Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a rapid visual testing device for plastic products. Background Technology

[0002] Visual inspection is a rapidly developing branch of artificial intelligence. It is an automated inspection device based on machine vision recognition technology that can replace manual labor and accurately and quickly complete the inspection of product appearance defects. It is currently widely used in the automatic inspection of industrial fields. At present, most product inspection methods use fixed cameras to collect images of the product from above and transmit them to a dedicated image processing system. However, this method has a relatively single inspection angle. When inspecting some products with complex and irregular surfaces and concave and convex structures, such as building blocks or clothes hanger clips, there will be some blind spots in the inspection. It is impossible to scan the product surface evenly, resulting in inaccurate inspection results and affecting the judgment of product quality. Therefore, this invention provides a rapid visual inspection device for plastic products to meet the needs. Utility Model Content

[0008] Optionally, an external gear is fixedly connected to the inner wall of the inner frame.

[0009] Optionally, a sleeve gear meshes with the inner circumference of the gear teeth and the outer circumference of the external gear, and a connecting rod is rotatably connected to the inner wall of the sleeve gear.

[0010] Optionally, a camera is fixedly connected to one end of the connecting rod, and a guide plate is fixedly connected to the outer wall of the connecting rod, the guide plate being adapted to the second guide rail.

[0011] Optionally, a rotating plate is rotatably connected to the inner wall of the second guide rail, and a protrusion is fixedly connected to the end of the rotating plate.

[0026] like Figures 1 to 3 As shown, an embodiment of this utility model provides a rapid visual inspection device for plastic products, including a frame 1, a conveyor belt 2 on the top of the frame 1, a mounting platform 3 fixedly connected to the outer wall of the frame 1, a motor 4 and a bushing 5 fixedly connected to the top of the mounting platform 3, and a worm gear 6 fixedly connected to the end of the motor 4; and a detection component for scanning the surface of the product. The detection component is connected to the mounting platform 3. The detection component allows the camera 18 to move in a circular motion around the product to be inspected, acquiring images of the product from multiple angles, thereby uniformly covering all areas of the product surface, effectively eliminating blind spots, and improving detection accuracy and efficiency.

[0027] As one implementation method in this embodiment, such as Figures 2 to 5As shown, the detection assembly includes an outer frame 7 fixedly connected to the top of the mounting platform 3. A connecting plate 8 is fixedly connected to the outer wall of the outer frame 7, and an inner frame 9 is fixedly connected to the inner wall of the connecting plate 8. A first guide rail 10 is fixedly connected to the inner wall of the outer frame 7, and a gear ring 11 is slidably connected to the outer wall of the first guide rail 10. Second guide rails 12 are fixedly connected to both the outer wall of the outer frame 7 and the outer wall of the inner frame 9. Worm gear teeth 13 are formed on the outer wall of the gear ring 11, and gear teeth 14 are formed on the inner wall of the gear ring 11. An external gear 15 is fixedly connected to the inner wall of the inner frame 9. A sleeve gear 16 meshes with the inner circumference of gear 14 and the outer circumference of gear 15. A connecting rod 17 is rotatably connected to the inner wall of the sleeve gear 16. A camera 18 is fixedly connected to one end of the connecting rod 17. A guide plate 19 is fixedly connected to the outer wall of the connecting rod 17. The guide plate 19 is adapted to the second guide rail 12. The above-mentioned detection component is driven by two motors 4 and two worm gears 6. During operation, the worm gears 6 rotate in opposite directions to ensure that the detection component can quickly and symmetrically scan the product to be detected during movement. The rod 6 and the worm gear 13 cooperate with each other. The central axis of the second guide rail 12 is the same as that of the gear ring 11, ensuring that the camera 18 can move stably along the circumferential path. The bushing 5 provides support and guidance when the worm 6 rotates, ensuring the coaxiality and stability of the worm 6 rotation. The worm 6 is driven by the motor 4 to rotate. The rotation of the worm 6 will mesh with the worm gear 13, thereby driving the gear ring 11 to slide and rotate along the first guide rail 10 on the inner wall of the outer frame 7. When the gear ring 11 rotates, the gear teeth 14 on its inner wall will mesh with the bushing gear 16, driving the bushing... The shaft gear 16 moves in a circular motion along the external gear 15 inside the inner frame 9. During this process, the connecting rod 17 moves synchronously with the movement of the shaft gear 16, causing the camera 18 to move synchronously. During the movement, the guide plate 19 on the outer wall of the connecting rod 17 moves along the second guide rail 12. Since the connecting rod 17 is rotatably connected to the inner wall of the shaft gear 16, the connecting rod 17 will also rotate while being driven by the shaft gear 16, ensuring that the lens of the camera 18 is always aligned with the central axis of the outer frame 7, thereby improving the stability and reliability of image acquisition.

[0028] In this embodiment, as Figures 5 to 7As shown, a rotating plate 20 is rotatably connected to the inner wall of the second guide rail 12. A protrusion 21 is fixedly connected to the end of the rotating plate 20, and a deformation plate 22 is fixedly connected to the outer wall of the rotating plate 20. A spherical head 23 is fixedly connected to the end of the deformation plate 22. The rotating plate 20, protrusion 21, deformation plate 22, and spherical head 23 are integrally manufactured. The connection point between the deformation plate 22 and the rotating plate 20 is a curved elastic structure. Since the rotating plate 20, protrusion 21, deformation plate 22, and spherical head 23 are integrally manufactured, they can be uniformly injection molded in actual production. The structure is simple, the injection molding cost is low, and it is easy to manufacture. Because the connection point between the deformation plate 22 and the rotating plate 20 is a curved elastic structure, when the connecting rod 17... When the guide plate 19 on the outer wall moves along the second guide rail 12 onto the rotating plate 20, the rotating plate 20 will move closer to the inner wall of the second guide rail 12 due to the pressure of the guide plate 19. During the process of the rotating plate 20 moving closer to the inner wall of the second guide rail 12, the deformation plate 22 will deform, and the spherical head 23 at its end will move upward along the inner wall of the second guide rail 12 to buffer the impact force when the guide plate 19 slides over the rotating plate 20, providing appropriate inertial compensation for the camera 18, making the camera 18 more stable when changing direction or stopping, and reducing image acquisition deviation caused by sudden motion. The protrusion 21 at the end of the rotating plate 20 can prevent the guide plate 19 from slipping off the second guide rail 12, playing a limiting role and ensuring that the guide plate 19 always moves within the limited range of the second guide rail 12.

[0029] The working principle of the technical solution provided by this utility model is as follows: In use, the product to be inspected can be placed on the conveyor belt 2. The product moves forward with the conveyor belt 2 and enters the shooting range of the camera 18. The motor 4 drives the worm gear 6 to rotate. The rotation of the worm gear 6 will mesh with the worm wheel teeth 13, thereby driving the gear ring 11 to slide and rotate along the first guide rail 10 on the inner wall of the outer frame 7. When the gear ring 11 rotates, the gear teeth 14 on its inner wall will mesh with the sleeve gear 16, driving the sleeve gear 16 to perform circular motion along the external gear 15 in the inner frame 9. During this process, the connecting rod 17 will drive the camera 18 to move synchronously with the movement of the sleeve gear 16. During the movement, the guide plate 19 on the outer wall of the connecting rod 17 will move along the second guide rail 12, thereby causing the camera 18 to scan around the outer periphery of the product in a circular trajectory. When the guide plate 19 on the outer wall of the connecting rod 17 moves along the second guide rail 12, the camera 18 will scan around the outer periphery of the product in a circular trajectory. When the 9 moves along the second guide rail 12 onto the rotating plate 20, the rotating plate 20 will move closer to the inner wall of the second guide rail 12 due to the pressure of the guide plate 19. During the process of the rotating plate 20 moving closer to the inner wall of the second guide rail 12, the deformation plate 22 will deform, and the spherical head 23 at its end will move upward along the inner wall of the second guide rail 12 to buffer the impact force when the guide plate 19 slides over the rotating plate 20, providing appropriate inertial compensation for the camera 18, making the camera 18 more stable when changing direction or stopping. The protrusion 21 at the end of the rotating plate 20 can prevent the guide plate 19 from slipping off the second guide rail 12, playing a limiting role and ensuring that the guide plate 19 always moves within the limited range of the second guide rail 12. After scanning one product, the motor 4 reverses to scan the next product. The specific operation steps are the same as the above process, and will not be described in detail.

[0030] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
