Description

Technical Field

[0001] This utility model relates to the technical field of regular polyhedral workpiece inspection devices, and more specifically, to a self-driven inspection device for regular polyhedra. Background Technology

[0002] In various important application scenarios such as modern industrial manufacturing, intelligent logistics warehousing and transportation, and precision product quality inspection, enterprises typically need to conduct systematic and comprehensive quality inspections on various raw materials, key components, semi-finished parts, and other important items to ensure product quality and process reliability. These quality inspections cover multiple dimensions, including but not limited to: detecting surface defects, measuring precise dimensions of key parts, non-destructive testing of internal structures, and verifying the reliability of material properties. Through these rigorous inspection processes, product quality can be effectively controlled, production risks reduced, and overall operational efficiency improved.

[0003] In existing technologies, multi-axis robotic arms are commonly used in conjunction with vision guidance or preset programs to grasp and flip items. However, this method of robotic arm flipping is costly, requires significant investment in the robot itself and its supporting systems, and has speed limitations. The process of grasping, moving, flipping, and returning the robotic arm is time-consuming, making it difficult to meet the needs of high-speed production lines. Furthermore, it requires a large workspace and safety barriers to protect the robotic arm, and may cause scratches or crush damage when grasping workpieces. Therefore, inventing a self-driven flipping inspection device for regular polyhedra to solve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a self-driven flipping and inspection device for regular polyhedra, which aims to solve the problems of high cost of robotic arm flipping and large investment in robot body and supporting system.

[0005] This utility model is implemented as follows: This utility model provides a self-driven flipping and inspection device for regular polyhedra, including a support frame and a detection mechanism, a flipping mechanism and a feeding mechanism disposed on the support frame, wherein the height of the support frame decreases gradually towards the feeding end; The four detection mechanisms are installed above the support frame, and the four detection mechanisms are at different heights. The detection mechanisms detect the outer wall of the workpiece. The flipping mechanism is installed on the support frame near the two detection mechanisms, and the flipping mechanism flips over qualified workpieces. The feeding mechanism is installed at the lowest point of the support frame, and the feeding mechanism feeds workpieces of different masses.

[0006] Preferably, the detection mechanism includes a conveyor table, a fixed plate, a motor base, a fixed guide rail, an adjusting plate, a drive shaft, and a drive belt. Two fixed plates are installed on the outer walls of both sides of the conveyor table. A fixed guide rail is installed below the fixed plate near the front end of the conveyor table, and three fixed guide rails are installed below the fixed plate at the other end. An adjusting plate is installed on the outer wall of the conveyor table near the space between the two fixed plates. An adjusting motor is installed above the adjusting plate. A rotating seat is installed at the output end of the adjusting motor, and an adjusting guide rail is installed below the rotating seat.

[0007] Preferably, the motor base is mounted on the side wall of one of the fixed plates, a conveyor motor is mounted on the outer wall of the motor base, a drive toothed pulley is fixedly connected to the output end of the conveyor motor, two symmetrical drive shafts are mounted on the inner wall of the conveyor table, a drive belt is mounted between the two drive shafts, a driven toothed pulley is mounted on one end of one of the drive shafts, and a toothed belt is connected between the driven toothed pulley and the drive toothed pulley.

[0008] Preferably, a fixed frame is installed on the side wall of the conveyor table, a camera is installed on the upper inner wall of the fixed frame, and a supplementary light is installed on the side wall of the conveyor table away from the fixed frame.

[0009] Preferably, the flipping mechanism includes a connecting plate, a limiting plate, a defective product track, and a flipping track. The connecting plate is designed to be inclined, and its two ends are respectively installed on the outer walls of the two side conveyor platforms. The two defective product tracks are installed on both sides of the flipping track. The defective product track and the flipping track correspond one-to-one with three fixed guide rails. The limiting plate is installed on the outer wall of the connecting plate near the flipping track.

[0010] Preferably, the unloading mechanism includes an unloading platform, a positioning plate, a good product limiting frame, a defective product limiting frame, a defective product unloading plate, and a good product unloading plate. The unloading platform and the conveyor platform have the same overall structure. The positioning plate is installed above the unloading platform. The lower side of the positioning plate is fixedly connected to one end of the good product limiting frame and the defective product limiting frame, respectively. The defective product unloading plate and the good product unloading plate are respectively installed on the side wall of the unloading platform.

[0011] The beneficial effects of this utility model are: The inspection agency, in conjunction with the flipping mechanism, can quickly determine product quality and automatically classify good and defective products, achieving fully automatic classification of workpieces and improving the efficiency of inspection and classification. At the same time, the conveyor belt provides initial kinetic energy, and the subsequent flipping is completed entirely by gravitational potential energy conversion and inertia, eliminating the need for active drive components, which reduces manufacturing costs, energy consumption, and maintenance difficulty. Meanwhile, the flipping track of this solution, through its spiral / curved geometric structure design, utilizes the angular features of regular polygons and the torque changes at the track contact points to achieve stable self-driven flipping. It requires no shape customization, making it more versatile. Furthermore, it seamlessly connects with the unpowered track via a conveyor belt, allowing the workpiece to continuously flow and flip under gravity. This results in a faster inspection cycle, making it more suitable for high-speed production line requirements. The low-damage flipping allows conventional surface contact to replace point contact, avoiding the indentation left by mechanical gripping on the workpiece surface that causes localized damage. This makes it suitable for products with high surface quality requirements, thus expanding its applicability. Attached Figure Description

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example, refer to Figures 1-3 A self-driven inspection device for regular polyhedra includes a support frame 1 and a detection mechanism 2, a flipping mechanism 3 and a feeding mechanism 4 disposed on the support frame 1. The height of the support frame 1 decreases gradually towards the feeding end. Four inspection mechanisms 2 are installed above the support frame 1. The four inspection mechanisms 2 are at different heights and inspect the outer wall of the workpiece. The flipping mechanism 3 is installed on the support frame 1 near the two detection mechanisms 2. The flipping mechanism 3 flips over qualified workpieces. The feeding mechanism 4 is installed at the lowest point of the support frame 1, and the feeding mechanism 4 feeds workpieces of different masses.

[0017] Further; the testing mechanism 2 includes a conveyor table 21, a fixed plate 22, a motor base 23, fixed guide rails 24, an adjusting plate 25, a drive shaft 28, and a drive belt 29. Two fixed plates 22 are installed on the outer walls of both sides of the conveyor table 21. A fixed guide rail 24 is installed below the fixed plate 22 near the front end of the conveyor table 21, and three fixed guide rails 24 are installed below the fixed plate 22 at the other end. An adjusting plate 25 is installed on the outer wall of the conveyor table 21 near the two fixed plates 22. An adjusting motor 251 is installed above the adjusting plate 25. A rotating seat 26 is installed at the output end of the adjusting motor 251. An adjusting guide rail 27 is installed below the rotating seat 26. The motor base 23 is installed on the side wall of one of the fixed plates 22. A conveying motor 231 is installed on the outer wall of the motor base 23. A drive toothed pulley 232 is fixedly connected to the output end of the conveying motor 231. Two drive shafts 28 and 29 are installed on the inner wall of the conveyor table 21. A symmetrical drive shaft 28 is installed between two drive shafts 28. A driven toothed pulley 281 is installed at one end of one of the drive shafts 28. A toothed belt 282 is connected between the driven toothed pulley 281 and the driving toothed pulley 232. A fixed frame 211 is installed on the side wall of the conveyor table 21. A camera 212 is installed on the upper inner wall of the fixed frame 211. A supplementary light 213 is installed on the side wall of the conveyor table 21 away from the fixed frame 211. The flipping mechanism 3 includes a connecting plate 31, a limiting plate 311, a defective product track 32, and a flipping track 33. The connecting plate 31 is designed to be inclined. The two ends of the connecting plate 31 are respectively installed on the outer walls of the two conveyor tables 21. Two defective product tracks 32 are installed on both sides of the flipping track 33. The defective product track 32 and the flipping track 33 correspond one-to-one with three fixed guide rails 24. A limiting plate 311 is installed on the outer wall of the connecting plate 31 near the flipping track 33.

[0018] It should be noted that: the workpiece is initially conveyed via the uppermost conveyor table 21 of the support frame 1. Initially, the workpiece moves along the central axis of the detection mechanism 2 via the fixed guide rail 24. As it passes through the area captured by the camera 212, the camera 212 captures an image of the workpiece's upper surface and transmits the image signal to the terminal for detection (the camera 212's image capture and signal transmission is existing technology and will not be elaborated upon here). Then, it is determined whether the surface is qualified. If the detection is qualified, the workpiece continues to move along the central axis and is conveyed to the next stage via the fixed guide rail 24 at the end of the conveyor table 21. Conversely, when burrs are detected on the surface of a workpiece, the adjusting motor 251 starts to control the adjusting guide rail 27 to rotate to one side, thereby guiding the workpiece closer to the side wall of the conveyor table 21. At the same time, when cracks or dimensional defects are detected on the surface of a workpiece, the adjusting motor 251 starts to control the adjusting guide rail 27 to rotate to the other side, thereby moving subsequent workpieces to the other side wall of the conveyor table 21. This ensures that the two types of defective products move on opposite sides of the good products, thus quickly distinguishing between good products and the two types of defective products, and allowing them to be conveyed through different paths. The workpiece then falls into the flipping mechanism 3 below. Good workpieces enter the flipping track 33, which is a spatial spiral channel derived from a cuboid base. The inner cavity of the track is a square channel with a constant cross-section. The central axis of the channel along the length direction is a cylindrical spiral with a total rotation angle of 90 degrees. This forces the workpiece to rotate 90 degrees and flip over when passing through the flipping track 33. After that, it enters the subsequent inspection mechanism 2 to repeatedly inspect different surfaces. This is repeated three times until all four surfaces pass the inspection, at which point it is defined as a good product. At the same time, the defective products on both sides enter the subsequent inspection mechanism 2 through the defective product track 32 and are conveyed along the inner wall of the conveyor table 21. During this process, they are not inspected, thus ensuring that good and defective products are unloaded at different positions. In conjunction with the inspection mechanism 2, good and defective products are automatically classified while quickly judging product quality, realizing fully automatic classification of workpieces and improving the efficiency of inspection and classification. At the same time, the initial kinetic energy is provided by the conveyor belt, and the subsequent flipping is completed entirely by gravitational potential energy conversion and inertia, eliminating the need for active drive components, which reduces manufacturing costs, energy consumption, and maintenance difficulty. Furthermore, the existing flipping mechanism 3 requires customization for specific shapes, resulting in poor versatility. The track in this solution is designed with a spiral / curved geometry, utilizing the angular features of regular polygons and the torque changes at the track contact points to achieve stable self-driven flipping. It does not require shape customization, making it more applicable. In addition, it is seamlessly connected to the unpowered track via a conveyor belt, allowing the workpiece to continuously flow and flip under gravity. This results in a faster detection cycle, making it more suitable for high-speed production line requirements. The low-damage flipping allows conventional surface contact to replace point contact, avoiding the indentation left by mechanical gripping on the workpiece surface that causes local damage. It is suitable for products with high surface quality requirements, thus expanding the scope of application.

[0019] Furthermore, the unloading mechanism 4 includes an unloading platform 41, a positioning plate 42, a good product limiting frame 43, a defective product limiting frame 44, a defective product unloading plate 45, and a good product unloading plate 46. The unloading platform 41 and the conveyor platform 21 have the same overall structure. The positioning plate 42 is installed above the unloading platform 41. The lower side of the positioning plate 42 is fixedly connected to one end of the good product limiting frame 43 and the defective product limiting frame 44, respectively. The defective product unloading plate 45 and the good product unloading plate 46 are respectively installed on the side wall of the unloading platform 41.

[0020] It should be noted that: the channel between the good product limit frame 43 and the unloading table 41 constitutes the serious defective product unloading channel, which is used to transport defective products with surface cracks and dimensional defects; the channel between the good product limit frame 43 and the defective product limit frame 44 forms the good product unloading channel, which is used to unload qualified good products; and the channel between the defective product limit frame 44 and the unloading table 41 is used to transport defective products with burrs.

[0021] After inspection, the workpieces are conveyed to the unloading mechanism 4, where they are unloaded along a specific unloading channel. Good workpieces are unloaded through the good workpiece unloading plate 46, severely defective workpieces are unloaded through the defective workpiece unloading plate 45, and defective workpieces with burrs are conveyed through the unloading table 41 to the subsequent grinding device for grinding. This process quickly collects and classifies the workpieces, further improving classification efficiency. It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
