Description

Technical Field

[0001] The present invention relates to the technical field of power batteries, and in particular to a power battery shell cutting and coring integrated machine and a processing method thereof. Background Art

[0002] With the development of the power battery industry, the number of power batteries on the market continues to increase, and as a result, the number of power batteries that are scrapped after use is also increasing. For these retired power batteries, the traditional method usually adopts the production process of overall crushing and then separation and extraction to recycle the material resources therein. However, this method has obvious limitations: on the one hand, it makes the recycling of material resources more difficult and costly; on the other hand, overall crushing may cause the leakage of harmful substances and pollute the environment.

[0003] In order to address the above issues and achieve a more environmentally friendly and efficient recycling process, the industry has gradually turned to the method of disassembly first and then classified recycling. This method allows targeted recycling according to the different components and material characteristics after disassembly, which not only improves recycling efficiency but also reduces the risk of environmental pollution. However, in early practice, disassembly work mainly relies on manual operation, which is not only inefficient, but also increases labor costs. It is also difficult to ensure the safety and consistency of the disassembly process.

[0004] In the prior art, in order to improve the shortcomings of manual disassembly, a more automated device has emerged, such as first cutting the battery shell with a shell cutting device, and then taking out the battery cell with a coring device. However, the design of such devices is often too complicated, especially in the coring process, where a complex mechanical structure is required to ensure that the battery cell can be smoothly separated from the battery shell. This complexity not only increases the purchase cost of the equipment, but also increases the cost of daily maintenance, limiting the possibility of its widespread application.

[0005] Therefore, the inventors redesigned a power battery shell cutting and coring integrated machine and a processing method thereof to solve the above problems. Summary of the invention
