Zusammenfassung:The utility model relates to the technical field of battery production, and discloses an auxiliary welding device for a sealing nail of a battery liquid injection opening. The battery liquid injection port sealing nail welding auxiliary device comprises a base and a nail pressing assembly, the nail pressing assembly comprises a plurality of pressing needles, the nail pressing assembly is provided with a pressing shaft coaxial with a sealing nail, the pressing needles are evenly distributed with the pressing shaft as the axis, and the pressing needles pressed on a to-be-pressed face can expose the welding position of the sealing nail. According to the welding auxiliary device, when laser is hit at any position of the sealing nail, the pressing needle provides acting force for the sealing nail to resist laser dotting, the welding sequence does not need to be considered, and the situation that the sealing nail inclines and tilts due to uneven stress in the laser pre-welding process of the sealing nail is effecti
