Description

Technical Field

[0001] The utility model relates to the technical field of battery aluminum foil processing, in particular to an auxiliary bench for processing automotive battery aluminum foil. Background Art

[0002] Battery aluminum foil is the aluminum outer layer wrapped outside the battery. Specifically, for a lithium battery, its main structure includes chemical materials such as electrolytes filled inside the battery and an aluminum shell wrapped outside the lithium battery.

[0003] During the production and processing of battery aluminum foil, the battery aluminum material (blank) needs to be wound on a winding rod and unwound for transmission. The aluminum material skin for processing the lithium battery shell is obtained by rough cutting to get intermediate aluminum material, and the intermediate aluminum material is further subdivided and cut to obtain aluminum material skin with a specific width size, which is processed into aluminum strips for wrapping through subsequent cutting. However, during the processing, since the aluminum material is relatively soft, during the cutting process, the aluminum foil material at the cutting part is prone to wrinkling, and defects such as uneven cut edges are likely to occur, affecting the cutting quality. Therefore, we designed an auxiliary bench for processing automotive battery aluminum foil to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the prior art, and propose an auxiliary bench for processing automotive battery aluminum foil. The aluminum foil roll is sleeved on the unwinding component for unwinding. The clamping component can fix the end of the aluminum foil body to unfold the aluminum foil body. During cutting, the U-shaped plate abuts against the upper end of the aluminum foil body to fix the aluminum foil on both sides of the part to be cut. The air cylinder continues to drive the mounting plate to move downward, so that the cutting knife can pass through the through hole and contact the aluminum foil body for cutting. The operation is simple, reducing the problem of wrinkling of the aluminum foil body on both sides of the cutting knife during the cutting process and ensuring the cutting quality.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

The end of the aluminum foil body 6 passes through the first pressing rod 7 and the second pressing rod 16 in sequence and is located between the lower pressing plate 12 and the upper pressing plate 14. When the electromagnet is energized, an attractive force can be generated, causing the upper pressing plate 14 to move downward. The upper pressing plate 14 and the lower pressing plate 12 act together to fix the end of the aluminum foil body 6. Starting the second servo motor 9 to drive the threaded rod 10 to rotate can, under the action of its thread engagement, cause the guiding slider to drive the support plate 11 to move away from the aluminum foil roll 5, so that the aluminum foil body 6 can be unfolded. The scale line can measure the length of the unfolded aluminum foil body 6.

[0029] During cutting, the support plate 11 stops moving. The cylinder 18 drives the mounting plate 19 to move downward, making the U-shaped plate 20 abut against the upper end of the aluminum foil body 6, fixing the aluminum foil on both sides of the cutting position, reducing the problem of wrinkles on the aluminum foil body 6 on both sides of the cutting knife 24 during cutting, and ensuring the cutting quality. The cylinder 18 continues to drive the mounting plate 19 to move downward, enabling the cutting knife 24 to pass through the through hole 25 and abut against the aluminum foil body 6. The electric slider slides back and forth in the electric slide rail 23, driving the cutting knife 24 to slide back and forth to cut the aluminum foil body 6, and the operation is simple.

[0030] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto.
