Description

Technical Field

[0001] This utility model relates to the field of product appearance inspection technology, and in particular to a rapid visual inspection device for appearance defects of water supply valves. Background Technology

[0002] In industrial production, product quality inspection is crucial. This is especially true for various valve products, whose appearance quality not only affects their overall aesthetics but also has a significant impact on their performance and reliability. With the continuous development of the manufacturing industry, the requirements for the accuracy and efficiency of product appearance defect detection are also increasing. Traditional manual inspection methods are gradually becoming insufficient to meet the demands of large-scale, high-precision production. Therefore, automated appearance inspection technology has emerged and is playing an increasingly important role in industrial production.

[0003] In the past, the inspection of appearance defects in water supply valves mainly relied on manual visual inspection and simple mechanical measurement methods. Manual visual inspection depends on inspectors visually observing the appearance of the valves to determine the presence of defects such as scratches, cracks, and deformation. While this method offers some flexibility, it is limited by human subjective judgment and fatigue, resulting in poor accuracy and consistency of the inspection results. Furthermore, the inspection speed is slow and cannot adapt to the pace of large-scale production. Therefore, a device and method are needed that can quickly and accurately detect appearance defects in water supply valves. Utility Model Content

It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0030] This utility model discloses a rapid visual inspection device for appearance defects in water supply valves, such as... Figure 1 and Figure 2As shown, the system includes a frame 1, on which multiple sample containers 2 are mounted. Two slide rails 6 are also mounted on the frame 1. One slide rail 6 is used for testing the sample containers 2, while the other is used for reassembling samples into the sample containers 2. This configuration allows for parallel operations of testing and reassembly, improving overall work efficiency. The slide rails 6 are typically made of metal with a smooth surface to reduce friction. The frame 7 at the bottom of the sample container 2 slides on the slide rail 6; the fit between the frame 7 and the slide rail 6 must be tight and smooth to ensure stable movement of the sample container 2.

[0031] A pusher 3 is provided on one side of the sample container 2. The pusher 3 drives the sample container 2 to move along the circular conveyor line. The pusher 3 includes a fixed frame 31 mounted on the frame 1. The fixed frame 31 is generally made of metal and is fixed to one end of the slide rail 6 by welding. A pusher cylinder 32 is mounted on the fixed frame 31, which is the power source for moving the sample container 2. The output shaft of the pusher cylinder 32 passes through the fixed frame 31, and its end is connected to a pusher plate 33. The pusher plate 33 is a flat metal plate, which is firmly connected to the output shaft of the pusher cylinder 32 by bolts. When the pusher cylinder 32 is working, the output shaft extends and drives the pusher plate 33 to move, which in turn pushes the frame 7, causing the sample container 2 to move along the circular conveyor line.

[0032] A limit rod 17 is also provided on the side of the movable block 8 away from the slide rail 6. The limit rod 17 is a metal rod that limits the pushing position of the frame 7. A rubber pad 18 is fixed to the end of the limit rod 17. The rubber pad 18 can buffer the collision between the frame 7 and the limit rod 17 and reduce damage. The limit rod 17 is fixed to the frame 1 by a third support frame 19, which is also made of metal.

[0033] A movable block 8 is provided at the end of the slide rail 6. The movable block 8 has a slot 9 for engaging the frame 7 pushed from the slide rail 6. A movable component 10 is provided at the bottom of the movable block 8. The movable component 10 includes a first slider 101 located at the bottom of the movable block 8. The first slider 101 is a block-shaped structure and is fixedly connected to the movable block 8 by bolts or other means. A lead screw 102 is connected to the first slider 101. The lead screw 102 is a transmission component that, by rotation, drives the first slider 101 to move axially along the lead screw 102. A servo motor 103 is connected to the end of the lead screw 102. The servo motor 103 is fixed to the frame 1 and provides power for the rotation of the lead screw 102. A guide rod 104 is also provided on one side of the lead screw 102. The guide rod 104 passes through the slider and serves as a guide, ensuring the straightness of the movement of the first slider 101.

[0034] A first camera 4 and a second camera 5 are mounted at both ends of the frame 1, and are fixed above the sample container 2 by a first support frame 11. The first support frame 11 is generally made of metal profiles, providing good stability. The first camera 4 and the second camera 5 are responsible for capturing front and side images of the water supply valve terminal, respectively. The first camera 4 can be a high-resolution industrial camera, capable of clearly capturing the detailed features of the front of the water supply valve. The second camera 5 is also a high-resolution camera to accurately acquire side images. A fill light plate 12 is also mounted on the first support frame 11. The fill light plate 12 is generally a smooth-surfaced plate, which can be made of plastic or metal. The fill light plate 12 is equipped with lights to provide sufficient light during shooting, ensuring image clarity.

[0035] A suction block 13, made of an electromagnet, is provided on one side of the second camera 5. When the electromagnet is energized, it generates magnetism and can attract specific objects. A second slider 14, typically a metal block in the shape of a square, is provided on one side of the suction block 13. A second support frame 15, also made of metal profile, is provided on one side of the second slider 14. The second slider 14 is slidably connected to the second support frame 15, allowing the suction block 13 to slide up and down on the second support frame 15. A lifting cylinder 16 is provided on the top of the suction block 13. The output shaft of the lifting cylinder 16 is connected to the top of the suction block 13, and the lifting cylinder 16 is fixed to the second support frame 15. When the lifting cylinder 16 operates, the output shaft extends and retracts, causing the suction block 13 to move up and down, thus adjusting the position of the suction block 13.

[0036] Working Principle: This utility model discloses a rapid visual inspection device for water supply valve appearance defects. A frame 1 forms the overall inspection platform, and two slide rails 6 enable parallel operation of inspection and assembly, improving work efficiency. A pusher 3 propels the sample container 2 along a circular conveyor line, allowing the sample to pass sequentially under the first camera 4 and the second camera 5, where the cameras capture multi-angle images for defect detection. A moving component 10 moves the moving block 8, transferring the sample container 2. A suction block 13, under the action of a lifting cylinder 16, can flexibly adjust its position to assist in the inspection operation. A limiting rod 17 restricts the position of the frame 7, ensuring the stability and accuracy of the entire inspection process. Compared to existing manual inspection and traditional single-camera inspection methods, this device overcomes the problems of low efficiency and error-proneness in manual inspection and the incompleteness of traditional single-camera inspection, greatly improving the accuracy and efficiency of water supply valve appearance defect detection, effectively ensuring product quality and reducing production costs.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
