DETAILED DESCRIPTION

[0030] In this embodiment, an intelligent classification trash can is provided, including a trash can main frame 1, a plurality of classification boxes 21 installed in the trash can main frame 1, a garbage storage module installed on the trash can main frame 1 and located above the classification box 21, an identification module installed on the trash can main frame 1 for detecting garbage in the garbage storage module, a mechanical picking and placing module installed on the trash can main frame 1 and located above the garbage storage module, and a visual control module 24 for controlling the garbage storage module and the mechanical picking and placing module based on the identification module.

[0031] The working principle of this embodiment is as follows: first, the garbage is placed in the garbage temporary storage module, and then the identification module is used to collect garbage information, and then the visual control module 24 is used to control the mechanical pick-up and placement module to grab the garbage, and the mechanical pick-up and placement module is adjusted to above the classification box 21 corresponding to the garbage type, and then the support top plate 19 and the baffle 16 (the classification box 21 corresponding to the garbage type) on the garbage temporary storage module are controlled to separate, and the garbage grabbed by the mechanical pick-up and placement module is controlled to be released, and the gap is opened along the support top plate 19 and the baffle 16 to enter the corresponding classification box 21, thereby completing precise placement.

[0032] refer to Figure 1 The trash can main frame 1 includes four columns and a top crossbeam 38 connecting the columns; a fixed cross plate 20 is installed between the middle parts of the columns of the trash can main frame 1; a fixed top plate 37 for installing the visual control module 24 is installed on the top of the trash can main frame 1; an identification module is also installed on the fixed top plate 37, and the identification module includes at least one camera installed on the fixed top plate 37.

[0033] The visual control module 24 adopts a technical solution combining Python, PyQt5 and YOLOv8-seg, and is mainly responsible for image processing, garbage recognition, and user interaction. It is also compatible with Arduino and the intelligent voice recognition module based on RISC-V connected to DeepseekR1. Arduino controls the robotic arm to perform various actions; and uses a camera installed on the fixed top plate 37 to collect real-time images of garbage, clearly capturing the appearance characteristics of the garbage, including color, shape, texture and other information, and preprocessing the collected original images. The preprocessing operations include grayscale, filtering, noise reduction, contrast enhancement, etc. The color image is converted into a grayscale image through grayscale processing to reduce the amount of data and highlight the image quality. The brightness information of the image; the high-frequency noise in the image is removed by a filtering algorithm to make the image clearer, and the features of the garbage are extracted from the preprocessed image. These features can be color features, such as RGB values, HSV values, etc.; shape features, such as area, perimeter, aspect ratio, circularity, etc.; texture features, such as roughness, directionality, etc. By extracting and analyzing these features, different types of garbage can be distinguished, and the extracted features are compared and matched with a pre-established garbage category model or database. Machine learning or deep learning algorithms are used to classify and identify the garbage. According to the results of the classification and identification, the visual control module 24 sends a control signal to the sorting actuator to drive the corresponding mechanical device to sort the garbage, thereby realizing the separation of different types of garbage.

[0034] In this embodiment, the garbage temporary storage module includes a split storage tank bottom plate and four split storage tank side walls that cooperate with the split storage tank bottom plate to form a trough-shaped structure.

[0035] refer to Figure 1 and Figure 5 The split tank floor features a support top plate 19, whose tilt angle is adjustable via a platform 18. A mounting rail 17 is mounted on the fixed horizontal plate 20, directly below the support top plate 19. The platform 18 is mounted on the mounting rail 17. In practice, single-waste dumping utilizes a platform 18 with two degrees of freedom, providing up to four directions to meet the classification requirements of four major waste categories. The platform 18 is connected to the support top plate 19 platform, forming a temporary storage platform for the waste, and ultimately enables the platform 18 to drive the support top plate 19 to dump the waste.

[0036] The side wall of the split storage tank is a baffle 16 that is rotatably mounted on the main frame 1 of the trash can and spliced ​​with the supporting top plate 19; the lower end of the baffle 16 contacts the edge of the supporting top plate 19, and the upper end of the baffle 16 is hingedly mounted on two columns of the main frame 1 of the trash can, and a rotating servo 15 for adjusting the gap between the baffle 16 and the supporting top plate 19 is also installed on the main frame 1 of the trash can; in this embodiment, four rotating servos 15 are respectively fixedly connected to the inner sides of the four trash can main frames 1, and the drive output ends of the four rotating servos 15 are fixedly connected to the baffle 16 to prevent the garbage from bouncing into the incorrect trash can when throwing garbage, thereby ensuring that the garbage is correctly placed.

The two ends of the transmission shaft I7 are installed on the columns of the trash can main frame 1 through bearing seats, and the two ends of the transmission shaft II7a are installed on other columns of the trash can main frame 1 through bearing seats. The transmission shaft I7 is arranged vertically to the transmission shaft II7a.

[0042] When in use, the active pulley 13 on the driving shaft of the first drive motor 6 is connected to the transmission pulley Ⅰ8 on the transmission shaft Ⅰ7 through the transmission belt Ⅰ5, and the two parallel transmission shafts Ⅰ7 are also driven to rotate synchronously through the synchronous belt Ⅰ12. At the same time, the fixed connection between the synchronous belt Ⅰ12 and the connecting slider Ⅰ22 is used to drive the two connecting sliders Ⅰ22 to slide on the transmission shaft Ⅱ7a respectively, and then drive the Y-direction slide bar 39 connecting the two connecting sliders Ⅰ22 to slide axially along the transmission shaft Ⅱ7a, thereby driving the movable frame 23 on the pick-and-place actuator to slide axially along the transmission shaft Ⅱ7a.

[0043] Similarly, the active pulley 13 on the driving shaft of the second drive motor 14 is connected to the drive pulley Ⅱ11 on the transmission shaft Ⅱ7a through the transmission belt Ⅱ5a, and the two parallel transmission shafts Ⅱ7a are also synchronously driven to rotate through the synchronous belt Ⅱ12a. At the same time, the two connecting sliders Ⅱ22a are driven to slide on the transmission shaft Ⅰ7 respectively by the fixed connection between the synchronous belt Ⅱ12a and the connecting slider Ⅱ22a, thereby driving the X-axis slide bar 40 connecting the two connecting sliders Ⅱ22a to slide axially along the transmission shaft Ⅰ7, thereby driving the movable frame 23 on the pick and place actuator to slide axially along the transmission shaft Ⅰ7. In specific implementation, the first drive motor 6 and the second drive motor 14 are simultaneously controlled by the visual control module 24, so as to achieve precise adjustment of the grasping position of the pick and place actuator.

[0044] refer to Figure 2In this embodiment, the pick-and-place actuator includes a mobile frame 23 adapted to be mounted on the X-axis slide bar 40 and the Y-axis slide bar 39, and a mobile frame 23 installed below the mobile frame 23; a first connecting frame 27 is fixedly connected to the bottom end of the mobile frame 23, a scissor-type servo 25 is fixedly mounted on one side of the first connecting frame 27, two first meshing arms 29 are symmetrically meshed and connected inside the first connecting frame 27, a connecting slot 28 is provided at the bottom end of the first meshing arm 29, a second meshing arm 32 is rotatably connected inside the connecting slot 28, and a second connecting frame 30 is rotatably connected to the outside of the second meshing arm 32, a rotating servo 31 is fixedly mounted on the top end of one side of the second connecting frame 30, a third connecting frame 36 is fixedly connected to the bottom end of the output shaft of the rotating servo 31, a gripper servo 34 is fixedly mounted on one side of the third connecting frame 36, and a third meshing arm 35 is meshed and connected on the other side of the third connecting frame 36 The end of the third meshing arm 35 is rotatably connected to the clamping mechanical claw 33, and the clamping mechanical claw 33 is internally connected to the guide arm 26. The end of the guide arm 26 away from the clamping mechanical claw 33 is rotatably connected to the side of the third connecting frame 36. The scissor-type servo 25 controls the angle change of the first meshing arm 29 to realize the extension and contraction of the first meshing arm 29. The visual control module 24 will intelligently detect the size of the garbage, and thus feedback different position information to the scissor-type servo 25. After reaching the set position, it stops and waits for the rotary servo 31 and the clamping claw servo 34 to clamp. After receiving the sent angle signal, the rotary servo 31 will move the clamping mechanical claw 33 to the angle corresponding to the garbage, so that the clamping mechanical claw 33 can perform accurate clamping. The clamping claw servo 34 is a bus servo. When it detects that the garbage has been clamped, the visual control module 24 will operate the clamping claw servo 34 to clamp ten degrees to ensure that the object is clamped.
