Description

Technical Field

[0001] The present invention relates to the technical field of battery recycling equipment, and particularly relates to a disassembly and recycling mechanism for waste lithium batteries. Background Art

[0002] Lithium batteries are a common type of rechargeable battery. The organic electrolytes in lithium batteries can pollute the environment. Therefore, disassembling and recycling waste lithium batteries can not only reduce the environmental pollution caused by organic electrolytes, but also the recycled metal substances can be reused, which can save the waste of resources to a certain extent.

[0003] During the disassembly and recycling process of existing waste rechargeable batteries, it is often necessary to first remove the battery casing and separate the battery core and electrolyte before the waste materials can be recycled. There are two methods for disassembling lithium batteries: manual disassembly and mechanical disassembly. When manually disassembling the battery, the operator needs to manually cut the battery casing and then slowly peel off the entire battery casing. Therefore, not only is the operation cumbersome, time-consuming and laborious, but also it is extremely easy to cause harm to the operator's body due to the sharp cut of the battery casing or improper operation of the cutting machine. Most of the existing battery disassembly equipment only circumferentially cuts the top and bottom casings of the battery through mechanical equipment, and then forcibly pushes the entire battery core out of the casing through a push-pull structure. This method not only causes damage to the core, resulting in leakage of the electrolyte, but also causes damage and deformation of the casing due to improper operation, increasing the difficulty of pushing and disassembling the battery core. Summary of the Invention

[0011] Further, the stripping member includes a fixing rod, a limiting block, and a stripping rod; the fixing rod is connected to the lifting connection end of the lifting and cutting structure; the limiting block is located at the upper end of the fixing rod; the stripping rod is rotatably arranged at one end of the fixing rod away from the lifting connection end, the stripping rod has an "L" - shaped structure, a groove facing the laser cutter is provided on the lower rod body of the stripping rod, and a torsion spring is provided on the rotating shaft of the stripping rod, so that the stripping rod keeps fitting with the limiting block under normal conditions.

[0012] Further, the clamping member includes a turntable, a second telescopic column, and a pressing plate; the turntable is rotatably connected to the inner wall of the disassembly body; the second telescopic column is connected to the bottom of the turntable; the pressing plate is connected to the telescopic end of the second telescopic column.

[0015] The beneficial effects of the present invention compared with the prior art are as follows:

[0016] (1) By arranging a lifting and cutting structure, a clamping member, and a rotary support member inside the disassembly body, the present invention enables the cutting end of the lifting and cutting structure to adaptively adjust the horizontal cutting position and the vertical cutting position according to the size of the side shell plate of the battery on one side (width side or length side) to be cut. When the laser cutter at the cutting end performs laser cutting on the two corners of the side shell plate of the battery on one side (width side or length side), the side shell plate can be peeled off from the outside of the inner core by the synchronously moving stripping member, realizing the automatic disassembly between the inner core and the side shell plate of the battery, avoiding the problems brought by manual disassembly, also avoiding the damage or cracking of the inner core or the shell caused by the traditional push - pull disassembly structure, reducing the leakage of electrolyte, and reducing the disassembly difficulty of the battery inner core.

[0017] (2) In the present invention, a material guiding plate, an electrolyte collecting box, and a supporting seat with a liquid guiding groove are arranged in the inner cavity of the disassembly machine body, and a housing collecting box is arranged at the bottom of the disassembly machine body. During the disassembly process of the battery, the electrolyte can pass through the cutting opening and fall along the direction of the battery. The electrolyte is introduced into the electrolyte collecting box through the liquid guiding groove on the supporting seat for centralized collection. The disassembled outer shell side plates will also slide into the housing collecting box along the material guiding plate for collection, thereby realizing the separation and recycling of the battery housing and the electrolyte.

[0018] (3) In the present invention, a clamping member is composed of a turntable, a telescopic column II, and a pressing plate, and a rotating support member is composed of a supporting seat, a rotating shaft, a motor, a gear I, and a gear II. The clamping member can be adaptively clamped according to the size of the battery to ensure that batteries of different sizes do not shake during the cutting and disassembly process. The rotatable clamping member and the rotating support member can change the clamping direction of the battery, which is beneficial for adjusting the cutting and disassembly position of the battery with the cutting end of the lifting and cutting structure. At the same time, the setting of the laser cutter enables it to vertically cut the outer shell side plate as the lifting connection end descends. The stripping member will descend synchronously as the lifting connection end descends to ensure that the stripping member is stuck into the cut seam to peel the outer shell side plate from the outside of the inner core, realizing the automatic disassembly of the battery inner core and the outer shell side plate, avoiding the problems brought by manual disassembly, avoiding damage to the inner core or the outer shell, reducing the leakage of the electrolyte, and reducing the difficulty of battery disassembly.
