Description

Technical Field

[0001] This utility model relates to the field of battery welding technology, specifically a battery bottom penetration welding machine. Background Technology

[0002] With the energy crisis and environmental problems becoming increasingly severe, and with the country's strong support for the new energy industry, key technologies for power battery cells have gradually matured, and various types of power battery cells have been widely used in electric cars, electric motorcycles, electric bicycles, solar energy, mobile communication terminal products, and energy storage products.

[0003] Penetrating welding at the bottom of the battery tightly bonds the core to the bottom of the casing, ensuring stable operation under various complex conditions and extending battery life. Traditional battery bottom welding processes are done manually, which is not only labor-intensive but also slow, has inconsistent welding quality, uneven weld lines, and rough weld surfaces. Unstable welding quality leads to loosening of the battery during use, resulting in a short lifespan and failing to meet user needs. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a battery bottom penetration welding machine to solve the problems mentioned in the background. This invention features a novel structure, simple and quick operation, reliable welding quality, high operational reliability, a streamlined and stable overall structure, and a small footprint, meeting customer site requirements. It employs a dual-station alternating manual loading and unloading system. The module is conveyed to the welding position, and the battery positioning fixture automatically positions and flips the battery so that the bottom faces upward. The X and Y axes of the galvanometer are automatically aligned for welding, reducing labor intensity, ensuring consistent welding quality, and resulting in no damage to the battery casing after welding. The welded surface is smooth and uniform, without obvious spatter, and there are no instances of incomplete welding or over-welding. The core is tightly welded to the bottom of the casing, ensuring stable battery operation under various complex conditions, extending battery life, and guaranteeing battery safety.
