Description

Technical Field

[0001] The invention relates to the technical field of scrapped car processing, and in particular to a scrapped car disassembly production line and a disassembly process. Background Art

[0002] As people's living standards improve, the demand for and ownership of cars has increased rapidly. Today, cars have already entered ordinary people's homes, and some families even own more than one car. At the same time, the number of scrapped cars has also increased sharply, and the resulting environmental problems are becoming increasingly serious. Among them, the recycling of scrapped cars is a big problem. The reuse, remanufacturing and recycling of scrapped car parts and materials are crucial to protecting the environment and saving resources.

[0003] At present, the dismantling of scrapped cars is still in the violent dismantling period. The dismantling bases of scrapped cars are often transformed from the waste recycling enterprises in the past. The business model of the traditional car dismantling industry is: car collection - destructive dismantling - raw material sales. Its profits come from the meager income generated by selling raw materials, and the recycling rate of parts is not high. Moreover, under the traditional operation mode, there will be a large amount of solid waste left, oil and liquid seeping into the soil, and gas cutting polluting the air. In terms of production efficiency, traditional operations are relatively extensive.

[0004] Scrapped car recycling manufacturers will dismantle scrapped cars. Most companies use manual dismantling and manual gas cutting. The dismantling equipment has a low degree of integration and cannot achieve automated operation. The engine, gearbox, rear axle, steering gear and other important parts of the car must be completely destroyed according to regulations. For other parts of the car, scrap recycling manufacturers basically dismantle them and sell them as scrap metal. Due to the complex structure of the car, the dismantling of scrapped cars cannot be done accurately at present. Various iron, alloy, plastic, fiber, and glass fragments are mixed together. In the end, they can only be flattened and cut into small pieces for crushing and sorting, resulting in a low recycling rate.

[0005] The overall technical level of my country's scrap car recycling companies is backward, the process of dismantling cars is unclear and the dismantling methods are extensive. At the same time, during the dismantling process, due to the lack of standardized dismantling procedures, most of the dismantled car parts are not recycled. After the car body is crushed, a large amount of solid waste is generated, which also causes great harm to the environment. Summary of the invention

The methods used in the following examples are conventional methods unless otherwise specified.

[0050] [Example]

[0051] In this embodiment, the scrapped car dismantling production line consists of front and rear windshield dismantling station I, door dismantling station II, door dismantling robot, floor drag chain conveying line 8, interior offline dismantling station III, chassis offline dismantling station IV, chassis tipping device 10, plate chain conveyor 11 and AGV transport trolley 2.

[0052] Figure 1 The figure shows the overall arrangement of the scrapped car dismantling production line in this embodiment. The scrapped car 1, which has been pre-treated by oil extraction and liquid drainage, is transported to the front and rear windshield dismantling station I by an unmanned electric forklift. The front and rear windshields are completely dismantled manually, and the manually operated manipulator 12 places the dismantled front and rear windshields on the AGV transport trolley 2 and transports them to the storage area. The dismantled front and rear windshields can be reused to avoid the formation of solid waste.

[0053] There is a steel structure frame 6 made of channel steel and rectangular square tube in front of the front and rear windshield disassembly station I, the door disassembly station II and the ground drag chain conveyor line 8. A manually operated manipulator 12 is fixed on the steel structure frame 6 near the front and rear windshield disassembly station I to suck the disassembled front and rear windshields and then place them on the AGV transport trolley 2.

[0054] A track 7 is installed longitudinally in the middle of the steel structure frame, and a mobile manipulator 3 is arranged on the track 7. The upper roller of the mobile manipulator 3 moves freely forward and backward along the track under the control of the motor. A mechanical gripper is arranged at the bottom of the mobile manipulator 3, and the mechanical gripper can move up and down and open and close. The end of the mechanical gripper is inlaid with wear-resistant polyurethane material to prevent the scrapped car 1 from being scratched.

[0055] After the front and rear windshields are disassembled, the mobile manipulator 3 moves to the top of the scrapped car 1 in the front and rear windshields disassembly station Ⅰ. The mechanical gripper moves down and opens, grabs the scrapped car 1 and moves it to the door disassembly station Ⅱ for fully automatic disassembly of the left and right doors. Two groups of car disassembly robots are arranged on both sides of the scrapped car 1. In the default state, the doors of the scrapped car 1 are in a half-closed state. Through visual recognition technology, the suction cup robot 4 uses a suction cup to suck the door on the corresponding side and slowly pulls it open, and the hydraulic shear robot 5 uses a hydraulic shear to cut the hinges and hinges at the connection between the door and the body. After the door is separated from the body, the suction cup robot 4 uses a suction cup to place it on the AGV transport trolley 2 and transport it to the fine disassembly area.

[0056] The mobile manipulator 3 picks up the scrapped car 1 with the door removed and transports it to the ground drag chain conveyor line 8, and places it on the trolley. The scrapped car 1 circulates in the ground drag chain conveyor line 7. When it runs to the vicinity of the interior offline disassembly station III, it is removed from the ground drag chain conveyor line 8 by the crane on the steel structure support 9 for offline manual disassembly of the interior. There are multiple interior offline disassembly stations III, and the production rhythm is determined according to the actual production situation, and the work content of each interior offline disassembly station III is determined. The number of stations can be increased or decreased according to the actual production situation. The automobile interior parts that have been disassembled offline are placed on the AGV transport cart 2 and transported to the fine disassembly area and storage area.

[0057] The scrapped car 1 with the interior parts disassembled is placed back on the trolley of the ground-to-ground drag chain conveying line 8 for circulation.

[0058] The ground drag chain conveyor line 8 adopts existing products, which are composed of a drive system, a traction system, a trolley and a track. The scrapped car is placed on the trolley by the mobile manipulator 3. The trolley is dragged and moved cyclically on the drag chain track by the chain of the traction system. The drag chain track is a circular track composed of two parallel tracks and two arc-shaped connecting tracks.

[0059] The interior offline disassembly station III is surrounded by and on top of a steel structure support 9 made of channel steel and rectangular square tubes. A mobile small single-beam crane is provided on the top of the steel structure support 9 to remove the scrapped car 1 from the trolley of the ground drag chain conveyor line 8. Hydraulic shears, electric wrenches and other disassembly tools are hung on the frames around the steel structure support 9, and the operators use the tools to disassemble the scrapped car 1.

[0060] The scrapped car 1 with its interior disassembled is hoisted from the trolley of the floor drag chain conveying line 8 by the crane of the interior offline disassembly station III and placed in the chassis disassembly station III. After the scrapped car 1 is turned 180 degrees by the chassis tipping device 10, the operator manually disassembles the parts on the chassis with hydraulic shears. The disassembled car chassis parts are placed on the AGV transport trolley 2 and transported to the fine disassembly area and storage area.

[0061] The surrounding and upper part of chassis disassembly station IV are steel structure brackets 9 made of channel steel and rectangular square tubes. A mobile small single-beam crane is arranged on the top of the steel structure bracket 9 to remove the scrapped car 1 from the trolley of the ground drag chain conveying line 8.

[0062] The chassis tilting device 10 is composed of a frame 101, a pit 102, a base 103, a tilting assembly 104 and a pressing assembly 105. The frame 101 is a rectangular parallelepiped frame welded by profiles, and the base 103 is a flat rectangular parallelepiped frame welded by profiles.

[0063] The chassis tipping device 10 turns the scrapped car 1 whose chassis parts have been disassembled back to the original horizontal position, and uses the crane of the chassis disassembly station IV to place the scrapped car 1 whose chassis has been disassembled on the plate chain conveyor 11. The plate chain conveyor 11 conveys the frame of the completely disassembled scrapped car 1 to the crushing area.

[0064] The plate chain conveyor 11 adopts existing equipment, which is composed of a driving device, a frame, a chain, a support shaft and a metal plate. The driving device drives the chain to rotate, and the chain drives the support shaft and the metal plate to move back and forth. The effective width of the chain plate is about 3 meters, the conveying speed is 1-10 meters / minute, and the maximum weight of the conveyed items is 800 kg / square meter.

[0065] Finally, the car body dismantling machine is used to cut the frame into small pieces, which are then crushed and sorted by a crusher to form high-quality scrap steel.

[0066] The supports at each disassembly station are equipped with lighting and ventilation facilities.

[0067] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

A scrapped car dismantling process based on a scrapped car dismantling production line according to claim 1, characterized in that: The steps include: 1) The scrapped cars that have been pre-treated by oil extraction and liquid drainage are transported to the front and rear windshield disassembly station by unmanned electric forklifts. The operators manually remove the front and rear windshields completely, and manually operate the manipulator to place the disassembled front and rear windshields on the AGV transport trolley and transport them to the storage area; 2) After the front and rear windshield glass is disassembled, the mobile robot moves to the front and rear windshield glass disassembly station, and uses the mechanical gripper to grab the scrapped car and move it to the door disassembly station; 3) At the door disassembly station, the car disassembly robot disassembles the doors on both sides of the scrapped car; by default, the doors of the scrapped car are in a half-closed state; through visual recognition technology, the suction cup robot uses a suction cup to suck the door and slowly pulls it open, and the hydraulic shear robot uses a hydraulic shear to cut the hinges and hinges at the connection between the door and the car body; after the door is separated from the car body, the suction cup robot uses a suction cup to place the door on the AGV transport cart and transport it to the fine disassembly area; 4) The mobile manipulator picks up the scrapped car with the door removed and places it on the trolley of the floor drag chain conveyor line; when the scrapped car moves to the interior offline disassembly station, it is removed from the floor drag chain conveyor line by a crane, and the operator manually disassembles the interior of the scrapped car using disassembly tools; the interior parts disassembled offline are placed on the AGV transport trolley and transported to the fine disassembly area and storage area; 5) After the scrapped cars have been dismantled of their interior parts, they are placed back on the trolley of the floor drag chain conveyor line and circulate on the floor drag chain conveyor line. When they reach the chassis dismantling station, the crane places the scrapped cars on the chassis tipping device. After the chassis tipping device flips the scrapped cars 180 degrees, the operators use hydraulic shears to manually dismantle the parts on the chassis. The dismantled car chassis parts are placed on the AGV transport trolley and transported to the fine dismantling area and storage area. 6) The chassis tipping device turns the scrapped car with disassembled chassis parts 180 degrees back to its original horizontal position, and the scrapped car is placed on the plate chain conveyor by a crane. The plate chain conveyor transports the frame of the scrapped car after all the disassembly work is completed to the crushing area; in the crushing area, the body dismantling machine is used to cut the frame into small pieces, and then the crusher is used for crushing and sorting to form scrap steel.
