementioned vision-based multi-directional inspection device for transparent drawers includes a linkage structure comprising a first rotating rod, a second rotating rod, a third rotating rod, and a fourth rotating rod rotatably mounted on a frame. A first reflector is fixed to the first rotating rod, and a second reflector is fixed to the third rotating rod. A support base and the second rotating rod are connected via a first transmission mechanism. When the support base moves, it drives the second rotating rod to rotate synchronously. The second rotating rod and the first rotating rod are connected via a second transmission mechanism. When the second rotating rod rotates, it drives the first rotating rod to rotate synchronously. The first rotating rod and the fourth rotating rod are connected via a third transmission mechanism. When the first rotating rod rotates, it drives the fourth rotating rod to rotate synchronously. The fourth rotating rod and the third rotating rod are connected via a fourth transmission mechanism. When the fourth rotating rod rotates, it drives the third rotating rod to rotate synchronously.

[0008] The above-described vision-based multi-directional inspection device for transparent drawers: The first transmission mechanism includes a rack fixed on both sides of the support base and a first gear fixed to the end of the second rotating rod, the first gear meshing with the rack.

[0009] The above-described vision-based multi-directional inspection device for transparent drawers: The second transmission mechanism includes a first pulley fixed on a first rotating rod and a second pulley fixed on a second rotating rod, with the first pulley and the second pulley connected by a belt drive.

[0010] The above-described vision-based multi-directional detection device for transparent drawers includes a third transmission mechanism comprising a third gear fixed on a first rotating rod and a second gear fixed on a fourth rotating rod, wherein the second gear meshes with the third gear.

[0011] The above-described vision-based multi-directional inspection device for transparent drawers includes a fourth transmission mechanism comprising a bevel gear fixed on a fourth rotating rod and a bevel gear ring fixed on a third rotating rod, wherein the bevel gear ring meshes with the bevel gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, a support base for placing a transparent drawer is slidably arranged on the machine base. A first reflector and a second reflector that can rotate 360° are arranged sequentially from right to left on the top of the machine base. A first camera is installed at each end of the frame, and a second camera is installed on each side of the frame. The support base cooperates with the first and second reflectors through a linkage structure. When the support base moves, it will drive the first and second reflectors to rotate continuously. Thus, after the transparent drawer is placed on the support base, the movement of the support base will drive the transparent drawer to move continuously on the machine base. During the movement, the first and second reflectors rotate continuously. The first reflector can reflect the images of the inner walls at both ends of the transparent drawer, the inner bottom surface, and the angle area between the inner walls at both ends and the inner bottom surface to the first camera. The second reflector can reflect the images of the inner walls on both sides of the transparent drawer, the inner bottom surface, and the angle area between the inner walls on both sides and the inner bottom surface to the second camera. Therefore, this utility model can acquire multi-directional images of the inner surface of the transparent drawer by using the first camera and the second camera in conjunction with the movement of the transparent drawer, reducing the imaging blind spot and facilitating visual defect detection of the transparent drawer. Furthermore, the first camera and the second camera are installed in fixed positions, eliminating the need for frequent movement and adjustment, which improves the stability during image acquisition. At the same time, it solves the problem that frequent movement and adjustment of the internal structure of the first camera and the second camera can easily cause damage due to shaking and reduce their service life.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figures 1-5 As an embodiment of this utility model, a multi-directional detection device for a transparent drawer based on visual inspection includes a frame 1, a platform 23 fixed on the frame 1, a support 3 slidably mounted on the platform 23 for placing the transparent drawer 2, a first reflector 6 and a second reflector 16 rotatable from right to left on the top of the platform 23, and a first camera 7 for capturing images of the inner sidewall and inner bottom surface of the transparent drawer 2 reflected by the first reflector 6 at both ends of the frame 1, and a second camera 24 for capturing images of the inner sidewall and inner bottom surface of the transparent drawer 2 reflected by the second reflector 16 on both sides of the frame 1, respectively. The support 3 is connected to the first reflector 6 and the second reflector 16 through a linkage structure, and the movement of the support 3 will cause the first reflector 6 and the second reflector 16 to rotate continuously.

[0017] In this embodiment, during use, a support base 3 for placing the transparent drawer 2 is slidably mounted on the machine base 23. Moving the support base 3 causes the transparent drawer 2 to move synchronously on the machine base 23. A first reflector 6 and a second reflector 16, capable of 360° rotation, are sequentially mounted from right to left on the top of the machine base 23. A first camera 7 is mounted at each end of the frame 1, and a second camera 24 is mounted on each side of the frame 1. Both the first camera 7 and the second camera 24 are mounted at an angle. The support base 3 cooperates with the first reflector 6 and the second reflector 16 through a linkage structure. As the support base 3 moves, it causes the first reflector 6 and the second reflector 16 to rotate continuously. Thus, after the transparent drawer 2 is placed on the support base 3, the movement of the support base 3 causes the transparent drawer 2 to rotate synchronously. Drawer 2 moves on machine base 23. During the movement, the first reflector 6 and the second reflector 16 rotate continuously. The first reflector 6 can reflect the images of the inner walls at both ends, the inner bottom surface, and the angle area between the inner walls at both ends and the inner bottom surface of the transparent drawer 2 to the first camera 7. The second reflector 16 can reflect the images of the inner walls on both sides, the inner bottom surface, and the angle area between the inner walls on both sides and the inner bottom surface of the transparent drawer 2 to the second camera 24. Thus, by using the first camera 7 and the second camera 24 in conjunction with the movement of the transparent drawer 2, multi-directional images of the inner surface of the transparent drawer 2 can be acquired. The first camera 7 and the second camera 24 are then connected to the computer signal, and the acquired image information can be directly transmitted to the computer, which is convenient for visual inspection of defects on the surface of the transparent drawer 2.

[0018] As a further embodiment of this utility model, a drive mechanism for moving the support base 3 is provided on the frame 1. The drive mechanism includes a cylinder 4 fixed on the frame 1, a piston rod 5 is provided at the output end of the cylinder 4, and a connecting plate 26 fixedly connected to the bottom of the support base 3 is fixed at the end of the piston rod 5.

[0019] In this embodiment, a limiting groove 27 is provided on the machine base 23, and the connecting plate 26 is movably engaged inside the limiting groove 27 and can slide inside the limiting groove 27. The cylinder 4 is electrically connected to an external power source through a wire. Starting the cylinder 4 can drive the piston rod 5 to extend and retract, thereby causing the connecting plate 26 to move horizontally, which in turn causes the support seat 3 on the connecting plate 26 to move horizontally.

[0020] As a further embodiment of this utility model, the linkage structure includes a first rotating rod 8, a second rotating rod 9, a third rotating rod 17, and a fourth rotating rod 18 rotatably mounted on the frame 1. A first reflector 6 is fixed on the first rotating rod 8, and a second reflector 16 is fixed on the third rotating rod 17. The support base 3 and the second rotating rod 9 are connected by a first transmission mechanism. When the support base 3 moves, it drives the second rotating rod 9 to rotate synchronously. The second rotating rod 9 and the first rotating rod 8 are connected by a second transmission mechanism. When the second rotating rod 9 rotates, it drives the first rotating rod 8 to rotate synchronously. The first rotating rod 8 and the fourth rotating rod 18 are connected by a third transmission mechanism. When the first rotating rod 8 rotates, it drives the fourth rotating rod 18 to rotate synchronously. The fourth rotating rod 18 and the third rotating rod 17 are connected by a fourth transmission mechanism. When the fourth rotating rod 18 rotates, it drives the third rotating rod 17 to rotate synchronously.

[0021] In this embodiment, the third rotating rod 17 is parallel to the moving direction of the support base 3 and perpendicular to the first rotating rod 8. When the support base 3 moves, it is driven by the first transmission mechanism to rotate the second rotating rod 9 synchronously. The second rotating rod 9 is driven by the second transmission mechanism to rotate the first rotating rod 8 synchronously. When the first rotating rod 8 rotates, it drives the first reflector 6 to flip. The first rotating rod 8 is driven by the third transmission mechanism to rotate the fourth rotating rod 18 synchronously. The fourth rotating rod 18 is driven by the fourth transmission mechanism to rotate the third rotating rod 17 synchronously. When the third rotating rod 17 rotates, it drives the second reflector 16 to flip.

[0022] As a further embodiment of this utility model, the first transmission mechanism includes a rack 10 fixed on both sides of the support base 3 and a first gear 11 fixed at the end of the second rotating rod 9, wherein the first gear 11 meshes with the rack 10.

[0023] In this embodiment, when the support base 3 moves, it will drive the rack 10 to move. The first gear 11 meshes with the rack 10 to drive the first gear 11 to rotate. When the first gear 11 rotates, it will drive the second rotating rod 9 to rotate synchronously. In addition, there are two limiting plates 12 fixed on the machine base 23 for limiting the side of the rack 10. The limiting plates 12 are used to limit the side of the rack 10 when it moves to prevent it from shifting position.

[0024] As a further embodiment of this utility model, the second transmission mechanism includes a first pulley 13 fixed on the first rotating rod 8 and a second pulley 14 fixed on the second rotating rod 9, with the first pulley 13 and the second pulley 14 being driven by a belt 15.

[0025] In this embodiment, when the second rotating rod 9 rotates, it will drive the second pulley 14 to rotate. The first pulley 13 is driven to rotate by the belt 15 between the first pulley 13 and the second pulley 14. When the first pulley 13 rotates, it will drive the first rotating rod 8 to rotate.

[0026] As a further embodiment of this utility model, the third transmission mechanism includes a third gear 22 fixed on the first rotating rod 8 and a second gear 21 fixed on the fourth rotating rod 18, wherein the second gear 21 meshes with the third gear 22.

[0027] In this embodiment, when the first rotating rod 8 rotates, it drives the third gear 22 to rotate. The second gear 21 is driven to rotate by meshing with the third gear 22. When the second gear 21 rotates, it drives the fourth rotating rod 18 to rotate synchronously.

[0028] As a further embodiment of this utility model, the fourth transmission mechanism includes a bevel gear 20 fixed on the fourth rotating rod 18 and a bevel gear ring 19 fixed on the third rotating rod 17, wherein the bevel gear ring 19 meshes with the bevel gear 20.

[0029] In this embodiment, the rotation of the fourth rotating rod 18 will drive the bevel gear 20 to rotate. The bevel gear ring 19 meshes with the bevel gear 20 to drive the bevel gear ring 19 to rotate. When the bevel gear ring 19 rotates, it drives the third rotating rod 17 to rotate, thereby driving the second reflector 16 to flip.

[0030] The working principle of this utility model is as follows: During use, a support base 3 for placing the transparent drawer 2 is slidably mounted on the machine base 23. A first reflector 6 and a second reflector 16, capable of 360° rotation, are sequentially arranged from right to left above the machine base 23. A first camera 7 is mounted at each end of the frame 1, and a second camera 24 is mounted on each side of the frame 1. The support base 3, the first reflector 6, and the second reflector 16 are connected by a linkage structure. As the support base 3 moves, it causes the first reflector 6 and the second reflector 16 to rotate continuously, thus allowing the transparent drawer 2 to be placed on the support base 3. Then, the transparent drawer 2 is moved on the machine platform 23 by the drive support 3. During the movement, the first reflector 6 and the second reflector 16 rotate continuously. The first reflector 6 can reflect the images of the inner walls at both ends, the inner bottom surface, and the angle area between the inner walls at both ends and the inner bottom surface of the transparent drawer 2 to the first camera 7. The second reflector 16 can reflect the images of the inner walls on both sides, the inner bottom surface, and the angle area between the inner walls on both sides and the inner bottom surface of the transparent drawer 2 to the second camera 24. Through the movement of the transparent drawer 2 in conjunction with the first camera 7 and the second camera 24, multi-directional image acquisition of the inner surface of the transparent drawer 2 can be performed.

[0031] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
