Description

Technical Field

[0001] The utility model relates to the technical field of battery assembly, in particular to an auxiliary mechanism for inserting an aluminum shell battery core into the shell. Background Art

[0002] During the production process of aluminum shell batteries, after the current collector of the battery cell is welded to the connecting piece, the cover plate is welded to the connecting piece, the connecting piece is bent, a layer of Mylar film is wrapped on the surface of the battery cell, the Mylar film is adhered to the cover plate, and the battery cell is placed in the aluminum shell. The reason for wrapping the Mylar film is because when the battery cell is placed in the shell, there is a risk of the shell opening scratching the battery cell, so the Mylar film needs to be wrapped on the surface of the battery cell to prevent the battery cell from being damaged.

[0003] In automated equipment, when the battery cell is put into the shell, the cover is directly pressed to push the battery cell into the shell. There will be a slight downward misalignment of the cover relative to the battery cell, causing the Mylar film to droop downward. This will cause the misaligned parts of the cover and Mylar film to scrape the shell when the battery cell is put into the shell, damaging the battery. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention will now be further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the relevant components of the present invention.

[0021] According to the technical solution of the present invention, without changing the essential spirit of the present invention, those skilled in the art may propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are merely illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0022] The technical solution of the present utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0023] Example 1, as Figure 1-2 As shown, an auxiliary mechanism for inserting aluminum-cased battery cells into the shell comprises a shell insertion assembly 1 and a cover plate positioning assembly 2. The shell insertion assembly 1 is used to push the battery cell 4 into the shell 3 via a robot arm, and the robot also places the shell 3 on a workstation and limits its position. This is the basic structure of current battery assembly. The cover plate positioning assembly 2 pushes the cover plate 8 and battery cell 4 into the shell 3. The surface of the battery cell 4 is coated with a Mylar film, which adheres to the cover plate 8, pushing the cover plate 8 and battery cell 4 together during insertion.

[0024] The cover positioning assembly 2 includes a cell top block 5, a lifting cylinder 6, and a pushing module 7. The lifting cylinder 6 and the pushing module 7 can be said to be the driving mechanism of the cell top block 5, which drives the cell top block 5 to complete the pushing action of the cover 8 and the battery cell 4.

[0025] The lifting cylinder 6 and the pushing module 7 are respectively installed on the top of the shell entry component 1. When working, the pushing module 7 pushes the lifting cylinder 6 to move back and forth in the horizontal direction, and the working end of the lifting cylinder 6 is vertically downward and connected to the battery cell top block 5 in the vertical direction, driving the battery cell top block 5 to push the cover plate 8 and the battery cell 4. A positioning component is provided on the side of the battery cell top block 5 close to the cover plate 8 to limit the pushed cover plate 8 so that the battery cell 4 can be pushed into the shell 3 more accurately.

[0026] The positioning assembly includes a first positioning cylinder 9 and a second positioning cylinder 10, which are respectively installed on both sides of the battery cell top block 5. The working end of the first positioning cylinder 9 is provided with a first positioning block 12, and the working end of the second positioning cylinder 10 is provided with a second positioning block 13. In the above scheme, the first positioning block 12 and the second positioning block 13 are respectively L-shaped block structures, and their working ends squeeze the two sides of the cover plate 8 toward the middle. By providing two positioning cylinders and cooperating with two positioning blocks, the two sides of the cover plate 8 are limited, facilitating accurate pushing into the housing 3.

[0027] In Example 2, based on Example 1, the positioning assembly further includes an air gripper 11, which is mounted in the middle of the cell top block 5. A third positioning block 14 is provided at the working end of the air gripper 11. In the above scheme, the air gripper 11 clamps the upper and lower portions of the cover plate 8, while the third positioning block 14 is an L-shaped strip with its working end pressing the upper and lower sides of the cover plate 8 toward the center. By providing an additional air gripper 11 in conjunction with the third positioning block 14, the upper and lower sides of the cover plate 8 are limited, effectively positioning the cover plate 8 on all sides, facilitating precise insertion into the housing 3.

[0028] Among them, Figure 1 and Figure 2 As shown, the push module 7 includes a push cylinder, a linear guide, and a top plate. The push cylinder is mounted on one side of the top of the shell assembly 1, and the lifting cylinder 6 is mounted on the top plate. The top plate is mounted on the top of the shell assembly 1 via linear guides on both sides of the bottom. One side of the top plate is connected to the working end of the push cylinder. The push of the push cylinder drives the top plate to move along the linear guide, thereby driving the lifting cylinder 6 to move horizontally. The lifting cylinder 6 drives the battery cell top block 5 to complete the pushing action of the cover plate 8 and the battery cell 4.

[0029] When implementing this plan, the specific work is as follows:

[0030] The robot (not shown) transfers the battery cell 4 into the shell assembly 1, the working end of the lifting cylinder 6 extends, the battery cell top block 5 moves downward, the pushing module 7 moves in the direction of A1, the cover plate 8 contacts the battery cell top block 5, and starts to push the cover plate 8.

[0031] The pushing module 7 stops moving, the working ends of the first positioning cylinder 9 and the second positioning cylinder 10 are retracted, the working end of the air claw 11 is retracted, the first positioning block 12, the second positioning block 13, and the third positioning block 14 position the cover 8, and the pushing module 7 moves along the A1 direction, driving the battery top block 5 to move along the A1 direction, and installing the battery cell 4 into the shell 3.

[0032] The working ends of the first positioning cylinder 9 and the second positioning cylinder 10 extend, the working end of the air claw 11 extends, the pushing module 7 moves in the opposite direction of A1, driving the battery cell top block 5 to move in the opposite direction of A1, and the working end of the lifting cylinder 6 is retracted to complete the shell insertion action.

[0033] Example 3, based on Example 1 or 2, please refer to Figure 3 and Figure 4 The cell top block 5 comprises a top block body, a connecting block 15, and a push plate 16, forming an L-shaped structure. The connecting block 15 is located at the top of the top block body and is fixedly connected to the working end of the lifting cylinder 6. The push plate 16 is located on the side of the top block body, and the positioning assembly is installed on the top block body.

[0034] As a preferred solution, in one embodiment, the top block body is a hollow frame structure, the middle part of which is used to install the air claw 11, and both sides of the top block body provide space for installing the positioning components, mainly providing installation space for the first positioning cylinder 9 and the second positioning cylinder 10.

[0035] In one embodiment, the upper and lower portions of the push plate 16 are provided with guide bevels 17, each with a groove in the middle of the guide bevels 17. The guide bevels 17 are provided to guide the cover plate 8 when it is pushed, allowing it to fit against the surface of the push plate 16, thereby facilitating positioning of the cover plate 8 by other positioning components.

[0036] In one embodiment, the push plate 16 has two side plates with escape grooves 18, the diameter of which is larger than the positive and negative electrode covers on the cover plate 8. The escape grooves 18 are mainly used to avoid the positive and negative electrode covers on the cover plate 8, and the positive and negative electrodes of the battery cells 4 are installed from this area, so they need to be avoided to avoid damage during pushing.

[0037] In summary, this solution modifies the existing cover plate positioning assembly 2, positioning the four edges of the cover plate 8 so that the cover plate 8 maintains its relative position with the housing 3 before inserting the battery cell 4 into the housing. This prevents the Mylar film from scraping against the housing opening and damaging the cell when the cell 4 is inserted. This improves the accuracy of the cell 4 insertion into the housing, prevents misalignment when pushing the cover plate 8 and the cell 4, reduces the chance of cell 4 damage during insertion, and ensures battery quality.
