Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, and in particular to a visual inspection device. Background Technology

[0002] Visual inspection uses industrial cameras to replace human eyes in performing functions such as identification, measurement, positioning, and judgment. Visual inspection involves converting the captured target into an image signal using an industrial camera, transmitting it to a dedicated image processing system, and then converting it into a digital signal based on pixel distribution, brightness, color, and other information. The image system performs various calculations on these signals to extract the target's features, and then controls the on-site equipment based on the judgment results. It has immeasurable value in detecting defects and preventing defective products from being delivered to consumers.

[0003] Currently, the vision lens angle of vision inspection devices is in a specific direction and cannot be adjusted. It can only capture images of the workpiece from a specific angle, which prevents it from inspecting multiple surfaces of the workpiece. This results in significant limitations in its inspection capabilities and affects the range of the device's inspection. Therefore, a vision inspection device capable of capturing images from multiple angles is proposed. Utility Model Content

The bearing provides support for the main shaft 3, facilitating its installation and reducing its rotational resistance. A rotating assembly is jointly installed between the main shaft 3 and the frame 1, the rotating assembly including a support base 10, which is fixedly installed on the top of the frame 1, with one side of the outer surface of the support base 10 fixed... A servo motor 2, model JSMA-PUC02D, is installed. A drive gear 9 is fixedly connected to the drive end of the servo motor 2. A driven gear 8 is meshed with one side of the outer surface of the drive gear 9. The driven gear 8 is fixedly installed on the top of the main shaft 3. A slider 11 is fixedly connected to the top of the adjustment rail 5. A circular rail 4 is slidably connected to the top of the slider 11. The circular rail 4 is fixedly connected to the frame 1. The circular rail 4 and the slider 11 cooperate to support and limit the movement of the adjustment rail 5, which can ensure the stability of the movement of the adjustment rail 5.

[0026] An adjustment rail 5 is fixedly connected to one side of the outer surface of the main shaft 3. A slide block 12 is slidably sleeved on the outer surface of the adjustment rail 5. A hand screw 15 is provided at the bottom of the slide block 12. The hand screw 15 passes through the slide block 12 and abuts against the bottom of the adjustment rail 5. The hand screw 15 and the slide block 12 are threadedly connected. The screw section of the hand screw 15 is threadedly connected to the slide block 12, and its top abuts against the adjustment rail 5, thereby achieving the purpose of locking the slide block 12.

[0027] Both sides of the outer surface of the slide block 12 are fixedly connected to the first mounting rod 13. The outer surfaces of the two first mounting rods 13 are rotatably sleeved with the mounting bracket 6. The outer surface of each first mounting rod 13 is threaded with a first locking nut 14, and the first locking nut 14 abuts against the outer wall of the mounting bracket 6. The outer surface of the first mounting rod 13 is provided with an external thread, which cooperates with the first locking nut 14 to facilitate the locking operation. The first locking nut 14 is provided with anti-slip texture on the side of the mounting bracket 6 to increase the friction of the contact surface and ensure the locking effect.

[0028] The mounting bracket 6 has a mounting seat 19 on its inner side. The outer surfaces of the mounting seat 19 are fixedly connected to the second mounting rods 18 on both sides. The second mounting rods 18 pass through the mounting bracket 6 and are rotatably connected to it. The outer surface of each second mounting rod 18 is threaded with a second locking nut 17, and the second locking nut 17 abuts against the outer wall of the mounting bracket 6. The outer surface of the second mounting rod 18 is provided with an external thread, which cooperates with the second locking nut 17 to facilitate the locking operation. The second locking nut 17 is provided with anti-slip texture on the side of the mounting bracket 6 to increase the friction of the contact surface and ensure the locking effect.

[0029] Mounting bracket 19 is equipped with a vision inspection component, which includes a fill light 16 and a CCD industrial camera 7. The fill light 16 is model HL-RL12090K, and the CCD industrial camera 7 is model OPT-MC200-FD. Both the fill light 16 and the CCD industrial camera 7 are fixedly connected to the mounting bracket 19. The fill light 16 and the CCD industrial camera 7 are coaxially set. The coaxial setting can ensure that the light from the fill light 16 is evenly illuminated on the subject, avoiding uneven lighting or excessive shadows, thereby improving the overall texture and clarity of the captured image.

[0030] Working principle: Before use, the entire assembly can be installed on one side of the top of the housing of the belt conveyor 20 (e.g., Figure 4 As shown), an existing PLC controller is added. The PLC controller is electrically connected to the servo motor 2, belt conveyor 20, CCD industrial camera 7, and fill light 16 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that this hardware structure improvement can achieve in combination with common knowledge.

[0031] First, adjust the shooting position of the CCD industrial camera 7 by loosening the hand screw 15. Then, hold the CCD industrial camera 7 and loosen the first locking nut 14 and the second locking nut 17 in sequence. Next, move the CCD industrial camera 7 to the corresponding position. During this process, the angle between the mounting base 19 and the mounting bracket 6 changes, and the angle between the mounting bracket 6 and the slide 12 also changes. The slide 12 moves along the adjustment track 5. After the adjustment is completed, tighten the first locking nut 14, the second locking nut 17, and the hand screw 15 in sequence. Fine adjustments can then be made as needed. When inspecting the workpiece, the PLC controller controls the belt conveyor 20 to run intermittently. When the workpiece moves to the corresponding position, the servo motor 2 controls the drive gear 9 to rotate intermittently. The drive gear 9 drives the main shaft 3 to rotate through the driven gear 8. The main shaft 3 drives the CCD industrial camera 7 and the supplementary light 16 to move intermittently through the adjustment track 5, the slide 12, the mounting bracket 6, and the mounting base 19, so as to shoot and inspect multiple sides of the workpiece.
