Description

Technical Field

[0001] This utility model relates to the field of visual sorting platform technology, specifically a 3D / 2D visual sorting platform. Background Technology

[0002] A 3D / 2D vision sorting platform is an automated sorting system that combines 3D and 2D vision technologies. It is widely used in industrial manufacturing, logistics, food processing and other fields for high-precision identification, classification and sorting of objects. However, in scenarios where vision technology is only used for detection, identification and sorting, the 3D and 2D vision cameras are fixedly installed. As a result, the 3D and 2D vision cameras cannot achieve three-dimensional shape and volume scanning of objects, which limits the application scenarios. Therefore, this application proposes a 3D / 2D vision sorting platform to solve the above problems. Utility Model Content

Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and 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 protection scope of this utility model.

[0021] like Figure 1-5As shown, this utility model provides a technical solution: a 3D / 2D vision sorting platform, including a conveyor table 1, a support frame 2 mounted on the rear side of the conveyor table 1, a motor 3 mounted on the top of the support frame 2, and a drive frame 4 mounted on the output shaft of the motor 3. A 3D camera 5 and a 2D camera 6 are mounted on the drive frame 4. The drive frame 4 includes a slide rail 41, a threaded shaft 42, a motor 43, and a slide block 44. The threaded shaft 42 and the motor 43 are installed inside the slide rail 41, and the threaded shaft 42 is connected to a threaded groove on the slide block 44. The 3D camera 5 is mounted at the bottom of the slide block 44, and the 2D camera 6 is mounted at the middle of the lower end of the slide rail 41. The middle of the top of the slide rail 41 is connected to the output shaft of the motor 3. The conveyor belt transports the object forward. Driven by motor 3, the slide rail 41 rotates, causing the 3D camera 5 to move in a circular motion. Driven by motor 43, the threaded shaft 42 rotates, causing the slide block 44 to slide on the slide rail 41, thus moving the 3D camera 5 linearly. This allows for scanning of the object transported on the conveyor platform 1 from different angles, scanning the object's three-dimensional shape and volume. During this process, the 2D camera 6 captures two-dimensional images of the object, analyzing features such as color, shape, and texture. The 2D camera 6 is positioned directly below motor 3, so when motor 3 drives the drive frame 4 to rotate, the 2D camera 6 only rotates, without displacement, ensuring two-dimensional image capture and recognition of the object on the lower conveyor platform 1. Both sides of the front end of the conveyor platform 1... Motor 7 is installed, and rotating frames 8 are mounted on the output shafts of both motors 7. A rotating shaft 9 is mounted on the top of the rotating frame 8 via a bearing, and a push-out frame 10 is mounted on the bottom of the rotating shaft 9. Sliding platforms 11 are installed on both sides of the front end of the conveyor table 1. After capturing the features of the object using 3D camera 5 and 2D camera 6, the object can be divided into three sorting paths based on its features: normal conveying on the front side of the conveyor table 1, and conveying via the two sliding platforms 11 on both sides. When the objects slide out for sorting on both sides, motor 7 can be activated. Motor 7 drives the rotating frames 8 to rotate, causing the push-out frames 10 to move towards the center of the conveyor table 1. When the push-out frames 10 contact the object, they can push the object to one side onto the sliding platform, thus sorting the object. Sliding platforms 11 are installed on both sides of the conveyor table 1. With a centering plate 12, motor 2 7 drives the rotating frame 8 and the ejector frame 10 to reset. After these components are reset, the ejector frame 10 will fit against the centering plate 12. Three ejector rods are installed at the bottom of the top plate, which is mounted on the bottom side of the rotating shaft 9. This allows the ejector frame 10 to rotate and reset around the rotating shaft 9, maintaining parallelism with the conveyor table. This ensures that the ejector frame 10 can fit against one side of the object when it is ejected next. Two ejector frames 10 are fitted against the opposite surfaces of the two centering plates 12. Each ejector frame 10 includes a top plate and three ejector rods. The arrangement of the three ejector rods ensures fit against the object. The middle ejector rod is located on the outer side of the bottom of the top plate, while the two outer ejector rods are located on the inner side of the bottom of the top plate. This allows the three ejector rods to be aligned on an arc.The three push rods can also push an object to move when they are in contact with an object with a curved surface.

[0022] The operational steps for this application are as follows:

[0023] The conveyor belt on the conveyor table 1 transports the object forward. Driven by motor 3, the slide rail frame 41 can rotate, which can drive the 3D camera 5 to make a circular motion. Driven by motor 43, the threaded shaft 42 rotates, which can drive the slide block 44 to slide on the slide rail frame 41, and drive the 3D camera 5 to move linearly, so as to scan the object transported on the conveyor table 1 from different angles, and scan the three-dimensional shape and volume of the object. During this process, the 2D camera 6 can capture the two-dimensional image of the object and analyze its color, shape, texture and other features.

[0024] After capturing the features of the object using 3D camera 5 and 2D camera 6, the object can be divided into three sorting paths based on its features: normal conveying on the front side of conveyor table 1, and conveying on the two sliding platforms 11 on both sides. When the objects slide out from the sides, motor 7 can be started. Motor 7 drives the rotating frame 8 to rotate, which in turn moves the push-out frame 10 to the upper middle part of conveyor table 1. When the push-out frame 10 contacts the object, it can push the object to one side onto the sliding platform, thus sorting the object. After motor 7 drives the rotating frame 8 and the push-out frame 10 to reset, the push-out frame 10 will fit against the straightening plate 12, so that the push-out frame 10 can rotate and reset around the rotating axis 9, keeping parallel to the conveyor table, ensuring that it can fit against one side of the object when it is pushed out next time.
