Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology, and in particular to an automatic feeding device based on vision detection. Background Technology

[0002] Manufacturing is the foundational industrial sector of the national economy and one of the most fundamental factors determining a country's development level. Intelligent manufacturing is the integration and deep fusion of advanced manufacturing technologies, information technologies, and artificial intelligence technologies in manufacturing equipment. It represents the next generation of manufacturing technologies for achieving efficient, high-quality, energy-saving, environmentally friendly, and safe and reliable production. In existing manufacturing systems, materials are often automatically loaded and unloaded by using high-precision positioning mechanisms to move them to designated locations, then a gripping mechanism moves to that location to pick up the materials, and finally places them back to the designated location. This process is repeated.

This vision-based automatic loading device uses a vision inspection component to position the product within the vibrating drum using a camera. The camera then transmits the product position to the three-axis robot, which grasps the product. During the robot's grasping motion, another camera takes a picture to identify the product's orientation. The robot then places the product onto a flipping mechanism, controlling the production cycle and improving production efficiency.

[0004] In the device disclosed in the above utility model, the connection between the feeder and the vibrating drum relies on gravity feeding, which can easily cause material jamming when unloading irregularly shaped parts, affecting normal production. Utility Model Content

[0023] 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.

[0024] Reference Figures 1-4 An automatic feeding device based on vision detection includes a workbench 1, on which a pneumatic manipulator 2 and a conveyor belt 3 are mounted. A material support platform 4 is slidably mounted on the side of the workbench 1. Several storage bins 5 are mounted on the material support platform 4. A connecting plate 8 is mounted on the side of the material support platform 4. A drive mechanism 6 corresponding to the several storage bins 5 is mounted on the connecting plate 8. Several distance sensors 7 are mounted on the upper part of the connecting plate 8. The distance sensors 7 and the corresponding drive mechanisms 6 are electrically connected to the same control system.

[0025] In operation, the robotic arm 2 picks up materials from the storage bin 5 and transfers them to the conveyor belt 3, which then transports the materials to the next processing stage. Workpieces are stacked in the storage bin 5. A distance sensor 7 senses the height of the workpiece at the top of the corresponding storage bin 5 and triggers the drive mechanism 6 to operate, ensuring that the workpiece at the top of the storage bin 5 is always at a specific height. This facilitates the robotic arm 2's movement to a specific location for retrieval, effectively reducing the retrieval travel distance. After retrieval, the drive mechanism 6 controls the workpiece in the storage bin 5 to move upwards to a specific height for the next retrieval operation. This achieves orderly workpiece feeding, avoiding the situation where workpieces get stuck in the feeder as in existing technologies, and ensuring the stability of workpiece feeding.

[0026] Specifically, in this embodiment, the storage bin 5 includes a base plate 51, and a plurality of blocking strips 52 are inserted into the base plate 51. The processing parts are restricted on the base plate 51 by the blocking strips 52, so that the storage bin 5 can stably restrict the stacked processing parts on the base plate 51 by setting the blocking strips 52, thereby realizing the orderly stacking of processing parts and ensuring the stability of the processing parts placed on the base plate 51.

[0027] Specifically, in this embodiment, several blocking bars 52 are movably arranged on the material support platform 4, and their positions are limited by bolts, so that the user can adjust the position of the blocking bars 52 according to the specific specifications of the processed parts, so that the storage bin 5 can store processed parts of different specifications, thereby improving the practicality of the device.

[0028] Specifically, in this embodiment, the drive mechanism 6 includes a first servo motor 61 disposed on the top of the connecting plate 8. A threaded rod 62 is connected to the output shaft of the first servo motor 61. The threaded rod 62 is rotatably connected between the material support platform 4 and the connecting plate 8. A moving block 63 is threadedly connected to the threaded rod 62. The moving block 63 is connected to the corresponding base plate 51.

[0029] When the drive mechanism 6 is running, the first servo motor 61 drives the threaded rod 62 to rotate, thereby driving the moving block 63 to move synchronously. The moving block 63 drives the base plate 51 to move vertically, thereby realizing the operation of pushing the workpiece upward by the base plate 51 to a specific height.

[0030] Specifically, in this embodiment, the connecting plate 8 is provided with a plurality of connecting grooves 9, and the moving block 63 is slidably adapted to the corresponding connecting groove 9, so that the moving block 63 can only move vertically along the direction of the connecting groove 9, thereby restricting the moving direction of the moving block 63, and thus ensuring that the base plate 51 always maintains a vertical moving state.

[0031] Specifically, in this embodiment, an L-shaped connecting rod 10 is provided on the workbench 1, and a camera 11 and a flipping mechanism are provided on the L-shaped connecting rod 10. The camera 11 and the flipping mechanism are connected to the same control system, so that the camera 11 can identify the front and back sides of the workpiece on the conveyor belt 3, and trigger the flipping mechanism to run according to production needs, flipping the workpiece so that the side to be processed faces upward, thereby improving the control performance of the device on the workpiece and further meeting more production needs.

[0032] Specifically, in this embodiment, the flipping mechanism includes an electric telescopic rod 12 mounted on the workbench 1. A movable plate 13 is mounted on the output shaft of the electric telescopic rod 12. The movable plate 13 is slidably connected to the L-shaped connecting rod 10. A rotating rod 14 is mounted on the movable plate 13. The rotating rod 14 is driven by a second servo motor 16. A negative pressure suction cup 15 is mounted on the rotating rod 14.

[0033] When the workpiece needs to be flipped, the electric telescopic rod 12 controls the rotating rod 14 to drive the negative pressure suction cup 15 to move downward, and the negative pressure suction cup 15 picks up the workpiece. Then, the electric telescopic rod 12 is controlled to move upward to an appropriate height, and the second servo motor 16 drives the rotating rod 14 to rotate, thereby realizing the flipping of the workpiece. After flipping, the workpiece is placed on the conveyor belt 3 to continue to be conveyed.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
