Description

Technical Field

[0001] This utility model relates to the field of visual recognition sorting equipment technology, specifically a sorting device based on visual recognition. Background Technology

[0002] With the continuous development of industrial automation technology, sorting devices are being used more and more widely in various fields, especially in logistics, manufacturing, food processing and recycling. Automated sorting systems are gradually becoming key equipment for improving production efficiency and reducing labor costs. In traditional sorting devices, manual or simple mechanical conveying devices are usually used for sorting operations, which suffers from problems such as low sorting efficiency, high labor costs and insufficient accuracy.

[0003] A search revealed that application number 202222665693.9 discloses a visual recognition-based sorting device, including a conveyor belt and frames mounted on both sides of the conveyor belt. The frames are equipped with a separating mechanism, wherein the separating mechanism includes a first separating plate and a second separating plate; the first end of the first separating plate has a protrusion, and the first side of the second separating plate has several protrusions. This visual recognition-based sorting device utilizes the second separating plate to adjust the distance between its second end and the first separating plate. The first separating plate also has protrusions to separate parts and create spacing, preventing parts from clustering together and interfering with visual recognition, thus improving the visual recognition rate. Furthermore, the protrusions on the second separating plate cause parts to contact the protrusions and rotate, squeezing them towards adjacent parts to create gaps, preventing jamming caused by parts entering the separating mechanism in parallel.

[0004] Existing visual recognition sorting systems often have some problems. The single camera on some devices is greatly affected by ambient light, especially the color difference resolution capability of reflective materials (such as metal and plastic), which leads to large errors in the detection process and cannot meet the requirements of high-precision sorting. Conventional conveyor belts can only capture images of the top of the material, and bottom defects are easy to miss. Manual flipping detection is inefficient.

[0005] Therefore, those skilled in the art have provided a sorting device based on visual recognition to solve the problems mentioned in the background art. Utility Model Content

[0042] The drive assembly includes a servo motor 10 fixedly mounted on one side of the push plate 8 via a support plate. A pinion 11 is fixedly connected to the output end of the servo motor 10. The servo motor 10 drives a large gear 12 through the output pinion 11, thereby driving the connecting shaft 9 to rotate, thus completing the precise control of the push plate 8 and the clamping assembly.

[0043] The clamping assembly includes a support plate 13 fixedly installed at the bottom of the connecting shaft 9.

The electric grippers 14 are connected to an external power source through a conductive slip ring, which ensures 360° unrestricted rotation.

[0044] The pushing assembly includes a cylinder 15 fixedly mounted on the front of the conveyor table 1 via a tripod. The telescopic end of the cylinder 15 is fixedly connected to a dropping plate 16. The pushing assembly is used for sorting.

The clamping block 17 and the recognition frame 3 are detachably connected by bolts. The adjustment assembly allows the installation and height of the vision recognition device 19 to be adjusted according to the different characteristics of the material. Through the sliding connection and detachable bolts, the adjustment assembly provides flexibility and allows for fine-tuning of the vision recognition system to adapt to the recognition needs of different materials.

[0046] The receiving assembly includes a receiving rack 20, two receiving boxes 21, and an extension plate 22. The receiving rack 20 is located on the other side of the conveyor table 1. The extension plate 22 is fixedly installed on the back of the conveyor table 1 and located on one side of the adjusting frame 5. The two receiving boxes 21 are placed on top of the receiving rack 20. The receiving assembly is used to store sorted materials. The receiving rack 20 supports the receiving boxes 21 and ensures that the materials can fall smoothly into the correct receiving box 21 during the sorting process through the extension plate 22.

[0047] Two color analyzers 23 are fixedly installed on the front of the conveyor 1. A camera 24 is fixedly installed on the front of the conveyor 1 and below the electric gripper 14. A computer 25 is installed inside the conveyor 1 via a bracket. The color analyzers 23 are used to detect the color of the materials in real time. This device can identify the color characteristics of the materials and ensure that materials with similar colors are not misclassified during the sorting process. The camera 24 works with the color analyzers 23 to capture the image information of the materials. By processing and analyzing the images of the materials, the camera 24 provides data to the computer 25 to ensure that the materials are accurately identified and classified. The computer 25 is the control center of the entire sorting system. It is responsible for receiving data from devices such as the vision recognition device 19, color analyzers 23, and camera 24, processing and analyzing it in real time, and outputting results according to preset standards to command other mechanical components (such as gripping components, pushing components, etc.) to perform sorting tasks.

[0048] The working principle of this utility model is as follows: First, the worker pours the parts into the vibrating conveyor plate 2. Then, the device is connected to the power supply, which starts the vibrating conveyor plate 2 and moves the materials into the conveyor table 1 according to the required intervals and arrangements, thereby avoiding material accumulation and misalignment problems and improving the recognition accuracy of the visual recognition equipment. Then, the conveyor belt on the conveyor table 1 is started, and the camera 24, visual recognition instrument 19, and color analyzer 23 are connected to the computer 25. Then, when the part passes the position of the first color analyzer 23, the device records it and transmits the side information to the computer 25 for comparison. Yes, then the position information of the part is recorded, and the conveyor belt continues to transport it into the light-shielding shell 4. The vision recognition device 19 analyzes the information of the part. At this time, in order to adapt to the recognition needs of materials of different heights and achieve better recognition accuracy and efficiency, the fixing bolts on the clamping block 17 can be loosened so that the clamping block 17 no longer clamps the recognition frame 3. Then the fixing frame 18 is adjusted to a suitable height, and the fixing bolts are screwed into the clamping block 17. This allows the distance between the vision recognition device 19 and the part to be adjusted so that the recognition angle and distance can be adjusted according to the height of the material to ensure that it is always at the optimal recognition height.

[0049] Then, the data recognized by the vision recognition device 19 is transmitted to the computer 25 and recorded for comparison. The part then travels along the conveyor 1 to the position of the second color analyzer 23, where a secondary calibration is performed before flipping. At this time, the device records and prepares for clamping. When the second color analyzer 23 passes the two parts, the parts are positioned above the two electric grippers 14. The conveyor 1 then stops, and the electric telescopic rod 7 starts, its extension and retraction causing the push plate 8 and support plate 13 to move downwards synchronously. The electric grippers 14 then clamp the part, and the electric telescopic rod 7 retracts. At this point, the servo motor 10 is activated, causing its output to drive the pinion 11 to rotate. The large gear 12 drives the connecting shaft 9 to rotate, which in turn drives the support plate 13 and the electric gripper 14 to rotate. This causes the gripped part to pass over the camera 24, allowing for visual recognition of the bottom of the part. After rotating once, the part is placed down, and the conveyor 1 continues to transport it. The computer 25 marks and records the defective products. When the computer moves to the drop plate 16, the defective products are pushed into one of the receiving boxes 21 by the drop plate 16 at the telescopic end of the cylinder 15. The qualified products fall into the other receiving box 21 along the conveyor 1, thus completing the visual recognition sorting.

[0050] 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.
