Embodiment 1

[0055] This embodiment provides a method for automatically disassembling the scrapped and recycled power battery pack of a new energy vehicle, such as figure 1 As shown, the method includes:

[0056] S1. Lift the new energy vehicle and clean the chassis.

[0057] When the power battery pack reaches the scrapping standard or the new energy vehicle reaches the scrapping standard, the power battery pack needs to be disassembled. During the use of new energy vehicles, the chassis of the car will be covered with dust, water, etc. Therefore, it is necessary to clean the chassis of the car when it is automatically disassembled. Manual disassembly does not require high chassis cleanliness, and generally does not require chassis cleaning.

[0058] In this embodiment, firstly, the car is lifted to the top of the cleaning equipment. Then, wash the chassis of the car through a high-pressure water gun, and the pressure of the high-pressure water gun is 10Mpa-25Mpa. Finally, the car cha...

Embodiment 2

[0101] Such as image 3 As shown, this embodiment provides an automatic disassembly system for scrapping and recycling power battery packs of new energy vehicles, including:

[0102] Lifting and cleaning module 110, used for lifting new energy vehicles and cleaning the chassis;

[0103] The data acquisition module 120 is used to read the structural parameters of the power battery pack stored in the two-dimensional code of the chassis;

[0104] The image acquisition module 130 is used to acquire the image of the automobile chassis, and sends the acquired image to the image processing module;

[0105] The image processing module 140 is used to process the image of the automobile chassis, and recognize the screws in the image;

[0106] A calculation module 150, configured to calculate a virtual distance and a virtual included angle according to the screw information identified by the image processing module;

[0107] Comparison module 160, used to compare virtual parameters an...

Abstract

The present invention provides a method for automatically disassembling the scrapped and recycled power battery pack of a new energy vehicle. By lifting the new energy vehicle, cleaning the chassis, obtaining the structural parameters of the power battery pack, collecting an image of the chassis of the vehicle, identifying the screws in the image, and calculating The virtual parameters of two adjacent screws are compared with the actual parameters to obtain the starting point of screw disassembly, and finally guide the disassembly device close to the disassembly starting point, and remove the screws on the lifting lugs of the power battery pack sequentially along the disassembly path to complete the power battery pack. disassembly. An automatic disassembly system is also provided, including a lifting and cleaning module, a data acquisition module, an image acquisition module, an image processing module, a calculation module, a comparison module, a disassembly module, and the like. The automatic disassembly method and system provided by the present invention can automatically disassemble the power battery pack, improve the disassembly efficiency, and avoid safety problems in the disassembly process.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, and more specifically, relates to a method and system for automatically disassembling scrapped and recycled power battery packs of new energy vehicles. Background technique [0002] In recent years, with the gradual improvement of infrastructure such as charging stations for new energy vehicles, the scale of the domestic new energy vehicle market will continue to expand. According to statistics, the number of new energy vehicles has exceeded 1 million for three consecutive years, showing a continuous high-speed growth trend. By the end of 2020, the number of new energy vehicles in the country will reach 4.92 million, accounting for 1.75% of the total number of vehicles. According to the calculation of the service life of new energy vehicles, in the next five years, new energy vehicles will usher in the first peak of scrapping and recycling. [0003] There are huge differences in processes, tec...
