Description

Technical Field

[0001] This utility model relates to the field of automatic production equipment for new energy batteries, and specifically to a battery sealing and welding device and its battery sealing machine. Background Technology

[0002] One crucial process in battery manufacturing is electrolyte injection. The electrolyte in a lithium-ion battery acts as a medium for charging and discharging, conducting ions between the positive and negative electrodes. After battery assembly, the electrolyte is quantitatively injected into the battery. This process involves two steps: first, injecting the electrolyte into the battery; and second, ensuring the injected electrolyte thoroughly wets the internal electrodes and separator. The immersion time affects the production cost of lithium-ion batteries. After electrolyte injection, the injection port and battery surface must be cleaned to remove any residual electrolyte or other substances before proceeding to the next welding and sealing process to seal the injection port.

[0003] Based on the sealing process after battery electrolyte filling, during the sealing process, a sealing pin needs to be inserted into the battery electrolyte filling port, and then the sealing pin is welded to the edge of the electrolyte filling port for sealing. Since the connection between the sealing pin and the battery electrolyte filling port is a ring-shaped structure, a battery sealing welding device with adjustable welding direction needs to be designed to address the welding sealing problem at this point. Utility Model Content

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention addresses the shortcomings and deficiencies of existing technologies by independently developing and designing a battery sealing welding device and battery sealing machine that uses a single-rotation power drive and utilizes the reaction force provided by the toothed connection to achieve movement along an L-shaped path, thereby adjusting the welding direction or angle in real time.
