Description

Technical Field

[0001] This utility model relates to the field of waste sorting technology, and in particular to an intelligent waste sorting device. Background Technology

[0002] The proper sorting and disposal of household waste is directly related to the human living environment. With the continuous improvement of people's living standards, the technical requirements for household waste sorting and processing are also increasing. Residents' daily waste is called household garbage, which generally includes four categories: kitchen waste, recyclable waste, hazardous waste, and other waste. Traditional waste sorting methods mainly rely on manual sorting at waste stations, where sorters sift through the chaotic household waste and place the sorted waste into different types of bins. This manual sorting method suffers from problems such as low efficiency and insufficient accuracy.

[0003] Intelligent waste sorting devices are gradually becoming an important tool for improving waste disposal efficiency. Their emergence not only improves the accuracy of waste sorting but also automates operations, reducing manual intervention and increasing sorting efficiency. However, existing intelligent waste sorting devices have some drawbacks. This is because waste sorting typically uses a telescopic robotic arm to grab and classify waste, requiring knowledge of the waste's location coordinates. Therefore, a camera needs to be mounted in the center of the top surface of the waste bin. However, this obstructs waste disposal, and liquids and oils, such as kitchen waste and other waste, can easily splash onto or touch the camera, causing it to become dirty and affecting its accurate identification. Furthermore, beverage bottles and cardboard boxes in recyclable waste take up considerable space, resulting in less recyclable waste in the recyclable waste bins and reducing recycling efficiency. Utility Model Content

[0004] To address the technical problems of existing technologies, such as the easy splashing or contact of household waste containing liquids and oil with the camera, resulting in the camera becoming dirty and affecting its accurate identification of waste, and the large space occupied by beverage bottles and cardboard boxes in recyclable waste, which reduces the recycling efficiency of recyclable waste, this utility model provides the following technical solution.

[0005] This utility model discloses an intelligent waste sorting device, comprising a housing with an upper cover plate at the top and a fixed frame located inside the housing cavity. The upper cover plate has a waste disposal port. The upper part of the fixed frame is connected to two oppositely arranged Y-axis synchronous belt modules, and the two Y-axis synchronous belt modules are connected to an X-axis synchronous belt module. The bottom of the upper cover plate is fixedly provided with laser matrix sensors for monitoring waste disposal located on both sides below the waste disposal port. The X-axis synchronous belt module is connected to a movable slide. The movable slide is fixedly connected to a robotic arm and a camera. A camera baffle is fixedly connected to one side of the fixed frame. A waste holding platform controlled by a servo motor assembly is provided directly below the waste disposal port. The lower part of the fixed frame is provided with several waste bins for the waste holding platform to dispose of waste.

[0006] As a further technical solution, the waste temporary storage platform is provided with a baffle plate around it, and the baffle plate is located directly above the waste bin.

[0007] As a further technical solution, the bottom of the fixed frame is provided with a support frame and a fixing block located on the upper part of the support frame, and the upper part of the fixing block is connected to the servo assembly.

[0008] As a further technical solution, the trash can includes an array of recyclable trash cans, hazardous waste trash cans, food waste trash cans and other trash cans, with a compression component connected to the fixed frame below the hazardous waste trash can, and the compression component extending into the recyclable trash can.

[0009] As a further technical solution, the compression assembly includes an electric push rod fixedly connected to the fixed frame and a compression moving plate that can extend into the recyclable waste bin and is connected to the output end of the electric push rod. A compression fixing plate is provided on the other side of the recyclable waste bin, which is opposite to the compression moving plate.

[0010] As a further technical solution, the outer wall of the shell is provided with several trash can opening and closing plates.

[0011] As a further technical solution, the inside of the trash can is equipped with an infrared detector for monitoring whether the trash can is full.

[0012] As a further technical solution, the upper cover plate is connected to an information display screen.

[0013] The beneficial effects of this invention are as follows: The camera and robotic arm are mounted together on a movable slide. The camera can move like the robotic arm. Before detecting waste, the camera moves with the slide to above a camera baffle on one side of the fixed frame. At this point, the camera will not obstruct the waste disposal and will not be splashed or touched by liquids, oils, or other household waste, ensuring accurate waste classification. When waste is disposed of, the laser matrix sensor transmits a signal to the control system. The Y-axis and X-axis synchronous belt modules then drive the movable slide to move, positioning the camera above the waste storage platform for identification. Based on the detected waste type and quantity, the robotic arm or servo motor assembly can be driven to sort the waste into the corresponding bins, resulting in high waste sorting efficiency. Simultaneously, a compression component is located below the hazardous waste bin. This compression component can compress cardboard boxes, beverage bottles, and other waste in the recyclable waste bin, reducing space occupation and improving the utilization rate of the recyclable waste bin.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] In the description of this utility model, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] like Figure 1 and Figure 2 As shown, this utility model discloses an intelligent waste sorting device, comprising a housing 1 and a fixed frame 2 located within the cavity of the housing 1. The housing 1 has an upper cover plate 101 at its upper end, and a waste disposal port 102 is located in the middle of the upper cover plate 101, through which household waste can be disposed. The fixed frame 2 is composed of multiple columns. Y-axis synchronous belt modules 3 are arranged in parallel on opposite sides of the upper part of the fixed frame 2. The two Y-axis synchronous belt modules 3 are connected to an X-axis synchronous belt module 4, which is connected to a movable slide 5. Thus, the Y-axis synchronous belt modules 3 and X-axis synchronous belt modules 4 can drive the movable slide 5 to move in multiple directions on a two-dimensional plane. The Y-axis synchronous belt modules 3 and X-axis synchronous belt modules 4 adopt existing structures; therefore, the stepper motors, control systems, and specific structures used in them will not be described in detail.

[0024] like Figure 3As shown, in a preferred embodiment, a laser matrix sensor 11 is fixedly installed at the bottom of the upper cover plate 101. The laser matrix sensor 11 is located on both sides below the garbage disposal port 102 and is used to monitor whether garbage is being disposed of. When the laser matrix sensor 11 is installed at the bottom of the upper cover plate 101, it does not affect the movement of the movable slide 5 and will not touch the movable slide 5. The movable slide 5 is fixedly connected to a robotic arm 12 and a camera 13, which can move in multiple directions with the movable slide 5. The camera 13 is used to identify the type of garbage, and after identification, the robotic arm 12 sorts the garbage. The robotic arm 12 is controlled by a servo motor and is responsible for grabbing and disposing of garbage. After grabbing garbage, the movable slide 5 moves above the corresponding garbage bin. The robotic arm 12 automatically opens and closes when disposing of garbage to ensure that each piece of garbage can be accurately placed in the correct garbage bin.

[0025] A battery and main control board are located on one side of the fixed frame 2, used to control the robotic arm 12, camera 13, Y-axis synchronous belt module 3, and X-axis synchronous belt module 4. The battery and main control board are positioned to avoid collisions with garbage. A camera baffle 14 is fixedly connected to one side of the fixed frame 2. The camera baffle 14 is a plate structure, and its position does not affect the movement of the moving slide 5. When no garbage is being disposed of, the Y-axis synchronous belt module 3 and X-axis synchronous belt module 4 control the moving slide 5 to move the camera 13 above the camera baffle 14. At this time, the camera 14 will not obstruct the disposal of garbage and will not be splashed or touched by liquid oil or other household waste, ensuring accurate identification of garbage by the camera 13.

[0026] In a preferred embodiment, the upper cover 101 is connected to an information display screen 10, which is electrically connected to the main control board. The information display screen 10 displays waste information in real time. After each type of waste is sorted, the sorted waste information is displayed on the screen. Simultaneously, the information display screen 10 can also display the sorting quantity of each type of waste and a task completion prompt. When multiple waste bins inside the housing 1 reach full capacity, the information display screen 10 automatically triggers a full-load prompt, reminding the user to empty them promptly.

[0027] like Figure 4 and Figure 5As shown, in a preferred embodiment, a waste disposal platform 7 controlled by a servo motor assembly 6 is located directly below the waste disposal port 102. Several waste bins for the waste disposal platform 7 to dispose of waste are located at the lower part of the fixed frame 2. Supplementary lights connected to the fixed frame 2 are located around the perimeter of the waste disposal platform 7 at an angle above it, enabling the camera 13 to effectively identify the waste on the upper part of the waste disposal platform 7 in dark environments. Specifically, the bottom of the fixed frame 2 has two intersecting support frames 201 and a fixing block 202 located on the upper part of the support frames 201. The upper part of the fixing block 202 is connected to the servo motor assembly 6. The servo motor assembly 6 uses a combination of four servos, which respectively dispose of the waste disposal platform 7 to the waste bins in four different directions. This servo motor combination structure, which allows for direct disposition without horizontal rotation, can significantly reduce waste disposal time.

[0028] Meanwhile, the upper surface of the garbage disposal platform 7 is made of shock-absorbing material, which can prevent garbage from bouncing away and prevent garbage thrown from the garbage disposal port 102 from elastically colliding with the garbage disposal platform 7. The garbage disposal platform 7 is equipped with four baffles 701 around its perimeter, with each baffle 701 located directly above a different garbage bin. The servo motor assembly 6 can control the garbage disposal platform 7 to dump garbage into the garbage bins in different directions.

[0029] like Figure 6 As shown, in a preferred embodiment, the trash cans include an array of recyclable waste bins 15, hazardous waste bins 16, kitchen waste bins 17, and other waste bins 18. Each trash can has an infrared detector 9 on its inner side for monitoring whether it is full. At this time, four trash can opening plates 103 are connected to the outer wall of the housing 1 via hinges. An iron sheet is fixedly connected to one side of each trash can opening plate 103, and a magnet is fixedly connected to the fixing frame 2. Thus, the trash can opening plate 103 can be magnetically fixed to the fixing frame 2. When a trash can is full, the trash can opening plate 103 can be opened to remove the trash.

[0030] In a preferred embodiment, a compression assembly 8 connected to a fixed frame 2 is provided below the hazardous waste bin 16. The compression assembly 8 extends into the recyclable waste bin 15 to compress the recyclable waste. Specifically, the compression assembly 8 includes an electric push rod 801 fixedly connected to the fixed frame 2 and a compression moving plate 802 connected to the output end of the electric push rod 801. The compression moving plate 802 can extend into the recyclable waste bin 15, and a compression fixing plate 803 is provided on the other side of the recyclable waste bin 15, which is opposite to the compression moving plate 802.

[0031] In use, initially, the camera 13 moves with the sliding table 5 to above the camera baffle 14. When the laser matrix sensor 11 detects garbage being disposed of at the garbage disposal port 102, the sliding table 5 moves the camera 13 and the robotic arm 12 to above the garbage collection platform 7 to identify the garbage. If there are multiple pieces of garbage on the garbage collection platform 7, the sliding table 5 will be moved to a designated position above the garbage based on the garbage location information identified by the camera 13. The robotic arm 12 will then retract and grab the garbage and dispose of it in the corresponding garbage bin. After disposal, the camera 13 returns to directly above the garbage collection platform 7. The waste is first identified, and then sorted using the moving slide 5 and the robotic arm 12. This process is repeated until there is only one piece of waste on the waste storage platform 7. After the camera 13 identifies the waste, the servo motor assembly 6 drives the waste storage platform 7 to tilt and dump the waste into the corresponding waste bin. At the same time, the information display screen 10 displays the waste information in real time. If the sorted waste is recyclable, the compression assembly 8 will compress the waste once. Each of the four waste bins is equipped with an infrared detector 9. When the amount of waste in a waste bin exceeds 75% of its total capacity, the information display screen 10 will show that the waste bin is full.

[0032] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
