Description

Technical Field

[0001] This invention relates to the field of sealing ring testing equipment technology, specifically to a sealing ring double-sided testing flipping device. Background Technology

[0002] As a core sealing element in mechanical equipment, pipelines, and instrumentation, the quality of sealing rings directly determines the sealing performance, operational reliability, and service life of equipment. Especially in high-end fields such as aerospace, precision manufacturing, and the automotive industry, even minor defects in sealing rings can lead to leaks, malfunctions, or even safety accidents. Therefore, efficient and accurate quality inspection of sealing rings is crucial. Traditional sealing ring quality inspection relies heavily on manual visual inspection, which is insufficient to meet the inspection needs of large-scale industrial production. Image processing-based quality inspection technology, with machine vision at its core, combines image acquisition, preprocessing, feature extraction, and defect identification to achieve automated, standardized, and high-precision sealing ring quality inspection, becoming the mainstream technology in the current sealing ring inspection field. The core principle of image processing-based sealing ring quality inspection is to capture the surface and contour images of the sealing ring using industrial imaging equipment, convert the image signals into digital signals, and then use computer algorithms to process and analyze the images, extracting the geometric and defect features of the sealing ring. These features are then compared with preset standard parameters to automatically determine whether the sealing ring is qualified and identify the type and level of defects.

[0003] When performing image-based visual inspection of sealing rings, industrial imaging equipment is required to capture images of the sealing rings. After capturing an image of one side, the sealing ring needs to be flipped over, and then an image of the other side needs to be captured. Both sides are imaged for identification, ensuring more comprehensive and accurate recognition. Existing sealing ring flipping equipment typically uses two conveyor belts. The sealing ring is conveyed by the upper conveyor belt and falls onto the lower conveyor belt, automatically flipping over as it falls. However, this method is prone to problems. Adhesion between the sealing ring and the upper conveyor belt during the flipping process cannot guarantee complete flipping, or the sealing ring may collide and flip multiple times, preventing it from being flipped to the correct back side for inspection, thus increasing the risk of missed detections. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problem that existing equipment cannot guarantee the flipping of the sealing ring, leading to the risk of missed detection, and to provide a sealing ring double-sided detection flipping device.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] A double-sided inspection and flipping device for a sealing ring includes a first conveyor belt and a second conveyor belt. The first conveyor belt is located above the second conveyor belt, and a guide plate is provided at one end of the first conveyor belt. A third conveyor belt is located above the second conveyor belt and below the guide plate. One end of the third conveyor belt extends between the first and second conveyor belts and is arranged at a downward inclination. The upper surface of the guide plate is inclined, and the upper end of the guide plate is close to the end of the first conveyor belt. The gap between the upper end of the guide plate and the end of the first conveyor belt is less than the thickness of the sealing ring. The lower end of the guide plate faces the inclined conveying surface of the third conveyor belt. The conveying direction of the third conveyor belt is opposite to that of the first conveyor belt.

[0007] Furthermore, the angle between the conveying surface of the third conveyor belt and the upper surface of the second conveyor belt is less than 30°. This facilitates the smooth transfer of the sealing ring on the third conveyor belt to the second conveyor belt.

[0008] Furthermore, the guide plate is provided with a first groove, which is arranged from the upper end to the lower end of the guide plate, and multiple first grooves are arranged in parallel and at equal intervals. By providing the first groove, the contact area between the sealing ring and the guide plate is reduced, thereby reducing the friction between the sealing ring and the guide plate and facilitating the sliding of the sealing ring off the guide plate.

[0009] Furthermore, the width of the first groove is less than 1 / 3 of the diameter of the sealing ring. This ensures that the bottom of the sealing ring, after passing through the guide plate, falls onto at least three of the first grooves, preventing the sealing ring from tilting and getting stuck in the first grooves, and guaranteeing that the sealing ring slides smoothly.

[0010] Furthermore, the guide plate is hinged to a swing plate, which includes multiple swing pieces located in a first groove. The upper end of the swing plate is hinged to the guide plate, and a pull rod is hinged to one side of the lower end of the swing plate. The end of the pull rod away from the swing plate is eccentrically hinged to the drive wheel of the first conveyor belt. When the drive wheel of the first conveyor belt rotates, it drives the swing plate to swing. After the swing plate swings, the upper edge of the swing plate protrudes from the first groove to intermittently lift the sealing ring.

[0011] Furthermore, the gap between the lower end of the guide plate and the third conveyor belt is greater than the radius of the sealing ring. This allows the sealing ring to flip over when it slides down the guide plate onto the third conveyor belt.

[0012] Furthermore, the angle between the upper surface of the guide plate and the conveying surface of the third conveyor belt is an acute angle. This facilitates the flipping of the sealing ring when it comes into contact with the third conveyor belt.

[0013] Furthermore, a baffle is provided at the end of the first conveyor belt, and the baffle is located on the side of the guide plate away from the first conveyor belt. By providing the baffle, the sealing ring is shielded and protected.

[0014] Furthermore, the distance between the baffle and the guide plate is less than the diameter of the sealing ring and greater than the thickness of the sealing ring.

[0015] Furthermore, one end of the second conveyor belt is provided with an inclined slide plate, and the gap between the end of the slide plate and the second conveyor belt is less than the thickness of the sealing ring; limit plates are provided on both sides of the slide plate, and a slide is formed between the limit plates to accommodate the passage of the sealing ring.

[0016] The present invention provides a double-sided inspection and flipping device for sealing rings, which has the following beneficial effects: the sealing ring is conveyed by a first conveyor belt. After the sealing ring reaches the end, it slides down along the end. During the downward slide, the sealing ring contacts a guide plate. Under the scraping of the guide plate, the sealing ring separates from the first conveyor belt and slides down along the guide plate. When the sealing ring slides down to the third conveyor belt, the bottom of the sealing ring is driven backward by the third conveyor belt, so that the sealing ring flips and adheres to the third conveyor belt. It then slides down onto the second conveyor belt, so that the sealing ring flips onto the second conveyor belt and is conveyed to the inspection platform for inspection. The scraping of the guide plate prevents the sealing ring from sticking to the first conveyor belt and falling off. The rapid rotation of the third conveyor belt drives the bottom of the sealing ring, so that the sealing ring flips, thereby ensuring that the sealing ring is accurately flipped and falls onto the second conveyor belt.

[0025] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] It should be noted that in the embodiments of the present invention, all directional indications (such as up-down-left-right-forward-backward...) are only used to explain the relative positional relationship and movement between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0028] like Figures 1-6 As shown, a double-sided inspection and flipping device for a sealing ring includes a first conveyor belt 1 and a second conveyor belt 2. The first conveyor belt 1 is located above the second conveyor belt 2. A guide plate 3 is provided at one end of the first conveyor belt 1. A third conveyor belt 4 is provided above the second conveyor belt 2 and is located below the guide plate 3. One end of the third conveyor belt 4 extends between the first conveyor belt 1 and the second conveyor belt 2 and is arranged at a downward inclination. The upper surface of the guide plate 3 is inclined. The upper end of the guide plate 3 is close to the end of the first conveyor belt 1, and the gap between the upper end of the guide plate 3 and the end of the first conveyor belt 1 is less than the thickness of the sealing ring 9. The lower end of the guide plate 3 faces the inclined conveying surface of the third conveyor belt 4, and the conveying direction of the third conveyor belt 4 is opposite to the conveying direction of the first conveyor belt 1.

[0029] Using the above technical solution, the sealing ring 9 is conveyed by the first conveyor belt 1. After the sealing ring 9 is conveyed to the end, it slides down along the end. During the downward movement, the sealing ring 9 comes into contact with the guide plate 3. Under the scraping of the guide plate 3, the sealing ring 9 separates from the first conveyor belt 1 and slides down along the guide plate 3. When the sealing ring 9 slides down to the third conveyor belt 4, the bottom of the sealing ring 9 is driven backward by the third conveyor belt 4, causing the sealing ring 9 to flip over and adhere to the third conveyor belt 4. It then slides down onto the second conveyor belt 2, causing the sealing ring 9 to flip over and be conveyed to the detection platform for detection. The scraping of the guide plate 3 prevents the sealing ring 9 from adhering to the first conveyor belt 1 and falling off. The rapid rotation of the third conveyor belt 4 drives the bottom of the sealing ring 9, causing it to flip over, thus ensuring that the sealing ring 9 is accurately flipped over and falls onto the second conveyor belt 2.

[0030] Specifically, the angle between the conveying surface of the third conveyor belt 4 and the upper surface of the second conveyor belt 2 is less than 30°. This facilitates the smooth transfer of the sealing ring 9 on the third conveyor belt 4 to the second conveyor belt 2.

[0031] Specifically, the guide plate 3 has a first groove 31, which is arranged from the upper end to the lower end of the guide plate 3. Multiple first grooves 31 are arranged in parallel and are equidistant from each other. By setting the first groove 31, the contact area between the sealing ring 9 and the guide plate 3 is reduced, thereby reducing the friction between the sealing ring 9 and the guide plate 3 and facilitating the sliding of the sealing ring 9 off the guide plate 3.

[0032] Specifically, the width of the first groove 31 is less than 1 / 3 of the diameter of the sealing ring 9. This ensures that the bottom of the sealing ring 9, after passing through the guide plate 3, falls on at least three of the first grooves 31, preventing the sealing ring 9 from tilting and getting stuck in the first grooves 31, and ensuring that the sealing ring 9 slides down smoothly.

[0033] Specifically, the guide plate 3 is hinged to a swing plate 5, which includes multiple swing pieces 51 located in the first groove 31. The upper end of the swing plate 5 is hinged to the guide plate 3, and a pull rod 6 is hinged to one side of the lower end of the swing plate 5. The end of the pull rod 6 away from the swing plate 5 is eccentrically hinged to the drive wheel of the first conveyor belt 1. When the drive wheel of the first conveyor belt 1 rotates, it drives the swing plate 5 to swing. After the swing plate 5 swings, its upper edge protrudes from the first groove 31, intermittently lifting the sealing ring 9. When the drive wheel of the first conveyor belt 1 rotates, it drives the first conveyor belt 1 to move and transport the sealing ring 9. At the same time, the pull rod 6 drives the swing plate 5 to swing, thereby causing the sealing ring 9 to be intermittently lifted, making the sealing ring 9 slightly shake upward. This causes the sealing ring 9 to intermittently contact the guide plate 3, reducing its friction and facilitating the downward shaking of the sealing ring 9 onto the third conveyor belt 4.

[0034] Specifically, the gap between the lower end of the guide plate 3 and the third conveyor belt 4 is greater than the radius of the sealing ring 9. This allows the sealing ring 9 to flip over when it slides down the guide plate 3 onto the third conveyor belt 4.

[0035] Specifically, the angle between the upper surface of the guide plate 3 and the conveying surface of the third conveyor belt 4 is an acute angle. This facilitates the flipping of the sealing ring 9 when it comes into contact with the third conveyor belt 4.

[0036] Specifically, a baffle 7 is provided at the end of the first conveyor belt 1, and the baffle 7 is located on the side of the guide plate 3 away from the first conveyor belt 1. By providing the baffle 7, the sealing ring 9 is shielded and protected.

[0037] Specifically, the distance between the baffle 7 and the guide plate 3 is less than the diameter of the sealing ring 9 and greater than the thickness of the sealing ring 9. The distance between the baffle 7 and the guide plate 3 is greater than the thickness of the sealing ring 9 to facilitate the passage of the sealing ring 9, and less than the diameter of the sealing ring 9, so that the sealing ring 9 can only slide downwards and cannot be flipped over in the cavity channel formed by the baffle 7 and the guide plate 3, ensuring that the sealing ring conveyed to the second conveyor belt 2 is exactly the same as the sealing ring 9 on the first conveyor belt 1 flipped to the reverse side.

[0038] Specifically, one end of the second conveyor belt 2 is provided with an inclined slide plate 8, the gap between the end of the slide plate 8 and the second conveyor belt 2 being less than the thickness of the sealing ring 9; limit plates 81 are provided on both sides of the slide plate 8, forming a slide channel between the limit plates 81 to accommodate the sealing ring 9. By setting the slide plate 8, the sealing ring 9 slides from the slide plate 8 onto the detection platform for detection when it is conveyed to the end of the second conveyor belt 2. By setting the slide channel, the sealing ring 9 is guided and limited, allowing it to slide to the designated position on the detection platform.

[0039] It should be noted that frames are installed on both sides of the first conveyor belt 1 and the second conveyor belt 2. The frames are equipped with drive wheels that move the first conveyor belt 1, the second conveyor belt 2, and the third conveyor belt 4. Drive motors that drive the corresponding drive wheels of different conveyor belts are installed on the sides of the frames. The conveying directions of the first conveyor belt 1 and the second conveyor belt 2 are opposite. The baffle 7, guide plate 3, and slide plate 8 are all fixed to the frames to maintain relative positional stability.

[0040] The parts not covered in this technical solution can be implemented using existing technologies.

[0041] The foregoing has shown and described the basic principles, main features, and characteristics of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed.
