Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted energy system technology, specifically to a rapid identification sensor structure for a waste intelligent sorting system. Background Technology

[0002] Waste sorting generally refers to a series of activities involving the sorting, storage, disposal, and transportation of waste according to certain regulations or standards, thereby transforming it into public resources. The purpose of waste sorting is to increase the resource and economic value of waste, reduce the amount of waste to be processed and the use of processing equipment, lower processing costs, and reduce the consumption of land resources, thus having social, economic, and ecological benefits.

[0003] Chinese Patent Application No. 202220700014.4 provides an intelligent sorting trash can. Trash enters the trash can through a trash inlet on the flip-top lid. After entering the trash can, the trash is temporarily stored on a trash tray of a trash sorting mechanism. At this time, the sensor recognition unit and image recognition unit of the trash detection mechanism classify and detect the trash to determine the type of trash. This type of trash corresponds to one of the openings in the four-compartment recycling bin. Then, the main controller controls the trash tray to rotate until the drop-in port aligns with the opening in the four-compartment recycling bin corresponding to the type of trash. The main controller then controls the sorting unit to push the trash into the drop-in port, completing the intelligent sorting and storage of trash. The four-compartment recycling bins are arranged in a matrix structure in conjunction with the trash sorting mechanism for sorting and storing trash. The trash sorting mechanism has a simple structure and is easy to maintain. The entire trash can also has the advantages of small size, beautiful appearance, and simple operation. The above solution also has certain shortcomings. It only uses visual sensors for identification and classification, but does not take into account the situation where the shooting effect is not ideal in poor lighting conditions or backlighting.

[0026] A rectangular support sleeve 10 is mounted on the movable seat of the Z-axis lead screw conveyor 2, which is mounted on the movable seat of the Y-axis lead screw conveyor 1. The rectangular support sleeve 10 serves as the load-bearing structure for the sensor module, and through the Z-axis lead screw conveyor 2, it enables precise vertical displacement adjustment along the Z-axis, ensuring the sensor can adapt to the detection needs of waste at different heights.

[0027] The Z-axis lead screw conveyor 2 is further mounted on the movable seat of the Y-axis lead screw conveyor 1, enabling the entire sensor module to move horizontally along the Y-axis, forming a two-dimensional planar scanning capability that covers the waste sorting area on the conveyor belt.

[0028] A connecting lug 3 is welded to the upper part of the Y-axis lead screw conveyor 1, and the connecting lug 3 has a mounting hole. The connecting lug 3 is made of high-strength stainless steel and welded to the top of the Y-axis lead screw conveyor 1, providing a rigid connection interface with an external frame or conveyor belt system.

[0029] The mounting holes feature a standardized thread design, making them easy to match with waste sorting equipment of different specifications, ensuring the versatility and convenience of system installation.

The optical lens assembly housing 6 houses a conical lens 14, a convex lens 15, a beam splitter 16, and an achromatic focusing objective lens 17. The conical lens 14 is used to widen the field of view of the incident light to ensure wide coverage of the debris on the conveyor belt, while the convex lens 15 performs preliminary focusing of the light to reduce optical distortion.

[0031] The beam splitter 16 divides the light into visible light and infrared light channels, which are used for color recognition and material analysis, respectively.

A heat-conducting rod 95 is welded through and welded to the second aluminum radiator 94. A metal core 18 is provided inside the insulation shell 12, and one end of the metal core 18 has an insertion hole. The second aluminum radiator 94 transfers cold energy to the metal core 18 through the heat-conducting rod 95, so that the temperature inside the insulation shell 12 is evenly distributed.

[0038] In the rapid identification sensor structure of the intelligent waste sorting system in this embodiment, the optical sensor 4 can be a high-precision CCD image sensor, such as Sony's ILX511B, which has high resolution and good photosensitivity and can accurately acquire optical signals. The infrared sensor 5 can be Hyman's HIS-071B, which has high sensitivity to the detection of infrared features of objects and can greatly improve the identification accuracy when working in conjunction with the optical sensor 4.

[0039] For the controller, the edge AI MCU "CCR4001S" based on the RISC-V architecture developed by Guoxin Technology can be selected. It is suitable for industrial application scenarios such as sorting robots, and can efficiently process the data collected by the sensor to achieve precise control of the entire sensor structure and related actuators.

[0040] In summary, the rapid identification sensor structure of the intelligent waste sorting system provided in this embodiment has the following advantages: the optical sensor 4 serves as the core optical signal acquisition unit, and achieves wide field of view coverage through the optical lens assembly housing 6 connected at the bottom.

[0041] Infrared sensor 5 assists in detecting the infrared features of objects, and works in conjunction with optical sensor 4 to improve recognition accuracy.

[0042] Optical lens assembly 6: Composed of a conical lens 14, a convex lens 15, a beam splitter 16 and an achromatic focusing objective lens 17, it completes light focusing, beam splitting and chromatic aberration correction to ensure image clarity, and is coaxially set with the light of the optical sensor 4 to prevent changes in the field of view position. The observation tube 7 provides a stable optical channel to reduce ambient light interference.

[0043] The turntable optical device 8 is driven by a stepper motor 13. It achieves pulsed light modulation by periodically switching the light-transmitting parts 83 of the first light-blocking block 81 and the second light-blocking block 82 through the light-blocking turntable 86.

[0044] The guide transparent block 85 transmits the modulated light to the photosensitive element 84, which converts it into an electrical signal.

[0045] Stepper motor 13: Precisely controls the rotation speed of the turntable, adapts to the scanning frequency requirements of different types of waste, and can determine whether the light direction is backlit by two light-blocking blocks, thus providing conditions for back-end correction.

[0046] The cooling element 93 actively cools through the Peltier effect to maintain the sensor's operating temperature. The first aluminum heat sink 92 and fan 91 are the hot end of the cooling element. The second aluminum heat sink 94 transfers the cold energy to the metal core 18 through the heat-conducting rod 95 to balance the internal temperature of the insulation housing 12. One end of the metal core 18 is connected to the interior of the optical lens assembly housing 6.
