Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted storage battery assembly, and in particular discloses an electrolyte filling device for a vehicle-mounted storage battery. Background Art

[0002] The on-board battery is also called the car battery. Its main function is to convert chemical energy into electrical energy. By releasing electrical energy, it can provide power for the car's starting system, lighting system and other electrical equipment. When the vehicle starts, the battery will discharge to provide power to the starter, thereby starting the engine. When the engine is not powered enough or not started, the battery will also provide power for electrical appliances in the car. When the engine is powered normally, the battery will collect and store electrical energy for future use.

[0003] The structure of a vehicle battery mainly includes the following key parts: positive and negative plates, electrolyte, shell, and terminals; the lead dioxide on the positive plate reacts chemically with the pure lead on the negative plate to generate lead sulfate, while releasing electrons to form current to power the car's electrical equipment. When assembling a vehicle battery, the assembler needs to inject the electrolyte containing dilute sulfuric acid solution between the grids inside the vehicle battery, and make the electrolyte level and density meet the relevant standards, so as to ensure the normal use of the vehicle battery.

[0004] At present, during the production and assembly process of vehicle batteries, assemblers need to carry the vehicle batteries to the workbench, inject electrolyte between the grids with a handheld injection gun, and move the vehicle batteries away from the workbench after the electrolyte injection is completed, so as to carry out the electrolyte filling operation of the next vehicle battery. It can be seen that in the current process of adding electrolyte to vehicle batteries, assemblers need to frequently transfer vehicle batteries, which has high labor costs; and the dilute sulfuric acid solution contained in the electrolyte is highly corrosive. Once the electrolyte leaks during the filling process, it will not only cause burns to the assembler's skin, but also may corrode the assembly equipment, shorten the service life of the equipment, cause the assembly operation to be interrupted, and greatly affect the assembly efficiency.
