Description

Technical Field

[0001] This utility model relates to the field of surface defect detection technology for parts, and more specifically, to a device for monitoring surface cracks in components. Background Technology

[0002] In the industrial manufacturing sector, surface defect detection of parts is a crucial step in ensuring product quality. With the development of machine vision technology, vision-based defect detection methods are gradually replacing traditional manual inspection, significantly improving efficiency and accuracy. Existing technologies, such as the surface defect detection mechanism disclosed in Chinese Patent Publication No. (CN219348617U), utilize components such as a guide cylinder, extension rod, lampshade, and LED lights to adjust the light source and reduce glare on the part surface. Simultaneously, the auxiliary light, worm gear, and worm structure allow for flexible adjustment of the auxiliary light angle, thereby improving the image capture effect on the part surface. Furthermore, the device facilitates light adjustment through a handwheel and hexagonal nut structure, further enhancing its practicality. However, despite the advantages of the aforementioned technologies in light source optimization and image capture, significant technical shortcomings remain. For example, when inspecting the surface of a part, this device can only inspect one side of the part at a time. If the other side needs to be inspected, the part must be manually flipped and repositioned onto the inspection device. This process not only increases operational complexity but also significantly reduces inspection efficiency, especially in large-scale production scenarios, making it difficult to meet the demand for efficient inspection. Therefore, there is an urgent need for a surface defect inspection mechanism that can automatically complete multi-faceted inspection of parts to overcome the inefficiency of existing technologies and improve the level of automation and overall performance of inspection. Summary of the Invention

[0003] The purpose of this invention is to provide a device for monitoring surface cracks in components, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, an automatic flipping inspection mechanism for detecting surface defects in parts is provided, comprising a transport table, an inspection table, and a flipping assembly. The transport table is used to transport the parts to be inspected, and the flipping assembly is mounted on it to achieve automatic flipping of the parts. The inspection table is located above the transport table, with a supplementary light and a CCD vision camera installed at the top of its inner cavity, and laser sensors arranged on both sides of the inner cavity. A microcontroller is also installed outside the inspection table, controlling the extension and retraction of a hydraulic rod. Further, the flipping assembly includes a first anchor point, a second anchor point, a third anchor point, a flipping rod, a hydraulic rod, and their linkage structure. The first anchor point is rotatably connected to a first connecting rod, the second anchor point is rotatably connected to a second connecting rod, and the third anchor point is rotatably connected to the output end of the hydraulic rod. The other end of the hydraulic rod is rotatably mounted on the second connecting rod. The flipping rod has an L-shaped structure, with its long side fixedly connected to a pin, which is rotatably connected to the other end of the first connecting rod. The other end of the second connecting rod is provided with a roller, which is rollingly connected to the short side of the flipping rod. Two flipping rods are included, located on opposite sides of the transport table, and are fixedly connected by a fixing rod.

[0005] Furthermore, the design of the flipping assembly is the core innovation of this invention. Automatic flipping of parts is achieved through a hydraulic rod and the flipping assembly, eliminating the need for manual intervention and significantly improving inspection efficiency. Specifically, the flipping rod has an L-shaped structure, with its long side fixedly connected to a pin. The pin is rotatably connected to the other end of the first connecting rod, and a roller is provided at the other end of the second connecting rod, rollingly connected to the short side of the flipping rod. This design ensures that the flipping rod can smoothly flip the parts under the drive of the hydraulic rod, while also ensuring that the parts do not fall off or shift during the flipping process.

[0006] Furthermore, the hydraulic rod, as the core driving component, drives the tilting rod to rotate through its extension and retraction. One end of the hydraulic rod is connected to the transport platform via a third anchor point, and the other end is linked to the tilting rod via a second connecting rod. The extension and retraction of the hydraulic rod directly drives the tilting rod to rotate, thereby achieving efficient rotation of the parts.

[0007] Furthermore, the laser sensor is used to sense the position of the part and trigger the action of the flipping assembly. When the part passes the laser sensor, it blocks the light, and the laser sensor receiver cannot receive the light emitted by the transmitter, triggering the hydraulic rod to start.

[0008] Furthermore, the design of the flipping assembly is highly versatile. The flipping rod has an L-shaped structure, with its long side connected to the first connecting rod via a pin and its short side connected to the second connecting rod via a roller. This design allows the flipping rod to flip flexibly under the drive of a hydraulic rod, making it suitable for parts of different shapes and sizes. In particular, the length and angle of the flipping rod can be adjusted according to actual needs to adapt to different inspection scenarios.

[0009] Furthermore, the tilting assembly is integrated with the transport platform, saving space and facilitating integration into existing testing equipment. The various components of the tilting assembly are fixed to the transport platform by bolts or welding, ensuring the stability and reliability of the overall structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Automatic part flipping via hydraulic rods and a flipping assembly eliminates the need for manual intervention, significantly improving inspection efficiency. In particular, the flipping assembly's design avoids operational errors that can be introduced by manual flipping, ensuring more accurate inspection results. The flipping assembly is highly versatile, adaptable to parts of different shapes and sizes, expanding its applicability. Its integrated design with the transport table saves space and facilitates integration into existing inspection equipment. Furthermore, the application of laser sensors ensures the accuracy and reliability of the flipping process, further improving inspection precision. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0014] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” and “described” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in this specification means the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0015] Please see Figure 1-4 As shown, a component surface crack monitoring device and an automatic flipping inspection mechanism for detecting surface defects in components are provided. The overall structure includes a transport table 1, an inspection table 2, and a flipping assembly. The transport table 1 is made of metal, and its upper surface is equipped with a conveyor belt to ensure the smooth movement of the component to be inspected. The inspection table 2 is located above the transport table 1, and its interior is hollow to form an inspection cavity. A supplementary light 15 and a CCD vision camera 16 are installed on the top, and laser sensors 14 are symmetrically arranged on both inner walls. The installation angle of the laser sensors 14 is precisely calculated so that they can accurately sense the position of the component and trigger the hydraulic rod 7 to start. The flipping assembly is installed on the transport table 1 to realize the automatic flipping function of the parts during the inspection process. The inspection table 2 is also equipped with a microcontroller 3. During the inspection process, when the receiving end of the first set of laser sensors 14 cannot receive the light from the transmitting end, the microcontroller 3 controls the hydraulic rod 7 to extend, thereby realizing the flipping operation of the parts. After the flipping operation is completed, when the parts are transported to the position of the second set of laser sensors 14 under the action of the transport table 1, the microcontroller 3 controls the hydraulic rod 7 to retract and make the flipping assembly return to the initial state.

[0016] The flipping assembly consists of a first anchor point 8, a second anchor point 9, a third anchor point 10, a flipping rod 4, a hydraulic rod 7, and their linkage structure. The first anchor point 8 is fixed to one side of the transport platform 1 and rotatably connected to the first connecting rod 5 via a pin. The second anchor point 9 is also fixed to the transport platform 1 and rotatably connected to the second connecting rod 6. The third anchor point 10 is rotatably connected to the output end of the hydraulic rod 7, and the other end of the hydraulic rod 7 is rotatably connected to the second connecting rod 6 via a pin. The flipping rod 4 has an L-shaped structure; its long side is rotatably connected to the other end of the first connecting rod 5 via a pin 12, while its short side rolls in contact with the roller 11 on the second connecting rod 6. The two flipping rods 4 are located on opposite sides of the transport platform 1 and move synchronously via a fixing rod 13.

[0017] Work process: The part to be inspected enters the inspection area via transport table 1. The part is placed on the guide rail of transport table 1 and moved forward by an external drive device. When the part passes inspection table 2, the top supplementary light 15 provides a uniform light source to the inspection area, and the CCD vision camera 16 takes an initial image of the part's surface. At this time, the laser sensor 14 is in standby mode, emitting light from its emitter and waiting for the receiver to receive the signal.

[0018] When the component passes the laser sensor 14, it blocks the light, preventing the receiver from receiving the light emitted by the transmitter. This change triggers the hydraulic rod 7 to activate, and the output end of the hydraulic rod 7 begins to extend. The extension of the hydraulic rod 7 is transmitted to the second link 6 through the third anchor point 10, causing the second link 6 to rotate around the second anchor point 9. Simultaneously, the second link 6 drives the roller 11 to roll along the short side of the flipping rod 4, thereby changing the flipping rod 4 from its initial state to its flipped state.

[0019] During the flipping process, the long side of the flipping rod 4 rotates around the pin 12, lifting the part from one side of the transport table 1 and flipping it to the other side. The design of the flipping rod 4 ensures that the part remains stable during the flipping process, preventing it from falling off or shifting due to a shift in the center of gravity. The rolling contact between the short side of the flipping rod 4 and the roller 11 reduces friction, making the flipping action smoother.

[0020] After the part is flipped, it slides off the flipping rod 4 and returns to the guide rail of the transport table 1. Driven by the transport table 1, the part continues to move forward. At this time, the CCD vision camera 16 in the inspection table 2 takes a picture of the other side of the part, completing a comprehensive inspection of the part's surface.

[0021] Subsequently, when the part is transported to the position of the second set of laser sensors 14 by the transport platform 1, the microcontroller 3 controls the output end of the hydraulic rod 7 to retract, driving the second connecting rod 6 to rotate in the opposite direction, so that the flipping rod 4 returns to its initial state. The reset action of the flipping assembly is realized through the precise control of the hydraulic rod 7, ensuring that the flipping rod 4 can accurately return to its original position to await the inspection of the next part.

[0022] Two sets of laser sensors 14 are symmetrically arranged at the entrance and exit ends of the transport platform 1. This symmetrical arrangement not only improves the accuracy of the flipping assembly's movement but also enhances the system's reliability. The installation positions of the laser sensors 14 are precisely calculated, enabling them to accurately sense the position of the parts and trigger the flipping assembly's movement. When the part completely blocks the light from the laser sensor 14, the system determines that the part has reached the designated position and then triggers the hydraulic rod 7 to start.

[0023] The flipping lever 4 is designed with strong versatility. Its long side is connected to the first connecting rod 5 via pin 12, and its short side is connected to the second connecting rod 6 via roller 11. This design allows the flipping lever 4 to flip flexibly under the drive of the hydraulic rod 7.

[0024] The tilting assembly and transport table 1 are integrated into one unit, with all anchor points secured to the transport table 1 by bolts or welding. This design not only saves space but also facilitates integration of the tilting assembly into existing testing equipment. The installation position of the tilting assembly is optimized to ensure that the tilting action does not interfere with the normal operation of the transport table 1. For example, the initial height of the tilting rod 4 is slightly lower than the guide rail plane of the transport table 1 to avoid obstructing the transport of parts.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
