Description

Technical Field

[0001] The present invention relates to the technical field of disassembly tools, and in particular to a disassembly device for aluminum shell power batteries. Background Art

[0002] In recent years, through active guidance and the promulgation and implementation of relevant policies, my country has enabled the new energy vehicle industry market to enter a rapid development stage, which has led to extensive research and development of automotive power batteries (the "heart" of new energy vehicles).

[0003] During the research and development and production of power batteries, the batteries need to be disassembled for performance analysis in order to intuitively and accurately obtain the internal information of the batteries, providing important reference value for subsequent power battery research and development and production. At the same time, battery disassembly is an important part of the recycling of power batteries. The recycling of waste power batteries can avoid problems such as waste of resources and environmental pollution.

[0004] At present, power batteries are mainly disassembled by manual tools such as vises, diagonal pliers, and screwdrivers. After one side is disassembled, the battery needs to be manually turned over to disassemble the other side. Manual disassembly of batteries has the disadvantages of low efficiency, high labor costs, and high safety hazards. In addition, manual disassembly precision is not high, and the disassembly tool is easy to contact the polarity terminals of the battery, damaging the battery and causing a short circuit. It is also easy to affect the internal parts of the battery cell, affecting the accuracy and effectiveness of subsequent battery analysis data.

[0005] Therefore, it is necessary to design a battery disassembly device that can be applicable to power batteries. Summary of the invention

[0006] The purpose of the present invention is to design a disassembly device for aluminum shell power batteries that is easy to operate, highly automated, and highly safe. During the disassembly operation of aluminum shell power batteries, the operator has very few manual operations, which protects the operator's safety on the one hand, and can complete the disassembly work in one go without turning the battery over on the other hand. At the same time, the disassembly device of the present invention can disassemble batteries of different sizes and structures, which is convenient for industrialized and large-scale quantitative disassembly operations.
