Acid adding machine for storage battery

Abstract

The invention relates to an acid adding machine for a storage battery. The acid adding machine comprises a base, a machine body, a first platform, a second platform, a third platform, measuring cups, vacuum tubes and a lifting device, wherein the top of each measuring cup is provided with an acid adding branch tube; each measuring cup is communicated with a corresponding vacuum tube below the measuring cup through an acid conveying branch tube; the bottom of each vacuum tube is connected with a hose; and acid adding nozzles are formed at the bottom of the lifting device. The acid adding machine is characterized in that: the bottom of each measuring cup is provided with an electronic scale in which a hole for a corresponding acid conveying branch tube to pass through is formed; each electronic scale is electrically connected with a program control box arranged on one side of the machine body; each vacuum tube is connected with a vacuumizing hose; a vacuumizing pump is electrically connected with the program control box; and an acid adding valve is arranged on each acid conveying branch tube. The acid adding machine has the advantages that: the volume of acid liquor can be highly accurately measured with small errors, and can be automatically set, and the whole acid adding process can be automatically controlled.

Description

technical field [0001] The invention relates to an acid adding machine, in particular to an acid adding machine for a battery pack. Background technique [0002] As people pay more attention to energy saving and emission reduction, batteries are becoming more and more popular. The acid-adding process of the battery is the key that directly affects important performances such as the length of the battery's primary discharge and the length of the cycle life. Especially the process of adding acid to the battery pack. The current process of adding acid to the battery pack is: put the battery pack into the acid feeder → automatically lower the six acid feed nozzles and insert them into the acid injection nozzles on the battery → measure the acid solution in the measuring cup → Acid solution is injected into the vacuum tube → vacuum pumped and acid injected into the battery (repeat 3-4 times) → the acid injection nozzle rises automatically, and the acid injection process is comp...

Problems solved by technology

Because the liquid level will fluctuate when adding acid to the measuring cup, it will affect the accuracy of acid measurement, so that the amount of acid added to each battery is different, or even not enough, which seriously affects the performance and life of the battery pack.

In addition, once the amount of acid liquid measured by the liquid level sensor is set, it is difficult to change it, which will affect the scope of use of the acid dosing machine
