Description

Technical Field

[0001] This utility model relates to the field of visual inspection station technology, specifically an inspection station for visual inspection. Background Technology

[0002] A visual inspection station is an automated inspection device that integrates optical imaging, image acquisition, image processing, and mechanical structure analysis. It is used for high-precision and high-efficiency visual inspection of objects. It captures images of objects using an optical imaging system, converts these images into digital signals using an image acquisition device, and then analyzes and processes the images using an image processing system to output the final inspection results. It is widely used in various fields such as industrial manufacturing, food, pharmaceuticals, and scientific research.

[0003] Because visual inspection has high requirements for the lighting conditions around the inspection station, changes in the surrounding lighting conditions have a significant impact on the accuracy of visual inspection. Furthermore, since ambient light can change due to external factors, the presence of shadows can greatly reduce the image quality, thereby affecting the accuracy of visual inspection. Utility Model Content

[0004] The purpose of this invention is to provide a detection station for visual inspection, in order to solve the problem mentioned in the background art that the ambient light conditions around the detection station have a significant impact on visual inspection, and that the light around the detection station can change due to external factors. When there is strong light or shadow, it will affect the image, thereby affecting the accuracy of visual inspection.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a detection table for visual inspection, comprising a detection table, a plurality of mounting brackets arranged above the detection table, a camera arranged at the bottom of each of the plurality of mounting brackets, a detection component for detecting ambient light arranged outside the mounting brackets, the detection component comprising a plurality of slots arranged on the outer wall of the mounting brackets, a connecting plate arranged inside each of the plurality of slots, and a photosensitive sensor arranged on the outer wall of the connecting plate;

[0006] Each of the aforementioned slots has a cavity on its inner wall. An electromagnet and a magnetic plate are installed inside the cavity. A connecting rod and a spring are installed on one side of the magnetic plate. An activation button is installed on the inner wall of the cavity.

[0007] Preferably, the mounting frame has a hollow structure inside, and the camera is located inside the mounting frame and is rotatably connected to the inner wall of the mounting frame via a connecting shaft. The camera rotates with the mounting frame so that the angle corresponds to the detection table.

[0008] Preferably, the plurality of the holes and slots are distributed in a ring on the outer wall of the mounting frame, the connecting plate is embedded in the inner wall of the holes and slots and is connected to the inner wall of the holes and slots by bolts, and the photosensitive sensor is embedded and connected to the connecting plate near the outer side.

[0009] Preferably, the electromagnet is located inside the cavity and is connected to the inner wall of the cavity by bolts. The electromagnet is electrically connected to the power supply and the photosensitive sensor respectively by wires. One side of the electromagnet is magnetically connected to the magnetic plate inside the cavity.

[0010] Preferably, the magnetic plate is located inside the cavity and is slidably connected to the inner wall of the cavity. One end of the connecting rod is connected to one side of the magnetic plate by a bolt, and the other end extends to the other side of the cavity. The two ends of the spring are respectively connected to the inner wall of the cavity and one side of the magnetic plate.

[0011] Preferably, the activation button is located on the inner wall of the cavity and is electrically connected to the control box via an electrical signal. The magnetic plate slides within the cavity, causing the connecting rod to abut against the activation button.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The circular camera frame allows the visual camera to rotate within the mounting bracket, thereby adjusting the shooting angle. Multiple photosensitive sensors are arranged in a ring on the outer wall of the mounting bracket to detect the intensity of ambient light, enabling the determination of the impact of light on visual capture. This facilitates the adjustment of the camera angle, reduces interference from ambient light, and ensures the effectiveness and accuracy of visual detection.

[0014] 2. When the photosensitive sensor detects an influence on light intensity, it can control the electromagnet to supply power via an electrical signal. The electromagnet is then activated and, in conjunction with the magnetic plate, pushes the linkage to press the activation button. This allows the location of the area with abnormal light to be determined, and helps to avoid it when adjusting the camera angle, ensuring the accuracy of the adjustment.

[0015] This invention uses a sensor to detect the ambient light intensity around the visual inspection camera, and issues an alert when abnormal light is detected. It then adjusts the camera angle to move away from the abnormal light, reducing the impact of light on visual inspection and ensuring the accuracy of visual inspection. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0023] Please see Figures 1-2 A detection station for visual inspection includes a detection station 1. Multiple mounting brackets 2 are mounted on top of the detection station 1 to protect the cameras 201, which are housed within the cameras 201. Cameras 201 are mounted on the bottom of each mounting bracket 2 to capture images for visual inspection. A detection component for detecting ambient light is mounted on the outside of each mounting bracket 2. The detection component includes multiple slots 3 on the outer wall of the mounting bracket 2 for positioning a connecting plate 4 and embedding the connecting plate 4 into the mounting bracket 2. Connecting plates 4 are mounted inside each slot 3. A photosensitive sensor 401 is mounted on the outer wall of the connecting plate 4. The photosensitive sensor 401 converts light signals into electrical signals, thereby indirectly detecting the intensity of light.

[0024] The mounting frame 2 has a hollow structure inside, and the camera 201 is located inside the mounting frame 2 and is rotatably connected to the inner wall of the mounting frame 2 through a connecting shaft. The camera 201 and the mounting frame 2 rotate to make the angle correspond to the detection table 1. Multiple holes and slots 3 are distributed in a ring on the outer wall of the mounting frame 2. The connecting plate 4 is embedded in the inner wall of the holes and slots 3 and is connected to the inner wall of the holes and slots 3 by bolts. The photosensitive sensor 401 is embedded in the connecting plate 4 near the outer side.

[0025] Specifically: During the visual inspection of the workpiece on the inspection table 1, the camera 201 at the bottom of the mounting frame 2 can capture images as the workpiece passes by, and the sensor can perform visual inspection of the workpiece. By installing multiple cameras 201 at different angles on the inspection table 1, the workpiece can be inspected from different angles, improving the accuracy and comprehensiveness of the visual inspection. During the inspection process, the photosensitive sensors 401 on the multiple connecting plates 4 on the outer wall of the mounting frame 2 detect the ambient light around the camera 201, and send a signal to the control box when abnormal light is detected, so as to adjust the angle of the camera 201 in time, avoid light interference, and ensure the effect of visual capture.

[0026] Please see Figures 2-4 Each of the multiple slots 3 has a cavity 5 on its inner wall for storing the electromagnet 501 and the magnetic plate 502. The electromagnet 501 and the magnetic plate 502 are installed inside the cavity 5. When the electromagnet 501 is energized and activated, it generates a magnetic pole that repels the magnetic plate 502, thereby pushing the magnetic plate 502 to slide and extend within the cavity 5. A connecting rod 6 and a spring 7 are provided on one side of the magnetic plate 502. In the normal state, the spring 7 can push and support the magnetic plate 502, thereby moving the connecting rod 6 away from the activation button 8. The activation button 8 is provided on the inner wall of the cavity 5. The activation button 8 can send a signal to remind the location of abnormal light.

[0027] Electromagnet 501 is located inside cavity 5 and is connected to the inner wall of cavity 5 by bolts. Electromagnet 501 is electrically connected to power supply and photosensitive sensor 401 by wires. One side of electromagnet 501 is magnetically connected to magnetic plate 502 inside cavity 5. Magnetic plate 502 is located inside cavity 5 and is slidably connected to the inner wall of cavity 5. One end of connecting rod 6 is connected to one side of magnetic plate 502 by bolts, and the other end extends to the other side of cavity 5. The two ends of spring 7 are connected to the inner wall of cavity 5 and one side of magnetic plate 502, respectively. Activation button 8 is located on the inner wall of cavity 5 and is electrically connected to control box by electrical signal. Magnetic plate 502 slides inside cavity 5, causing connecting rod 6 to abut against activation button 8.

[0028] Specifically: When the photosensitive sensor 401 detects abnormal light, it issues an alert and simultaneously controls the power supply to the electromagnet 501 via an electrical signal. This activates the electromagnet 501, generating magnetic poles that push the magnetic plate 502 to slide and retract within the cavity 5. At the same time, the connecting rod 6 at the other end of the magnetic plate 502 follows suit and moves to contact and press the activation button 8. This triggers the activation button 8 and sends an electrical signal, thereby alerting the user to the location of the abnormal light area outside the mounting bracket 2 and providing auxiliary guidance when the camera 201 adjusts its angle, thus moving it away from the direction of abnormal light, reducing the impact of abnormal light on image capture, and ensuring the effectiveness of visual detection.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
