Description
Technical Field
[0001] The utility model relates to the field of visual detection devices, in particular to a visual detection device capable of reducing the error rate of visual detection. Background Art
[0002] Visual inspection is a technology that uses a visual system for automatic or semi-automatic inspection, usually used to detect and evaluate the quality and integrity of products or components during the manufacturing process. This technology can be applied in various industrial fields, such as electronic manufacturing, automotive industry, food processing, etc., to ensure that products meet standards and specifications, usually using dedicated visual inspection devices for this work.
[0003] In traditional visual inspection devices, the main bracket provides a stable support structure and is usually made of solid metal materials such as aluminum alloy or steel to ensure the safe fixation of the camera and light source. The sensor and feedback system detects the camera position and light source brightness, and feeds this information back to the control unit to automatically adjust the parameters of the device and select high-resolution, high-sensitivity industrial-grade cameras that can capture clear, detail-rich images.
[0004] However, the lighting structure in traditional visual inspection devices is often fixed inside or on the top of the device. This single fixing method is not adjustable, which may cause visual inspection errors due to insufficient lighting during the inspection of different products, thereby reducing the inspection accuracy. Utility Model Content
[0005] In order to make up for the above deficiencies, the utility model provides a visual inspection device that reduces the visual inspection error rate, aiming to improve the problem that the lighting structure in the traditional visual inspection device is not adjustable, which may lead to visual inspection errors due to insufficient lighting during the inspection process of different products, thereby reducing the inspection accuracy.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a visual inspection device for reducing the error rate of visual inspection, comprising a body, a plurality of fixed plates fixedly connected to the top of the body, a support platform fixedly connected to the top of the fixed plate, a motor 1 fixedly connected to the side wall of the support platform, a rotating frame fixedly connected to the output end of the motor 1, the rotating frame rotatably connected to the side wall of the support platform, a fixed ring rotatably connected inside the rotating frame, a lamp tube fixedly connected inside the fixed ring, a motor 2 fixedly connected to the side wall of the support platform, a connecting frame fixedly connected to the output end of the motor 2, the connecting frame rotatably connected to the side wall of the fixing ring, a connecting rod fixedly connected to the top of the connecting frame, a diffusion plate fixedly connected to the top of the connecting rod, an imaging component is arranged inside the body, and the imaging component is used to capture images.
[0007] Furthermore, the imaging component includes a camera, and the camera is fixedly connected inside the body.
[0008] Furthermore, the camera side wall is fixedly connected with a fixing plate, and a plurality of inclined grooves are provided inside the fixing plate.
[0009] Furthermore, the inclined grooves are arranged in a ring array relative to the fixed disk.
[0010] Furthermore, the side wall of the machine body is rotatably connected to an inner connecting ring, and the outer wall of the inner connecting ring is fixedly connected to a plurality of connecting blocks.
[0011] Furthermore, the connection blocks are arranged in a ring array, and sliding grooves are provided inside the connection blocks.
[0012] Furthermore, an outer connecting ring is fixedly connected to the outer wall of the connecting block, and a sliding shaft is arranged inside the connecting block.
[0013] Furthermore, the sliding shaft is slidably connected inside the sliding groove, one end of the sliding shaft is fixedly connected to an inclined plate, and the inclined plate is rotatably connected to a side wall of the fixed disk.
[0014] The utility model has the following beneficial effects:
[0015] 1. In the utility model, firstly, the rotating frame is driven by motor 1 to rotate on the side wall of the support platform, and motor 2 drives the connecting rod to rotate on the side wall of the support platform, so that the vertical and horizontal angles of the fixed ring can be tilted. Thus, the lighting range of the lamp tube can be adjusted according to work requirements, and the lighting range is expanded by the diffusion plate, ensuring that the target object has sufficient contrast and brightness under the camera, so as to facilitate subsequent image processing and analysis, and reduce the error rate of visual detection.
[0016] 2. In the utility model, multiple connecting blocks on the outer wall of the inner connecting ring move centripetally. Since the sliding shaft is inside the sliding groove, the sliding groove pushes the sliding shaft to slide inside it, and finally drives the sliding shaft to rotate. At this time, the inclined plate at one end of the sliding shaft can rotate on the side wall of the fixed disk to expose the camera. This structure can protect the camera from dust and water, thereby increasing the service life of the camera. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1-Figure 2 The utility model provides an embodiment: a visual inspection device for reducing the error rate of visual inspection, including a body 1, a plurality of fixed plates 2 are fixedly connected to the top of the body 1, a support 3 is fixedly connected to the top of the fixed plate 2, a motor 4 is fixedly connected to the side wall of the support 3, a rotating frame 5 is fixedly connected to the output end of the motor 4, the rotating frame 5 is rotatably connected to the side wall of the support 3, a fixed ring 7 is rotatably connected inside the rotating frame 5, a lamp tube 6 is fixedly connected inside the fixed ring 7, a motor 2 8 is fixedly connected to the side wall of the support 3, a connecting frame 9 is fixedly connected to the output end of the motor 2 8, the connecting frame 9 is rotatably connected to the side wall of the fixing ring 7, a connecting rod 10 is fixedly connected to the top of the connecting rod 10, a diffusion plate 11 is fixedly connected to the top of the connecting rod 10, and an imaging component is arranged inside the body 1, and the imaging component is used to capture images.
[0024] Specifically, start motor 1 4, which drives the rotating frame 5 to rotate on the side wall of the support platform 3. By tilting the rotating frame 5 at an angle, the internal fixed ring 7 rotates accordingly, thereby changing the horizontal illumination angle of the lamp tube 6. At the same time, start motor 2 8 to rotate the connecting rod 10 on the side wall of the support platform 3, driving the fixed ring 7 to tilt in a vertical direction. Such a structural design allows the lighting range of the lamp tube 6 to be adjusted according to actual work needs. The use of the diffuser plate 11 further expands the lighting range, ensuring that the camera 12 can capture a clear image of the target object, ensuring the accuracy of the image processing and analysis stages. Such an adjustment mechanism effectively reduces the error rate that may occur during the visual inspection process, so that the device can always maintain stable and reliable detection performance under different working conditions.
[0025] Reference Figure 3 The imaging component includes a camera 12, which is fixedly connected to the inside of the body 1. A fixed plate 13 is fixedly connected to the side wall of the camera 12. A plurality of inclined grooves 14 are provided inside the fixed plate 13. The inclined grooves 14 are arranged in a ring array relative to the fixed plate 13. An inner connecting ring 18 is rotatably connected to the side wall of the body 1. A plurality of connecting blocks 16 are fixedly connected to the outer wall of the inner connecting ring 18. The connecting blocks 16 are arranged in a ring array. Slide grooves 17 are provided inside the connecting blocks 16. An outer connecting ring 15 is fixedly connected to the outer wall of the connecting block 16. A sliding shaft 19 is arranged inside the connecting block 16. The sliding shaft 19 is slidably connected inside the sliding groove 17. An inclined plate 20 is fixedly connected to one end of the sliding shaft 19. The inclined plate 20 is rotatably connected to the side wall of the fixed plate 13.
[0026] Specifically, rotating the inner connecting ring 18 drives the outer connecting ring 15 to rotate synchronously on the side wall of the fixed disk 13. During this process, the multiple connecting blocks 16 on the outer wall of the inner connecting ring 18 move inward. These connecting blocks 16 interact with the slide groove 17 on the sliding shaft 19, pushing the sliding shaft 19 to slide in the slide groove 17. As the sliding shaft 19 slides, its cross-sliding with the multiple outer connecting rings 15 causes the sliding shaft 19 to start rotating. This rotational action enables the inclined plate 20 at one end of the sliding shaft 19 to rotate on the side wall of the fixed disk 13, thereby fully revealing the camera 12. This design not only realizes the rapid exposure and hiding of the camera 12, but also effectively prevents dust and moisture from entering, significantly increasing the service life of the camera 12.
[0027] Working principle: When it is necessary to adjust the lighting angle of the lamp 6 to the product, the starting motor 1 4 can drive the rotating frame 5 to rotate on the side wall of the support platform 3. At this time, the angle of the rotating frame 5 is tilted to drive the fixed ring 7 inside to rotate and thus change the horizontal angle. The starting motor 2 8 can drive the connecting rod 10 to rotate on the side wall of the support platform 3 and drive the fixed ring 7 on the side wall to tilt vertically. With this structure, the lighting range of the lamp 6 can be adjusted according to work requirements, and the lighting range is expanded by the diffusion plate 11, ensuring that the target object has sufficient contrast and brightness under the camera 12, so as to facilitate subsequent image processing and analysis, reduce the error rate of visual detection, and use the camera 12 when it is necessary. When the inner connecting ring 18 is rotated, the inner connecting ring 18 is subjected to force and drives the outer connecting ring 15 on its outer wall to rotate synchronously on the side wall of the fixed disk 13. At this time, the multiple connecting blocks 16 on the outer wall of the inner connecting ring 18 move centripetally. Since the sliding shaft 19 is inside the sliding groove 17, the sliding groove 17 pushes the sliding shaft 19 to slide inside it. During the sliding process of the sliding shaft 19, it will synchronously cross-slide on multiple outer connecting rings 15, thereby driving the sliding shaft 19 to rotate. At this time, the inclined plate 20 at one end of the sliding shaft 19 can rotate on the side wall of the fixed disk 13 to expose the camera 12. This structure can protect the camera 12 from dust and water, thereby increasing the service life of the camera 12.
