Description

Technical Field

[0001] The present invention relates to the technical field of battery disassembly and recycling, and in particular to a battery module disassembly device and method. Background Art

[0002] With the popularity of new energy electric vehicles and other products using rechargeable battery technology, a large number of battery modules have gradually entered retirement period as their service life increases. In the daily use of new energy vehicles, there are often some scrapped and damaged batteries that need to be replaced. With the development of battery technology and the increasing market demand for environmental protection and sustainable development, the disassembly and recycling of battery modules has become an important link. It not only helps to protect the environment, but also realizes the effective use of resources.

[0003] For example, the existing Chinese patent (CN213701204U) discloses an integrated recycling and disassembly equipment for lithium battery modules, including a disassembly workbench, a fixed slide is installed above the disassembly workbench, a lifting slide is installed on the surface of the fixed slide, the upper end of the lifting slide is connected to the driving cylinder installed on the top of the fixed slide through a telescopic rod, a cutting mechanism is installed on the lifting slide, a cleaning box is installed on one side of the disassembly workbench, a cleaning drive motor is installed on the upper end of the cleaning box, and a stirring rod is rotatably connected to the lower end of the cleaning drive motor through a rotating shaft, a transportation mechanism is installed on one side of the cleaning box, a cutting drive motor is installed on the cutting mechanism, and one end of the cutting drive motor is rotatably connected to a cutting wheel through a rotating shaft.

However, the current recycling of battery modules is mainly based on extensive crushing pre-treatment. Among them, the crushing treatment method will damage healthy battery cells, and the various materials of the module will be crushed and mixed together, making it difficult to distinguish and classify different materials, and then it is difficult to further process the crushed materials, which greatly increases the difficulty of recycling.
