Description

Technical Field

[0001] The present invention relates to the technical field of tab cutting, and in particular to a battery tab cutting device. Background Art

[0002] Tabs are key raw materials for lithium-ion polymer batteries and are widely used in batteries for electronic devices such as mobile phones, Bluetooth, and laptops. They are of great significance to the energy supply of modern electronic devices.

[0003] Tab cutting plays an essential role in battery production. Tabs are typically placed on both sides of a battery cell. To address this, the current technology commonly uses a pneumatic cylinder to drive a "guillotine"-like cutting device to cut the tabs. This approach not only meets production needs but also ensures the smooth execution of key battery production processes. However, the tabs are relatively soft, making them prone to curling during cutting, necessitating further flattening.

[0004] Application number: CN202111413694.8, discloses a battery tab cutting mechanism with double-sided tabs. The battery tab cutting mechanism with double-sided tabs in this application can complete the cutting of the tabs at both ends at one workstation, and the space occupied is also extremely small; this device can arbitrarily switch the cutting length of the tabs according to the program.

[0005] However, after the cutting operation related to the above patent is completed, the tabs are prone to curling, so they need to be further flattened before the finished product can be obtained for use in the next step. Summary of the Invention
