Description

Technical Field

[0001] This utility model relates to the field of battery disassembly technology, specifically a battery disassembly device. Background Technology

[0002] Lithium-ion batteries, with their high energy density and long cycle life, have been widely used in electric vehicles, energy storage systems, and portable electronic devices. With the rapid increase in battery usage, the recycling and disposal of used batteries has become an increasingly prominent issue. Lithium-ion batteries are typically encapsulated in an aluminum casing and contain positive and negative electrodes, a separator, and an organic electrolyte. These contain limited metal resources such as lithium, cobalt, and nickel, and the electrolyte itself is flammable and poses potential environmental hazards. Therefore, efficient and safe recycling of used lithium-ion batteries not only contributes to resource recycling but also effectively reduces the risk of environmental pollution.

[0003] In the quality inspection stage of battery recycling or production, it is often necessary to disassemble the battery to obtain information about the internal cell structure or to separate materials. This process requires precise removal of the metal casing while preserving the internal stacked core structure intact, avoiding damage to the separator, electrode short circuits, or electrolyte leakage. Damage to the internal structure during disassembly may lead to serious safety accidents such as short circuits, thermal runaway, or even fire and explosion, severely affecting operational safety and subsequent processing efficiency.

[0004] Currently, the disassembly of lithium-ion batteries mainly relies on manual operation, which suffers from high labor intensity, low efficiency, and poor consistency. Furthermore, operators are susceptible to injury from sharp metal edges or hazardous substances. Some technologies employing mechanical or semi-automatic disassembly methods often use tools such as cutting with knives or lasers to open the casing. However, these methods present challenges such as difficulty in controlling the cutting depth, heat accumulation, and the risk of puncturing the battery casing and damaging the internal cells. Therefore, a battery disassembly device is proposed. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 In this embodiment of the utility model, a battery disassembly device includes: Base 1; Clamping assembly 2, disposed on base 1, is used to clamp and fix the battery cell; Lifting component 3 is mounted on base 1, and laser rangefinder 4 is installed on lifting component 3; The bracket 5 is mounted on the lifting assembly 3 and is driven by the lifting assembly 3 to move vertically. The bracket 5 is equipped with a drive assembly 6, and a cutting assembly 7 is mounted at the end of the drive assembly 6. When disassembling the battery cell, the bracket 5 moves up and down through the lifting assembly 3, while the drive assembly 6 on the bracket 5 drives the cutting assembly 7 to move horizontally, thereby adjusting the position of the cutting assembly 7 and disassembling the battery cell by the cutting assembly 7.

[0018] Specifically, both the clamping component 2 and the lifting component 3 are installed on the upper surface of the base 1 to fix their relative positions. The lifting component 3 is a lifting structure such as a linear module. The linear module is existing technology and will not be described in detail here. The lifting component 3 is vertically installed on the upper surface of the base 1. The bracket 5 is installed on the movable slide of the linear module and moves with the movable slide to ensure that the movement of the bracket 5 on the lifting component 3 is in the vertical direction, so as to avoid the direction deviation of the cutting component 7 during the adjustment of the cutting depth. The drive component 6 includes a hydraulic pump. The hydraulic pump is equipped with a proportional control valve and an accumulator (not shown in the figure). The hydraulic pump can provide a continuously adjustable pressure of 0.5–5 MPa, with an output force fluctuation of ≤±2%. At the same time, the incompressible characteristics of hydraulic oil ensure smooth operation and avoid instantaneous impact during disassembly. It is determined that the cutting component 7, which is installed at the end of the drive component 6, can complete the disassembly and assembly of the battery. During the cutting process, if the cutting resistance increases suddenly or the cutting depth is too large (touching the inside), an emergency stop is triggered with an error of <0.01 mm.

[0019] Please see Figure 1 In one embodiment, preferably, it further includes a control system, which is connected to the clamping assembly 2, the laser rangefinder 4, the lifting assembly 3, the driving assembly 6 and the cutting assembly 7 respectively. Its control principle is the prior art and will not be described in detail here.

[0020] Please see Figure 1 In one embodiment, preferably, the support 5 is equipped with a travel track 9, which is arranged along the movement direction of the drive component 6 and is slidably connected to the cutting component 7.

[0021] Specifically, the number of walking tracks 9 is not limited. In this embodiment, there are two walking tracks 9. The two walking tracks 9 are parallel to each other and fixedly installed on the surface of the bracket 5. Both walking tracks 9 are slidably engaged with the cutting component 7. The walking tracks 9 not only limit the range of motion of the cutting component 7, but also further constrain the direction of movement of the cutting component 7 by being set in parallel, effectively preventing the driving component 6 from deviating when driving the cutting component 7, thereby avoiding failure to cut the battery casing.

[0022] Please see Figure 1-3 In one embodiment, preferably, the cutting assembly 7 includes a fixed base 71 that slides with the travel track 9, a servo motor 72 is mounted on the fixed base 71, and a saw blade 73 for disassembling the battery cell is mounted at the end of the servo motor 72.

[0023] Specifically, the fixed base 71 is slidably connected to the two traveling rails 9, and the fixed base 71 is L-shaped, with its two sides connected to the ends of the traveling rails 9 and the drive assembly 6, respectively. A servo motor 72 is installed inside the fixed base 71, and a saw blade 73 is installed at the output end of the servo motor 72. The saw blade 73 is circular and made of non-metallic material. Specifically, the saw blade 73 is a ceramic circular saw blade with a thickness of 0.2 mm to avoid the possibility of short circuit caused by contact between the metal material and the inside of the stacked core.

[0024] Please see Figure 1 In one embodiment, preferably, a rotating base 8 is installed at the bottom of the clamping component 2. The rotating base 8 is connected to the base 1. Furthermore, the rotating base 8 can drive the clamping component 2 to rotate synchronously, thereby driving the battery connected to it to rotate synchronously, so as to cut and remove the metal shell of the battery at different positions.

[0025] Please see Figure 2 In one embodiment, preferably, the clamping assembly 2 includes a base 21 connected to the rotating base 8. Two cylinders 22 are mounted on the base 21, and clamping blocks 23 are mounted on the telescopic ends of the two cylinders 22. Furthermore, the battery is clamped by driving the two clamping blocks 23 to open and close synchronously through the two cylinders 22.

[0026] Please see Figure 2 In one embodiment, preferably, the adjacent end faces of the two clamping blocks 23 are provided with silicone buffer pads for contacting the battery casing. Furthermore, a pressure sensor is provided between the clamping blocks 23 and the silicone buffer pads. The silicone buffer pads are used to protect the battery casing and prevent pinching or deformation, while the pressure sensor is used to monitor the clamping force in real time. When the clamping force exceeds a set threshold, the control system automatically releases the pressure to prevent deformation of the battery casing.

[0027] The working principle and usage process of this utility model are as follows: First, the battery to be disassembled is placed on the clamping component 2, and a buffer clamping force is applied by the cylinder 22 to clamp and fix the battery; then, the battery shell thickness is input into the control system to automatically generate a cutting path; during cutting, the drive component 6 drives the saw blade 73 to cut along the predetermined path, and the feed speed is adaptively adjusted according to the resistance. At the same time, the laser rangefinder 4 monitors the cutting process synchronously. After the cutting on one side is completed, the rotating base 8 drives the battery to rotate to cut the other side. After the aluminum shell is peeled off, the clamping component 2 automatically releases the battery, completing the disassembly.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0029] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
