Description

Technical Field

[0001] This invention belongs to the field of waste resource recycling technology, specifically a system for classifying and dismantling scrapped vehicles. Background Technology

[0002] Scrapped vehicles are those that have reached the national scrapping standard, or those that, although not reaching the national scrapping standard, have severely damaged engines or chassis and fail to meet the national motor vehicle operation safety technical conditions or the national motor vehicle pollutant emission standards after inspection. Scrapped vehicles contain a large amount of recyclable materials such as metals, plastics, and rubber, which are recycled through dismantling.

[0003] A Chinese patent with publication number CN110588845B discloses a scrapped car dismantling system. The system, in the order of processing, includes a vehicle power recovery device, a scrapped car parking device, a scrapped car processing platform, and a parts processing device. A tilting mechanism is located on one side of the scrapped car processing platform, which tilts the car's chassis upwards. The tilting mechanism includes a second motor, pulleys, and a hook. The hook is provided with towing power by the second motor. The pulleys are positioned so that the hook passes over the scrapped car from one side and hooks onto the other side. The use of the second motor, pulleys, and hook in the tilting mechanism facilitates the upward rotation of the scrapped car's chassis, greatly simplifying dismantling, reducing labor intensity, and improving production efficiency. A flattening mechanism raises the scrapped car to the top of the support frame, where it is compressed against the frame, reducing its footprint and facilitating transportation.

[0004] The aforementioned existing technologies achieve efficient dismantling of end-of-life vehicles, which include materials such as metal, plastic, and rubber, and these materials are generally recyclable. However, these technologies do not classify the dismantled materials, thus requiring further classification and recycling of various parts and materials. This not only increases the difficulty of subsequent resource reuse but may also affect the recycling value.

First, the scrapped vehicle enters the pre-processing module, where basic vehicle information is acquired through a vehicle information collection unit, the vehicle is cleaned through a vehicle cleaning unit, and components such as tires, batteries, and fuel tanks are removed through a dismantling unit. The pre-processed scrapped vehicle is then conveyed to an intelligent dismantling station via a conveying module. Next, the sorting and identification module identifies the vehicle parts and materials, transmitting the identification results to a controller.

The dismantling robot's dismantling process is programmed by a controller, which performs orderly dismantling according to vehicle model. During the dismantling of specific components, an infrared detection camera detects the specific material of the component and transmits the collected information to the controller. After dismantling, the component is placed on a first conveyor belt. While the first conveyor belt is transporting the component, the controller moves to a set position and activates a cylinder.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 As shown in the figure, the scrapped car sorting and dismantling system of the present invention includes a pretreatment module, a conveying module, a sorting and identification module, a dismantling module, a sorting and recycling module, and an environmental protection treatment module; The pre-processing module is used to collect vehicle information, clean the exterior, and perform preliminary dismantling of the scrapped vehicles; the conveying module is used to transport the pre-processed scrapped vehicles to the dismantling station; the classification and identification module is used to identify the type, material, and location information of the scrapped vehicle parts; the dismantling module is used to accurately dismantle the scrapped vehicle parts based on the classification and identification information; the classification and recycling module classifies and recycles the dismantled parts according to their materials; and the environmental protection treatment module treats the wastewater, waste gas, and waste residue generated during the dismantling process in a harmless manner.

[0023] The preprocessing module includes a vehicle information acquisition unit, a vehicle cleaning unit, and a disassembly processing unit. The vehicle information acquisition unit uses infrared radio frequency identification technology to acquire basic vehicle information. The disassembly processing unit is used to initially disassemble the tires, battery, and fuel tank.

[0024] The disassembly module includes a wrench robot, a cutting robot, and a hydraulic shear robot; the wrench robot is used to disassemble screws and nuts by controlling torque; the cutting robot is used to cut metal frames and body structural components; and the hydraulic shear robot is used to cut wire harnesses and sealing strips.

[0025] The sorting and recycling module includes a metal recycling unit, a plastic recycling unit, a rubber recycling unit, and a mixed material recycling unit.

[0026] The classification and dismantling system provided by this invention first involves scrapped vehicles entering a pre-processing module. Basic vehicle information is acquired through a vehicle information collection unit, and the vehicle is cleaned through a vehicle cleaning unit. Tires, batteries, fuel tanks, and other components are removed through a dismantling unit. The pre-processed scrapped vehicles are then transported to an intelligent dismantling station via a conveying module. Next, a classification and identification module identifies the vehicle parts and materials, transmitting the identification results to a controller. Following this, the dismantling module, based on the identification information, uses a wrench robot, a cutting robot, and a hydraulic shear robot to precisely dismantle the parts. The dismantled materials are then classified and placed into a classification and recycling module for recycling. Simultaneously, an environmental protection module treats the generated pollutants during the dismantling process, ensuring environmental safety.

[0027] When a vehicle enters the pre-processing area, a QR code scanner quickly reads the vehicle's chassis number, engine number, and other information, which is then uploaded to the controller. The controller automatically matches the preset preliminary disassembly process based on the collected information. The vehicle's exterior undergoes a comprehensive cleaning, after which professional operators remove components such as tires, batteries, and fuel tanks. The controller is configured with a computer, where control programs are set up for communication between various modules.

[0028] During disassembly, multiple infrared detection cameras 32 are installed above the disassembly station to perform a comprehensive scan of the vehicle's exterior and components, quickly identifying the outline, shape, and material characteristics of the components, providing a reliable basis for disassembly; the station is equipped with various types of disassembly robots 3, such as wrench robots, cutting robots, and hydraulic shear robots. Wrench robots are used to disassemble screws, nuts, and other connecting parts; cutting robots are used to cut metal frames and body structural parts; and hydraulic shear robots are used to cut wire harnesses, sealing strips, etc.

[0029] After disassembly, the parts need to be recycled. Conveyor belts are used to transport the metal, plastic, rubber and mixed material parts separately, and then process and reuse them.

[0030] Wastewater, waste gas, and waste residue generated during the dismantling process are treated to render them harmless. For cleaning wastewater and oily wastewater generated during dismantling, large particulate impurities are removed through sedimentation and filtration, followed by biochemical treatment to remove oil, heavy metal ions, and other harmful substances, ensuring they meet emission standards before discharge. For waste gas, activated carbon is used to efficiently adsorb organic matter, converting it into harmless carbon dioxide and water, ensuring the treated waste gas meets emission standards. Non-recyclable solid waste is collected separately; landfillable waste residue is disposed of through landfill, while combustible waste residue is incinerated for power generation, achieving harmless treatment of the waste residue.

[0031] like Figures 2 to 7 As shown, the disassembly module includes a disassembly robot 3. A conveying mechanism is provided on one side of the disassembly robot 3, and a sorting mechanism is provided on the other side. The sorting mechanism includes a first conveyor belt 4. Four second conveyor belts 41 are provided on one side of the first conveyor belt 4. The second conveyor belts 41 are evenly arranged and perpendicular to the first conveyor belt 4. Four side plates 42 are fixedly connected to the top of the first conveyor belt 4 away from the second conveyor belts 41. A cylinder 43 is fixedly connected to each side plate 42. A push plate 44 is fixedly connected to the output end of each cylinder 43. Two crossbars 45 are fixedly connected to the side wall of each push plate 44, and the crossbars 45 are slidably connected to the corresponding side plate 42. A second motor 33 is fixedly connected to the output end of the disassembly robot 3. The output shaft of the second motor 33 is rotatably connected to the disassembly robot 3 via bearings. A pneumatic gripper 31 is fixedly connected to the output shaft of the second motor 33. An infrared detection camera 32 is provided on one side of the pneumatic gripper 31 and is mounted on the output end of the disassembly robot 3.

[0032] The sorting mechanism provided by this invention, when in use, uses a dismantling robot 3 to dismantle scrapped vehicles. The dismantling process of the dismantling robot 3 is programmed by a controller, which dismantles the vehicles in an orderly manner according to their vehicle models. When dismantling specific parts, an infrared detection camera 32 detects the specific material of the part and transmits the collected information to the controller. After dismantling, the parts are placed on the first conveyor belt 4. When the first conveyor belt 4 transports the parts, the controller moves it to a set position and activates the cylinder 43. The output end of the cylinder 43 drives the push plate 44 to move, pushing the parts onto the corresponding second conveyor belt 41, thus classifying parts of different materials. The first and second conveyor belts 4 and 41 use stainless steel frames, and the surface of the conveyor belts is made of high-density polyethylene material, which improves the load-bearing capacity of the first and second conveyor belts 4 and 41 and prevents metal parts from scratching the conveyor belts. The dismantling robot 3 includes a wrench robot, a cutting robot, and a hydraulic shear robot.

[0033] like Figure 3 As shown, the conveying mechanism includes a conveying track 1 and a conveying trolley 2. The conveying trolley 2 moves on the conveying track 1, and a baffle 21 is installed on the top of the conveying trolley 2.

[0034] The conveying mechanism provided by this invention is used to transport scrapped cars to the corresponding work station. The conveying track 1 is made of high-strength aluminum alloy and is laid on the floor of the dismantling workshop. Multiple partitions are set on the conveying trolley 2 to reduce shaking during the dismantling process. A baffle 21 is set on its top to prevent dismantling debris from splashing out and affecting the transmission of the reciprocating screw 23.

[0035] like Figure 5 and Figure 6 As shown, two fixed plates 22 are fixedly connected to the side wall of the conveying trolley 2. A reciprocating screw 23 is rotatably connected between the two fixed plates 22 via bearings. A moving block 26 is threaded onto the reciprocating screw 23. A first motor 25 is fixedly connected to one of the fixed plates 22, and the output shaft of the first motor 25 is fixedly connected to one end of the reciprocating screw 23. Two guide rods 24 are fixedly connected between the two fixed plates 22, and the moving block 26 is slidably connected to the two guide rods 24. A fixing mechanism is provided on the moving block 26, and the fixing mechanism includes... The moving frame 27 is fixedly connected to the moving block 26. A pressure rod 271 is rotatably connected to the moving frame 27 via a rotating shaft. One end of the rotating shaft extends to the outside of the moving frame 27 and is fixedly connected to a gear 274. An electric push rod 272 is fixedly connected to the moving frame 27. A rack 273 is fixedly connected to the output end of the electric push rod 272. The rack 273 meshes with the gear 274. A limit rod 275 is fixedly connected to the side wall of the rack 273 near the moving frame 27. A limit groove is formed on the moving frame 27, and the limit rod 275 slides in the limit groove.

[0036] The fixing mechanism provided by this invention is used to fix scrapped vehicles. The dismantling robot 3 dismantles the scrapped vehicle at a predetermined position. During dismantling, the first motor 25 is activated, and its output shaft drives the reciprocating screw 23 to rotate. The reciprocating screw 23 then drives the moving block 26 to move, which in turn drives the moving frame 27 to move until it reaches the appropriate position. During this movement, the moving block 26 slides on the guide rod 24, which limits the moving block 26 to a horizontal position. The car moves in the vertical direction; then the electric push rod 272 is activated, and the output end of the electric push rod 272 drives the rack 273 to move, the rack 273 drives the gear 274 to rotate, the gear 274 drives the rotating shaft to rotate, and the rotating shaft drives the pressure rod 271 to rotate until the scrapped car is firmly pressed onto the conveying trolley 2, and then it is disassembled. During the movement of the rack 273, the rack 273 drives the limiting rod 275 to slide. The limiting rod 275 slides in the limiting groove and limits the rack 273 to move in the vertical direction.

[0037] Working principle: First, the scrapped vehicle enters the pre-processing module, where basic vehicle information is acquired through the vehicle information collection unit. The vehicle is then cleaned by the vehicle cleaning unit, and components such as tires, batteries, and fuel tanks are removed by the dismantling unit. After pre-processing, the scrapped vehicle is transported to the intelligent dismantling station via a conveying module. Next, a classification and identification module identifies the vehicle parts and materials, transmitting the identification results to the controller. Then, based on the identification information, the dismantling module, using wrench robots, cutting robots, and hydraulic shear robots, precisely dismantles the parts. The dismantled materials are then classified and placed into a recycling module for recycling. During the dismantling process, an environmental protection module simultaneously treats the generated pollutants to ensure environmental safety.

[0038] The dismantling robot 3 dismantles the scrapped car at a predetermined location. During dismantling, the first motor 25 is activated, and its output shaft drives the reciprocating screw 23 to rotate. The reciprocating screw 23 then moves the moving block 26, which in turn moves the moving frame 27 until it reaches the desired position. During this movement, the moving block 26 slides on the guide rod 24, which limits its horizontal movement. Then, the electric push is activated. The rod 272 drives the rack 273 to move through the output end of the electric push rod 272. The rack 273 drives the gear 274 to rotate, the gear 274 drives the rotating shaft to rotate, and the rotating shaft drives the pressure rod 271 to rotate until the scrapped car is firmly pressed onto the conveying trolley 2 for dismantling. During the movement of the rack 273, the rack 273 drives the limiting rod 275 to slide. The limiting rod 275 slides in the limiting groove and limits the rack 273 to move in the vertical direction.

[0039] The dismantling robot 3 dismantles the scrapped car. The dismantling process of the dismantling robot 3 is programmed by the controller, which dismantles the car in an orderly manner according to the car model. When dismantling a specific part, the infrared detection camera 32 detects the specific material of the part and transmits the collected information to the controller. After dismantling, the part is placed on the first conveyor belt 4. When the first conveyor belt 4 is transporting the part, the controller moves it to the set position and activates the cylinder 43. The output end of the cylinder 43 drives the push plate 44 to move, and the push plate 44 pushes the part onto the corresponding second conveyor belt 41, thus classifying the parts of different materials. The first conveyor belt 4 and the second conveyor belt 41 are made of stainless steel frame and the surface of the conveyor belt is made of high-density polyethylene material, which improves the load-bearing capacity of the first conveyor belt 4 and the second conveyor belt 41 and also prevents the metal parts from scratching the conveyor belt.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
