Description

Diagonal pliers for battery disassembly

technical field

The utility model relates to the technical field of battery production, in particular to a diagonal pliers used for battery disassembly.

Background technique

With the development of the economy, new energy lithium batteries are getting more and more attention and development. During the production of lithium batteries, it is often necessary to disassemble and rework due to reasons such as equipment, personnel, and craftsmanship; in addition, battery analysis also requires battery analysis. Disassemble. At present, the dismantling tools for lithium batteries are mainly vise, hammer, etc. Because of their low compatibility with lithium batteries, dismantling is troublesome, laborious, inefficient, and it is easy to cause short circuit of the battery, which poses a safety hazard.

Therefore, it is a problem to be solved in the current battery production field to provide a convenient, practical, high-efficiency, and high-safety disassembly tooling.

Utility model content

The purpose of the utility model is to provide a diagonal pliers for battery dismantling, which is labor-saving and safe for battery dismantling operations.

The purpose of this utility model can be realized through the following technical solutions:

A diagonal pliers for battery disassembly, comprising a handle and a hinged first blade and a second blade, the first blade includes a first main blade, and a blade is fixed in the middle of the first main blade The triangular secondary blade has grooves on the surface of the first main blade at the bottom of the secondary blade; the second blade includes a second main blade, and the surface of the second main blade is fixed with a second Bosses parallel to the main cutting edge.

In a further solution, the handles are connected by springs.

In a further solution, the handle is covered with a non-slip rubber sleeve.

In a further solution, the groove is a cuboid structure perpendicular to the first main cutting edge, and the groove and the secondary cutting edge are connected in an arc.

In a further solution, the boss is arc-shaped.

In a further solution, the length of the secondary blade protruding from the first main blade is 4-5 mm, so as to avoid a short circuit caused by contact with the battery winding core when the battery is disassembled.

When in use, make the corner of the aluminum shell close to the cover plate close to the main blade of the first blade and the second blade of the diagonal pliers. After applying force through the handle, the secondary blade will tear the aluminum shell to a small opening, and then rotate the diagonal pliers , through the leverage of the arc-shaped boss on the second blade, continue to tear the aluminum shell, and make the scattered aluminum shell slide out along the groove. Therefore, when the diagonal pliers rotate one circle along the cover plate, the battery is disassembled, the operation is simple, the safety is high, and it can be widely popularized.

Compared with the prior art, the beneficial effects of the utility model are:

(1) The utility model adds a triangular secondary blade to the middle of the first main blade of the first blade, so that when the battery is disassembled, the tip of the secondary blade contacts the aluminum shell of the battery for rapid positioning and spreading; Moreover, the length of the secondary blade protruding from the first main blade is 4-5 mm, so as to avoid short circuit caused by contact with the battery winding core when the battery is disassembled, thereby improving safety.

(2) A groove is provided on the blade surface extending from the secondary blade, so that when the battery is disassembled, the scraps of the disassembled aluminum shell are separated along the groove, avoiding the contact between the scraps of the aluminum shell and the core. Batteries are short-circuited to improve safety.

(3) Add a circular arc-shaped boss to the second blade of the diagonal pliers, and hold it against the battery during disassembly, so as to improve the disassembly efficiency through the principle of leverage.

detailed description

As shown in Figures 1 and 2, a diagonal pliers for battery disassembly includes a handle 1 and a hinged first blade 2 and a second blade 3, the first blade 2 includes a first main blade 4, In the middle of the blade edge of the first main blade 4, a triangular secondary blade 5 is fixed, and a groove 6 is provided on the blade surface of the first primary blade 4 at the bottom of the secondary blade 5; the second blade 3 includes a second The main cutting edge 7 and the second main cutting edge 7 are fixed with a boss 8 parallel to the second main cutting edge 7 .

In a further solution, the handles 1 are connected by a spring 9, and the handle 1 is covered with a non-slip rubber sleeve.

In a further solution, the groove 6 is a rectangular parallelepiped structure perpendicular to the first main cutting edge 4 , and the groove 6 is connected to the secondary cutting edge 5 in an arc shape.

In a further solution, the boss 8 is arc-shaped.

In a further solution, the length of the secondary blade 5 protruding from the first main blade 4 is 4-5 mm, so as to avoid a short circuit caused by contact with the battery winding core when the battery is disassembled.

When disassembling the battery, clamp the first blade and the second blade of the diagonal pliers to the corner of the aluminum shell of the battery close to the cover plate, and apply force through the handle. Through the leverage of the arc-shaped boss on the second blade, the aluminum shell is continuously torn apart, and the scattered aluminum shell is slid out along the groove. Therefore, when the diagonal pliers rotate one circle along the cover plate, the battery is disassembled, the operation is simple, the safety is high, and it can be widely popularized.

The above content is only an example and description of the structure of the utility model. Those skilled in the art make various modifications or supplements to the described specific embodiments or replace them in similar ways, as long as they do not deviate from the utility model.
