Detailed Description

The utility model is further described below in connection with specific embodiments.

Example 1

As shown in fig. 1 and 2, the electric core cutting device of the embodiment comprises a mounting bracket 1 and a conveying belt 2 arranged on the mounting bracket 1, wherein a guide assembly 3, a pressing assembly 4 and a cutting assembly 5 are sequentially arranged on the mounting bracket 1.

The conveying belt 2 is used for conveying the battery cell body forwards in the whole cutting process; the guide component 3 is used for guiding and limiting the battery cell body in the conveying process to a certain extent, and can adjust the initial posture of the battery cell body at the same time so as to facilitate the later cutting operation; the compaction assembly 4 compacts the conveyed battery cell body from the upper part of the battery cell body so as to ensure the stability of the battery cell body in the cutting process; the cutting assembly 5 performs cutting operation on two ends of the compressed battery cell body, and provides a basis for subsequent fine disassembly.

Specifically, as shown in fig. 3, the guide assemblies 3 are oppositely arranged with two groups, and are respectively located at two sides of the conveying belt 2. The guide assembly 3 comprises a flange 31, a first guide 32 and a first driver 33. The first driving piece 33 drives the two flanges 31 which are oppositely arranged to be close to or far away from each other to adjust the distance between the two flanges 31, so that the device is suitable for guiding and conveying of the battery cells with different sizes. At the same time, the provision of the first guide 32 ensures the stability of the flange 31 during movement. Wherein, the first guiding element 32 can be in the form of a matching form of a sliding rail and a slideway.

According to the battery cell cutting device, the front end of the blocking edge 31 is provided with the arc-shaped guide section, so that the inlet formed by the two blocking edges 31 is in a reduced horn mouth shape, and the design is more beneficial for the battery cell body to enter between the two blocking edges 31.

In addition, the flange 31 is further provided with a pressing plate 34, and the pressing plate 34 can play a certain role in stopping two ends of the battery cell body, so that the battery cell body can be prevented from side turning in the later cutting process.

As shown in fig. 4, the compressing assembly 4 is erected above the conveyor belt 2, and includes a pressing bar 41, a second guide 42, a second driving member 43, and a supporting frame 44. The second driving member 43 is disposed on the supporting frame 44, and an output end of the second driving member 43 is connected to the top of the pressing bar 41. One end of the second guide member 42 penetrates through the top of the supporting frame 44 and then is connected with the pressing bar 41.

When the battery cell is in operation, the second driving piece 43 is started to drive the pressing strip 41 to move downwards to press the battery cell body downwards, and at the moment, the second guiding piece 42 plays a role in guiding and limiting the movement of the pressing strip 41. It should be noted that, on the one hand, the pressing force of the pressing bar 41 on the cell body needs to ensure that the cell body can be in a stable state during the cutting process, and on the other hand, the normal forward movement of the cell body cannot be affected. For this reason, in the present embodiment, the molding 41 is a fluent strip, so that rolling friction is generated between the molding 41 and the battery cell body. Under the same conveying condition, the downward pressure of the pressing strip 41 on the battery cell body can be increased so as to fully ensure the stability of the battery cell body.

As shown in fig. 5, the cutting assembly 5 includes opposite cutting machines 51, and opposite sides of the cutting machines 51 are provided with cutting blades 54 for cutting the cell body.

The cell body can be divided into a main body, an upper cover plate and a lower cover plate after being cut. The main body part is continuously conveyed forward to the next working procedure for fine disassembly; the upper cover plate and the lower cover plate enter the recovery box along the chute 7, and the electrolyte of the liquid flows out of the chute 7 through the liquid leakage hole to be recovered independently, so that solid-liquid separation can be well realized by the design.

In addition, dust can be generated in the cutting process of the battery cell body, so that the working environment of the site is polluted and the physical and psychological health of workers is influenced. Therefore, in this embodiment, the dust remover 6 is disposed at the mounting bracket 1 near the cutting assembly 5, so as to collect and recover the dust generated during the cutting process in time, thereby reducing the pollution.

According to the battery cell cutting device, through the mutual matching of the guide component 3, the pressing component 4 and the cutting component 5, the battery cell body can be continuously cut, the battery cell body is in a stable state in the cutting process, the cutting precision is guaranteed, and accordingly the integrity of an internal core roll is maintained.
