Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery disassembly technology, and in particular to a battery disassembly tool. Background Technology
[0002] In the lithium battery production process, the weld depth and width of processes such as cover welding, peripheral welding, and sealing welding need to be inspected to check whether the product quality meets the standards. Inspecting the weld depth and width requires disassembling the battery; however, this places high demands on the disassembly operator's skills, as they must ensure the integrity of the battery top cover while guaranteeing safety during the disassembly process. Battery disassembly first involves cutting around the aluminum casing along the edge of the top cover, then separating the top cover from the casing, and finally removing the internal core. However, currently, battery disassembly mainly uses tools such as utility knives and diagonal pliers. These tools are inefficient and require highly skilled operators. If the force and depth of the disassembly are not properly controlled, it will not only lead to poor disassembly results but also increase safety risks, potentially causing battery short circuits, fires, or injuries to the operator.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] In view of the problems existing in the prior art, the purpose of this utility model is to provide an embodiment of a battery disassembly tool that overcomes the problems of low disassembly efficiency and high technical requirements for operators.
[0029] Example
[0030] To achieve the above objectives, this utility model provides the following technical solution: a battery disassembly tool for removing the top cover of a battery, see attached document. Figure 1It includes: a positioning fixture 1 and a sawing mechanism 2; the sawing mechanism 2 is used to cut and separate the top cover of the battery from the battery casing; the positioning fixture 1 is used to fix the battery casing and the top cover of the battery; the wheel saw 21 of the sawing mechanism 2 passes through the cutting groove 122 on the top of the positioning fixture 1 to cut the welding position of the top cover of the battery and the battery casing below the positioning fixture 1.
[0031] In one feasible implementation, the positioning clamp 1 is a semi-enclosed structure, including a tray plate 11 and a positioning plate 12. The tray plate 11 is used to support the battery casing, and the positioning plate 12 is used to position and enclose the top cover of the battery.
[0032] In the specific implementation process, the side of the positioning plate 12 is provided with a pole positioning hole 121, which is used to fix the welding position of the battery top cover and the battery shell. This welding position is the cutting position of the battery 3, located at the top of the battery. After being fixed, it can prevent damage to the battery top cover 31 during the cutting process.
[0033] In one feasible implementation, such as Figure 4 As shown, the sawing mechanism 2 also includes a bolt 22 connected to the wheel saw 21. The wheel saw 21 is circular and located on the lower front end of the sawing mechanism 2. The bolt 22 is located on the upper front end of the sawing mechanism 2. The height of the bolt 22 is adjusted by adjusting the nut 221 of the bolt 22, thereby adjusting the cutting depth of the wheel saw 21. The specific principle is as follows:
[0034] Reduce cutting depth:
[0035] 1. First, loosen the screw (used to fasten bolt 22, not shown in the figure) located in the middle screw hole of the handle head through which bolt 22 passes in a counterclockwise direction;
[0036] 2. Then turn the top nut 221 counterclockwise to loosen the bolt 22, and you can press the bolt 22 down;
[0037] 3. Press the bolt 22 down to the required height (as the bolt 22 is pressed down, the wheel saw 21 will be gradually lifted up, and the downward depth of the wheel saw 21 and the battery top cover will gradually decrease).
[0038] 4. Tighten the middle screw and the top nut 221 clockwise in sequence;
[0039] To increase the cutting depth, simply pull bolt 22 upwards to the required depth.
[0040] Specifically, the sawing mechanism 2 also includes a fastener 24, which is located at the center of the wheel saw 21 and is fixed to the front end of the sawing mechanism 2.
[0041] In one feasible implementation, the sawing mechanism 2 further includes a handle 25 and a first roller 23. The first roller 23 is disposed on the rear side of the wheel saw 21 near the handle 25 and supports the sawing mechanism 2 on the top of the positioning fixture 1. It can roll freely when the wheel saw 21 of the sawing mechanism 2 is cutting.
[0042] In one feasible implementation, the sawing mechanism 2 further includes a second roller 26, which is disposed at the bottom of the bolt 22 and is symmetrical about the vertical axis of the tangent line between the wheel saw 21 and the cutting groove 122.
[0043] In one feasible implementation, the handle 25 adopts a hollow design.
[0044] For the battery disassembly process using battery removal tools, see [link / description]. Figure 2 and Figure 3 ,as follows:
[0045] First, place the battery 3 on the positioning fixture 1, so that the battery terminals 32 are respectively placed in the corresponding positioning holes 121 of the positioning fixture 1; then, adjust the height of the bolts 22 by tightening the nuts 221 to keep the sawing structure 2 at a fixed cutting depth; then, make the wheel saw 21 of the sawing mechanism 2 cut along the cutting groove 122 of the positioning fixture 1 to cut the two long sides of the top of the battery 3, and use a utility knife to cut the two short sides of the top of the battery 3; finally, remove the top cover 31 of the battery.
[0046] In the above embodiment, the height of the bolt 22 is adjusted by tightening the nut 221, thereby adjusting the cutting depth of the sawing structure 2. This makes the cutting position more accurate, preventing damage to the internal structure of the battery or deformation of the casing that would prevent the core from being removed, and even causing a short circuit and fire. The addition of rollers 23, in conjunction with the wheel saw 21, enables rolling cutting, making the disassembly process simpler, faster, less strenuous, and more efficient. The handle 25 features a hollow design, which not only provides anti-slip properties and enhances its aesthetics but also reduces material waste.
