Description

Technical Field

[0001] The present invention relates to the technical field of battery disassembly equipment, and in particular to a lithium battery shell disassembly equipment. Background Art

[0002] Lithium battery is a common rechargeable battery. The organic electrolyte in lithium battery will pollute the environment. Therefore, dismantling and recycling used lithium batteries can not only reduce the pollution of organic electrolyte to the environment, but the recovered metal materials can also be reused, which can save resources to a certain extent.

[0003] During the disassembly and recycling process of lithium batteries, it is often necessary to first disassemble the battery shell and separate the battery shell, inner core, and electrolyte before the waste can be recycled. Most existing battery disassembly equipment only has a fixing mechanism and a cutting and disassembly mechanism. The fixing mechanism fixes the battery, and then the cutting and disassembly mechanism cuts and disassembles the battery shell on one side. Therefore, when disassembling the multiple side shells of a square battery, it is necessary to manually change the side or use an additional mechanical structure to flip it over, and then perform a secondary positioning and calibration before continuing to cut the shell. This is not only cumbersome to operate, but also reduces the battery disassembly rate. At the same time, the existing disassembly mechanism cannot effectively realize the classification operation of the battery shell and inner core, which is not conducive to the recycling operation of the shell and inner core.

As the rotary clamping mechanism 2 is loosened, the lithium battery inner core will pass through the guide mechanism 5 and slide along the second guide plate 75 into the collection frame 1 6, thereby realizing the classified collection of the lithium battery outer shell and inner core. After the single-sided rotary clamping mechanism 2 is connected to the adjacent guide mechanism 5, the rotary clamping mechanism 2 can simultaneously adjust the distance between the guide mechanisms 5 when clamping or loosening the lithium battery to be disassembled, further limiting the lithium battery or allowing the disassembled battery inner core to pass through the guide mechanism 5 and then be guided by the classification mechanism 7, thereby realizing the classified collection of the battery inner core and the battery outer shell.

The gap between the dismantling body 1 and the bottom end thereof can be used as a solution chamber to store coolant, so that the coolant can be pumped into the spray mechanism 3 by the water pump 14. The coolant sprayed by the spray mechanism 3 during the lithium battery cutting and dismantling process flushes and cools the cutting mechanism 4, thereby preventing the cutting mechanism 4 from being damaged by overheating. The flushing of the coolant can also take away the electrolyte and debris leaked during the lithium battery cutting and dismantling, so that the electrolyte and debris can be wrapped by the coolant and then pass through the collecting frame 1 6 and the collecting frame 2 8 to reach the solution chamber, thereby realizing the classified collection of the lithium battery shell, inner core and electrolyte; and the sliding collecting frame 1 6 and the collecting frame 2 8 can be conveniently withdrawn from the dismantling body 1, which facilitates the removal and centralized processing of the battery shells and inner cores collected in the collecting frame 1 6 and the collecting frame 2 8;
