Description

TECHNICAL FIELD

[0001] The present application relates to the field of lithium battery disassembly, in particular to a square single lithium battery cell fine disassembly device and process thereof. BACKGROUND

[0002] In the current square single lithium battery cell disassembly field, many related technologies and devices have been developed and applied. For example, a square battery disassembly device disclosed in Chinese patent CN218224855U includes a bracket, a cutting mechanism, a lifting table, and a lifting drive assembly. The device achieves the disassembly of square batteries to some extent, but in actual application, such traditional disassembly methods expose many problems.

[0003] The conventional disassembly method usually uses a clamp to secure the battery first, then uses saw cutting, laser cutting, or water jet cutting to cut along the pre-set cutting line on the square aluminum shell, thereby separating the aluminum shell and the cover plate assembly, then performing vertical side cutting, and then using an expanding shell device to separate the aluminum shell side and the cell, and finally taking out the cell by a clamping piece. The lithium battery disassembly and separation device disclosed in patent CN207834457U uses a similar operation process. However, this method has obvious defects, the operation steps are complex, and there is a lack of close continuity between each step. After each operation step is completed, the battery position needs to be adjusted or the tool needs to be replaced, which makes it difficult to improve the overall work efficiency and cannot meet the needs of large-scale production or efficient research.

[0004] In addition, during the cutting process, due to the precision limitations of the cutting equipment and the complexity of the battery structure, the cell may be damaged to varying degrees. For example, improper parameter setting during laser cutting may cause local overheating of the cell, affecting the performance of the cell; water jet cutting may leave water stains, affecting the electrical performance of the cell. Such damage to the cell not only hinders the subsequent precise analysis of the internal structure and performance of the cell, but also reduces the recycling quality and reuse value of the cell material in the battery recycling field.

[0033] This embodiment provides a refined dismantling device for square single-cell lithium battery cells. Compared with the prior art, it only requires placing the square single-cell lithium battery on the vertical cutting mechanism 2. The vertical cutting mechanism 2 drives the square single-cell lithium battery to be transported downward. During the transport process, the outer shell of the end cap is vertically cut. The vertically cut square single-cell lithium battery enters the horizontal cutting mechanism 4. The horizontal cutting mechanism 4 transports the square single-cell lithium battery to the right.

[0034] In a preferred embodiment, the vertical cutting mechanism 2 described above can be adopted as follows: Figure 2 The structure shown illustrates that the vertical cutting mechanism 2 includes a vertical conveyor belt 21, a feeding pad 22, a feeding frame 23, and a cutting machine I 24. Two vertical conveyor belts 21 are symmetrically arranged on the top left side of the worktable 1, with opposite conveying directions on both sides. A feeding hole is provided on the top of the worktable 1 between the two vertical conveyor belts 21. The feeding pads 22 are evenly spaced and installed on the conveyor belts of the vertical conveyor belts 21, symmetrically installed on the two vertical conveyor belts 21. A square single-cell lithium battery is horizontally placed on the feeding pad 22 between the two vertical conveyor belts 21 and moves downwards under the action of the vertical conveyor belts 21. The conveyor system is as follows: a feeding frame 23 is positioned between vertical conveyor belts 21, and the vertical conveyor belts 21 and the feeding frame 23 combine to form a front-opening concave feed inlet. Square single-cell lithium batteries are placed through the top of the feed inlet. The feeding frame 23 limits the rear and left and right sides of the square single-cell lithium batteries.

The limiting structure I 3 comprises a limiting plate I 31, a spring 32 and a roller I 33. The limiting plate I 31 is slidingly arranged on the front side of the discharging frame 23 through a shaft. The upper portion of the limiting plate I 31 is inclined outwardly to prevent the square single lithium battery conveyed downwardly from colliding with the limiting plate I 31. The spring 32 is connected between the limiting plate I 31 and the discharging frame 23, and the spring 32 allows the limiting plate I 31 to have a buffering space. The roller I 33 is arranged in the middle portion of the limiting plate I 31 in a rotating manner, and is used to reduce the friction between the square single lithium battery and the limiting plate I 31.

[0039] The transverse cutting mechanism 4: the square single lithium battery subjected to vertical cutting falls on the upper surface of the transverse conveying belt 41. Under the action of the transverse conveying belt 41, the square single lithium battery is conveyed to the right side. When the square single lithium battery passes through the cutting machine II 43, the cutting machine II 43 cuts the shell of the square single lithium battery from the upper side and the lower side.
