The invention discloses automatic 
electrolyte injection equipment for batteries. The automatic 
electrolyte injection equipment comprises a stander, a closed box body covering the stander, an electric cabinet independently arranged outside the closed box body, as well as a loading vacuum transition cabin, a 
drying and cooling mechanism, a loading 
manipulator, a loading conveyer belt, an 
insulation resistance test mechanism, a loading code-scanning and weighing 
manipulator, a pre-injection weighing mechanism, a turntable loading mechanism, an injection 
electrolyte circulation standing turntable mechanism, an unloading code-scanning and weighing 
manipulator, a post-injection weighing mechanism, an electrolyte supplement 
station, a rubber plug 
insertion station, an unloading 
conveyor belt, an unloading transfer tray and an unloading vacuum transition cabin which are sequentially arranged on the stander along the battery conveying direction, and the automatic electrolyte 
injection equipment further comprises a 
drying tray used for bearing a battery. Therefore, through the cooperation of each part, the whole 
automation degree of the equipment is improved, and the production efficiency is greatly improved; meanwhile, the equipment ensures that no bubble exists in the injected electrolyte, realizes stable and reliable electrolyte injection, improves the battery quality and prolongs the service life of the battery.
